Weld County Human Services Building B HVAC Upgrade

Weld County is seeking bids for a comprehensive HVAC upgrade project for the Human Services Building B located at 315 N 11th Avenue in Greeley, Colorado. The procurement is a lump sum competitive bid (Solicitation #B2500092) for removing and replacing existing HVAC and control systems, which includes seven rooftop units (RTUs), exhaust fans, VAV boxes with electric reheat, and associated building controls. The project requires phased work in a fully occupied building, with most installations to occur outside normal business hours. A mandatory pre-bid conference is scheduled for July 11, 2025, at 10:00 am, with bids due on July 29, 2025, by 10:00 am. Key deliverables include complete system replacement using Trane Precedent rooftop units, updating the building automation system with new DDC controls, and comprehensive commissioning of the new systems. Contractors must provide detailed documentation including O&M manuals, as-built drawings, warranty documentation, and conduct formal staff training. Evaluation criteria are not explicitly detailed, but contractors will need to demonstrate technical capability, compliance with specifications, and provide a comprehensive fixed-price proposal.

The solicitation does not specify specific set-aside designations or restrictions for disadvantaged enterprises. Bids over $50,000 will require 100% payment and performance bonds, and contractors must meet specific insurance requirements, including workers' compensation, commercial general liability, and automobile liability coverage. The project will be funded through Weld County's budget, and the county is a tax-exempt entity. No Davis-Bacon or Buy American requirements are specified. The structural analysis indicates that the existing roof structure can support the new RTUs without primary reinforcement, with unit weights ranging from 1,561 to 2,909 pounds. While a specific budget range is not disclosed, the comprehensive nature of the HVAC upgrade suggests a significant investment in modernizing the county's infrastructure. The anticipated contract execution date is September 1, 2025, with the expectation of improving the building's energy efficiency and HVAC performance while maintaining operational continuity.
