T.Y. Lin International was selected by the Illinois Department of Transportation (IDOT) to provide Construction Engineering Services for the repair and reconstruction of I-80/94 (Kingery Expressway Mainline) from Burnham Avenue to US 41 in Indiana. This 1.6-mile (2,580m) segment was part of the overall I-80/I-94 reconstruction project by IDOT. This stretch of roadway carries over 159,000 vehicles daily, with over 30 percent of the volume being trucks.
The Kingery reconstruction project was constructed through a number of different construction contracts. These contracts included the following elements:
- Removal and replacement of the Little Calumet River Bridge, a six-span 590-foot (180m) steel plate girder bridge
- Removal and replacement of overpass structures at Hohman Avenue, a three-span, 193-foot (58.8m) PPC I-beam structure, and Harrison Avenue, a single span, 121-foot (36.8m) steel plate girder structure
- Construction of five retaining walls founded on metal shell piles and spread footings. The walls were up to 22.5 feet (6.85m) in height and utilized form liners to provide an architectural finish.
- Construction of approximately 25,000 feet of a 10-foot-high sound barrier system mounted on drilled shafts and retaining walls
- Construction of continuously reinforced concrete mainline pavement to a new eight-lane cross section with full shoulders
- Construction of a sewer separator system and mainline drainage
- Installation of Intelligent Transportation System components, including traffic volume detectors, weigh-in-motion truck scales, variable message signs, and closed circuit television cameras
Project challenges included the construction of one project that straddles the Illinois-Indiana border with each respective portion built to that State’s standards, requiring knowledge of both the Illinois and Indiana specifications.
TYLI services included: providing construction inspection, contract administration, submittal review, and survey verification; coordinating and monitoring traffic control and roadway maintenance; and supplying Quality Assurance material testing and quantity documentation, all in accordance with IDOT procedural guidelines. Other tasks provided include conducting weekly progress meetings, monitoring the contractor’s schedule, assisting in contract document interpretation, and preparation of correspondence, letters, and authorizations for IDOT review.
Additionally, this project included the opportunity, in conjunction with the IDOT, to participate in a new State of Illinois initiative to provide construction industry jobs to local neighborhood residents. Eighteen trainees over two construction seasons were included in the TYLI project team and received both on-the-job and classroom training for a six-month period in all areas of the inspection and documentation of construction projects.
