Another reason to have a peer group if not just a circle of friends.... When I was with ASCOA, and we were doing Chrysler's "A" Body paint building in DE, we had to avoid exposed silicone rubbers. One call to the district designer in Detroit office and I knew what changes had to be made in some trim packages.
Certainly better to find the answer than re-invent the wheel! glc -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: Wednesday, August 12, 2009 7:48 AM To: [email protected] Subject: Re: Low Air Pressure Alarm Device - Gov't Project Mark, The government is in a unique position to not limit competition by naming specific manufacturers of specialty items,particularly if the desired item is only made by one manufacturer.They get around this by writing a specification that can ONLY be satisfied by the desired componant.Sounds like a conspiracy theory,but it really isn't.They are just attempting to get what they want and nothing less(they may have their reasons). If possible,try and find a competitor who may have done a similar project with the same branch of the government(GSA,AEC,etc.).If this fails,try and make direct contact with the spec. writer,he may tell you(off the record)where to find it.
