Newark Liberty Runway 11-29 Rehabilitation
The Port Authority of New York and New Jersey recently led a project to rehabilitate Runway 11-29 at Newark Liberty International Airport, the oldest of the airport's three runways. We were hired to assist with upgrading the runway's electrical systems, duct banks and lighting to meet current FAA requirements.
Because the airport would not be closed for any of the required work, careful coordination was imperative. We worked with airport staff throughout the survey, design, documentation and construction staging processes to ensure minimal interruption to flight service. We spent extensive time studying existing documents to prepare for detailed field reviews and investigations.
Reviews showed that all runway lighting was in need of replacement. Light assemblies comprised of stainless steel base cans were installed along the taxiway and runway proper to better withstand the effects of environmental conditions. Runway edge lights were also upgraded using an alternating configuration powered by two separate circuits, allowing one of the circuits to fail and the runway to remain open.
A new taxiway centerline lighting system was put in, as were touchdown zone lights to assist pilots on their approach. Upgrades were made to Electrical Vault No. 1 as well. In the end, detailed documentation of the design facilitated staging so that construction had minimal effect on the use of the facility.
