AHJ Track Track

Review of automatic fire sprinkler system plans has become very complex as the 2016 edition of NFPA 13 was expanded to provide more information than before on fire sprinkler system design and installation. The seminar guides AHJs in a discussion of requirements for plans and calculations contained in Chapter 23, and includes an exercise in hands-on review of a fire sprinkler system plan, including overall design concept, hydraulic calculations, and underground supply system. Evaluation of decisions made by the system designer dealing with hazard and commodity classification, sprinkler selection & spacing, and materials selection are among the topics of this review.  This seminar relies heavily on attendee participation and generates a list of items requiring further clarification or revisions.  A question and answer session will follow completion of the plan review. Plan reviewers and field inspectors should find this seminar helpful, and will most likely find areas where their own review checklist can be modified or improved.  An architect’s scale and a copy of the 2016 edition of NFPA 13 are strongly recommended for attendees.

Upon completion of this seminar, the attendee should be able to:

  • Demonstrate ability to accurately read a set of fire sprinkler plans
  • Perform a thorough review to determine compliance, or lack thereof, with the requirements for fire sprinkler systems in NFPA 13, and their own jurisdiction
  • Calculate the coverage area for each sprinkler, using the SxL=A method from NFPA 13, and identify fire sprinkler locations exceeding coverage limits of NFPA 13
  • Discuss items on the plan in conflict with each other
  • Solve equations to develop minimum flow and pressure requirements for each sprinkler
  • Identify differences between obstructed and unobstructed construction and their impact on sprinkler system design
  • Complete a detailed letter informing the contractor of non-compliance, advising of resubmittal process, describing items deemed non-compliant with references from the standard to support that conclusion.
