Overview
Approximately 192,000 passengers and guests pass through Sky Harbor each
day, which has experienced a 32% increase in passengers since 1990.
The number of aircraft landing and departing the airport has also
increased. With more than 526,000 takeoffs and landings in 1997,
Sky Harbor was the world’s highest traffic airport with only
two runways. Safety concerns for the traveling public and to accommodate
growth was the major incentive for adding the third runway, which
is 7,800’ in length.

Details
GARDNER ZEMKE performed all electrical and control work for the construction
of Phoenix Sky Harbor Third Runway Project. Electrical work included
150 miles of cable, 9 miles of fiber optic cable, 203 manholes, 41
miles of ductbank, 1,890 runway/taxiway light fixtures, 2 MALSR systems,
2 PAPI systems, controls to 2 ILS/localizers, 145 runway and taxiway
signs, and a new airfield lighting computer control system for the
control of all lights and signs on the airport. The airfield lights,
signs, and navigational aids are to be controlled through the new
computer system located in four locations and interfaced via fiber
optic cable, level 7 control wiring and wireless backup nets.
The
technical challenges on this project included locating and identification
of hundreds of existing underground utilities, which was accomplished
utilizing an electronic utility locating device and a truck mounted
potholing machine, which utilizes high pressure water and vacuum
in lieu of mechanical
digging equipment. Another challenge was the project phasing and schedule
delays due to conflict in relocation of the Arizona Air National Guard
facilities at the airport. |
