Current Projects

The New Frederick Douglass Memorial Bridge and Suitland Parkway / I-295 Interchange Project was a landmark Washington, D.C. infrastructure initiative that replaced a critical 70-year-old bridge across the Anacostia River and reconstructed the adjacent interchange to improve a major regional traffic corridor. The modern structure enhanced traffic flow, expanded pedestrian and bicycle access, and strengthened long-term resilience for the District's transportation network. Dulles Engineering provided quality control management, construction materials testing, geotechnical services, and environmental compliance oversight throughout the project, ensuring the safety and durability of construction near the sensitive Anacostia River corridor.

The Boundary Channel Drive at I-395 Interchange Project was a vital infrastructure improvement at the gateway between Arlington, VA and Washington, D.C., enhancing access, safety, and traffic flow at a high-volume interchange through reconfigured ramps, new roundabouts, roadway widening, and improved bike and pedestrian connectivity. The completed interchange now provides safer, more efficient multimodal access to major commuter and defense corridors, including the Pentagon, Crystal City, and Rosslyn. Dulles Engineering provided quality control management, materials testing and inspections, geotechnical support, and environmental oversight throughout the construction lifecycle.

The Transform I-66 Outside the Beltway (OTB) Project was one of the largest transportation undertakings in Northern Virginia, spanning 22.5 miles from I-495 (Capital Beltway) to Gainesville with new express lanes, expanded transit options, upgraded interchanges, and improved multimodal connectivity. The project enhanced regional mobility, reduced congestion, and expanded commuter options across the corridor. Dulles Engineering served as a key partner alongside design-build contractor FAM and VDOT, providing quality control management, construction materials testing and inspections, geotechnical evaluations, and environmental monitoring across various phases of construction.

The Northstar Boulevard Phase 1 Project constructed approximately 7,500 feet of new four-lane, median-divided arterial roadway in a fast-growing Loudoun County corridor, with turn lanes at U.S. Route 50, Dulles West Boulevard, and Arcola Mills Drive. Dulles Engineering provided quality control, materials testing, and JMF preparation for Full Depth Reclamation (FDR) on the $90 million project.

The Dulles International Airport Access Highway Rehabilitation Project modernized the primary highway serving Washington Dulles International Airport, restoring its structural integrity and extending its service life for the Metropolitan Washington Airports Authority (MWAA). Dulles Engineering provided quality control management, materials testing, erosion and sediment control inspection, and JMF preparation throughout the project.

The IAD E-Line Sanitary Sewer System Improvements Project at Washington Dulles International Airport delivered 4,900 linear feet of new 36-inch PVC sanitary sewer and 3,800 linear feet of rehabilitation for the Metropolitan Washington Airports Authority (MWAA). Dulles Engineering provided engineering and geotechnical services, including subsurface investigation, excavation support and trench protection design, and utility protection SOPs.

The Dulles Metrorail Project — the extension of Metrorail's Silver Line — is one of the largest transit expansions in the Washington, D.C. region's history, delivered for the Metropolitan Washington Airports Authority (MWAA) through a design-build approach. The project extended rail service across Northern Virginia in two phases, ultimately connecting Washington Dulles International Airport and eastern Loudoun County directly to the regional Metrorail network for the first time. Dulles Engineering provided quality control services and specialized testing throughout both phases of construction, supporting the safety, durability, and code compliance of one of the region's most significant infrastructure investments. 

The Route 1 Widening Project from Marys Way to Featherstone Road expanded capacity, improved traffic flow, and enhanced pedestrian access along a key corridor in Prince William County, Virginia. Dulles Engineering performed Quality Control testing services throughout construction, with certified technicians conducting field testing for concrete, asphalt, and soils to ensure compliance with VDOT specifications. Through timely, accurate QC reporting, DE supported the project's progress and the delivery of a safer, more efficient transportation corridor.

The Route 28 Widening Project is a major transportation improvement designed to reduce congestion and enhance mobility along one of Northern Virginia's most heavily traveled corridors, widening Route 28 from four to six lanes, upgrading intersections, and adding pedestrian and bicycle infrastructure. Dulles Engineering provided Quality Control testing services during construction, including field testing of concrete, asphalt, and soils. Our team ensured all materials met VDOT specifications and maintained detailed QC documentation to support project compliance and timely delivery.

The Balls Ford Road Interchange Project in Prince William County, Virginia, was designed to improve traffic flow, reduce congestion, and enhance safety at one of the region's key east-west corridors — replacing the existing at-grade intersection with a grade-separated interchange, widening Balls Ford Road, and constructing shared-use paths for pedestrians and cyclists. Dulles Engineering provided Quality Control testing services, including field testing of concrete, asphalt, and soils to verify compliance with VDOT specifications, and played a critical role in maintaining quality standards through accurate, reliable QC reporting.

The Malcolm X Interchange at I-295 Project in Washington, D.C. is a key infrastructure improvement enhancing traffic safety and mobility at a heavily traveled urban interchange, involving ramp realignments, new roadway construction, signal upgrades, and improved pedestrian and bicycle access. Dulles Engineering provided Quality Control testing services, including on-site testing of concrete, asphalt, and soils to ensure materials met required standards. Our QC team supported the project with timely, accurate testing data throughout all phases of the work.

The Turner-Fairbank Highway Research Center (TFHRC), operated by the Federal Highway Administration in McLean, Virginia, is a premier facility for transportation research and innovation. Dulles Engineering was engaged to provide Quality Control Management (QCM) services for ongoing infrastructure upgrades and facility improvements across the research campus. Our team oversaw quality procedures across construction activities, coordinated inspections, ensured adherence to federal and project-specific standards, managed all QC documentation, and conducted field reviews — working closely with stakeholders to address quality issues in real time and support timely, compliant delivery.
