Under-floor

Postby johnedberg » Fri Jan 15, 2010 10:26 am

Are muicipalities doing a separate inspection for under slab poly and radon? The city of Chaska is doing it at this time to get a handle on working with the contractors for code compliance, but with staffing and work load we are considering if this is really needed. The contractors seem to have it down pretty well. Thanks for any comments.

Until I know that the contractor get it, I'll keep requiring the inspection.

As the contractors say: "Only in Maplewood!"

My question is: is your juristiction requiring the poly be sealed at all laps and penetrations before the concrete crew starts walking all over it? Or are you allowing the slab be sealed from the top side?

I am doing them in Ramsey and finding out the newer contractors do not know why they are doing this.
But I also do a housewrap inspection too. I get lonely and need the interaction or something.

I have been requiring it as it is to new and some of the contractors do not understand it yet.
Also have you looked at increasing your fees to cover your time?

We've been doing this inspection for several years. Unfortunately or fortunately depending on your opinion, we've seen it as an optional requirement worth using. The "requirement" has been in the code since at least the 2000 I-codes. 2000 IRC section R506.2.3 required a 6 mil vapor retarder under concrete floors on ground. Exception 3 would let the BO allow the retader to be omitted if soils conditions were acceptable. Worthington is built in a swamp, basement floors are always wet if not protected. Carpet gets moldy, on and on. We've seen the advantage of this across the board. Sure the contractors complained when we were working this requirement in, but now they're all accustomed to our wierd quirks........ yes that's correct,.......ONLY IN WORTHINGTON..........
Same for the 2000 IBC read section1806.3
06 IRC section 506.2.3
06 IBC section 1807.2.1

Now, about that radon requirement, no deaths have occurred due to radon in Worthington since we've been requiring the underfloor poly...............curious thing about radon, it only picks on the weak and helpless apparently.....no one here fits that description, all tough Southwestern Minnesnowtans.......

Thanks for the responses everyone. I think we'll keep doing it also. I also know of no radon deaths since the code required it, so it must be a good thing. Jim, as far as raising fees, that's the last thing I would do. That in no way would help the inspection department if you know what I mean. Thanks everyone.
