I know there are quite a few individuals out there who work with the UFC 3-600-01.
Perhaps we can start a discussion about the application of the DoD 13R criteria. After working a number of jobs using NFPA 13R I find the application of this document is not clearly defined in UFC 3-600-01. We have already discussed the use of 13R in a mixed use building (can't do it per the IBC but maybe not so clear per UFC 3-600-01). My suggested DoD 13R approach: 1. Inside the dwelling unit use the calculation criteria from NFPA 13R (not UFC Table 4-1), supplemented by UFGS 21 21 00, 1.3.2. 2. Sprinkler calculation outside the dwelling unit would be per NFPA 13 and not Table 4-1 in the UFC (3000 sq ft with ceiling height reduction, etc). 3. Room design rule can be applied (vs full 3000 sq ft with ceiling height reduction) outside the dwelling unit. 4. No hose stream (vs a hint that some hose stream should be applied by the fill-in-the-blank spot in UFGS 21 21 00, ). For four story buildings a standpipe system is required, but the water supply will most likely be supplied by the local fire department. I've requested clarification on this topic without success, but I wanted to put a set of guidelines out there for discussion. Questions: 1. How are the list members now applying 13R for DoD work? 2. Have any of you ever received specific guidance from DoD reps on this topic? Bill Brooks William N. Brooks, P.E.
