This Statement of Work (SOW) outlines the Multi-Building HVAC Controls Upgrade project (DDPM262611) at the 136th Airlift Wing, Naval Air Station Joint Reserve Base, Fort Worth, TX. The project's primary goal is to upgrade and integrate HVAC control systems in Buildings 1670 and 1671 with the base’s Niagara DDC infrastructure. Additionally, it addresses failed or end-of-life HVAC components across multiple buildings, including HVUs, VAV boxes, boiler pumps, AHUs, and VFDs, ensuring their integration into the Niagara system. The scope encompasses site surveys, removal of obsolete systems, mechanical, plumbing, and electrical modifications, installation of new components (Distech controllers for Buildings 1670 and 1671), system integration, testing, commissioning, training for government personnel, and comprehensive documentation. The project requires adherence to federal, state, and local codes, including specific UFCs. The SOW is divided into three Contract Line Item Numbers (CLINs): Building 1670 HVAC Control System Upgrade, Building 1671 HVAC Control System Upgrade, and Wing-Wide HVAC Unit Replacements, with a 60-calendar day performance period.

This federal contract amendment (SF 30) modifies solicitation W50S7626QA005, issued by the Texas Air National Guard (TXANG) 136th Airlift Wing in Fort Worth, Texas. The primary purpose of Amendment 0001 is to officially incorporate contractor Requests for Information (RFIs) and the Government's corresponding responses into the solicitation. This is achieved by incorporating the document "RFI Worksheet - HVAC Controls (07.10.2026)" by reference. Additionally, the amendment implements two key changes: - **Proposal Deadline Extension:** The response due date is extended from July 14, 2026, to July 16, 2026. - **Contract Clause Modification:** DFARS Clause 252.236-7001 (Contract Drawings and Specifications) is updated to include the Statement of Work for repairing HVAC controls in Buildings 1670 and 1671, alongside the newly added RFI Worksheet. All other terms, conditions, and provisions of the original solicitation remain unchanged. Offerors must acknowledge receipt of this amendment prior to the specified bid submission deadline to avoid rejection of their proposals.

This Request for Information (RFI) worksheet clarifies requirements for the HVAC Controls Project at the 136th Mission Support Group, solicitation number W50S7626QA005, overseen by Contracting Officer Captain Crabtree. The document addresses key contractor inquiries regarding the project's technical scope. To establish full Niagara platform integration, contractors must include upgrading to the JACE 9000 and replacing legacy controllers with two-way read/write capabilities rather than monitoring-only gateways. Contractors are responsible for creating new graphics matching campus standards only for Buildings 1670 and 1671. Existing BACnet MS/TP trunks and IP infrastructure will be reused, and no additional BACnet cards are required for the existing chillers, which are already integrated. Contractors do not need to replace pump starters with VFDs. For CLIN 0003, pricing must be restricted to the specific HVAC components listed in the Statement of Work (SOW), and the government does not mandate a specific brand for the Building 4175 VFD replacement. While certified Distech dealer status is not required, bidders must demonstrate Niagara Framework and BACnet integration experience and supply all necessary programming licenses and configuration tools. Historical control drawings, schematics, and points lists will be provided post-award. Contractors should not include contingency pricing for unlisted, inoperative legacy field devices, as these will be handled via case-by-case contract modifications. Finally, payment bonds are required for contracts awarded between $35,000 and $150,000.
