Phase 3 28* $1000

Entire Project 178 $2000

*Once project is re-started, 28 days before the Terminal Concourse Expansion Project is completed.

Work on this contract will be carried out in multiple phases as defined in the phasing plan. The Contractor shall prepare and submit a detailed schedule of proposed activities for review and approval, a minimum of 2 weeks in advance of the Contractor beginning any phase of work. The proposed phasing may be modified by the Airport due to flight operations.

Phase 1 includes mobilization, provide drawings for approval, then drawings are sent to the City of Savannah for permitting. Phase 1 can be extended if there is an unforeseen delay in the permitting process.

Once permits are received, then Phase 2 can begin. Phase 2 will consist of the construction of the lighted walkways.

Phase 2A will need to begin immediately to remark the ramp associated with the new ground boarding gate positions. This phase is to be completed within 10 days.

When the walkways are operationally accepted, contract time will be stopped.

Time will be stopped approximately 2 years to allow for completion of the concourse expansion. If the concourse expansion is not completed after 2 years, then the rental of the walkways will be paid based on a monthly basis.

After substantial completion of the Terminal Concourse Expansion project, then

Phase 3 will begin which will be the demolition of the walkways. The demolition is to be completed in 2 phases. The first phase will be the south side, then the second phase will be the north side of the walkways.

Lighted Low-Profile barricades are required and will be provided by the Airport.

Contractor must maintain an automated mechanical sweeper to ensure that all debris is swept clean of the active taxiway pavement at all times.
