Fairfax County Parkway, Phase III

  • Fairfax County Parkway, Phase III

Quinn Consulting Services, Inc. performed Quality Assurance inspection services on this $28 Million project that was advertised by the Federal Highway Administration using funds from the American Recovery and Investment Act. The project limits were from the Franconia-Springfield Parkway (State Route 7900) on the north and Fairfax County Parkway Phases I & II on the south, and ran for approximately .5 miles along existing Rolling Road (State Route 638) and through the western portion of the Engineering Proving Grounds (EPG) at Fort Belvoir. This project was the final segment required to complete the Fairfax County Parkway and included: construction of a six-lane divided, limited access highway; Franconia-Springfield Parkway interchange improvements; a shared use path alongside a portion of Rolling Road; widening the existing ramp onto the Fairfax County Parkway to two lanes; sound barriers along Rolling Road and the widened ramp; stormwater management facilities; and a new bridge (B692) over the Fairfax County Parkway @ Rolling Road.

Quinn provided a licensed professional engineer as Quality Assurance Manager (QAM), QA inspectors, and QA materials technicians as required to complete QA inspection and testing services on the project. The QAM was responsible for overseeing the QA/QC process and for entering laboratory testing results into the FHWA QL Pay System which was specified as the acceptance program for asphalt, aggregate, and concrete payments on the project.
