This project is a substantial renovation and seismic retrofit of Seattle’s first concrete high-rise apartment building, a historic 1923, 10 story apartment building next to I5 in downtown Seattle. The building has 157 units of affordable housing and was partially occupied throughout construction.
Initially a plumbing retrofit project, during preconstruction our team worked with Bellwether to incorporate additional scope. As more funding was acquired, we updated the budget and incorporated a scope of work that maximized the value of the amount of funding raised while also meeting jurisdictional code requirements for high-rise buildings.
Our final scope of work for the project included:
- new plumbing systems
- installation of 6 concrete footings and shear walls from existing foundation footings to 9th floor for seismic (including significant excavation inside the building for the new shear wall footings)
- two full elevator modernizations
- new emergency generator installation
- replacement and reconfiguration of electrical, fire alarm and low voltage cabling in corridors
- new ERV system for common areas
- new stairway and elevator pressurization
- fire alarm system replacement
- new fire sprinkler system
- new DAS system
- complete low voltage replacement
- new water service to building (required by new fire sprinkler system)
- new cabinets, countertops, appliances, and plumbing fixtures in units
- new common area flooring and complete interior repaint
- lobby restoration included demolition of existing offices to restore lobby to original condition (polish terrazzo floors and storefront glazing for offices show restored historic features inside)
- new windows (that meet National Park Service historic requirements)
- and conversion of eight units to meet Type A accessibility.
