Contractors are not authorized to modify real property, including but not limited to: cutting, the roof, altering structural components, electrical conduit replacement, or plumbing modifications beyond equipment disconnection and reconnection at provided service points.

The contractor may replace electrical disconnects and conduit between existing service points and the unit as required to support the installation. However, no modifications to building electrical infrastructure, wall penetrations, core drilling, or real property alterations are authorized under this contract. Any such needs must be identified and coordinated with the VA for separate handling.

Minor penetrations and resealing necessary to complete installation of the AHU and chiller are permitted, provided that no structural modifications to the facility are made. The contractor is responsible for restoring any affected areas to a weather-tight and code-compliant condition. All penetrations must be coordinated with VA Engineering, and work shall not void any existing roofing or system warranties.

Any alterations to the facility structure for installation (e.g., roof modifications) will be performed by the VA or a separately contracted source. Contractors shall notify the VA of such needs on their quotes when submitted.

All services must be performed in accordance with the stated Statement of Work. Questions or assumptions about construction activities should be directed to the Contracting Officer.
