What is Seismic Retrofit?

Seismic retrofit is the modification of existing structures to make them become more resistant toward earthquake damages and ground motion. Earthquake retrofitting is done to help make your home a safer place to live and reduce your financial property cost when an earthquake may strike. According to the Federal Emergency Management Agency, the average annual cost of earthquake losses in the United States is approximately $4.4 billion, among which California damage accounted for $3.3 billion, among which California accounted for most of the cost.

Why Do You Need To Have Your Property Retrofitted?

Living in active seismic zones, you must always take into consideration the safety of your family, your employees, business, and property value. Since earthquake activities are unpredictable, retrofitting your house or business buildings is not only a smart decision but also a cost-effective approach for your property insurance budget.

In addition, the city of Los Angeles and San Francisco recently approved a comprehensive seismic retrofit ordinances that mandate certain building types to have structural improvement.

What is the process for Seismic and Earthquake retrofitting?

There are several stages within a seismic retrofit project. In some cases, depending on your property structures, you might need to go through all the stages, while others you may not. Penhall recognizes that each building has its own unique features. As a result, in the beginning, we provide free property assessment for any incoming inquiries to help you better understand your retrofit needs. However, Engineer Phase is necessary in any seismic retrofit project to meet the ordinance requirements. During engineering, our team will perform building measurement, non-destructive testing, and CAD design to create a plan to be submitted for city approval. Construction Phase is not applicable to all projects. Below is an estimated timeline for Penhall Seismic service:
