What the government is buying
NAVFAC Mid-Atlantic is soliciting bids to replace an HVAC system and components at facility CAD593, a military installation in the Mid-Atlantic region. This is a construction project focused on heating, ventilation, and air conditioning work on an existing building or facility. HVAC replacements at military facilities typically involve removing aging equipment, installing new energy-efficient systems, updating ductwork, and ensuring compliance with current energy and environmental standards.
The work falls under NAICS 236220, which covers commercial and institutional building construction. This classification indicates the project is substantial enough to be considered building construction rather than routine maintenance or repair services.

Who can bid
This opportunity is reserved exclusively for small businesses certified as small under NAICS 236220's size standard. To qualify, your business must meet the Small Business Administration's size threshold for this NAICS code, which is based on average annual receipts over three years. You do not need a specific socioeconomic certification (such as 8(a), HUBZone, SDVOSB, or WOSB) to compete—any eligible small business may bid.
If you plan to subcontract portions of the work, be prepared to document your small business subcontracting plan if required. NAVFAC typically expects prime contractors to meet project labor and safety requirements common to military construction. See the solicitation for any bonding requirements, past performance criteria, or specialized HVAC experience the government expects.
How to put together a competitive bid
Understand the scope before pricing. HVAC replacements at military facilities often involve working in occupied buildings with operational constraints, potential asbestos or lead-based paint abatement, and compliance with Unified Facilities Criteria (UFC) and ASHRAE standards. Review the drawings and specifications in the solicitation carefully—assumptions about equipment types, refrigerants, or control systems can create significant cost variances.
Factor in security and access requirements. CAD593 likely requires contractor personnel to hold appropriate security clearances or at least complete background checks for installation access. Badge procedures, escort requirements, and restricted work hours are common at Navy facilities and affect labor costs and scheduling.
Demonstrate relevant past performance. NAVFAC evaluates construction experience on similar military or institutional HVAC projects. Prepare summaries of completed projects with comparable scope, dollar value, and complexity. Include customer contact information for verification.
Address quality control, safety, and scheduling in your technical proposal. NAVFAC construction contracts typically require a formal quality control plan and compliance with EM 385-1-1 safety standards. Show how you will minimize disruption to base operations during equipment changeout.
For your price proposal, ensure you account for prevailing wage requirements under the Davis-Bacon Act, material lead times for specialized HVAC equipment, and any disposal costs for the existing system.
