Seattle, Washington

Escala, a 31-story luxury high-rise residential tower in downtown Seattle was born of a world class vision. The building was to have expansive floor plans with minimal structural obstructions, which inspired the enginners to innovate.

CKC designed an innovative dual system of shear walls and frames, using ultra high strength concrete and 100 ksi rebar for seismic resistance.

Escala was the first structure in North America, and perhaps the world, to use 100-ksi steel for seismic reinforcing. It proved an excellent solution to the congestion that would have otherwise occurred with conventional grade 60 rebar.

This successful marriage between structure and architecture placed Escala among the premier buildings in North America, and began a new era in the construction of tall concrete buildings in seismic regions.
