Since we're on the topic of contract documents, what do the contractors out there want to see as an ideal level of detail from the PE on plans and specs? I'll throw out some examples based on what I have seen ranging from the minimum (which puts the entire design onus on the contractor) to the maximum (full-blown layout).
1) No design docs - just "design per NFPA 13, 16, 20, 24, etc." 2) Hazard classifications of all areas within the building including densities to be used, size of remote area, etc. - including design criteria for special situations like dry storage of boats, special hazards, and other storage scenarios 3) System type specified - wet, dry, antifreeze, etc. 4) Water supply totally worked out including a coordinated underground design, backflow preventer location and type, and recent flow test info 5) Code references identified for sources of requirements from local building codes and fire codes 6) Fire alarm system interface details 7) Structural coordination details such as locations of mains or standpipes will need to penetrate floors or firewalls 8) Partial layout - such as the location of just mains, or just heads, or just some system components that are critical to the owner or architect 9) Full blown layout and hydraulic calcs (similar to what white paper level of detail) 10) Full blown layout plus stocklisting - contractor just fabricates components and assemblies and entire design responsibility is on the engineer In an ideal world, where every engineer and contractor had NICET 4 knowledge and experience, what would be the ideal level of detail for you as contractors? Does too much information restrict your ability to be creative and bid competitively, or would it be better to have completely engineered drawings to fabricate and install from. I'd love to hear your thoughts. Thanks, Steve Kowkabany, P.E.
