This $43.3 million project (total cost) was located at the Interstate 64, exit 91 interchange with Route 285 (Tinkling Spring Road) in Augusta County, Virginia. This project improved the operation of the interchange by increasing the capacity, enhancing operational safety, and addressing existing access management issues on the Route 285 corridor. Improvements on this project included widening the ramps, replacing/widening the Route 285 Bridge and road from a two-lane rural-section to a four-lane urban roadway, to include intersection and signalization. In addition, dual turn-lanes and dual receiving lanes were provided at both I-64 on-ramps and dual left-turn lanes were built at Route 636 to accommodate traffic growth from the nearby hospital complex.
Quinn provided a professional engineer as the Quality Assurance Manager (QAM) and the QA inspection staff responsible for implementation of the project specific QA/QC Plan. The QA/QC Plan was developed to comply with the Virginia Department of Transportation (VDOT) Minimum Requirements for Quality Assurance and Quality Control on Design Build and Public-Private Transportation Act Projects (January 2012) and included project documentation requirements, activity specific inspection checklists, standardized materials testing forms, and procedures for identifying and resolving project execution non-conformance items.
