11.05.2024 Project: VLSB 26-0011

Scope Of Work:

This is a project with the goal of replacing the chillers and boiler at building 825.

No design is required for this project. Only material submittals are required.

Material can be ordered once material submittals are approved by the Government. The material submission and approval process is estimated to take 3 weeks (21 calendar days).

General Requirements:

• Before any demolition occurs, the contractor shall measure the maximum chilled water flow through each air handler that will be affected by all chiller installs. The measured flow rate shall be recorded and submitted to the government.

• After each chiller installation is complete the contractor shall measure the chilled water flow through each air handler that was affected by the chiller installation. The measured flow rate shall be submitted to the government for approval.

• The contractor shall modify each concrete pad to accommodate the new chillers.

• The contractor shall install the necessary controls to connect the new chillers, boiler, and all pumps into the existing DDC controls.

• The Base Defense Operations Center (BDOC) cannot operate without heating or cooling; therefore, the chiller demolition shall be planned at best to not interfere with the facilities and a temporary heating or cooling shall be provided for the BDOC.

• The contractor shall insulate and wrap all new piping to meet current standards and the Shaw Design Guides.

• The contractor shall provide a factory start up by a manufacturer approved technician.
