Our seismic risk reports are prepared in accordance with the guidelines defined in ASTM 2026 “Standard Guide for Seismic Risk Assessment of Buildings” and ASTM 2557 “Standard Practice for Probable Maximum Loss (PML) Evaluations for Earthquake Due-Diligence Assessments”. These guides provide a uniform approach and a standard of care for the evaluation and classification of risks from earthquake damage. The procedures underlying our assessments rely on methods developed by reputable researchers (Thiel & Zsutty) and accepted as an industry standard. Risk assessments (damage loss estimates or probable maximum losses) are often required by Commercial Mortgage Backed Securities (CMBS), Fannie Mae and Freddie Mac loan underwriters. Sesimic risk assessments (PML) use probabilistic methods to determine the seismic risk in the building. Seismic evaluations use structural analysis to determine the seismic performance of the building. Click "more seismic risk" to learn additional details and requirements for your consideration.
