Installation Procedure

During the installation, all work shall be coordinated with the on-site Contracting Officer's Representative (COR). A project schedule with anticipated installation and cutover dates shall be submitted to the on-site COR.

The Contractor shall locate and clearly mark any and all existing underground; utilities, power and communication cables, before performing soil borings and beginning any excavation procedures. The Contractor shall coordinate with the on-site COR for the exact location of the new foundation, underground conduits, conduit markers, and hand-holes/manholes.

Any shutdown of the utility power or communication services to any FAA facility will be coordinated with the on-site COR. All facility shutdowns shall be requested by the Contractor 48 hours before the desired shutdown.

There are existing power service feeds, telecommunication cables and FAA field equipment within buried underground conduits and cables. Extreme care must be taken during the excavation process so these cables are not severed or affected. Any disconnection or separation of these cables will result in an inoperable facility that will have a direct effect on air traffic. The Contractor will be fully responsible for the immediate repair and cost of any severed or damaged cables during this contract administration.

The Contractor is advised that current FAA facilities are fully operational and any unscheduled interruptions may cause aircraft accidents and loss of life. The facilities shall remain operational throughout the entire contract unless a shutdown is scheduled.

1-1.3 Intent of Specifications. - This specification identifies all labor, materials, supplies and equipment to perform the work required to modernize the facility. All work performed and all materials and equipment used shall be subject to the approval of the COR. This shall include, but not be limited to, testing, inspection, scheduling, reporting, and submittals.
