Berkshire SC - VRF Installation - Addenda 1.pdf

This is Addendum #1 to a Request for Proposal issued by the Commonwealth of Massachusetts Executive Office of the Trial Court, Office of Court Management, Facilities Management Department for VRF system installation at the Berkshire Superior Court Clerk's Office in Pittsfield, Massachusetts. The addendum provides clarification regarding the system configuration in response to a vendor question. The project requires installation of a four-zone mini/multi-split heat pump system with one outdoor condenser unit and four indoor heads, where each head operates with individual temperature setpoint control but all heads function in the same heating or cooling mode simultaneously. The bid is identified as BD-27-1107-FREG5-ACCOU-132395, with bids due September 9, 2026, at 12:00 p.m., and a mandatory pre-bid walkthrough scheduled for September 1, 2026, at 10:00 a.m. Project completion is required by April 30, 2027.

This addendum clarifies that the system is not a variable refrigerant flow (VRF) system where individual zones can operate independently in different modes, but rather a four-zone mini/multi-split configuration with synchronized operational mode requirements. Bidders must acknowledge receipt of Addendum #1 on their proposal forms. The clarification addresses a critical system design specification that affects equipment selection, installation methodology, and cost estimation for prospective contractors. Massachusetts prevailing wage requirements apply to all trades involved in the project, and Daikin or Mitsubishi systems are preferred by the agency.
