Route 27/244 Interchange

Arlington, Virginia

Quinn provided Quality Assurance (QA) services on this approximately $50 million interchange project in Arlington, Virginia.  This project included the replacement of the Washington Boulevard bridge over Columbia Pike that was built in the 1940s by the War Department as part of the Pentagon Roadway Network.  The new bridge has many architectural and aesthetic features including: decorative pylons in each corner, haunched steel fascia girders with a two-tone paint scheme to mimic the previous arch, a relief pattern incorporated into the vertical outer surfaces, a concrete block pattern on retaining and abutment walls, and medallions with images reflecting the historical significance of Freedmen’s Village for which the bridge will be named.  In addition to the bridge, several ramps were reconfigured to improve access, an existing box culvert that conveyed Long Branch through the center of the interchange was replaced, and a sidewalk and a shared use path were constructed.

Quinn responsibilities on this project included providing all of the QA oversight and testing as well as monitoring the Quality Control (QC) program for compliance with the project specific QA/QC plan and the Virginia Department of Transportation (VDOT) Minimum Requirements for Quality Assurance and Quality Control on Design-Build and Public-Private Transportation Act Projects.  In order to provide this oversight, Quinn assigned a Quality Assurance Manager (QAM) who scheduled and chaired all activity preparatory meetings and who also approved all contractor pay applications.  The Quinn QAM, a professional civil engineer, was supported on site by a team of QA/QC inspectors and technicians as well as two independent offsite testing laboratories.
