Supply Process Sterilization (SPS) HVAC Corrections Project # 523-09-156

SUPPLEMENT “A”

Additional Requirements of Architect/Engineer Services:

1) The Architect-Engineer (A/E) shall provide all space programs, temporary facilities, schematic design, design development, construction documents, construction administration services, calculations, equipment selections and cost estimates to provide Supply Process Sterilization HVAC Corrections for the Jamaica Plain Supply Process Sterilization operation at the VA Boston Health Care System, Jamaica Plain Campus.

The SPS floor area is shown on drawing AE104, Second Level Floor Plan, SPD Process Design/HVAC Upgrade Building 1, as designed by SMRT and bound by “limit of work”.

2) The SPS area is currently served via the following: 15-ton rooftop condenser unit; AHU- 1 (1540CFM); and AHU-2 (2670CFM). Exhaust is provided via several fans: EF-1 (1540CFM); EF-2 (1110CFM); and 2-EF-8 (11,000CFM).

3) In addition to the upgrades determined via site visits, investigation of existing documents and user meetings, this project shall reroute ductwork that was provided under project 523-07-139, SPS Process/HVAC Upgrades. Project 523-07-139 provided a 15,000 CFM station air handler to provide partial HVAC for the SPS area. The air handler was not tied into the SPS area due to the long duct distances and high ambient temperatures at the ductwork plenum. However, this equipment can assist with the pressurization with lobby areas that are adjacent to SPS. The A/E shall design reroute of ductwork to re-establish pressurization and HVAC control for the basement lobby, first floor lobby and second floor lobby of building 1. Provide selective demolition, variable air volume boxes, building automation control, pressure control, duct distribution, fire protection and replacement of finishes.

4) On site visits to define the details of the project scope of work meeting the goals of the

Veterans Affairs' (VA) project team, and presentation of preliminary layout plans with proposed alternatives.

5) Electronic drawings shall be developed utilitizing most up to date VA version of

AutoCad. Each electronic drawing file shall be identified with the drawing number and drawing title.

6) Specifications shall be developed utilizing most up to date VA version of MS Word.

Electronic Specification files shall be identified with the specfication number and specification section title. Individual MS Word specification section files as well as a consolidated MS Word file of all specification sections is required. In addition, a pdf consolidated file of all specifications sections is required.

7) Cost Estimates shall be developed utilizing most up to date VA version of MS Excel.

8) All computer-generated files shall be IBM compatible and furnished on high quality CD-
