Denver Service Center (DSC) Requirements


  • A Code Analysis is required and shall be based on NFPA 1 (Fire Code), NFPA 101 (Life Safety Code), and the I codes. Other applicable NFPA Codes and Standards shall be identified in the Analysis. The Code Analysis shall include, but not be limited to, the following elements:
    • General Description of the Project
    • General Fire Resistive Construction Aspects
    • Occupancy Classifications
    • Fire Resistive Separations
    • Doors and Windows
    • Interior Wall, Ceiling and Floor Finishes
    • Decorative Structures within Buildings
    • Egress
    • Special Design
    • Emergency Signage
    • Suppression Systems
    • Fire Department Access
    • Fire Detection and Alarm System
    • Emergency Communication Systems
    • Smoke Management Description
    • Central Control Station
    • Emergency and Standby Power
    • Elevators

Fire Systems

  • Wet pipe sprinkler systems are preferred.
  • A double check backflow preventer is required on sprinkler systems.
  • Sprinkler control valves shall be electrically supervised.
  • Allowed sprinkler piping shall be Copper, Schedule 40 steel, or plastic.
  • Dry Pipe and PreAction Systems
    • Joints shall be threaded or cut groove (no roll groove).
    • All pendent heads shall be dry pendants.
    • All piping shall be sloped to drain to the main riser.
    • Low point drains shall be minimized and shall be configured as drum drips.


  • The facility shall be compliant with OSHA requirements.
  • Hazards shall be mitigated using engineered solutions.
  • Confined Spaces shall be eliminated wherever possible.

Professional Guidance

General Design Guidance

  • Code Equivalencies are encouraged. They need to be prepared by the Architect-Engineer (AE) for approval by the Regional Fire Marshal (Authority Having Jurisdiction (AHJ)).
  • Fire modeling is encouraged to allow equivalent fire and life safety systems, especially in historical structures.
  • Systems should strive to minimize required (NFPA 25) Inspection, Testing, and Maintenance.
  • Gravity water supply systems are preferred. Next are combined fire and domestic systems using commercial pumps and least preferred are dedicated fire pumps.
