MICHAEL E. DEBAKEY VA MEDICAL CENTER

HOUSTON, TEXAS

Project Title: Replace hydronic cooling coils for AHU 19 and AHU 10-1

1. GENERAL:

Contractor shall provide all labor, transportation, materials, tools, and equipment necessary to replace two hydronic coils for AHUs 19 and 10-1 inside Building 100 on the DeBakey VA Medical Center at 2002 Holcombe, Houston, TX 77030.

2. DESCRIPTION OF SERVICES:

a. Two hydronic cooling coils (one for AHU 19 and one for AHU 10-1) are damaged and need replacement in Building 100.

1. AHU 19 is a York Solution XT Indoor Air Handler rated at 11,100 CFM installed in roughly 2016 and is located on the first floor. See Attachments 1 and 2 for information. Contractor should field verify all components.

2. AHU 10-1 is a Trane Performance Climate Changer Air Handler rated at approximately 8500 CFM and is located in the basement. See Attachments 3 for information. Contractor should field verify all components.

3. Both coils shall be replaced with new, functionally equivalent or better, coils. Temporary repairs to both coils have been performed and both AHUs are still operational. The work will need to be scheduled to allow continued operation of the areas served by this AHU. Work requiring the AHU to be shut down will need to be performed outside normal work hours (M-F, 6 AM-6 PM). All phasing will be coordinated with the COR. Consult with the COR for exact items and locations.

b. The contractor will provide all labor, materials, equipment, permits, supervision, and any other services necessary, to complete the following tasks:

1. Remove existing AHU panels, insulation, and any other components necessary to allow removal of the damaged coils.

2. Remove damaged coils (two total cold water coils, one for each AHU) and replace with new coils that meet or exceed the quality, capacity, and capabilities (temperature, pressure, flow, etc.) of the existing coils.

3. The new coils shall have a corrosion resistant coating at least equivalent to an ElectroFin E-Coat or an Epoxy Immersion Coating as shown in Attachment 4. Submit specifications for VA review and approval.

4. Provide any necessary new screws, gaskets, sealants, couplings, etc. to replace the damaged coils. All new equipment and components must be fully functional and work properly with the existing equipment.

5. Test the newly installed components to verify water and air flows, cooling functions, and that no water leaks are present. Demonstrate to the COR that water flows through all new coils without leaks before cabinet panels are reinstalled.

6. After new equipment functionality has been confirmed by the COR, reinstall cabinet panels, gaskets, etc. to bring the AHU back to a functionally sealed condition roughly equivalent to the condition before the panels were removed.

7. Install new insulation on pipes and other locations where the original insulation was removed to allow removal and replacement of the coils. New insulation should be equivalent to the existing in thickness and quality.

8. Perform final functional check to confirm heating and cooling capabilities are restored and no leaks are present.

c. All work shall be accomplished within sixty (60) calendar days from the date designated by the Contracting Officer. The VA would like this work to be accomplished as soon as reasonably possible.

d. After award, but prior to the start of any field work, the contractor shall contact the COR to review proposed methods and schedule for accomplishing the work and to review shut down requirements, hot permits, and VAMC safety requirements. Field work may not commence until these items have been reviewed and approved as detailed below.

e. All new materials and components will be tested (by the contractor at their expense) and be fully functional upon completion of installation.

1. Make all necessary piping connections.

2. Follow manufacturer’s installation instructions.

3. Damage caused by the contractor during this project to any existing surfaces shall be repaired to the original condition at the Contractors expense.

4. Any changes to this SOW shall be authorized and approved only through written correspondence from the CO.
