Hello All,
Looking for clarification on the fire line approval process:
In my previous company many contractors came to us to produce stamped and signed Fire Line Shop drawings. These drawings were based off the original site design construction documents. The original documents would show the fire line along with location of Fire hydrants, PIVs, FDCs CV, BFPs and thrust blocks. However, the various fire departments would still require fire shop drawings as the fire line installation was deemed a delayed submittal that require separate approval by the fire department.
In some cases, the shop drawings were simply be a repetition of the design drawings with part numbers and sometimes a bit more detail than shown in the original design drawings. Based on my training, my supervisor constantly made a distinction between items that were "design issues" to be addressed by the original "design engineer" and items that would need to be addressed by the shop drawing engineer. I have followed the process before: Take design documents, specifications and hydraulic calculations to produce shop drawings. Shop drawings and sometimes even calculations are submitted to fire department for approval. Fire Line gets built by the contractor and signed off by fire inspector.
So the question is: How much information is to be provided in the design drawings? and how much goes in the shop drawings? I may be answering my own question, but why would a contractor need to produce signed and stamped drawings if there is plenty of detail in the original design document?
I have been in situations, were there has been plenty of detail in the design documents for construction and still shop drawings are required. This issue pertains to installation in California. Your input is greatly appreciated.
