Statement of Work

1.0 - Background The Bureau of Reclamation (Reclamation), Upper Colorado Basin Region, Albuquerque Area Office (AAO), is one of the largest area offices in Reclamation, reaching from the Alamosa area of southern Colorado through most of New Mexico and into west Texas. The AAO is responsible for planning, design, and construction of projects in the Brackish Groundwater National Desalination Research Facility (BGNDRF) located in Alamogordo, NM.

BGNDRF was authorized by FY 2004 Energy & Water Appropriations (Sec 210 of PL 108-137) pursuant to the Water Desalination Act (PL 104-298) and explicitly permits up to 100% federal cost-share of facility design, construction, operation, maintenance, repair, and rehabilitation.

The Brackish Groundwater National Desalination Research Facility (BGNDRF) is a federal facility that operates under the United States Department of Interior, Bureau of Reclamation (Reclamation). Established by an Act of Congress, the facility mission is to promote sustainable advanced water treatment research and technology development for inland brackish groundwater sources and, specifically, to conduct research for the development of cost-effective, robust desalination and alternative energy technologies that produce sustainable new supplies of water and power for municipal, industrial, agricultural, and environmental purposes.

BGNDRF is looking to replace its 10-ton split unit that conditions a server room and an electrical supply room. The unit has failed, likely due to a refrigerant leak and equipment age. Equipment shall incorporate EPA approved refrigerants that will extend equipment maintainability. Contractor shall furnish and install all equipment, controls, materials, and perform required testing. In addition, the Contractor’s HVAC professional shall verify sizing and equipment selections to optimize performance and efficiency.

2.0 – Scope BGNDRF has a broken split unit (ACCU-1/AHU-1) that is at the end of its useful life. The ductwork and sensors are original to the building (20 years old). All HVAC systems are controlled using a Trane Tracer® Synchrony program and are connected to the building’s existing fire detection system (HVAC is turned off if fire is detected). BGNDRF does not have a technician on staff that is well-versed in the use of the Trane Tracer® program, however, they can provide historical information.

2.1 – Location and Hours of Operations Reclamation’s facility is located at 500 La Velle Road, Alamogordo, NM 88310.

Reclamation’s standard business hours are Monday through Friday from 7:30 AM to 4:30 PM MST except federal holidays.

2.2 – Site Visit Reclamation plans to hold two site visits for prospective offerors, one on June 25, 2026, at 9 AM Mountain Daylight Time (MDT), and one on July 1, 2026, at 9 AM MDT. Offerors are encouraged to be present to take measurements and view the site conditions. Please reach out to Malynda Cappelle at mcappelle@usbr.gov or (575) 443-6553 to confirm attendance.

Interested bidders should inform the contract specialist on this combined synopsis/solicitation if they plan to attend the site visit. Offerors will be shadowed at all times by a government employee or designated construction inspector.

2.3 – Period of Performance The Government anticipates the contract will be awarded by July 31, 2026, and the work must be completed within 60 days of the award. The anticipated contract dates will be finalized prior to award.

Adjustments to the schedule will be considered if parts availability are an issue or weather will impact quality and safety during the project activities/tasks.

The Contractor shall use good housekeeping practices and cleanup all work areas at completion of each workday. All discarded materials, debris, and trash shall be contained and removed from the project site at a weekly minimum and disposed of according to local requirements. Within 48 hours the Contractor shall remove all equipment and materials not required to meet the requirements of this specification from the construction site.

The Contractor is responsible for the security of all equipment and materials on site. In addition, all material shipments, transportation, and storage are the responsibility of the Contractor. Unless arrangements are made with the BGNDRF Manager to provide access for shipments to be delivered.

All design work and equipment selection shall be in accordance with the Guiding Principles for Sustainable Federal Buildings.

4.1 Removal of existing units

Remove existing HVAC systems in accordance with these specifications, standards, and industry best practices. The following include expected activities:

· HVAC system being removed shall be recycled or disposed of offsite and in accordance with local requirements.

· Remove existing HVAC systems:

· Remove existing forced air accessories that are not required for use with new HVAC system.

· Remove existing HVAC system including capturing refrigerant for approved disposal.

· Disconnect water and drains prior to removal of equipment. If the piping cannot be reused, the piping can be removed.

· If new equipment isn’t immediately installed, install temporary measures to prevent wanted or unauthorized access and mitigate weather damage.

4.2 Installation of new existing units
