Then there's the contractual thing, where they make minor changes like the ceiling guy turns the pattern 90* or shifts it, but they don't want to pay you to make the change. Why should we?
Glc Under 2002 #13 still. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Todd Williams Sent: Wednesday, March 25, 2009 8:01 PM To: [email protected] Subject: RE: Does NFPA 13 require as-built drawings Reality check. "As-builts" are a separate document. They are usually generated from the original design drawing and the fitter's field notes (if he kept them). As to an as-built being exact - good luck. Contractors may keep some notes on what they change, but they are hardly an EXACT duplicate of what is installed (and the assumption is that the designer has access to them). Consequently, as-built drawings at best give you an idea of major changes (main and sprinkler locations) but are far from perfect. There is not enough money or time in any design job for the designer to go out and map out every piece of pipe installed. "If pipe lengths and fittings have changed..."? Outside of number of heads, what else would change? So every job would have to be re-calced. Also, if we have to wait for AHJ approval before any changes are made (22.1.2), nothing will ever get finished. In a perfect world, you are right, but this ain't a perfect world.
