 Mandatory Soft Story Seismic RetrofitSoft Story

West Coast Premier Construction has established itself as a leading design-build contractor in providing evaluation, engineering and construction services for seismic retrofit of soft story apartment and condominium buildings. We have engineered and retrofitted several hundred soft story buildings (signed off by the City). WCPC is currently providing soft story seismic retrofit evaluation, engineering design,  plans and construction on numerous multi story apartment and condominium buildings located throughout the Bay Area cities including Oakland, San FranciscoBerkeley, Hayward, Mill Valley, Albany, Mountain View, San Jose and Alameda. These seismic safety improvements are intended to comply with the City’s recently adopted mandatory soft story 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.

Unreinforced Masonry Seismic Retrofit

Our company has extensive experience in seismic retrofit engineering and construction of unreinforced brick masonry buildings. WCPC completed the earthquake retrofit for First Church of Christ, Scientist located at 1700 Franklin Street, San Francisco. This unreinforced brick masonry historic landmark building accommodates a church auditorium with historic organ pipes, a balcony and a Sunday school that totals over 22,000 square feet in 3 levels.

Several strengthening corrective measures have been incorporated (Five new shotcrete shear walls, three steel moment resisting frames, new plywood roof diaphragm, bracing of tall brick walls with structural steel members as well as attachment of brick masonry walls to roof and floors). In addition new handicap accessible ramps were installed at the main entry and at the sunday school and new handicap accessible restrooms were constructed at each level. The interior of the building received complete new painting and carpeting. All exterior wood framed windows were completely repaired, restored and repainted.

This project was engineered by Sikaroudi & Associates, Inc. and managed by Architectural Resources Group, Inc. While retrofitting the building to the stringent “General Procedure” requirements of the San Francisco Ordinance for unreinforced brick masonry buildings, the design and construction goals were to preserve the interior and exterior historic features of the building. The church and Sunday school services remained operational throughout the construction work. The construction started in April 2008 and was completed in June 2009 and signed-off by the San Francisco Department of Building Inspection.

Soft Story Seismic Retrofit

West Coast Premier Construction has established itself as a leading design-build contractor in providing evaluation, engineering and construction services for seismic retrofit of soft story apartment buildings. We have retrofitted over 250 soft story buildings (construction completed and signed off by the City). 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 Oakland, San Francisco, Berkeley and Alameda. 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.

Contact our company if you wish to comply with Mandatory Soft Story Program, or need assistance with retrofit of your building. Cost effective soft story seismic retrofit engineering design 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; competitive soft story retrofit costs; soft story retrofit construction. Please contact our company (510) 271-0950, for further information.

In Oakland, Soft Story Seismic Ordinance #13516 was adopted into Law in January 2019. Multi-unit wood framed buildings permitted before 1991, five units or more, two stories or more with a “Target Story”  must meet the retrofit requirements of the Ordinance within a six-year program. The program groups potential soft story buildings into three compliance Tiers: Tier, I, II and III.  We can provide full engineering design, City permit submittals and full construction for cost effective seismic retrofit of these buildings. 

In San Francisco, we are currently providing structural evaluation, engineering design and complete construction for mandatory soft story apartment and condominium buildings in accordance to the Ordinance # 66-13 and the San Francisco Exciting Building Code Chapter 4D. 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 configuration 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.

Dear Homy,
It has been such a pleasure to work with you and your crow on this project. I chose your company because everything was done “in-house”. Your attention to detail and patience explaining the entire process; engineering plan, permits, time line for work to be done and budget was so reassuring. I personally thought the whole building might fall down! However the project went without a delay or hitch, on time and on budget.   » more…

…We received numerous bids of which WPC’s was the lowest by more than 50%. The construction work passed all inspections, was completed ahead of schedule and under budget. The budget and timeline savings allowed us to complete substantial unplanned additional work to the facility. WPC was able to handle the additional work either with their own highly skilled employees or their network of quality subcontractors. WPC worked well with our Project Manager, Architect, Engineer, Tenants and various City Departments. Most importantly WPC met its budget estimates and completed projects ahead of schedule…
…Walden House highly recommends West Coast Premier Construction for any seismic and/or non-seismic related work.   » more…

… WCPC is one of the best contractors we have ever worked with. They are on time, on budget, conscientious, and understand and respect the client’s needs and goals. WCPC is consistently able to be very detail oriented while never losing sight of the big picture.
… WCPC produce high quality work at a fair price, and often devise cost-saving, efficient solutions to field problems.
… I wholeheartedly and without reservation recommend WCPC and Sikaroudi, for high quality, timely, cost-effective work. » more…

…West Coast Premier Construction has been our General Contractor on several seismic retrofit, tenant improvements and restoration of masonry building projects, some of which are of architectural and historic value.
…WCPC personnel work well with architects, engineers, construction managers, city inspectors, clients and tenants of the building projects they work on. They have gone out of their way as to even working graveyard shifts to minimize disturbance to the tenants and customers when buildings are occupied.
… I highly recommend West Coast Premier Construction as a quality firm providing cost effective and creative construction solutions especially in the field of seismic retrofits. » more…

… They could not have done a better job as they were competitively price wise, did an outstanding job interfacing with the San Francisco Building Department. Homy Sikaroudi was delightful to work with.
