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
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, subcontract-
ed the roof to steel structural engineering spe-
cialists, Walter P Moore
Supply, fabrication and installation of all
structural steel. Walters also took on a de-
sign-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
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
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
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 un-
der way and nearly complete in
some areas. Inside, crews are work-
ing on mechanical and electrical
systems; walls are framed out, and
painting is in progress.
Installation of the specta-
tor roof material will be-
gan 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
• 45,000 m³ of cast-in-place concrete has been
• 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.
