Canadian Football Stadium - The Investors Group Field is composed of 9000 tons of steel, 28,000 cubic meters of concrete, 3500 sections of hollow main floor, 450 pieces of precast bleachers, 272,000 blocks, 8 acres of room, 33,500 seats expandable to 40,000 for major events, including Grey Cup and other major international events and concerts. The stadium arch trusses supporting the 8 acres of roof are the largest and highest in Canada, spanning 620 feet and approximately 200 feet in the air. They weigh 950 tons each. All steel pieces were detailed in Tekla Structure with great efficacity.
At the end of the project, we ended up with 8,600 shop drawings, 5000 for the bowl and 3600 for the roof. Some truss connections were so complicated that it was not possible to draw them on paper. The engineering firm, Walter P Moore, used our model to make the connection concept and transferred us the Tekla information so we could complete the 3D. The camber of the trusses was also a big challenge but good communication between our team and the project engineer enabled us to input everything into the model, therefore preventing problems in the field. We inputed in our Tekla model all the cast-in-place concrete and precast that could affect our steel for coordination. We have also shared the model with Walter P Moore to input the deck in Tekla to prevent any misfit inthe field.
Category 3 Winner - Concrete – KGS Group
Manitoba Hydro Spillway Replacement, Manitoba, Canada
Power Generating Station Flow Control Structure - The Manitoba Hydro Spillway Replacement project is an innovative spillway replacement project currently under way. This project involved major earthworks and cast in place components including 30,000 m3 of concrete and 145 tonnes of reinforcing steel.
The estimated total cost of this project is $300 million. This is a pilot project for Manitoba Hydro to fully explore the use of BIM for large scale Hydro projects. KGS Group selected Tekla as the optimum tool to perform the cast-in-place modeling and deliver the construction drawings. This was KGS Groups first cast-in-place project design & detailed using Tekla Structures for reinforced concrete. The coordination of this project fully utilized Tekla IFC, DWG and BIMsight exports to coordinate with the client and other sub contractors.
Many inp and db files were customized to meet the Canadian Rebar standards, industry specific profiles were created as well as creating a full metric cast-in-place environment. Custom templates were created to associate the Canadian Standard Bend Types with the Tekla Structures internal shapes. The rebar/concrete model, drawings, and schedules were completed by 3 Tekla users, with this being the first project for 2 of the users, while the structural steel was detailed by KGS Groups experienced steel detailing department that consists of 7 users.
Barton Malow gained special recognition for exemplary BIM collaboration in John and Mary Brock Football facility, a climate controlled, closed practice facility for Georgia Tech's championship football team. Also, JPW Structural Contracting's Spire Truss at Sutter Medical Center in Castro Valley, California, received an honorable mention for the steel category. The honorable mention in the Concrete Category was given to Ambassador Steel for their model of University Of Alabama Science And Engineering Building in Tuscaloosa, Alabama.
