12 reasons to love the federal budget

Get the latest construction news!

Follow us on Twitter @OnSiteMag

ontractors across the country were ‘highfiving’ each other after Finance Minister Bill Morneau tabled the federal budget on March 22. And rightly so!

The government’s long-term commitment to infrastructure and labour initiatives will not only address Canada’s need for key infrastructure investments, but will also make a significant impact in stimulating our economy.

Not surprisingly, the federal budget is getting a ‘thumbs up’ from construction leaders across the sector.

“Budget 2016 commits an impressive additional $60 billion plus in new federal infrastructure investments in two phases, while accelerating portions of the existing Building Canada Fund,” said Michael Atkinson, president of the Canadian Construction Association.

“The federal government clearly recognizes that there is an urgent need in Canada to make key infrastructure investments across the country,” said PCA president Paul de Jong.

And appreciation from industry experts continues to roll in. (For more, see Construction leaders applaud federal budget initiatives on page 8) Budget 2016 is a pretty hefty document to wade through. In an effort to make life a little easier, here’s 12 reasons that contractors should love the federal budget: 1. $60 billion plus in new federal infrastructure investments in two phases, while accelerating portions of the existing Building Canada Fund.

2. Commits unused portions of the previous Building Canada Fund to the Gas Tax Fund over the next two years.

3. $3.4 billion in investments for federal infrastructure assets.

4.

$2 billion over three years starting this fiscal year for a new post-secondary institution investment fund.

5. $3.4 billion over three years to upgrade and improve public transit systems across Canada.

6. $5 billion over five years for investments in water, wastewater and green infrastructure projects across Canada.

7. $3.4 billion over five years for social infrastructure spending on social housing, early learning and child care, cultural and recreational infrastructure, and community care facilities.

8. $125 million in 2016-17 for Labour Market Development Agreements (LMDA) and an additional $50 million in 2016-17 for Canada Job Fund Agreements.

9. $2.24 billion over five years to improve on reserve water and wastewater infrastructure and waste management.

10. $255 million over two years to the First Nations Infrastructure Fund to support investments such as roads, bridges, energy systems and physical infrastructure to mitigate the effects of natural disasters.

11. Expanding access to EI for new entrants, reducing wait times for receiving EI, simplifying job search requirements, and extending EI regular benefits in certain areas.

12. Proposed $85.4 million over five years that is designated to support union-based apprenticeship training.

NATE HENDLEY / Freelance writer, editor & author On Certificate of Recognition: “COR certification is rapidly becoming a prerequisite for commercial contractors bidding on large projects, particularly in the Toronto area. Industry experts say COR certification could eventually become mandatory for all commercial construction jobs nationwide.”

ALEXANDER BJORNSON / Associate, Borden Ladner Gervais L.L.P On L&M bonds: “Labour and material payment bonds protect unpaid subcontractors where the contractor that hired them becomes insolvent or otherwise fails to make payment.

The protection provided by such bonds can vanish, however, when claimants do not know about them.”

ROSS MONSOUR / Director of marketing, Canadian Ready-Mixed Concrete Association On insuring wood structures: “The push for increased use of wood for high-rise buildings has raised several issues beyond constructability. The wood lobby has a high profile within government organizations, including the provision of subsidies. Consequently, it has also achieved a highly successful and visible campaign to increase the share of wood in high-rise buildings.”

INDUSTRY NEWS EllisDon’s Gilbert Brulotte elected 2016 CCA Chair The Canadian Construction Association (CCA) has appointed Gilbert Brulotte as chair of the 2016 Board of Directors.

“No matter how much new technology becomes available, if we do not have the right people in place to help optimize its use, the benefits will be lost or never fully realized,” said Brulotte, during his address to the association’s annual general meeting recently.

Ongoing education, training and setting aside time to mentor those individuals with leadership potential are some of the ways to ensure a thriving construction sector.

Brulotte is senior vice-president, civil division, EllisDon Corp. EllisDon is one of Canada’s leading employee-owned construction companies with operations across Canada and internationally, offering cradleto-grave solutions to its clients.

Brulotte’s 44 years in the construc-

tion industry include working for the public sector, family-owned firms, multi-national public companies, and being a shareholder of a local firm.

The scope of Brulotte’s work has ranged from municipal infrastructure in underground utilities and surface work to aggregate and asphalt production, trenchless

technologies and utility rehabilitation, as well as industrial construction in the oil and gas sector.

He has worked in every province from British Columbia to Quebec, in the Northwest Territories, and Central America. His passion is challenging the status quo and finding opportunities.

Brulotte joined the CCA board in 2005 and the executive in 2011. He served many years as a board member of the Alberta Roadbuilders and Heavy Construction Association with two terms as chair. He has also volunteered on technical committees for the City of Edmonton and Urban Development Institute-Edmonton Region.

Brulotte takes over the position from Anibal Valente, vice-president of PCL Constructors Inc., a group of independent construction companies operating in the civil infrastructure, heavy industrial, and buildings markets across Canada, the United States, the Caribbean, and Australia.

BIM agencies join forces Two groups driving the use of building information modeling in Canada have joined forces to further the interests of the national BIM community.

CanBIM and IBC/buildingSMART Canada are bringing together two of their key committees to work hand-in-hand. Their respective Owners and Education Committees will combine efforts to address the most pressing issues facing the design community in Canada. This will result in a clear set of outcomes that both agencies can support and endorse in a variety of ways, according to a joint media statement for the two agencies. Further, CanBIM, IBC/buildingSMART Canada are exploring opportunities for joint presentations and content, such as the CanBIM Regional Session in Halifax in June of this year.

“This is a significant step towards unifying all the BIM agencies in Canada, that at their heart, really have the same goals and aspirations,” says Allan Partridge, CanBIM president. “This is a significant step towards unifying all the BIM agencies in Canada, that at their heart, really have the same goals and aspirations.

“We will also see a streamlining of the valuable volunteer effort that has demonstrated a remarkable commitment to the committee work at both CanBIM and buildingSMART Canada with much better outcomes.”

Bob Hildenbrandt, chair of IBC adds: “The essence of BIM is a collaborative process that draws together the dedicated work of those involved. How better to demonstrate that collaboration to our industry

than to move forward in joining our efforts.”

John Hale, chair of buildingSMART Canada Operations Committee adds “We are thrilled to be working collaboratively with CanBIM and IBC; this will undoubtedly lead to a strengthened network of excellence for BIM in Canada.”

CanBIM and IBC/buildingSMART Canada believe this will strengthen and create a more robust BIM community in Canada. Both agree that a strong, resilient and highly collaborative community in Canada is needed to improve the design, procurement, assembly and operations of the built environment. At the same time we will unitedly create a stronger voice within the international BIM community.

INDUSTRY NEWS Infrastructure funding given to 5 Nunavut projects Five infrastructure projects have received joint federal funding under Canada’s Small Communities Fund.

The projects involve key community infrastructure in the territory, including a new cultural centre in Cape Dorset, repairs for the Cambridge Bay Arena and the Iqaluit Aquatic Centre. They also include an array of civic arena repairs and upgrades, as well as the replacement of outdated equipment at various playgrounds in the region. Once completed, these projects will contribute to stronger, more inclusive and sustainable communities in the North.

Through the Small Communities Fund, the governments of Canada and Nunavut are working in partnership to provide funding for priority public infrastructure projects that deliver on local needs in communities across the territory.

The Government of Canada will provide up to $25.36 million of the total eligible cost

of $49.9 million for these five projects. The Government of Nunavut will also contribute $6.54 million. Both the Hamlet of Cape Dorset and City of Iqaluit are contributing an approximate total of $18.1 million towards their own infrastructure projects. The Small Communities Fund allocation for Nunavut is $25.6 million.

New National Energy Code for buildings New buildings in Canada will become more energy efficient with the introduction of some 90 changes to the National Energy Code of Canada for Buildings 2015.

“As Canada’s go-to research and technology organization, the National Research Council is providing Canadians with solutions based on sound scientific knowledge and industrial innovation,” says Richard Tremblay, general manager of construction at the National Research Council of Canada.

“The construction industry is asking for more energy efficient design and building

solutions, and this new code will help them get there.”These changes also harmonize the code with Canada’s energy efficiency regulations and industry standards.

Updates can be found in standards for lighting, service water, and HVAC systems, such as gas-fired units on rooftops, and for ventilation systems in enclosed spaces like parking garages or warehouses.

The code builds on Canada’s commitment to work closely with the provinces and territories on the Canadian Energy Strategy, which protects Canada’s energy security and encourages energy conservation. Provinces and territories are free to adopt the National Energy Code of Canada for Buildings or adapt it to create a code that meets their specific needs.

The National Energy Code of Canada for Buildings 2015 is published by the National Research Council and developed by the Canadian Commission of Building and Fire Codes in collaboration with Natural Resources Canada.

Quick Facts •

•

•

New buildings constructed to the updated code will be 27 per cent more energy efficient than those constructed in 1997.

Energy efficiency in Canada’s commercial and institutional sector increased by 33 per cent between 1990 and 2012. The energy savings accumulated could power 45.5 million computers for one year.

The National Model Construction Codes, now called Codes Canada, are published approximately every five years to ensure that the latest innovations are applied safely by the construction industry.

INDUSTRY NEWS UBC builds 18-storey wood construction student residence The tallest timber tower in the world is under construction at the University of British Columbia.

The 18-storey Brock Commons Student Residence will be 53 metres tall when it is completed in 2017. The $51-million building is located on the Point Grey Campus in Vancouver, and will have more than 400 student rooms.

Because the building is significantly higher than the six-storey wood structures currently permitted by the provincial building codes, the project required Site Specific Regulation from the B.C. Building Safety & Standards Branch. Multiple layers of gypsum board encapsulate the mass wood structure for fire-rating purposes, but the wood is left exposed in an amenity space on the top floor.

It has an automatic sprinkler system with back-up water supply, and the compartmentalized units have a 2-hour fire rating between

Located on Walter Gage Road, near the North Parkade, the tower is a hybrid structure consisting of 17 storeys of mass timber construction erected on a concrete podium and concrete stair cores. The vertical loads are carried by the timber structure, and the two concrete cores provide lateral stability. Glulam columns with steel connectors support 5-ply cross laminated timber (CLT)

PCL’s Edmonton Buildings group worked with subcontractor Agra Foundations to install piles at the substation site. Cold winter weather meant that the traditional method of installing a prefabricated hoarding box over each pile cap, with an indirect heater attached to the box, was less than practical. Instead, PCL used pop-up ice-fishing tents with propane heaters. Overall cost savings using the tent plan as opposed to traditional heating and hoarding was $166,180.

ENVIRONMENTAL ACHIEVEMENT: MAPLE REINDERS GROUP OF COMPANIES FOR THE SECHELT WATER RESOURCE CENTRE PROJECT Maple Reinders took home the 2015 CCA Environmental Achievement Award for demonstrating how changes in design philosophy and an innovative process design can result in an asset that raises the bar for environmental standards.

Compared with the two existing plants, the new Sechelt Water Resource Centre (WRC) in Sechelt, B.C., uses nearly half the energy and has the capacity to treat twice the volume.

INTERNATIONAL BUSINESS: ELLISDON & PCL EllisDon and PCL were recognized with the 2015 CCA International Business Award.

EllisDon has acquired 40 years of success in international projects, and spent the better part of 10 years in the Gulf Cooperation Council (GCC) region, having successfully delivered work for the United Arab Emirates, the Kingdom of Saudi Arabia, Kuwait, Qatar and Afghanistan.

PCL’s practice of selecting and entering promising global markets, combined with a policy of allowing different divisions to flourish based on areas of strength in the larger economy, are at the base of its approach to global growth.

“These award recipients make me very proud of our industry and our contribution to the Canadian society,” said Anibal Valente, CCA’s chair.

“It is delightful to hear about the innovative approaches and what some of the truly exceptional companies, individuals and associations do.”

TRADE CONTRACTOR: STEPHEN COOTE, GROUP 92 MECHANICAL INC.

GOLD SEAL ASSOCIATION: CONSTRUCTION ASSOCIATION OF NOVA SCOTIA

CCA presented Stephen Coote with the 2015 CCA Trade Contractors Award for his enthusiasm and dedication to the trade contractors sector and to the construction industry as a whole.

A past president of the Niagara Construction Association, Stephen joined the CCA board in 2013 and is actively involved in the CCA Trade Contractors Council, the CCA Innovation and Technology Committee as well as the CCA Business and Market Development Committee. Borne of his involvement with the CCA, in 2013 Stephen adopted a key role in the start-up and operation of Canadian Construction Innovations (CCI) where he serves as secretary/treasurer.

The Construction Association of Nova Scotia (CANS) took home the 2015 CCA Gold Seal Association Award for its success in integrating Gold Seal into all aspects of its education program, and its work in promoting Gold Seal to its members and the industry.

NATIONAL SAFETY: GRAHAM GROUP The 2015 CCA National Safety Award went to the Graham Group for its commitment to safety at all levels and for its established track-record of continuous improvement.

In 2015 Graham’s Health, Safety & Environment Management System team focused on several key initiatives, including improving overall HSE performance, which resulted in a 90-per-cent reduction in loss-time incident frequency and severity.

PARTNER ASSOCIATION: VANCOUVER ISLAND CONSTRUCTION ASSOCIATION The Vancouver Island Construction Association (VICA) was recognized with the 2015 CCA Partner Association Award for its efforts in responding to members’ input and creating much-valued programs and services.

VICA’s efforts in government relations reflect its interest in fair, open and transparent practices in procurement. When its provincial government determined that bundling would be its preferred procurement method for building new schools, VICA took steps to address this issue that would have hindered its member firms’ ability to compete. As a result, the provincial government reversed its decision and will now consider bundling on a case-by-case basis.

COMMUNITY LEADER: PATRICK WAUNCH, RAMBOW MECHANICAL LTD. Patrick Waunch was presented with the 2015 CCA Community Leader Award for his support to the construction industry, and his local community.

Patrick was instrumental in growing Southern Interior Construction Association’s Secondary School Apprenticeship program and, in his role on the Okanagan College Mechanical Building Trades Program Advisory Committee, has not only helped build a strong program, but provided equipment to train with as well. The Patrick Waunch Scholarship Award assists mechanical trade apprentices.

Institutional construction intentions were down 20.2 per cent to $573 million in January, the third consecutive monthly decline.

Lower construction intentions for educational institutions, nursing homes and other government buildings accounted for the majority of the decline. Industrial construction intentions were up 30.6 per cent to $521 million in January, following a decline of 12.9 per cent in December.

Employment was virtually unchanged in February (-2,300 or 0.0 per cent) as gains in part-time work were offset by losses in full time. The unemployment rate rose by 0.1 percentage points for the third consecutive month, reaching 7.3 per cent for the first time since March 2013. There were 34,000 more people working in construction in February. On a year-over-year basis, however, employment in the industry was virtually unchanged. %

hile he is not being watched as closely as pitcher Marcus Stroman, contractor Vito Nardi definitely feels like he is squarely in the public spotlight. The job he is working on – preparing Toronto’s Rogers

Centre stadium, home of the Blue Jays for an all-dirt infield – is winning him a lot of attention. The project is drawing interest from local media and the sports world. “You’re on-camera constantly, so you make sure that everything goes smoothly,” says Nardi, president, Alliance Restoration Ltd.

Y DIRT As well as the unusual level of public attention, the project is on a tight schedule and represents a rather unique installation for any contractor. Previously, the base paths were concrete, covered with Astroturf and with dirt surrounding only the bases themselves. The existing concrete on the base paths is being removed to install a specialized mix of layers of gravel, sand and clay. The work must be completed by opening day in early April, despite use of the space during the construction period by two other major events.

COVER STORY

BATTER UP “We have been talking about [this project] for a long time. It was just a question of getting started with it,” says Kelly Keyes, vice-president, Building Services, Rogers Centre. The planning commenced in earnest when the Toronto Argonauts football team announced that it was moving to another stadium earlier than expected. Not having to support football at the stadium freed Blue Jays management up to install the new infield. “Management already knew what they wanted. It was just a matter of putting the plan into place,” says Keyes.

Alliance Restoration has an eight-year history at Rogers Centre. “There’s a certain trust level,” says Nardi. Among other projects, “We did all the expansion joints in the stadium itself and the waterproofing of the roof [not the dome, but the adjacent concrete roof].

The company can handle pretty well any kind of concrete work, including structural concrete restoration and waterproofing. For example, it has worked on parking garages on some very large commercial projects.

“Most of the work we do is in-house. We rarely sub work out,” says Nardi.

The firm is one of 10 divisions in

GETTING THE DIRT

The dirt infield is a far more sophisticated system than the dirt in your neighbourhood sand lot.

Previously, they had a four-inch depth of clay in the pit. That isn’t adequate for the new infield, though, since in summer months the clay tends to dry out quickly.

Tropicana Stadium, home to the Tampa Bay Rays, is the only other majorleague stadium to mix AstroTurf with a dirt infield. In the past, Tampa Bay has dealt with dryness and compaction issues. The Blue Jays have learned from this experience.

“We are the only two who do this,” says Keyes. “They use a different product, due to their climate… We’ve gone with the DuraEdge product.”

DuraEdge Products, Inc. of Grove City, Pa. designs and produces specialized engineered soil products for the athletic field industry.

“We will build this up to six inches. Then, we will put a temporary layer in so we can host [the other two events],” says Keyes.

“Moisture is an issue. We don’t want the soil to be too hard or too soft.

This product retains the moisture in the heat,” says Keyes.

“Every climate will be different. Outdoor stadiums in northern climates will be cold, and then really humid and hot in the summer. We have the ability to control the environment inside the stadium, which helps us to control the moisture,” notes Keyes.

the Verdi Alliance Group of Companies (Bolton Ont.), so it can get quick access to other construction specialties it may need as required. For example, Alliance Site Construction Ltd. is building the wooden forms for the concrete.

Nardi was conscious of the demanding deadlines and having immediate access to other services in-house was a big plus. “It’s not like you are depending on a third party to keep you on schedule,” he says. “That’s the bonus of being able to do things on your own – having the resources on staff and being able to say, ‘I need you guys there in a couple of days.’”

WORKING THE BASES The project involved measuring the field and cutting and removing some of the 26-year-old concrete to permit the installation of a specialized dirt mixture in the infield.

The job was laid out with a total station using AutoCAD files, with home plate and the foul lines serving as references, according to Nardi.

“All work has to be completed by the Blue Jays’ home opener in the first week of April against the Boston Red Sox.” Under-surface utilities were not a big issue for the contractor. “From our drawings, we knew where all the utilities were,” says Nardi. “We have not had anything unexpected happen… We did hit some electrical conduit and some water pipes, but those were all abandoned.”

They over-cut the infield area where the dirt is going to go. The next step was removing the broken slabs. Alliance Restoration

rented a 20-T excavator for the project, since it’s an unusual machine for this contractor to use. Their routine work is on structural slabs, not grade.

The wooden formwork is pretty straightforward, with straight lines except for the arc between first and third bases. They will then fill the area in with 16 to 18 in. of concrete, says Keyes. She adds that the new concrete will be an improvement. “Concrete technology has changed so much. We will make it harder.”

“The concrete is a slab-on-grade mix. It’s your typical 32C2 concrete, reinforced with rebar dowels on the edge to tie-in the slab with the apron we’re pouring,” says Nardi.

Once the concrete is ready, the infield area will be filled with a multilayer system consisting of two inches of gravel, four inches of sand and then the clay product, layered in two inches at a time with a laser grader.

The Astroturf will be laid to fit before the clay goes in.

Two major events have to be accommodated at the venue before the infield project can be completed: the Monster Energy AMA

“This job ran even smoother than I thought,” he adds. “They [Blue Jays management] were a little bit nervous about this job because it has to look good.

I think they’re extremely happy right now.”

“Alliance Restoration has been very, very easy to work with. They’ve helped to problem-solve,” says Keyes.

“I think that aesthetically, this will look a lot better than a sea of green.

And it’s a little bit better for the players, in terms of running and sliding,” adds Nardi.

HARD-COR SAFETY Will you be ready if COR becomes mandatory?

NATE HENDLEY

C

OR certification is rapidly becoming a prerequisite for commercial contractors bidding on large projects, particularly in the Toronto area. Industry experts say COR certification could eventually become mandatory for all commercial construction jobs nationwide.

The Certificate of Recognition (COR) program consists of workplace health and safety training courses and auditing procedures. COR training and certification is handled by provincial or territorial safety associations. These associations operate under the auspices of the Canadian Federation of Construction Safety Associations (CFCSA), a national umbrella group.

“COR is an evidence-based audit that validates [a company’s health and safety program] is actually being applied. It gives basic confidence to the buyers that the contractor I’m going to hire to do this project, I know they are applying the program, so I don’t have to worry about work stoppages and people getting injured on the site,” says Paul Casey, vice-president of programs and strategic development for the Infrastructure Health and Safety Association (IHSA), in Mississauga, Ont.

Casey points to a recent study by the Partnership for Work, Health and Safety that found reduced rates of injuries at B.C. construction firms with COR certification.

“As time goes on, more and more buyers will be asking for COR as a pre-qualification … [eventually] the entire sector will be involved with COR,” he states.

There’s plenty of evidence to back this up.

The Toronto Transit Commission (TTC) has announced it will be requiring COR certification for construction contracts greater than $5 million, starting July 1, 2016. On January 1, 2017, this will expand to include contracts of any size. The TTC already requires COR certification for projects bigger than $25 million.

Metrolinx, an Ontario government transit agency, has followed a similar path. Starting April 1, 2016, Metrolinx will insist on COR certification for companies bidding on construction projects worth $25 million. COR certification is slated to become mandatory for all Metrolinx projects this fall.

Infrastructure Ontario (IO) is a crown agency that partners with non-profit groups, crown corporations, municipalities and

provincial ministries to renew infrastructure in the province. Infrastructure Ontario now requires lead construction contractors at companies receiving alternative financing and procurement contracts from the agency to be COR certified or in the process of being certified.

In early 2016, the City of Toronto announced it would require COR certification for contractors working on construction projects worth more than $25 million, beginning January 2017. The COR requirement will be extended to all City of Toronto construction contracts by January 2019.

COR training and certification in Ontario is handled by the IHSA. In the four years since COR was introduced in the province, 680 companies have registered for the program and 124 became COR certified. Most of these firms are in construction, says Casey.

The IHSA aims to have “10,000 companies registered in a program and at least 2,000 certified,” within a few years, he adds.

In Nova Scotia, 25 per cent of construction firms representing 65 per cent of the workforce have COR certification.

on-sitemag.com / 29

ONS_APRIL2016_GHW.indd 29

2016-04-14 10:33 AM

SAFETY This is up from roughly 21 per cent of firms five years ago, says Bruce Collins, general manager of the Nova Scotia Construction Safety Association (NSCSA) and president of the CFCSA. The Alberta Construction Safety Association (ACSA) has 60,000 members covering residential, commercial and industrial construction.

“About 10 per cent of that group, 5,000 companies” representing 60 to 65 per cent of the province’s construction workers, have COR designation, states Tammy Hawkins, chief operations officer of the ACSA in Edmonton.

The number of Alberta employers in all sectors who are COR certified has grown from 1,400 in 1998 to 10,722 in 2015.

The COR program originated in Alberta in the early 1990s as a provincial workplace safety and health initiative. Nova Scotia embraced the concept next, making COR a pre-qualifying factor for tendering construction contracts on January 1, 1996.

Today, “most public, but not private” commercial construction projects in Nova Scotia require COR certification, says Collins.

COR took on a national character after it was endorsed by the CFCSA. During meetings in the 1990s, CFCSA representatives agreed on minimum national standards for COR certification and training. As more provinces and territories embraced COR, the CFCSA helped forge a reciprocity agreement making COR certification from one province or territory valid in other jurisdictions, says Collins.

Quebec doesn’t offer COR training but it does recognize COR certification from other provinces and runs its own workplace health and safety program. Prince Edward Island doesn’t have a provincial safety association, so commercial contractors on the island receive COR training and certification from groups in Nova Scotia and New Brunswick.

HOW DOES IT WORK? Casey explains how COR certification works in Ontario. The process is generally the same across the country. First, a company fills in a COR application from the IHSA. Once the application is accepted, a senior

manager takes a ‘COR essentials’ course that covers workplace liability and health and safety measures. A second, permanent full-time employee takes the same course plus additional lessons on auditing, occupational health and safety legislation, etc. Courses generally take half-a-day to a full day to complete.

While the main elements are the same, there is some variation in training from province to province. Ontario, for example, recently added a course on hazard and risk management.

Following training, the employee who took the auditing courses conducts an internal workplace audit. This involves interviewing staff, reviewing documents and inspecting the workplace. Companies are marked on how well they live up to COR standards in terms of safe work practices, protective equipment, preventive maintenance, emergency preparedness, first aid, violence and harassment policies. The results are submitted to the IHSA for review. Once the review is done, the IHSA arranges a thirdparty audit to confirm the initial findings.

A company that scores 80 per cent overall on the audits (and no lower than 65 per cent on each category) receives a Certificate of Recognition (COR), valid for three years provided the firm does internal maintenance audits in the intervening years.

The IHSA charges between $80 to $160 per person for the COR essentials course when taught at an IHSA facility. The IHSA’s hazard and risk management course costs between $160 and $320 per person, at an IHSA facility. Fees are steeper if a course is

offered at a worksite. The IHSA charges $575 for reviewing a company’s internal audit and $1,150 a day for third-party auditing. These prices come from the IHSA’s website.

In the long run, COR might actually help companies save money. COR-certified firms in Alberta, for example, paid out 38 per cent less in workers’ compensation in 2013 than non-COR holders, says Hawkins.

The Partnership for Work, Health and Safety, an alliance between the University of British Columbia and WorkSafeBC (B.C.’s Workers’ Compensation Board), studied the impact of COR for the period 2005 to 2012. “[COR] certified firms in construction and forestry [in B.C.] had, on average, 12 per cent and 16 per cent lower short-term disability, long-term disability and fatality rates and 16 per cent and 21 per cent lower serious injury rates compared to non-certified firms, respectively,” stated the Partnership for Work, Health and Safety report.

According to the study, the number of B.C. employers in all sectors taking COR leapt from nearly zero in 2003 to over 3,500 in 2011—more evidence of the program’s growing popularity.

“I absolutely believe COR certification will become the standard across the construction industry, especially on the largest projects.

We already see that happening, with many major buyers of construction adopting it,” says Lawrence Quinn, senior vice-president, project delivery at Infrastructure Ontario.

CRMCA: Insuring wood structures | 34 Gas Saws

2016-04-14 10:33 AM

INSURANCE AND CONSTRUCTION COSTS OF WOOD STRUCTURES

T

he push for increased use of wood for high-rise buildings has raised several issues beyond constructability. The wood lobby has a high profile within government organizations, including the provision of subsidies. Consequently, it has also achieved a highly successful and visible campaign to increase the share of wood in high-rise buildings.

The presentations that are being delivered in all parts of this country on the benefits of wood are well balanced on the technical side. This refers to details outlining constructability related to moisture protection; fire resistance; air tightness, energy performance, etc. The more contentious marketing has been conducted on the economic considerations. They claim the six-storey wood frame is more cost effective than wood or steel. With limited construction experience with this type of building and the higher storey ones being constructed in British Columbia and Quebec under subsidies, the reality of being more cost effective isnâ&#x20AC;&#x2122;t clear.

SCOUTING THE COMPETITION The Concrete Council of Canada (CCC) is looking at the issues surrounding this latest competition to its industry, and questioning its claims. The first piece in addressing constructability is the real cost of insuring these buildings during construction and once they are complete. As a result, they commissioned a study with a group called the Globe Advisors, a Division of the GLOBE group of companies.

The study analyzed the costs to insure mid-rise (six-storey) wood frame residential buildings, with particular emphasis on the risk factors contributing to differentials between insurance rates for such buildings compared to structures built using various noncombustible materials such as cast-in-place concrete, insulated concrete forms, precast concrete, or concrete blocks. To read the full Study of Insurance Costs for Mid-Rise Wood Frame and Concrete Residential Buildings, visit: http://globeadvisors.ca.

In summary, they looked at the two key demands that were driving this change in the marketplace, namely the political will to increase the use of wood in Canadian construction; and the market need for more affordable housing in major city centres.

They identified that builders are continually seeking to maintain their margins, but in major centres such as Vancouver and Toronto, serviceable land is at a premium, so there was pressure

for more affordable options to be considered, such as expansion in the use of wood frame for higher stories. This provides a solution that would meet the need for higher densities and more affordable construction. The authors are quite clear that this study did not address the actual construction costs but rather the insurable side of the business. They do point out if life cycle considerations were part of any assessment it would provide a different argument for material selection.

The insurance considerations were mainly to address the differential between the materials for the insurance rates that would be levied during and post construction. Insurance rates are driven by fire risks, water damage, mould and other factors.

Higher wood frame structures may increase premiums, but the dominating factors are fire risk and water damage. As stated earlier the use of wood frame for larger buildings is still in its infancy, so insurance rates for use of the technology is not readily available. However, the insurance risks for fire and water damage are well known. The authors also point out that the initial costs for any type of building are only 10 to 15 per cent of the total lifecycle of the structure.

In line with the rising cost of housing, insurance premiums naturally follow suit. Underwriters assess premiums based on potential claims for policies in a year. They will limit their exposure in different markets or classes of buildings. The report summarizes discussions with brokers, underwriters and property managers who deem a substantial difference in wood-frame buildings compared to similar buildings constructed out of noncombustible materials. The reasons cited for this differential were the higher risk of fire, and repair of water and moisture damage to wood structures.

If all considerations were equal for a wood structure versus a concrete structure, experts estimate that the insurance costs for wood would be 10 times more expensive. Climate change and the impact on structures will start to play an important role in the setting of insurance rates as resiliency becomes an issue in the future.

Another note in the report outlines the concern for the limited ability to insure wood buildings based on previous experience. In B.C., in particular, the last major water and moisture failure resulted in the B.C. Warranty Program shutting down and the insurance industry backed out of the province.

The report speaks for itself, and as stated earlier, it is the first piece in addressing the issue of costs with the six-storey wood frame promotion. The CCC is working toward the correct information for the field so the client can make the appropriate and informed decision.

hen it comes to choosing a heavyduty, gas-powered, hand-held cut-off saw, size is not always the determining factor, manufacturers agree.

“The high-speed gas saw is one of the most used, and abused, pieces of equipment on any job site,” says Paul Edwards, product engineer with Norton/Saint-Gobain.

“You have got to have a tough, easy to use, reliable one to help get the job done.”

What concrete contractors are looking for in this workhorse hand tool is overall reliability, including easy maintenance and one-pull starts. When on the job site, you don’t want to have to worry about getting the right choke setting or if dust is clogging up your air intake and reducing performance.

And the easier it is to adjust or replace drive belts, pull cords and air filters, the less downtime there is.

“Those are some of the most common

concerns,” agrees Husqvarna product manager Mike Ward.

Ergonomics also play a factor in the design and handling of cut-off saws. When making precision cuts, you want the tool to be properly balanced for its size and easy to use. Reducing vibration and engine noise when at full throttle are other key areas to be considered when checking the tool specs.

“We are also continuing to see growth in tool rental market as a way of trying new tools prior to the decision to purchase,” adds Joe Taccogna, senior product line marketing manager with ICB, whose products include the unique concrete cutting chainsaws.

Many of the recent upgrades to the tried and true cut-off saw designs revolve around easy-start initiatives. Automatic chokes, electronic fuel injection, automatic fuel mixing for optimum performance and improved air flow designs are all part of the equation depending on the manufacturer.

Here is a closer look at five of the industry’s leading cut-off saws:

HILTI DSH 700/900-X Cold and warm start procedures have historically been some of the most frustrating user-experiences with two-stroke engines.

Hilti took it to heart with its next generation of cut-off saws and developed the ‘Easy Start’ technology that automatically sets the proper amount of choke for more first-pull starts and less engine ‘flooding’, says David Walker, Hilti’s Diamond Systems business unit manager.

“We’ve added an auto-choke system to our new DSH 700-X and 900-X gas powered saws, which eliminates the need for the customer to worry about choking the saw or selecting the right amount of choke for each start,” says Walker. “You just simply flip the switch ‘on’ and pull the starter rope.”

To defend against dust and debris, Hilti units use a Cyclone Air Filtration System to remove particulate from the engine air intake flow by way of centrifugal force. The cleanest air is suctioned from the center of the cyclone and then sent to the physical filtering system.

“This dramatically increases the filter’s lifetime and performance, meaning less downtime for contractors,” notes Walker.

The DSH 700-X is a 70cc saw and is available in 12- and 14-in. models, while the DSH 900-X is a 90cc saw in 14- and 16-in. models. On-site maintenance for both is made simple with an easy-to-access and change starter rope, air filter housing and a reinforced blade guard.

NORTON CLIPPER When designing the Norton Clipper, engineers found solutions to the everyday customer concerns of using two-stroke motors and high-speed saws. The 3-step easy start eliminates the hassle of a choke.

The electronic carburetor’s electro-magnetic valve eliminates the standard choke and

half throttle start. Operators simply turn the switch on, prime the engine, and push the decompression button, and pull the cord.

Using the patented iLube system, measuring oil and premixing is eliminated as “the machine does it for you,” notes product engineer Paul Edwards. An automatic idle function kicks in when the oil reservoir is low and needs refilling. This prevents damage to the 5.4 hp engine. The Clipper remains neutrally balanced when cutting in any angle over a 180-degree radius. Ergonomic designs have eliminated the familiar gyroscopic effect of torqueing up and to the right when throttling up.

“Overall, it is just a better balanced machine,” notes Edwards, adding the vibration reduction system also improves ergonomics.

The multi-stage air filtration system with external rocker wheel adds to operating efficiency and extends machine life. Twin-air inlets draw fresh air in from the back of the machine and create a natural internal cyclonic effect forcing out larger particles.

Air then passes through a two-stage main and micro filter process. When on idle, the external rocker wheel vibrates the filter to further help release debris. This system extends the filter life and improves performance. The Clipper comes in 12-in. and 14-in. models.

HUSQVARNA K970 The upgraded K970 is one of Husqvarna’s workhorses in the cutoff saw line. The most recent model features an upgraded engine platform that meets lower emission standards.

“It is more fuel efficient and runs cooler, which provides longer engine life and more dependability,” says Mike Ward, Husqvarna product manager. Used extensively by road contractors for curb cuts, the K970 can also

be attached to a trolley. The wet cutting kit provides excellent dust control and features less slurry and low water consumption because of a redesigned water valve that automatically adjusts.

“Less water means less clean up and less environmental concern,” notes Ward.

It fits 12 in. to 16 in. discs and multiple blade bushings thanks to the reversible blade bushing design. An anti-vibration system in the cutting handle allows for more comfortable long-term use. The drive belt and transmission is fully sealed to help keep out cutting dust. Likewise, the dust sealed starter, return spring and pulley bearing combined with optimum ignition timing provides virtually maintenance-free starting.

The reversible cutting arm allows for closer cuts to walls and the ground. The K970 puts out 6.5 hp and weighs 24 lbs.

ICS 695XL For something a little more non-traditional, the ICS 695XL concrete cutting chainsaw strikes a very different profile.

“ICS started as a product development project more than 25 years ago and we really invented the category of concrete chain saws,” explains Joe Taccogna, senior product line marketing manager. ICS also invented and patented a technology that seals out the abrasive slurry that plagued early diamond chains with stretching of chains. Productivity is key, says Taccogna.

“This can mean many things from improved cutting speed to reduced downtime.”

The latest version of the 695XL has a new piston and cylinder design that lowers engine temperature and improves cooling, resulting in longer engine life and less downtime.

“The primary advantage of a chain saw in cutting concrete, masonry and stone is the depth of cut with a fairly small opening size,” explains Taccogna. It also facilitates

cutting square corners without having to overcut.

“There are some openings where there is simply no other tool that will do this job.”

With a chain saw, you can make a cut all the way through a 10-in. wall and make an opening as small as 4 in. by 4 in. without over-cutting the corners, Taccogna explains.

ICS offers gas, air, hydraulic and highfrequency electric powered saws outfitted with 12-in. to 16-in. guidebars.

The TS 420 is a mainstay in the Stihl line-up of cut-off saws. “Our customers are still looking for a quality tool that will get the job done, day-in and day-out, and offer versatility,” notes Chad Dubois national manager, Technical Services for Stihl. “The secret to its longevity is the combination of engine design with reduced emissions and fuel consumption, state-of-the-art air filtration system and an effective anti-vibration system,” to name a few of the stand-out features.

The TS 420, with the standard 14-in. disc can be hand-operated or mounted on the FW 20 cart (sold separately) for improved precision and comfort. The semiautomatic V-belt tensioning system allows for light, consistent re-tensioning that increases the service life of the belts and shaft bearings. A compensator controller in the carburetor maintains the constant ideal fuel-to-air ratio for ideal engine performance as the air filter begins to get dirty. The ElastoStart pull cord reduces the shock in user’s joints and muscles caused by the compression of the engine during starting.

Stihl is the first manufacturer of hand-held power equipment to introduce electronic fuel injection in its TS 500i. The system allows for greater fuel economy, less harmful emissions and improved performance The TS 500i is able to stay properly tuned in every operating phase, eliminating the need for manual adjustment. It also features an electronic watering system that has seven levels of water output and shuts off when the machine comes down to idle, notes Dubois.

EDMONTON SCORES WITH LEED SILVER ARENA 24,000 cubic metres of concrete and 9,000 tonnes of steel are being used in this building.

BY ROSS MONSOUR

T

he Rogers Place Arena in Edmonton is a testament to the long-term durability of concrete, and the advantages that this material brings to mega structures. The arena will be unique in the sporting industry as the first NHL facility designed and built to meet LEED Silver designation.

It will consist of the major sports arena that includes seating for more than 18,000 hockey fans, and over 20,000 for other major events. It will have a community rink attached and a Winter Garden complex as the entrance to the arena.

The complex will include a 47,800-sq.ft. community rink, 33,800-sq.-ft. Winter Garden for public gatherings, 182,000sq.-ft. underground parking garage and a 22,800-sq.-ft. corridor.

The construction partners on this project are the City of Edmonton; primary owner Katz Group who own the Edmonton Oilers; the ICON Venue Group who are the

project managers; PCL is the construction manager and HOK is the architect (HOK purchased the original firm of 360 Architecture).

The construction work started in 2013 and is expected to be complete

by September 2016, just in time for the beginning of the hockey season. The estimated cost for the facility and the connections to the City infrastructure is $606 million. The City will be responsible for connecting the LRT and a pedestrian walkway to the Rogers Place. The contract is not a typical design/build process but rather a Guaranteed Maximum Price (GMP), which maintains the contract at fixed price unless design changes are made after the contract is under way.

Construction started in July 2013 with pile loading testing at two sites. These were excavated, concrete piles were placed and steel beams were loaded on them to test the piles performance. During this

excavation the soil was left on site to minimize truck traffic. The soil was covered to minimize the dust in the area. Concrete trucks accessed the site to cast the piles. After the piles were tested the soil was backfilled into the excavated area.

The actual excavation started in March 2014 with 80,000 cubic metres of material being removed. This was the start of a process where 700 concrete piles were cast for structural support of the complex. Once the piles were complete, the remainder of the concrete and steel structure began in September 2014. The building is being constructed with 24,000 cubic metres of concrete and 9,000 tonnes of steel.

Aspects of the build that assisted in qualifying it for LEED Silver accreditation were 94.8 per cent diversion of waste from landfills totalling 3,469 tons; other areas are LED lighting and the connection to the transit system. This facility will use heat recovery ventilation combined with a highly insulated building envelope.

Another unique feature is that the ice slab is cast on top of a 16-in. structural slab that is over the underground parking. The arena slab itself is 8-in. thick and the application took 320 cubic metres. Under the mesh are miles of cooling pipe that will cool the ice using the radiant mass of the concrete. There are about 129 zone for the cooling pipes. The concrete was placed in 12 hours followed by 12 hours of finishing. The curing was conducted over a month using a wet cure covered with polyethylene, which is optimal for this type of slab.

This project is part of the revitalization of the Edmonton downtown and establishes a benchmark for future structures in the City.

DEVIL IS IN THE DETAILS Nearly 40 cement trucks were needed to complete the project, with more than 320 cubic metres of cement being poured (approximately one-half of a kilometre of standard city sidewalk).

“This is definitely a milestone,” Trevor Sundquist, structural superintendent for PCL Construction, commented on the pour.

Below the eight-in. ice slab is another 16 in. of concrete structural slab sitting overtop the parkade. Most ice slabs are poured on a sub-base made of clay and gravel, explained Sundquist, however Rogers Place is “one of very few in the NHL” that will sit atop a parkade.

“There was a lot of engineering that went into this,” said Bob Black, chief project development officer, OEG. “We expect to have many exciting moments in the future on this surface.”

RISK

By David Bowcott

Invest in innovation to drive productivity and lower risk

F

or as long as I can remember the construction industry has been hammered by academics, government and business leaders for having low productivity measures compared to other industries. The sector has also been criticized for poor productivity – being amongst the lowest ranked in developed countries. I’m not entirely sure the measures being used to determine productivity are entirely appropriate, but I do believe there’s a great opportunity for the Canadian construction industry to improve.

THE QUESTION IS: HOW? There are many ways the construction sector could improve its productivity. However, an investment in innovation has the potential to be the most potent. Some may call it investment in research and development (R&D), but whatever you call it, if a company, or an industry invests in new ways to deliver their offering to the economy, they often find it leads to improvements in productivity too.

So how much is the construction industry currently investing in innovation?

The table below outlines the construction industry’s innovation investment in comparison to other sectors.

Sector

It doesn’t take a statistician to devise that the construction industry is well behind in terms of investing in better ways to deliver their offerings. This is a tragedy, and it MUST be rectified. Though the industry is delivering great value to owners and investors, there’s an opportunity to further optimize the way we design, build and operate assets in today’s Canadian construction economy.

GET INVOLVED Key trends within the global construction economy (globalization, lifecycle asset management, investigation into new delivery models) are creating even greater demand for innovation. The timing of initiatives like the Canadian Construction Association’s CCI Advocacy Program is perfect.

Formed a couple of years ago, the Canadian Construction Innovation program could help Canada become a world leader within the global construction and asset management economy.

CCI’s mission is to instill a new culture for research and innovation in the Canadian construction industry.

If you are not aware of CCI, I strongly encourage you to visit their website - www. ccinnovations.ca/.

There is little doubt that investment in

innovation and research within any industry invariably leads to improved productivity and profitability for industry participants.

As you know I’m in the risk game, and so are you, and though productivity and profitability are prime benefits of investment in innovation, there should also be more discussion around the linkage between this type of investment and the lowering of risk.

Those of us within the risk industry need to take a leadership role in the efforts of CCI and the CCI Advocacy Program.

FINANCE INNOVATION The insurance sector spends millions of dollars within the construction industry on risk engineering in order to proactively manage risk, so why on earth wouldn’t it consider financing innovation and research that can lower risk on construction projects (and the resultant operating assets)? The insurance sector should, and I expect will, step up and support CCI and the CCI Advocacy Program, in order to lower risk and create a more fertile environment for profitable underwriting returns.

Ultimately, it would benefit all sources of capital that goes into a project, not only insurance capital, to investigate this association and its initiatives in order to gain more certainty around their investments (ie., the project finance community)

Dolvin made no claimants about a bond, the owner must such demand upon TTC, however, until it was know who they are and would therefore have too late. Dolvin also argued that TTC’s silence to investigate and maintain a constant watch on the bond’s existence (until specifically of all work and materials used, and labourers asked) was misrepresentation. This argument involved, onsite. Furthermore, no such duty failed as well. Although Dolvin made no valid was specifically set out in the bond, nor was demand to TTC, it made a valid and timely there evidence of any such trade custom. demand for information about a bond to the However, if a claimant requested information general contractor.

The same point arose recently in Dolvin These issues came up again in Valard

Construction Ltd. v. Bird Construction Co., where an unpaid sub-subcontractor, Valard, failed to give timely notice under an L&M bond. Valard unsuccessfully tried to argue that as trustee, Bird Construction owed a duty to inform it about the bond. The “trustee” language in the bond was there only to identify who would be claimants under the bond. It was not there to add additional duties to the “trustee”. It is the obligation of unpaid potential claimants to ask about whether a bond exists.

Whether this is the final word on these issues remains to be seen. Law reform might one-day change whether owners or other “trustees” have to make positive disclosure of L&M bonds absent a specific request. Publication of these bonds, perhaps by posting a copy on site, could reduce the possibility that the bond will be ignored by valid claimants (this is already statutorily required for Alberta public works).

It is even possible that the developing duty of good faith in performing contractual obligations may create obligations of disclosure in ways that cannot currently be predicted.

Whatever the future holds on these issues, it is clear that unpaid subcontractors and suppliers significantly increase their options for recovery by making timely and specific requests to the correct parties about available payment bonds.
