With a vast geographical area, comprising of Walnut Creek, Concord, Martinez and the hillside neighborhoods of Orinda and Moraga, each with its own architectural designs as well as seismic problems, Contra Costa County is a vast area. The majority of the older apartments, duplex, and mixed use buildings in these cities were constructed many years before the modern day seismic standards in California. The county has an increasing risk of seismic threat to active fault systems that are operating across the East Bay, as well as diverse terrain such as flat valley floor and steep hillside communities.
Certified retrofitting of soft stories is necessary to reinforce property owners who are so resolute in safeguarding their property investments and enhancing long-term building safety. Retrofit specialists use engineered upgrades, better load paths, and strategic corrections to the lower-level framing to reinforce the weak points to enable lateral forces in buildings. The improvements are beneficial in the prevention of collapse, protection of residents, less liability, and increased longevity of structures across the various neighborhoods of Contra Costa County.

The County of Contra Costa has a number of elevated risk areas related to seismic activity, specifically the hillside neighborhoods, the old commercial areas as well as those constructed on fill or the more prone to soils. The properties within these areas are also prone to lateral motion since the soil in these areas does not behave uniformly and the shaking is also intensified. The reinforcement of these structures using steel framing, bracing and upgrades of shear walls goes a long way in enhancing the capacity of such structures to withstand the seismic stress.
The building is made to be stable with proper load transfer and ground-level reinforcement that allows heavy sway at the ground level, which is the most prevalent cause of soft-story failure. Such upgrades assist in maintaining the security of older buildings, even in areas where seismic activity has been identified to be elevated.

Retrofitting does not necessarily involve massive demolition- most of the solutions are guided to reinforce the buildings with minimal disturbance.
These less significant solutions are easier to upscale the safety of the owners without disturbing the tenants and business activities. Non-intrusive retrofits both provide significant seismic changes and maintain the use and appearance of a building.
We are supported by qualified experience, engineering accuracy and our belief in the reliability of the long-term safety of a building. The property owners of the County of Contra Costa have been trusting us to provide clear assessments, comprehensive reports and the means of reinforcement that will meet the seismic requirement of the local and state laws. Every project is done with precision and consideration so that your building receives protection as it deserves but without any unnecessary complications.
An adequately retrofitted building minimizes the chance of collapsing, safeguards the occupants, and preserves the property value. Having reinforced lower levels, reinforced load paths and enhanced lateral resistance, your building will be much stronger and reliable in the event of another earthquake.
We were very happy with the results of our inspection with Ryan! He explained the settling in homes and what things we should look for, and was very professional, friendly, and efficient. Thanks!
Had a great experience working with Kyndell from Golden Bay Foundation Builders. I recently purchased the home and was looking for help with earthquake retrofitting options. He inspected my foundation carefully and determined that past bolting was likely adequate. He had suggestions about monitoring the foundation. He was very thoughtful and detailed in his approach, and worked to determine what was best for the home. In this case, that meant no need for additional work now. But if I need any additional assistance in the future, will be calling him again.
