Design engineers and contractors both have a legal responsibility to provide a safe and healthy work-place on construction projects. One potential prob-lem with the traditional “design-bid-build” model is that it breeds a “cheaper is better” mentality among both design engineers and contractors. This leads to design engineers focused on specifying designs with the lowest initial cost to build it, and contractors that are focused on productivity on the jobsite. Also, this typically results in the low bidder of a tender being selected and increases the risk of compromising the quality of construction.

An unstable trench can collapse, killing or seriously injuring workers. One of the requirements under Ontario’s Occupational Health and Safety Act and Regulations for Construction Projects (OHSA O.Reg. 213/91) is to identify the types of soil and determine

Sewer pipes not only function as a conduit to transport stormwater or wastewater, but they must also have the load-carrying capacity for whatever is built above them. One fundamental difference between a rigid pipe like concrete, versus a flexible pipe like plastic or corrugated steel; is that a concrete pipe can be reinforced to accommodate any loading condition while the flexible pipe’s structural strength is provided by the pipe-soil interaction that must be properly constructed by the pipe installer. In other words, flexible pipe is much more installation sensitive because it relies completely on the soil envelope for its structural strength. continued on page 2

similar recommendations regarding the use of trench boxes. Here are a few highlights from these various sources:

• “When using movable trench supports, the pipe location, jointing, andits embedment shall be not disturbed. This can be accomplished bylimiting the use of standard movable trench boxes that are in excess of2.5 pipe diameters on either side of the pipe to below the top of thepipe or to a shelf above the top of the pipe.” – CSA B182.11, cl. 5.2.5.2

• “Movable supports should not be used below the top of the pipe zoneunless approved methods are used for maintaining the integrity ofembedment material. Before moving supports, place and compact embedment to sufficient depths to ensure protection of the pipe. As supports are moved, finish placing and compacting embedment.” –ASTM D2321, cl. 6.4.2

• “In order to use the shield with PE pipe, all excavation of the trenchbelow the pipe crown elevation should be done from inside of the shield. That is, the backhoe operator should dig inside of the shield and force the shield down as soil is removed. (The technique of digging out a large hole to pipe invert grade then sliding the shield into it will result in excess deflection of PE pipe and therefore, should not be used.) After placing the pipe in the trench, embedment material should be placed in lifts and the shield vertically raised after each lift is placed so that workers can shovel embedment material under the shield to fill the void created by the shield wall.” – PPI Handbook of PE Pipe

It would be very interesting to see how these last two points could be accomplished while observing the OHSA requirements because they require the worker to be inside the trench box while it is being moved, or the worker must enter an excavation that is no longer being protected by a trench box.

Conclusion

Based on these recommendations by the plastic pipe industry, the best case scenario for a plastic pipe would be installation in a Type 1 soil con-dition using a trench box designed to sit on a ledge 900mm above the trench bottom. Accounting for the minimum 150mm bedding below the pipe and the embedment extending a minimum 300mm above the pipe as per Ontario Provincial Standards; the maximum pipe size that works for this configuration is a 450mm diameter plastic pipe. Again this is the best case scenario for a situation requiring a trench box.

Proper construction practices with trench boxes that adhere to OHSA requirements may conflict with the plastic pipe industry’s recommen-dations. Pipe designers should be aware that it’s not viable to properly install large plastic pipe (greater than 450mm) without compromising the pipe embedment or the Occupational Health and Safety Act. Hopefully it’s clear to everyone which one of these takes precedence; worker safety is paramount!

the methods to be used to protect workers from cave-ins. The soil type in which an excavation is made should be classified as defined in OHSA O.Reg. 213/91, s. 226 where there are four general types of soil: Type 1 or 2 – good, stable soils, Type 3 – fairly good soil, and Type 4 – poor soil that is very soft and unable to support itself. In a single trench, soil prop-erties can vary widely from top to bottom or along its length. Even hard, stable soil may contain faults in seams or layers that make it unstable when excavated. If an excavation contains more than one type of soil, the soil should be classified as the type with the highest number.

Three basic methods can protect workers against trench or excavation cave-ins:

• Sloping – cutting back the trench wall at an angle inclined away fromthe excavation as prescribed in OHSA O.Reg. 213/91, s. 234.

• Shoring – timber or hydraulic support systems for trench or excavationwalls to prevent movement of soils, underground utilities, roadways and

foundations.

• Prefabricated support systems such as trench boxes and shields.

It’s important to note that both shoring systems and trench boxes mustbe designed by a professional engineer.

Trench boxes

Trench boxes are only meant to protect workers by providing a tempo-rary safe working area for installing pipe. OHSA O.Reg. 213/91, s. 235 requires a trench box be designed for a specific location or project if the trench depth exceeds six metres or the trench width exceeds 3.6 metres. Similar to the OHSA requirements for sloping a trench wall, trench boxes are required to be placed directly on the trench bottom in Type 3 & 4 soil conditions. For Type 1 & 2 soil conditions only, some trench boxes could be designed to be hung-up to a maximum of 900mm (36 inches) from the bottom of the trench. However a 300mm (12 inch) wide ledge must be provided to support the trench box, plus doing this will significantly reduce the actual capacity (allowable depth) of the trench box.

Flexible Pipe Industry’s Recommendations

There are several references that design engineers specifying plastic pipe must know:

• CSA B182.11 – Standard Practice for the Installation of ThermoplasticDrain, Storm, and Sewer Pipe and Fittings

• ASTM D2321 – Standard Practice for Underground Installation of Thermoplastic Pipe for Sewers and Other Gravity-Flow Applications

• Plastic Pipe Institute Handbook of Polyethylene Pipe

• Uni-Bell Handbook of PVC Pipe

For many years Townline Road in Cambridge was an out of the way, seldom used rural road that was originally constructed in the early 1900’s. Today it has become a vital artery for traffic movement north and south from Highway 401 on the eastern edge of this growing community in the Region of Waterloo. With extensive housing developments encroaching from the west and major arteries of Franklin Boulevard and Hespeler Road already congested in central Cambridge, Townline Road is fast becoming a favorite route for many local residents to move north and south from Highway 401 to their homes and businesses in Cambridge and the surrounding areas of Brantford, Hamilton and Guelph.

The increase in traffic on the deteriorating southerly portion of Townline Road did not go unnoticed and in the year 2004 the Region of Waterloo selected a consulting engineer AECOM from Kitchener, Ontario to be the project manager for the infrastructure renewal project. With a consult-ing firm in place, the Environmental Assessment and submission could begin and by the end of 2008 the review was completed. The next year and a half would focus on design and in the fall of 2010 the tender for the contract for the Reconstruction of Townline Road was awarded to local contractor Bel Air Excavating and Grading Ltd.

This 2.8 km piece of rural road to be reconstructed with storm and sani-tary sewer upgrades along with watermain installation was not however your typical road reconstruction. Townline Road is a unique area with environmentally sensitive bog locations, high water table and subsurface bedrock making the task at hand for Bel Air Excavating and Grading Ltd. very challenging.

For the Region of Waterloo and AECOM, one of the bog areas surround-ing Townline Road, known as the Portuguese Bog, would require exten-sive remediation to allow for the equalization of water flow beneath the reconstructed roadway. As Duncaun McLeod P.Eng., Manager of Com-munity Infrastructure Central Region for AECOM stated, “the reconstruc-tion of this portion of Townline Road will allow us to raise the freeboard of the roadway surface to adequately manage water levels in an area that for many years during heavy rainfall events or even the annual spring thaw would become susceptible to localized flooding.”

For service life, capacity considerations and road design limitations, the two small corrugated steel pipes currently in place were to be removed and replaced with a quad cell 2400mm x 1200mm precast concrete box culvert supplied by local producer M-Con Pipe and Products Inc. from Ayr, Ontario. With a minor increase in the road elevation coupled with the large waterway area of the quad cell box culvert, the equalization of the Portuguese Bog water levels will be realized ensuring localized flooding in this area would all but be eliminated. The project management team at AECOM led by Duncaun MacLeod, P.Eng. suggested, “the quad culvert design was selected over other alternatives because of the width and height restrictions the roadway design presented to us as well as the

volume of water the bog contained. As a result the quad cell box culvert installation became the most practical and cost effective solution to fulfill the one hundred year storm design.”

From a construction standpoint, discussions with Senior Estimator and Project Manager Jim Hendricks, C.E.T. of Bel Air Excavating highlighted the difficult situation the location for the box culvert installation pre-sented; “For us the preparation and dewatering of the area was the most challenging. Although the 100 metres of tight sheeting installed on either

side of Townline Road cut off the bog to the installation area, the dewa-tering and excavation of the peat material was quite extensive. Yet once we uncovered suitable native material and the area was readied, the box culvert installation was very straight forward.” When asked on how the installation proceeded from a project management perspective once the culvert location was controlled, Mr. McLeod remarked, “the installation went quite well considering the winter conditions, with all four cells totalling 114 metres installed and backfilled over a two day period.”

Road reconstruction, no matter what the circumstances, will always be challenging. For the Region of Waterloo and AECOM, the successful and cost effective reconstruction of Townline Road will be aided by the precast concrete quad cell box culvert installation. Although the cost and construction challenges of the installation cannot be underestimated, the result is an engineered structure that has reduced the risk of local-ized flooding in the area ensuring safe and dependable travel along this vital eastern artery with the Cambridge community for many decades to come.

PVC Pipe Removed from Durham Region Approved Manufacturers’ Products List

PVC pipe produced in accordance with CSA-B182.4 Profile PVC Sewer Pipe and Fittings has been removed from the Approved Manufacturers’ Products List of Durham Region, Ontario Canada. Reasons cited include:

• Poor pipe performance in places of poor compaction or improperbedding

• Difficulty in obtaining fittings

• Saddles could not be used to make connections due to the designof the outer pipe wall

• Difficulty when cutting in new connections into an existing pipe.

No one likes a drippy faucet at home, so why should a drippy pipe under-ground be any different? Municipalities in Ontario are paying far greater attention to the state of their sewers. The cliché, “out of sight, out of mind” is not an accepted practice anymore.

There are several reasons why a sewer pipe with a leak is not desirable.

PURPOSE: The obvious...it’s not what the owner paid for. A leak in a sewer pipe is an opportunity for groundwater to infiltrate into the sewer system, or, for sewer flow to exfiltrate from the pipe into the ground. A quality pipe with watertight joints will provide the desired performance. Reinforced concrete pipe (RCP) provides watertight performance by using rubber gaskets in its joints.

Should Someone Call a Plumber?

COST: Leaky sewers cost money. Extraneous flows that infiltrate into a sanitary sewer system translate into unbudgeted costs to treat additional sewage volumes at the wastewater treatment plant. The unexpected flows also take away from needed sewer capacities designed for future municipal growth. York Region is currently revamping its guideline for the commissioning of new sanitary sewers. It will implement best practices with the goal to reduce infiltration, one of two contributors to a sewer system wide problem called Inflow & Infiltration (I/I).

HEALTH: A very real concern is the possibility of a leak from a sanitary pipe into local groundwater used for drinking purposes. Municipalities in Ontario have been exercising best practices for years by citing MOE’s Design Guidelines for Sewage Works. For inhabited areas that rely heavily on groundwater for drinking water sources, one cannot afford the risk of contaminating subsurface drinking water reservoirs and groundwater well sources.

STRUCTURAL: Where there is movement of groundwater and voids present within a pipe’s supporting soil, a loss of pipe support can occur. It is the result of fines that can migrate to and from the embedment zone around the pipe. This is very probable if clear stone is used to support or backfill the pipe. Another opportunity for the migration of fines is infiltra-tion through a leaky pipe. Either way, a loss of support will lead to severe pipe distortion and/or structural failure of the pipe. Similarly, the article in this edition regarding the Sudbury library looked at the effects of a corroded CSP sewer whose leaky joints assisted in the migration of fines in the proximity of the building’s foundation.

For the reasons stated, it is unclear why a lower standard of joint performance or lack of a certification program for pipe would ever be used. If the intent is to have infiltration, then use products that are specifically designed to infiltrate groundwater at controlled rates.

The hydrostatic performance of RCP is verified by tests done at the manufacturing plant according to the Plant Prequalification Program (PPP). The PPP ensures RCP will meet the hydrostatic requirements specified in CSA A257.2 for concrete pipe with rubber gasket joints. Certification under the PPP then provides the engineer the assurance that a watertight and certified concrete pipe product is on site.

The PPP was first established in 1965 by Ontario Water Resources Commission (OWRC) and OCPA, and has evolved with different regulating bodies, including the Ministry of Environment, and the Ontario Clean Water Agency. Today, the PPP utilizes an Advisory Committee represented by: Municipal Engineers Association (MEA), Ministry of Transportation (MTO), Ontario Provincial Standards (OPS), Concrete Precasters Association of Ontario (CPA), and the OCPA. The Advisory Committee is responsible for administering the PPP and in turn used to prequalify plants, manufacturers and products of the precast concrete drainage products industry.

Hydrostatic testing of concrete pipe under the PPP includes the following parts:

1. Test assembly includes three different pipe setups, consisting of three pipe in-line with gaskets,

a. Straight alignment;

b. Deflected joints to simulate pipe misalignment in the field;

c. Pipe with Differential Load to simulate loss of support for the pipe length in the field.

2. Test pressure is 103 kPa (15 psi), with reduced pressures for the Deflected Test and the Differential Load Test.

3. Frequency of testing is a minimum of once every six months, with con- ditions based on quantity of pipe produced, and/or last production date.

4. A successful pass is given when there is no visible leak of water fromthe joint area or through the pipe wall, while under the hydrostatic test pressure for a 10 minute duration.

5. A failure in a test requires retesting of pipe within the same productionrun, with the new requirement of two successful tests for every single test that has failed. A continued failure of pipe will require all pipes in the production run to be segregated.

6. Note: Hydrostatic testing is also done for 1200mm diameter precast maintenance holes in a vertical setup.

Further details of the hydrostatic test or the PPP can be accessed via the “Technical Resource Centre” link found on OCPA’s website, www.ocpa.com.

Does all this guarantee zero leaks in a pipe sewer? Not quite. One must compliment pipe quality with a good installation. A quality installation of pipe will provide the necessary support for the pipe and help assist the joint to perform as expected (i.e. to be watertight). A quality installation includes a prepared base, compacted granular material that uniformly beds (supports) the pipe, and a permitted backfill material that is com-pacted around the remaining pipe. It also includes the proper placement and seating of the rubber gasket on a clean, undamaged joint. Lastly, an adequate amount of time allocated to field inspection will help ensure the pipe installation is done correctly. Together, product quality and installa-tion quality will improve pipe performance, and help mitigate the occur-rences of leaks sometimes seen in new sewer construction.

Deficient Drainage System Leads to Demolition of Sudbury Library

The South Branch of the Greater Sudbury Public Library closed abruptly on a Friday afternoon in March 2009 due to structural concerns as a result of settlement of the foundation. A librarian turned people away at the entrance. “How long will you be closed?” the people asked. “Forever,” said the librarian. Then she locked the door. The library was built in late 1988 to early 1989. One year after the South Branch’s sudden closing, the 20-year old library building was demolished. It was gone in one day and all the rubble was carted away. A new library will be built at a cost to the City of Greater Sudbury of $4.8 million.

After the library was closed, the city hired experts who determined the cause and extent of the building’s structural damage. Geotechnical Investigation by a Consulting Geotechnical Engineer dated June 2, 2009 offered the following explanations:

“A monitoring program was initiated to measure the apparent building settlements ... The surveying results indicated that the current building had undergone a differential settlement in the range of 380mm between the opposite ends of the building (down-ward movement measured at the north west corner). The measurement suggests that the existing building had experienced some recent accelerated settlement. Evidence of this movement was apparent by walking on the main floor of the Public Library and as noted by staff.”

The report went on to conclude:

Most Probable Recent Cause of Settlement:

• The relatively recent accelerated settlement movement was likely caused by the influx of storm water originating from the broken storm sewer and manhole connec- tion located near the northwest corner of the property. The mechanism of this failure would have resulted from the flow of the storm sewer water through the sand and gravel fill material causing internal erosion by transporting the finer sand and gravel sized particles into the voids of the underlying rock fill materials (voids in the range of 20% to 30% depending on the size of rock). The internal erosion would have caused voids within the upper foundation material (i.e. the sand and gravel fill) resulting in decreased bearing support. As the fines continued to be transported, larger voids in the form of channels would have been created which would have caused the movement of materials which resulted in the additional recent founda- tion settlements.

• The location of the corroded storm sewer pipe resulting in an influx of storm watermovement within the soil matrix for an unknown period of time also coincides with the location of where the building has experienced the largest differential settlement movement (380 mm) as monitored by Del Bosco Surveying and interpreted by J. L Richards.

An inspection video obtained by the Ontario Concrete Pipe Association under The Freedom of Information and Protection of Privacy Act clearly shows holes in sections of the wall of the corrugated steel pipe storm sewer due to rusting.

Engineers responsible for designing, constructing, and inspecting drainage systems in accordance with the Ontario Building Code (OBC) should be aware that the OBC contains requirements for leakage testing of pipes used in a drainage system.

Section 7.3.6.2. Tests of Pipes in Drainage Systems states: “Every pipe in a drainage system, except an external leader or fixture outlet pipe, shall be capable of withstand-ing without leakage a water test, air test and final test.”

Section 7.3.6.4. Water Tests in Drain, Waste and Vent Systems states: “Where a water test is made, all joints shall be tested with a water column of not less than 3 m...the system or the section shall be kept filled with water for 15 min.”

Reinforced concrete pipe (RCP) and manholes produced in Ontario are tested in the concrete pipe plants to ensure that they meet the requirements of CSA A 257 Series, Standards for Circular Concrete Pipe and Manholes and the Ontario Building Code. The hydrostatic performance of RCP is verified by tests done at the manufacturing plant according to the Plant Prequalification Program (PPP). The PPP ensures RCP will meet the hydrostatic requirements specified in CSA A257.2 for concrete pipe with rubber gasket joints. Certification under the PPP then provides the engineer the as-surance that a quality, watertight and certified pipe product is on site.

The $4.8 million rebuilding plan will see the new library financed by a combination of borrowing and contributions from reserve and capital funds. With only $1.3 million available from dedicated reserves, about $3.5 million will come from debt financing, with the city borrowing from itself and repaying the money – with interest – over more than 20 years. Debt repayments will amount to $278,000 annually, with those funds coming from three sources: $112,000 from the existing operating budget, $110,000 in revenue from development charges and a $56,000 increase in property taxes.

Professor Saiedeh Razavi was of-ficially named the Chair in Heavy Construction at McMaster Univer-sity at an announcement recently held at the university. In atten-dance were representatives from many of the 13 regional construc-tion organizations that pledged more than $1.25 million over five years to establish the Chair, including the Ontario Concrete Pipe Association. The amount has been matched by the University.

Razavi, who starts in her posi-tion as Chair as of July 1, 2011 joins McMaster from Concordia University where she has been working as a postdoctoral fellow. She will hold an academic ap-pointment in the Department of Civil Engineering with instruction

responsibilities at the undergraduate and graduate levels, as well as with the McMaster-Mohawk Bachelor of Technology civil engineering tech-nology program.

Razavi brings considerable experience in large scale industrial construc-tion projects to the position. She also has a keen interest in sensing and

information technology for construction and infrastructure management, logistics, and transportation. She earned her PhD in civil engineering from the University of Waterloo, M.Sc. in computer engineering (artificial intelligence) at Iran University of Science and Technology, and B.Sc. in software engineering at Sharif University of Technology.

Razavi said her goal is to build an “industry-grounded research agenda” and she pursued the McMaster post because of the university’s commit-ment to research, innovation and teaching.

She is the daughter of an engineer father and an artist mother and says the two influences have guided a “passion for seeing how innovation can change how people do things in construction.”

The Chair in Heavy Construction was established to provide leadership in advancing innovation in the heavy-construction sector, attracting and developing talent, and contributing to the advancement of a modern, durable and sustainable infrastructure in Ontario. An advisory team from the heavy construction industry will be assembled by the Chair to advise on priorities in these areas.

Engineering dean David Wilkinson said he doesn’t know of another chair on campus with such broad support of industry. That list includes individual companies and associations representing heavy construction, road builders and sewer and water main contractors and the Ontario Ministry of Transportation.

“It’s a remarkable group that represents well over 100 companies and also includes two labour unions … and the Ontario government,” said Wilkinson.

Munro Concrete Products Ltd. recently changed their name to Munro Ltd. This name change was made to reflect the company’s addition of new product lines and complimentary services outside the traditional gravity products area. Munro Ltd. continues to produce a full line of storm and sanitary products—including reinforced concrete pipe, main-tenance holes, catch basins, culverts and utility chambers—but they are now also a full supplier of fresh water transmission pipe (prestressed concrete cylinder pipe) and fittings, as well as a manufacturer of steel pipe and fittings for mechanical applications. Munro Ltd. has just com-pleted their fourth plant expansion and has 60,000 sq ft of floor space for engineered precast products. Engineered precast products include large structures, such as Munro Span, bridge superstructure and sub-structure components, box culverts, valve chambers, tunnel segments and railway ties. All of these precast structures are made inside the Munro facility under controlled conditions.

The name change also reflects Munro Ltd.’s expanding capabilities for providing project support services. Several years ago, Munro Ltd. invested in the development of an engineering team to complement and follow through on the design work done by consulting engineering companies. Now Munro’s engineering team can design various large structures such as valve, meter, utility and pumping chambers either as single or multiple sections assembled easily on site. The ability to pro-duce these large structures inside Munro’s manufacturing facility means that many more cast in place structures can be replaced with precast structures. This means faster installation and assured final product quality. Munro also provides field services including on-site welding, installa-tion assistance and engineered solutions to on-site problems. Munro Ltd.’s new website address is munroltd.com. The company is currently updating all printed and electronic materials to reflect the new name and product lines.

Munro Concrete Products Ltd. is now Munro Ltd.
