EDI was selected in a Joint Venture with Ardmore Associates, LLC to provide Construction Inspection and Quality Assurance testing for improvements to the interchange of I-94 (Bishop Ford Expressway) and Stoney Island Avenue in Chicago. The interchange connects a major north-south expressway with a major arterial roadway in an area with high volumes of truck traffic associated with a large commercial area.
Ardmore/EDI provided construction surveys, staking, inspection, quality assurance testing and reporting, measurement, computation and documentation of quantities for construction work performed by McHugh Construction. The project was needed because the existing bridges within the interchange were deteriorating and in need of major rehabilitation including redecking, widening and substructure repair or complete removal and replacement.
The project included seven bridges, several of which were long curved girder bridges requiring special attention. Maintenance of traffic was a unique challenge. Weekend lane closures and complete ramp closures were necessary for proper construction sequencing required in the Plans and Specifications.
