W.G. (Bill) Hefner Department of Veterans Affairs Medical Center 1601 Brenner Avenue Salisbury, North Carolina 28144 2 Subject: Statement of Work: Upgrade PA System Location: Campus Wide Project #: 659-22-201 Date: 04/12/2023 STATEMENT OF WORK SCOPE OF WORK: The Salisbury VAMC would like to expand and upgrade their existing Public Address (PA) System within numerous buildings across their campus. Currently, about 21 buildings have existing paging speakers and cabling that will be re-used. Cable pathways that serve the building s PA system equipment is routed through a campus wide network of tunnels and manholes. In support of the addition of a PA system in buildings 13, 14W, 14E, 15, 16, 17, and 18, existing gypsum board ceilings, acoustic ceiling panels, and other finished concealed locations shall be removed to allow for the installation of the new infrastructure. The existing gypsum board ceilings, acoustic ceiling panels, and other finishes removed shall be patched to match existing. The buildings below have existing paging speakers and cabling that will be re-used: Building 1: Administrations Building Building 2: G. M & S Building Building 3, Outpatient Clinics Building 4: Patient Treatment (Mental Health) Building 5: Main Kitchen Building 6: Recreation Building Building 7: R.M.S. & Core Clinic Building Building 8: Patient Treatment (Mental Health) Building 11, 11A, 11B, 11C: Mental Health Offices Building 12: Police Headquarters Building 19: Chapel Building 20: Laboratory Buildings Building 21: Endoscope, Podiatry, Oncology, Sleep Clinic Building 21A: Fee Basic Building 21B: Engineering Building 31: Chiller Plant Building 42: Gero-Psychiatric Building Building 43: Hospices Building Buildings that do not have a paging system and will require new systems are identified below: Building 9: Parking Garage Building 13: Student Lodging Building 14W: W Duplex Quarters Building 14E: E Duplex Quarters Building 15: Visin Building 16: Laundry Building 17: Warehouse Building 18: Boiler Plant Building 28: Paint Booth Of the buildings that have an existing PA system, eight are fed from other buildings on campus. See below for the locations of source PA equipment and the buildings that they serve: Building 4 serves Building 8. Building 8 will require new control equipment, but no amplifier. Building 8 has amplified speakers that are existing to remain. Building 11 serves Buildings 11A, B, and C. This configuration is to remain. Building 2 serves Building 20. Building 20 will require new headend equipment. Building 21 serves building 21A and 21B. This configuration is to remain. Building 42 serves Building 43. Building 42 will serve 43 with a new dedicated amplifier for building 43 speakers only. EXISTING CONDITIONS: Copper cabling is routed from the main campus backbone, which appears to be within Building 5, to each building s PA system head end equipment. Downstream of the head in equipment, shielded cabling is used to interconnect amplifiers, speaker and rack mounted equipment via conduit, cable tray or j-hooks. PROJECT REQUIREMENTS: The goal of this project will be the installation of new paging equipment and campus wide network infrastructure to support the PA System. Network infrastructure will consist of single-mode fiber ran between equipment locations. New fiber will be routed in new conduit within existing tunnel systems to serve each building s new PA Head End Equipment which will, in turn, provide service downstream to new and existing speakers. New direct buried conduit will be provided in areas where there are no existing tunnel systems. Buildings that currently don t have a PA system will receive new equipment consisting of amplifiers, mixers, speakers in corridors, volume controls, rack mounted or wall mounted cabinets, and associated wiring. The main system will include UPS of battery backup to allow normal operation and function in the event of loss or fluctuations in power for a minimum of 2 hrs. The new PA System will utilize zoning to allow isolated communication to the specific areas as necessary or to allow campus wide messaging when desired. The system will have volume control by zone. Each building where there are current integrations of Fire Alarm, Nurse Call and VoIP systems will continue to be fully integrated in the new system. In buildings where there is no existing Nurse Call, they will not be integrated as a part of this project scope. However, with an IP PA System the integration will be much easier for future systems or buildings with existing Nurse Call Systems even if they are not currently integrated. All PA Head End Units would be replaced as a part of this work. Multi-button microphone stations will be included in Building 12 (Police Headquarters) and Building 21 (specialty Clinics) for capability to call upon separate zones. Per the VA Telecommunications and Special Telecommunications Systems Design Manual, the PA System has been identified as an emergency communications system and performs the Primary Facility NFPA Life Safety Code Blue Team Notification. PA System Head End equipment will be located in existing Telecom Room closets. The PA System will be remote controlled and operated in accordance with VA standards. Existing receptacles on the emergency power systems will serve the new PA equipment. Existing analog speakers will be used with new IP system head ends utilizing a network audio bridge. Reusing existing speakers will not allow for re-zoning of paging speakers in those areas of the VAMC. New speakers will be IP speakers connected via daisy chain and CAT6A cabling. Digital systems do not require End of Line resistors in the same manner as analog systems. New equipment racks and switches will be added as necessary to support the new IP equipment. Construction will be done IAW; VA specifications, Design guides, Infection Control guidelines and all applicable codes. Construction will also be structured to require minimum interruption of space function during construction.
