The Airfield Lighting and Signage Upgrades consisted of the installation of over 800 elevated LED taxiway edge lights and over 135 LED guidance signs across the entire airfield. In addition to the new LED lights and LED signs installed, the project upgraded electrical circuit and homerun cable in existing ducts systems, added LED runway guard lights, and replaced 10 old constant current regulators with 10 new constant current regulators.
One of the major design considerations included several different options for new airfield guidance sign foundations to resolve the airport’s issue of the sign foundations tilting due to settlement or heavy mower traffic.
As part of the project design, Benesch formulated a phasing plan which included 13 different phases, and/or work areas, in order to comply with FAA and Lincoln Airport safety requirement and still allow aircraft to utilize various areas of the airport with active edge lighting systems. Temporary wiring and circuit combining was implemented. In order to combine circuits, for phasing purposes, Benesch verified existing regulators had the capacity to handle the circuit loads of the lights that were active during the particular phases.
