Building Statistics - Part II
Primary Systems:
Structural
Building Framing for the Firing Range will be open web steel joists which provide clear span oping without columns in the range area. The structure will be designed to support a ballistic containment steel baffle system and a ricochet ceiling system. The firing range walls are load bearing construction. The walls will be constructed of reinforce/solid grouted CMU with a split face block facade. The solid grout filling is necessary for ballistic containment. The training area will be a steel framed structure. The second floor framing will include columns. the roof framing will be clear span with no columns in the second floor.
Mechanical
Electrical
Electrical service is fed from an existing BG&E 13.8 kv primary overhead 3-phase lines. A 1600 amp, 480 volt, 3phase, 4-wire switchboard will be provided at the serve entrance. The main switchboard will serve panels rated at 480Y/277, which will power mechanical equipment, luminaires, and stepdown transformers to feed appliance and special lighting panels serving 120 volt loads, including receptacles. A dedicated panel will provide power to the exit signes, the exit or night lights, the elevator cab and machine room lights, and the security and fire alarm systems. Emergency power is supplied by a 480 kW generator at 480/277 volts during power failures.
Lighting
Fluorescent: recessed type 2x4 fixutres, pendant industrial type 0.5x4 fixtures, and round compact type fixtures
Incandescent: flood and recessed types
Metal Halide: wall mounted
High Pressure Sodium: pendant type indoors and square pole mounted oudoors on 30 foot aluminum poles
Weathertight: located outdoors, in the toilet and locker rooms, elevator pit, and janitor room.
Explosion Proof and Corrosion Resistant: fixtures with these ratings to be used in specified areas.
Controls: All indoor lights will be operated from local switches and the Range control room will have a master control panel in the Control Room for all range fixtures. General lighting luminaires can also be operated from the range entrance. All exterior lights will be controlled by photocells.
Supporting Systems:
Communications/Data Systems
A raceway system only will be provided for the telephone system. Cables will be brought by Verizon in two 4” PVC conduits (conduits provided by owner) that will be run underground from the board to a pole East of the building perimeter road and connect to the existing overhead telephone lines.
A raceway system only will be provided for the computer network as well. One data outlet per workstation at offices, classrooms, reception, Weapon Repair room, control room, and Weapon Cleaning room are provided. All outlet conduits shall be run underground to a 4’x8’x0.75’ thick board in Electrical Room 117.
Access Control (Security) System
A controlled access security system is capable of recording, reporting, and alarming locally and remotely based on a set of detectors within the facility. Magnetic Switches are provided at exit doors and doors into weapons and ammunition storage rooms, the control room, the weapons cleaning and the repair rooms. Door entry controllers are located at the entry doors to the Weapons and Ammunition Storage rooms. Movement Sensors are provided at the weapons and ammunition storage rooms.
Fire Alarm System
The system is a multiplex addressable type with the main panel in the electrical room and the annunciator in the reception room connected via a telephone dialer to the fire department or a remote monitoring service company. Pull stations, audio/visual signals, duct detectors, smoke detectors, and head detectors are located throughout the building.
Closed Circuit TV (CCTV)
A Closed Circuit TV system is utilized with a monitoring console at the reception desk.
TV Antenna System
TV Antenna System is provided via a concealed raceway system with an antenna system connected to a roof mounted dish to pick up regular broadcasting and other signals put out by the state and federal agencies. TV outlets are provided in each classroom for the ceiling mounted TV set.
