Location: Seattle, Washington
Award: Lower Carbon Concrete
Project Team
Owner: Force 10 Sports Management
Contractor: Sellen Construction
Structural Engineer: Holmes US
Architects: ZGF Architects LLP and Shive-Hattery
Concrete: Stoneway Concrete
Slag Cement: Holcim

This project in Seattle, WA, USA, presented the construction team with many technical challenges, including the need to minimize the GWP as well as achieve LEED® Gold certification. Sellen Construction had placed concrete with a cement comprising 80% slag cement on a previous project and was aware that it produced a very light color after curing. The contractor therefore worked with Stoneway Concrete to use slag cement to produce the tilt-up wall panels for this project. In addition to maximizing slag cement content and using ASTM C595/C595M Type IL cement for various applications on the job, the design and construction team worked collaboratively to identify areas, like foundations and tilt-up walls, where concrete could be specified with 56-day design, rather than 28 days, further reducing the required amount of cementitious materials to achieve required strength.
