body
PROCUREMENT:
The contractor has encountered unforeseen field conditions that have delayed completion of the Oak Meadows WSF portion of the project beyond the current contract scope. As a result, this amendment will provide additional engineering services under Task 800 - Construction Administration to support the extended construction duration through project completion.
The additional services are required to address the replacement of a recently installed air conditioning unit at the Oak Meadows WSF that was damaged during construction. The originally approved air conditioning unit is no longer available from the manufacturer and must be replaced with a different brand. Engineering services will include review of shop drawings for the replacement unit, on-site coordination during installation, observation of testing and startup activities, and support through project closeout to achieve final completion. This project is located in Districts 1 and 6.
