Our seismic assessment services include both initial and detailed evaluations to determine the structural resilience of your building. The Initial Seismic Assessment (ISA) offers a preliminary view of the building’s seismic performance, highlighting potential weaknesses. For a more thorough analysis, our Detailed Seismic Assessment (DSA) provides in-depth insights into the building’s structural integrity, identifying specific areas that require strengthening.
