Our two latest projects on the East Kellogg corridor included the biggest contract and the most extensive schedule to date. These two projects expanded the expressway from Rock Road to the K-96 interchange. The general improvements were reconstruction and expansion of the Kellogg interchange at I-35 (KTA), new bridge, intersection and frontage roads at Webb Road, expanded intersection, twin overpass bridges and frontage roads at Greenwich and Zelta, frontage roads and bridge to service two-way traffic access at 127th Street and reconstruction of Kellogg bridges over KTA with new toll ramps.
This project required management of safety, scheduling and resources over a six-year timeframe and coordination with three major owners/agencies (KDOT, KTA and City of Wichita) along with numerous engineering partners, subcontractors, suppliers and the traveling public.
Because we were able to coordinate all projects, the overall completion time was 6 months less than originally estimated.
The combined quantities for major materials on the projects included:
- Common Excavation – 1,240,000 cy
- Compacted Fill – 750,000 cy
- Reinforcing Steel – 3,280,000 lbs
- Structural bridge steel – 5,355,000 lbs
- Aggregates – 500,000 tons
- Concrete – 155,000 cy
- Utilities (SWS, WL, SS & Comm.) – 116,000 LF
