Average Time Of A Retrofit

The answer to this question depends on a variety of factors, mainly the size and scope of your individual seismic retrofit project. Each property is unique and requires a different solution than another, so understand that your project may be shorter than the average project or longer than average project.

The process is as follows:

  1. Once you have chosen your engineer and contractor for your seismic retrofit the process can be broken into three steps. The engineering process tends to take, on average,  2-4 weeks. Your property needs to be assessed and it takes time for the engineer to determine the best seismic solution for your property.
  2. Once your engineer has returned with the plans they must be submitted to the city for approval. The city will determine if the plans the engineer has proposed are appropriate. This can take as little as 6 weeks and up to 12 weeks. If desired, an expedited plan check is available though there is a fee associated with this service.
  3. Once the plan is checked and approved, construction can begin. The time for construction is dependent on the size of the property that is being retrofitted. On average construction takes 30 days but this time frame will increase if the complex is larger.
    When the engineering process is completed, the construction portion of the retrofit begins.

As mentioned, time can vary considerably based on the size and scope of the work. On average, construction takes approximately 30 days. However larger and more complex work requires more time (greater than 30 days).

The retrofit process may seem daunting, especially considering that some may even have been unfamiliar with the term “seismic retrofit” prior to receiving their notice. However, there are great resources to learn everything you need to know about the seismic retrofit process.
