The exis�ng facility was constructed in five phases, including 3 separate buildings and two in-fill structures, then a roof over all buildings tying them together. Each building por�on was constructed with its own separate u�li�es. The Government has provided Jacobs with several incomplete As-Built drawings for different phases of construc�on which may be shared.

The Headquarters Building 1002A and Dining Hall 1002C are occupied and will remain opera�onal during renova�on of 1002B.

The standing seam metal roofing is exis�ng. There will be limited re-work of the standing seam metal roofing as required to patch removed and or relocated mechanical and plumbing penetra�ons.

The metal canopy out front and drive thru canopy out back are exis�ng to remain. There is no scope for renova�ng any of the canopies; however, there is scope to repair select areas of damaged and/or deteriorated EIFS fascia associated with the canopy out front.
