Milhouse served as a subconsultant to Jacobs Engineering Group on the Chicago Department of Aviation’s Runway 4L-22R rehabilitation project at Midway International Airport.
The rehabilitation of Runway 4L-22R featured pavement reconstruction and bituminous overlay on one of Midway Airport’s major runways. The project included overlaying the entire runway surface with three inches of bituminous concrete and a two-inch overlay on the shoulders, and then thickening the pavement at the intersection with Runway 13L-31R to mitigate ponding. Work on Runway 4L-22R also included a 200-ft.-long run-up area between Runway 13L and the realigned Taxiway P. In addition, Taxiway P was realigned to accommodate Taxiway Design Group (TDG) 3 aircraft and to provide a perpendicular crossing at Runway 22R. The taxiway realignment required regrading stormwater detention areas on either side of the taxiway to maintain storage volumes. Stormwater detention volumes were determined using XP-SWMM modeling software.
Milhouse was responsible for the design of storm sewers and underdrains, as well as calculations of stormwater detention. Additionally, Milhouse assisted with the development of construction phasing, erosion control, and restoration plans.
