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.
