419 Occidental (the former FX McRory’s building) is one of three early 20th-century buildings being updated as part of a redevelopment project that includes an alley activation and new retail district in the historic Pioneer Square neighborhood of Seattle.
This 89,000 SF, 7-story unreinforced masonry, building was built in 1906. The new owners’ plans constitute a substantial alteration of the building’s use. Per the city of Seattle, this change triggers the need to include a seismic renovation along with the other planned improvements.
SSF provided a seismic assessment of the building using the ASCE 41-13 standard building code guidelines. Working with developer Urban Villages and SHED Architects, the seismic upgrade includes a new global lateral resisting system and the anchorage of floor and roof diaphragms to the wall systems. We also designed a Cross Laminated Timber (CLT) structure for a penthouse addition and a new exterior stair, and other structural repairs and modifications beyond the seismic modifications.
The project consists of first floor retail with offices on the upper levels. Construction is underway with Chinn Construction.
