ome of you may have noticed this by now, but just in case you missed it: I’m a girl! More specifically, I’m a girl in the construction industry, which has prompted many questions from the curious. I’m often asked: “How did you get into the business?” Was your Dad a contractor?” and, “Do stilettos come in steel toe?” I find these questions amusing. People want to get a handle on my “perspective.” Being a woman in what has traditionally been a “man’s industry” does not come without a few perks. For one, I have never had to wait in line for the ladies room at a tradeshow or conference. More significantly, I am often invited to take part in women-centric construction events. At first, I was apprehensive about this sort of attention. After all, good contractors are good contractors whether or not they stand up or sit down to pee. But through my connection with the Women in Construction (WINC) organization, I have discovered how powerful the so-called “weaker” sex can be, and now I wear my pink hardhat proudly. In just a few short years, WINC has raised more than $80,000 for Habitat for Humanity in Toronto. It was an honour to swing a hammer
along side these highly skilled ladies on May 9 at the recent Women’s Build. Although I am currently bestowing accolades on the fine ladies at WINC, I would be remiss if I didn’t point out that Canada’s construction industry, as a whole, does a phenomenal job at building better communities through financial and time investments. Nearly every one of the contractors you see listed in the Top Contractors report on page 17 have made significant investments in Habitat for Humanity, United Way, Canadian Cancer Society, Heart and Stroke Foundation, and the list goes on with a host of more specific local community projects. In conversations I had with this year’s top construction firms, it became clear that strong local community involvement is a cornerstone of successful construction businesses. Many of the biggest companies, such as Aecon, EllisDon and PCL are focusing more of their time and resources on supporting employee-driven initiatives rather than the larger-scale United Way-style campaigns that are popular with large corporations. We often credit the construction industry for literally building the roads, schools and structures in which we conduct our daily lives, but we must also recognize how our time and financial investments are building better communities.

SNC-Lavalin/Cintra awarded billion-dollar bid for 407 East Highway project The 407 East Development Group General Partnership (the Partnership), a 50/50 joint venture between Montreal, Que.-based SNC-Lavalin and Cintra Infraestructuras’ respective subsidiaries, was awarded a contract by the Province of Ontario to design, build, finance and maintain Phase 1 of the new Highway 407 East, valued at approximately $1 billion. The project will be delivered using Ontario’s alternative financing and procurement (AFP) delivery model. Phase 1 will create a 22-kilometre extension of the highway east from Brock Road in Pickering, Ont., to Harmony Road in Oshawa, Ont., as well as a 10-kilometre north-south highway, east of Lake Ridge Road, that will connect Highway 407 East to Highway 401. The project’s design and build portion is expected to take approximately three and a half years to complete. The Partnership also entered into a contract to maintain and rehabilitate the road for the next 30 years and has signed a fixed-price contract with a 50/50 consortium composed of SNC-Lavalin Operations and Maintenance and Cintra for the road’s maintenance and rehabilitation over the concession period.
Federal Government accepts recommendations on nuclear project The Government of Canada has accepted recommendations from a Federal Joint Review Panel on the nuclear project at the Darlington site in Clarington, Ont. The project will provide up to 60 years of base load electricity for the people of Ontario and will create significant employment for the construction trades and for Ontario’s manufacturing sector. The construction of new nuclear units at Darlington could result in more than 30,000 person years of direct employment including more
than 9,000 person years of employment in Ontario’s manufacturing sector. With the planned shutdown of all of Ontario’s coal generating plants by 2014 and the decommissioning of the older nuclear units at Pickering over the next 10 years, Ontario will require new reliable and economic base-load generation by 2022. The proposed new nuclear units at Darlington will form an integral part of Ontario’s electricity supply system—consistent with Ontario’s Long-Term Energy Plan that calls for continued reliance on nuclear power for 50 per cent of the province’s energy supply.

CONSTRUCTION STATS A selection of data reflecting trends in the Canadian construction industry
Composite price index for non-residential up in Q1 The composite price index for non-residential building construction increased one per cent in the first quarter of 2012, when compared to the previous quarter. The increase was largely due to continued strength within the construction sector, which resulted in higher prices for some construction materials, particularly in Western Canada. Out of the seven census metropolitan areas (CMAs) surveyed, Edmonton reported the highest quarterly increase at 1.7 per cent. Edmonton also led the year-over-year composite price index for non-residential building construction, with an increase of 4.6 per cent.
Building permits down in April Building permits fell 5.2 per cent to $6.5 billion in April 2012. The drop follows two consecutive monthly increases and was mainly due to lower construction intentions for institutional buildings and multi-family dwellings in Ontario. The non-residential sector experienced an 8.4-per cent decline to $2.7 billion with construction intentions down in six provinces; led mainly by Ontario. The value of building permits fell 43 per cent to $556 million in the institutional component, fuelled by a reduction in intentions for government buildings and medical facilities in Ontario. The commercial component experienced a 1.9-per cent increase to $1.6 billion in April for its third consecutive monthly increase. Alberta and British Columbia experienced the most significant boost; mainly due to increased construction intentions for office buildings. The industrial component increased by 34.7 per cent to $554 million, with eight provinces experiencing gains in construction intentions in April. Quebec led all provinces in the industrial component, largely due to an increase in building intentions for transportation buildings and manufacturing plants. Total building permits values fell in 19 out of 34 metropolitan areas with Toronto, Ont., St. John’s, Nfld., and Edmonton, Alta., experiencing the largest declines. The biggest increases were experienced in Calgary, Alta., and Montreal, Que.

Employment in the construction sector climbed by 25,000 in April, which led a gain of 58,000 jobs nationwide. Over the past 12 months, employment within the construction industry jumped 3.5 per cent. The majority of the 58,000 positions gained were full time, fuelled by increases throughout the goods sector—including construction, manufacturing, natural resources and agriculture. There were more people looking for work in April, raising the unemployment rate by 0.1 per cent to 7.3 per cent. Canada’s employment levels over the past 12 months increased by 1.2 per cent, or 214,000 jobs.

TOP Contractors The right stuff BY CORINNE LYNDS
t
here’s little doubt that after a few tough years, 2011 was a nice blip on the balance sheet for Canadian commercial contractors. In this year’s Top Contractors report, we take a closer look at what it takes to be a leader in the construction industry, what sectors are most promising for 2012-2013, and what challenges lay ahead. This report is based on direct research with private companies, with the addition of a small amount of data from public sources. It’s important to note the rankings are based on revenue, just one measurement in gauging a company’s performance. We thank these companies for sharing their information with such enthusiasm. Canada’s construction industry has an amazing story to tell, and their participation in this report helps get the message across. If you have any questions or comments about this report, or want a listings form for next year, please contact us at 416-510-6821 or editor@on-sitemag.com.

So, what does it take to be one of Canada’s top contractors?
R
unning a multi-billion dollar contracting business is not for the faint of heart. Financial, technical and even political challenges are business as usual for this select group of individuals; but at the end of the day, it’s a simple concept that’s keeping these companies at the top of On-Site’s annual Top 40 Contractors list. “It is a total commitment to serve the clients’ needs, all of our clients,” emphasizes Aecon president John Beck. “So what we have been doing is diversifying our capabilities by expanding geographically.” Aecon has been achieving this diversification through what Beck describes as “organic” expansion. In other words, following its clients and making sure that they have access to all the construction capabilities they need across Canada. In areas where appropriate, No. 2-ranked Aecon has accomplished this through acquisitions. Paul Douglas, president of No.1-ranked PCL, is also quick to credit a client-focused approach for his company’s long-term success. Roughly 90 per cent of PCL’s 3,600 salaried employees are owner/operators that represent the company across Canada with the same consistent code of conduct, ethics and culture that has been upheld by PCL since its inception in 1906. No. 3-ranked EllisDon believes its clients are best served by maintaining good relationships with trade contractors, suppliers, consultants, owners and labour forces.

“They always have to be able to look at you at the end of the day and know you are someone who will treat them fairly,” says Tim Smith, EllisDon’s senior vice-president, Toronto area. He explains that the company’s culture, which emphasizes project first and process to follow, is dependent upon these strong partnerships. “We understand our place in the whole development scheme, and that is as the catalyst to get the project up and completed; so the end user, whether it’s a hospital or a commercial developer, can get its tenants in. That’s our role. To get it up in good quality, in a good time frame that they can count on with some certainty on price.”
Savvy contractors have been aware of the impending labour shortage for some time and are already developing the next generation of skilled workers. Their initiatives include apprenticeship programs, recruiting co-op students, fast-tracking young managers and partnering with the labour unions and post-secondary institutions. However, skills development alone may not be enough. Aecon, EllisDon and PCL have differentiated themselves by finding other ways to attract highly skilled and ambitious young workers. Repeatedly gracing Canada’s Best 50 Employers list, these contractors understand that it takes more than a paycheck to retain good people. They offer salaried employees an opportunity to buy stock in the company, flexible hours and strong healthcare programs. They also create a corporate environment that promotes environmental sustainability and strong community/charity involvement. For example, Aecon offers a scholarship program to help support the education of its employees’ children. The hope for this initiative is that it will foster good will in those future graduates and they will consider Aecon when they are ready to join the workforce.
People first Culture and client focus are key, but without the right skilled trades people for the jobs, the construction sector could be in big trouble. Our top-three companies cited the impending skills shortage as one of the biggest challenges they are facing. As such, employee retention, succession planning and skills development programs are key areas of focus for the construction industry. “I talk to CEOs from Newfoundland through to Victoria and their biggest concern is having the skilled workers that they’re going to need to build what we want to build over the next decade,” says Douglas.
Foreign competition The looming skills shortage is not the only challenge tangling contractors sheets at night; uncertainty surrounding foreign competition is giving these steadfast executives due cause to toss and turn. “It’s good news and bad news,” sighs Beck. “First the bad news: We don’t want governments or even the private sector to consider working with companies that have no experience on the ground here in Canada.”

The good news, however, is that in order for foreign companies to gain the necessary experience, they need to partner with Canadian contractors. “We welcome those partners,” explains Beck. “In fact, we’re partnering with a lot of them today. We think they bring a lot of experience, skills and a different way of looking at things. And, sometimes they bring money in these public-private
partnerships—that’s all good, and that’s welcome.” Across the industry there’s some concern about inexperienced foreign firms coming in and winning projects, but Smith is quick to point out that no one wants a closed-border environment either. “We wouldn’t want to have that imposed on us if we were to go abroad.” And going abroad is exactly what PCL was recognized for when it picked up the International Business Award at the Canadian Construction Association’s annual conference back in March. The company has been involved with many large-scale projects in Australia, the U.K. and South Africa.
Great expectations There’s little doubt that large-scale projects and public-private partnerships (P3s) are exactly the kind of jobs that are most attractive to Canada’s leading contractors. “P3s are a big part of our growth market,” says Douglas. “And we took that same model to Australia and we were successful on our very first foray into that country.” Although more and more P3 projects are steadily coming online, we also asked our Top Contractors what other specific business areas they expect to see growth in this year and in 2013. The three key areas they cited are: oil and gas, design-build and mining construction. More than 77 per cent of respondents expect growth in the mining sector for 2012 and 83 per cent for 2013. Design-build project expectations come in at 68 per cent for 2012 growth and 74 per cent for 2013. Finally, 64 per cent of contractors expect an increase in oil and gas projects in 2012, and respectively 77 per cent in 2013 (for more details see Expectations chart on page 20). There are still challenges out there; but overall, contractors are in a much better place than they were just a few short years ago. It’s a luxury in this industry to face impending challenges, rather than having to react to excessive demand or economic crisis. Beck sums it up best: “It’s better to have a steady stream of growing business rather than these great big booms and then the bust we had in 2008. I like the idea of ‘steady as she goes’ development in Canada, and all the support systems that go with that—Steady Eddie over the long term.” Send comments to editor@on-sitemag.com.

The
Metro-Can-do attitude B.C. firm takes No.1 spot in 50 employees or less category
BY ANDREW SNOOK
Metro-Can Construction Ltd. Head office: Surrey, B.C. Number of employees: 50 2011 revenue: $100 million 2012 projected revenue: $125 million
T
his year’s Top Contractors report featured a 50 employees or less category, and Metro-Can Construction Ltd. took top spot with a reported 2011 revenue of $100 million. The Surrey, B.C.-based construction company has completed more than 280 projects since starting up in 1964. Metro-Can has worked in all segments of the construction market, including: multi-residential, commercial, light and heavy industrial, recreational and institutional projects; and is rated one of the top 50 general contractors in Canada and one of the top five based out of B.C. Don Voth, president of Metro-Can, says his company’s ability to figure out the clients’ needs and meet them in a timely fashion are what make the company so successful. Metro-Can has worked on numerous high-profile construction projects in B.C., such as the Olympic Village for the 2010
Olympic Winter Games, where they completed 13 high-end technically advanced buildings, 800 units and the civic centre on time under a compressed schedule. The project was awarded LEED Platinum and LEED Gold ratings. After the Olympics were completed, the site was transformed into the Millennium Water Residential Complex, which is made up of a combination of housing, retail and community space. Other high-profile projects include: the Oak Bay Beach Hotel, the City of Victoria’s first combination full-service luxury hotel and private residence with 100 rooms, including 20 luxury residences (completion date of September 2012); the Surrey, B.C.-based Ultra, a 40-storey, concrete high-rise with 362 units, including 11 two-storey detached wood framed townhouses (completion date of April 2013) and the Alexandria, a 20-storey high-rise building being built to LEED Gold standards in Vancouver, B.C. Voth says one of the company’s biggest ongoing challenges is pricing out projects up to one year ahead of time. “We’re always trying to out-guess where the commodities are going to be.”
Metro-Can Construction Ltd. has worked on a variety of highprofile projects throughout British Columbia, including the Olympic Village for the 2010 Winter Games in Vancouver, B.C.
50 employees or less
Top 5:
Metro-Can Construction Ltd. – $100 million (Surrey, B.C.) LCL Builds Corporation – $59.35 million (Toronto, Ont.) Bockstael Construction Ltd. – $51 million (Winnipeg, Man.) Rosati Group – $50.31 million (Windsor, Ont.) Reid & DeLeye Contractors Ltd. – $50 million (Courtland, Ont.)
One common challenge in the construction industry that Voth says hasn’t affected his company is a shortage of skilled workers. He says workers tend to stay with the company long-term. The fact that the company offers a variety of incentives, such as a retention bonus program, certainly doesn’t hurt. Metro-Can is also active in the community, offering support in Canada and abroad. Voth says the company has donated to various cancer research programs in Canada; and fund programs to build water wells and radio stations in several countries throughout Africa and Asia. “We have rigs with qualified people to drill the wells; we’re moving into our seventh year,” says Voth. “We think the water wells are a big deal. It is the social centre of a village.” Although the company mainly operates out of B.C., there are plans in place for expansion. Metro-Can recently opened an office in Toronto, Ont., and that’s just the beginning of its long-term goals. Voth says the company hopes to expand into every province one day. With a projected revenue growth of 25 per cent for 2013 and a variety of high-profile projects under its belt, Metro-Can appears to be building itself a bright future. www.metrocanconstruction.com

ROAD BUILDING
True grit BY JIM BARNES
F
or several years now, the Ministry of Transportation of Ontario (MTO) has had its sights set on perpetual pavement—highways that will last, if not eternally, at least for the foreseeable future. One of the keys to realizing this dream seemed to be using durable, stone mastic asphalt (SMA) as the surface course. That was, until issues with skid resistance emerged that put the process on hold. Lately, one Canadian roadbuilder seems to have solved the problem. The notion of “perpetual” pavements started to gain currency in Ontario in about 2003. “The intent is to build the pavement thick, with an elastic layer on the bottom. That way, there is enough material to flex when traffic runs on it. If it cracks, it only cracks at the surface, so it can be repaired easily,” explains Tom Dziedziejko, general manager, AME Materials Engineering, Toronto. “They were going pretty hard with SMA and perpetual paving,” adds Donn Bernal, general manager, Materials, Aecon Special Materials Ltd. “They knew it was an excellent product that had been proven in Europe. Everyone was excited about it. There were a lot of trials that showed its benefits.” He adds that even though SMA is a more expensive mix, there were significant advantages in terms of life-cycle costing. In 2006, the first full-service perpetual pavement highway using SMA as the surface-course mix in Ontario was built: the Red Hill Valley Parkway.

STONe SKeLeTON SMA has been used in Europe since the 1960s and has now been used in several projects in Ontario, on highways with vehicle loads of more than three million equivalent single axle loadings a year. The stone-on-stone “skeleton” structure formed by coarse aggregate in the mastic composition is the key to its durability. In addition, its high asphalt cement (AC) content improves binder durability. Bitumen drainage during transport and placement is controlled with cellulose or mineral fibres that are also used in this mix. Precise compaction is an important concern with SMA; the mix cools rather quickly, and drum rollers must be used
including changing the mixes, and published a paper on what we found. In the end, the only real way of doing it was to try gritting—rolling sand into the surface.”
ruBBer HiTS rOAD The rubber hit the road with Ontario tender 2007-2026, covering grading, drainage, granular base, hot mix paving, illumination, traffic signals, structures and an Advanced Traffic Management System on the Queen Elizabeth Way (QEW) from Burloak Dr. to Third Line. The total value was $88.7 million, according to the tender. “The section we were working on was to be widened significantly,” notes
Precise compaction is an important concern with SMA; the mix cools rather quickly, and drum rollers must be used.

Sand gritting is helping pave the way to perpetual pavement
to prevent working the binder material to the surface and ruts. However, of greater concern than compaction was skid resistance. Questions about SMA’s capabilities in this regard have been asked internationally. “The issue is that there was quite a bit of AC coating the aggregate,” says Bernal. That tended to reduce friction noticeably, compared to conventional asphalt. The effect only lasts for a couple of weeks or so after exposure to traffic. In the MTO’s eyes, though, that was bad enough. The use of SMA in Ontario was officially paused. A joint MTO/Industry Task Group on SMA mix design, construction and treatment was established to identify a solution. “As much as the industry might have liked to see ‘reduced speed’ signs go up for a couple of weeks, you have to hand it to the Ministry for their concern with public safety,” says Dziedziejko. “I was on the committee that was brought together to look at this issue. We tried a number of different approaches,
Dziedziejko. It was a four-year job, with the surfacing completed in 2011. “The SMA was bid into the job, so they couldn’t really tell us not to use it despite the official pause. But this offered the opportunity for the gritting trial, to demonstrate that it would work.” The MTO put out a non-standard special provision for safe construction with a specification for gritting of stone mastic asphalt, according to Bernal. This was going to be a pioneering project; it had never been tried before in Ontario, he adds. The first challenge was finding a suitable grit-spreading machine. Dynapac, which had experience with the application in Europe, brought in a special roller for the job. “In Europe, this kind of gritting is done pretty regularly. Their roads are a little different, and their surface course asphalts use normal aggregates that do not necessarily have a high skid resistance. They incorporate the grit to raise the skid resistance,” says Dziedziejko.

Grit application and MTO observers.
The machine was a fairly typical 55-in. roller with a bin on the front of it, according to Bernal. The bin contains a special grade of sand, which is spread out by rotating brushes at a controlled rate through an adjustable opening in the bottom.
GOiNG TO TriAL “The machine just kind of showed up here, and we had to figure out how it worked and how to configure it,” says Bernal. “The first thing was figuring out what the spread rate was… We did some trials at the plant with regular sand to see what speeds and settings we could use.” The operation itself was pretty conventional in concept, according to Dziedziejko. They would place the asphalt as normal, and right behind the paver came the grit spreader. “It spread sand on top of the SMA while it was still hot and rolled it in at the same time. It was part of the compaction process.” The first step was trials. “We went out on the North Service Rd. and did trial strips on some SMA there,” says Bernal. Some experimentation was necessary. “There were two different ways we did it,” says Dziedziejko. “We did it with an uncoated grit, which was just the dried sand.” The second was with a coated material, made by adding one per cent AC to the sand. After a little fine-tuning, “That’s what seemed to work the best.” Without the AC, the sand tended to cling to the roller. “You had a problem with buildup on the rollers and the odd imperfection on
the road.” Once the appropriate application of the AC was determined, “It didn’t stick to the rollers and it went down smoothly and uniformly. It went down very, very well,” says Dziedziejko. The first trials were conducted with one kilogram of sand per square metre of asphalt. “We had to demonstrate to MTO that we could get the one kilogram per square metre” says Dziedziejko. In the final work on the QEW, though, they tried two sections at 0.7kg/ m2 and 0.76 kg/m2. The grit itself took a little pre-treatment. “The Ministry asked us to recommend a few different grits, or sands,” says Dziedziejko. He wound up submitting four different products to them. “They wanted something that was reasonably clean and hard. They settled on a couple of choices. One was a clean, concrete-type sand from Caledon. The other was a manufactured sand from our Marmora quarry.” Ultimately, the material from Caledon was selected.
MiX reSuLTS The SMA mix itself was 79 per cent coarse aggregate, says Dziedziejko. It was designed with 5.4 per cent AC. He notes that 75 per cent of the material was retained on the quarter-inch sieve. The mix incorporated cellulose fibres at 0.3 per cent. The asphalt cement itself was a PG 70-28. The aggregates used were trap rock out of Aecon’s Marmora quarry. “It used the stone and a washblend sand, and then there was a filler from E.C. King. Maximum size on the material was 16 millimetres, so everything was smaller

than 5/8 of an inch and 95 per cent of it was smaller than a halfinch,” he says. “The mix had good properties all the way through,” he adds. It was mixed in a drum mix plant in Brampton and hauled from there. Skid testing obviously had to be a key part of the trials. “We had to determine the skid resistance, before and after, and document the improvement so they brought out a skid tester,” says Bernal. The gritting “did amazing things,” says Dziedziejko. “The initial numbers on the trial section were significantly higher than they were without it—way above the minimum.” “The MTO checked the skid resistance, and at our last committee meeting everyone was happy with the skid resistance,” says Dziedziejko. “They plan to recommend to the MTO that they lift the pause on SMA as long as gritting is part of the job.”

nothing. We were expecting to put down this one kilogram per square metre, and then have to haul three quarters of it away. We found that 75 or 80 per cent of the material actually got embedded and there was hardly any dust.” Another surprise was the appearance of the pavement after gritting. “The texture of the road after you are finished is not the nice, shiny black surface you’d expect,” says Dziedziejko. “The sand grit gives it what you would think of as a worn appearance, lighter in colour. It’s nice to have a smooth road to drive on—but you want to be able to stop!” The MTO was satisfied with the results and has allowed SMA back into the specifications with the added gritting specification, notes Bernal. This procedure will probably become the standard in Ontario. Bernal predicts that the grit spreader they used is just the first of many to be seen in the province. Dynapac already has plans to introduce a model with a 66-in. roller. Other manufacturers can be expected to jump on this bandwagon, too. The skid resistance committee is going to go back to the different regions and suggest that they give SMA another chance, with the addition of the gritting operation. “With some Rely on the Wirtgen Group’s full range of products for new construction and luck, we will have smoother, safer more durehabilitation of roads.

“One of the things that surprised us with the gritting operation was just how much of the grit actually wound up getting embedded,” says Dziedziejko. “We were expecting very dusty conditions.” Even though the uncoated grit was a little dustier, it still was not that significant, notes Dziedziejko. “The coated grit was almost

e’ve still got time. That seems to be the failsafe view of contractors facing a mandatory shift in Canada to interim Tier 4 emission standards in some new off highway equipment at the end of 2014 and to full Tier 4 standards by the end of 2018. Until then, some contractors have chosen to delay their purchases of Tier 4 engine equipment as long as they can; others continue paying fees for the right to produce higher levels of nitrous oxides and particulate matter using older engine technology. Manufacturers in the meantime, are trying to help contractors understand how they can meet Tier 4 standards without blowing a hole in their equipment budgets or negatively impacting their operations.

EPA-mandated interim Tier 4 regulations went into effect January 2011 across the 174 to 751 hp (130-560 kW) power category, requiring diesel engines to reduce particulate matter (PM) exhaust emissions by 90 per cent and NOx exhaust emissions by 45 per cent, compared with the Tier 3 and Stage IIIA emissions standards. Beginning in 2014, off-highway diesel engines in this power category must reduce NOx emissions by a further 80 per cent compared to 2011 levels. In 2014, NOx and PM exhaust emissions are expected to be reduced by 90 per cent compared with current Tier 3 and Stage IIIA levels. Some companies can delay their purchase of new Tier 4 equipment by taking advantage of transitional engine allowances. For

i.e., burned off at normal exhaust temperatures. To remove larger particulate build up, companies such as Cummins and Komatsu employ filters and hydrocarbon dosing technology that involves injecting small amounts of fuel into the exhaust stream to produce a chemical reaction that generates sufficient heat to burn off the soot. Exhaust Gas Recirculation (EGR) works by recycling a small amount of cooled exhaust gas back into the combustion chamber, cutting combustion temperatures and NOx emissions. EGR-equipped engines are very effective at reducing NOx and will not require SCR after-treatment to capture the remaining NOx and PM. Because it increases particulate emissions, however, it will likely be used in conjunction with DPF to meet both Tier 4 Interim and Tier 4 Final regulations. Both Cat and Cummins employ a cooled EGR system to remove NOx, in Cummins’ case reducing these gas emissions by 45 per cent compared to Tier 3. Currently, DPF and hydrocarbon dosing technology appears to be the technology of choice for many equipment manufacturers. Like EGR, the best part about DPF technology is that it kicks in automatically. “During regeneration a symbol pops up on the monitor panel that indicates it is occurring,” says Morris. “There’s no effect on performance.” But Tim Stewart is not so sure. In fact, the general manager for Imperial Paving in Burnaby, B.C. says his main reservations around Tier 4 technology for off-road equipment stems from his experience with similar technology in on-highway emission equipment. Last October in the middle of a job, on-board systems designed to identify and automatically clean out soot from

The computer is telling me it has to flush it out. It’s sitting there at high RPMs in the middle of a residential area.” Kisko is concerned about the effectiveness of dosing regeneration systems at cold temperatures. “I have yet to see any data that shows that at -40 that chemical reaction will still create enough heat for full and proper regeneration. It is obviously a concern.” Because Cat uses on-board incineration to create an actual burn, Kisko says it “has no problem” generating the heat needed to reduce soot under cold weather conditions.
The Cummins 15-litre QSX15 uses Exhaust Gas Recirculation (EGR) and a diesel particulate filter to meet Tier 4 interim emissions regulations
But on-board incineration devices pose a concern for engine designer and manufacturer Kubota in the added space the device takes up on an already well-loaded vehicle. “We have some large customers in the Kubota world like Carrier and Bobcat,” says Canadian sales and marketing manager J.P. Ouellette. “Where are they going to fit all that on their reefers and skid steer loaders?” Right now the DPF has the advantage in the marketplace, he adds, but Kubota is considering introducing SCR technology after improvements are made and in time for full Tier 4 implementation.
Less or more costly? You be the judge Ultra-low sulphur fuels and low-ash engine oils are important for overall engine wear and keeping Tier 4 regeneration systems working at optimal rates. So, too, is general maintenance, with particular attention paid to cleaning the DPF. Komatsu provides two filter exchanges within five years enabling contractors to meet the EPA’s mandatory 4,500-hour clean filter requirement and avoiding additional cleaning or purchase costs.

In addition to its filter exchange program, Cat offers a portable cleaning system and larger non-portable cleaning systems at Finning dealerships. Because the entire regeneration in DPF occurs internally it is especially helpful to compact equipment operators, says Bobcat’s Chris Knipfer. “As an operator or owner you don’t take anything off or change the filter for about 3,000 hours,” at which point Bobcat owners may choose to switch out machines completely and buy a new one. While Tier 4 technologies bring with them added complexity, most agree this will not place a large additional burden on company mechanics. Engine manufacturers and dealers provide ample guidance in maintaining the filters and other components, backed up by generous service support. What remains to be seen, however, is the increased cost of Tier 4 off highway equipment overall. Relying upon EPA evidence, Environment Canada estimates the price increase on imported Tier 4 heavy equipment will

be less than three per cent on average for most models. Knipfer doesn’t believe that. Assuming additional Tier 4 costs are passed on to customers, “everything I’ve heard in our industry is that the price increase will be anywhere from seven to 15 per cent,” he says. For his part, Krieger expects about a $4,000 increase in Genie’s telehandlers as they move from Tier 3 to Tier 4 Interim requirements, with an additional $2,000 as Tier 4 Final requirements become mandatory. Are there cost advantages to moving toward Tier 4 standards? Sure, says Knipfer. Tracking fuel consumption is much easier today, he says, because of Tier 4 influenced electronics. “We can track fuel consumption now whereas before it wasn’t something common in the industry. A lot of customers ask for that, especially if they have a fleet and are trying to budget for the next year.”

for keeping safe in the trenches BY ANDREW SNOOK
I
n April of 2012, a 53-year-old construction worker lost his life when he was buried alive in a tragic trenching accident in Lachine, Que., despite the best efforts of co-workers and emergency rescue staff. Working in trenches is a dangerous job. From potential cave-ins to falling objects, workers have to constantly watch for a variety of deadly hazards. Rick Preszcator, regional safety director for EllisDon in Toronto, Ont., has more than 27 years of experience in the construction industry and knows what needs to be done on the jobsite to ensure everyone gets home safe. “Pre-planning is the biggest thing,” he says. “If you are using the proper tools and the proper hazard assessments you should not have accidents.” Constantly assessing worksites is vital for keeping people safe in the trenches. Preszcator says daily pre-job safety assessments (PSAs) are a tool that helps workers stop, think and put controls in place.
“If you do something like a PSA daily, it’s a good way to prevent complacency.” The safety culture within the construction sector has changed dramatically over the past two decades. It has a higher presence now than it did 20 years ago, and most companies have full-time safety employees in place to keep workers out of harm’s way. Educating the workforce has become a top priority. “We do a lot of in-house training. You have to make everyone aware of potential hazards, the tools you’ll use and the procedures for doing it. Everyone knows what everyone else is doing. It’s careful planning and careful preparation,” explains Preszcator. He says the number of incidents and accidents 15 years ago— even 10 years ago—have gone way down, a comment echoed by Mike Chappell, provincial coordinator for the Construction Health and Safety Program (CHSP) at the Ontario Ministry of Labour. Trench collapses were a major problem from about 1982 to the

require constant support and containment (See Soil Type sidebar for details). Soil types can change quickly depending on a variety of factors. It’s vital to reassess the soil at a jobsite regularly, especially when weather has changed. Tip #5 – Be wary of vibrations, even from afar Vibrations caused by machines—even 500 feet away—can make a difference to the structural integrity of a trench. Ongoing operations like earth moving or compaction and vehicular traffic may seriously affect the integrity of trench walls.

In the past, people may have recognized that it would collapse, but they wouldn’t think it was going to collapse at that moment,” Chappell explains. “They all thought ‘Well if it did collapse we would all go down with a shovel and dig them out and carry on,’ so they took those risks, and most of the time they got away with them.” The combination of increased enforcement by the Ministry of Labour and its focus on trenching has caused more of the workers and employers in the trenching business to provide shoring protection. Tip #1 – Use the proper cave-in protection for the job There are three ways to provide proper trenching protection: sloping, shoring and trench boxes. Remember to check the Ministry’s safety guidelines and requirements before you dig. Do your research and find out what type of protection is best suited for the soil conditions on your jobsite. The most common type of protection used is sloping the walls of the trench—often used with shoring or trench boxes. The second is a shoring system—timber or hydraulic, for example—which is used to support the trench walls to prevent the movement of soil, underground utilities, roadways and foundations. The third type of protection is a trench box for protecting workers from cave-ins. Each trench box should be able to withstand the maximum lateral load expected at a given depth in a particular soil condition. There are also slide rail systems, a kind of hybrid of trench box and shoring protection. It’s a component shoring system, comprised of steel panels and posts that are similar to trench shields. Tip #2 – Inspect the system regularly No matter what protection system you choose, it needs to be inspected regularly. Hydraulic shoring should be checked for leaks in hoses and cylinders, bent bases, broken or cracked nipples, and any other possible damages or defects. Timber shoring should always be inspected pre-installation—to remove damaged or defective lumber—and afterwards for signs of crushing. Trench boxes should be checked for structural damage, cracks in welds and other defects. Tip #3 – Keep the trench accessible Whether sloping, shoring or trench boxes are used for protection, workers must be provided with ladders so they can enter and exit trenches safely. The ladders must be placed inside the protected area, securely tied off at the top and extend above the shoring or box by a minimum of one metre. Tip #4 – Watch the soil One of the most significant factors that endangers the lives of workers within trenches is the type of soil being excavated. There are four types of soil set out in construction regulations that range from Type 1, which is a hard soil to dig that tends to remain vertical and not release water when excavated, to Type 4 soils that can be excavated easily using a hydraulic backhoe but
Tip #6 – Never enter a trench alone If a trench is unsafe workers should not enter it, and never enter a trench, even a protected one, when alone. “The chance of being rescued is slim to begin with, but the chance of being rescued when alone is zero,” says Chappell. “The problem with soils, especially soils in the city, is that we don’t know when [a collapse] will occur. It could occur within seconds of being excavated, or it could occur several hours or several days later.” Tip #7 – Watch where you step Workers inside the trenches aren’t the only ones that experience trenching-related injuries. One of the most common ways people get hurt on-site is by falling over the edge of a trench or sliding down the edge of a bank. Tip #8 – Keep an eye out for falling debris In addition to cave-ins and falls, working in trenches comes with hazards such as piping, stones or debris rolling down an excavated bank and striking workers. Tip #9 – Remember to look up While a great deal of focus on the ground being dug up is necessary to ensure worker safety—locating underground utilities and setting up the necessary safety measures, for example—one of the biggest hazards that are sometimes overlooked is overhead powerlines. According to Infrastructure Health & Safety Association’s (IHSA)

TRENCHING SAFETY
Soil types Rick Preszcator, regional safety director for EllisDon in Toronto, overlooks a construction site in downtown Toronto.
The four soil types as defined by the Infrastructure Health & Safety Association’s (IHSA) publication, Trenching Safety: Introduction to Trenching Hazards: Type 1 — It is hard to drive a pick into Type 1 soil. Hence, it is often described as “hard ground to dig”. In fact, the material is so hard it is close to rock. If exposed to sunlight for several days, the walls of Type 1 soil will lose their shiny appearance but remain intact without cracking and crumbling. If exposed to rain or wet weather, Type 1 soil may break down along the edges of the excavation. Typical Type 1 soils include
publication, Trenching Safety: Introduction to Trenching Hazards, constructors must have written procedures in place to prevent equipment from intruding on minimum safe distances. For powerline voltage ratings of 750 to 150,000 volts, equipment must maintain a minimum distance of 3 metres (10 feet). For 150,000 to 250,000 volts, equipment must have a minimum safe distance of 4.5 metres (15 feet); and for powerlines with voltage ratings that are more than 250,000 volts, a minimum safe distance of 6 metres (20 feet) must be maintained. Tip #10 – Use extra protection whenever possible In addition to standard protection, such as hardhats, eye protection and Grade 1 safety boots, another protection measure workers can take is wearing a safety harness and attaching themselves to a lifeline. Depending on the soil condition within the trench, workers may also be required to wear rubber safety boots. Tip #11 – Have emergency plans in place Every company should have an emergency plan in place to deal with potential trenching accidents. “In the case of a cave-in you don’t have a lot of time,” says Preszcator. Rescuing a worker who has been trapped in a cave-in is a raceagainst time. The weight of the soil in a typical collapse is several thousand pounds, and it only takes 40 pounds of pressure on the average human chest on a sustained level to prevent them from breathing. “Essentially, if you’re buried in a trench collapse, the weight of the soil pushes the air out of your lungs and then it’s a ticking clock, and a very short ticking clock, before the worker is killed… my experience with trenching is that it’s seldom that you see a positive outcome when a worker is buried,” says Chappell. Tip #12 – Make sure everyone receives training There is a wide variety of trench safety training programs offered through public and private companies, and many unions do their own training as well. The Ministry of Labour offers videos and literature on trench safety on its website free of charge for the public. Preszcator says if you plan your work and work your plan, then all of your safety measures should be in place. “The bottom line is you have to make it a safe work environment. Everybody goes home at the end of the day.”
“hardpan,” consolidated clay, and some glacial tills. Type 2 — A pick can be driven into Type 2 soil relatively easily. It can easily be excavated by a backhoe or hand-excavated with some difficulty. In Type 2 soil, the sides of a trench will remain vertical for a short period of time (perhaps several hours) with no apparent tension cracks. However, if the walls are left exposed to air and sunlight, tension cracks will appear as the soil starts to dry. The soil will begin cracking and splaying into the trench. Typical Type 2 soils are silty clay and less dense tills. Type 3 — Much of the Type 3 soil encountered in construction is previously excavated material. Type 3 soil can be excavated without difficulty using a hydraulic backhoe. When dry, Type 3 soil will flow through fingers and form a conical pile on the ground. Dry Type 3 soil will not stand vertically and the sides of the excavation will cave into a natural slope of about 1 to 1 depending on moisture. Wet Type 3 soil will yield water when vibrated by hand. When wet, this soil will stand vertically for a short period. It dries quickly, however, with the vibration during excavation causing chunks or solid slabs to slide into the trench. All backfilled or previously disturbed material should be treated as Type 3. Other typical Type 3 soils include: sand, granular materials, and silty or wet clays. Type 4 — Type 4 soil can be excavated with no difficulty using a hydraulic backhoe. The material will flow very easily and must be supported and contained to excavate to any significant depth. With its high moisture content, Type 4 soil is very sensitive to vibration and other disturbances, which causes the material to flow. Typical Type 4 material includes muskeg or other organic deposits with high moisture content, quicksand, silty clays with high moisture content, and leta clays. Leta clays are very sensitive to disturbance of any kind.

Additional factors include: the corrosive nature of the ambient ground water, which led to minimizing the use of steel reinforcement in the final liner; and the need to make the tunnel as hydraulically efficient as possible to reduce head losses due to friction, which would directly affect the additional electricity generation at OPG’s Sir Adam Beck hydro stations. The concrete liner will require approximately 300,000 cubic metres of concrete in total and is poured in two stages: first, the invert (the bottom one-third of the liner) and later the arch (the bigger of the two pours that completes the top two-thirds of the liner). Using two separate form carriers, Moorhouse says the workers can complete 25‑metre long sections of invert concrete and arch concrete each day. He says the invert concrete is more than 90 per cent complete, while the arch concrete is over 60 per cent complete. The majority of the concrete for the project is supplied by two sources: an on-site, dedicated batch plant, supplied by Dufferin Concrete, and a second Dufferin plant located in

Niagara Falls, Ont. Bernhard Mitis, construction manager for Strabag at the Niagara Tunnel Project, says the biggest challenges his team has faced thus far are logistically related, due to the number of trucks running in-and-out of the tunnel; including those transporting the concrete to where it needs to be. “At this point right now we have the invert concrete [liner], the tunnel arch [concrete liner] and two grouting and restoration operations.” For the first 1.4 kilometres of the arch lining, concrete was pumped directly to the forms from the outlet portal. “That was the limit of how far we could pump it and maintain quality,” says Moorhouse. Since then, concrete has either been delivered by largecapacity mixer trucks through the tunnel, or gravity-fed through one of four steel drop shafts spaced along the length

SOFTWARE By Jacob Stoller
N
Five software procurement tips and tricks
o construction company would invest in a piece of heavy equipment without taking a careful look at its intended workload. When it comes to buying software to run the business, however, many forge ahead with little more than a rough idea of what the technology will actually do. While business applications have played a major role in running construction firms for at least a generation, the details of how they operate are, unlike many aspects of the construction trade, not visually apparent. Consequently, many firms who meticulously maintain their construction equipment rely on decrepit, outdated IT systems for their most critical business functions. George Goodall, who has a background in construction and is currently a senior analyst with London, Ont.-based Info-Tech Research, recalls an example. “The firm had lots of sites in a rural area, with no internet access, and they wanted to implement a program with time cards,” says Goodall. “So they hired a person to sit in a truck all day and collect the cards from the workers, and then drive to a Tim Horton’s where there was Wi-Fi.” The costs of workarounds are not usually this obvious. If it takes an accounting clerk five days to close off a month, few people may be aware that with the right IT systems in place, this should only take two days. Software can be a powerful business tool, but if it’s not properly matched to its workload, it leads to high costs, disruption, employee dissatisfaction, errors, or noncompliance with government regulations. Investing in business software requires the
same methodical approach you would use for any major piece of equipment. Here are five tips for getting it right the first time: 1. Define your objectives Software projects take on a life of their own unless objectives are clearly defined. Tighter control of financials, better management of assets, or improved project management are all legitimate goals, but they must be agreed upon at the outset. Wish lists tend to grow when people learn that there is a software project in the offing, and the scope can become unmanageably large. Goodall recommends three key objectives for any single project. 2. How is the work currently being done Business software plays a fundamental role in how people do their jobs, so it’s very important to understand how affected employees are currently doing their work. If a person does estimating, what are the steps of the process? Getting answers may seem tedious, but it is far worse if down the road, the employee is stuck with software that is poorly matched for the job. 3. Decide how a job will be done An impending business software implementation puts a number of options on the table. Goodall divides these into three categories: apply the software to the existing process; adopt a new process based on the software capabilities; and adopt an “ideal” process based on recommendations from users or consultants. Each has advantages and drawbacks. The existing process could be inefficient and outdated. A process based on readily available software capabilities may require users to jump through hoops. This could also entail high training and change management costs,

and possible resistance from employees. Adopting a specially-designed process might involve customization and high support costs. 4. Create a spec. The document doesn’t have to be a formal tender, though, and vendors generally provide better responses to brief, straightforward RFPs. One approach that works well is to openly state your business objectives, and give the vendor the opportunity to come up with a creative solution. The advantage here is that you can then hold them accountable on your terms. 5. Look at the big picture If all the software brochures look alike, it’s in part because construction software has matured, and products, at least from a features and functions perspective, may be very similar. It’s essential, therefore, to look closely at lifecycle considerations such as installation, user training, ongoing support and upgrade paths. 6. Make the commitment Software that supports major business functions such as estimating, project management, or accounting has a profound impact on how these tasks are carried out. A mismatch can lead to huge costs down the road, or even worse, significant business risks. While many business people prefer to keep IT issues out of sight and out of mind, investing the time to get it right is really a matter of “pay me now or pay me later.”

RISK By David Bowcott
R
Balance your capital to maximize opportunity
eturn on investment. One of the most difficult questions faced by the board of directors and management of any corporation is what the right balance is between capital retained and risks assumed. We’ve all heard the comments—“this company is overcapitalized,” “this company is stretched to its limits,” “this company’s capital base is in line with its backlog.” These are perceptions of investors, creditors, competitors, employees, management, directors, analysts, etc. At the end of the day they are perceptions largely based on historical business norms. In today’s construction marketplace, what is an adequate capital balance based on the risks taken on by a construction company? This question becomes much more intriguing when you consider all of the options that construction contractors have available when they are fortunate enough to be faced with excess capital. They could dividend the capital to shareholders, acquire a construction company, buy back their shares, invest equity in projects, acquire a facilities management contractor, or leave the capital within the company to absorb unforeseen events. The temptation to do something more active with your capital is growing. So what’s the right level of capital based on the risks at your company? That’s a question that several of your business partners will most definitely have an opinion on. Without a doubt there isn’t one answer. Several factors need to be considered to determine whether the capitalization of your company is adequate, too low or too high. Some of these factors include:
The nature of your backlog – What type of risk is your company exposed to through contracts? There are several contract models used in today’s marketplace and they all have varying levels of risk. Through construction management agency obligations you may be taking on very little risk. Through design-build fixed-price contracts you may be taking on significant risk. In some cases, a fixed-price contract could be less risky than a construction management contract simply because of the risks you control. For instance, a well-planned fixed-price contract where the contractor procures the design, ensuring buildability, could present far less risk than a construction management at risk obligation whereby design control is in the owner’s hands. Detail on the nature of risk in the contracts taken on by your company is absolutely vital in determining adequate capital levels. In addition to your upstream contracts to owners, be aware of how you transfer risk via your downstream contracts to subcontractors, sub-consultants and suppliers. Your risk controls or best practices – Often overlooked, the operational practices your company has in place to manage risk are crucial in determining capital adequacy levels. These are practices that include design procurement practices, project go or no go assessment, subcontractor prequalification practices, subcontractor award practices, subcontractor management practices, etc. Having these risk controls in place is important, but actually executing these practices in the field will help determine how much capital is needed on your balance sheet to absorb unexpected risks. The nature of the risk transfer solutions – To protect your capital from risks taken on
through contract, you purchase insurance and you have subcontractor and supplier performance security. These risk transfer solutions can cover everything from faulty design risk, to property damage, to faulty materials delivered to your project, to your company being sued for causing damage to a third party. What these forms of “balance sheet insulation” cover and how they interact and respond is a crucial aspect of determining how exposed your company is to the risks it has taken on. The level of your company’s unsecured and secured corporate guarantees – Your company has several guarantees that constrain your balance sheet to varying levels. These could be guarantees to owners to secure project performance, guarantees to banks to secure lines of credit or a letter of credit facility, and guarantees to surety companies to secure your surety facility. These guarantees allow your company to operate and win business. The severity of these guarantees relative to what you are getting could constrain your balance sheet more than necessary; requiring higher levels of capitalization than your company may need. Do everything you can to minimize the constraints these guarantees impose on your balance sheet. The greater the clarity you have on these items within your company, the easier it will be to arrive at the ideal capitalization level. Arriving at that optimum capitalization level should ensure your ROI is best in class. David Bowcott is senior vice-president, national director of large/strategic accounts, AON Reed Stenhouse Inc.

CONTRACTORS & THE LAW By Chris Eagles & Brad Woods
Who’s design is it anyway?
A
common feature of most construction contracts is the inclusion of a detailed specification, prepared by the owner or the owner’s consultant, describing the requirements for the work to be performed by the contractor. Where performance problems arise in connection with the completed work, there are often disputes with respect to responsibility for the performance failure. Is the owner, as author of the specification, responsible for the non-performance? Or is the contractor responsible for the failure to discover and rectify the source of the non-performance? The answer depends on the terms of the parties’ agreement. When reviewing the terms of a proposed construction contract, it is important to consider and understand the allocation of design risk and responsibility. When determining the allocation of risk and responsibility for the accuracy of the specifications and for the ultimate performance of the work, it is important to consider the express terms of the agreement as well as the underlying nature and structure of the agreement; including factors such as whether or not the owner is relying on the skill and judgment of the contractor with respect to the suitability of the design. As a general rule, where a contract is silent with respect to the allocation of risk and responsibility for the performance of completed work, the owner will retain responsibility for the adequacy of the specifications; while the contractor will be responsible for ensuring that the contracted work complies with the specifications. Where the specifications will not permit the
desired performance to be achieved, the owner, as the author of the specifications, retains responsibility for the failure. In a Supreme Court of Canada case, the court was required to determine responsibility for the installation of brick that was found to be unsuitable. In that case, the court concluded that the contractor was not responsible for the performance failure because the owner had specified the
It is important to consider and understand the allocation of design risk and responsibility.
kind and quality of brick to be used. There was no indication that the skill and knowledge of the contractor was relied upon and the contractor had ultimately performed the work in accordance with the owner’s specifications. Despite this general rule, it is important to consider whether there are any contractual provisions that have the effect of transferring some or all of the design or performance risk to the contractor. In another case, in which a dispute arose with respect to responsibility for the cost of correcting damage caused by the failure of a product specified by the owner, the Supreme Court of Canada concluded that the contractor was liable for the cost of correcting the damage because the contractor had guaranteed that “all work above specified will remain weather tight and that
all material and workmanship employed are first class and without defect.” Other common contractual provisions that may transfer some or all of the risk and responsibility for design include: obligations to review and advise of deficiencies in the contract documents; temporary work provisions; and provisions relating to preparation of shop drawings. Contract Document Review: Pursuant to CCDC—2 (2008), the contractor is obligated to review the contract documents and report errors, inconsistencies and omissions, but without assuming any responsibility for the accuracy of such review. Temporary Work: Pursuant to CCDC – 2 (2008), the contractor is responsible for the design, erection, operation, maintenance and removal of temporary work, unless the design of such temporary work is specified in the contract documents. Shop Drawings: Shop drawing provisions often make the contractor responsible for the design of the specific elements of the work depicted in the shop drawings, even though the contractor may not be responsible for the overall design of the project. When entering into a construction contract, it is vital to carefully review the terms of the agreement to ensure they align with the parties’ understandings regarding the allocation of risk and responsibility, including design and performance risk. The allocation of design risk will generally reside with the party that is responsible for the applicable design; however, both the nature of the agreement and the specific contractual terms of the agreement can transfer design risk, and the obligations that go with it, from one party to the other.
