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.

DC Water Main Process Train

DC Water recently completed work at the Main Process Train of the Blue Plains Advanced Wastewater Treatment Plant. The design-build project included the rehabilitation of four solids blending tanks, installation of 12 new strain screens in a new screenings building, a pre-dewatering building that houses 10 pre-dewatering centrifuges, four trains of Cambri’s thermal hydrolysis treatment (THP), a digester building including pumping and cooling heat exchangers, and the construction of four 3.8 gallon digesters and associated odor control equipment.

 

DMY provided construction materials testing and special inspection services. The work included field and laboratory testing for soil and aggregate, concrete and grout sampling testing, and inspection of the installation of 477 auger-cast-piles and 144 drilled piers. This was the first project where DMY implemented DMY Manager®, its web-based electronic management and report system. This system allowed DMY engineers and field staff to efficiently manage the project and effectively control the quality of the deliverables.
