.1 Existing concrete deck surface shall be removed by use of scarification (roto-milling),hydro-demolition or alternate methods acceptable to Consultant over the full length and


width of the bridge deck. Alternate methods shall meet the requirements as specified forscarification.

.2 If scarified, equipment shall be capable of removal to an accuracy of ± 5 mm. Thescarifying equipment shall produce a surface between 3 mm and 6 mm in amplitude forroughness. The maximum cut will be to within 10 mm of the reinforcing steel. Depth ofscarification will be specified on the drawings or by Consultant. Contractor shall monitorthe total depth of concrete cover to the top mat of reinforcing steel using a pachometer oralternate methods acceptable to Consultant. Readings shall be taken at regular intervalsahead of the scarification.

.3 Contractor shall adjust the rate and depth of concrete removal to ensure that thereinforcing steel is not damaged and the desired scarified profile is achieved. Allreinforcing steel damaged by Contractor’s operations will be replaced at Contractor’sexpense to the satisfaction of Consultant.

.4 Prior to bridge deck removal, all existing expansion joint seals, armouring, and otherimpedances shall be removed.

.5 Provide adequate guards to control overspray or flying debris during scarification, waterblasting, deck washing, and chipping processes.

.6 All areas inaccessible to the scarification equipment shall be prepared by hydro-demolition, grinders or by jackhammers that are limited to a maximum 7 kg.

.7 Concrete shall be removed to approximately 10 mm above the existing deck reinforcingsteel.

.8 Conduct a deck delamination survey, with Consultant, and locally subexcavate alldelaminated concrete by chipping. Subexcavation shall be to a depth of 25 mm below thereinforcing steel mat or to sound concrete, whichever is greater. Locally clean existingreinforcing steel and where there is significant section loss, replace steel, as directed byConsultant.

.9 Water blast the surface of the entire concrete subdeck no earlier than 2 days beforeplacing the concrete overlay. A minimum water blast pressure of 110 MPa (15000 psi) @68 litres/minute shall be applied using a rotating head.

.10 Contractor shall provide full containment and disposal of all debris and shall comply withall applicable environmental and Workers Compensation Act, Occupational Health andSafety Regulations BC requirements.

.11 Contractor shall protect the prepared sub-deck from contaminants until the concreteoverlay is placed.

.12 Vehicle traffic shall not be allowed on the bridge deck after scarification has beencompleted.

3.3 PLACING CONCRETE

.1 Install rigid forms (made of wood or steel) at longitudinal bulkheads in a manner that willmaintain the required boundaries during concrete placement, consolidation and finishing.The longitudinal bulkhead shall be installed near the lane markings. The top of thelongitudinal bulkhead shall be set at the finished deck elevation. Any honeycombing orpoorly consolidated concrete observed after stripping the longitudinal bulkhead shall becut back into the new overlay a minimum of 150 mm.


.2 Ensure that rate of placing is sufficient to complete proposed placing, finishing andinitiation of curing operations within one single, continuous placing operation; thatexperienced finishing equipment operators and concrete finishers are provided to finishdeck; that curing equipment and finishing tools and equipment are on site and insatisfactory condition for use.

.3 Do not place concrete until rails for support and operation of finishing equipment are inplace and firmly secured.

.1 Rails to be of a type and so installed that no springing or deflection will occurdue to weight of finishing equipment and so located that finishing equipment canoperate without interruption over entire bridge roadway deck being finished.

.2 Extend rails for finishing equipment beyond both ends of scheduled length ofconcrete placement a sufficient distance to permit float of finishing equipment tofully clear concrete to be placed.

.3 Set rails or headers to elevations, with allowance for anticipated settlement,camber, and deflection of falsework, as required to obtain a bridge roadway decktrue to required grade and cross section. To confirm the adjustment of thefinishing equipment and guide rails, the screed shall be dry run in the presence ofConsultant and clearance measurements taken at each point and provided toConsultant. Resetting of the equipment and/or guide rails shall be made asnecessary to achieve an acceptable dry run. Adjustment to the equipment or therails shall not be made after an acceptable “dry-run” is complete withoutConsultant.

.4 Do not place overlay concrete if rain, strong winds or otherwise unsuitable weather isforecast. Alternatively, provide tenting or hoarding to protect the freshly poured concretefrom the unsuitable weather. Protect the freshly placed concrete overlay from drying asdetailed in CAN/CSA A23.1.

.5 Immediately prior to placing, check falsework and wedges and make necessaryadjustments.

.6 Deck areas to be overlain are to be re-cleaned with a minimum of 35 MPa (5,000 psi)water blast. The surface shall be continuously wet for 3 hours before the bonding slurryis applied, and all free water must be removed to obtain a Saturated Surface Dry surfacejust prior to bonding slurry application.

.7 Apply cementitious bonding slurry ahead of concrete placing. The bonding slurry shall beapplied by spraying just ahead of the concrete placing operation. At no time shall thebonding slurry be placed more than 3 m in front of the advancing concrete, nor shall thebonding slurry be allowed to sit on the deck surface for more than 15 minutes. In theevent that the bonding slurry does dry, Contractor shall hose the bonding slurry off of thedeck while preventing any contamination of the concrete being placed and replace dryslurry before concrete is placed.

.8 The spraying equipment used to apply the bonding slurry shall produce an even coatingsufficiently thick to appear uniformly moist and it shall not run or puddle. Consultantshall determine whether areas require re-spraying. The equipment utilized shall propelthe bonding slurry at sufficient velocity that no air voids exist between the deck and thebonding slurry. The bonding slurry shall be frequently re-mixed as it is being used andshall not be older than 30 minutes. Contractor shall use a stiff bristle broom to removeexcess sprayed bonding slurry from the deck rebar and deck surface. Contractor shall


ensure that the bonding slurry is evenly dispersed and coats the full area of the concretedeck surface below the grillage of rebar. The use of the stiff bristle broom may benecessary to ensure that this is achieved. The slurry must not exceed 3 mm in depth.

.9 Place concrete in a uniform heading normal to structure centreline. Limit rate of placingto that which can be finished before beginning of initial set.

.10 Deliver concrete to the final point of placement in a manner that prevents segregation ofthe concrete and does not contaminate the prepared surface.

.11 Fully consolidate concrete by means of a finishing equipment that incorporates avibratory action, augmented by a minimum of two hand held vibrators for consolidatingconcrete at edges.

.12 If concrete placement is stopped for longer than 30 minutes, install a bulkhead to preparea construction joint if so instructed by Consultant.

.13 Immediately after concrete has been placed and consolidated, strike off surface. Correctimmediately any improper adjustment and operation which results in unsatisfactoryconsolidation and smoothness. Unsatisfactory performance may be cause for rejection ofequipment and removal of concrete in place.

.14 Following completion of strike off by hand methods, float roadway slab surfacelongitudinally to a smooth uniform surface with hand operated wood float boards 3.5 to 5m long, minimum 25 mm thick, minimum 200 mm wide, ribbed and trussed as necessaryto provide a rigid float, and equipped with adjustable handles at each end. Provideadjusting screws spaced at maximum 600 mm centres between float board and rib.Maintain float board true to line and free of twist.

.15 Use floats to remove roughness and minor irregularities left by finishing equipment andto seal concrete surface to approval of Consultant. Excessive working of surface is notpermitted.

.16 Adjust rails or headers as necessary to correct for settlement or deflection which occurduring finishing operations. Operate finishing floats from transverse bridges that spanarea being floated. Provide sufficient number of work bridges to permit operation offloats without undue delay.

3.4 FINISHING

.1 Finishing bridge deck slab: when concrete has hardened sufficiently to preventdislodgement of coarse aggregate particles, give surface a uniform transverse tined finishfree from porous spots, irregularities, depressions, small pockets or rough spots.

.2 Finishing sidewalk slab: when concrete has hardened sufficiently to prevent dislodgementof coarse aggregate particles, give surface a uniform transverse broomed finish, oralternative finishing method approved by Consultant, free from porous spots,irregularities, depressions, small pockets or rough spots.

.3 Finish surface to within 3 mm in 3 m from line, level or grade as measured with a straightedge placed on surface.

.4 If flatness is unacceptable and in a 4-10 mm tolerance range, grind the surface ofhardened concrete and restore tining with grooving equipment to provide a skid resistantsurface. For deviation from flatness greater than 10 mm, remove and replace concrete


using procedures as specified for unsound concrete in this specification, or as acceptableto Consultant, at the expense of Contractor.

3.5 PROTECTION AND CURING

.1 Concrete temperature shall not exceed 17ºC at time of placement.

.2 For concrete placed when ambient air temperature is below 5ºC comply with the coldweather requirements of CAN/CSA-A23.1. Concrete shall not be placed when theambient temperature exceeds 25ºC. Concrete more than 45 minutes old shall be rejected.

.3 Unformed surfaces: cure with burlap and water. Carefully place two layers of dampburlap on the surface of the concrete as soon as practicable following placement. Overlapeach strip by at least 75 mm and secure against displacement by wind. Maintain burlap inplace and keep thoroughly and continuously wet for seven days after day of placing.Provide misting as described in CAN/CSA A23.1 and according to CAN/CSA A23.1Appendix D. Do not use a membrane curing agent.

.4 Formed surfaces: if formwork is left in place for seven days or more, no additional curingwill be required. If formwork is removed in less than seven days, cure in mannerspecified for unformed surfaces for remainder of seven-day period.

.5 During curing period uncover only such areas as are immediately needed for finishtreatment. Recover and continue curing.

.6 The overlay shall attain a minimum strength of at least 30 MPa before removal of theburlap and opening to traffic. All other requirements of seven-day curing shall be adheredto.

GEOTECHNICAL REPORT

November 13, 2018 File: 11040 Associated Engineering (B.C.) Ltd. #500 - 2889 East 12th Avenue Vancouver, B.C. V5M 4T5 Attention: Grant Fraser, P.Eng.

BASTION BRIDGE SEISMIC RETROFIT PROJECT CITY OF NANAIMO, BC

GEOTECHNICAL ASSESSMENT AND RECOMMENDATIONS Dear Grant: As authorized, Thurber has completed an engineering assessment and prepared geotechnical recommendations for seismic upgrades of the Bastion Bridge, located in the City of Nanaimo, B.C. It is a condition of this letter that Thurber’s performance of its professional services is subject to the attached Statement of Limitations and Conditions.

1. INTRODUCTION The City of Nanaimo (the City) has authorized Associated Engineering (AE) to complete an evaluation and provide recommendations for a seismic upgrade to the Bastion Bridge. The bridge, built in 1936 and upgraded in 1978, is approximately 86 m long and is supported by three reinforced concrete piers and concrete abutments. It spans over Terminal Avenue (Trans-Canada Highway) and connects Fitzwilliam Street and Bastion Street. According to the 1936 structural drawings:

• The abutments are supported on shallow footings that bear on rock. According to the 1979 construction record drawings, the abutment footings measure approximately 9 m in width. However, the length or thickness of the abutment footings is not reported.

• Pier 1 is shown to be supported on a shallow footing but it is not clear if it is bearing on rock or on structural fill.

• Piers 2 and 3 are supported on cast-in-place concrete pile caps with 25 precast, reinforced octagonal concrete piles. The pile cap measures approximately 3.4 m by 10.9 m (11 ft x 36 ft) in area and 1.2 m (4 ft) in thickness, and the piles measure 508 mm (20 inch) in diameter with a centre-to-centre spacing of 1.2 m (4 ft). The pile group consists of three rows, with the exterior rows including 8 piles and the interior row including 9 piles. The piles were terminated in bedrock and are likely to be spliced.

Client: Associated Engineering (B.C.) Ltd. Date: November 13, 2018 File No.: 11040 E-File: 20181113_tfd_Geotechnical Assessment and Recommendations_11040 Page 2 of 6

Our scope of work is to complete a geotechnical assessment and provide geotechnical recommendations for the contemplated seismic upgrade. Assessment of soil and groundwater contamination is not included in our scope of work. 2. SUBSURFACE CONDITIONS According to the geologic maps, the general stratigraphy comprises sedimentary rock at shallow depths. Terminal Avenue, however, has been constructed over a historic channel that was infilled with uncontrolled fill. AGRA Earth and Environmental (AEE) completed a geotechnical investigation in July 1996 that included air rotary test holes and Becker penetration test (BPT) profiling near the pier locations. The subsurface conditions comprised variable very loose/soft to firm sand, gravel, clay and silt layers over a gravel unit that is underlain by bedrock. The depth to bedrock varied and was encountered at 5.6 m, 11.3 m and 11.9 m depths at Piers 1 to 3, respectively. Groundwater was observed in all test holes, between depths of 4.4 m and 4.6 m. Groundwater levels may vary in response to periods of prolonged and intense rainfall and, conversely, to extended periods of dry weather. 3. GEOTECHNICAL RECOMMENDATIONS AND COMMENTS We understand that the seismic retrofit of the bridge is being designed to resist an earthquake event with a probability of occurrence of 10% in 50 years (1:475-year event). Further, the fundamental period of the bridge is expected to fall between 0.5 s and 1 s. In support of the seismic retrofit, provided below is a discussion on seismic site classification and an assessment of liquefaction triggering and post-liquefaction settlement and bearing resistance for Piers 2 and 3 that are pile supported. For the bridge abutments and Pier 1, our recommendations include dynamic shear moduli values for assessment of soil-structure interaction. 3.1 Seismic Considerations and Liquefaction Susceptibility The bridge abutments are supported on shallow footings that bear on rock. In the absence of site specific characterisation of the bedrock unit, Site Class C can be conservatively assumed. From the Natural Resources Canada website, the 2015 National Building of Canada Seismic Hazard Calculator provides a Firm Ground Peak Ground Acceleration (PGA) of 0.235g for the 1:475 year return period earthquake at this location. For Pier 1 that is supported by a shallow foundation bearing on rock or potentially on granular fill, Site Class C can also be assumed. At Piers 2 and 3, the penetration resistance measured during BPT profiling suggests that the cohesionless soils below the water table, at about a depth of 4 m (2.8 m below base of pile cap),


will likely liquefy. From Table 4.1 of the Canadian Highway Bridge Design Code (S6-14), this corresponds to a Site Class F. As mentioned earlier, the foundations supporting Piers 2 and 3 comprise precast concrete piles that were driven to bedrock and primarily derive their axial compressive resistance from end bearing. There is a possibility, however, that the piles were spliced which may govern the axial compressive behaviour of the piles during an earthquake event. Splices, if present, will also affect the tensile and lateral resistance of the piles under static and seismic loading. In the event that the piles are not spliced or if the integrity of the splice is not comprised during and following an earthquake, the loss of shear strength in the liquefiable soil will not have an adverse effect on the performance of the piles. Further, the piles are not expected to experience significant settlement as the neutral plane lies near or below the expected zone of liquefaction. For this scenario, Site Class C may be assumed for assessment. If the splice is fully damaged in an earthquake event, the piles will no longer bear on rock and the pile cap will behave as a shallow footing bearing on soil. This will substantially reduce the bearing resistance of the foundation and will result in excessive settlement of the foundation system. Where the cohesionless soil below the water table liquefies, we recommend that a factored bearing resistance of 80 kPa be assumed below the pile cap. If vertical pile support is lost, we anticipate settlement will range between 500 mm and 750 mm below the pile cap as a result of volumetric and shear strain settlements. The estimated settlement range represents a reasonable worst-case scenario that was evaluated assuming a 3 m liquefiable layer, up to 10% of post-liquefaction volumetric strain (this represents the anticipated behaviour of very loose material), a residual shear strength of 3.5 kPa (residual strength ratio of 0.05) and a post-liquefaction stiffness of 350 kPa for the evaluation of shear settlement (this represents the anticipated lower estimated strength and stiffness for very loose saturated soils), and no densification below the pile cap as a result of pile driving (see discussion below). Considering the relatively flat ground surface, lateral spreading is considered unlikely. While BPT profiling indicates that the cohesionless soils are very loose and are likely to liquefy below the water table, the results do not represent the state of the soils within and adjacent to the pile group that have experienced some degree of densification during pile driving. If a supplemental investigation were completed to quantify the degree of densification, a reduction in the estimated post-seismic settlement could be justified. 3.2 Input for Analysis

Dynamic Shear Moduli Values In support of soil-foundation-structure interaction modelling, dynamic shear moduli (G) values are provided in Table 1 below for evaluation of the compliance springs for the bridge abutments and Pier 1 footings.

The shear modulus values are based on PGA of 0.235g, assumed shear wave velocity values of 760 m/s and 450 m/s and unit weight values of about 22 kN/m3 and 18 kN/m3 at the abutments and Pier 1, respectively.

Depth-to-Fixity A lateral pile analysis was completed to evaluate the depth-to-fixity using LPILE software by Ensoft Inc., version 2016.9.10, which uses a series of discrete, non-linear springs referred to as the p-y curves to simulate the soil-pile interaction. The pile modelled in LPILE was 508 mm diameter, 11.5 m long round concrete pile with eight, 25 M bars of steel reinforcement (LPILE software does not provide an option to model reinforced octagonal piles). As the pile cap is expected to restrict the rotation of the pile heads, a fixed-head condition was assumed in the analysis. Table 1 below summarizes the soil parameters and soil spring models selected for the lateral pile analysis.

The results of the analysis suggest that the depth-to-fixity will be approximately 7.5 m for static loading conditions provided that the unfactored horizontal loads are less than 300 kN and the lateral pile response is not compromised by the presence of the splice. Where the lateral pile response is limited to the depth of the splice, then the splice should be modelled as a pinned connection. 4. POTENTIAL FUTURE GEOTECHNICAL INVESTIGATION If verification of densification of the soil from pile driving is required, we envisage the geotechnical investigation to comprise shallow test holes, advanced to the top of the clay unit, and cone penetration test (CPT) profiling to refusal. The investigation will require the use of a hydro-excavation truck to expose some of the exterior piles, to establish the pile group pattern and select test hole locations, and coring equipment to core through the pile cap at the proposed locations. Completion of the above investigation is recommended if a site-specific seismic response analysis is required in support of seismic design (i.e. analysis of pile response to kinematic and inertial loadings). The investigation, however, will not be able to confirm presence or condition of pile splices and as such will not be able resolve the uncertainty around the performance of the piles (see Section 3.1).

5. INTERPRETATION OF THE REPORT

a) Nature and Exactness of Soil and Contaminant Description: Classification and identification of soils, rocks, geological units, contaminant materials and quantities have been based on investigations performed in accordance with the standards set out in Paragraph 1. Classification and identification of these factors are judgmental in nature. Comprehensive sampling and testing programs implemented with the appropriate equipment by experienced personnel may fail to locate some conditions. All investigations utilizing the standards of Paragraph 1 will involve an inherent risk that some conditions will not be detected and all documents or records summarizing such investigations will be based on assumptions of what exists between the actual points sampled. Actual conditions may vary significantly between the points investigated and the Client and all other persons making use of such documents or records with our express written consent should be aware of this risk and the Report is delivered subject to the express condition that such risk is accepted by the Client and such other persons. Some conditions are subject to change over time and those making use of the Report should be aware of this possibility and understand that the Report only presents the conditions at the sampled points at the time of sampling. If special concerns exist, or the Client has special considerations or requirements, the Client should disclose them so that additional or special investigations may be undertaken which would not otherwise be within the scope of investigations made for the purposes of the Report.

b) Reliance on Provided Information: The evaluation and conclusions contained in the Report have been prepared on the basis of conditions in evidence at the time of site inspections and on the basis of information provided to Thurber. Thurber has relied in good faith upon representations, information and instructions provided by the Client and others concerning the site. Accordingly, Thurber does not accept responsibility for any deficiency, misstatement or inaccuracy contained in the Report as a result of misstatements, omissions, misrepresentations, or fraudulent acts of the Client or other persons providing information relied on by Thurber. Thurber is entitled to rely on such representations, information and instructions and is not required to carry out investigations to determine the truth or accuracy of such representations, information and instructions.

c) Design Services: The Report may form part of design and construction documents for information purposes even though it may have been issued prior to final design being completed. Thurber should be retained to review final design, project plans and related documents prior to construction to confirm that they are consistent with the intent of the Report. Any differences that may exist between the Report’s recommendations and the final design detailed in the contract documents should be reported to Thurber immediately so that Thurber can address potential conflicts.

d) Construction Services: During construction Thurber should be retained to provide field reviews. Field reviews consist of performing sufficient and timely observations of encountered conditions in order to confirm and document that the site conditions do not materially differ from those interpreted conditions considered in the preparation of the report. Adequate field reviews are necessary for Thurber to provide letters of assurance, in accordance with the requirements of many regulatory authorities.
