This file is an excerpt from the 2022 California Mechanical Code, Chapter 11, provided as an attachment to support a Request for Proposal issued by the County of Sacramento for comprehensive design and construction administration services at the Sacramento County Rio Cosumnes Correctional Center (RCCC). The project requires the replacement of twenty packaged gas-electric rooftop HVAC units at Buildings 555 and 570 with individual rooftop chilled water and hot water air handlers paired with a new grade-level chilled water and heating hot water heat pump plant. The design must comply 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, and will result in an all-electric system. 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 must complete design within a six-month timeframe and provide design milestones at 100% Design Development, 50% Construction Documents, and 95% Construction Documents, followed by construction administration through project completion and closeout services.

Cost proposals must be segmented 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. Equipment cost estimates 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. 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 does not identify explicit set-aside designations for disadvantaged enterprises; no incumbent vendors or current contractors are identified. 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. 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.
