Submittal Criteria for Sprinkler Plan Review

This is not a complete list, but does highlight frequent errors. The complete specific list of what is required for a full plans review submittal is listed in the 2007 edition of NFPA 13, in Chapter 22, with a list in section 22.1.3. Only 1 set of plans and calculations is required. In general, I look for the following things:

• Plans:

  • Is the Responsible Managing Supervisor indicated on the plans?
  • Is there a site plan? Does the site plan show the water test data relative to the job site?
  • Where are the flow & test hydrants located? How far from the riser?
  • What difference is there in elevation between hydrant test and bottom of riser?
  • Is the site plan detailed enough so that I could use it to find the building in the field?
  • Is North indicated? Are adjacent buildings & roads indicated?
  • Does the riser detail show a way to shut it off?…to drain it?…to sound an alarm...to check the pressure?
  • Does fire pump detail show correct hook-up for both fire pump & jockey pump sensing lines?
  • Where is the inspector's test connection for dry systems?
  • Is there a building cross-section? More than one may be necessary depending upon the building.
  • Are sprinkler head legends complete?
  • Are system capacities noted for dry systems & antifreeze systems?
  • Is the scale indicated?
  • Is coverage complete? Is spacing correct? Are there notations for why some areas are not covered?
  • Are there shutoffs outside of elevator shafts?
  • Are hydraulically remote areas clearly indicated & labeled? Are they of correct size?
  • Is there a hydraulic data summary tag on the print for each remote area?
  • Are there general notes to summarize the scope of the job?
  • When there is storage, are all necessary parameters given, such as commodity type, type of plastic, storage configuration, aisle width, encapsulation, etc?

• Calculations:

  • Are the calcs included with a hydrologrithmic graph done to a legible scale?
  • Has elevation pressure loss been figured in?…backflow preventer pressure loss?
  • Has the hose demand been added in, if required?
  • Is there at least a 7 psi minimum for the hydraulically most remote sprinkler head?
  • Is the density correct for type of head and area of coverage?
  • Are code references and summary given for the rationale for determining the density and remote area size when there is storage?
