Request for Proposal - RCCC - Buildings 555 & 570 - Replace HVAC Units with Chilled Water-Hot Water System, CC-080079-00

The County of Sacramento is soliciting a Request for Proposal (RFP #94844) for comprehensive design and construction administration services to replace twenty packaged gas-electric rooftop HVAC units at the Sacramento County Rio Cosumnes Correctional Center (RCCC) Buildings 555 and 570. The procurement encompasses full design services and construction administration to implement a new all-electric chilled water and hot water heat pump system that complies with Chapter 11 of the 2025 California Mechanical Code, which prohibits high-probability direct expansion air conditioning systems in I-3 occupancies such as correctional facilities. The scope includes replacement of rooftop HVAC units with individual air handlers paired with a centralized grade-level heat pump plant, extension of electrical infrastructure from the existing south utility yard, site modifications, controls integration into the campus HVAC network, and connection to an existing chiller at Building 448. Deliverables include multiple design milestones (100% Design Development, 50% Construction Documents, and 95% Construction Documents), cost estimates, permitting documentation, construction administration through project completion, and closeout services. Cost proposals must be broken into five distinct categories: Design Development, Construction Documents with permitting, Bidding (time and material), Construction Administration (time and material), and Closeout services, with proposers required to provide estimated hours by labor level and hourly rate sheets. Evaluation criteria weight qualifications and experience at 50 percent, proposal quality compliance at 15 percent, cost at 20 percent, availability at 5 percent, and references at 10 percent. The RFP was released on March 23, 2026, with a non-mandatory pre-proposal meeting scheduled for April 8, 2026; questions must be submitted by April 15, 2026 at 5:00 p.m.; and proposals are due electronically by April 30, 2026 at 2:00 p.m. The selected consultant team must complete design within a six-month timeframe and attend County-led bidder conferences throughout the project lifecycle.

The RFP does not identify explicit set-aside designations for disadvantaged enterprises or restrictions limiting organizational types from responding. Team members requiring on-site access at the correctional facility must pass a local background check and comply with strict security procedures established by the Sacramento County Sheriff's Department, including completion of a Security Background Investigation Form at least five business days prior to site entry and mandatory PREA Compliance Training. No incumbent vendors or current contractors are identified in the procurement documents; however, the County has provided a reference project design document consisting of 95% construction documents previously abandoned by the prior consultant, which serves as technical guidance for the forthcoming design phase and includes electrical pathway information and existing utility coordination details. The selected consultant must execute the County's standard consulting agreement and maintain comprehensive insurance coverage including general liability of $2,000,000 per occurrence and professional liability or errors and omissions insurance of $2,000,000 per claim and aggregate. Equipment cost estimates derived from the feasibility study indicate Option 2B (the County's selected approach) at approximately $1,275,000 for core mechanical components, excluding labor, installation materials, contractor markups, and inflation costs; however, specific contract award values or total project budgets are not explicitly stated in the RFP documentation, with final compensation to be established through the executed consulting agreement with a defined maximum total payment amount.
