EARTHQUAKE BRACE & BOLT
Seismic Strengthening and Retrofit Services
Earthquake retrofitting is performed to keep your home from being displaced from its foundation. In California, the need for seismic strengthening is substantial and valid. According to a New York Times article published in December 2011, one-third to two-thirds of earthquake retrofits in the San Francisco Bay Area are installed incorrectly. One’s home may still be vulnerable to serious earthquake damage if a contractor without formal education and training in calculating seismic forces, alternate load path, diaphragm action and other critical functionality is engaged to attempt retrofit services.
Why Is Tracery Professional Builders, Inc. Highly Qualified to Handle
Mark Macdonald, our founder and president, has degrees in both Structural Engineering and Civil Engineering and has been certified as a FEMA-Trained Brace and Bolt Contractor. As stated on earthquakesafety.com there is “no such thing as a standard house or a standard earthquake retrofit.” It is essential to hire a contractor with experience and training, one who can do the calculations correctly, in order to appropriately reduce the risk of earthquake damage.

Frequently Asked Questions
Approximately how much does the permit cost?
Permit costs vary from city to city. To get an appropriate estimate, we advise you call your city and speak to a permit technician.
Can my family stay at home while the work is performed?
Yes. We kindly ask family members to avoid or stay cautious of the surrounding area near the crawl space. There will be miscellaneous items that may be hazardous such as power tools, electrical cords, foundation materials, etc. We do our best to maintain cleanliness and organization on all our job sites, but a high sense of awareness is very important. If no one will be home, we advise installing a lock box with a spare key.
Do I need to rent a portable toilet?
If a bathroom is available on site for use during the duration of the work, renting a temporary toilet would not be necessary.
T-Strap and L-Strap (illustrated on SK-C and SK-D) are optional for about $1000?
This option is not included with the amount proposed in the estimate. This type of extra bracing is not required by the EBB program. We offer this to you as an option to add extra strengthening to the posts in your foundation.
Since we are accepted by FEMA EBB, will you provide documentation including taking pictures?
Yes. Tracery will take care of all documentation required by the program including: before and after pictures, obtaining the permit, scheduling inspections and final invoicing.
