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)
– Conversion of eight units to meet Type A accessibility.
