The key portion of this contract dealt with the reconstruction of the keel section of Runway 7L-25R at Los Angeles International Airport, but it also included the construction of Taxiway B17 and the relocation of the northern runway hold bar. Having to contend with the old existing runway was difficult since a variety of materials had to be removed and either disposed of or packaged for reinstallation. This included: airfield lighting cable, centerline and runway status lights as well as taxiway edge fixtures and guidance signs. Installations of lighting infrastructure and fixtures included: 12 LED signs, approximately 529 centerline and 24 elevated edge lights, in addition to 46 taxiway and 16 runway guidance lights, more than 126,000 LF of 5kV cable, 22,400 LF of 600V ground wire and 14,400 LF of conduit.
