Date: October 5th, 2017 Project: River Rock Residences Townhouses 72-82 Boston Street Salem, MA Contractor: Difava Fire Protection of MA, Inc. 4 Sheridan Road Wilmington, MA 01887 1 - Building Description: Project Narrative 1- Building Description: * Wood Frame Construction. * Building Footprint = 4,200 sqft approximately * Floors above grade = 3 * Floors below grade = 1 * Occupancies = Residential * Hazardous materials = None known * High storage = None known 2 - Applicable Laws, Regulations, Standards: * NFPA 13 (2013) Installation of Sprinkler Systems * Underwriters Laboratories Inc. Publications * Manufacturer's Listed and Approved Design/Installation/Maintenance Manuals 3 - Design Responsibility for Fire Protection Systems: * Shop drawings developed by Comprehensive Fire Protection LLC. * Fire Alarm by others * Kitchen/Cooking suppression by others * Underground fire service by others * Manual suppression systems by others * Smoke control systems by others 4 - Fire Protection Systems to be installed: The fire protection project consists of installing new sprinklers and pipe in a new building. The system riser consists of a 4" Storz FDC, 4" wet riser, 3" dry riser, 4" water supply, and all other required valves and fittings. 5 — Design Methodology: Fire Sprinkler System Design Parameters: * System(s) design to be per NFPA 13 (2013), local and State code. * Sprinklers on 1st through 3rd floors to be residential type, white coated, recessed pendents or sidewalls. * Sprinklers on garage level to be commercial type. * Install sidewall sprinklers to protect under garage doors. * Calculation area within dwelling units to be the most hydraulically demanding 4 sprinklers calculated to .10 density over the actual area protected. * Calculation of sprinklers in the storage area to be at a density of .20 over 900 sqft using the quick response area reduction allowance. * Calculation of sprinklers in the garage to be at a density of .15 over 1950 sqft after increasing the area by 30% for being a dry system. * The garage and sprinkler room is protected by the dry system. All other areas are protected by the wet system. * Install a zone control assembly for each townhouse unit as shown. * Install steel schedule 10 with grooved fittings or steel schedule 40 with threaded fittings on the garage level. * Install cpvc sprinkler pipe on levels 1-3. CODE REFERENCES: * Design and installation to conform to NFPA 13, 2013 editions. * Design and installation to conform to State Code, Local Fire and Building Departments. 6 - Special considerations and descriptions: * No official code interpretations. * No official waivers or variances. 7 - Sequence of operation: * Fire sprinkler activates. * Water starts flowing and activates the water flow switch. * Water flow switch sends alarm signal to alarm panel and Fire Department. * Building alarm is activated. 8 - Testing criteria: * Tests will be conducted to the satisfaction of local authorities. * Tests to be set up and scheduled by the contractor. * Water will be flowed from the inspector's test valve. * Pipes to be pressure tested to 200 psi for two hours. * All alarm and tamper switches to be tested for proper activation. * Written approval of final tests to be obtained from the code official. * Required fire sprinkler and aboveground piping reports to be submitted to the code officials.
