Thank you Gerard, this is exactly the type of
education I was looking for. Is this something that the typical
engineering firm should expect to be asked to do (ie. something we should be
prepared to offer in the future) or are there firms that specialize in risk

stands for Probable Maximum Loss. It is a study using traditional engineering
methods to determine weaknesses and then assigning a risk. The PML methods are
published by SEAOC, I think Zsutty is the major contributor to the methods.
Degenkolb has a software called STRISK that can do all the number crunching
and produce some graphics.
PML is valuable tool for insurance people and lending institutions because it
quantifies the cost of repairs (in very general terms) compared to its value
in simple layman's terms. The PML number (A percentage) attempts to quantify
the cost of repairs to the structure to make it function again after a
major seismic event. ie. if the PML number was 26%, if would cost 26% of the
structures current value/cost to make it usable again after a major quake.
This number can decide insurance rates or whether or not a retrofit will get
of times, a PML is generated for current condition and retrofitted condition
(if it's in the budget to investigate the possible retrofit
best bet is to get the binders from SEAOC.
A client on a current project is requesting
referrals to provide a PML report regarding seismic issues. I am
unfamiliar with PML reports (Possible Major Loss?).
Any help and education would be
