Clark Builders has been working on a four-storey, 19-unit public housing project on Moyle Drive in Yellowknife, initiated by NWT Housing Corporation. Construction expected to shrink 20 per cent by 2020 More people working but territories still struggling to compete with southern companies by Meagan Leonard Northern News Services NWT/Nunavut According to the latest economic forecast from the Conference Board of Canada, the NWT construction industry employed an average of 1,985 workers in 2014 – up two per cent since 2009. This represented approximately seven per cent of the total workforce. However, this number is anticipated to contract by 20 per cent by 2020 as construction wraps up this year at the Gahcho Kue diamond mine, the Inuvik to Tuktoyaktuk Highway and the Mackenzie Valley Fibre Optic Link. Smaller projects which will provide slight relief include the Diavik A-21 pipe and Ekati's Jay Pipe project, which is scheduled to start construction by the end of the year. A boost to the industry is anticipated when Avalon Advanced Materials begins development of its Nechalacho property and construction begins at the Prairie Creek and NICO properties. In Nunavut, construction accounts for 13 per cent of the territory's economic activity and has contracted by about a fifth, according to the report – largely as a result of the Mary River mine completing its development phase. In 2015/16 there were 810 employed by the industry; however, the majority were fly-in, fly-out workers. Promising projects include development of Agnico Eagle's Amaruq deposit and construction of its $1.2 billion Meliadine gold mine which is expected to take three years and give the industry an 18 per cent boost. NWT and Nunavut Construction Association (NNCA) vice-president Jack Rowe said project focus for the territories varies from year to year and typically follows a departmental trend but the overall amount of construction has remained relatively consistent. Currently in the NWT, he said, the demand seems to be for health care facilities, whereas a few years ago precedence was given to schools. Because so much of the territory's infrastructure requires upgrades and rehabilitation, he said the government seems to be tackling one sector at a time. "We've seen a new health facility in Fort Providence, a new health facility in Hay River – there's a new one going in Norman Wells right now, there's a new one going into Fort Resolution and of course Yellowknife," he said. "They probably looked at their requirements and tried to focus on replacement of assets and also maintenance." In Nunavut the trend is See Industry, page 5 NNSL file photo Construction on Iqaluit’s $40-million aquatic centre was delayed last summer because of ice conditions blocking the sealift but it has been going full-throttle since then.

The Government of Nunavut directed more than $77 million for construction in its 2015/16 capital spending plan. by Meagan Leonard Northern News Services Iqaluit Iqaluit's new $300 million airport is still scheduled to open in August 2017, despite a few hiccups over the past year. Those visiting the site will now notice a number of additions – a large sweeping terminal building being the most obvious. Construction of that structure was set back last year after a roof fire caused $1 million in damages Sept. 5. Airport director John Hawkins said the blaze started during some torching work and affected approximately 10 per cent of the roof. Although it was contained, the destruction was extensive enough to require replacement of the Styrofoam insulation layer. He said engineers and contractors sealed it for the winter and repairs are scheduled to be completed after a sea lift arrives this spring, adding they will not know the full extent of the damage until it is inspected at that time. "There's potential for water or other damage to kind of migrate underneath what's visible, so they'll do some testing of that," he said. Costs incurred will be covered by the Government of Nunavut's private partner PPP Canada, not borne by taxpayers and it is not expected to affect the overall construction time line, said Hawkins. "The interior work was all carried on, so there will be some additional work but it can all be carried on concurrent with other work," he said. "It won't put the schedule back." Another worry came in October when the last sea lift of the season departed before its cargo could be fully unloaded due to early-forming sea ice on Frobisher Bay. Hawkins said luckily they had enough asphalt leftover to continue with scheduled work. "The ice is something you have trouble anticipating," he said. "There was enough (asphalt) in town and on site that it will not impact their start up of paving next year – by the time they start that up the ships will be arriving again." Last year, two new taxiing lanes were constructed leading from what will be the new main apron out to the runway, along with significant expansion where the terminal is located. The combined services building was also erected and closed in and interior work has began. Construction has begun on some airport movement surfaces, taxiways and aprons along with crushing, blasting and making aggregate for asphalt production. A culvert to divert a stream in front of the terminal building was also completed, said Hawkins. PARKING APRON TO BE EXPANDED This year, expansion of the apron – an area where planes are parked, loaded, boarded and refueled – will be completed, tying it to the northend of the runway and taxi way. The taxi way, connecting the runways, apron, hanger and terminal, is also scheduled to be repaved. Repairs and excavation to the current apron will be completed once the new additions are operational. Hawkins estimates most ground work will be finished in 2016 and the remaining structural work early next year. "We expect the buildings by this time next year will be in the curation process, so all the systems will be in and operating and tested and verified," he said, adding services will be transferred to the new terminal next summer. "Passenger operations should begin in August." Estimated to be completed by late summer next year, the project features a new airport terminal, expanded plane parking, new lighting systems, an upgraded runway and a combined services building to house fire-fighting vehicles, snow plows and other heavy equipment. Unlike the old terminal, the new 100,000-square foot building will have the terminal and parking lot on the same level, negating the need for the multiple staircases present in the old design. Washrooms will also be added for passengers who have already passed through security, along with an additional baggage carousel. The public-private partnership (P3) is being funded by Nunavut, ($68.7 million), Public Private Partnership Canada ($77.3 million), and the remainder by business group Arctic Infrastructure Partners – a consortium comprised of InfraRed Capital Partners Ltd., Bouygues Building Canada Inc., Colas Canada Inc., and the Winnipeg Airports Authority. The group will construction and operate the airport with the Government of Nunavut making payments for approximately 30 years – at which time it will assume full ownership. Approximately 20,000 arrivals and departures move 140,000 passengers a year through the city. fact file Summary of economic development and transportation capital expenditures by region Region Headquarters Qikiqtaaluk Kivalliq Kitikmeot Total Amount $63.3 million $0 $3 million $2 million $68.3 million Nunavut transportation projects Capital estimates Small craft harbours $500,000 Iqaluit International Airport improvements $59.8 million ($77 million 2015/16) Taloyoak air terminal building $2 million Transportation equipment and facilities $1.7 million Small capital ($250,000 or less) $800,000 Kivalliq Regional Visitors Centre $3,000 Percentage of Nunavut capital spending by department - April 1, 2016 to March 31, 2017 Department Percentage Culture and Heritage 0.3% Family Services 0.3% Office of the Legislative Assembly 0.4% Environment 1.6% Justice 2.3% Finance (NAC) 3.0% Health 8.4% Education 13.4% Community and Government Services 16.2% Nunavut Housing Corporation 19.4% Economic Development/Transportation 34.7% Source: Government of Nunavut NORTHERN CONSTRUCTION 2016 NEWS/NORTH, Monday, April 25, 2016 5 Projects change with the climate As permafrost melts, new construction standards are being developed by Meagan Leonard Northern News Services NWT/Nunavut Construction companies in northern communities now have a new set of standards for infrastructure development in regions affected by climate change and permafrost. The Northern Infrastructure Standardization Initiative, a $2.5-million project spearheaded by the Canadian Standards Council, involved consultation with industry experts to determine the effects a warming Arctic would have on current and future buildings. Mike Burns, assistant deputy minister of Public Works and Services, was one of the project's contributors and says one of the main challenges they're seeing in the territory is increased precipitation and heavier amounts of snow accumulating on building roofs. Over time, this increases the chance of structural collapse and damage to communications equipment, in addition to interior leaks and mold. Burns said when they began inspecting buildings in the territory to determine whether they would be able to withstand a larger snow load, they found up to 18 at risk. "We went in and we improved the roof structure in those buildings and beefed them up to deal with a potential increase," he said. "There's more snow in the North than there used to be but you can actually see it and measure it." When it comes to people's perception of how buildings are affected by climate change, Burns said most envision crooked structures sinking into the ground. In reality, he said this phenomena is usually the result of aging infrastructure used past its lifetime resulting in rotten wood foundations. "It wasn't a case of they were failing due to permafrost, they were failing because they were past their useful life," he said. "Some of what you're seeing on the foundation side might be more related to the aging of buildings." Over the last few years Burns said work has focused on measuring precipitation and permafrost degradation to determine the rapidity of change so new standards can be applied to future infrastructure. The result of this work has been the development of four new standards for use in the NWT around thermosyphon supported foundations, heavier snow loads, permafrost degradation and community drainage. THERMOSYPHONS FOR REFRIGERATION Thermosyphons refrigerate the foundation of buildings constructed on steel or wood piles through a heat transfer system. Burns said the challenge is ensuring the technology can keep pace with the rate the permafrost is thawing. "If it starts getting warmer than was anticipated the system might not have the capacity to keep the building stable," he said. "We looked at developing standards so … (people) will have the tools to project the capacity of that system and keep it stable for the life of the building." photo courtesy of the Department of Public Works Climate change has led to changes in the composition and accumulation of snow in many NWT regions. The increase of heavier snow requires additional maintenance and building design measures be taken. The standards also aim to address techniques for dealing with permafrost in the past, which are not effective in today's environment. For example, many people used to push snow around their homes to keep the heat inside. "Unfortunately what this does is keep the cold air out from under the buildings in (those) that are elevated and therefore doesn't allow the cold to penetrate as far down as it should and keep the permafrost frozen," he explained. Drainage, when left uncontrolled, can also do significant damage to a building in the North. "If it gets in and around a building that's got a permafrost foundation, it can easily deteriorate the permafrost or cause it to thaw or cause the building to lose its foundation," he said. Thirty years ago, buildings were not constructed with climate change in mind, Burns explained. The active layer – the top area of soil that thaws each summer and freezes again in the fall – was much shallower. To ensure buildings remain stable, wood or steel piles are frozen into the permafrost below the active layer. When this zone thaws in the summer, it grabs the sides of the piles and attempts to force them upward. As long as the piles are deep enough, the frozen ground counteracts this shift. However, as the active layer becomes deeper, the amount of heaving becomes exacerbated and piles must be buried deeper. With old infrastructure, this becomes problematic, says Burns. "Originally, you might have had two thirds of your piles below the frozen ground and one third in the active layer and above the ground," he said. "If that changes dramatically and you go 50/50, now you have a lot more upward force on the pile trying to lift it and the amount you froze in the ground may not be able to counteract that anymore." He said under the new standards, builders are required to go 30 to 40 per cent deeper for pile foundations – they are projecting at this level, a structure will remain stable for up to 50 years. They are also adding mechanical freezing technology to piles to help offset melt in the event climate change happens more rapidly than expected. In terms of implementing the new parameters, Burns said he does not anticipate it will affect the overall cost of construction in the North. He said recent strides made in infrastructure energy efficiency will reduce operating costs and therefore offset the minor capital costs of new buildings. Most simply need to be replaced because they are old, he said. "If the buildings are at the end of their useful life anyway and due for replacement, then there wouldn't necessarily be a cost," he said. "We would incur more in the cost of the foundation for that building but we've also reduced the energy costs." Burns said there will be an upcoming training session on the new construction standards held in Yellowknife by the Canadian Standards Association where communities, municipalities and government will be provided with information on how to apply the new standards to upcoming projects. Industry tackling one sector at a time Construction, from page 3 toward large-scale public sector initiatives such as the $143-million Canadian High Arctic Research Station in Cambridge Bay and transportation projects such as the Iqaluit air and marine ports. A new $40-million aquatic centre is also being constructed in Iqaluit and is scheduled to wrap up in 2017. He says they have also seen a lot of community infrastructure upgrades, including the construction and repair of public housing units. "In Nunavut they've got a mixed bath, they've got some federal projects … but they also have a lot of housing projects and … a lot of upgrades to infrastructure," he said. He said they are gradually seeing more Northern companies take on projects, especially in Nunavut. Last year, he said the association worked closely with the departments of Public Works and Industry, Tourism and Investment to make changes to the Business Incentive Policy – a program that gives preference on government procurement to businesses owned and operated within the NWT. BUSINESS INCENTIVE POLICY Registered companies can receive a favourable bid adjustment over non-BIP companies. The bid adjustment is based on the value of the contract with up to 15 per cent eligible for contracts up to $1 million. Many local organizations – including NNCA – have been lobbying the government to change the 20-year-old policy and develop a new system of awarding contracts. Rowe said they wanted to ensure changes to the legislation would not affect its overall purpose. "You'll always be measured by your success or failure of your ability to retain the benefits but there's some things that may or may not be able to be done in the North," he explained, adding not all services are currently available here which requires going south for some projects. "If people identify there's something being done in the south or stuff they're doing in our neighbouring jurisdictions is being imported, maybe that's an opportunity for a Northern business." He says competition with southern jurisdictions remains the industry's biggest challenge – especially as Alberta's economy slows and there is a larger number of companies looking for tenders. Rowe says a smaller amount of available funding from the GNWT will also affect which projects are able to move forward in the near term. "The marketplace is slowed up in most of the jurisdictions in southern Canada and so it's a pretty easy market to bid into," he said. "There's been no secret made that they're talking about $150 million cutback, that probably tells you that larger capital projects photo courtesy of Clark Builders The steel structure goes up at the Northwest Territories Geological Survey's new geological storage facility in Yellowknife. Located near the airport, this facility will house geological collections, including 12,000 boxes of drill core donated by industry, thousands of rock, stream and lake sediment samples, and glacial till samples. will probably be delayed or re-profiled." Looking forward as some of the current projects wrap up this year and next, Rowe says he would like to see a shift to enhancing energy infrastructure. "We're hoping to see an expansion on the hydro," he said. "We're hearing that Saskatchewan might draw power off the Taltson system … where are we at for that?" Although the economy and Northern construction industry has not been viewed with optimism lately, Rowe says the territory has made great strides over the last two decades, particularly in terms of training and hiring its own workforce, and the evidence is apparent in many communities which have seen improvements to their stan- dard of living and availability of services. "Look at a place like Behchoko and look at the community pre-(mine) and now – it's a whole different dynamic," he said. "If you drive around the community, there's more places with a Ski-Doo and a boat and a new pick-up than there ever was so that tells me that we have more people working." NORTHERN CONSTRUCTION 2016 Two ports for Nunavut 6 NEWS/NORTH, Monday, April 25, 2016 Large harbour infrastructure projects in Iqaluit, Pond Inlet receive federal backing by Meagan Leonard Northern News Services Mittimatalik/Pond Inlet Iqaluit Two marine port projects have received the green light from the federal government and should begin construction some time in 2017, according to Nunavut's Department of Economic Development and Transportation. Iqaluit will see its $84 million deep water port come to fruition by 2020 after it was announced $63.4 million in federal funding would be allocated to the initiative. Pond Inlet will also receive $30 million to construct a small craft harbour. Both projects will have 75 per cent of their costs covered through the Building Canada community infrastructure initiative, with the territory required to provide the balance. Although construction of the Iqaluit port was originally scheduled to begin this summer, time constraints around environmental and regulatory approvals, along with preliminary geo-technical work have now pushed the start date back to 2017, said Jim Stevens assistant deputy minister. "We don't yet know whether we'll be able to do good geotechnical assessments on open water. We may have to wait until this fall to put a rig out," he said, adding the Nunavut Impact Review Board process will take a number of months. "There's still about six months of process that has to go and by that time we're basically back into the winter season and we can't do much in terms of construction." Nevertheless, he said once the legislative assembly approves its share of the funding in late March, the procurement process for engineering and environmental services will start immediately. Although he could not say the exact number of construction jobs the project would create, Stevens estimated it to be "in the dozens," adding contractors will be required to explain how they will maximize Inuit training and employment. The number of jobs will also depend on the construction method they decide on, he explained, as some of the work may be completed out-of-territory and shipped in later. SEVEN PORT DESIGNS In 2006, a proposal was developed for seven port designs – including Iqaluit – but the $41 million project was scrapped. Stevens said many of the elements from the original concept have been maintained, including a dock for single-vessel moorage and small craft harbour improvements. The design will also involve construction of a deep water port at the south end Polaris site and upgrades to the existing breakwater allowing increased dock space and 24-hour access to open water. An additional sea lift barge landing will be incorporated along with a lay down area for the sea lift. Stevens said this will require a significant amount of blasting as the existing small-craft facility will be overhauled and the area excavated to make way for floating docks and more boat access at low tide. "We have a tidal range here photo courtesy of the Government of Nunavut A diagram shows plans for the new marine port in Iqaluit set to begin construction in 2017. The project will include a deep water port and improvements to breakwater infrastructure which will make it easier to load and unload freight. of about 12 metres and at low tide vessels can't access water," he said. "We are anticipating excavation of a channel to get to open water during low tide." He said savings from the various upgrades will amount to around $1.5 million annually for sea lift companies as turn around time for supply delivery will decrease by about a week. He added cargo is often damaged or lost as it is being transferred to the smaller barges which bring supplies to shore. Stevens says he anticipates this will be reduced as well. "Right now all the re-supply is carried on barges from the mother ship to the shore and that is subject to tides, it's subject to ice problems, wind and waves," he said. "In some cases we've had ships stay here upwards of two-plus weeks waiting to unload. With a deep water port we anticipate a boat being able to get to the dock and taking a maximum of seven days to turn around." For the general public it means increased boating safety and easier access. "People will be able to get out into their vessels a lot better without kind of transferring through open water (and) fuelling will be a lot safer," he said. "There's a lot more com- fort to going to your boat that's tied up at a fixed dock verses moored out in the open water. Despite all but one of its 25 communities being located along the coast line, Nunavut has very little marine infrastructure. Currently only Pangnirtung has a small craft harbour with docking facilities – completed in 2013 to accommodate the local fish processing plant. SAFE HARBOUR FOR POND INLET Stevens said the Pond Inlet project will be similar to Pangnirtung in scope. "The principal objective is to provide safe moorage and harbour for our small craft vessels," he said. "It's a Northeast wind that seems to cause all the problems with ice and waves up there." The project would support economic development on Baffin Island while increasing food security and availability of fuel and other goods. Stevens said it will be espe- cially beneficial to the tourism industry as the community hosts a high number of cruise ships each year. "Right now cruise ships moor out in Eclipse Sound and transfer a lot of passengers via Zodiac boats to basically unprotected beaches," he said. "There have been occasions where passengers have to climb over rocks because that's the only area where the wind or waves are not affecting the beach that day." Approximately $10 million in funding would come from the territorial government; however, in order for the project to proceed, it needs federal confirmation. The lands in question are also currently owned by the coast guard and would have to be transferred to the Government of Nunavut. Pond Inlet MLA Joe Enook, who was part of the delegation, has been advocating for the port since 2013 when a storm caused thousands of dollars in damage to equipment in the community. NORTHERN CONSTRUCTION 2016 NEWS/NORTH, Monday, April 25, 2016 7 What is a P3 and how does it work? photo courtesy of the Department of Health and Social Services A rendering of what the new Stanton Territorial hospital will look like when complete in 2018. A public private partnership, or P3, is a procurement approach designed for large scale infrastructure projects. Under a P3, the private sector takes on a major share of the risks in terms of financing, construction, performance and long term maintenance. A government will specify what it is looking for, leaving as much scope as possible to the private sector which can then work to develop the most innovative design. In this way, the government does not pay for the project until it is built. Following construction, the private sector operates and maintains the infrastructure and the government pays a substantial portion over the life of the asset – but this is dependent on performance. Therefore if costs exceed projections, there are delays in construction or performance issues arise, taxpayers are not on the hook. This arrangement typically lasts 20 to 30 years, after which point the government may take over ownership and operation of the asset. In a traditional procurement bid, the government prepares detailed design specifications for a project and then tenders it to a contractor. With this model, the government assumes responsibility for any design flaws, cost overruns and delayed construction. The government is also responsible for the asset's operation. Governments tend to favour the P3 model for large projects because it allows the private sector to assume a greater role in the design, building, financing and operation of public infrastructure. It brings new expertise and innovation to projects and reduces the risks and costs typically borne by the government. Source: Public Private Partnership Canada Ground broken on new hospital Construction on $350-million project expected to be complete within two years by Meagan Leonard Northern News Services Somba K'e/Yellowknife Construction is well underway on the new Stanton Territorial Hospital after ground was broken on the $350-million public-private project last fall. The new facility, which will replace the existing Stanton hospital next door, is expected to be built within two years and fully operational by 2021. Original project plans described additions and renovations to the current facility which would have doubled its size over five years; however, last fall the GNWT revealed an entirely new structure would be constructed instead. "Construction on the new hospital … will see the current facility replaced by a new purpose-designed facility that will address patient needs and provide high-quality health-care delivery," said then-finance minster Michael Miltenberger. During the bidding process, proponents were not required to adopt the original design and could suggest alternative concepts. The only requirement was the existing hospital not be demolished. Successful bidder Boreal Health Partnership proposed a stand-alone facility with the old building used to accommodate complementary commercial ventures. Increasing to 27,000 square metres from the current 13,300, the new hospital will have 100 inpatient beds and expanded emergency, outpatient, and dialysis services to better serve its 47,500 users. It will include a larger medical laboratory, additional space for diagnostic imaging and surgical procedures, along with more exterior parking. It will not however, accommodate out-patient rehabilitation, extended care services or the finance department. A previous design included a 1,281-square foot rehabilitation centre but now it will be housed in a secondary building along with an 18-bed extended care facility expected to be constructed in 2018/19 for long-term respite and palliative care. In January, the GNWT signed a contract with developer Ventura Stanton Inc., to re-purpose the existing hospital as commercial space. Some of the revenues from leasing the space will be shared with the territorial government. The contract includes a $13-million retrofit of the existing structure which will see renovations to the interior and exterior, a new roof, sprinklers, ceilings, lights and conversion of the heating plant. Possible uses for the building include: medical, dental and other health professional offices; general or business offices, restaurants and food services, retail, gyms or sports facilities, education facilities, child care, art galleries and cultural facilities, accommodations for visiting medical workers, residential housing, long term care or assisted living, nursing home or hospice and hotel accommodations. Liquor and tobacco sales, firearms sales, gambling and adult entertainment would be prohibited. Under the public-private partnership (P3) Boreal Health Partnership will shoulder the upfront costs and risks of the project. This is estimated to have saved the GNWT approximately $174.5 million or 25 per cent compared to a traditional procurement. Construction is anticipated to be completed by 2018. The new building will meet the demands of territorial population growth through 2050. fact file Stanton renewal by the numbers Value of construction contract: $300 million Total capital cost: $350 million Value of contract with Boreal Health Partnership: $751 million Estimated cost of traditional design and build: $1.1 billion Savings through public,-private partnership (P3): 25 per cent ($290 million) Construction start date: Fall 2015 Construction completion date: Late 2018 Fully operational: 2021 Number of beds: 100 Total size of new building: 280,000 square feet Source: Department of Health and Social Services Yellowknife hospital history 1937: Cottage hospital and first-aid station built at Con Mine, in which Dr. Oliver Stanton and his wife, Ruth Stanton, delivered the first babies born in the mining community 1942: Sixteen-bed Con Mine Hospital built, which remained the city's primary hospital until 1947 1947: Construction begins on Red Cross Hospital beside Frame Lake near the present location of the Yellowknife RCMP detachment on 49 Avenue 1948: Red Cross Hospital opens on Jan. 6 1960: Red Cross leaves and the hospital is renamed Stanton Regional Hospital 1966: Stanton Regional Hospital burns to the ground on May 22 1966-67: The Elks Hall in downtown Yellowknife becomes an emergency hospital, with the downstairs clubroom serving as an operating room and the upper level used for the ward 1967: Stanton Yellowknife Hospital opens on Franklin Avenue with 37 beds near the present location of Aven Manor 1969: More hospital beds added 1984: Funding for the current $43.6-million hospital is approved 1985: Architect's rendering is approved 1986: Construction begins 1987: Interior work continues and parking lot is established 1988: Current Stanton Territorial Hospital opens Source: Department of Health and Social Services NORTHERN CONSTRUCTION 2016 8 NEWS/NORTH, Monday, April 25, 2016 Canol Trail cleanup begins Local crews working to collect, dismantle 1,600 kilometres of tangled telephone wire by Meagan Leonard Northern News Services Lli Goline/Norman Wells After years of lobbying by Sahtu residents, the federal government has initiated a project to clean up hundreds of kilometres of tangled wire and refuse along the Canol Heritage Trail. Constructed during the Second World War, the 355-kilometre trail weaves its way through the Mackenzie Mountains from Norman Wells to Whitehorse. The trail was originally used as a pipeline by Canadian and American armed forces to transport oil from the Sahtu to refineries in the Yukon. Although it was only in operation from 1943-44, the service road moved some 225,000 tonnes of equipment over the old Athabasca River route from Waterways, Alta., to Fort Fitzgerald near present day Fort Smith. Approximately 30,000 civilians and 1,300 service men helped bring the project to fruition. After it was abandoned, 1,600 kilometres of telephone wire was left behind along with other refuse, including rusting trucks and rotting pumping stations. Today most of the original road has vanished in several places due to landslides and washouts but the trail is still passable on foot, ATV or horseback and attracts serious hikers from across the continent. Now as part of a larger remediation effort to promote the trail as a tourist destination, a large clean-up project has begun. The pipeline is listed on the federal government's list of contaminated sites and small sections have been cleaned up since 2009. The remainder of work will be executed by the Doi T'oh Territorial Park Corporation and is expected to take around four years to complete due to seasonal restrictions and major river crossings impeding travel at certain times of year. Last August, a crew of 13 started work to dismantle, collect and consolidate the telephone wire which over the years has become a hazard to both hikers and wildlife – specifically moose and caribou whose antlers become entangled. Over the years a number of animal carcasses have been recovered after they became trapped and perished. Brush cutting with saws and chainsaws will be required to access wire, including handheld heavy duty wire cutters and ATVs for transportation of crews and wagons. Work is divided into five zones which NNSL file photo Participants in the annual youth Canol Heritage Trail hike reach the 36-mile pump station last July. The federal government is funding remediation of the trail to remove thousands of kilometres of tangled telephone wire left over from its use as a transportation corridor during the Second World War. will be addressed depending on weather conditions and available funding. Crews were divided into three teams, each made up of two cutters and a bear monitor. During the 2015 season, a temporary camp was established along the trail and moved with crews. It included soft-walled tents, a kitchen and personnel quarters and employed a head cook, cook's assistant and general labourer to assist with the collection of firewood, water, mobilization and bear monitoring. Crews work on a two-week rotation and are transported to and from base camp using fixed wing or rotary aircraft. In 2015, work began in Zone 5 near the airstrip at Mile 222 and moving toward the Ekwi River at Mile 180. Some wire removal from Mile 222 to the Yukon border was also started. The second phase saw crews move to the airstrip at Mile 80 and 90 near the Andy Creek Road Maintenance Camp and work toward 131. Phase three will see crews work from Mile 80 to 50. Phase four will begin at Godlin Lake with crews camping at Mile 170 and moving toward Mile 131. Each phase was estimated to take approximately two weeks to complete. According to a project plan submitted to the Mackenzie Valley Land and Water Board, the wire will be "securely stored" until the full trail remediation program can be initiated in the future.

Estimated to be complete later this year, the $84-million project will see 1,154 kilometres of fibre optic cable installed underground from Fort Simpson to Inuvik. Each community along the way will have a "point of presence" established which will give a boost to the transmitted signal and allow for distribution. An extension to Tuktoyaktuk is also planned at a later date. Construction is being managed by Northern Lights General Partnership, a consortium consisting of Ledcor Developments Ltd., including Ledcor Technical Services, of the Ledcor Group and Northwestel, which is owned by BCE Inc. In March 2016, Ledcor announced it was firing and suing its primary subcontractor Rohl Enterprises after continued deficiencies in the cable's installation. Approximately two-thirds of the fibre link was installed by the company. A week later, Rohl counter-sued Ledcor, stating issues with the link's installation resulted from poor plan- ning and a "faulty" design. Ledcor has said it will complete the repairs and remaining work itself while shouldering the cost. Construction has been progressing in three stages: along the all-weather road from the south to Wrigley, the winter road from Wrigley to Fort Good Hope and continuing along the winter road through Fort Good Hope to Inuvik. The winter 2015 construction season saw 220 kilometres of cable installed south of Inuvik, along with line along the winter road between Fort Good Hope and Tulita. Last summer, cable was installed from McGill Lake near Fort Simpson to Wrigley. Crews saw-cut along the winter road and through the forest installing submarine cable up to one metre below the surface along the allweather road and 30 to 60 centimetres along the winter road using a trench method. Once the cable is laid, the trench is immediately backfilled and graded. In areas of permafrost, the cable is placed in the active layer, reducing the potential effects on the permafrost. In the southern portion leading up to Wrigley, cable is laced through a 1.5-inch high density polyethylene tube plowed into unfrozen ground during the summer season beginning in early June. Horizontal drilling was used to run pipe under the Workers tear up the ground in Fort Simpson last July so operators could lay fibre optic cable in the ground. They worked their way along the highway and up the road to Wrigley. Liard, Mackenzie and Great Bear rivers. Throughout the last year, Ledcor has had to complete remediation work along many areas of the cable after discovering cases of erosion, along with trenches and pooling water. In May, inspections by the Department of Lands found 95 per cent of the trench from Campbell Creek, south of Inuvik, to the end of the fibre link, was not covered, with 10 inches exposed in some sections. Cable was also visible at 10 creek crossings with spring run-off causing erosion and silt buildup. In the area between Norman Wells and Fort Good Hope, erosion had loosened cable boxes, creating pools of water which caused boxes to tilt and float following wet conditions over the summer. Remediation efforts have been underway since last year and trenches were back-filled and water diversion beams installed in the Beaufort Delta prior to a September deadline set by the Department of Lands. Industrial, government and scientific organizations have all pledged to purchase portions of the link's bandwidth when it comes online. Northwestel also intends to migrate some of its current services to the fibre link and add new services for local businesses and consumers. It will also be used to expand cell phone service along the route. Former finance minister Michael Miltenberger told the legislative assembly the line would improve community infrastructure, enhance gov- ernment programs and services and "allow more of our residents and businesses to join the 21st century and communicate in real-time with the rest of the world." Currently, Inuvik bounces microwaves along a string of radio towers to Whitehorse. The service is slow and has a low bandwidth, making it less reliable than fibre optic technology. Residents have been left without Internet, debit and credit card services when radio towers are knocked out by storms. NORTHERN CONSTRUCTION 2016 10 NEWS/NORTH, Monday, April 25, 2016 Inuvik to Tuktoyaktuk highway nears completion Final construction season wraps up this month; highway to open in 2018 after two-year wait to let road settle by Meagan Leonard Northern News Services Inuvik/Tuktoyaktuk photo courtesy of the Department of Transportation An excavator works on construction of the Inuvik to Tuktoyaktuk highway in February 2015. The third and final season of construction on the $299-million Inuvik-toTuktoyaktuk highway began in early January with more than 300 employees working around the clock. By 2018, the 145-kilometre highway will connect the two communities in Canada's first road to the Arctic coast. Not only is it the culmination of more than a decade's work by the territorial government, it follows a promise made during confederation nearly 150 years ago – to connect the country from coast to coast to coast. The project is a joint venture between contractor EGT Northwind and Inuvialuitowned companies, E. Gruben Transport of Tuktoyaktuk and Inuvik's Northwind Industries. Currently, there are between 320 and 330 workers on site – 70 per cent of them from the NWT. Employment peaked in March 2015 at around 600 jobs. This season involved hauling and placing 1.4 million cubic metres of material to construct 50 kilometres of embankment. Contractor EGT Northwind also installed four bridges and 19 major culverts with the goal of seeing the north and south construction zones join up toward the end of this month when the construction season ends. Russell Neudorf, deputy minister of transportation, said crews will be working to finish subgrade construction before the early-stage road is left to settle until 2017. During this curing process, a smaller number of workers will shape and pack the highway before covering it in surfacing gravel during the fall of 2017. Around 30 staff will be required over the next year to complete this process, Neudorf said. Construction of the neighbouring Dempster Highway from Dawson City, Yukon, to Inuvik took nearly 20 years to complete and utilized methods more appropriate for southern infrastructure which resulted in extensive permafrost damage in some areas. Neudorf said his department took what it learned from this and applied it to the Inuvik-toTuktoyaktuk highway. "The science around permafrost and the concerns and general knowledge about permafrost has advanced quite a bit since the Dempster was constructed," he said. If done correctly, the permafrost beneath the road should remain frozen yearround – although it requires a little more work as all the fill has to be hauled in, Neudorf explained. As a result of a $669,000 contribution from Transport Canada, two sections of the highway also contain experimental permafrost technology. The south section is testing Continued on page 11 NORTHERN CONSTRUCTION 2016 NEWS/NORTH, Monday, April 25, 2016 11 Workers travel along the Inuvik to Tuktoyaktuk highway during construction in February 2015. photos courtesy of the Department of Transportation Permafrost an expensive problem Ground, soil or rock that has sat at a temperature of 0 C or less for more than two years is called permafrost. It can range from a few metres thick to more than 700. In northern climates, road construction must be completed during the winter before the active layer above the permafrost begins to thaw. As the climate becomes warmer, heat is transferred from the groundwater to the permafrost beneath the highway leading to degradation and ultimate deformation of the highway. The cost to repair and maintain permafrost sections can be between $22,000 to $36,000 per kilometre, per year – approximately 10 times as much as non-permafrost sections. New highway technologies being tested in the NWT and Yukon use different methods of displacing heat to protect the embankment slopes and maintain stability beneath the road. In the winter, cold air can be drawn into the embankment through a culvert, while warm air exits. In the summer, these outlets are blocked. Embankment insulation can also be used to promote air circulation and reduce the effect of solar radiation on exposed slopes. From page 10 the performance of drainage structures with a goal of minimizing the impact of water drainage on embankments by transferring heat and reducing ice. The north section is utilizing a geo-textile reinforced deep fill embankment. This will hopefully add stability to deep fills constructed with ice-rich materials in permafrost terrain. The embankments in these zones are equipped with more than 70 devices to monitor ground temperature, including eight bridge monitors. Data collected from these test sites will be used to inform future highway construction. Although it is still too early to determine full results, Neudorf says since it was installed last year, those sections of the highway have stayed frozen. Completion of the highway will not only open up to motorists the Arctic Ocean, but provide greater access to services and a lower cost of living for those living in the region – Neudorf says he is also expecting it to boost the tourism industry. "Those driving up the Dempster Highway will be able to carry on all the way to Tuk and dip their foot in the Arctic Ocean," he said, adding highway access to the Beaufort Delta will make the area more attractive to investors when the oil and gas markets recover. "These things are cyclical and it will rebound and the highway will be there to accommodate that exploration and development when it returns," he said. Recently the highway has received international acclaim with articles and photo essays in the Toronto Star and New York Times. Neudorf said for many people, the North is still the final frontier and continues to fascinate southern audiences – constructing a highway in total darkness at 40 below through wild terrain seems both romantic and crazy. "It's the fact we're choosing to construct a road to a community that's that far north and the big challenges that come with that construction," he said. "Generally, others are interested in what people are like that choose to live in the North and make this their home." The Inuvik-to-Tuktoyaktuk highway is the first section to be built of the Mackenzie Valley Highway. The next 320-kilometre section from Wrigley to Norman Wells is awaiting funding approval from the federal government and will cost approximately $700 million. It is unclear when construction on that project can begin.

The $35-million project is a joint venture between Clark Builders and the Tulita District Investment Corporation and will see all of Norman Wells' health services amalgamated into one facility, including the medical clinic, home and community care, mental health and addictions services, rehab, medical laboratory and 18 long-term care beds, two of which have been earmarked for transition care. The two-storey, 4,000 square-foot centre is constructed on steel piles using concrete, aluminum, glass and wood. It will employ 88 staff along with 29 new positions. These include cooks and cook's assistants, cleaning and infection control personnel as well as staff to run day programs. Patricia Kyle, CEO for the Sahtu Health and Social Services Authority, said she received her first tour of the construction site this spring. As of March 15, the pilings had been installed, along with the structural steel wall assemblies, floor slabs, vapor barrier, roof membranes and most exterior windows with interior framing started. Originally scheduled for completion in May, that date has been pushed back slightly. "The design builder has shared with us that they're expecting completion of construction in and around November this year," she said. One of the design's unique features is the incorporation of a long-term care facility, located in two adjoining wings containing nine beds each. There will also be two beds reserved for palliative and respite care. A team of personal service workers, cooks and day program staff will be led by a registered nurse. Visiting staff include the community social worker, environment and addictions counsellors and physio and occupational therapists. DESIGNED TO BE HOMEY Kyle said they wanted to make it as homelike as possible in its design. "In each wing or 'house', there's a kitchen, living room and dining room," she said. "So residents with staff can prepare meals together, share meals together and participate in day-to-day activities." She said consultations photo courtesy of the Department of Health and Social Services The new $35-million Sahtu Centre for Health and Social Services and Long Term Care in Norman Wells is anticipated to be finished this spring and is the first of its kind in the territory. were held with an elder representative from each of the Sahtu communities in January on what they would like to see in terms of interior design and decor. Emphasis was placed on incorporating aspects of the landscape and community into the building's design and colour scheme, she said, with the palate and material choices reflective of the natural environment – "warm browns and greens, kind of moss and trees, blues and whites for water, sky, ice and snow." Large windows will ensure ample lighting and views of the land with a number of courtyards and patios also available to residents. There will also be a program area for foot care, hair care, spa, chapel and entertainment or activities. "The elders really spoke to the importance of colour and the design also reflecting nature – bringing the outside, inside," she explained. "They also gave some direction about colours for the health and social services side and really talked about being inspired by themes of healing and hope." The building itself will have aspects of a traditional lodge incorporated into the exterior with a large canopy and community hub in the entryway. Although the facility will primarily serve Sahtu residents, Kyle said she expects there will be applicants for the long term care accommodations from across the territory – it will be determined based on need, not location. "The health and social services centre will continue providing care to residents of Norman Wells and the long term care is one facility for all NWT residents," she said. "Depending on the individual's needs and options available for them it could be residents from anywhere in the territory at this facility." Community infrastructure will also be upgraded to accommodate the new facility, including improvements to sewer and water systems. The possibility of housing units has also been proposed. NORTHERN CONSTRUCTION 2016 NEWS/NORTH, Monday, April 25, 2016 13 Major projects in city's future Bidding opportunities open for roads, water, sewer projects in Yellowknife by Meagan Leonard Northern News Services Somba K'e/Yellowknife Infrastructure investment is high on the City of Yellowknife's priority list for the next 10 years, according to this year's budget. Repairing aging roads and water and sewer systems will be the focus in the near term with larger community projects and facilities receiving more than $100 million over the next five years. 2016 PAVING PROGRAM The city has fallen behind on its road rehabilitation projects and deemed its current level of investment to be "insufficient," stating there is an "immediate need to invest $14.9 million in the existing system" to address roads requiring overlay and reconstruction. This is expected to be covered by a territorial government investment of $34.7 million over 10 years on city capital spending. Approximately $2.8 million has been allocated to the repair and replacement of asphalt, concrete and storm water infrastructure in 2016. New pavement in the city has an approximate lifespan of 20 to 25 years. Projects scheduled for completion this year include repairs to Franklin Avenue from 41 Street to Wiley Road to fix several dips and areas of concern at the bottom of the hill into Old Town. There are also some cited safety issues near Fritz Theil Park where the road has subsided. Reconstruction in this area will include painted bike lanes and stabilization to prevent further degeneration. Paving in Kam Lake will continue between Etthen Drive and Taltheilei Drive in the industrial park. A section of Cameron Road between Nahanni Drive and Taltheilei Drive, originally scheduled to be paved in 2014, will be completed this year. The city made a goal to pave one Kam Lake street per year, with Enterprise Drive, constructed in 2011, the only remaining section. WATER AND SEWER INFRASTRUCTURE REPLACEMENT The City of Yellowknife has identified $3.5 million to replace failing water and sewer underground infrastructure in 2016. Systems installed from the 1940s to the late 1970s utilized pipes made of cast iron and corrugated metal that are un-insulated, resulting in high maintenance and repair costs. The city has since changed its material standards to insulated, ductile iron pipes, which have an approximate lifespan of 50 years depending on permafrost conditions. The program includes: replacing old pipes and water mains with new ones, replacing manholes, hydrants and valves and stabilizing roads with backfill. This work is often done in conjunction with the road paving program. Specific projects scheduled for this year include: Con Road between Rycon Drive and 54 Street and Horton Crescent – which will also be resurfaced with asphalt and concrete. Forrest Drive was excavated and had its water and sewer replaced in 2016; resurfacing is anticipated this year. The city estimated in its 2016 budget that its capital infrastructure expenditures over the next 10 years will total $191 million with $113 million needing to be spent over the next five years. According to documents obtained from the city website, "it is projected that the city will be caught up on major backlogs by 2018." Included in this plan are a number of large-scale pro- NNSL file photo A construction crew works on a re-paving project near the Yellowknife Racquet club in 2014.

Construction of an $8.5 million multi-use outdoor recreation facility on reclaimed land from the Con Mine property is estimated to begin in 2018 with completion in 2021. This is intended to be developed in conjunction with a new subdivision on Taylor Road with land sales used to offset the project cost. A total of $15 million is anticipated to be spent over the next 10 years on municipal facilities including parks and trails. The Ruth Inch Memorial Pool will require replacement or upgrades by 2023. The city is anticipating the design and construction of a new facility starting around 2020 to "meet the growing demand for aquatic leisure." Based on the cost of similar projects in other Northern communities, such as Iqaluit which is currently wrapping up construction on its new aquatic centre, the facility is expected to cost between $30 and $40 million. An expansion of the current pool is also being considered, which would carry a slightly cheaper price tag of $20 to $25 million. By 2017, current operations at the city landfill will be relocated to a new cell at a cost of $3.5 million. Reclamation of the old site will continue until 2025 with another new cell planned for 2022 at a cost of $4 million. A new library has also been forecast but not yet received funding approval. A cost estimate has not been determined but is expected to be offset from the sale of the current space by $2 to $3 million. Another large project will involve replacing the water pipeline running from the Yellowknife River to the water treatment plant. It is expected to reach the end of its life by 2020 with a price tag of $20 million to replace. The city intends to finance this project through external borrowing with construction to begin in 2019.

A 3D model of the CHARS site shows public spaces, laboratories, knowledge-sharing room, interview rooms, kitchen, cafeteria and reception area. Soon to be the largest building ever constructed in Canada's North, the Canadian High Arctic Research Station is well on its way to a 2018 commissioning date. Construction of the $142.4 million facility began in the summer of 2014 and is anticipated to wrap up in time for Canada's 150th birthday in 2017. Once complete it will include research labs, centres for technology, development and knowledge sharing, along with facilities for teaching, training and community engagement. It will house over 19 laboratories and workshops, with office, meeting, conference, dining, logistics and accommodation facilities. Coming in at a massive 50,000 square feet, it will require around 60 staff to maintain, conduct in-house research and deliver programming. As of March 2016, representatives from Indigenous and Northern Affairs Canada said "significant progress had been made" in its construction with the two triplex accommodation units complete and entering care and maintenance. The construction manager and Polar Knowledge Canada staff are expected to take occupancy this month. The exterior of the field and maintenance building is complete and it is scheduled for occupancy in November. The foundation or substructure of the main research building was also finished and structural steel (super structure) erected. It is meant to serve as a hub for both Canadian and international scientists – providing a space for collaboration while improving the information base regulatory approvals and resource development in the Arctic. On a local level, it will assist with the development of community infrastructure, including water and waste water treatment, roads and housing. It will also serve as a marine security outpost for the Northwest Passage with plans identified to improve the effectiveness of underwater observation systems. TRADITIONAL KNOWLEDGE A PRIORITY The incorporation of traditional knowledge has also been identified as a priority with a contract awarded to the Kitikmeot Heritage Society to create a data base where researchers will be able to share knowledge with Inuit communities. Researchers will also be required to demonstrate how their projects will use traditional knowledge with all funded projects to be carried out in partnership with Northerners. Students enrolled in Nunavut Arctic College's environmental technology program in Cambridge Bay will be trained to serve as future research assistants. "Scientists are encouraged to work with community leaders, elders, hunters and other knowledgeable individuals to incorporate traditional knowledge into the design and conduct of the study," says a report from Polar Knowledge Canada, a Continued on page 15 NORTHERN CONSTRUCTION 2016 NEWS/NORTH, Monday, April 25, 2016 15 A sneak peak at CHARS photo courtesy of Indigenous and Northern Affairs Canada An interior view of the knowledge-sharing centre.

"Community input to the research is important, as are sensitive and sound researcher-community relations; all must be clearly demonstrated in project proposals." SCIENCE CAMPS FOR YOUTH Science camps have also started being offered for youth in the summer as a way of encouraging them to pursue careers at the facility after high school. The project is a joint venture between construction managers EllisDon Corporation and Iqaluit-based NCC Dowland Construction Ltd., with design consultants Fournier Gersovitz Moss Drolet and Associated Architects and NFOE and Associates. Both of the design firms have previous experience in Arctic construction and architectural design – including science and research facilities. Construction was separated into smaller projects to make them more accessible to local companies and trades to encourage local jobs and skills development. A $55-million Inuit Benefits Plan submitted by the construction manager will be used for Nunavut Tungavik Incorporated registered firms, training and capacity-building for Inuit. As of March 2015, 26 work packages had been awarded with more than 65 per cent of the value undertaken by Inuit-owned or NTI registered firms. Approximately 150 jobs have been created during construction, with the majority filled by Nunavummiut and other Northerners, complimented by southern specialists. The sustainable design was developed using the Inuit Qaujimajatuqangit (societal values) of respecting the land and environment, providing for family, and working together for a common cause using innovation and resourcefulness. The main research building will serve as the centerpiece of the facility, connecting the main public entrance and a secondary entrance which faces the community. A large public area will feature an atrium and reception space with meeting rooms, casual seating and a cafeteria. The middle of this public space is designed in the shape of a "qalgiq" or igloo which will serve as the knowledge-sharing centre where scientists and residents can share research and traditional wisdom. The facility is expected to achieve Gold certification for the main research building along with the field and maintenance buildings under the Leadership in Energy and Environmental Design (LEED) rating system. It has thus far managed to remain on schedule and budget. The campus is expected to be operational by July 2017 with full commissioning in March 2018. The federal government has committed $46.2 million for the station's science and technology program along with $26.5 million annually for the centre's ongoing operations starting in 2018/19.

Its deteriorating condition and the potential risk it posed to site stabilization workers and infrastructure made its removal a priority. Rehabilitation of Yellowknife's notorious Giant Mine is in full swing as the federal government searches for a construction manager to oversee some $600 million in clean-up related work at the site. A request for proposals will be posted in May, according to officials with Indigenous and Northern Affairs Canada (INAC), with detailed company proposals and financial bids anticipated by the fall. Whoever is chosen will be tasked with the responsibility of posting tenders and delegating work to sub-contractors, including a number of job packages involving drilling, blasting, environmental monitoring, mine work and ongoing care and maintenance. It has yet to be determined when the work will start or how many jobs will be created. The clean-up project, which has been run by INAC since the mine's insolvency in 1999, involves decontamination of the defunct mine which contains some 237,000 tonnes of arsenic trioxide as a result of mining activities which began in the late 1940s. The focus of site remediation up until now has been development of a storage method for the arsenic trioxide created during mining operations as gold was extracted from mined ore. Today, the toxic dust is stored in five underground areas known as "stopes" – large chambers whose walls have been chilled to create a zone known as a "frozen block." This process ensures no water can get in or out of the underground vaults. Another chamber, which is currently empty, could be used to store waste from remediation activities. Results from a freeze optimization study initiated in 2011 determined passive freezing – without using an external power source – could be as effective as active freezing. Both techniques remove heat from the rock, allowing it to freeze; however, passive freezing techniques utilize "thermosyphons" – vertical refrigeration tubes which use gravity to exchange heat. The study also determined the chambers would remain safe at a temperature of -5°C or lower and multiple chambers could be frozen together.

Water board issues a water licence for site stabilization. Work begins on roaster decontamination and deconstruction. Source: Indigenous and Northern Affairs Canada Air quality monitoring program to expand this year Cleanup, from page 16 ing methods were also tested. The wet method involved filling each chamber with water prior to freezing, creating an ice-cube-like block while the dry method freezes the rock around each stope or chamber. The dry method was preferred because it is easier to reverse or remove the arsenic if new technologies arise. "The study showed that there is no significant advantage to the wet method," the report stated. "Both methods work to keep water and arsenic trioxide from passing into, or out of, the stopes and chambers." Changes to the air quality monitoring program can be expected this year. Previous monitoring focused on three specific zones: the main Giant Mine site, along site perimeters and at three community sites, including Ndilo, downtown Yellowknife and at the Great Slave Sailing Club near the mine site. After dust clouds from tailings ponds made their way across Back Bay to Ndilo in May 2015, additional measures have been put in place to prevent this during the spring thaw. Several measures were implemented this winter, including storing larger amounts of dust control product, daily wind forecasting, 24-hour dust monitoring, and additional water trucks being sent to wet dry areas. Surface design engagement has been ongoing since early 2015 as remediation teams meet with interested parties to brainstorm ideas for site development. Topics of discussion include Baker Creek, pits, soils and tailing ponds – specifically the future location of Baker Creek, tailings vegetation and contouring, stabilization of open pits and what restrictions arsenic levels may pose to future uses. The project team is currently in the process of analyzing these options and their potential impacts before incorporating them into the final surface remediation plan. Activities to reduce the risk posed by aging infrastructure were also undertaken at the site last year, including stabilization of eight underground stopes, deconstruction of the C-Shaft headframe, installation of buttresses at the C1 Pit to prevent water from Baker Creek entering the mine and continuation of roaster complex cleanup. Stope stabilization involves filling the empty spaces with a paste comprised of tailings, water and cement which prevents rock collapse and underground flood- ing. By October of last year, all of the empty stopes had been filled with 60,000 cubic metres of paste – "enough to fill Yellowknife's Ruth Inch Memorial Pool 100 times." The iconic C-Shaft headframe was constructed in 1949 and was a part of the skyline for more than 60 years. Deconstruction involved the dismantling of five structures, the screen house, conveyor galleries, crusher house, trestles and headframe. The narrow, vertical hole reaching 650 metres underground still remains and a cap was installed over the shaft in November. Currently, water from the site is treated by a filtration plant constructed in the 1980s and several improvements have been made to that system. A new water treatment plant is in the works. Other highlights from last year include the establishment of a Giant Mine oversight body in October. The group, comprised of six community representatives, will be responsible for providing public awareness and independent advice to the federal and territorial governments and regulatory authorities while also managing a research program for the development of a permanent solution for the Giant Mine site. NORTHERN CONSTRUCTION 2016 18 NEWS/NORTH, Monday, April 25, 2016 Aquatic centre a feat of ingenuity State-of-the-art facility expected to be complete by the end of this year by Meagan Leonard Northern News Services Iqaluit NNSL file photo Construction crews scrambled to finish 2015 season work on the Aquatic Centre last fall after summer sealift delays set the project back by three weeks. Iqaluit's 11-year dream of having a state-of-the-art aquatic centre is finally becoming a reality. The $40-million project was delayed three-weeks last fall after heavy ice in Frobisher Bay slowed down sealift delivery resulting in crews working overtime past the Nov. 6 season deadline for construction. Despite this setback the project is still within budget and on pace for a 2017 opening. With the structure of the building complete and weather-tight, construction crews have returned to continue with interior work. City of Iqaluit recreation director Amy Elgersma said they were filling up the pools with water during the first week of March to test the concrete and she expects the remaining work to be finished by December. "There have been some small challenges here and there but basically everything has been going really, really well," she said. Previously, the city leased pool space from the Frobisher Inn and a small fitness centre in a separate facility, which was staffed by volunteers from 5:30 to 10:30 p.m. Both services will now be under one roof at the new aquatic centre. Elgersma said the city saw demand for a larger facility with extended hours to accommodate different schedules. The new aquatic centre will feature lap and leisure pools, spray technology, a water slide, one-metre spring board, Tarzan rope, sauna and whirlpool. The city has partnered with the local non-profit fitness centre to incorporate a fitness room and studio and there will be a food and beverage area. An elder's space will allow residents to hold meetings or relax with family while a multi-purpose room will be available for training sessions or private rentals such as birthday parties. Elgersma said the elder's room in particular was an important aspect they wanted to include. "We wanted to include them in the facility and make sure they had a space of their own," she explained. BUILT OFF THE GROUND The facility is also a remarkable feat of engineering and one of the first of its kind in the North, Elgersma said. Designed by Stantec architecture in collaboration with a pool specialist from B.C., the centre is elevated one metre off the ground. Piles are buried 30 feet in the ground and grouted to the bedrock, which allows the 3,500 square foot facility to be suspended, maintaining cold air circulation without inhibiting the permafrost. This was particularly difficult due to the combination of the high internal temperatures and humidity in a dry Arctic climate. "We wanted to make sure with the possibility of climate change, the pool wouldn't be affected," said Elgersma, adding the city travelled to other Northern areas such as Nuuk, Greenland for ideas, but ultimately, still had to develop an innovative approach to its design. "Iqaluit was unique. A lot of the other communities didn't have the same permafrost issues that Iqaluit has … we'll be able to share some of that going forward with other Northern communities." She said the city is also hoping to achieve LEED silver status for energy efficiency. LEED Canada rates new buildings for their performance in water saving, energy efficiency, material selection and indoor environmental quality. Elgersma said the centre will have low-flow toilets and utilize "waste heat" from the neighbouring power plant. "They have big generators, there are a couple of other buildings that are on the system as well as nearby, so we'll tie into that and we'll be able to use the waste heat from the power plant to heat about 80 per cent of the building," she said. The city just received word it had been approved for $4 million through the Building Canada fund, which Elgersma said will be applied to Phase 3 of the project. The centre also received $8.25 million from the Federation of Canadian Municipalities' municipal green fund, including a loan of $7.5 million and a grant of $750,000. In October, the city issued $80,900 in change orders to contractor Kuglik Construction Ltd., to cover higher insurance requirements, missing pool components, steel orders and credit to the city for a change in the pool's pump manufacturer. Annual operating and maintenance costs of the aquatic centre are anticipated to be around $2 million.
