Construction of West 8th involved one of the largest mat pours in Seattle history. The 5,800-cubic-yard pour peaked at 690 cubic yards per hour.

Lease Crutcher Lewis completed West 8th, a 28-story tower with of 520,000 square feet of office space, in downtown Seattle last year.

The project originally sought a silver LEED certification, but Lewis helped identify and achieve nine new credits. West 8th became the first office tower in Seattle to earn LEED for core and shell gold pre-certification, and it ultimately achieved certification as LEED gold.

With its lean-building approach, Lewis achieved rapid cycle times on the self-performed construction of the core and the placing of the curtain wall, saving time and money. The lean approach also contributed to the project’s excellent safety record: zero accidents and zero time-loss for the entire job.

Using building-information modeling, the Lewis team eliminated almost half of the structure’s projected weight of steel.

The project involved one of the largest mat pours in Seattle history. The 5,800-cubic-yard pour peaked at 690 cubic yards per hour.

Lewis and its client, Touchstone, nominated the project for NAIOP of Washington’s “Office Development of the Year,” which it won.
