Provincial Trunk Highway (PTH)

Provincial Road (PR)

By Erin Anseeuw, C.E.T Lafarge

Paul Imm, P.Eng OCPA

Stories of motorists having near misses from sudden culvert failures and sinkholes within our highway infrastructure system have increasingly gained the attention of Canadians. As provinces already struggle to keep up with existing infrastructure that is reaching a 100 year service life, the premature failure of culverts that are in some cases less than 25 years old, will continue to hinder the ability for all levels of government to balance their budgets. Alternative pipe materials chosen strictly on low initial cost instead of long-term risk assessments is not only resulting in enormous emergency culvert replacement costs, but the unplanned closure of a highway also poses economic losses for all users who depend on a reliable highway system, not to mention the serious risk to public safety when these culverts fail with little warning.

The highways department in Manitoba, Manitoba Infrastructure and Transportation (MIT), recognizes that concrete pipe is a structurally engineered product with a proven service life of 70 to 100 years. The MIT Culvert Design Specification outlines what type of pipe materials can be used as a culvert under its provincial highways. This process is based on the highway classification such as Provincial Trunk Highway, Provincial Road, etc.; type of pavement structure such as concrete, asphalt or gravel; and the Average Daily Traffic (ADT) volumes.

Based on the MIT culvert selection criteria excerpted in the following tables, concrete pipe is the only pipe material allowed under any provincial highway with high traffic volumes.

Trenchless Concrete Culvert InstallationsTrenchless technologies such as pipe jacking are an attractive method of installing culverts because a new pipe can be installed quickly, cost effectively, and with minimal disturbance to highway traffic and the surrounding ecosystem. The basic method of pipe jacking is similar for all pipeline applications, however the method of excavating, or boring, through the earth horizontally immediately in front of the pipe jacking operation can vary depending on the pipe size, length of pipe run, and existing ground conditions. Also, the accuracy of alignment and grade required for a gravity flow system is typically maintained by a laser guided system.

Horizontal excavation methods can range from manual excavation by workers inside large diameter installations to micro-tunnelling boring machines that can be steered remotely from the safety of a control room at the surface. The method generally follows a repetitive sequence of excavation at the face, pushing the concrete pipe into the excavated cavity with hydraulic jacks, and removing the spoil by muck cart on rails, augers, or liquefying the soil to pump it out. Unlike deep sewer installations, culverts are typically jacked through an embankment so a framework of steel or concrete must be constructed to provide a means to resist the horizontal thrust of the jacks.

Rigid pipe, such as concrete pipe, is more robust and well suited not only to the high axial forces of jacking but can also accommodate the unpredictable variables that may be encountered along the entire length of an installation. Concrete pipe manufactured specifically for the axial and transverse forces from the jacking method is available in a range of sizes and can be used in a wide range of ground conditions. The Indirect Design method for determining the strength class of concrete pipe installed by jacking can be done with the computer design program PIPEPAC, while the design software PIPECAR can determine the reinforcing steel requirements under the ASCE Direct Design method (ASCE 27-00).

Highway 11 in North Bay was closed on Friday April 19th. 2013. The closure lasted for a day and a half.

The first report of problems was received shortly after 3 a.m., and the Ministry of Transportation had closed the road before 3:30 a.m. According

Culvert Failure Leads to Closure of Highway 11

Formation of the Centre for Advancement of Trenchless Technologies (CATT) at the University of Waterloo and the Regional Chapters that represent 10 Canadian Provinces in the North American Society for Trenchless Technology (NASTT) is also recognition that pipe jacking will become a large part of pipeline installation in the future.

Culvert Replacements in ManitobaDuring the period between August 2011 to June 2013 MIT issued a total of 16 tenders for the replacement of existing corrugated steel culverts under Provincial highways with concrete pipe installed by jacking, instead of the traditional open cut method. The 16 tenders by MIT included the installation of 118 new concrete culverts by the jacking method adjacent to an existing CSP which would then be abandoned and completely filled with concrete. Pipe sizes of the new concrete culverts in these MIT tenders ranged between 750mm to 2100mm for a total length of 4.4 km.

One sudden failure of a culvert occurred in Manitoba on May 8, 2013 when an 1100mm CSP culvert collapsed 20km west of Falcon Lake on Provincial Trunk Highway (PTH) 1. The CSP corroded at the invert and lost its surrounding embedment soil resulting in a sinkhole in the paved shoulder. The sinkhole presented a severe safety hazard to users of the highway and required immediate attention. Based on the classification of this roadway, MIT followed the Culvert Design Specification, and replaced the failed pipe with a 1200mm precast concrete pipe.

In addition to using concrete pipe, which was supplied by Lafarge Canada Inc., MIT engaged a local contractor to install the new culvert by using the jacking method next to the failed CSP culvert. To provide stability to the highway pavement above, the decommissioned CSP culvert was plugged using concrete. The local contractor used an Akkerman Tunnel Boring Machine (TBM) to jack the concrete pipe.

Contact the Ontario Concrete Pipe Association at [email protected], or your local concrete pipe manufacturer for more information on concrete jacking pipe, or the jacking method of installation.

to media reports, the Ministry of Transportation blamed the sinkhole on “a large culvert failure.” By 6 a.m. the sinkhole spanned one of the northbound lanes. By 10 a.m., it had extended into the southbound lanes.

At least one transport was damaged when the driver encountered the sinkhole. The truck driver, who was on his way with a load bound for Vancouver from Toronto, said his truck “went flying” when the sinkhole opened up below him, damaging the driver’s side front axle and tire of the rig. Neither he nor his passenger were injured in the incident. Their truck was pulled up on the side of the highway for repairs. The truck driver said another vehicle also hit the sinkhole before police and repair crews arrived on the scene, but that driver was able to continue.

Heavy rains moved in to the North Bay area on April 18, depositing 55 millimetres of rain in a 12-hour period. The high runoff volumes exceeded the culvert capacity. Ontario Concrete Pipe Association was informed that a disjointing problem with the corrugated steel culvert contributed to the mode of failure.

The area maintenance contractor replaced the existing steel culvert with a larger steel culvert.

The old British phrase probably sums it up best: ‘Penny wise, pound foolish.’ And so it is with traditional design-bid-build procurement methods for infrastructure projects. Sure, we save a small amount of money up front, but if life expectancy and life cycle cost aren’t factored into the equation, it can end up costing far more in the long run.

Costs for emergency repairs; costs for increased maintenance; it can even cost public works employees their jobs, or elected officials their seats in the next election.

For the public, underground infrastructure – water supply and sewer systems – is often a case of ‘out-of-sight, out-of-mind’. Until it fails; when the watermain bursts and there’s a boil water order and the streets are flooded; or a steel culvert collapses and cars fall into a sinkhole, as happened on Hwy 174 near Ottawa, Ontario in September 2012.

Yes, sometimes investigations and engineering reports are prepared. But those reports are not easy for the public to understand. They know little about materials selection and system design. They just know they’re increasingly falling victim to failing infrastructure.

Those of us in the industry know that materials and design receive the majority share of the accolades, or blame, for a project’s performance throughout its life cycle. Yes, installation quality is important, and all assets will require some regular maintenance, that, if left undone, can accelerate deterioration. But materials also matter. When the steel culvert in Ottawa collapsed, it was replaced with 3000 mm diameter 100D reinforced concrete pipe – in an emergency repair that cost over $5 million. Imagine the savings if reinforced concrete pipe had been selected from the beginning. There likely wouldn’t have been a culvert collapse causing a gaping hole in the highway which swallowed a driver and his car. Reinforced concrete pipe is a rigid pipe system that relies mostly on the strength of the pipe and is only slightly dependent on the strength derived from the soil envelope. The opposite is true for a steel culvert.

Why design-bid-build doesn’t workIt’s completely structured around lowest-first-cost procurement. The infrastructure owner releases a tender for design of a system. The engineering firm that bids the lowest price wins the contract. When the design is

complete, a tender is issued for construction. The contractor who bids the lowest price to construct gets to build.

Infrastructure products, like pipes, used on projects are pre-approved by the owner. Each type of pipe material, once approved, is treated equally in the process. So if plastic, steel, and concrete pipes are all permissible, the choice is left up to the contractor, who often opts for the cheapest and easiest to install. There is no consideration of life cycle cost.

This process does little to ensure the best value for taxpayers’ money in the long term. Nor does it create confidence that the best materials and methods are employed.

Risk is only being shifted with Public Private PartnershipsMany large infrastructure projects in Canada are now funded by a public private partnership (P3) model. Some are design-build-finance-maintain, which means the successful bidders (again based on lowest cost) must provide maintenance for the system for a period of time. But the maintenance period is usually much shorter than the infrastructure’s life cycle. For The Herb Gray Parkway, currently under construction in Windsor, Ontario, the maintenance period is 30 years – well below the expected life cycle of the bridges, roads and tunnels. The Ministry of Transportation Ontario will be maintaining the assets of the Herb Gray Parkway long after the consortium constructing it now has received their last payment.

In September 2012, Canada’s first national report card on the state of municipal infrastructure was released. The results were unsurprising.

First National Report Card on Canadian Infrastructure (Excerpt)Wastewater infrastructure• 40.3% of plants, pumping stations and storage tanks were in fair to very poor condition • 30.1% of pipes were in fair to very poor condition• Replacement cost: $39 billion

Drinking water infrastructure• 15.4% of drinking water pipes were in fair to poor condition • Replacement cost: $25.9 billion

Stormwater management:• 12.5% of the stormwater installations surveyed fall below good condition • 23.4% of the stormwater pipes fall below good condition• Replacement cost: $15.8 billion

The total replacement cost to upgrade all of these linear assets is $80.7 billion – $6,488 per Canadian household.

We need to start examining what materials and processes we use to construct or rehabilitate our infrastructure.

All infrastructure product materials are not created equal when we consider longevity and life cycle cost. If they were, the steel culvert that collapsed and caused the Ottawa sinkhole would have been replaced with another steel culvert, because they’re still less expensive than reinforced concrete pipe. But those who made the decision to purchase the replacement materials knew that reinforced concrete pipe was a better, longer-lasting material. Safety and longevity governed, not low initial cost, but that decision should have been made at the start.

Designers Need to do More Than Reference a Standard

Gerrard F. Mulhern, P.Eng OCPA, Executive Director

On a regular basis, the professional engineers at Ontario Concrete Pipe Association are presented with specifications for drainage systems that do little more than reference a national or provincial manufacturing standard for a particular type of pipe. Typically in Ontario, the referenced standards are developed by the Canadian Standards Association or Ontario Provincial Standards. Design engineers charged with designing our province’s infrastructure need to do more than just reference a standard.Specifically for drainage systems and sanitary sewers, designers need to recognize that successful projects demand three key elements:

• Quality pipe

• Sound engineering and design

• Proper installation and post installation inspection

In order to achieve this, comprehensive specifications are required that address all three elements regardless of the pipe material or pipe system that is being used. For the purpose of this article the designer is urged to consider the following information and disclaimer from Canadian Stan-dards Association (CSA).

The Canadian Standards Association is a not-for-profit, membership-based association serving business, industry, government and consumers in Canada and the global marketplace.

CSA standards are developed through a consensus development process approved by the Standards Council of Canada. This process brings together volunteers representing varied viewpoints and interests to achieve agreement and develop a standard. Although CSA administers the process and establishes rules to promote fairness in achieving consensus, it does not independently test, evaluate, or verify the content of standards.1

The following Disclaimer and exclusion of liability is included in the standards developed by CSA:

“This document is provided without any representations, warranties, or conditions of any kind, express or implied, including, without limitation, implied warranties or conditions concerning this document’s fitness for a particular purpose or use, its merchantability, or its non-infringement of any third party’s intellectual property rights.

CSA is a private not-for-profit company that publishes voluntary standards and related documents. CSA has no power, nor does it undertake, to enforce compliance with the contents of the standards or other documents it publishes.”2

The user of such a standard, namely the design engineer, should beunder no illusion: The Canadian Standards Association or any similar body is NOT accepting any responsibility for his/her design.

The engineers at Ontario Concrete Pipe Association have over 60 years combined experience in the gravity pipe and precast industries. We make this experience available to designers and project managers through our Lunch and Learn program. We address the three essential elements listed above for successful drainage and sanitary sewer projects and provide recommendations to the designers to protect himself or herself from litigation.

Elliot Lake Mall Inspector Admits Omitting Details from Report

The engineer who declared the mall in Elliot Lake, Ontario, to be structurally sound weeks before a portion of its roof collapsed admitted to changing crucial details in the inspection report while testifying for a second day at an inquiry into last year’s collapse.

Bob Wood admitted that the Algo Centre Mall’s owner asked him to change or omit details about the condition of the mall from an inspection

report filed in 2012. Wood said he went along with the requested chang-es on a promise from the owner that the problems would get fixed.“I gullibly believed him,” said Wood.

He said he was asked to leave out details concerning a complex tarp system temporarily in place to deal with chronic leaking. He was also asked to leave out words such as “ongoing leakage” and “particular concern” as well as certain photos.

“Our inspection revealed evidence of rusting on the structural steel members where the parking deck was leaking,” Wood told the inquiry.

The report was changed, according to Wood, despite it already being signed-off by a senior engineer.

Wood stated that he stood by the 2009 inspection report he filed on the Mall.

He said he ignored a city order to inspect the entire mall for structural damage, instead focusing on a few areas identified as problematic.The inquiry heard complaints of the roof vibrating when vehicles drove across the mall parking lot. Mall employees told the commission they had expressed concern and former tenants believed that the structure would collapse.

Wood claimed he wasn’t concerned about this section of the parking deck at the time.

“We stood on the deck. We weren’t holding hands but we were standing there while vehicles went by and there was no indication of any problems,” said Wood.

Mall collapse – investigations and lawsuits

Addendum Addresses Standard of Care for Plastic Pipe

A sanitary sewer project was released for tender by the City of London in early 2013. The sanitary sewer was designed using reinforced concrete pipe. However, the contract also included a trial section of 65 metres of 900mm polypropylene plastic pipe. The plastic pipe in question was offered free of charge by the Ohio based producer of this pipe.

There are major differences between reinforced concrete pipe and plastic pipe. Drainage systems and sewer systems constructed from concrete pipe and plastic pipe have to be designed differently and installed differently. The consulting engineer for the City of London project recognized those differences and issued a comprehensive addendum to address the design and installation of a relatively large plastic pipe.

The key points of the Addendum included:

• Certification Letter from contractor – includes shop drawings, calculations, and installation procedures.

• Design calculations stamped by a professional engineer registered in the Province of Ontario.

• Trench box detail stamped by a professional engineer registered in the Province of Ontario addressing the potential conflict between ASTM D2321 and Occupational Health and Safety Act.

• Shop drawings for connection to manholes.

• Deflection testing at completion of construction and again at one year before the expiration of the warranty period.

• Manufacturer’s representative on-site during construction.

Design engineers and municipal engineers involved with drainage systems and sewer systems across Ontario should take note of the wording of the Addendum as follows:

“For the Pipe Trial Section pipe materials, the Contractor shall submit shop drawings.

The shop drawing submission shall include a Certification Letter from the pipe manufacturer that the pipe material and installation procedures will meet or exceed City of London Standard Specifications, these Special Provisions and the installation conditions shown on the drawings and as otherwise identified in the Contract Documents. The Contractor (or pipe supplier) shall provide the structural design calculations for this pipe installation, stamped by a professional Engineer licensed in Province of Ontario.

The Contractor shall submit drawings for the trench box use stamped by a Professional Engineer licensed in the Province of Ontario, which meets the requirements of both ASTM D2321 -Standard Practise for Underground Installation of Thermoplastic for Sewers and Other Gravity- Flow Applications and Occupational Health and Safety Act and Regulations for Construction Projects.

The Certification Letter shall be supported by detailed pipe class selection calculations and shall be sealed by an Ontario Professional Engineer, specifically for this project.

The Contractor shall provide a shop drawing identifying the two manhole connections. A cored hole shall be drilled to accommodate the manufacturers’ connection boot.

Sanitary sewers are to be installed as per manufacturer’s specification. The Contractor shall have on-site at the commencement of construction, a manufacturer representative to advise on the recommended construction procedure for the installation of sanitary sewer. The Contractor shall maintain liaison with the manufacturer throughout the installation of the sanitary sewer trial section for advice and guidance as required. In addition, the Contractor shall ensure that a representative of the manufacturer makes daily site visits during construction and after completion,if required. The representative of the manufacturer should alert the Contractor in writing of any variance to their recommended material and construction procedures. Copies of all correspondence shall be given to the Contract Administrator.

Where the trial pipe section is used, the Contractor shall perform a mandrel test, upon completion of construction, to ensure that pipe deflection does not exceed a 5% deflection. Prior to the end of the one-year warranty period, the Contractor shall perform another mandrel test, to the satisfaction of the Contract Administrator.”

science technicians and technologists in industry, educational institutions, the public and government.

OACETT was incorporated in 1962 and was legislated under the Statutes of Ontario by the OACETT Act of 1984. The Act recognizes OACETT as a professional body whose main objective is to establish and maintain high standards for the profession of Engineering/Applied Science Technology. In December 1998, the provincial legislature passed the OACETT Act of 1998. The revised act includes a description of work for technicians and technologists, giving members more recognition for the work they do.

OACETT is Ontario’s independent certifying body for engineering/applied science technicians and technologists. The certifying arm of OACETT is the Institute of Engineering Technology of Ontario (IETO). IETO’s panel of expert members evaluates applications and registers engineering/applied science technicians and technologists who meet recognized national standards in education and experience.

OACETT confers the designations C.Tech. (Certified Technician) and C.E.T. (Certified Engineering Technologist). These symbols of achievement in engineering/applied science technology are legally protected for use by certified members. The designations are recognized across Canada by employers and other engineering professionals.

Concrete Pipe Plant Tour with Sennheiser Tourguide System

OCPA Conducting Plant Tours with Sennheiser Tourguide System

Ontario Concrete Pipe Association is now pleased to be able to offer plant tours with the Sennheiser Tour Guide System. OCPA has conducted plant tours for many years at the concrete pipe and precast facilities operated by its member companies. Concrete pipe and precast plants can be noisy environments and sometimes the commentary during plants tours was not fully received as a result. With the SennheiserTourguide, every word will find its way to the listener.

Ontario Concrete Pipe Association members have manufacturing plants strategically located across Ontario from Cambridge to Ottawa and from Burlington to Sudbury. These plants manufacture a wide range of concrete pipe and precast products.

OCPA organizes plant tours through any of these plants for engineers, government officials, contractors or student groups.

Plants tours address:• Quality Control through the Plant Prequalification Program• Dry cast manufacturing• Wet cast manufacturing• Three edge bearing strength testing• Hydrostatic testing• Product examination

The 2013 OCPA Suppliers Golf Tournament was held at Galt Country Club in Cambridge on July 8th. There was an excellent turn out this year with representa-tion from producer members and supplier members. The course was challenging but all groups completed their rounds in just over four hours. The Preston Room at Galt Country Club facilities and service were excellent as usual. OCPA sponsored a reception and this was followed by dinner and awards.

The winning team was from Hamilton Kent with a score of minus 7.

The long drive was won by Vern Cameron from HawkeyePedershaab and closest to the pin was won by Dan Jean from Munro Ltd.

This year’s tournament was organized by Drew Black from JD Industrial Sales and Steve Zupko from Lafarge North America with assistance from Diane Mauro, Ontario Concrete Pipe Association.

The members and staff of Ontario Concrete Pipe Association are sincerely grateful for a very well organized day.

Thanks Diane, Drew and Steve!
