Need Some quick Direction...

Hello Everyone,

I've had a situation come up and I eagerly await any and all suggestions anyone can offer:

Ok, first a little background on the project: I am a designer and project manager for a small U.S. based company that manufactures and installs water meter test systems. One of the projects I am currently involved in is for the City of Calgary, CA. The system is split between two floors with a recirc tank and pumps being downstairs and the test equipment upstairs. This was all decided upon very early in the building design & construction phase and all involved were made aware of exactly where we needed to pass 8" sch40 c/s pipe through the floor. The system was reciently delivered on-site for an up-coming installation.

Now for my "problem": The construction company dropped the ball. They made absolutely no allowances to pass pipe through the floor in the two locations we required. Once we discovered this we hired a company to x-ray these locations to see if we could core-drill. In one of the two locations we are clear of any rebar. We are not so lucky with the other. The building contractor representative refuses to allow us to cut through any rebar in the second location. The buildings designer can not be reached: she's out on maternity leave.

Now for my question: Has anyone else out there ran accross, or are aware of, any method of effectively reinforcing a prestressed, reinforced concrete floor prior to or after core-drilling in a similar situation?

I just returned from Canada after a meeting with all involved in the project except the building contractor. They just didn't show up. Ideally, what I want is a "ring" or "sleeve" type device to restore any structural weakness created by removing one 10" piece of rebar.

In my openion, It's not going to hurt anything to drill the hole but I'm not a structural engineer so I can't put up a valid argument. What I can do is seek lagitimate options to present to them.

Sorry soo long...
Thanks,
