CONTECH Construction Products Inc.’s plate, precast, and truss structures provide answers to a wide range of airport application needs, says the compnay. Contech’s plate and precast structures support runway extensions, enclose drainage ditches, and cross streams. Precast concrete arch taxiway underpasses and bridges can be used to allow fully-loaded 747s to cross over busy airport highways, provide underground tanks for de-icing solution storage, and create baggage tug tunnels. Precast units are easily adjusted for curved alignments and can be set side-by-side for multiple span configurations. The arch-box shape provides an economical, durable structure with enormous load carrying capacity. Truss skywalks can provide pedestrian crossings from terminals to parking.
