Abstract
Protected membrane roofing is a relatively new concept that is currently under development by USA CRREL. A major problem with continued development is the reluctance of designers and contractors to specify and bid on this roofing procedure. This paper reports on the construction of a protected membrane roof on the CRREL lab at Hanover, N.H. It includes discussions of the bidding procedure, cost breakdown as supplied by the contractor and photographic coverage of the various construction procedures. The concept proved to be material-sensitive rather than labor- sensitive. A pre-bid conference with potential bidders was found to be valuable. The completed roof has performed satisfactorily.
