Phase II, Dulles Metro Rail

The Dulles Corridor Metrorail Project (DCMP) is undertaken by MWAA in partnership with Fairfax and Loudoun Counties, as well as the Commonwealth of Virginia.  Phase 2 of the DCMP starts from the Wiehle-Reston East Station and will extend the Silver Line 11.4 miles west into Loudoun County, VA.   It will include six new stations, Reston Town Center, Herndon, Innovation Center, Washington Dulles International Airport, Route 606, and Route 772 Ashburn. Five of the new stations will be built on ground level.  An aerial station will be constructed at Dulles International Airport.

 

DMY is currently working on this project providing both field and engineering services including geotechnical drilling, rock coring, rock pressuremeter tests and data analysis, borehole logging and field work coordination.  Special challenges include very stringent drilling fluid and siltation control requirements, complex field work coordination with the Design-Builder, MWAA, VDOT and other team members.  DMY, as one of the few geotechnical companies with the expertise of rock pressuremeter testing and data interpretation, successfully performed rock pressuremeter tests in boreholes down to 65 feet deep in challenging geological conditions and obtained valuable data to support the deep foundation design.

Interstate 66 Active Traffic Management

The $38 million project will install an active traffic management system on a 34 miles stretch from I-66 through Arlington, Fairfax and Prince William counties from the Washington, D.C. line to Route 29 in Gainesville.

 

The system will improve safety and incident management and include new sign gantries, shoulder and lane control signs, speed displays, incident and queue detection, and increased traffic camera coverage. Drivers will see the new overhead sign gantries installed between the Beltway and Route 29 in Centreville.

 

DMY is currently working on this project to provide QC inspection and testing services during clearing & grubbing, E&S controls, MOT, subgrade preparation, backfill, asphalt, concrete, and foundations.  DMY has provided a QC Manager, QC Coordinator, and several inspectors to ensure the proper compliance of the work with VDOT requirements.
