Innovative Reinforced ConcretePipe Drop Structure Used toConstruct Storm Water OutfallBy Albert Wissa, P.Eng., Niran Construction& Kent Campbell, Hanson Pipe & Products Canada, Inc.

Development of tableland, north of Sheppard Avenue andeast of Meadowvale Road in the Scarborough CommunityCouncil Area of the City of Toronto, has been planned forresidential use for decades. A major concern addressedthroughout the planning process for proposed develop-ments has always been the fragile nature of the steep bluffsdropping sharply to the Rouge River.

Mattamy (Rouge) Limited was one of the developments thatrequired approvals to discharge storm water to the RougeRiver. A storm water management pond had to be construct-ed on the tableland and a storm sewer outfall at the base ofthe steep valley slope. Storm water is collected and dis-charged into a storm water management pond. From there,the water drains to a 975 mm diameter concrete pipe outletand is conveyed by a 31.3-metre deep drop structure (900mm diameter) to the base of the slope.

M Con Products Inc. ExpandsOperations Into Southern OntarioBy Mark SabineSales Manager, M Con Pipe & Products Inc.

In April of 2004, the M Con Group ofCompanies expanded their Ottawa Valleyoperations into Southwestern Ontario whenthey broke ground on M Con Pipe andProducts Inc. in Ayr, Ontario. The familyowned operation started in the precast con-crete industry almost fifty years ago in theOttawa region. The Mion family, believedthat expansion into the vibrant southernOntario marketplace seemed to be the nextbest step in the positive growth of the organ-ization. With that decision made, a seventy-five-acre parcel of land was purchased in Ayr,a small community bordering the “GoldenHorseshoe” near Cambridge Ontario.

By September that same year, productionbegan in earnest at the 35,000 square foot

manufacturing facility. The production facilitythen went through the Plant PrequalificationProgram Certification to ensure compliancewith OPS requirements.

M Con Pipe and Products Inc. housesHawkeye production equipment and an MBKautomated cage welding machine. TheHawkeye system is a PipePlusPlus and VUPcombination which can produce pipe andmaintenance holes up to and including3600mmin diameter. As a sister operation toan Ottawa manufacturing facility, the twocompanies together offer a wide range of wetcast and dry cast products including the forementioned, as well as, box culverts, head-walls, valve chambers and barrier walls.

One of the newest production components theindustry has seen in recent years can befound at the Ayr facility. This system can besimply described as pumpcrete, a manufactur-ing process that pumps or injects concrete intoa form, venting the air through bleed holes inthe header. Pumpcrete allows for the manu-facture of products such as pre-benchedmonobases and barrier walls, however, thelimits of this new system are boundless.

Storm Water Outfall continued from page 1

much larger steel lined working shaft toaccommodate pipe and equipment. The con-struction cost would have been much higher.With an internal drop, the concern aboutcracks in the concrete drop structure wasalleviated and the cost of constructionreduced dramatically.

Construction of the maintenance shaft anddrop structure took two weeks as all compo-nents were precast concrete maintenancehole components. The entire shaft is madeaccessible by a combination of aluminumsafety platforms and steps built into the risersat the Hanson plant. When work reached theelevation where the inlet pipe from the pondentered the vertical drop shaft, a special tran-sition structure comprised of a weir andbenching was specially designed by theHanson engineering team. The challengewas to provide benching that did not causeturbulence of the storm water as it entered

the structure, and reduced the entrant coeffi-cient for the flow transitioning from the 975mm horizontal pipe to the 900 mm verticalpipe. Hanson engineers used a unit of ellipti-cal pipe with convex benching at the base asa reducer to direct the flow into the drop shaft.Once the transition structure including reduc-er and weir were in place, the contractor wasable to continue with the construction of astandard 1200 mm diameter maintenancehole to the surface.

Jacking the outfall pipe from the structure atthe bottom of the shaft, and construction ofthe headwall took 50 working days. Sincethe cylinders of the jacking machinerequired more space than was available inthe working shaft, the contractor built a 3-metre “tail tunnel” that extended beyond thecircumference of the working shaft. The tailtunnel accommodated the cylinders of thejacking equipment. Once the pipe jackingwas completed, the metal lined tunnel wascompletely filled and covered by steel wallplates. The jacking pipe was 1200 mmdiameter pipe supplied by Hanson.

The precast concrete drop structure isbelieved to be the deepest in Canada forcompleting a storm water management sys-tem for a residential development. Precastconcrete manhole components, and standardconcrete drainage and jacking pipe proved tobe an easily installed, economical, long-termsolution. The City of Toronto acquired anasset that adds long-term value to its massiveinventory of buried infrastructure, while con-tributing to the improvement of the quality ofstorm water entering its urban watersheds.

OCPA Golf Tournamentat Legends

The 3rd Annual Ontario Concrete PipeAssociation Suppliers Golf Tournament washeld on Monday June 20th at the beautifulLegends on the Niagara Battlefield Course.A total of thirty six golfers participated on thevery warm day, which was followed by agreat buffet dinner. The day ended with thepresentation of the prizes. A ‘scramble’ for-mat was used and the winning group for theday included George Biro (Stel-Crete), JimTully (Munro), Karl Hartl (Munro) and GaryDeppe (MCM Industrial). Congratulations tothe winners and to all those who participat-ed. The specialty prize for closest to the pinwas won by Robert Munro (Lafarge NorthAmerica), the longest drive for the men waswon by Mark Sabine (M-Con Pipe &Products Inc.) and the ladies’ was won bythe OCPA’s own Bernadette Manning. Manythanks as well to those members who con-tributed to the wonderful prize table. For asmall tournament, the selection at the tablewas excellent and ensured that everyonewho participated in the day would leave witha memento of the day. Thank you to all

those who participated and we look forwardto seeing everyone again next year.

Crack or Fracture?If you are responsible for InfrastructureAsset Management focusing on under-ground infrastructure condition assessmentand rehabilitation programs for water andsewer systems, then you have probablycome across the question of what a crack inconcrete pipe actually means. Concretepipe is designed to crack. In fact, the rein-forcing steel assumes virtually no load untilthe concrete cracks.

In order to properly assess the condition ofa sewer pipe, two factors have to be takeninto consideration:

11.. Internal Condition Grading, which is cal-culated using defect scores, filters out sew-ers with high probability of requiring repair.

22.. Structural Performance Grading, which isassigned by qualified individuals based onthe significance of observed defects andenvironmental factors on performance.

CCTV operators are responsible for produc-ing reports that reflect the current condition ofthe sewer pipe inspected and for properlycoding sewer pipe defects. To comply withOPSD 409.07.01, the CCTV operator shallbe certified by the NAAPI, and should betrained in the correct use of defect coding inaccordance with the NAAPI Manual of SewerCondition Classification. A pan and tilt cam-era system can provide superior view of pipebut at the same time it can magnify defects –making them appear larger and more severethan what they really are and operators must

Circumferential Crack rehabilitated throughAutogenous healing

understand the “process” to accuratelyassess the structure.

At a more technical level, the engineerresponsible for prioritizing work require-ments shall do an overall assessment of theinspection reports based on:

• Risk management – considering the prob-ability of failure and the consequences offailure.

• Risk mitigation – understanding when and where to invest in maintenance and reha-bilitation.

Ensuring quality inspections will allow you tomanage infrastructure capital assets to mini-mize the total cost of owning and operatingthem, while delivering the service level cus-tomers desire.

M Con ExpandsOne very busy year later, the Ayr plant isalready undergoing an expansion of 15,000square feet. This addition is essential forincreasing production floor area while at thesame time providing the necessary room forthe installation of a second MBK cagemachine capable of manufacturing steelcages for the production of larger diameterpipe and maintenance holes previouslymanufactured in the Ottawa operation.Furthermore, this expansion will also includethe clearing and preparation of another fiveacres necessary for storage of manufac-tured product and raw materials.

Once complete, the expansion will provide akey piece in the puzzle of market competi-

tion, providing economical production andshipping in conjunction with improved inven-tory levels which undeniably improves serv-ice and thus customer satisfaction.

With now more than thirty staff employed atthe Ayr manufacturing plant, production andservice staff alike are anxiously awaiting theexpansion conclusion. The decision to expandthe Ayr operation albeit sooner than forecast-ed could not have come at a better time. Thiscommitment by the Mion family has been awelcome show of faith in everyone involved inthe new operation. With the new tools in hand,the environment of self sufficiency and com-plete responsibility are challenges everyoneinvolved are grateful to tackle.
