The project focuses on replacing outdated air handling equipment on the fourth floor, including coils, fans, duct plenums, and the full HVAC controls system. The work is structured to remove and replace components in sections, allowing equipment transfer via existing stairwells or the building core elevator, thereby avoiding the need for crane rental.

The estimated construction cost is $4,150,000. Key administrative requirements include mandatory pre-bid participation, electronic bid submission through the Sacramento County Electronic Bidding Portal, bid guarantees, licensing prerequisites, bonds, labor compliance with prevailing wage laws, and adherence to County Standard Construction Specifications revised in November 2024. Contract administration and execution are governed by detailed special provisions incorporating County construction standards, subcontractor management, bid instructions, insurance requirements, and quality control procedures. The contract mandates testing, inspection, and acceptance at the project site, including stringent asbestos monitoring with clearance criteria. Completion deliverables include accurate as-built drawings, testing and balancing reports, operation and maintenance manuals, and certified payroll documentation. Liquidated damages are quantified at $2,298 per day for construction delays affecting labor and supervision costs. Furthermore, the contract integrates Federal Highway Administration required provisions for nondiscrimination, labor standards including Davis-Bacon compliance, and project-specific environmental controls such as packaging and labeling of asbestos waste according to OSHA, EPA, and DOT regulations. Contractors are subject to Title VI civil rights assurances, ensuring compliance with federal anti-discrimination laws throughout project performance. The work must conform to outlined technical specifications, including mechanical, architectural, fire safety, and electrical system standards, and incorporate approved submittals aligned with the proposed schedule and milestones leading to final acceptance by authorities having jurisdiction.
