No, not really. The walkway runs the entire length of the building so I would wind up sprinklering the entire attic.
My state requires a Nicet III for design, installation and inspection. Our guys are pretty good about sticking with the design. If a problem arises they call the office, even if I mis-cut a hanger rod I hear about it. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ron Greenman Sent: Thursday, April 17, 2008 9:58 AM To: [email protected] Subject: Re: Mechanical access walkway Russell, if a single row of heads is the goal have you thought of attic heads. And by the way, that fitter that re-designed things that I complained to you about thinking you were a different Russell has been told in no uncertain terms that he may think a little sometimes but cannot do any thinking in the demand area unless he gets design training, gets his NICET III and then receives certification from the State.
