Vertical Transportation
Size
1.2 million sf – Washington Mutual
335,00 sf – Seattle Art Museum
The Washington Mutual Corporate Tower is a 608 foot tall
building with 42 levels above grade that provide access to 1.2
million sf of office space as well as seven levels of below grade
parking. Updated standards of ‘Ride Quality’ led them
to partner with Syska Hennessy Group’s Vertical Transportation
Division for the design specification of twenty-five traction elevators
providing service at 1400 fpm. The high-rise elevators were specified
to have a ride quality of no more than 12 mg’s, with noise
levels not to exceed 50dBA, which exceeded all other systems installed
at that time in the Pacific Northwest.
In conjunction with the Washington Mutual project, Syska partnered
with the adjacent Seattle Art Museum on their renovation project
and pioneered the concept of the ‘Machine Room-Less’ type
elevator system. The design for these types of systems provides
the client with the most efficient building designs available
while providing the most energy efficient elevator equipment
obtainable. At the completion of the project, Syska engineers
provided the design for eight traction elevators, one hydraulic
elevator, and six new escalators that would service a 335,000
sf space consisting of twelve levels of public assembly space.
