Airport Runway Reconstruction
KLJ was selected to perform engineering services on the Madison Municipal Airport in Madison, SD. At the time, the airport was serving heavier aircraft than the pavement was designed to support. KLJ solicited a soils testing firm to core existing airport pavement to determine thickness and condition, as well as examine underlying soils.
Solution: Due to existing conditions, KLJ determined runway 15-33 pavement needed to be reconstructed. KLJ designed pavement sections for both asphalt concrete and Portland Cement Concrete (PCC) pavement.
To minimize airport closure, KLJ spent significant time developing construction phasing. To provide a smooth transition across the reconstructed runway 15-33, KLJ redesigned the intersection at Runway 3-21 and Runway 15-33. KLJ efforts provided significant savings for the airport at more than $600,000 under estimated cost.
