Fairfax County Parkway

Fairfax County, Virginia

KCI provide construction management and engineering services for the $141 million VDOT Fairfax County Parkway design-build project located between U.S. Route 1 and Route 7. The project limits stretch from Franconia Springfield Parkway to I-95, and from Backlick Road to Boudinot Drive, for a total of 9.7 miles of new roadway construction. This section of the Parkway was managed by the Federal Highway Administration (FHWA) with funds provided by the Commonwealth of Virginia. This four-phase project consisted of a four-lane, divided, limited-access highway with numerous interchanges and a total of seven bridge structures, including one 420-foot span steel girder bridge with cast-in-place concrete deck over Accotink Creek.

Fairfax-County-Parkway-Night-ConstructionThe first three phases of the project (I, II and IV) were constructed at a total cost of $112 million. This portion of the project corridor begins at Rolling Road (Route 638)/Franconia-Springfield Parkway and proceeds southeast on a new alignment, ending just west of Fullerton Road. A majority of the roadway is located on the western and southern portions of the Fort Belvoir Engineer Proving Ground (EPG). These phases of the project also included the relocation of a portion of Rolling Road, with an interchange at EPG Access Road and the construction of six new bridges. Phase III of the Parkway was a stand-alone, $29 million VDOT design-build project from Franconia Springfield Parkway to Fort Belvoir (north area) to Rolling Road. Phase III consisted of a 5.1-mile, six-lane divided highway with a bridge spanning over the Parkway connecting old Rolling Road with the newly relocated section. Phase III also widened “Ramp D” to two lanes from eastbound Fairfax County Parkway.

Additional scope of work items involved in the four phases of the Parkway extension included a multi-purpose trail, sound barrier walls, MSE retaining walls, storm water improvements, traffic signalization, landscaping, park-and-ride vehicle parking lots and street lighting. The work also included the installation of five tri-chord overhead signs with spans ranging from 63 feet to 154 feet, four cantilever signs with arm lengths spanning from 31 feet to 45 feet, and the relocation of an existing overhead sign spanning 124 feet. Additionally, this overhead sign work included installation on newly modified median barrier and 3-foot-diameter drilled shafts installed at depths up to 20 feet.

KCI’s construction management and inspection work in all phases included supervising the contractor and monitoring work progress to ensure compliance with contract documents, and pre- and on-going construction meetings; and maintaining project documentation including daily reports representing sequence of the project, the equipment used, changes to original schedule, weather conditions, traffic control, etc. Our resident inspectors prepared weekly project and traffic reports one week in advance and forwarded to all stakeholders. The team also handled project document records, including invoices, payroll information and status meeting minutes.
