Resources and Checklists for Plan Review, Inspection, and Design
Automatic sprinkler systems can be complex life safety systems which require maintenance and proper installation. Automatic sprinkler systems are based on the National Fire Protection Association (NFPA) 13, Standard for Design and Installation of Sprinkler Systems. Sprinkler systems require proper design, installation, and maintenance (inspection too).
Sprinkler submittals are usually prepared as show drawings or deferred submittals under the adopted building code. The shop drawings are typically prepared by the installing contractor although some projects they are prepared by the design professional or fire protection engineer. Sprinkler systems must be designed based on the use of the space, not necessary the classification of the occupancy under the building code.
Proper plan review will look to ensure adequate informaiton is provided to compare the design to the anticipated use, sprinkler spacing, and proper informaiton is included in the design calculations. NFPA 13 provides a very detailed listing of information required on the shop drawings and calculations in Chapter 22 (2007 edition). Contractors should refer to this chapter to ensure shop drawings meet the minimum requirements.
You can view all of our educational posts on sprinklers here. The following resources will aid in the inspection, plan review, and maintenance of sprinkler systems.
- Resources for forward flow of back-flow devices
- FM Data Sheets are now free and available on line. These data sheets are used by many businesses and insurance carriers to protect the interests of the property. Many times the requirements meet or exceed those identified in NFPA 13.
- Did you know that if you have a 4″ riser or less, the designer shall account for the friction loss of the paddle flow switch? See the potter memo for more
