Consult & Design

Our goal is optimized design with reduced construction cost. Very often minor adjustments in the architectural design during the preliminary phases lead to a simplified structural frame and therefore a cost-effective design.  As well, we have the expertise to assess the practicality of any design, taking into consideration both structural feasibility and City Code allowances.

Permit Processing

While the design of any structural system is vitally important, obtaining approval by the deciding authorities is equally so. Navigating permit processing through all departments is a key factor to guaranteeing a timely and smooth project. With over 15 years of experience in processing permit applications through the San Francisco Bay Area City departments, we offer fast and reliable application processing to all our clients.

With decades of combined experience in the construction industry, we provide start-to-finish services for structural and seismic upgrades for residential and commercial buildings, including Soft Story retrofits. Combined Engineering and Construction expertise allow us to complete over 95% of our projects with no change orders during construction.  Throughout the process you’ll be updated with detailed multimedia progress reports.  



Having completed over 140 seismic upgrades in the Bay Area, we’re here to make the process seamless -- from Design to Permitting to Construction.  After a worry-free experience, you’ll be left with the reassurance that your building and its occupants are safer from seismic disruption.

DESIGN/PERMITTING From site visit to approval by the City:  about 1 month  

CONSTRUCTION  Start-to-finish for seismic retrofits:  average 6-8 weeks  


We take pride in streamlining the design and construction process, eliminating client stress and ensuring your project is completed on schedule. You’ll never be left having to navigate the permitting process - we take care of everything.  Nor will you find construction taking months longer than anticipated.  We stand by our promises, and our satisfied repeat clients are a warranty of service quality and reliability.
