Steel plays a significant role in the Renewal and New Construction of Terrace Sportsplex and Vanderhoof Aquatic Centre

Steel design has played a vital role in structures intended to revitalize their communities. The architects designed practical solutions to twinning the existing arena as the first step in the Terrace Sportsplex Project Revitalization. A pre-engineered steel building by Behlen Industries was used for the second arena, which provides an important training ice surface for hockey-crazy Terrace.

Through careful budget planning, interior improvements were made to the existing arena and Sportsplex. These improvements focused on improving spatial flow, both in the first and second floor entrance ways and in some exterior improvements, including replacing wood cladding. The project is strongly characterized by a cantilevered multipurpose space, designed to take advantage of Terrace’s impressive mountain views. The second floor addition provides a canopy over the entrance, much needed community-use space, as well as warm, second floor viewing areas for both ice sheets.

Subsequently, Carscadden Stokes McDonald worked with the City of Terrace to complete a full review and assessment of the Aquatic Centre located in the same campus of facilities as the Sportsplex. In regard to the Vanderhoof Aquatic Centre, a whole new facility was built, replacing the old aquatic facility.

“Pre-painted steel is an elegant material to work with. It is durable, low maintenance, colourfast and it comes in a number of profiles we like, plus it’s a delight to work with.” said Ian McDonald, partner architect.

Armen Mamourian, principal architect with Carscadden Stokes McDonald Architects Inc., explains the revitalization at the Sportsplex, “the community of Terrace had hoped to twin their existing ice sheet at the Sportsplex to meet growing demand”. Armen continues, “earlier attempts were coming in over budget, so this new design exploited steel structures in general and stressed skin-steel buildings in particular, to meet the demands for long spans, durable surfaces, and simple foundations,” he says.

A Convex frameless steel building system, by Behlen Industries was used in the Terrace Sportsplex Revitalization for the second ice surface. This steel building system (SBS) approach was chosen for its ease of constructability, spread footings and serviceable interiors. Additionally, the frameless approach provided clean and clear interiors with natural ceilings. The stressed-skin steel building addition mimicked the form of the existing roof, while providing a practical, modern solution. The exterior cladding of the second arena is clad with AZM180 Galvalume coated steel.

Meanwhile, in Vanderhoof, building a local aquatic facility had been a community aspiration for years. The district undertook extensive public consultation and a successful referendum to determine the type of facility which would add value to the local area as well as gaining access to the funds required to bring the project to reality.

“Again, while there was a strong desire to showcase wood elements, as the forestry industry is a big local presence, the budgetary considerations and large spaces unimpeded by structural elements led us to an elegant steel framed build- ing solution,” says Mamourian. “The construction of the new aquatic facility is intended to promote public health and year-round activity for the town’s residents. It is located next to the existing ice arena in the centre of town to create a convenient and accessible athletics precinct.” While a pre- engineered steel building was used for the Terrace Sportsplex revitalization, steel framing and steel roof deck along with steel roof cladding was used for the Vanderhoof Aquatic Centre. Wood has been used in the building’s interi- or finishes in a nod to the local forestry industry.

The structural steel roof of the Vanderhoof Aquatic Centre is a striking focal point, McDonald says. “I think it’s quite shapely. The design was meant to evoke the landform of the surrounding topography. The crinkled and folded roof is pretty dramatic.”

The Sportsplex revitalization was completed in December 2018 and the Vanderhoof Aquatic Centre in January 2019.

Saskatoon Civic Operations Centre Steel Provides Energy Efficient Envelope

The impressive Saskatoon Civic Operations Centre is a LEED certified facility that serves as the home of Saskatoon Transit and the city’s first snow management location. The transit facility is 41,805m2 (450,000 sq. ft.) and has indoor storage for 224 buses. The snow management facility is situated on a 5.67 hectares (14 acre) concrete pad with the capacity to store up to 1,000,000m3 (35 million cubic feet) of snow.

“The City of Saskatoon wanted an innovative program on a site that they had attained,” said Gerry Garvin the Senior Contract Administrator in an interview with Steel Design magazine. “It is bounded on one side by the CN rail line and railyards, so it’s a fairly linear site and bus movement is paramount in moving […]

Nerves of Steel in Inuvik, NWT: Galvalume™ Steel and Light Steel Framing provide Flexibility, Durability and Design Freedom in the North

There are many reasons why using steel products are beneficial to architects and builders everywhere, but one of the most useful reasons for steel in everyday design is because of its ability to handle extreme weather. The far North has a harsh climate, this includes bone-chilling cold temperatures that are not uncommon in places like the Northwest Territories and the sun and wind are very hard on materials.

Steel has a lot of flexibility, which provides plenty of design freedom. It’s a robust material, light-weight, durable, attractive and maintenance free. Buildings in northern, remote locations are a particular challenge, therefore the use of durable, prefinished and corrosion resistant steel is important, which is why steel was the choice when it came time to […]

The Centre Sportif Marc-Simoneau is evocative of glaciers and ice

Pre-painted Z275 (G90) galvanized steel assists in ensuring perfect architectural integration. When the snow is piled up against its white, multi-faceted exterior, the Marc-Simoneau sports complex looks like an ice crystal, a chunk of glacier imbedded in the ground. The morphology of the main entrance results from an idea referring to the physical phenomena of glaciation and crystallization of water.

The volumetry of this complex suggests a jagged-shaped glacier, a fragmented snow block reflecting sunlight, a piece of frosted and translucent ice in the northern environment,” says Yan Laplante, associate architect with CCM2 Architects. The whole structure is extremely light, even considering the load consisting of the snow in winter, which is considerable in the […]

Steligence®: The Intelligent Construction Choice

Steel has long been integrated into building construction and recognized as a significant material in traditional and modern building design. Steligence® is a research initiative delivering a range of fact based sustainability and cost benefits to architects, engineers, urban planners, real estate developers and construction contractors. Each benefit is individually attractive; together, they create a compelling argument for the use of steel products in construction.

In the case study presented here, a mid-rise office building in the GTA area was virtually designed using steel component construction and contrasted against concrete construction. The functionality of the building did not change; identical use, occupants, size, geographic location were critical in ensuring a responsible comparison. Life Cycle Assessments of the design scenarios were […]
