If the bidder chooses not to visit the site, he will nevertheless be charged with knowledge of conditions that a reasonable inspection would have disclosed. A site visit date will be set up by the Contracting Officer and the Facility Manager.

Prospective bidders shall contact the C.O. for the date and time.

Work Hours/Coordination – Work must be performed on weekdays between the hours 6:00AM and

5:00PM. The Contractor’s on site representative must meet with the designated FAA COR (in person or via phone) on a daily basis to discuss and review the work proposed for that day, the following work day, and following week. The review must include any special procedures, constraints, impacts to the facility, or schedule requirements involved in completing the work.

Deliveries - The Contractor must be on site to accept all deliveries.

Contractor at no additional cost to the Government. Repairs must be approved by the COR and must match the original. The Contractor must provide all temporary covers, enclosures, etc., required to protect the existing facilities. Prior to beginning work, the Contractor must conduct a walk through and inspection of the site with the designated FAA representative and note the existing conditions and any damage. The inspection must include all areas that will be affected by the performance of this scope of work. Existing damage or defects must be noted and will be the basis for determination of damages caused by the Contractor’s operations. Failure of the Contractor to perform this inspection indicates that all areas are free of damage and defects.

The Contractor must also maintain 24 hour access in and out of the 1 facility gate and must stage the work to assure vehicular traffic access into and out of the facility for site employees.

Work Phasing - The facility must remain accessible and operational throughout the performance of work required by this scope. The Contractor must plan, schedule, sequence, and execute the work in a manner that will minimize disruptions to facility operations. In the event of an emergency or critical operational need, FAA maintenance and emergency response activities must take precedence over the
