Current Projects

The New Frederick Douglass Memorial Bridge and Suitland Parkway / I-295 Interchange Project is a landmark infrastructure initiative in Washington, D.C., aimed at replacing a critical aging bridge and improving a major regional traffic corridor. Dulles Engineering provided comprehensive Quality Control Management, Construction Materials Testing, Geotechnical Services, and Environmental Compliance Oversight throughout the duration of the project.

Our role was as Quality Control in ensuring the safety, durability, and compliance of all construction activities through rigorous inspections, detailed field testing, and continuous monitoring. The project involved advanced coordination near sensitive waterways and urban areas, demanding a high level of technical precision and environmental responsibility.

The new bridge and interchange now offer enhanced traffic flow, pedestrian and bicycle access, and long-term resilience. Dulles Engineering is proud to have supported this transformative project that connects communities and supports the future of D.C.'s transportation infrastructure.

The Transform I-66 Outside the Beltway (OTB) Project is one of the largest and most impactful transportation infrastructure undertakings in Northern Virginia. Spanning 22.5 miles from I-495 (Capital Beltway) to Gainesville, this project delivers new express lanes, expanded transit options, upgraded interchanges, and improved multimodal connectivity across the corridor. Dulles Engineering served as a key partner by providing Quality Control Management, Construction Materials Testing & Inspections, Geotechnical Evaluations, and Environmental Monitoring throughout various phases of construction.

Our team worked closely with the design-build contractor FAM and VDOT to ensure all work met or exceeded project specifications, safety standards, and environmental regulations. From bridge and pavement inspections to earthwork compaction testing and stormwater compliance, we played a vital role in supporting efficient and high-quality project delivery.

By enhancing regional mobility, reducing congestion, and improving commuter options, the Transform I-66 OTB Project sets a new standard for integrated, sustainable highway infrastructure—one that Dulles Engineering is proud to have supported.

The Boundary Channel Drive at I-395 Interchange Project is a vital infrastructure improvement located at the gateway between Arlington, VA, and Washington, D.C. This project focused on enhancing access, safety, and traffic flow at a high-volume interchange by reconfiguring ramps, adding new roundabouts, widening roadways, improving bike and pedestrian connectivity, and upgrading drainage infrastructure. Dulles Engineering provided comprehensive Quality Control Management, Materials Testing and Inspections, Geotechnical Support, and Environmental Oversight throughout the construction lifecycle.

Our team conducted daily inspections, coordinated testing for asphalt, concrete, and soils, and ensured compliance with VDOT specifications. We also monitored erosion and sediment control measures near the environmentally sensitive areas of the Potomac River and adjacent wetlands.

Through our commitment to accuracy, safety, and quality, Dulles Engineering helped deliver a resilient and efficient interchange that now provides safer multimodal access to major commuter and defense corridors, including the Pentagon, Crystal City, and Rosslyn.

 The Route 1 Widening Project from Marys Way to Featherstone Road aimed to expand capacity, improve traffic flow, and enhance pedestrian access along a key corridor in Prince William County, Virginia. Dulles Engineering was responsible for performing Quality Control testing throughout the construction phase. Our certified technicians conducted field testing for concrete, asphalt, and soils to ensure compliance with VDOT specifications. Through timely and accurate QC reporting, we supported the project’s progress and contributed to the delivery of a safer and more efficient transportation corridor. 

The Route 28 Widening Project is a major transportation improvement initiative designed to reduce congestion and enhance mobility along one of Northern Virginia’s most heavily traveled corridors. The project involves 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, is designed to improve traffic flow, reduce congestion, and enhance safety at one of the region’s key east-west corridors. The project includes 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. Our team played a critical role in maintaining quality standards and supporting timely construction progress through accurate and reliable QC reporting. 

 The Malcolm X Interchange at I-295 Project in Washington, D.C., is a key infrastructure improvement designed to enhance traffic safety and mobility at a heavily traveled urban interchange. The project involves 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 by delivering timely and accurate testing data, helping maintain construction quality and compliance 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 within the research campus. Our team oversaw quality procedures across construction activities, coordinated inspections, and ensured adherence to federal and project-specific standards. We managed all QC documentation, conducted field reviews, and worked closely with project stakeholders to address quality issues in real time. Our proactive QCM approach helped maintain high construction standards and supported the timely, compliant delivery of research infrastructure enhancements.
