Drilling Post-tensioned slabs - liability
(OP)
We are a small general civil & structural design firm. We frequently receive requests to design minor modifications to all sorts of building types. We have typically shied away from jobs that involve any type of work on PT slabs. The thought being, that if some mishap should occur if a tendon is accidentally cut, and (God forbid) someone is hurt, we would get sued regardless of how many disclaimers we had on the plans.
Now with work being so hard to come by, we are re-thinking this policy. Question is, has anyone else come to terms with this issue? What kind of disclaimers do you use? Require the contractor to do X-rays? Any discussions with your insurance agent on the issue?
Thanks for any suggestions offered.

My opinion (more important, my boss's opinion) is that you should never be so scared of being sued to change your procedures.

"have a local testing lab come out and use a pachometer. This is a simple machine that will locate rebar and cables. X-rays can also be done but they are typically expensive and can be cumbersome tests. A pachometer can be rented for probably 50 bucks for a couple of hours. Remember that these things have a little inherent inaccuracy so leave a few inches clear around things. Also know that if there is conduit on the underside of the slab it will pick that up as well"

The best way to test something is to squeeze it, slowly, until it breaks!
