INTRODUCTION

The Halifax Regional Water Commission (Halifax Water) is soliciting proposals for a 2019 Sewer Mainline Lining Project – Phase 1 which includes the application of a cured-in-place pipe (CIPP) liner to rehabilitate aging wastewater, and combined (wastewater and stormwater) sewer mains. The detail project requirements are further defined in this document.

BACKGROUND

Background Information The use of trenchless rehabilitation technologies involves combining both construction and manufacturing practices into a single process. This integration of manufacturing and construction has evolved into a specialized industry with its own unique engineering principles and practices. As a result of this rapidly changing industry and the integration of manufacturing with construction, it is important to qualify the technologies and the installer (Proponent) of the technology. This ensures that the technology (design, installation method, etc.) can stand up to reasonable engineering scrutiny and the installation Proponent has satisfactorily demonstrated that they have the capacity, expertise, resources and established procedures, including Quality Assurance and Quality Control (QA/QC) to execute the rehabilitation effectively prior to contract award.

Interested proponents are required to submit a proposal in response to this RFP. At a minimum the information requested in Section 6 and the corresponding Appendix A is to be provided. Proponent proposal submissions will be evaluated. Those achieving a minimum technical score will have their financial submission reviewed. The financial submission is be a completed tender document included as Appendix B. Of the tenders reviewed the intent is to award to the Proponent who submits the lowest bid compliant tender. Further details are provided in this document.

2.2 Pre-Proposal Conference (Optional)

Each Proponent must completely satisfy itself as to the exact nature and existing conditions of the 2019 Mainline Trenchless Lining Project - Phase 1 requirements and for the extent and quality of work to be performed. Failure to do so will not relieve the successful Proponent of its obligation to carry out the provisions of the contract.

The successful proponent will be responsible to identify any locations along the sewer mains which require remedial work prior to the lining installation. Halifax Water (or others as appointed) will undertake the adjacent construction work in advance of the lining installation.

Proponents are welcome to attend a Pre-Proposal conference to be held at the Halifax Water Cowie Hill Office on May 16, 2019 at 2:00pm AST. A conference call option will also be available for any proponents that are unable to attend in person. Halifax Water and consulting representatives will be on hand to address any questions pertaining to the project and to conduct any overview of the specification requirements of materials and work methods for rehabilitation of mainline sewers. Note: Separate individual conferences will not be granted. All proponents interested participating in this conference will be required to confirm by May 15, 2019 prior to attending by emailing [email protected]

SCOPE OF WORK

General

This contract requires the use of cured-in-place pipe (CIPP) technology for the completion of the sewer rehabilitation as identified within this document. The method of cure for the CIPP technology is open to any of the following methods; Hot Water, Steam, or UV cured CIPP products. The proponent shall identify within their submission their intended curing method for executing the Work.

Depending on the proposed method of cure, the proponents submission shall comply with the appropriate CIPP specification included within the tender document (see Appendix B). Specifically these tender specification sections are as follows:

1. Hot Water/Steam Cured (Section 33 11 05): Proponent must comply with thisspecification for any CIPP products that rely on hot water or steam cure methodsto achieve performance requirements.

2. UV-Cured (Section 33 11 10): Proponent must comply with this specificationfor any CIPP products that rely on UV cure methods to achieve performancerequirements.

Failure by the proponent to demonstrate they have abided by the correct specification may be grounds for non-compliant submission.

The scope of the 2019 Sewer Mainline Trenchless Lining – Phase 1 project includes all necessary design, labour, equipment, and materials required to successfully rehabilitate the wastewater sewer mains identified and in accordance with the requirements in this document. In general this includes sewer main lining, reinstatement and restoration of all disturbed areas, traffic control, overall management of the work including safe work practices and all approval, permissions and necessary permits.

Overview May 2019

OVERVIEW

This document is a Supplementary Specification to the Standard Specification for Municipal Services, developed by the Nova Scotia Roadbuilders - Consulting Engineers of Nova Scotia Joint Committee on Contract Documents.

The Halifax Regional Water Commission (“Halifax Water”), in response to a need to standardize their specification practices, reduce review and approval time, and regulate the specifications produced by their consultants, have adopted the Standard Specification for Municipal Services.

As an active member on the Joint Committee during the Standard Specification’s development, Halifax Water became familiar with, and contributed input to, the Standard Specification’s development.

Whereas the Standard Specification is intended for both sewer and water projects throughout the province of Nova Scotia, Halifax Water’s concern is limited to water and wastewater systems within the limits of the Halifax Regional Municipality, additional specification requirements will be provided as supplementary specifications.

These project documents have been prepared for use with and require being read in conjunction with The Standard Specifications for Municipal Services as published by the Nova Scotia Roadbuilders – Consulting Engineers of Nova Scotia Joint Committee on Contract Documents. Copies of The Standard Specification for Municipal Services are available from the Joint Committee on Contract Documents, 455 Colby Drive, Dartmouth, NS B2V 2K4; Telephone (902) 430-2534, (902) 492-6749 OR EMAIL: [email protected].

26. SCHEDULE OF WORKS



Section 00 74 00

Page 14 May2019

26.1 Submit to Halifax Water, for their review and approval, a schedule of the proposed

specifically identified Works. All of the mainline sewer rehabilitation is to be completed in 2019. The schedule shall be reviewed with Halifax Water prior to commencement of the planned works.

26.2 Notify Halifax Water of specific start/finish times for all procedures in order that Halifax Water inspection staff may co-ordinate their schedules to ensure suitable levels of inspection. Give this notification a minimum of 48 hours prior to the start time of each phase of work.

26.3 The order of Work is, in general, the responsibility of the Contractor and will be as indicated in the detailed work plan and schedule. However, Halifax Water reserves the right to modify the order of work based on Halifax Water’s needs.

27. SITE INVESTIGATION

27.1 Investigate each site; determine the existing site conditions, any obstructions, or any other problem, which may affect the completion of the proposed Works. No additional payment will be made on account of difficulties to complete the Works because the Contractor failed to investigate the site prior to commencement of the Work.

28. POLICE RECORD CHECKS

28.1 All Contractor personnel who will be working for Halifax Water must obtain a “Police Record Check” (PRC). Refer to Appendix B. PRC shall be in place prior to an individual working on the project.

29. WEATHER CONDITIONS

29.1 Review the Environment Canada Weather forecast prior to commencement of lining operations. Where the anticipated weather conditions are such that anticipated sewer and/or sewer service flows may exceed the Contractor’s bypass pumping capacity or may cause potential basement flooding (blocked laterals due to the liner), commencement of construction shall be delayed until favourable weather is forecast.

30. FLOW CONTROL AND BYPASS

30.1 During lining, provide for bypassing and pumping of mainline sewage to maintain sanitary sewage flow in upstream sections of the sewer being lined.

30.2 During lining, make provisions to provide for building bypassing of multi-unit residential, commercial, and industrial buildings (as determined by the Engineer) from a clean out or property MH to maintain sanitary sewage services to the property if required.

30.3 Make all necessary arrangements with the owners of each building. Contact all property owners and/or tenants to co-ordinate the repair work to the sewer and minimize any impact on residents and/or businesses.

30.4 During the inspection and rehabilitation, shut off sewer flows in order to enable proper inspection of the pipe invert. After the work is completed, restore flows to normal. Transport excess sewage flows through a closed, leak tight pipeline or other method as approved by the Engineer to the nearest or most economical disposal area.

30.5 On all liner installation dates, maintain on site both a primary and stand-by by-pass pump and pump power supply. Sufficient power supply and hoses must be on site in



Section 00 74 00

Page 15 May2019

order to allow the pump to discharge into the next appropriate downstream sewer section. The stand-by by-pass pump and power supply must be of an equal or better capability than the primary by-pass pump and power supply. Do not disconnect any by-pass pumps or related equipment or remove from the sewer or job site until after all service connections have been reinstated and the Contractor has recorded the post-installation video.

30.6 All by-pass pumping shall be in place and operation prior to the final pre-installation inspection.

30.7 Do not employ any flow control or bypass pumping that has insufficient capacity to maintain flow in the sewer system. It is the Contractor’s responsibility to employ flow control of sufficient capacity. Do not proceed with any work requiring flow control until flow control arrangements are in place that provide sufficient flow control capacity

30.8 All by-pass pumps and related equipment must be silenced equipment or contained within an acceptable sound reduction structure.

30.9 Event of Loss of Redundant Capacity: .1 When circumstances arise requiring the use of redundant capacity and therefore

redundant capacity no longer exists, take action immediately to restore the lost capacity to full function so that redundant capacity is fully restored. If redundant capacity cannot be restored, only critical work already in progress that must be completed (such as lining inversion, curing and liner end opening) will proceed and without delay. No other work continuation (such as lateral reinstatements or CCTV inspection) will take place without a fully functional redundant capacity.

.2 When it is known or suspected that redundant capacity is not or may not be fully functional, do not start work that requires bypass operation.

30.10 Bypass Coordination and Supervision: assign a Bypass Supervisor to manage all bypass pumping operations. Advise the Engineer of this person and provide with 24 hr contact information. When the bypass is required to operate, the supervisor will assure that the bypass system is in full function operation, including fully available 100% redundancy before any work is started for which the bypass is required. When the bypass is in operation, the bypass supervisor will assure that there is continuous presence by a competent person to watch over the bypass including manual checking of upstream levels, pump fuel levels and other indications of potential trouble such as at pump suctions and discharges, discharge conduits and redundancy availability.

30.11 Responsibility for Leaks, Spills and Back-ups: the Contractor shall be responsible for all leaks, spills and back-ups, should they occur and shall take immediate action to restore bypass integrity and make clean-up of any leak, spill or back-up.

30.12 Flow Control Included Limit Provision: .1 Unless specified otherwise in the contract documents (such as for site specific

flow control requirements) the following limit to flow control included in the CIPP lining applies.

.2 Limit of Flow Control Included with Lining Item.

.3 Provide flow control up to 63 litre/sec (1,000 USgpm) as part of the lining item. Such flow control shall include bypass pumping or other means of effecting flow control.

33.3 Contractor's notices must be typed on the Contractor's letterhead and clearly indicate both daytime and after hours local contact telephone numbers. Telephone numbers shall be either local area code or toll free numbers. No work will be allowed to commence without such notices. All Contractor written notice(s) shall be submitted to Halifax Water for approval prior to notice delivery.

33.4 Where circumstances require or as directed by Halifax Water, the contractor is required to verbally advise house or building occupants or owners of work that will affect the occupants or owners and conduct any ongoing liaison that is required to resolve questions or other issues.

33.5 Service interruption notice: .1 Any time a sewer service will be interrupted or limited by rehabilitation

activities, the Contractor shall provide a 24-hour Service Interruption Notice to the affected property. The notice shall be typed on the Contractor's letterhead and clearly indicate both daytime and after hours local contact telephone numbers for the Contractor. The notice shall include notification to the property residents to limit their sewer use, including the use of any mechanical device(s) (e.g. sump or ejector pump, etc.) from discharging to the sewer service lateral, in a manner that may adversely affect the lining process. The Contractor must schedule the sewer service rehabilitation installation accordingly.

.2 No service interruption will be allowed without such 24-hour notification. In the event that the Contractor is unable to install the sewer service rehabilitation on the date stated in the Service Disruption Notice the Contractor must immediately provide written notification of the change of date including the new date for the sewer service rehabilitation installation. After the service line



Section 00 74 00

Page 17 May2019

and connection has been fully returned to service the Contractor shall notify the property that the sewer service is returned to service.

.3 Log record: maintain a log of notices delivered by the Contractor and follow-up activities at each property throughout the Work.

33.6 Damage or loss due to failure to notify: in the event that damage/loss to person or property occurs as a result of the Contractor not notifying the public as per the notification protocol, all such liabilities will be fully borne by the Contractor.

34. PERMITS AND PERMISSIONS

34.1 Obtain any permits and permissions necessary for the Work including permits for disposal of cleaning water and cleaning debris removed from the lateral pipe or mainline sewer in the course of the work. Provide Halifax Water with a copy of the written permission or permit for the disposal of cleaning water or debris, clearly indicating the location and authority giving permission.

34.2 Contractor shall obtain street permits from HRM for all lining locations.

35. TEMPORARY SANITARY FACILITIES

35.1 Schedule the Works in such a way that provisions for portable sanitary facilities are not required for abutting residents and businesses. Minimize interruption of sewer services. For locations where interruption of sewer service for rehabilitation installation is not possible due to the nature of the service (high flows, type of property), sewer service shall be maintained by temporary bypassing or other means (such as collection by tank truck).

37. RESTORATION

37.1 Upon completion, clean up and restore the site to pre-existing or better condition and follow all applicable HRM and Halifax Water construction standards.

38. WARRANTY

38.1 Provide a two (2) year warranty that expressly states the finished pipe will be continuous over the entire length of a new installation and shall be free of dry spots, lifts, excessive wrinkling and folds, and delamination. If these conditions are present, repair the defects at own cost, to Halifax Water’s satisfaction. In the event C.I.P.P. does not fit tightly against the host pipe at its terminal points, seal the space between the pipes with a resin mixture compatible with the CIPP.

PART 1 - GENERAL

1.1 INTRODUCTION

.1 This Standard Specification for Sewer Rehabilitation using Hot Water or Steam Cured-in-Place Pipe (herein referred to as CIPP) is intended to be used in conjunction with site specific requirements as outlined in the contract documents. This standard covers the lining requirements for Halifax Water’s 2019 Sewer Rehabilitation Program. Each CIPP liner run to be installed must be evaluated by the Contractor with respect to this standard in order to ensure site specific considerations to the standard are identified for which additional requirements in the contract documents apply. Inherent in this specification are Specific Liners, which have a suitable design for specific sections of pipe that are identified in the proposal (i.e. Each pipe section will have its own specific design) and Special Liners, which are required when installation conditions are more onerous than covered by the Specific design.

Where the anticipated weather conditions are such that anticipated sewer/drain flows may exceed the Contractor’s bypass pumping capacity or may cause potential service backups, the contractor shall notify the Owner and commencement of any work that impedes sewer flow shall be delayed until favourable weather is forecast.

.2 This clause applies to all sewers (storm, sanitary and combined) to be lined.

PART 2 - PRODUCTS

2.1 SEWER SIZES – NOMINAL VERSUS ACTUAL

.1 The Contract Documents generally refer to nominal sizes for sewers and not the actual inside diameter sizes. The actual inside diameters will typically be slightly different (typically larger) than the nominal value. It is the Contractor’s responsibility to use the sewer size dimensions that are appropriate and proper for rehabilitation purposes including CIPP liner design.

2.2 SEWER SIZE INSIDE DIAMETER TOLERANCES

.1 General

.1 Sewer sizes shown in Proposal and Contract documents are nominal metric sizes. For the purpose of the contract, a nominal sewer size shall include actual sizes within the range shown below.




May 2019

Nominal Size (mm)

Lower Limit of Actual ID

(mm)

Upper Limit of Actual ID

(mm)

200 > 178 ≤ 216

225 > 216 ≤ 241

250 > 241 ≤ 279

300 > 279 ≤ 343

375 > 343 ≤ 419

450 > 419 ≤ 483

500 > 483 ≤ 521

525 > 521 ≤ 572

600 > 572 ≤ 648

675 > 648 ≤ 724

750 > 724 ≤ 800

825 > 800 ≤ 876

900 > 876 ≤ 953

975 > 953 ≤ 1029

1050 > 1029 ≤ 1105

1125 > 1105 ≤ 1181

1200 > 1181 ≤ 1295




May 2019

.2 Where the inside diameter fits within the range for a nominal size, the sewer shall be deemed to be that nominal size for payment purposes. For example, a sewer identified in as a 900 mm that has an actual inside diameter up to 953 mm shall be deemed to be a 900 mm sewer. Whereas a sewer identified in the contract documents as a 900 mm that has an actual inside diameter above 953 mm shall be deemed to be a 975mm sewer.

.3 The applicable sewer size for payment shall be based on the inside diameter that has been determined, by measurement, to be the diameter to be used for sizing the CIPP liner.

.2 Sewer Size for Lining Increased by H2S Corrosion

.1 The sewer sections for rehabilitation by CIPP lining may be internally corroded by H2S induced corrosion. In some sections the corrosion is severe with exposed reinforcing steel. Some sections have exposed gaskets. In determining the inside diameter of the sewer for sizing of the liner, the Contractor shall take into account that most, if not all H2S corroded sections will have enlarged inside diameters, especially after cleaning and preparation. Refer to Section 2.4 on measurements.

2.3 OBJECTIVES FOR CIPP LINING

.1 The objectives for CIPP lining of sewers are to prevent further structural deterioration, prevent corrosion, prevent root intrusion, prevent/reduce infiltration and improve flow characteristics.

.2 CIPP Lining shall be a tight fit to the inside of the existing sewer and conform closely to the shape of the existing sewer without bridging, gaps, or voids.

.3 CIPP lining shall be installed without excavation by installation into existing pipelines through MH access. Exception shall be made when existing MH access is of insufficient size or existing MH location is inadequate.

.4 CIPP liners shall be designed in accordance with the Design Section of this specification.

.5 The term liner means a continuous reach of lining extending over the section to be lined, beginning and ending at manhole inside walls.




May 2019

2.4 CIPP LINER SIZING

.1 General

.1 It is the responsibility of the Contractor to obtain and confirm the necessary lengths and interior dimensions of the sewers to be lined and obtain the appropriate measurements. Size information provided on the drawings or in the Request for Proposal documents are typically nominal sizes and are not necessarily the correct sizes.

.2 The Contractor’s method for obtaining and confirming sizes shall, at a minimum, include measuring the inside diameter of the existing sewer at all manholes (MHs) in the section. Measurement method shall take into account the possibility that the exposed sewer end is a bell and does not represent the inside diameter of the sewer pipe itself. Measurement method shall take into account any debris, encrustation, or other build up in the sewer that could result in an incorrect sizing measurement. The contractor shall also take into account any change in pipe characteristics such as offset joints, change in ovality, partial collapse, broken pipe, etc., which could result in incorrect sizing measurement.

.2 Measurements for Liner Sizing

.1 The Contractor is responsible for the correct diameter sizing and length of the CIPP liners. The Contractor shall not rely on dimensions provided in the proposal documents including drawings or CCTV inspection.

.2 The actual inside size(s) of the sewers for lining shall be verified by measurement prior to any fabrication of the liners. The dimensions used for sizing the liner tubes circumference/perimeter shall take into account potential increase in the sewer inside diameter due to the cleaning and preparation of the sewers for lining.

.3 The length of the liner shall be verified by measurement of the section(s) of sewer to be lined. A sufficient length safety margin shall be added to the measured length to assure that the liner extends from beginning of the MH to the end MH over the length of the installed liner run.

.4 Measurements shall be provided to the Owner on request.

.3 Liner Sizing Measurements Made Prior to Cleaning and Preparation




May 2019

.1 Where the sewer inside diameter is measured for sizing the CIPP liner prior to cleaning and preparation, the measurement method shall employ using sizing rods, mandrels or other device that can penetrate through or scrape away any material buildup (e.g. corrosion deterioration) in order to obtain the inside diameter that is expected to occur after cleaning and preparation of the sewer. Measurements by tape measure shall not be acceptable.

.2 Measurements shall be taken at both ends of all USMH-DSMH sewer sections to be CIPP lined.

.3 Where flow control is required to obtain proper measurements, the Contractor shall provide flow control.

.4 Variable Sewer Inside Diameter for Lining

.1 In the event that an inside diameter variance exists along the sewer section to be lined to the extent that the liner may be oversized or undersized for zones of the lining run, the Contractor shall present the liner sizing situation and anticipated lining results (regarding fit and finish) along with a recommendation for liner sizing for the MH-MH section to the Owner. The Owner shall discuss the situation with the Contractor and in conjunction with the Contractor determine and approve the sizing of the liner for the installation.

.2 It is understood that in zones of the sewer where a liner may be oversized, there will be excess material in the form of wrinkles and fins in the finished liner. In zones of the sewer where the liner is undersized, the finished liner may stretch out resulting in a decrease in wall thickness. The Owner shall take the foregoing into account in the determination of the approved liner sizing.

.3 The determination of the sewer sizing for lining will consider the best compromise between zones of excess liner material and zones where the liner could be thinned out by stretching or where the stretch may not be sufficient resulting in a liner that is not tight fitting.




May 2019

.5 Pipe Size for Payment

.1 Payment for CIPP lining shall be based on the nominal size that has a size range that includes the inside diameter after cleaning and preparation. Refer Section 2.2 for size ranges. The inside diameter after cleaning and preparation shall be the dimension used to size the CIPP liner for payment purposes.

.2 For example where the contract identifies the nominal size as 825 mm and the actual inside diameter for lining after cleaning and preparation is within the range shown in Section 2.2 for nominal 825 mm, payment will be made for a nominal 825 mm. However if for a contract nominal 825 mm, the actual inside diameter for lining after cleaning and preparation is greater than the maximum inside diameter for nominal 825 mm shown in Section 2.2 , payment will be made based on the nominal size with a range containing the final inside diameter for lining.

.6 Substantiation for Increase in Nominal Size for Payment

.1 Where an increase in nominal size for payment is warranted, the Contractor shall provide substantiation of the final size for lining that verifies the final size for lining based on measurements of the sewer or other substantiation method that is acceptable to the Owner.

2.5 EVALUATION OF MH-MH SECTIONS FOR LINING

.1 Prior to any liner preparation, the Contractor shall evaluate each MH-MH sewer section to be lined. This evaluation shall determine whether the Proposal Liner Design submitted with the proposal submission yields a liner that is suitable for the MH-MH sewer section being evaluated or whether a Special Liner Design is required.

.2 This evaluation shall also determine whether any excavated repairs are required before lining and whether the sewer section, overall, is a suitable candidate for lining.

.3 The Contractor’s evaluation shall include field identification and CCTV review identification for when one or more of the following installation parameters are in exception to the Specific Design parameters.




May 2019

Parameter Exception to Proposal Design

Ovality Greater than 3%

Water Table Location

Less than 1.0 m below ground surface

Sewer Invert Deeper than Proposal Liner Design

Size Different than the Proposal Liner Design

Live Load Greater than the Proposal Liner Design

.4 From the evaluations of all MH-MH sewer sections to be lined, the Contractor shall prepare and maintain a Liner Sections Record (LSR) of every MH-MH section for lining. The LSR shall show whether the MH-MH section is suitable for a Proposal Design Liner or whether a Special Design Liner is required. When a Special Design Liner is required the LSR shall show the existing sewer parameters that are in exception to the Specific Liner Parameters.

.5 The LSR shall use an Excel spreadsheet and called the Liner Sections Record. The contractor shall utilize Halifax Water’s MH identification (ID) numbers. When requested, the Contractor shall provide an updated LSR to the Owner.

.6 The LSR shall be constructed in such a way that all MH-MH sections to be lined can be readily identified along with the exceptions to Specific Design Parameters for that section. When a Special Design is made for a MH-MH section the liner design thickness shall be identified in the LSR along with the Special Design parameters.

.7 The format of the LSR shall be as determined by the needs of the Contractor to record and track the evaluation process and the needs of the Owner for use of this data.

2.6 PROPOSAL DESIGN LINER VERSUS SPECIAL DESIGN LINERS

.1 For each sewer section for lining identified in the proposal there will be an approved Proposal Liner Design for each MH-MH section of lining and a corresponding Proposal Liner. The Proposal Liner Design shall be submitted by the Contractor with the proposal submission. See Sections 3.10 and 3.11 .




May 2019

.2 Where it is determined that a Proposal Design Liner has insufficient thickness for the intended MH-MH section of lining, the Contractor shall provide a Special Design which takes into account the changed parameters that made the Proposal Design Liner unsuitable for the location. On the approval of the Owner, the Contractor shall install the Special Design Liner and be paid accordingly.

.3 The determination of whether a Special Design and correspondingly a Special Design Liner are required shall flow from the Contractor’s Evaluation of MH-MH Sections for lining work.

2.7 LINER THICKNESS INCREASE

.1 Where a Proposal liner design thickness is insufficient for the installation as determined by a Special Design, the liner thickness shall be increased to satisfy the Special Design thickness. The thickness increase shall be the minimum required incremental thickness of the liner tube to satisfy the Special Design thickness. Thickness increments shall be as per the Schedule of Quantities and as set forth below.

Increment # Thickness Increment

1 1.0 mm

2 > 1.0 mm ≤ 2.0 mm

3 > 2.0 mm ≤ 3.0 mm

4 > 3.0 mm ≤ 4.0 mm

5 > 4.0 mm ≤ 5.0 mm




May 2019

.2 A thickness increment pay item only applies when the Contractor was required to increase the nominal liner tube thickness over the Specific Design liner to achieve the additional thickness required by the Special Design.

.3 In the proposal response, the Contractor shall, for each sewer section, list the specific nominal tube size to be used for the Specific Design Liner. See Statement E in the Request for Proposal.

.4 Where the Contractor considers that the increased in-place thickness necessitated by a Special Design can be achieved without increasing the nominal tube thickness over the specific nominal tube thickness, then the installation may be made with the specific nominal tube thickness at the Contractor’s discretion. However regardless of the nominal tube used, the in-place liner thickness shall meet the requirements of the Special Design. In the case where the Contractor opts to use the Proposal Design nominal tube thickness, there will not be a thickness increment change for the nominal tube thickness and no increased thickness payment will apply.

.5 Where the Special Design Liner has been approved by the Owner, the Contractor will be paid for the liner thickness increase in accordance with the appropriate item in the Schedule of Quantities and Prices. Compensation for extra thickness will not be given in cases where liners are installed without prior approval by the Owner, through corresponding certified design approved by the Owner.

PART 3 - EXECUTION

3.1 FLOW CONTROL AND BYPASS

.1 Purpose

.1 Provide for bypassing and pumping of mainline sewage to maintain sanitary sewage flow in upstream sections of the sewer being lined. The contractor shall not let the upstream sewers surcharge beyond a reasonable amount, so as not to create any issues.

.2 During the CCTV inspection of pre and post rehabilitation, sewer flows shall be bypassed in order to enable proper inspection of the pipe invert.




May 2019

.2 General

.1 Flow Control means reducing or eliminating flow in the sewer section or sewer sections where lining is to be installed for the purpose of allowing the liner installation and facilitating associated activities, such as CCTV inspections. The method of achieving flow control is the responsibility of the Contractor subject to approval by the Owner.

.2 For the mainline sewer, flow control may include: Complete bypass pumping of the sewer section(s) requiring flow control, plugging and back-up of the upstream mainline sewer, pick-up of flows by vacuum tanker truck.

.3 For service connections, flow control may include: Temporarily backing up the service connections during lining installation (with notice and instructions to property occupants), bypass pumping of flows from service MHs, pick-up of service flows at service MHs (or other intercept points) by vacuum tanker truck.

.3 Complete Flow Control Required For:

CCTV inspection V2

Insertion and Curing of the CIPP liner until flow through thelined sewer section can be restored when the liner ends areopened for flow.

CCTV inspection V3

.1 Complete flow control means that there shall be no flow in the sewer section(s) and any fluid remaining in the sewer section shall be insignificant to the point that it will not interfere with or negatively affects the process underway during flow control, such as liner installation, liner cure or CCTV inspections.

.2 No flow control or bypass pumping shall be employed that has insufficient capacity to maintain flow in the sewer system. It is the Contractor’s responsibility to employ flow control of sufficient capacity. No work requiring flow control shall proceed until flow control arrangements are in place that provide sufficient flow control capacity

.4 Flow Control During Other Work




Section 33 11 05

Page 22 May 2019

.1 Partial or complete flow control may be required during other work when the presence of flow in the pipe negatively affects the quality of that work. In general, the use and amount of flow control for other work will be at the Contractor’s discretion except when in the opinion of the Owner flow control is necessary for the Contractor to properly perform the work and obtain required results. Other work includes:

.1 Cleaning and preparation of the sewer section(s) to be lined

.2 Reinstatement of service connections into the lined sewer

.3 Any extra CCTV inspections required by the Owner

.5 Bypass Pumping

.1 When bypass pumping is employed for flow control, the Contractor shall meet the following requirements:

.1 Any surcharging of upstream sewer(s) shall not create any upstream problems such as property flooding or impeded mainline flow or impeded service flow.

.2 Flows shall be transported through a closed, leak tight pipeline or other method as approved by the Owner to the nearest or most economical disposal area.

.3 On all liner installation time periods, the Contractor must maintain on site both a primary and stand-by by-pass pump and pump power supply as required to ensure sufficient flow control. The stand-by by-pass pump and power supply shall be of an equal or better capability than the primary by-pass pump and power supply. No by-pass pumps or related equipment shall be disconnected or removed from the sewer or job site until after all service connections have been reinstated, all by-pass equipment has been flushed/cleaned as approved by the Owner, and the Contractor has recorded the V3 CCTV inspection.

.4 All by-pass pumping shall be in place and operational prior to the final pre-installation inspection.

.5 All by-pass pumps and related equipment must be silenced equipment or contained within an acceptable sound reduction structure.

.6 Flow Control for Service Connections on the Sewer Being Lined

.1 When service connection flow control is employed, the Contractor shall meet the following requirements:

.1 When private service back-up is used, advise building occupants of out-of service date and duration. Provide building occupants with instructions to limit water use.

.2 When private service back-up is used, the maximum out of service time shall be 8 hours.

.3 Make provisions to provide for residential bypassing as well as building bypassing of multi-unit residential, commercial, and industrial buildings (as determined by the Owner) from a clean out or property MH to maintain sanitary and storm sewage services to the property if required.

.4 Make all necessary arrangements with the owners of each residence and/or building. The Contractor shall contact all property owners and/or tenants to co-ordinate the repair work to the sewer and minimize any impact on residents and/or businesses.

.7 Event of Loss of Redundant Capacity

.1 When circumstances arise requiring the use of redundant capacity and therefore redundant capacity no longer exists, action shall be undertaken immediately to restore the lost capacity to full function so that redundant capacity is fully restored. If redundant capacity cannot be restored, only critical work already in progress that must be completed (such as lining inversion, curing and liner end opening) shall proceed and without delay. No other work continuation (such as CCTV inspection) shall take place without a fully functional redundant capacity.

.2 When it is known or suspected that redundant capacity is not or may not be fully functional, no work shall be started that requires bypass operation.




Section 33 11 05

Page 24 May 2019

.8 Bypass Coordination and Supervision

.1 A Bypass Supervisor shall be assigned to manage all bypass pumping operations. The Owner shall be advised of this person and be provided with 24 hr contact information. When the bypass is required to operate, the supervisor shall assure that the bypass system is in full function operation, including fully available 100% redundancy before any work is started for which the bypass is required. When the bypass is in operation, the bypass supervisor will assure that there is continuous presence by a competent person to watch over the bypass including manual checking of upstream levels, pump fuel levels and other indications of potential trouble such as at pump suctions and discharges, discharge conduits and redundancy availability.

.9 Responsibility for Leaks, Spills and Back-ups

Section 33 11 05

Page 25 May 2019

.2 The CCTV camera equipment shall be of a self-propelled type with colour pan, tilt and zoom camera or equivalent capability with a range of at least 200 m from the insertion location. The minimum resolution shall be 400 lines on the live picture and at least 250 lines on any recording. The camera equipment shall be capable of correctly focusing on locations being viewed and shall be equipped with adjustable focusing capability. The camera equipment shall be suitable for the size of the sewer. The picture on the CCTV monitor shall be an accurate representation of the inspection and shall have no on screen distortion such as vertical flattening or horizontal widening.

.3 The camera shall be located closely in the center of the pipe and shall provide a picture that properly and fully shows the full circumference of the pipe in sufficient detail to verify the interior details and features of the existing sewer or lined sewer meet with requirements (Cleaning and Preparation requirements, CIPP liner requirements and service connection reinstatement requirements). The camera equipment shall be provided with sufficient lighting of the viewing zone so that all details and features can be seen clearly and are not obscured by insufficient lighting or shadows both on the perimeter of the picture and in the direction of the view down the pipe. CCTV inspections with insufficient lighting will not be accepted.

.4 The view shall not be obscured by any vapour in the pipe. Where steam or other vapour obscures or otherwise interferes with the view, the Contractor shall take necessary action required to eliminate steam or vapour that interferes with the view.

.5 Where and when required for CCTV inspection, the pipe shall be sufficiently free of flow or standing water so that all surfaces can be fully inspected without any areas or features being obscured by water in the pipe. This will require flow control of flow during post cleaning and preparation CCTV inspection, CCTV monitored service connection reinstatement and final CCTV inspection of the completed CIPP liner.

.6 The speed of inspection shall allow for proper viewing and inspection and shall not exceed 10 m per minute subject to requirements for pausing at service connections or other features, or as may be required by the Owner for specific situations.




Section 33 11 05

Page 26 May 2019

.7 CCTV inspections shall be recorded on flash drive in a non-proprietary format compatible with Halifax Water’s CCTV viewing equipment and software. Each flash drive shall be clearly marked as to contents and date. One copy of each flash drive shall be provided to the Owner.

.8 The initial screen of any inspection shall record the inspection date, Contractor name, Contract identification information, location of the inspection, MH-MH section number(s), start and end MH numbers and the inspection type (e.g. Post Cleaning and Preparation, Final Inspection after Lining) and any other information routinely required for sewer CCTV inspections. The distance counter meters shall be zeroed at the starting MH and run continuously throughout the inspection. The section number shall appear continuously along with the distance count.

.9 At each service connection, the camera shall view the entire opening and up the service connection pipe (pan and tilting as required) for a minimum of 10 seconds or longer as necessary to view and record the complete details of the service connection.

.10 A computer generated written report shall accompany the CCTV inspections detailing features (e.g. service connections etc.) and their locations (distance from starting MH). The location information shall include the clock position.

.11 CCTV vehicle shall have sufficient space to accommodate the Owner for live viewing as well as the CCTV operator.

.2 Digital Video Files of the CCTV Inspection

.1 The compression or other technology used in making digital representation of the CCTV image shall not reduce the useable clarity of the image and shall not result in visible pixels on the computer screen when viewing the CCTV inspection in actual size (not full screen size). The digital format shall be MPEG-2 (Moving Pictures Expert Group - 2 and ISO/IEC 13818) standard or equivalent. The digital format shall not make computer playback dependent on a particular computer operating system or specific video player for full function playback. The digital recording shall play with full function in:

Windows Media Player Windows,

QuickTime Player Windows,




Section 33 11 05

Page 27 May 2019

QuickTime Player Mac,

VLC Player Windows

.2 Where these video players are properly configured for the MPEG-2 format. Video recordings that will not play back properly in all the above players will not be accepted and will require re-doing the CCTV inspection (or other corrective procedure).

3.3 PRELIMINARY CCTV INSPECTION – V1

.1 The Contractor shall make a preliminary CCTV inspection (called the V1) of the sewer section before undertaking any work required for the CIPP lining of the section. The purpose of the V1 is to determine and record the initial condition of the sewer section and to determine if a significant changed condition exists versus the CCTV inspection provided to the Contractor by the Owner. Significant changed condition means a condition that will prevent lining of the section, require an unexpected excavated repair before lining, require a change in the liner design resulting in an increased liner thickness to deal with the changed condition or any other situation, which in the Owner’s opinion, is a significant changed condition.

.2 Where a significant changed condition is encountered, the Contractor shall immediately inform the Owner.

.3 In making the V1, the Contractor shall employ only such preliminary cleaning that is necessary to obtain a CCTV inspection sufficient to record the initial condition including a count and condition of service connections.

.4 De-watering of the sewer shall be sufficient for V1 inspection purposes and bypassing of the sewer flow shall be done where the sewer is not sufficiently clear for V1 inspection purposes.

.5 Sewer defect coding is not required for the V1.

.6 The V1 CCTV inspections shall be submitted to the Owner in accordance with the requirements of this standard

3.4 FILLING OF VOIDS

.1 Void Definition

.1 A void is a volume of space starting at the outside wall surface of the existing sewer where there is an absence of soil or ground material. Depending on its size and geometry the void may represent a structural weakness in the pipe/soil system that may continue after lining of the sewer. A void will often by evidenced by missing sewer pipe wall that has allowed the ground material to escape into the sewer, exacerbated by ground water infiltration. Where a void is deemed to create a significant structural weakness in the lined pipe, the void requires filling to re-establish the soil/ground support around the sewer.

.2 Voids Identified for Filling in the Contract

.1 The Contractor shall fill voids as specified for filling in the Proposal documents. Void filling shall ensure structural integrity of the lined sewer and prevent bridging by the liner. The Contractor shall submit for the approval of the Owner a detailed method statement outlining the procedures and materials to be used in filling the voids. The method statement shall correspond with requirements that may be specified for void filling in the Proposal document.

.3 Voids Requiring Filling Not Identified in the Contract

.1 If, during the course of the work (such as during the V1 or cleaning and preparation), the Contactor identifies voids that require filling to ensure the structural integrity of the liner and to prevent bridging by the liner, the Contractor shall advise the Owner of these voids. Where the filling of such voids is required by the Owner, the Contractor shall submit a detailed method statement outlining the procedures and materials to be used in filling the voids. Where the Owner requires filling of the voids, the cost shall be negotiated. However, this provision shall not apply to any voids created as a result of the Contractor’s work unless, and at the discretion of the Owner, the creation of such voids was an unavoidable repercussion of the work.

3.5 CLEANING AND PREPARATION OF EXISTING SEWERS FOR CIPP LINING

.1 General

.1 The sewer sections to be lined shall be cleaned and prepared to meet the requirements for lining including as follows.

.2 Precaution for Cleaning and Preparation

.1 The contractor shall take all reasonable steps to prevent the collapse or irreparable damage to the pipe wall (which would create the need for an open cut repair prior to lining) during the cleaning and preparation of the sewer sections. Should the contractor identify areas within the sewer sections which present a high risk for this situation to occur during cleaning and preparation, they shall notify the Owner and present their recommended approach to avoid the potential collapse or damage.

.2 The sewer sections to be CIPP lined shall be cleaned and prepared to meet the requirements for lining including as follows.

.3 Soft Deposits and Loose Debris

.1 All soft deposits shall be removed by suitable cleaning methods such as water jet sewer cleaning sized and rated for the sewer being cleaned. Soft deposits include such deposits as slime, grease and soft corrosion products. Loose debris includes such as soil, sand and contents of the sewer flow that have settled out of the flow.

.4 Corrosion Soft Deposits

.1 If the sewer is experiencing signs of corrosion, it may have areas of corrosion soft deposits. The severity of this corrosion and the type and depth of the corrosion products layers vary at different locations in the sewer sections. Where the depth of this layer is such that cleaning will cause exposure of the reinforcing steel (or where it is already exposed), the cleaning process shall be checked by CCTV to gauge the degree of removal and penetration into the pipe wall from the cleaning process.




Section 33 11 05

Page 30 May 2019

.2 Where CCTV checking of the cleaning process indicates that full removal of soft corrosion layers is resulting in or may result in under-cutting of the reinforcing steel, soft layer removal operations shall be limited to not deeper than the outer surface of the reinforcing steel. The Contractor shall advise the Owner when cleaning and preparation operations in corroded sewers are creating, or will create a situation where it is advisable to scale back or halt such operations. On such advice, the Owner will advise the Contractor regarding the necessity for further cleaning and preparation.

.5 Hard Deposits

.1 Hard deposits, such as hard calcite shall be removed if they result in a diametric reduction of the sewer exceeding 15 mm. No hard deposits shall remain in place with sharp or ragged edges that will cause sharp indentations into the liner regardless of the diametric condition.

.2 Hard deposits shall be removed using suitable equipment such as flailing or robotic cutting/grinding. The method of removal shall be such that no damage is caused to the pipe that will compromise the long-term structural performance of the rehabilitation.

.6 Tree Roots

.1 Any tree roots protruding into the inside of the pipe shall be sufficiently removed so that they do not interfere with the CIPP lining installation and the finished liner.

.7 Protruding Service Connections

.1 Any service connection to the sewer that protrudes into the inside of the sewer shall be trimmed back if the protrusion exceeds 12 mm. Regardless of the protrusion length, any sharp or ragged edged protrusions shall be trimmed smooth. Trimming shall be done with a method that does not damage either the service connection pipe or the mainline pipe. Robotic cutting is an acceptable method. Flailing with knocking devices is not an acceptable method.

.4 All measurements for the location of service connections will be obtained from a steel tape measure and will be taken from a convenient, fixed and permanent reference point.

.5 The SCR shall be provided to the Owner.

3.7 POST CLEANING AND PREPARATION CCTV INSPECTION – V2.

.1 After completion of the cleaning and preparation of the sewer section (including all reaming, cutting, grinding and void filling) of the sewer section, a CCTV inspection (called the V2) of the full length of the sewer section shall be done. The V2 shall be done in accordance with the requirements of this standard.

.2 Flows for V2 shall be at a level that allows for visual confirmation that the preparation work was completed adequately.


.4 The V2 complete with all reports shall be provided to the Owner at least 48 hours prior to lining for the Owner’s approval of the cleaning and preparation.

.5 On its discretion, the Owner may waive the requirement for the V2 to be submitted for approval 48 hours prior to lining, such as when approval for lining was provided at a live viewing of the V2 by a Halifax Water representative. However, in such cases the V2 submission shall always be submitted at a later time.

.6 Lining shall not commence until acceptance of the cleaning and preparation has been provided by the Owner to the Contractor.

.7 In the event that, after the V2, a deficiency in the cleaning and preparation is identified that requires correction, the V2 shall be redone after the correction has been done and the redone V2 submitted to the Owner.




Section 33 11 05

Page 33 May 2019

.8 At the completion of cleaning and preparation for all sections, the CCTV inspections shall be consolidated on to one USB flash drive (or more than one as needed) and shall be in sequential order from upstream to downstream starting with the most upstream section. A USB flash drive shall also be provided to the Owner.

3.8 CIPP LINER – TYPE AND MATERIAL

.1 The CIPP lining shall be in accordance with and meet the requirements of referenced standards or the properties used in the liner designs, whichever are higher. (Designs shall not use properties lower than those in the reference standards).

.2 The CIPP liner to be installed by the Contractor shall have a substantial history of successful application in similar size sewers. This history of application shall include: installations throughout Canada in sanitary sewers, storm sewers, and culverts; include all sizes required in the work for this contract. Prior to award of contract, the Owner will request the history of use and assess whether the proposed CIPP liner meets requirements for approval.

.3 Materials shall be in accordance with the requirements of ASTM D5813-04(2008) and ASTM F1216-16, ASTM F1743 and ASTM F2019 as applicable to the type of CIPP liner used.

.4 Where reinforced CIPP liners are used, they shall be in accordance with ASTM F2019-03(2009) and where applicable with ASTM D5813-04(2008) and ASTM F1216-16.

.5 The quantity of resin used in the liners and its impregnation shall meet with the requirements of ASTM F1216-16, section 7.2.

.6 Where, in the course of work, the Contractor has reason to use materials that differ from the original materials proposed for this contract the Contractor shall make a written request to the Owner detailing the proposed changes and reasons for the requested change. Any proposed different materials shall meet the above standards (as applicable to the type of liner) and require the written approval of the Owner prior to substitution.

.7 Where, in the opinion of and at the sole discretion of the Owner, confirmation of use of the proper material is required, appropriate procedures such as an IR scan (Infrared Spectroscopy) for resin may be used. If required, a baseline IR scan of the resin to be used on this contract shall be provided to the Owner. The baseline IR scan shall be made on the resin after catalyst addition and before any curing.

3.9 CIPP LINING – STEAM CURING

.1 In addition to temperature sensors being placed at the upstream and downstream MHs during the curing of the CIPP liner, steam curing of CIPP liners shall include a monitoring system capable of recording temperatures along the entire length of the CIPP installation to verify proper curing temperatures. Temperature sensors shall be placed between the host pipe and the liner within the invert (bottom) of the host pipe throughout the full length of the liner installation. The system shall be capable of recording the temperature at the invert throughout the entire length of the installation. The sensors shall be spaced apart at intervals no greater than 5 meters for pipe sizes up to 375 mm in diameter; and no greater than 3 meters for pipe sizes 450 mm and larger. Additionally, sensors shall be strategically placed at points where a significant heat sink is likely to be anticipated (e.g. sag in the host pipe, active infiltration, etc.). The monitoring and recording of these sensors shall be by a small computer which can record the temperatures throughout the processing of the CIPP and be available for viewing on site by the Owner during the cure process. Upon completion of the liner installation, the temperature data shall be submitted to the Owner as part of the overall final QA/QC submittal requirement.

.2 Acceptable temperature sensor monitoring systems include:

ZIA Systems (www.ziasystems.com/) or

Owner approved equivalent.

.3 Prior to installing the liner in the host pipe, the temperature monitoring system’s proper functioning shall be confirmed by hooking it up to the computer and ensuring that the sensors are reporting the ambient sewer temperatures. No more than two sensors in sequence can be found faulty during this test. If three or more sensors in sequence are discovered faulty, a new sensor array shall be pulled into the host pipe replacing the previously installed array; and the new array shall be again tested for its proper functioning.

.4 The sensor array’s computer database shall have an output report that identifies each sensor by its station over the length of the CIPP installation. The maximum temperature achieved during the steam cure process and the time sustained at or above the required curing temperature shall be recorded and submitted for each sensor.

Section 33 11 05

Page 36 May 2019

.2 The Contractor may provide CIPP liners with in-place properties greater than the required minimum values above. Increased properties will normally be reflected in decreased liner thickness requirements. CIPP liners installed with physical properties below the minimum required property values shown above will be considered non-compliant, regardless of the any design reconciliation outcome.

.3 The short-term test values of flexural modulus and flexural strength used as the starting values from which the long-term design values are derived shall be values that have been and will be reliably and repeatedly obtained by the Contactor in installations of the same liner material and be substantiated by a history of testing of samples. These short-term test values shall be identified in any liner designs. The retention value to be used in design shall be based on ASTM D2290 (or equivalent as acceptable to the Owner) testing for the liner material that substantiates the derivation of the retention value used.

.4 Also see Section 3.22 on liner samples and testing.

3.11 CIPP LINER DESIGN

.1 General

.1 The wall thickness for CIPP liners shall be determined in accordance with the design method set out in ASTM F1216-07a, Appendix X1 for Fully Deteriorated Gravity Pipe Condition as per Section X1.2.2. The design method in later versions of F1216 is not acceptable.

.2 The thickness determined by design shall be the minimum thickness of the completed CIPP liner in the sewer, subject to design reconciliation of sample test results. Where design reconciliation based on as tested properties is performed by the Owner the minimum structural thickness may increase or decrease.

.3 The Contractor shall provide liner designs for each MH-MH section of lining. The Contractor shall provide Proposal Designs and when required, Special Designs.

.4 A Special Design is required during the work if and where a Proposal Design is found to be unsuitable for the field verified conditions based on the Contractor’s Evaluation of MH-MH lining sections.

CIPP Liner

Flexural Modulus Used for Design

The value of flexural modulus used for design shall take into account the expected long-term creep behaviour of the CIPP liner so that the use of the design value in the design formula(s) will yield a liner thickness that will perform as required for the design life. The flexural modulus design value shall be the short-term test flexural modulus reduced by the Creep Retention Factor (CRF) for the liner material. The CRF shall be established by ASTM D2990 (or equivalent) long-term testing. The short-term test flexural modulus used as the starting value before reduction shall be the value that will be reliably and repeatedly achieved in short-term testing of installation samples of the same liner material. The CRF shall be derived from long-term testing and be appropriate for stress and stress duration in the installed liner. Independent third party test data shall be available to substantiate the short-term test and CRF values used in design. Liner designs shall identify the short-term test value, the CRF and the long-term design values. If these values are not clearly identified the designs shall be rejected by the Owner.

.4 General Requirements for Designs

.1 Design Certification and Clarity

.2 All designs shall be approved and stamped by a professional engineer licensed and authorized in the Province of Nova Scotia.

.3 All designs shall provide sufficient detail and clarity to allow for straightforward identification of the liner location (when for specific location) and design parameters used in the design. The design shall clearly identify whether it is a Proposal Design or a Special Design.

.4 Designs that are confusing or fail to properly identify the required design parameters will not be accepted.

.5 Design Thickness is the Minimum Required Finished In Place Structural Thickness.

.6 The CIPP liner wall thickness determined by design shall be the in place, completed liner thickness. Liner thickness measurements, either from samples or in ground, shall be compared to the design thickness for acceptance. Acceptance of final liner thickness shall be subject to reconciliation of actual required thickness based on tested liner properties. Where tested liner properties are different from the properties assumed in the liner design, the required thickness shall be determined by design reconciliation. Such reconciliation may change the required thickness for the final completed liner based on as tested properties. However in no case shall the required thickness be based on properties that are less than the minimum required properties or result in a required thickness that is less than the minimum thickness specified in the specification.

.7 Liner wall thickness measurements and determination of the actual effective thickness shall be in accordance with ASTM D5813-04(2008). Measurements of the actual installed liner wall thickness shall not include the thickness of any non-structural components.

.5 Short-term Flexural Modulus and Short-term Flexural Strength

.1 The short-term values of flexural modulus and flexural strength (as per D790) used as the starting values from which the long-term design values are derived shall be values that will be reliably and repeatedly obtained in the installed liners as substantiated by testing samples from installed liners. These short-term values shall be identified in the liner design.




Section 33 11 05

Page 43 May 2019

.6 Substantiation of Liner Physical Properties Used for Design

.1 It is the responsibility of the Contractor to obtain third party testing of the CIPP liner sufficient to substantiate the liner material properties used in design. Once a liner installation has been completed, the Contractor shall provide the substantiated test results and other information to the Owner for review and approval within ten (10) business days of the liner installation (i.e. date sample is signed by the Owner).

.2 Substantiation, at a minimum, will include ongoing third party testing results for short-term properties of flexural modulus and flexural strength on installed liners showing that the properties assumed in design are routinely achieved in the field for the same materials being used for this contract. Substantiation must also include the basis for long-term properties including, at a minimum, long-term (10,000 hr) testing on the resin being used for flexural strength and flexural modulus. For reinforced liners, long-term testing must be on the complete liner product itself, not just for the resin element.

Section 33 11 05

Page 48 May 2019

.6 Flow control shall be required as such to ensure a clear view of the installed liner during the V3.

.7 Sewer defect coding is required for the V3.

3.19 INSTALLED CIPP LINER THICKNESS, FIT & FINISH REQUIREMENTS

.1 The finished lining shall fit neatly and tightly to the existing sewer without significant fins or excessive wrinkling. Any annulus gap between the liner and the existing sewer inside surface shall be in accordance with industry standard shrinkage characteristics for properly installed, cured and cooled CIPP. Annulus gap which is due to improper liner sizing, inadequate preparation of the existing sewer, improper installation, curing or cooling, or the effect of ground water pressure will not be accepted.

.2 The liner shall extend continuously from MH to MH starting and ending at the inside walls of the MH (except where lining is made through intermediate MHs).

.3 The completed installed liners shall conform to the following requirements.

Continuity of Liner

The finished liner shall be continuous over the entire length of the liner installation from MH to MH without any breaks, separations or joints.

Liner Fit to Existing Sewer Liner

The outside surface of the finished liner shall be in contact with the inside surface of the existing sewer subject to the contact tolerance. The inside surface of the existing sewer is the surface after the sewer has been cleaned and prepared for lining in accordance with the cleaning and preparation requirements. The contact tolerance is 1.0 mm. Where any space of gap between the outside surface of the liner and the inside surface of the existing sewer line exceeds 1.0 mm, the liner fit will be deficient, subject to exceptions noted below.

The liner should also be able to negotiate vertical/horizontal elbows and bends with various degrees (angles ranging from 0 to 45 degrees).

Exception to Liner Fit at Existing Sewer Line Irregularities

Existing sewer line irregularities include off set joints, protrusions, bumps or other similar situations in the existing sewer that remain after the sewer has been prepared in accordance with the cleaning and preparation requirements. Neither ovalisation of the existing sewer nor curves made by joint deflection are irregularities in this context. Where an irregularity exists, The contractor shall inform the Owner prior to lining and an exception to the liner contact tolerance requirements will be allowed in the irregularity zone. The irregularity zone is defined as a zone extending a distance of up to ¼ of the liner inside diameter in




Section 33 11 05

Page 49 May 2019

any direction from the irregularity as measured along the inside surface of the liner.

A liner fit exception at an existing sewer irregularity shall not present an obstruction to sewage flow whether or not it complies with the allowed exceptions.

Liner Shape

The liner shape will be as defined by liner fit to existing sewer line. In general the liner shape shall conform to the shape of the existing sewer line inside surface after its cleaning and preparation in accordance with requirements. However, where the existing sewer line shape is not defined (missing pieces of sewer line) the liner may either bridge the missing wall section or indent into the missing wall section. Where the liner bridges, the shape of the liner shall match the shape of adjacent sewer line and the inside diameter of the liner shall be as required for Contact Tolerance for the adjacent sewer line. Where the liner indents, the depth of the indent shall not reduce the liner wall thickness below the Wall Thickness Tolerance.

Liner Wall

The liner wall shall be free of any interior bulges, ribs, ripples, folds or other irregularities except where these irregularities comply with the Liner Wall Thickness Tolerance, fit, shape and wall thickness given above. The wall of the liner shall be free of any voids (dry spots), cavities or bubbles.

Liner Terminations

At manhole entrances and exits the interface between the exterior surface of the liner and the manhole shall be watertight to the requirements for external hydrostatic pressure. The finished ends of the liner shall be neat and smoothly cut. The benching in the manholes shall be modified where required to conform to liner dimensions.

The liner shall extend into each MH a minimum of 12 mm (½”) and a maximum of 25 mm (1”), such that the MH liner material application can be applied to the back (outer surface) of the liner, creating a seal around the CIPP liner, pipe and MH interface.

Bulges, including Lifts and Sags

There shall be no bulges in the liner that are not consistent with the surface profile of the existing sewer before lining. Such bulges will be considered an indication of a major structural deficiency in the liner and will require major remedial action to the satisfaction of the Owner. Where bulges are suspected or proven to contain internal separations within the wall of the liner, remedial action up to and including removal and replacement of the liner will be required. This applies to bulges that may be called lifts or sags.




Section 33 11 05

Page 50 May 2019

3.20 LINER WALL THICKNESS AND TOLERANCE

.1 General

.1 The liner's finished structural wall thickness shall be as specified in the applicable liner design approved by the Owner. The required structural wall thickness may also be determined by a design reconciliation using test properties done by the Owner.

.2 The effective liner wall thickness shall be determined in accordance with ASTM D5813-04(2008).

.3 The wall thickness tolerance is:

Minus 0%

Plus 25%.

.4 The wall thickness under consideration is the final cured-in-place thickness and shall not include any layers or material that does not contribute to the structural rating of the liner.

.2 Liner Thickness

.1 Finished liner thickness shall be no less than the design thickness or specified minimum thickness, whichever is greater. Thickness shall be determined in accordance with the provisions of ASTM D5813-04 (2008). The effective thickness of the liner shall be either the average thickness or the minimum thickness multiplied by 0.875, whichever is less.

.2 Required liner thickness shall be subject to design reconciliation based on CIPP properties determined in as installed liner sample testing. Such design reconciliation may require a different liner thickness (versus the original design thickness) to correspond with design based on as installed sample tested properties. In no case shall a design reconciliation result in a required liner thickness that is less than the specified minimum thickness.

3.21 INSTALLED CIPP LINER PHYSICAL PROPERTIES REQUIREMENTS

.1 The complete installed liner shall have the following required physical properties:

.1 Short-term Test Flexural Modulus: Shall meet or exceed the value used in the applicable liner design




Section 33 11 05

Page 51 May 2019

.2 Flexural Strength: Shall meet or exceed the value used in the applicable liner design

.2 In the case of long-term design values of flexural modulus and flexural strength used in design, the liner shall possess the required long-term retention characteristics such that the long-term values used in design will be met by the liner over its design life.

3.22 SAMPLES AND TESTING OF INSTALLED CIPP LINER

.1 General

.1 The Contractor shall provide and have tested samples of the liner installations at the sampling rate indicated below. The testing shall be done at an independent testing agency experienced in testing CIPP samples and approved by the Owner.

.2 Testing will determine the short-term test flexural strength, the short-term test flexural modulus, structural thickness and any other relevant properties of the cured liner as represented by the samples. Test results must meet the values of short-term test flexural modulus and flexural strength used in the applicable liner design provided by the Contractor and the thickness determined by that design.

.3 Unless otherwise approved by the Owner, one sample per continuous liner installation is required to be collected and tested. Each sample must be identified, dated and signed by the Owner prior to leaving the project site. Payment for samples will be made per the payment item.

.4 Samples shall be delivered to the independent testing agency designated below in a timely manner, such that test results are provided to the Owner within 10 business days after liner installation. Should samples not be submitted; the Owner, at their discretion, may issue a suspension of work order for CIPP lining until such time that the test reports are submitted.

.5 Testing Agency to be Used: Paragon Systems, Concord, Ontario. 905-738-0447

.2 Type of Samples




Section 33 11 05

Page 52 May 2019

.1 CIPP liner samples shall be restrained formed cylindrical pipe type samples. The Owner will not accept plate type samples unless the Contractor can demonstrate to the satisfaction of the Owner that a restrained pipe samples cannot be done for a specific installation. Plate type samples will only be considered for sewer sizes greater than nominal 525 mm. In instances, as approved by the Owner, where plate type samples are accepted, a derate percentage of 15% and 18% will be respectively applied to the flexural modulus and flexural strength values obtained from the sample test result(s), in accordance with the North American Society for Trenchless Technology (NASTT’S) Cured-In-Place Pipe (CIPP) Good Practices Guideline First Edition. The derated flexural modulus and flexural strength values will be used to verify the Contractor’s compliance with the contract specifications. Refer to ASTM F1216-16 for further information on sampling methodology.

.2 Restrained cylindrical pipe type samples shall be made by inserting the liner through a form with an inside diameter as close as possible to the inside diameter of the sewer being lined. The samples shall be taken at the end MH or an intermediate MH. The length of the form shall be sufficient to prevent edge effects on the sample coupons cut from the sample and provide the sufficient length of good sample as required for test coupons. The form shall be sufficiently strong to prevent the form expanding during liner installation and processing. In making the sample the Contractor shall use heat containment provisions, such as felt insulation with sandbags over and around the sample, so that the thermal environment during the sample cure is similar to the thermal environment within the sewer during the liner cure. For large size sewers the form can be a multi-piece form assembled within the MH.

.3 Sample Length

.1 The length and size of any sample shall be sufficient to obtain at least 5 test specimens for ASTM D790 testing.

.2 The sample from which the test specimens are cut shall be sufficiently large so that sample edge effects can be eliminated from the test specimens. Sample size shall allow test specimen length of 16 times liner thickness for non-reinforced CIPP and 32 times thickness for reinforced CIPP plus at least 100 mm additional sample length to eliminate edge effects. For example a sample for a 300 mm by 6 mm thick non-reinforced liner shall be at least 16 x 6 = 96 mm + 100 mm = 196 mm long.

.5 Testing of Cured Liner Samples

.1 The Contractor shall provide for testing of samples of cured liner at an independent testing agency. The testing agency shall be subject to the approval of the Owner. The Contractor shall authorize the testing agency to forward the test reports directly to the Owner and communicate with the Owner concerning the testing and results. Samples shall be tested for flexural modulus and flexural strength as per ASTM D790 and thickness as per ASTM D5813-04(2008). The provision of testing service shall allow for the obtaining of test reports within 10 days of delivery of the sample to the testing agency.

.2 Delamination testing may also be performed in accordance with ASTM F-1216 specifications, at the Owner’s discretion.




Section 33 11 05

.6 Design Reconciliation for Sample Test Results




Section 33 11 05

Page 55 May 2019

.1 Where the test results do not meet or exceed the required physical properties, the liner shall be deemed deficient subject to design reconciliation of the test results.

.2 A liner deemed deficient based on sample test results shall be reconciled for true deficiency by repeating the design for the liner using the test results for flexural modulus and flexural strength while keeping all other design parameters the same.

.3 Where the repeated design (the reconciliation) shows that the combination of test results (flexural modulus, flexural strength and thickness) provides a liner that meets the reconciled design requirements, the liner shall not be deemed deficient.

.4 Such design reconciliation shall not be permitted when test results do not meet the minimum requirements for flexural modulus and flexural strength in the ASTM F1216 in which case the liner will be deficient.

.5 In no case shall design reconciliation yield a required liner thickness that is less than the specified minimum thickness.

.6 The Owner shall make or otherwise approve any design reconciliation. Two examples of design reconciliations are shown below.

.7 Reconciliation Example #1 (Restrained Sample)

.1 For a 450 mm installation the required liner thickness is 7.6 mm designed at flexural modulus of 2413 MPa and flexural strength of 31 MPa. Tested results show thickness is 7.2 mm, flexural modulus is 2995 MPa and flexural strength is 38.9 MPa. There is an apparent deficiency in liner thickness. Reconciliation of apparent deficiency is shown below.

Section 33 11 05

Page 57 May 2019

.2 In this example the reconciliation shows that the as tested thickness of 7.2 mm is sufficient when the tested properties are taken into account. Therefore, the liner would not be deficient based on test thickness.

.8 Reconciliation Example #2 (Plate Sample)

.1 For a 600 mm installation, the required liner thickness is 9.6 mm designed at flexural modulus of 2758 MPa and flexural strength of 31 MPa. Tested results show flexural modulus is 2465 MPa and flexural strength is 35.6 MPa. Due to this being a plate sample a derate percentage of 15% and 18% is respectively applied to the flexural modulus and flexural strength values obtained from the sample test results. These derated values are used to determine specification compliance. Derated test results for flexural modulus and flexural strength values are 2095 MPa and 29.2 MPa respectively. The field determined thickness of the liner is 10 mm. There is an apparent deficiency in flexural modulus and flexural strength. Reconciliation of apparent deficiency is shown below.

Flexural Modulus and Flexural Strength remain deficient based on derated test result properties




Section 33 11 05

Page 59 May 2019

.2 In this example the reconciliation shows that the as tested thickness of 10 mm is not sufficient when the tested properties are taken into account. Therefore, the liner is deficient based on test properties.

.3 In the case where samples test results may not meet requirements in thickness, flexural strength or flexural modulus, the Owner may choose to confirm the test results using options such as testing of another sample (to be cut from the liner by the Contractor), measuring of in-place liner thickness at the MHs to confirm thickness results. Where in Halifax Water’s opinion the test results and any further investigation as above indicate that the installed liner is not compliant, the Contractor shall take remedial action acceptable to the Owner without cost to Halifax Water.

3.23 LINER DEFICIENCIES AND REMEDIAL MEASURES

.1 General

.1 When the Contractor is aware of any deficiencies in the work or in the results of the work, the Contractor shall advise the Owner of these deficiencies within 48 hours including situations where the deficiency has already been rectified.

.2 Where a liner is deficient, the Contractor shall rectify the deficiency(s) with a remedial method that is acceptable to the Owner. Where there is no remedial method acceptable to the Owner, the liner shall be removed and replaced at no cost to Halifax Water.

.3 The specific deficiencies addressed below are examples and do not represent all the deficiencies that may occur.

.2 Thickness Less than Required Thickness:

.1 Refer Section 3.11 3.11 .4.

.3 Physical Properties Less than Required Properties

.1 Refer Section 3.10 .

Section 33 11 05

Page 60 May 2019

.1 The finished pipe shall be continuous over the entire length of a new installation and shall be free of dry spots, lifts and delamination. If these or other conditions, which are not in compliance with this specification, are present, the Contractor shall repair the defects at their own cost, to the Owner’s satisfaction. In the event the CIPP does not fit tightly against the host pipe at its terminal points, the space between the pipes shall be sealed with a resin mixture compatible with CIPP.

.5 Excessive Fining or Wrinkling

.1 Excessive liner material shall be removed to the acceptance of the Owner. Where excessive material cannot be removed without compromising the structural integrity of the liner, the Contractor shall take other remedial action as acceptable to the Owner.

.6 Bulges, Lifts and Sags

.1 There shall be no bulges in the liner that are not consistent with the surface profile of the existing sewer before lining. Such bulges will be considered an indication of a major structural deficiency in the liner and will require major remedial action. Where bulges are suspected or proven to contain internal separations within the wall of the liner, remedial action up to and including removal and replacement of the liner will be required. This applies to bulges that are may be called lifts or sags.

.7 Remedial Action

.1 Where deficiencies are identified, the Contractor shall perform the accepted remedial action in a timely manner without unreasonable delay.

.2 Where a deficiency will seriously impact sewer or service connection flow capacity and are considered likely to cause sewer back-ups onto properties or other overflows, the Contractor shall take immediate action to prevent such problems without waiting for acceptance of remedial method from the Owner. In such case, the final resolution of a deficiency, if required, shall be by a method acceptable to the Owner.




Section 33 11 05

Page 61 May 2019

.3 The contractor shall provide the Owner with a list of all the identified deficiencies prior to any remedial action. The list shall include the location of the deficiency and the remedial action required to rectify the deficiency, along with the associated CCTV video inspection.

.4 The cost of any work to rectify a deficiency is the responsibility of the Contractor.

3.24 WARRANTY

.2 This clause applies to all sewers (storm, sanitary and combined) to be lined.

PART 2 - PRODUCTS

2.1 SEWER SIZES – NOMINAL VERSUS ACTUAL

.1 The Contract Documents generally refer to nominal sizes for sewers and not the actual inside diameter sizes. The actual inside diameters will typically be slightly different than the nominal value. It is the Contractor’s responsibility to use the sewer size dimensions that are appropriate and proper for rehabilitation purposes including UV CIPP liner design.

2.2 SEWER SIZE INSIDE DIAMETER TOLERANCES

.1 General

.1 Sewer sizes shown in proposal and contract documents are nominal metric sizes. For the purpose of the contract, a nominal sewer size shall include actual sizes within the range shown below.

Nominal Size (mm)


(mm)


(mm)

200 > 178 ≤ 216

225 > 216 ≤ 241

250 > 241 ≤ 279

300 > 279 ≤ 343

375 > 343 ≤ 419

450 > 419 ≤ 483

500 > 483 ≤ 521

525 > 521 ≤ 572

600 > 572 ≤ 648

1200 > 1181 ≤ 1295



PIPE – MAINLINE

Section 33 11 10

Page 14 April 2019

.2 Where the inside diameter fits within the range for a nominal size, the sewer shall be deemed to be that nominal size for payment purposes. For example, a sewer identified in as a 900 mm that has an actual inside diameter up to 953 mm shall be deemed to be a 900 mm sewer. Whereas a sewer identified in the contract documents as a 900 mm that has an actual inside diameter above 953 mm shall be deemed to be a 975 mm sewer.

.3 The applicable sewer size for payment shall be based on the inside diameter that has been determined, by measurement, to be the diameter to be used for sizing the UV CIPP liner.

.2 Sewer Size for Lining Increased by H2S Corrosion

.1 The sewer sections for rehabilitation by CIPP lining may be internally corroded by H2S induced corrosion. In some sections the corrosion is severe with exposed reinforcing steel. Some sections have exposed gaskets. In determining the inside diameter of the sewer for sizing of the liner, the Contractor shall take into account that most, if not all H2S corroded sections will have enlarged inside diameters, especially after cleaning and preparation. Refer to Section 2.4 on measurement.

2.3 OBJECTIVES FOR UV CIPP LINING

.1 The objectives, over the design life of lining, for the UV CIPP lining of sewers are to prevent further structural deterioration, prevent corrosion, prevent root intrusion, prevent/reduce infiltration, prevent offset joints and improve flow characteristics for the sewer.

.2 UV CIPP Lining shall be a tight fit to the inside of the existing sewer and conform closely to the shape of the existing sewer without bridging, gaps, or voids.

.3 UV CIPP lining shall be installed without excavation by installation into existing pipelines through MH access. Exception shall be made when existing MH access is of insufficient size or existing MH location is inadequate.



PIPE – MAINLINE

Section 33 11 10

Page 15 April 2019

.4 UV CIPP liners shall be designed in accordance with the Design Section of this specification.

.5 The term liner means a continuous reach of lining extending over the section to be lined, beginning and ending at manhole inside walls.

.6 The short-term objectives for using UV CIPP lining are to prevent any significant escape of styrene from the liner into or out of the sewer being lined and to prevent any significant styrene odour issues at any locations.

2.4 CIPP LINER SIZING

.1 General

.1 It is the responsibility of the Contractor to obtain and confirm the necessary lengths and interior dimensions of the sewers to be lined and obtain the appropriate measurements. Size information provided on the drawings or in the proposal documents are typically nominal sizes and are not necessarily the correct sizes.

.2 The Contractor’s method for obtaining and confirming sizes shall, at a minimum, include measuring the inside diameter of the existing sewer at all manholes (MHs) in the section. Measurement method shall take into account the possibility that the exposed sewer end is a bell and does not represent the inside diameter of the sewer pipe itself. Measurement methods shall take into account any debris, encrustation, or other build up in the sewer that could result in an incorrect sizing measurement. The contractor shall also take into account any change in pipe characteristics such as offset joints, change in ovality, partial collapse, broken pipe, etc., which could result in incorrect sizing measurement.

.2 Measurements for Liner Sizing

.1 The Contractor is responsible for the correct diametric sizing and length of the UV CIPP liners. The Contractor shall not rely on dimensions provided in the proposal documents including drawings or CCTV inspection.



PIPE – MAINLINE

Section 33 11 10

Page 16 April 2019

.2 The actual inside size(s) of the sewers for lining shall be verified by measurement prior to any fabrication of the liners. The dimensions used for sizing the liner tubes circumference/perimeter shall take into account potential increase in the sewer inside diameter due to the cleaning and preparation of the sewers for lining.

.3 The length of the liner shall be verified by measurement of the section(s) of sewer to be lined. A sufficient length safety margin shall be added to the measured length to assure that the liner extends from begin MH to end MH over the length of the installed liner run.

.4 Measurements shall be provided to the Owner on request.

.3 Liner Sizing Measurements Made Prior to Cleaning and Preparation

.1 Where the sewer inside diameter is measured for sizing the CIPP liner prior to cleaning and preparation, the measurement method shall employ using sizing rods, mandrels or other device that can penetrate through or scrape away any material buildup in order to obtain the inside diameter that is expected to occur after cleaning and preparation of the sewer. Measurements by tape measure shall not be acceptable.

.2 Measurements shall be taken at both ends of all USMH-DSMH sewer sections to be UV CIPP lined.

.3 Where flow control is required to obtain proper measurements, the Contractor shall provide flow control.

.4 Variable Sewer Inside Diameter for Lining



PIPE – MAINLINE

Section 33 11 10

Page 17 April 2019

.1 In the event that an inside diameter variance exists along the sewer section to be lined to the extent that the liner may be oversized or undersized for zones of the lining run, the Contractor shall present the liner sizing situation and anticipated lining results (regarding fit and finish) along with a recommendation for liner sizing for the MH-MH section to the Owner. The Owner shall discuss the situation with the Contractor and in conjunction with the Contractor determine and `approve the sizing of the liner for the installation.

.2 It is understood that in zones of the sewer where a liner may be oversized, there will be excess material in the form of wrinkles and fins in the finished liner. In zones of the sewer where the liner is undersized, the finished liner may stretch out resulting in a decrease in wall thickness. The Owner shall take the foregoing into account in the determination of the approved liner sizing.

.3 The determination of the sewer sizing for lining will consider the best compromise between zones of excess liner material and zones where the liner could be thinned out by stretching or where the stretch may not be sufficient resulting in a liner that is not tight fitting.

.5 Pipe Size for Payment

.1 Payment for CIPP lining shall be based on the nominal size that has a size range that includes the inside diameter after cleaning and preparation. Refer Section 2.2 for size ranges. The inside diameter after cleaning and preparation shall be the dimension used to size the UV CIPP liner for payment purposes.



PIPE – MAINLINE

Section 33 11 10

Page 18 April 2019

.2 For example where the contract identifies the nominal size as 825 mm and the actual inside diameter for lining after cleaning and preparation is within the range shown in Section 2.2 for nominal 825 mm, payment will be made for a nominal 825 mm. However if for a contract nominal 825 mm, the actual inside diameter for lining after cleaning and preparation is greater than the maximum inside diameter for nominal 825 mm shown in Section 2.2 , payment will be made based on the nominal size with a range containing the final inside diameter for lining.

.6 Substantiation for Increase in Nominal Size for Payment

.1 Where an increase in nominal size for payment is warranted, the Contractor shall provide substantiation of the final size for lining that verifies the final size for lining based on measurements of the sewer or other substantiation method that is acceptable to the Owner.

2.5 EVALUATION OF MH-MH SECTIONS FOR LINING

.1 Prior to any liner preparation, the Contractor shall evaluate each MH-MH sewer section to be lined. This evaluation shall determine whether the Proposal Liner Design submitted with the proposal submission yields a liner that is suitable for the MH-MH sewer section being evaluated or whether a Special Liner Design is required.

.2 This evaluation shall also determine whether any excavated repairs are required before lining and whether the sewer section, overall, is a suitable candidate for lining.

.3 The Contractor’s evaluation shall include field assessment and CCTV review assessment for when one or more of the following installation parameters are in exception to the Specific Design parameters.

.4 From the evaluations of all MH-MH sewer sections to be lined, the Contractor shall prepare and maintain a Liner Sections Record (LSR) record of every MH-MH section for lining. The LSR shall show whether the MH-MH section is suitable for a Proposal Design Liner or whether a Special Design Liner is required. When a Special Design Liner is required the LSR shall show the existing sewer parameters that are in exception to the Specific Liner Parameters.

.5 The LSR shall use an Excel spreadsheet to track the Liner Sections Records. The Contractor shall utilize Halifax Water’s MH identification (ID) numbers. When requested, the Contractor shall provide an updated LSR to the Owner.

.6 The LSR shall be constructed in such a way that all MH-MH sections to be lined can be readily identified along with the exceptions to Specific Design Parameters for that section. When a Special Design is made for a MH-MH section the liner design thickness shall be identified in the LSR along with the Special Design parameters.

.7 The format of the LSR shall be as determined by the needs of the Contractor to record and track the evaluation process and the needs of the Owner for use of this data.

2.6 PROPOSAL DESIGN LINER VERSUS SPECIAL DESIGN LINERS

.1 For each sewer section for lining identified in the proposal there will be an approved Proposal Liner Design for each MH-MH section of lining and a fully Where design reconciliation based on as tested properties is performed by Where design reconciliation based on as tested properties is performed by Liner. The Proposal Liner Design shall be submitted by the Contractor with the proposal submission. See Sections 1.6 3.11 .

.2 Where it is determined that a Proposal Design Liner has insufficient thickness for the intended MH-MH section of lining, the Contractor shall provide a Special Design which takes into account the changed parameters that made the Proposal Design Line unsuitable for the location. On the approval of the Owner, the Contractor shall install the Special Design Liner and be paid accordingly.



PIPE – MAINLINE

Section 33 11 10

Page 21 April 2019

.3 The determination of whether a Special Design and correspondingly a Special Design Liner are required shall flow from the Contractors Evaluation of MH-MH Sections for lining work.

2.7 LINER THICKNESS INCREASE

.1 Where a Proposal design thickness liner is insufficient for the installation as determined by a Special Design, the liner thickness to be installed shall be increased to satisfy the Special Design thickness. The thickness increase shall be the minimum required incremental thickness of the liner tube to satisfy the Special Design thickness. Thickness increments shall be as per the Schedule of Quantities and as set forth below.

Increment # Thickness Increment

1 1.0 mm

2 > 1.0 mm ≤ 2.0 mm

3 > 2.0 mm ≤ 3.0 mm

4 > 3.0 mm ≤ 4.0 mm

5 > 4.0 mm ≤ 5.0 mm



PIPE – MAINLINE

Section 33 11 10

Page 22 April 2019

.2 A thickness increment pay item only applies when the Contractor was required to increase the nominal liner tube thickness over the Specific Design liner to achieve the additional thickness required by the Special Design.

.3 In the proposal response, the Contractor shall, for each sewer section, list the specific nominal tube size to be used for the Specific Design Liner. See Statement E in the Request for Proposal.

.4 Where the Contractor considers that the increased in-place thickness necessitated by a Special Design can be achieved without increasing the nominal tube thickness over the specific nominal tube thickness, then the installation may be made with the specific nominal tube thickness at the Contractor’s discretion. However regardless of the nominal tube used, the in-place liner thickness shall meet the requirements of the Special Design. In the case where the Contractor opts to use the Proposal Design nominal tube thickness, there will not be a thickness increment for the nominal tube thickness and no increased thickness payment will apply.

.5 Where the Special Design Liner has been approved by the Owner, the Contractor will be paid for the liner thickness increase in accordance with the appropriate item in the Schedule of Quantities and Prices. Compensation for extra thickness will not be given in cases where liners are installed without prior approval by the Owner, through corresponding certified design approved by the Owner.

PART 3 - EXECUTION

3.1 FLOW CONTROL AND BYPASS

.1 Purpose

.1 Provide for bypassing and pumping of mainline sewage to maintain sanitary sewage flow in upstream sections of the sewer being lined. The contractor shall not let the upstream sewers surcharge beyond a reasonable amount, so as not to create any issues.



PIPE – MAINLINE

Section 33 11 10

Page 23 April 2019

.2 During the CCTV inspection of pre and post rehabilitation, sewer flows shall be bypassed in order to enable proper inspection of the pipe invert.

.2 General

.1 Flow Control means reducing or eliminating flow in the sewer section or sewer sections where lining is to be installed for the purpose of allowing the liner installation and facilitating associated activities, such as CCTV inspections. The method of achieving flow control is the responsibility of the Contractor subject to approval by the Owner.

.2 For the mainline sewer, flow control may include: Complete bypass pumping of the sewer section(s) requiring flow control, plugging and back-up of the upstream mainline sewer, pick-up of flows by vacuum tanker truck.

.3 For service connections, flow control may include: Temporarily backing up the service connections during lining installation (with notice and instructions to property occupants), bypass pumping of flows from service MHs, pick-up of service flows at service MHs (or other intercept points) by vacuum tanker truck.

.3 Complete Flow Control Required For:

CCTV inspection V2

Insertion and Curing of the CIPP liner until flow through the lined sewer section can be restored when the liner ends are opened for flow.

CCTV inspection V3

.1 Complete flow control means that there shall be no flow in the sewer section(s) and any fluid remaining in the sewer section shall be insignificant to the point that it will not interfere with or negatively affects the process underway during flow control, such as liner installation, liner cure or CCTV inspections.



PIPE – MAINLINE

Section 33 11 10

Page 24 April 2019

.2 No flow control or bypass pumping shall be employed that has insufficient capacity to maintain flow in the sewer system. It is the Contractor’s responsibility to employ flow control of sufficient capacity. No work requiring flow control shall proceed until flow control arrangements are in place that provide sufficient flow control capacity

.4 Flow Control During Other Work

.1 Partial or complete flow control may be required during other work when the presence of flow in the pipe negatively affects the quality of that work. In general the use and amount of flow control for other work will be at the Contractor’s discretion except when in the opinion of the Owner flow control is necessary for the Contractor to properly perform the work and obtain required results. Other work includes:

.1 Cleaning and preparation of the sewer section(s) to be lined

.2 Reinstatement of service connections into the lined sewer

.3 Any extra CCTV inspections required by the Owner

.5 Bypass Pumping

.1 Any surcharging of upstream sewer(s) shall not create any upstream problems such as property flooding or impeded mainline flow or impeded service flow.

.2 Flows shall be transported through a closed, leak tight pipeline or other method as approved by the Owner to the nearest or most economical disposal area.



PIPE – MAINLINE

Section 33 11 10

Page 25 April 2019

.3 On all liner installation time periods, the Contractor must maintain on site both a primary and stand-by by-pass pump and pump power supply as required to ensure sufficient flow control. The stand-by by-pass pump and power supply shall be of an equal or better capability than the primary by-pass pump and power supply. No by-pass pumps or related equipment shall be disconnected or removed from the sewer or job site until after all service connections have been reinstated, all by-pass equipment has been flushed/cleaned as approved by the Owner, and the Contractor has recorded the V3 CCTV inspection.

.4 All by-pass pumping shall be in place and operational prior to the final pre-installation inspection.

.5 All by-pass pumps and related equipment must be silenced equipment or contained within an acceptable sound reduction structure.

.6 Flow Control for Service Connections on the Sewer Being Lined

.1 When service connection flow control, the Contractor shall meet the following requirements:

.1 When private service back-up is used, advise building occupants of out-of service date and duration. Provide building occupants with instructions to limit water use.

.2 When private service back-up is used, the maximum out of service time shall be 8 hours.

.3 Make provisions to provide for residential bypassing as well as building bypassing of multi-unit residential, commercial, and industrial buildings (as determined by the Owner) from a clean out or property MH to maintain sanitary and storm sewage services to the property if required.



PIPE – MAINLINE

Section 33 11 10

Page 26 April 2019

.4 Make all necessary arrangements with the owners of each residence and/or building. The Contractor shall contact all property owners and/or tenants to co-ordinate the repair work to the sewer and minimize any impact on residents and/or businesses.

.7 Event of Loss of Redundant Capacity

.1 When circumstances arise requiring the use of redundant capacity and therefore redundant capacity no longer exists, action shall be undertaken immediately to restore the lost capacity to full function so that redundant capacity is fully restored. If redundant capacity cannot be restored, only critical work already in progress that must be completed (such as lining inversion, curing and liner end opening) shall proceed and without delay. No other work continuation (such as lateral reinstatements or CCTV inspection) shall take place without a fully functional redundant capacity.

.2 When it is known or suspected that redundant capacity is not or may not be fully functional, no work shall be started that requires bypass operation.

.8 Bypass Coordination and Supervision

.1 A Bypass Supervisor shall be assigned to manage all bypass pumping operations. The Owner shall be advised of this person and be provided with 24 hr contact information. When the bypass is required to operate, the supervisor shall assure that the bypass system is in full function operation, including fully available 100% redundancy before any work is started for which the bypass is required. When the bypass is in operation, the bypass supervisor will assure that there is continuous presence by a competent person to watch over the bypass including manual checking of upstream levels, pump fuel levels and other indications of potential trouble such as at pump suctions and discharges, discharge conduits and redundancy availability.

.9 Responsibility for Flow Control Leaks, Spills and Back-ups



PIPE – MAINLINE

Section 33 11 10

Page 27 April 2019

The camera equipment shall be capable of correctly focusing on locations being viewed and shall be equipped with adjustable focusing capability. The camera equipment shall be suitable for the size of the sewer. The picture on the CCTV monitor shall be an accurate representation of the inspection and shall have no on screen distortion such as vertical flattening or horizontal widening.

.3 The camera shall be located closely in the center of the pipe and shall provide a picture that properly and fully shows the full circumference of the pipe in sufficient detail to verify the interior details and features of the existing sewer or lined sewer meet with requirements (Cleaning and Preparation requirements, UV CIPP liner requirements and service connection reinstatement requirements). The camera equipment shall be provided with sufficient lighting of the viewing zone so that all details and features can be seen clearly and are not obscured by insufficient lighting or shadows both on the perimeter of the picture and in the direction of the view down the pipe. CCTV inspections with insufficient lighting will not be accepted.

.4 The view shall not be obscured by any vapour in the pipe. Where steam or other vapour obscures or otherwise interferes with the view, the Contractor shall take necessary action required to eliminate steam or vapour that interferes with the view.

.5 Where and when required for CCTV inspection, the pipe shall be sufficiently free of flow or standing water so that all surfaces can be fully inspected without any areas of features being obscured by water in the pipe. This will require flow control of flow during post cleaning and preparation CCTV inspection, CCTV monitored service connection reinstatement and final CCTV inspection of the completed UV CIPP liner.



PIPE – MAINLINE

Section 33 11 10

Page 29 April 2019

.6 The speed of inspection shall allow for proper viewing and inspection and shall not exceed 10 m per minute subject to requirements for pausing at service connections or other features, or as may be required by the Owner for specific situations.

.7 CCTV inspections shall be recorded on flash drive in a non-proprietary format compatible with Halifax Water’s CCTV viewing equipment and software. Each flash drive shall be clearly marked as to contents and date. One copy of each flash drive shall be provided to the Owner.

.8 The initial screen of any inspection shall record the inspection date, Contractor name, Contract identification information, location of the inspection, MH-MH section number(s), start and end MH numbers and the inspection type (e.g. Post Cleaning and Preparation, Final Inspection after Lining) and any other information routinely required for sewer CCTV inspections. The distance counter meters shall be zeroed at the starting MH and run continuously throughout the inspection. The section number shall appear continuously along with the distance count.

.9 At each service connection, the camera shall view the entire opening and up the service connection pipe (pan and tilting as required) for a minimum of 10 seconds or longer as necessary to view and record the complete details of the service connection.

Section 33 11 10

Page 31 April 2019

3.3 PRELIMINARY CCTV INSPECTION – V1

.1 The Contractor shall make a preliminary CCTV inspection (called the V1) of the sewer section before undertaking any work required for the UV CIPP lining of the section. The purpose of the V1 is to determine and record the initial condition of the sewer section and to determine if a significant changed condition exists versus the CCTV inspection provided to the Contractor by the Owner. Significant changed condition means a condition that will prevent lining of the section, require an unexpected excavated repair before lining, require a change in the liner design resulting in an increased liner thickness to deal with the changed condition or any other situation, which in the Owner’s opinion, is a significant changed condition.

.2 Where a significant changed condition is encountered, the Contractor shall immediately inform the Owner.

.3 In making the V1, the Contractor shall employ only such preliminary cleaning that is necessary to obtain a CCTV inspection sufficient to record the initial condition including a count and condition of service connections.

.4 De-watering of the sewer shall be sufficient for V1 inspection purposes and bypassing of the sewer flow shall be done where the sewer is not sufficiently clear for V1 inspection purposes.


.6 The V1 CCTV inspections shall be submitted to the Owner in accordance with the requirements of this specification.

Section 33 11 10

Page 32 April 2019

3.4 FILLING OF VOIDS

.1 Void Definition

.1 A void is a volume of space starting at the outside wall surface of the existing sewer where there is an absence of soil or ground material. Depending on its size and geometry the void may represent a structural weakness in the pipe/soil system that may continue after lining of the sewer. A void will often by evidenced by missing sewer pipe wall that has allowed the ground material to escape into the sewer, exacerbated by ground water infiltration. Where a void is deemed to create a significant structural weakness in the lined pipe, the void requires filling to re-establish the soil/ground support around the sewer.

.2 Voids Identified for Filling in the Contract

.1 The Contractor shall fill voids as specified for filling in the Proposal documents. Void filling shall ensure structural integrity of the lined sewer and prevent bridging by the liner. The Contractor shall submit for the approval of the Owner a detailed method statement outlining the procedures and materials to be used in filling the voids. The method statement shall correspond with requirements that may be specified for void filling in the Proposal document.

.3 Voids Requiring Filling Not Identified in the Contract



PIPE – MAINLINE

Section 33 11 10

Page 33 April 2019

.1 If, during the course of the work (such as during the V1 or cleaning and preparation), the Contactor identifies voids that require filling to ensure the structural integrity of the liner and to prevent bridging by the liner, the Contractor shall advise the Owner of these voids. Where the filling of such voids is required by the Owner, the Contractor shall submit a method statement outlining the procedures and materials to be used in filling the voids. Where the Owner requires filling of the voids, the cost shall be negotiated. However, this provision shall not apply to any voids created as a result of the Contractor’s work unless, and at the discretion of the Owner, the creation of such voids was an unavoidable repercussion of the work.

3.5 CLEANING AND PREPARATION OF EXISTING SEWERS FOR CIPP LINING

.1 General

.1 The sewer sections to be lined shall be cleaned and prepared to meet the requirements for lining including as follows.

.2 Precaution for Cleaning and Preparation

.1 The contractor shall take all reasonable steps to prevent the collapse or irreparable damage to the pipe wall (which would create the need for an open cut repair prior to lining) during the cleaning and preparation of the sewer sections. Should the contractor identify areas within the sewer sections which present a high risk for this situation to occur during cleaning and preparation, they shall notify the owner and present their recommended approach to avoid the potential collapse or damage.

.2 The sewer sections to be UV CIPP lined shall be cleaned and prepared to meet the requirements for lining including as follows.

.3 Soft Deposits and Loose Debris



PIPE – MAINLINE

Section 33 11 10

Page 34 April 2019

.1 All soft deposits shall be removed by suitable cleaning methods such as water jet sewer cleaning sized and rated for the sewer being cleaned. Soft deposits include such deposits as slime, grease and soft corrosion products. Loose debris includes such as soil, sand and contents of the sewer flow that have settled out of the flow.

.4 Corrosion Soft Deposits

.1 If the sewer is experiencing signs of corrosion, it may have areas of corrosion soft deposits. The severity of this corrosion and the type and depth of the corrosion products layers vary at different locations in the sewer sections. Where the depth of this layer is such that cleaning will cause exposure of the reinforcing steel (or where it is already exposed), the cleaning process shall be checked by CCTV to gauge the degree of removal and penetration into the pipe wall from the cleaning process.

.2 Where CCTV checking of the cleaning process indicates that full removal of soft corrosion layers is resulting in or may result in under-cutting of the reinforcing steel, soft layer removal operations shall be limited to not deeper than the outer surface of the reinforcing steel. The Contractor shall advise the Owner when cleaning and preparation operations in corroded sewers are creating, or will create a situation where it is advisable to scale back or halt such operations. On such advice, the Owner will advise the Contractor regarding the necessity for further cleaning and preparation.

.5 Hard Deposits

.1 Hard deposits, such as hard calcite shall be removed if they result in a diametric reduction of the sewer exceeding 15 mm. No hard deposits shall remain in place with sharp or ragged edges that will cause sharp indentations into the liner regardless of the diametric condition.



PIPE – MAINLINE

Section 33 11 10

Page 35 April 2019

.2 Hard deposits shall be removed using suitable equipment such as flailing or robotic cutting/grinding. The method of removal shall be such that no damage is caused to the pipe that will compromise the long-term structural performance of the rehabilitation.

.6 Tree Roots

.1 Any tree roots protruding into the inside of the pipe shall be sufficiently removed so that they do not interfere with the UV CIPP lining installation and the finished liner.

.7 Protruding Service Connections

.1 Any service connection to the sewer that protrudes into the inside of the sewer shall be trimmed back if the protrusion exceeds 12 mm. Regardless of the protrusion length, any sharp or ragged edged protrusions shall be trimmed smooth. Trimming shall be done with a method that does not damage either the service connection pipe or the mainline pipe. Robotic cutting is an acceptable method. Flailing with knocking devices is not an acceptable method.

.8 Disposal of Cleaning and Preparation Debris

.1 All debris, deposits etc. resulting from cleaning and preparation operations shall be removed from the sewer and not allowed to pass downstream or upstream from the sections to be rehabilitated. Disposal of cleaning debris and other waste products at an approved location is the responsibility of the Contractor.

.2 At the conclusion of cleaning and preparation, a CCTV inspection shall be made (the V2) and provided to the Owner for review and approval of the cleaning and preparation at least 2 days before lining installation. Refer to Section 3.7 .

3.7 POST CLEANING AND PREPARATION CCTV INSPECTION – V2.

.1 After completion of the cleaning and preparation of the sewer section (including all reaming, cutting, grinding and void filling) of the sewer section, a CCTV inspection (called the V2) of the full length of the sewer section shall be done. The V2 shall be done in accordance with the requirements of this standard.

.2 For the CCTV V2 inspection, the pipe shall have no active flow and any standing flow shall not impede assessing the post cleaning and preparation condition of the sewer. Complete flow control is required for the V2.


.4 The V2 complete with all reports shall be provided to the Owner at least 48 hours prior to lining for the Owner’s approval of the cleaning and preparation.

.5 On its discretion, the Owner may waive the requirement for the V2 to be submitted for approval 48 hours prior to lining, such as when approval for lining was provided at a live viewing of the V2 by a Halifax Water representative. However, in such cases the V2 submission shall always be submitted at a later time.

.6 Lining shall not commence until approval of the cleaning and preparation has been provided by the Owner to the Contractor.

.7 In the event that, after the V2, a deficiency in the cleaning and preparation is identified that requires correction, the V2 shall be redone after the correction has been done and the redone V2 submitted to the Owner.

.8 At the completion of cleaning and preparation for all sections, the CCTV inspections shall be consolidated on to one USB flash drive (or more than one as needed) and shall be in sequential order from upstream to downstream starting with the most upstream section.

CIPP Liner


The value of flexural modulus used for design shall take into account the expected long-term creep behaviour of the CIPP liner so that the use of the design value in the design formula(s) will yield a liner thickness that will perform as required for the design life. The flexural modulus design value shall be the short-term test flexural modulus reduced by the Creep Retention Factor (CRF) for the liner material. The CRF shall be established by ASTM D2990 (or equivalent) long-term testing. The short-term test flexural modulus used as the starting value before reduction shall be the value that will be reliably and repeatedly achieved in short-term testing of installation samples of the same liner material. The CRF shall be derived from long-term testing and be appropriate for stress and stress duration in the installed liner. Independent third party test data shall be available to substantiate the short-term test and

.4 General Requirements for Designs

.1 Design Certification and Clarity

.2 All designs shall be approved and stamped by a professional engineer licensed and authorized in the Province of Nova Scotia.

.3 All designs shall provide sufficient detail and clarity to allow for straightforward identification of the liner location (when for specific location) and design parameters used in the design. The design shall clearly identify whether it is a Proposal Design or a Special Design.

.4 Designs that are confusing or fail to properly identify the required design parameters will not be accepted.

.5 Design Thickness is the Minimum Required Finished In Place Structural Thickness.

.6 The UV CIPP liner wall thickness determined by design shall be the in place, completed liner thickness. Liner thickness measurements, either from samples or in ground, shall be compared to the design thickness for acceptance. Acceptance of final liner thickness shall be subject to reconciliation of actual required thickness based on tested liner properties. Where tested liner properties are different from the properties assumed in the liner design, the required thickness shall be determined by design reconciliation. Such reconciliation may change the required thickness for the final completed liner based on as tested properties. However in no case shall the required thickness be based on properties that are less than the minimum required properties or result in a required thickness that is less than the minimum thickness specified in the specification.

.7 Liner wall thickness measurements and determination of the actual effective thickness shall be in accordance with ASTM D5813-04(2008) or ISO 7685. Measurements of the actual installed liner wall thickness shall not include the thickness of any non-structural components.

Page 48 April 2019

.5 Short-term Flexural Modulus and Short-term Flexural Strength

.1 The short-term values of flexural modulus and flexural strength (as per D790) used as the starting values from which the long-term design values are derived shall be values that will be reliably and repeatedly obtained in the installed liners as substantiated by testing samples from installed liners. These short-term values shall be identified in the liner design.

.6 Substantiation of Liner Physical Properties Used for Design

.1 It is the responsibility of the Contractor to obtain third party testing of the CIPP liner sufficient to substantiate the liner material properties used in design. Once a liner installation has been completed, the Contractor shall provide the substantiated test results and other information to the Owner for review and approval within ten (10) business days of the liner installation (i.e. date sample is signed by the Owner).

.2 Substantiation, at a minimum, will include ongoing third party testing results for short-term properties of flexural modulus and flexural strength on installed liners showing that the properties assumed in design are routinely achieved in the field for the same materials being used for this contract. Substantiation must also include the basis for long-term properties including, at a minimum, long-term (10,000 hr) testing on the resin being used for flexural strength and flexural modulus. For reinforced liners, long-term testing must be on the complete liner product itself, not just for the resin element.

Page 49 April 2019

3.12 CIPP LINER MINIMUM THICKNESS

.1 All UV CIPP liners shall achieve the minimum in place final completed thickness of at least the design thickness or 4.0 mm, whichever is greater.

.2 Where a design thickness is lower than the minimum thickness, the design shall note this and indicate that the minimum thickness is the required liner thickness for the liner installation covered by the design. This applies to both Proposal Designs and Special Designs.

.3 A design reconciliation based on installed liner test properties (such as from testing field samples of liners) shall not overrule the requirement for minimum thickness.

3.13 CIPP LINING – RESIN IMPREGNATION

Section 33 11 10

Page 51 April 2019

.6 Service connection openings in the liner shall match the size and shape of the existing service connection in the mainline sewer. Openings shall be smooth and clean. Finished openings shall be without protrusions, hanging material, shavings, lips or obstructions to sewage flow from the service connection into the interior of the liner. Over-cutting shall be avoided. Service connections, that in the Owner’s opinion, are over-cut may be deemed defective and require a UV CIPP sleeve spot repair followed by reinstatement of the service connection by the Contractor as remedial action, at no cost to Halifax Water.

.7 The existing service connections shall not be damaged. The Contractor shall repair any damage to the existing service connections that occurs during the re-instatement, to the satisfaction of the Owner, at no cost to Halifax Water.

.8 Where a service connection is visibly fully plugged and is an apparent dead connection, the Contractor shall advise the Owner of this finding. With the approval of the Owner, such connections will not be reinstated.

.9 Reinstated service connections shall be recorded on the SCS with the dates and times of partial and complete reinstatement.

3.16 MANHOLE BENCHING AND RESTORATION

.1 All affected manholes shall be re-benched, where required, to conform to the dimensions and positions of liners.

.2 Where a liner has been placed continuously through a manhole, the benching shall be made to conform to the exterior of the liner. The liner shall be opened the full width of the manhole (from pipe entrance to exit) for the top half diameter of the liner. Finished liner and benching in manhole shall provide a smooth, uniform flow path from entrance to exit at uniform grade.

.3 Where lining work necessitated or resulted in damage to the manhole or the manhole benching, it shall be restored to equal or better than original condition and shall meet the requirements for benching as previously specified.

.4 Material for benching work shall be Speedcrete, 20 MPa or approved equal.

3.17 CIPP LINING COMPLETED CCTV INSPECTION (V3)

.1 After completion of a sewer section rehabilitation (including reinstatement of service connections and MH benching) the Contractor shall complete a full CCTV inspection of the sewer section (called the V3).

.2 Where MH rehabilitation is being completed in coordination with UV CIPP Lining, the V3 shall include the complete upstream (US) and downstream (DS) MH rehabilitation liners. The V3 video will pan around the rehabilitated US MH and DS MH ensuring that the complete MH liner is visible. The pan around of the MHs will include visibility of the MH walls, benching, and the finished seal (i.e. interface) between the UV CIPP Liner and MH Liner material.

.3 Each reinstated service connection shall be viewed in its entirety for 10 seconds, or a sufficient time for properly judging the re-instatement.

.4 The CCTV inspection shall be provided on a flash drive that shall be clearly identified with Contract Number, street name, section number, begin/end manhole numbers and date of the CCTV inspection.

.5 In the event that a deficiency in the sewer section rehabilitation is identified after a Post Rehabilitation CCTV Inspection (V3) that requires any repair of remedial works to the section, the V3 Post Rehabilitation CCTV Inspection shall be repeated after the repairs or remedial action have taken place.

.6 Flow control shall be required as such to ensure a clear view of the installed liner during the V3.

.7 Sewer defect coding is required for the V3.

3.18 INSTALLED CIPP LINER FIT AND FINISH REQUIREMENTS



PIPE – MAINLINE

Section 33 11 10

Page 53 April 2019

.1 The finished lining shall fit neatly and tightly to the existing sewer without significant fins or excessive wrinkling. Any annulus gap between the liner and the existing sewer inside surface shall be in accordance with industry standard shrinkage characteristics for properly installed and curedUV CIPP. Annulus gap which is due to improper liner sizing, inadequate preparation of the existing sewer, improper installation, curing or cooling, or the effect of ground water pressure will not be accepted.

.2 The liner shall extend continuously from MH to MH starting and ending at the inside walls of the MH (except where lining is made through intermediate MHs).

.3 The completed installed liners shall conform to the following requirements.

Continuity of Liner

The finished liner shall be continuous over the entire length of the liner installation from MH to MH without any breaks, separations or joints.

Liner Fit to Existing Sewer Liner

The outside surface of the finished liner shall be in contact with the inside surface of the existing sewer subject to the contact tolerance. The inside surface of the existing sewer is the surface after the sewer has been cleaned and prepared for lining in accordance with the cleaning and preparation requirements. The contact tolerance is 1.0 mm. Where any space of gap between the outside surface of the liner and the inside surface of the existing sewer line exceeds 1.0 mm, the liner fit will be deficient, subject to exceptions noted below.

The liner should also be able to negotiate vertical/horizontal elbows and bends with various degrees (angles ranging from 0 to 45 degrees).

Exception to Liner Fit at Existing Sewer Line Irregularities

Existing sewer line irregularities include off set joints, protrusions, bumps or other similar situations in the existing sewer that remain after the sewer has been prepared in accordance with the cleaning and preparation requirements. Neither ovalisation of the existing sewer nor curves made by joint deflection are irregularities in this context. Where an irregularity exists, exception to the liner contact tolerance requirements will be allowed in the irregularity zone. The irregularity zone is defined as a zone extending a distance of up to ¼ of the liner inside diameter in any direction from the irregularity as measured along the inside surface of the liner.



PIPE – MAINLINE

Section 33 11 10

Page 54 April 2019

A liner fit exception at an existing sewer irregularity shall not present an obstruction to sewage flow whether or not it complies with the allowed exceptions.

Liner Shape

The liner shape will be as defined by liner fit to existing sewer line. In general the liner shape shall conform to the shape of the existing sewer line inside surface after its cleaning and preparation in accordance with requirements. However, where the existing sewer line shape is not defined (missing pieces of sewer line) the liner may either bridge the missing wall section or indent into the missing wall section. Where the liner bridges, the shape of the liner shall match the shape of adjacent sewer line and the inside diameter of the liner shall be as required for Contact Tolerance for the adjacent sewer line. Where the liner indents, the depth of the indent shall not reduce the liner wall thickness below the Wall Thickness Tolerance.

Liner Wall

The liner wall shall be free of any interior bulges, ribs, ripples, folds or other irregularities except where these irregularities comply with the Liner Wall Thickness Tolerance, fit, shape and wall thickness given above. The wall of the liner shall be free of any voids (dry spots), cavities or bubbles.

Liner Terminations

At manhole entrances and exits the interface between the exterior surface of the liner and the manhole shall be watertight to the requirements for external hydrostatic pressure. The finished ends of the liner shall be neat and smoothly cut. The benching in the manholes shall be modified where required to conform to liner dimensions.

The liner shall extend into each MH a minimum of 12 mm (½”) and a maximum of 25 mm (1”), such that the MH liner material application can be applied to the back (outer surface) of the liner, creating a seal around the CIPP liner, pipe and MH interface.

Bulges, including Lifts and Sags

There shall be no bulges in the liner that are not consistent with the surface profile of the existing sewer before lining. Such bulges will be considered an indication of a major structural deficiency in the liner and will require major remedial action. Where bulges are suspected or proven to contain internal separations within the wall of the liner, remedial action up to and including removal and replacement of the liner will be required. This applies to bulges that may be called lifts or sags.

3.19 LINER WALL THICKNESS AND TOLERANCE

.1 General

.1 The liner's finished structural wall thickness shall be as specified in the applicable liner design approved by the Owner. The required structural wall thickness may also be determined by a design reconciliation using test properties done by the Owner.

.2 The effective liner wall thickness shall be determined in accordance with ASTM D5813-04(2008) or ISO 7685.

.3 The wall thickness tolerance is:

Minus 0%

Plus 25%.

.4 The wall thickness under consideration is the final cured-in-place thickness and shall not include any layers or material that does not contribute to the structural rating of the liner.

.2 Liner Thickness

.1 Finished liner thickness shall be no less than the design thickness or specified minimum thickness, whichever is greater. Thickness shall be determined in accordance with the provisions of ASTM D5813-04 (2008) or ISO 7685. The effective thickness of the liner shall be either the average thickness or the minimum thickness multiplied by 0.875, whichever is less.

.2 Required liner thickness shall be subject to design reconciliation based on UV CIPP properties determined in as installed liner sample testing. Such design reconciliation may require a different liner thickness (versus the original design thickness) to correspond with design based on as installed sample tested properties. In no case shall a design reconciliation result in a required liner thickness that is less than the specified minimum thickness.



PIPE – MAINLINE

Section 33 11 10

Page 56 April 2019

3.20 INSTALLED CIPP LINER PHYSICAL PROPERTIES REQUIREMENTS

.1 The complete installed liner shall have the following required physical properties:

.1 Short-term Test Flexural Modulus: Shall meet or exceed the value used in the applicable liner design

.2 Flexural Strength: Shall meet or exceed the value used in the applicable liner design

.2 In the case of long-term design values of flexural modulus and flexural strength used in design, the liner shall possess the required long-term retention characteristics such that the long-term values used in design will be met by the liner over its design life.

3.21 SAMPLES AND TESTING OF INSTALLED CIPP LINERS

.1 General

.1 The Contractor shall provide and have tested samples of the liner installations at the sampling rate indicated below. The testing shall be done at an independent testing agency experienced in testing UV CIPP samples and approved by the Owner.

.2 Testing will determine the short-term test flexural strength, the short-term test flexural modulus, structural thickness and any other relevant properties of the cured liner as represented by the samples. Test results must meet the values of short-term test flexural modulus and flexural strength used in the applicable liner design provided by the Contractor and the thickness determined by that design.

.3 Unless otherwise approved by the Owner, liner samples and testing shall be required for all liner run installations. Each sample must be identified, dated and signed by the Owner prior to leaving the project site. Payment for samples will be made per the payment item.



PIPE – MAINLINE

Section 33 11 10

Page 57 April 2019

.4 Samples shall be delivered to the independent testing agency designated below in a timely manner, such that test results are provided to the Owner within 10 business days after liner installation. Should samples not be submitted; the Owner, at their discretion, may issue a suspension of work order for UV CIPP lining until such time that the test reports are submitted.

.5 Testing Agency to by Used: Paragon Systems, Concord, Ontario. 905-738-0447

.2 Sample Requirements

Sample Quantity One sample per continuous liner installation, unless otherwise approved by the Owner.

Location Upstream MH, downstream MH, intermediate MH or other location that yields a suitable sample



PIPE – MAINLINE

Section 33 11 10

Page 58 April 2019

.1 Where space prevents a single piece form, a multi-piece form shall be used that can be assembled and dis-assembled in the MH.

.2 Where a multi-piece form is impractical or impossible, samples taken from pieces of liner removed in the liner opening process may be suitable for testing purposes.

.3 Sampling Methodology

.1 The sample size shall be suitable to obtain sufficient test coupons for either ISO 11296 or ASTM D790 testing (as applicable to sample type) for flexural strength, flexural modulus and for measuring liner thickness around the circumference depending on the type of sample and how it is tested.

.2 For sewer sizes up 375 mm the sample type shall be restrained cylindrical samples made in full circumference forms positioned in a MH, through which is run an extension of the liner being installed. The inside diameter of the forms shall be the same as the inside diameter of the sewer being lined. The form shall have sufficient strength such that it does not expand under the heat and pressure of the liner installation and cure process. The length of the form shall be sufficient to provide a sample of liner 400 mm long. The forms shall be covered with material to maintain a cure heat environment similar to the cure heat environment for the liner within the sewer pipe.

.3 For sewer sizes larger than 375 mm, if it is not possible or practical (due to space, access or safety limitations) to obtain formed cylindrical sample, then samples taken from pieces of cured liner removed in the liner opening process may be suitable for testing purposes.

.4 When samples from pieces of cured liner are not suitable or are not representative of the liner within the sewer, then a sample shall be cut from the liner within the sewer.

.5 Samples Cut From Liner Inside the Sewer



PIPE – MAINLINE

Section 33 11 10

Page 59 April 2019

.6 Where a test sample is required and there is no other method of obtaining it, a sufficiently large sample shall be cut out from the liner within the pipe. The configuration of the cut out sample shall allow for ISO 11296 test method (curved test coupons from around the circumference of the liner). The removed section of liner shall be repaired with a fibre reinforced cementitious rehabilitation product such as Centri Pipe PL 8000 or approved equivalent.

.4 Deficient Sample

.1 In the event a sample is deemed deficient, either by the Owner or by the Contractor, because they are either inadequate for testing or considered not representative of the liner within the sewer, the Contractor shall obtain a new sample of the liner that is not deemed deficient either by the Owner or the Contractor. All costs associated with the provision of such a further sample shall be the responsibility of the Contractor including any costs incurred by the Owner such as for inspection during obtaining of the new sample, testing and design calculation reconciliation for the new sample.

.2 Where obtaining such new samples requires repairs or restoration to be made to the liner or sewer (such as a sample removed from within the lined sewer) the Contractor shall provide a plan for making such repairs or restoration that is acceptable to the Owner. It shall be at the Owner’s sole discretion whether such a plan is acceptable. The cost of making any such repairs shall be paid by the Contractor.

3.22 SAMPLE TESTING, RESULTS AND RECONCILIATION

.1 Sample Testing

.1 The Contractor will have testing done by Paragon Systems, Concord Ontario, 905-738-0447. Copies of all test reports will be provided to the Owner.



PIPE – MAINLINE

Section 33 11 10

Page 60 April 2019

.2 The Contractor shall arrange that the Owner may speak with Paragon Systems about the samples and sample testing and samples and arrange with Paragon to allow Paragon to send the test reports to the Owner.

.3 The sample test results shall meet or exceed to the values for thickness, short-term test flexural strength and short-term test flexural modulus in the approved applicable liner design for the sample location liner.

.4 When any of the sample test results (Flexural Modulus, Flexural Strength or Thickness) are not in accordance with the applicable design submission values, then the liner shall be deemed apparently deficient until the sample test results are reconciled.

.5 In the event that sample test results do not meet requirements, the procedure for reconciling sample test results shall be used by the Owner for determining whether the corresponding installed liner is acceptable. Should the liner not be acceptable, the Contractor shall provide a plan for remedial action that is acceptable to the Owner.

.2 ISO Methods Testing

.1 The ISO testing methods shall be used for all restrained cylindrical samples and any samples cut out from the liner within the sewer.

.2 The ISO 11296 is the preferred test method for flexural properties of reinforced UV CIPP as it better captures the effect of the reinforcing than the ASTM D790 method.

.3 The ISO 11296 method tests curved coupon that is cut out around the circumference of liner sample. This requires either a restrained cylindrical sample of liner, which is made in a cylindrical form with a form inside diameter very similar to the inside diameter of the sewer being lined or a sample cut out of the liner within the sewer.

.4 When the ISO 11296 test method is used, the structural thickness shall be determined by ISO 7685



PIPE – MAINLINE

Section 33 11 10

Page 61 April 2019

.3 ASTM Methods Testing

.1 The ASTM testing methods shall be used for any samples from which it is not possible to obtain the test coupon configuration required for the ISO testing methods.

.2 The ASTM D790 tests straight and flat coupons cut from the liner sample along its length. This type of coupon can be cut from a cylindrical formed restrained sample or other available pieces of liner large enough for obtaining test coupons. When using the ASTM D790 method, a cylindrical restrained sample is the preferred sample as it better represents the liner inside the sewer than either random pieces of liner or formed flat plate samples.

.3 The ASTM D790 test method tends to produce lower results than the ISO 11296 method because the ISO method using the curved sample captures the effect of the liner reinforcing better than the ASTM method.

.4 When the ASTM D790 test method is used, the structural thickness shall be determined by ASTM 5813

.4 Test Results Requirements

.1 The test results for short-term test flexural modulus and short-term test flexural strength shall meet or exceed the values for these parameters used in the applicable liner design.

.2 The test result for structural thickness shall meet or exceed the minimum structural thickness determined by the applicable liner design.

.3 When sample test results do not meet requirements the liner will be deemed deficient subject to Design Reconciliation.

.5 Sample Test Reports

.1 All test reports received shall at a minimum include the following;



PIPE – MAINLINE

Section 33 11 10

Page 62 April 2019

.2 Header information identifying the sample as described on the sample in addition to HW contract number.

.3 Date sample was received and date when sample was tested.

.4 Photograph of the sample as received, both side and end profile

.5 Identification of each test performed and its associated results

.6 Graphical presentation of the flexural property test from beginning of applied loads to end of test.

.7 Photograph of each broken specimen identified by the specimen number used to report the test result.

.8 Signature of technician who completed the test and signature of report reviewer.

.9 Copy of the Chain of Custody (COC) form

.6 Summary sheet of all samples taken and tests completed under the contract (referenced by the HW Contract Number) shall be provided with the final delivery of test reports.

.7 Design Reconciliation for Sample Test Results

.1 The applicable liner design will be recalculated using the test values for short-term flexural modulus and short-term flexural strength. All other input parameters remain the same. This is known as Reconcile Design at Test Properties (RDATP). An RDATP is not applicable if properties are below any minimum requirements in this specification or in the applicable ASTM Standard for the liner.

.2 If the test thickness meets or exceeds the reconciled thickness, the liner is not deficient regarding sample test results. Otherwise the liner is deemed deficient.

.3 Proceeding with Reconciliation requires that sample be, in the opinion of the Owner, representative of the liner in the sewer.

3.23 LINER DEFICIENCIES AND REMEDIAL MEASURES

.1 General

.1 When the Contractor is aware of any deficiencies in the work or in the results of the work, the Contractor shall advise the Owner of these deficiencies within 48 hours including situations where the deficiency has already been rectified.

.2 Where a liner is deficient, the Contractor shall rectify the deficiency(s) with a remedial method that is acceptable to the Owner. Where there is no remedial method acceptable to the Owner, the liner shall be removed and replaced at no cost to Halifax Water.

.3 The specific deficiencies addressed below are examples and do not represent all the deficiencies that may occur.

.2 Thickness Less than Required Thickness:


.3 Physical Properties Less than Required Properties


.4 Dry Spots, Lifts, Delamination and Other Deficiencies

.1 The finished pipe shall be continuous over the entire length of a new installation and shall be free of dry spots, lifts and delamination. If these or other conditions, which are not in compliance with this specification, are present, the Contractor shall repair the defects at their own cost, to the Owner’s satisfaction. In the event the CIPP does not fit tightly against the host pipe at its terminal points, the space between the pipes shall be sealed with a resin mixture compatible with CIPP.

.5 Excessive Fining or Wrinkling



PIPE – MAINLINE

Section 33 11 10

Page 64 April 2019

.1 Excessive liner material shall be removed to the acceptance of the Owner. Where excessive material cannot be removed without compromising the structural integrity of the liner, the Contractor shall take other remedial action as acceptable to the Owner.

.6 Bulges, Lifts and Sags

.1 There shall be no bulges in the liner that are not consistent with the surface profile of the existing sewer before lining. Such bulges will be considered an indication of a major structural deficiency in the liner and will require major remedial action. Where bulges are suspected or proven to contain internal separations within the wall of the liner, remedial action up to and including removal and replacement of the liner will be required. This applies to bulges that are may be called lifts or sags.

.7 Remedial Action

.1 Where deficiencies are identified, the Contractor shall perform the accepted remedial action in a timely manner without unreasonable delay.

.2 Where a deficiency will seriously impact sewer or service connection flow capacity and are considered likely to cause sewer back-ups onto properties or other overflows, the Contractor shall take immediate action to prevent such problems without waiting for acceptance of remedial method from the Owner. In such case, the final resolution of a deficiency, if required, shall be by a method acceptable to the Owner.

.3 The contractor shall provide the Owner with a list of all the identified deficiencies prior to any remedial action. The list shall include the location of the deficiency and the remedial action required to rectify the deficiency, along with the associated CCTV video inspection.

.4 The cost of any work to rectify a deficiency is the responsibility of the Contractor.

3.27 EXCAVATION FOR RETRIEVAL OF EQUIPMENT OR OTHER PURPOSES

.1 Where the retrieval of lodged equipment is required by open-cut excavation, the Contractor shall provide for retrieval including any excavation, maintenance of flow, repair, backfill and restoration (as per Contract requirements) as required. However, if the equipment became lodged in a portion of a sewer section for which no previous CCTV inspection or other advice was provided to the Contractor by the Owner then the Owner will pay the Contractor for 75% of the total above noted cost only if such cost occurs during the preliminary video inspection (V1) or during preliminary cleaning operations for the V1. However, the Owner will not approve any other associated cost related to this work.

.2 If it is necessary to excavate for any reason such as repair of defective liner, reinstatement of service connections, by-pass of flow, etc., the Contractor shall provide such excavation, repair, backfill and restoration (as per the Contract requirements) as required. However dependent on the reason why an excavation is required and at the discretion of the Owner, additional payment for such work may be negotiated with the Contractor. In such case where the work is determined by the Owner to be extra to the contract, the work shall not proceed without the approval of the Owner prior to the work.

.3 All such work shall be performed by an approved sub-Contractor (when required by the Owner) and shall be completed in accordance with the Contract specifications.

.4 No claim for lost time will be considered as a result of any occurrence in which previous information was provided (i.e. conditions in CCTV video were provided).
