Retrofit1
We have over 20 years of construction & design experience. We have a full staff of professionals to manage the soft-story retrofit process – including the tenant habitability plan, the construction, and the cost recovery at the end. Each project is assigned a project manager to keep construction on schedule and budget.
It all starts with the right plan. Drafting and submitting the most economical plan is crucial to saving you construction costs. At Retrofit 1 our engineers provide a cost effective approach to seismic retrofitting by visiting the site to do pre-construction invasive testing, and we take our own pictures. The engineer then uses that important information to design a solution for your building that uses the least amount of steel and other material to save you money on construction!
Trusted for delivering reliable seismic retrofitting solutions that stand the test of time.
