Minimum Fire Sprinkler Design Criteria
Instructions
NFPA Standard 13 is to be used as a guide for the design and installation of fire sprinkler systems at BYU. However, NFPA 13 is only a minimum standard. This document will serve as an additional specification for all new or retrofit fire sprinkler installations.
Fire Protection
1. At the completion of the project, the fire sprinkler contractor shall submit to the BYU Construction Department one (1) set of "Mylar" fire sprinkler system as-built drawings or one (1) set of AutoCAD drawing files (.dwg) on a compact disk.
2. The University Insurance Carrier is to be specified as an approval authority. Prior to job bidding, specific detailed rulings can be obtained by contacting the BYU Construction Department, the BYU Risk Management and Safety Department, and/or the University Insurance Carrier.
Submittals
Sprinkler Contractors are to provide the General Contractor with nine (9) copies, and the Provo City Fire Department with two (2) copies of the shop drawings. The General Contractor is to deliver or mail copies of the drawings to the following:
Shop Drawings to be Delivered To Number of Copies
General Contractor 1 Copy
Architect 1 Copy
Engineer 2 Copies (Returns one copy with comments to Contractor)
University Construction Coordinator 5 Copies
The University Construction Coordinator will distribute received shop drawings as follows:
University Construction Coordinator 1 Copy
University Utility Director 2 Copies (Returns one copy with comments to Construction Coordinator)
University Fire Marshal 2 Copies (Returns two copies with comments to Construction Coordinator)
Final Submittals
Sprinkler contractors shall correct drawings, incorporating comments and shall submit written comments addressing each comment as noted above. Corrected drawings shall be resubmitted, with nine (9) copies being sent out for review as noted above.
MINIMUM FIRE SPRINKLER DESIGN CRITERIA February 16, 2007 2

The University Fire Marshal will deliver or send copies of the shop drawings to the University Insurance carrier. The University Fire Marshal will correlate with the assigned BYU Construction
Coordinator so that plan review comments from the University Insurance Carrier are returned expeditiously.
Approval of shop drawings must be obtained prior to installation. Questions can be forwarded to the University Construction Coordinator and/or the Campus Fire Marshal.
3. All codes and regulations listed pertaining to fire protection shall be complied with. In addition, code(s) adopted by the Utah State Fire Marshals office shall apply.
4. All new installations or retrofit applications required by code where it is necessary to install fire protection systems where commercial cooking is conducted, or cooking areas where grease laden vapors are produced, are to meet the requirements as set forth by the University Insurance carrier, and the BYU Risk Management and Safety Department. Required specifications for the installation of fire suppression equipment designed for the protection of commercial cooking operations can be obtained at the Risk Management and Safety Office. Contact the BYU Campus Fire Marshal for more details.
5. All fire sprinkler designs involving more than 100 sprinkler heads are to be based on a current flow test of the available water supply. The contractor is responsible to conduct the water supply flow tests. Flow tests are to be witnessed by the University Fire Marshal or his designee. Flow test analysis and calculations are to be submitted along with all shop drawings. Where city water provides the sole fire protection water supply, hydraulic calculations should utilize no more than 90% of the supply.
6. For hydraulically calculated or performance specified systems, the most recent State adopted edition of NFPA Standard 13 is to be used, however the additional features listed below shall prevail.
a) The entire system shall be designed and installed in accordance with the adopted issue of NFPA Standard 13 and these guidelines.
b) For all hydraulically designed systems the design area shall be the most hydraulically demanding rectangular area having a dimension parallel to the branch lines at least 1.4 times the square root of the area of the sprinkler operation used.
c) Only schedule 40, ASTM 53, A-135, or A-795 pipe shall be used. No foreign pipe is allowed. Piping with alternative wall thickness to schedule 40 is not allowed.
d) A simultaneous 250 gpm hose stream demand shall be included in all calculations where Light Hazard Occupancies exist. A 500 gpm hose stream demand shall be included in all calculations for Ordinary Hazard or Higher Hazard occupancy classifications. If more than 1000 square feet of a building is of a higher occupancy classification, then the entire area, including the lesser hazard classification is to receive a 500 gpm hose stream allotment.
MINIMUM FIRE SPRINKLER DESIGN CRITERIA February 16, 2007 3

e) Design calculations for inside pipe are to include C = 100 for dry pipe and preaction systems, C = 120 for wet and deluge systems.
f) The maximum allowable water velocity in pipe shall not exceed 20 feet per second.
g) Construction scheduling should be such that any water supply connection, underground pipe, or fire hydrant(s) installed are to be tested, and in service as soon as practically possible. Sprinkler installation should begin as soon as roof framing or floors are complete and should be in operation to protect as much of the construction as possible. Existing systems that need to be shut down require the contractor to contact the BYU Construction Coordinator prior to any system shut down. All tests are to be witnessed by the owner’s representative. Contact the BYU Construction Department to schedule tests.
h) A Contractor’s Material and Test Certification for Aboveground Piping must be completed in full and submitted to the University Construction Department representative prior to system acceptance. (See Exhibit "A") Where connection into an underground pipe system occurs, a Contractor’s Material and Test Certificate for Underground Piping must also be submitted. (See Exhibit "B") The lead-in connection to a fire sprinkler riser shall be completely flushed before connection is made to sprinkler piping. The flushing operation shall be continued for a sufficient time to ensure thorough cleaning. The minimum rate of flow shall be that listed in the most recent edition of NFPA Standard 24.
i) Minimum fire sprinkler head operating pressures shall be seven (7) psi. The design of operating sprinkler pressures in the 30 to 70 psi range is recommended. Fire sprinkler heads shall be frangible bulb type. In areas which have finished ceilings, an adjustable concealed fire sprinkler head shall be used. For tile ceilings, the fire sprinkler head shall be located in the center of the tiles. In areas which have no finished ceilings an upright/pendent fire sprinkler head shall be used. The head shall have a chrome finish in areas with unpainted surroundings, or a white finish in areas with painted surroundings.
Approved manufactures are:
· Reliable
· Central
· Victaulic
All models of fire sprinkler heads are to meet this criteria, the criteria of the University Insurance Carrier, and the adopted edition of NFPA 13.
j) Maximum floor areas to be protected by one fire sprinkler system is not to exceed 52,000 sq. ft. for Light Hazard Occupancies, 52,000 sq. ft. for Ordinary Hazard Occupancies, and 40,000 sq. ft. for Extra Hazard Occupancies. For other than hydraulically calculated systems, contact the BYU Construction Department and the University Fire Marshal for assistance.
