Consider approval of Change Order No. 2, for AIP Project No. 3-40-0062-013, at Davis Field, or take other necessary action. (Mike Stewart)
BACKGROUND:
Electrical junction structure 5 had to be shifted north from the plan location due to a gas line running parallel to the existing east/west pavement along with a fiber optic line. The junction structure had to be placed between the gas line and the fiber optic line without room for adjustment. Shifting the electrical junction structure to this location caused a steep grade from the existing ditch that has been susceptible to erosion in periods of heavy rain. Electrical junction structure 5 has 3 conduits entering the structure from the east and south with 6 5kV cables for the Runway, Taxiway and PAPI homerun circuits. This change will protect the home circuit from erosion and possible damage from future mowing operations. This change increases contact time by 3 working days for Phase 1. (1 day added for earth work, 1 day added for forming and 1 day added for concrete placement)
RECOMMENDED ACTION:
Approve of change order #2-final for AIP project NO. 3-40-0062-013 at Davis Field or take other necessary action.
