The Department seeks a turn-key, commercial design and construction/installation solution for a large-scale HVAC modernization/replacement project at a military installation in the Colorado Springs, CO area. Interested firms should be ready to outline their delivery model (in-house or teaming), relevant commercial/mission-critical HVAC experience, SAM registration status, and experience with military or high-security installations. The government also asks about business size, socio-economic certifications, surety bonding or alternative financial protections, Davis-Bacon compliance, and the ability to accept electronic milestone-based payments. Responses would be requested through a streamlined Commercial Solutions Opening (CSO), with a concise 5-page solution brief potentially due in under 30 days. No budget amount is specified in the description.
