Steel Fabrications for Mosaic Stadium
Under construction, with work now advanced on installing the steel roofing complex, the Mosaic Stadium will be the new home of the Saskatchewan Roughriders professional football team.
The stadium, designed by HKS, is being built for the City of Regina. It includes a very complex roof steel geometry with very few 90° angles and extremely complex connection nodes. The main contractor, PCL Construction, subcontracted the roof to steel structural engineering specialists, Walter P Moore
Supply, fabrication and installation of all structural steel. Walters also took on a design-assist role to ensure the workability of the stadium’s complex geometry of structure. The complex roof requires over 3,200 tons of steel.
The curvilinear shape of the cantilever roof required unusually high tolerances and intricate joint construction.
These joints (or nodes) are where all forces convene on a central point. Prior to work commencing, Walters created models to simulate stress tests, based on the exacting work of their team of experienced engineers, who created the calculations that inform the models.
The secondary steel layer that covers the primary roof structure had to be coordinated with a translucent fabric covering.
This required working with the fabric contractor in painstaking detail over six months to ensure that their fabric design and the steel design came together harmoniously.

Main Contractor On Schedule
The new Mosaic Stadium, due for substantial completion in August, 2016, has seen steady progress in the past months—both inside and out and is 77% complete.
The outside finishes are well under way and nearly complete in some areas. Inside, crews are working on mechanical and electrical systems; walls are framed out, and painting is in progress. Installation of the spectator roof material will began this spring.
There has been tremendous activity on all areas of the site, with crews ranging from 400 to 500 on-site during the last six months.
Construction highlights include the following:
- Just under 300,000 m³ of material has been excavated.
- 45,000 m³ of cast-in-place concrete has been completed.
- 1,200,000 hours have been worked on-site to date.
The stadium will measure 56 m from the field of play to the roof.
The final portion of the field-of-play excavation is taking place to ready it for the eventual installation of the drainage system and the field of play.
