Crews took only six months to complete this Boeing plant building, despite design changes during construction.
Boeing 45-335 temporary manufacturing facility
General contractor: Washington Patriot Construction
Owner/developer: The Boeing Co.
Primary designer: Coffman Engineers
The Boeing 45-335 project involved construction of a pre-manufactured metal building over an existing concrete slab to provide a facility for working on unfueled aircraft at Boeing’s Everett plant. The project also included two modular support buildings to house additional workspace and restroom facilities.
A substantial amount of scope was added during the construction phase, including an upgrade to the Very Early Smoke Detention Apparatus (VESDA) system in the plane stalls. Steel requirements were changed for structural wind loads and, being unable to tie into existing air systems, compressor scope was added. Additionally, water was not available near the building and had to be pulled in from elsewhere, and a metering system was added to all major utilities going into the building.
All this work was on an existing concrete slab, so this additional work and scope required Washington Patriot crews to demolish and replace all the concrete that had been disturbed.
