Probable Maximum Loss

The Probable Maximum Loss, the PML, is the premier tool used by real estate investors and lenders to evaluate how buildings will behave during a seismic event. Partner's clients can trust that the PML report will accurately identify assets with high seismic risk.

To assist in the underwriting transaction, Partner performs Seismic Damageability Assessment/Probable Maximum Loss reports. In preparing a PML, Partner evaluates the likely costs incurred from seismic damage to structures on a given site. Partner's licensed engineers inspect and discuss building types, critical connections, local soil conditions, and local seismic activity to use in calculating the PML for 50 years and/or 500 years. The PML is intended to suggest how the property will be affected by a probable seismic event, not guarantee how the property will perform in a seismic occurrence.

Partner prepares PMLs to meet the requirements of the scope of work defined by ASTM E 2026-99 Standard Guide for Estimation of Building Damageability in Earthquakes (the Standard), as well as adhering to Scenario Upper Loss (SUL) as identified in the Standard. Partner also utilizes the Modified Mercalli Intensity Scale to consider the reduction, or attenuation, or ground motion at the distance between source and site increases, the scale is calibrated I to XII.
