Washington State Legislative Building Project Profile

The rehabilitation project at the Washington State capitol began not only as a reaction to an earthquake in 2001, but also as a charge to modernize a truly historic building. Crews were required to incorporate contemporary materials with the longevity to preserve the building's features while keeping the historical perspective of the building true to the original construction — right down to the way building materials, like plaster, were worked when the building was constructed in 1922.

For such a detailed and highly specific rehabilitation under a tight deadline, construction crews incorporated Red Top® Gypsum Plaster, Red Top® Keenes Cement/Ivory Lime and USG Accelerators to repair fixtures and patch cracks that, in some places, were required to match as many as 100 grades of sand.

Crews worked around the clock to apply more than 100,000 sq. ft. of plaster and at least 7,000 lineal feet of decorative plaster ornamentation to major structural and feature areas of the building, including the Capitol dome and main legislative chambers, completing the project two months ahead of the scheduled return of the building's occupants.
