Soft Story Seismic Retrofit

West Coast Premier Construction has established itself as a leading design-build contractor in providing screening, engineering and construction services for seismic retrofit of soft story apartment buildings. WCPC is currently providing soft story seismic retrofit plans and construction on several multi story apartment and condominium buildings located throughout the Bay Area cities including San Francisco, Alameda, Oakland and Berkeley. These seismic safety improvements are intended to comply with the City’s recently adopted soft story seismic ordinance. Soft, weak or open-front wall buildings, referred to as “Soft story buildings” are seismically vulnerable wood framed multi-unit multi-story apartments or condominiums which have tuck-under garage parking provisions and openings at the first (ground) level walls.

Our company has completed soft-story earthquake retrofit engineering and construction for numerous apartment buildings and condominium projects in San Francisco, Berkeley, Oakland and Alameda. Cost effective soft story seismic retrofit engineering and construction strengthening measures are implemented by WCPC which significantly improve the earthquake resistance of the buildings without a loss of use of the parking space or the compromise of the building aesthetics. After the retrofit, the property is removed from the city’s inventory list of soft story hazardous buildings. Please refer to the Projects Completed section of our website for a partial list of recent soft-story seismic retrofit projects completed to date. Our company provides soft story screening and evaluation, soft story seismic retrofit engineering design or soft story engineering and construction (design/build). We also provide construction for retrofit design provided by other engineering companies. Contact us if your looking for soft story retrofit Engineer; soft story retrofit costs; soft story retrofit construction.

In San Francisco, we are currently providing evaluation, engineering and construction for soft story apartment and condominium buildings in accordance to the Ordinance # 66-13 and the San Francisco Building Code Chapter 34B. These are critically vulnerable buildings with 5 dwelling units or more, 3 story or more, built before 1978, Type-V wood framed construction with wall lines, or structural conditions characterized by soft, weak or open-front (SWOF) walls and a “Target Story” extending above grade whose wall configuration is substantially different from the wall configuartion of the story above. We complete the screening forms and submit the screening forms to San Francisco Department of Building Inspection (DBI) before the deadline for:

  • Tier I Buildings; Group A, E, R2.1, R3.1 or R-4 Occupancy on any story.
  • Tier II Buildings; 15 or more dwelling units.
  • Tier III Buildings; Not falling within definition of another tier.
  • Tier IV Buildings. That contain a Group B or M occupancy on first story and that are in mapped liquefaction zone, except for Tier I buildings.

See our Projects Completed in San Francicso for Soft Story Buildings completed there.

Symposiums on Seismic Soft-Story Engineering and Construction – Our company Principal, Dr. Homy Sikaroudi is regularly invited as speaker in seismic retrofit symposiums and real estate trade expos.
