How the work runs
Foundation Design & Repair
Bay Area soils range from expansive clays to steep hillside fill, and each demands a foundation engineered for its site. We design deep pier and grade-beam systems, mat and spread footings, and retrofit failing foundations with solutions that carry load to competent bearing soil, documented with stamped calculations your building department will approve.
Seismic Retrofit for Homes
Living in earthquake country means your home should be anchored to resist lateral forces. Our seismic retrofits (foundation bolting, cripple-wall bracing, and soft-story reinforcement) protect your family and your equity while satisfying local retrofit ordinances across Oakland, Berkeley, and San Francisco.
ADUs, Additions & Wall Removals
Opening up a floor plan or adding square footage changes how load travels through your home. We size beams and posts, design new load paths, and detail the connections so contractors can build with confidence and inspectors can sign off without delay.
Questions we hear
Do I need a structural engineer to remove a load-bearing wall?
Yes. Removing a load-bearing wall requires a stamped structural design showing the replacement beam, posts, and foundation support. We provide permit-ready plans and calculations that your city will accept.
How much does a residential structural inspection cost?
Cost depends on the size and scope of the property, but we provide a clear, free quote up front. Call (341) 221-1747 to discuss your project and get a fixed price.
Do you help with ADU structural plans?
Absolutely. We prepare the structural plans and calculations required for ADU permits throughout the Bay Area, coordinating with your architect or designer.
