I too agree that a set screw coupling has cost and installation advantages over the compression conduit fittings, when properly used. Some of the specification pages are "Boiler Plate" and just printed out and added to any RFQ with out being checked or read thoroughly. One can bid "As Specified" and then add as an addendum package/pages to their bid that would show cost advantages by implementing some or all the suggested recommendations in the addendum. This way the company requesting the bid will get an actual bid as they requested, but also receive information on cost saving methods and/or materials. This would demonstrate that they are dealing with a contractor that understands the bottom line and is willing to help keep costs in line.

I have been on both sides of the fence, as a contractor responding to RFQ's and also preparing, issuing, and evaluating the received bid package from contractors. A contractor who gives suggestions how to reduce costs was always appreciated and carefully considered, generally more than a contractor that submitted a straight bid.

Just my two cents..
