It's nice if you have time to ask questions prior to bid. Just finishing up a quote today. 425,000 sq. ft. ESFR. Pump size is specified 2500 @ 65, the specifications also call for ESFR-25's. Based on the available water supply, the pump needs to be 95 psi. @ 2000 gpm . The 2500 gpm pump will draw the supply down to 0 at about 130% of capacity. We are just going to qualify the hell out of the bid.
Invitation to bid 3-4-14, bid date 3-12-14, doesn't leave much time for clarifications, I just received the flow test info this AM. Richard L.

An engineering firm had subbed out a High Expansion Foam job to us, and our spec apparently then became the basis for their standard sprinkler spec. Contractors in this industry are so used to schlock spec's that they too often ignore items added by legitimate EOR's. If all contractors actually questioned the ME's prior to bid, and copied the Architect, it would put pressure on the ME's to clean up their act and actually modify the spec as needed by the current job. But few contractors have time, and the ones who are used to bidding off certain EOR's 'know' what's enforced and what isn't, thereby giving them a competitive advantage versus anybody not familiar with that particular engineer. When I worked with Mark we used to joke about adding a clause at the beginning of each spec: "Note: We really, really, really, really mean what we say in this spec." David M.
