Fire suppression systems should be provided for facilities in accordance with UFC 3-600-01 and applicable NFPA criteria. System designs should be the performance- based type with detailed shop drawings, materials submittals, and hydraulic calculations prepared by qualified technicians. Installation of as required by UFC Standpipe and Hose Systems and NFPA standards Installation of Sprinkler Systems.
Tailor the sprinkler design criteria (occupancy, design area, density, hose demand, etc.) specifically for each building. Identify all of the performance criteria for the main library and business occupancy areas. The criteria should be specific. The drawings should identify the arrangement of the bookshelves, bookshelf height, clearance, items being stored, K-factor, number of heads operating, minimum pressure, hose demand, etc. such that the Government or Contractor does not have search NFPA 13 for the criteria or argue about the commodity, maximum storage height, etc.
Show the incoming water supply line location and risers. The riser has to be fully detailed complete with identifying all valves, switches, and piping. The conceptual design begins downstream of the riser and not at the pump. Important items need to be shown
pictorially to indicate the design intent. The detail callouts on the plan need to match detail sheets. Show the layout and size of all piping and equipment from the point of connection to the water supply, to the sprinkler cross mains. The contract drawings should include a detailed sprinkler riser diagram. Show location and size of service mains, interior feed mains, control valves, sprinkler risers, drain lines, sectional valves, and inspector's test valves and switches on the drawings. Specify water flow data including hydrant flow results, including the location where the hydrant flow test was conducted, on the drawings. Indicate the location and size of existing mains and new water supply lines that will serve the sprinkler system (including all supervisory valves), and the location and size of all risers on the plans. Highlight or clearly indicate the area(s) to be protected by sprinklers on the drawings. Specify waterflow requirements including the design density, design area, the hose stream demand (including location of the hose stream demand), the duration of supply, and sprinkler spacing and area of coverage on the drawings. Show the location of the backflow preventer (including provisions for a drain and access for maintenance) where the potable water supply system is at risk of contamination by the sprinkler system on the drawings.
101 When connecting to an existing water distribution system, waterflow tests will be conducted in accordance with UFC 3-600-01 to determine available water supply for the sprinkler system. The Designer of Record should either perform or witness the waterflow test. The waterflow test results (including date test is performed) should be included in be included in the design documents no later than the concept submission. Note that the availability of the Designer to participate or witness the waterflow test will be necessary.
Provide hydraulic calculations and sketches complete with nodes, pipes,
sprinklers, etc. The hydraulic calculations to follow the format of NFPA 13 to support the conceptual design and submitted in the Basis of Design. The designer (a fire protection engineer) must provide hydraulic calculations demonstrating that the design will provide an adequate water supply for the fire extinguishing system. Hydraulic calculations must be submitted before the first submittal. The A/E needs to provide hydraulic calculations based on a conceptual layout. Not rough conceptual calculations.
Commissioning requirements for Army, Air Force, and other Department of Defense facilities are outlined by UFC 1-200-02 High Performance and Sustainable Building Requirements, ASHRAE Standard 189.1 Standard for the Design of High- Performance Green Buildings, and Engineering Regulation 1110-345-723 Total Building Commissioning Procedures. If a project has a Leadership in Energy and Environmental Design (LEED) requirement, commissioning requirements are imposed by the LEED Rating Systems. The design publications listed below should be used as sources of criteria for commissioning. The criteria from these sources may be supplemented, but not supplanted, by applicable criteria contained in nationally recognized codes, standards, and specifications.
Once the facility has been commissioned and accepted, maintenance of the facility shall be done by the facility owner which is the Department of the Navy,
Yokosuka Naval Base, Department of Public Works in this case. Maintenance of the fire suppression system will be carried our in accordance with the UFC 3-600-01 and best practices. The fire pumps will be periodically tested (3-6 months) by the Yokkosuka Fire Department and Yokosuka Public Works Department. Other system components such as backflow preventers, risers, and other components will be periodically tested as specified by the manufacturer’s preventative maintenance recommendations.
This is a comprehensive report on the fire suppression system for NA893
Community Support Facility at Yokosuka Naval Base. This facility has many functions to include the main library, education center, clinical space, and other administrative functions.
This facility is a 4 story, reinforced concrete structure. The administrative, clinical, and educational portion of the facility has been classified as a Light Hazard Occupancy. The water suppression demand for this portion of the facility has been calculated to be 116.0 gpm at 36.2 psi.
The main library portion of the facility is located on the first floor. The library portion of the facility has been classified as a Ordinary Hazard Group 2 Occupancy. The water suppression demand for this portion of the facility has been calculated to be 146.8 gpm at 47.1 psi.
Based on the water supply information, there is amply flow and pressure to meet the fire suppression system requirements for the subject facility even with a 30-40% drop in water supply. Although not required by US codes and regulations, a fire pump and cistern will be installed based on the Japanese Fire Standard Law.
