STATEMENT OF WORK

Project No. 621-22-144 Bldg. 200 Wings B1 and D1 Renovate VAV Controls James H. Quillen VA Medical Center Mountain Home, Tennessee

PART A – GENERAL

Introduction - The James H. Quillen VA Medical Center (JHQVAMC) has a requirement to renovate the 59 Variable Air Volume (VAV) controls; add 1 VAV box without a reheat coil to the common return and replace the pneumatic controls with direct-digital-controls (DDC) in C120A&B; and add 5 VAV boxes with reheat coils for rooms B119, B138, D119, E119, and E136 with DDC controls. 59 of the VAV boxes in B1 and D1 will have their pneumatic controls (thermostats, reheat valves, VAV controller, and pneumatic actuator) removed and air lines capped and replaced with DDC controls. These DDC controls include Computrols VAV controller, reheat valve with geared-electronic actuator, supply air temperature sensor, and a Computrol’s room thermostat. New VAV boxes with reheat coils will be installed for 6 rooms (B119, B138, C120A&B, D119, E119 and E136). For C120A&B, a new Computrols VAV Controls, reheat valve with geared-electronic actuator, supply air temperature sensor, and a new Computrols room thermostat will be installed on the supply air to the rooms. A new VAV box without a reheat coil will be installed on the common exhaust air of room C120A&B to control the pressure in the rooms. These DDC controls will connect to the Mountain Home VAMC’s existing Computrols system.

1) Scope of Work:

a) The controls contractor shall furnish all labor, materials, programming, and installation of the low voltage components (3 - 8LX controller, 66- VAV controllers, 65 - discharge air temperature sensors, 65 reheat valves and the 65 - MN-S3 room temperature sensors). This includes 1 VAV Controller for rooms C120A and C120B common return; 6 VAV controller, 6 reheat valve, 6 discharge air temperature sensor, and 6 room temperature sensors for the 5 new VAV box with reheat coil for room B119, B138, D119, E119, and E136, and 1 existing VAV supply box for rooms C120A&B; and 59 VAV controls for boxes with reheat coils in B1 and D1. The electrical contractor will pull 120Vac power to every VAV box (66). The controls contractor will wire the reheat valve actuator, installed by mechanical contractor, to the VAV controller. The controls contractor shall install, startup, checkout, Computrols integration and graphics on the Computrols system for the VAV Boxes in Bldg. 200’s Wings B, C, D, and E for the James H. Quillen VA Medical Center.

b) Controls Operations.

i) For VAV controls.

(1) In cooling mode, the controls will work to maintain the temperature set point in the controlled room by varying the VAV’s CFM between the VAV boxes’ maximum and minimum CFM settings. In the heating mode, the VAV box will damper the CFM down to the minimum CFM setting and then modulate the reheat water valve open to maintain the room temperature set point.

c) The controls contractor will train the Mountain Home Maintenance personnel on the operation of the new VAV controllers.

d) The mechanical contractor will install all 66 of the new reheat valves, supplied by the controls’ contractor, for the existing VAV boxes. The mechanical contractor shall furnish and install new VAV boxes with hot water reheat for rooms, B119, B138, D119, E119, and E136. The VAV boxes will be sized to make these rooms’ air pressure positive to their surroundings. The new VAV boxes will need to be connect to the main supply air duct, to the heating water piping, and have their control valves installed with Y-strainer, shutoff valves, unions, and circuit setters to service the coil.

e) On Rooms C120A&B, the supply VAV box has its pneumatic controls replace with DDC. The exhaust gets a VAV box without reheat coils in the common duct work for C120 A&B and a Computrols VAV controller. The VAV on the exhaust is to help maintain the pressures in this isolation room.

f) The electrical contractor will furnish and install materials to provide 120Vac power to the 66 VAV boxes. This electrical power will be acquired from local mechanical room and electrical rooms.

g) The controls contractor will be required to demo all the pneumatic controls.

h) All equipment to complete the scope of work shall be new, not used, remanufactured, or refurbished.

i) Demo and disposal of all equipment being removed. Barriers will need to be removed and reinstalled if required to remove equipment.

j) When VAV controllers are close to stand alone controllers, connect the communications to the standalone controller.

2) Construction Logistics

a) The work will be scheduled for after hours, after 5:00pm and weekends. Some work will be schedule when the rooms have a planned vacancy. Most of the controls and mechanical work will be in individual rooms, 1 or 2 rooms at a time. Most of the electrical work will be work in the corridors of 1st floor Wing B, C, D, and E. This work will be coordinated with the COR and the management of each wing.

b) VA will complete the Infection Control Risk Assessment (ICRA).

c) Temporary barriers shall be provided by contractors as required by Infection Control.

d) Contractor should limit the number of ceiling tiles removed to not more than 2 at one time, otherwise an open ceiling permit will be required.

e) Contractor work routes will need to be established with the VA.

f) Employees and patients will need adequate access to have means of egress during construction.

g) Schedule shall include a minimum of 7 days for Contractor to remove and reinstall barriers after-hours, install wayfinding and signage, and complete pre-demolition activities for each phase.

All selections of materials shall follow applicable standards and codes described in VA Program Guides & Design Specifications and shall be determined in coordination with Interior Designers at the VA facility. Master Construction Specifications Index, VA Construction Standards Index, VA Standards Index, and Criteria are available in the Technical Information Library (TIL): http://www.cfm.va.gov/til/.
