J--GATE-TROUBLESHOOT & REPAIR HVAC-BLDG 26

Amendment / Modification

This amendment (0002) to solicitation 140P4526Q0010, effective February 27, 2026, provides responses to vendor questions and clarifies certain aspects of the solicitation.

Key changes and clarifications include:

• Scope of Work (SOW) Revisions: The revised SOW now covers additional condenser units and updated requirements for testing and repairing all line sets on each floor.

• Insulation: The revised SOW will state that all piping must be left insulated. If existing piping is usable, it can be reused; otherwise, new insulation must be installed. While the park made minimal repairs that may have removed insulation, the need to insulate those pipes will be included without a separate line item.

• Valves and Fittings: The SOW mentions potential valve replacements, but no specific valves are currently identified as needing replacement. The general statement that the contractor is responsible for diagnosis and troubleshooting of the entire building's HVAC systems covers the evaluation of fittings, including those that may have been installed with "pro press" fittings.

• Access and Obstructions: The Park Service will move any items that obstruct contractor access to work areas, such as files and papers in areas where brazing is to occur.

• Chase Removal: The chase running from the basement to the second floor is not expected to be removed for the investigation work.

• Statement of Work (SOW) regarding condenser units, line sets, insulation, and valve/fitting replacements.

• The proposal due date remains unchanged: March 11, 2026, at 2:00 PM ED.
