This is Addendum #4 to a project manual for the State of California Department of Parks and Recreation Statewide Program Support Center (SPSC) Auxiliary HVAC Control System Upgrade, issued on November 18, 2025. The addendum removes two line items from the original scope of work: the requirement to install and configure a new Carrier I-Vu server (as the Department currently possesses a Carrier I-CU server from a previous HVAC controls project) and the provision and installation of one new Carrier i-Vu controller for control of one existing dehumidification unit. These removals represent modifications to the original project specifications detailed in Section 231000 of the Project Manual. Bidders are required to acknowledge receipt of this addendum by signing and returning the acknowledgement form with their bid documents.

The addendum reflects cost-reduction measures by utilizing existing equipment on site rather than procuring new hardware. This modification is consistent with the broader project scope, which includes upgrading HVAC control systems at the McClellan Facility with an engineer's estimate of $80,000 and a contract term of 730 calendar days from notice to proceed. The mandatory job showing was scheduled for November 13, 2025, with a question submission deadline of November 21, 2025 at 2:00 p.m. The project requires a C-20 contractor license and includes DVBE participation goals with a 6% minimum waived but with applicable incentives, as well as a 5% small business preference for certified small businesses.
