Applicable Standards and Codes

• Department Of Veterans Affairs: Mechanical Design Manual. • VA Standard Details and Specifications • IMC-2015, International Mechanical Code • IEBC-2015, International Existing Building Code • ASME A17.1-2016, Safety Code for Elevators and Escalators • NFPA 101, Life Safety Code. Project Overview and Existing Conditions The project involves replacing ten existing elevators in ten buildings at the Coatesville, PA Veterans Administration Medical Center (VA). These buildings are numbers 2, 4, 5, 6, 7, 8, 38, 39, 57, and 58. Each building is three-levels with an attic, except Building 5 which has two levels, with level numbering Basement, 1st Floor, 2nd Floor, and Attic. The actual elevator replacement will be by others and the focus of Apogee’s efforts will be mechanical, electrical, and architectural support for the ancillary systems within the affected buildings. The elevator machine rooms for Buildings 4, 5, 7, 57, and 58 are on the basement level of the building, while the machine rooms for buildings 2, 6, 8, 38, and 39 are in the attic of the building, above the elevator shaft. None of the machine spaces and elevator shafts are fully compliant with current Applicable Standards and Codes, and the project will bring each elevator shaft to compliance. This involves demolition or relocation of equipment in machine spaces. PROPOSED DESIGN AND WORK REQUIRED FOR ELEVATOR REPLACEMENT Proposed general design and mechanical work required for each of the ten buildings is described below. Details are provided for cost estimation purposes. Elevator Sump Pump System in Pit Provide elevator sump pump system in pits for all 10 buildings. The existing pit will be re-used for Building 5. All other buildings will have new pits added. All pits will have a sensor to detect and differentiate between water and oil, and to disable the sump pump and annunciate and alarm at BMS workstation upon oil detection. An alarm will annunciate at BMS workstation upon pump activation for high water and at oil detection in the sump. The pumped discharge drain will be through the exterior wall with 45° elbow, turned down, at the discharge location. Elevator Lobbies Remodels Remove and replace the existing fire sprinkler heads, grilles, and diffusers in the remodeled areas of the various elevator lobby areas in all building. Existing piping and ductwork will be modified as needed to slightly relocate the devices to fit within the remodeled ceilings. Elevator Machine Room Split System Heat Pump Each of the 10 Elevator Machine Rooms will have a Split System Heat Pump with Indoor Unit Fan Coil, mounted high on the wall with approximately 22,000 btu/hr cooling capacity, 28,000 Btu/hr heating capacity. The outdoor (air cooled) heat pump will be installed on an 18” high roof curb at nearest point available on roof or mounted near an exterior wall on a concrete pad and 18” high support frame. There Project Name: Coatesville Replace 10 Elevators Apogee Project Number: 14-273 Date: 15 May 2017 will be 3 ft. clearance around outdoor heat pump on all open sides. The controls for the systems shall be self-contained, but the rooms will be monitored by current building digital control systems. Where the buildings do not have a current digital control system, the equipment to hook to a future system will be installed. Shaft Ventilation Fan Replace existing shaft ventilation fan. Ductwork will remain. Provide new dampers and actuators in ductwork. Provide new ducted transition with flexible connections from existing 24x24 exhaust duct to new exhaust fan. Fire wrap insulation will be added to the ductwork to maintain a fire-rated assembly from the rated shaft to the exterior. Controls will be reconnected to activate from the replaced smoke detector in the top of the elevator shaft. Relocation or Alteration of Existing Systems within the Elevator Machine Rooms Many of the existing machine rooms are not enclosed in a room in accordance with ASME A17.1, a new room will be built around several of the existing machine spaces.
