RE: PML Reports

[Subject Prev][Subject Next][Thread Prev][Thread Next]
No Problem Paul,
Most engineering firms doing retrofits should be able to perform this task. The engineering is not difficult, it is more of a judgement/experience call in assigning rankings to the various deficiencies of the structure. The process takes into account the type of building, the year of construction, and other quality factors as well.
I guess degenkolb would be the real experts since they developed the software I mentioned. Their website may have some useful info as well as the software price. It's not rocket science though.
good luck.

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 evaluation?

PML 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.
The 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 funding.
Lots of times, a PML is generated for current condition and retrofitted condition (if it's in the budget to investigate the possible retrofit measures).
You best bet is to get the binders from SEAOC.
hope that helps,

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 appreciated.
