This project involved the design and construction of a 23.1-mile extension of the existing 103-mile long WMATA rail system. Upon completion, Dulles Metrorail will provide high-quality, high-capacity transit service in the Dulles Corridor. New Metrorail service in the corridor will result in travel time savings between the corridor and downtown D.C., expand the […]
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.

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.

This design-build project includes the construction of the western and eastern termini of the route for the streetcar, the overhead catenary that will deliver power to the streetcars, and the Car Barn at Benning Road-26th Street. The first segment of the project includes laying out the track, utilities, retaining walls, and other associated site work. The second segment of the project includes the construction of Car Barn building and maintenance yard.
DMY has been working on this project providing Quality Control construction materials testing and special inspection services which include field and laboratory testing for soil and aggregate, concrete and grout sampling and testing, and inspection of the bridge deck repair and drilled shafts for pole foundations. DMY implemented its web-based electronic management and report delivery system – DMY Manager® to efficiently manage the project data.
Additionally, DMY prepared and is currently implementing a two level vibration monitoring program on this project for eleven (11) specified facilities along the project alignment.
