ATCS Project Acknowledged by VDOT/VTCA


The VDOT I-95 Bridge Rehabilitation Project in the City of Richmond and Henrico County, Virginia was honored with the VTCA Transportation Engineering Grand Award at a recent VDOT/VTCA Consultant Forum.

The $15 million project, completed in 2014, entailed the replacement of 11 bridges on I-95 northbound and southbound through the City of Richmond. The four-year project covered a seven mile stretch of I-95 between Lombardy Street on the perimeter of downtown Richmond and Upham Brook in Henrico County which borders the City.

Michael Baker International was the prime consultant for this project. ATCS provided Construction Inspection services which included daily field inspection of all contractor work, ensuring that the contractor completed all work adhering to contract specifications. In addition Inspectors were responsible for work zone safety and environmental checklists. Project Controls Support developed and maintained detailed summary construction schedules, as well as reviewed and evaluated contractor baseline, updated schedules and progress tracking submittals.

The ATCS Construction Schedulers developed monthly critical path status reports and schedule performance graphs. They reviewed and tracked change orders, work orders, performed cost/schedule time impact analyses, and responded to contractor claims.



ATCS Selected as Prime on the Salem District I-81 NB Exit 105 Interchange

ATCS is pleased to announce that it was selected as the top ranked firm for negotiations, to provide construction engineering inspection services for the replacement of the Interstate 81 NB Bridge over the New River and the replacement of the Rt. 232 Bridge over I-81, by The Virginia Department of Transportation (VDOT).

This project will replace the I-81 NB Bridge over the New River as well as the Route 232 Bridge at the Exit 105 Interchange which crosses over I-81. Minor improvements will be made to both the I-81 NB off-ramp and on-ramps at this interchange. There will be a variety of drainage improvements along I-81 and many stormwater management facilities will be constructed, not only near the above-mentioned bridges but also at the Rest Areas located on both NB and SB I-81 at mile marker 108. Other work will include utilities, landscaping, guardrail, and permanent signage. This project will be advertised for construction in June of 2016 so inspection work could begin in late fall/early winter of 2016. Construction is expected to run through the end of 2020.

The main portion of work centers around the 1,700-foot long bridge over the New River at the Montgomery/Pulaski County lines. This 70 foot tall bridge is one of the larger structures in Southwest Virginia.




I-95 4th Lane Widening, Fairfax County, Virginia

The I-95 4th Lane Widening project is located in Fairfax and Prince William Counties. The project limits were from Route 123 (Gordon Blvd) to Route 7100 (Fairfax County Parkway). The six (6)-mile widening project adds a fourth general purpose lane in each direction to I-95 at an estimated cost of $86 million. Major Components include 11.2 lane-miles of road construction adjacent to high volume/high speed interstate traffic in very tight working conditions (ADT = 221,000), two (2) bridge widenings involved marine type work, and eight (8) bridge widenings that were of median/complex difficulty. The project also included 16 retaining walls totaling 2.1 linear miles (included RW-3 gravity walls, MSE, and drilled shafts), 2.5 miles of storm pipe installation, and eight (8) sound barriers (both ground and sound mounted).

ATCS performed construction management and inspection services for VDOT’s Northern Virginia District. Project tasks included field inspection for roadway grade and bridge/structures, soil and slope stabilization inspections, documentation, material testing, communications with stakeholders, public outreach, traffic maintenance inspection, and environmental monitoring for over 31 acres of disturbance. ATCS also provided project control services which included document control, CPM schedule reviews for baseline and monthly updates, change management, time impact analysis, cost estimating, and reporting.
