Burns & McDonnell provided airfield electrical design and construction phase services for the rehabilitation of the 8L-26R medium-intensity edge lighting system and replacement of all wind cones. The project included removal and replacement of all 5-KV cabling for the runway edge lighting system, including homeruns back to the vault; removal and replacement of light fixtures (MIRLs and MITHLs); demolition of existing wind cones and installation of new LED wind cones; and removal and replacement of runway pavement sensors. During a review of the existing conditions, it was determined that the existing wind cones were in the wrong place, requiring additional coordination to site them properly. Installation of LED-type wind cones allowed power to come from the edge lighting circuits using isolation transformers instead of the inefficient power adaptors in place previously.
