VHB Honored with ACEC/MW EEA Honor Award
March 1, 2010

Vanasse Hangen Brustlin, Inc. (VHB) was recently awarded an American Council of Engineering Companies of Metropolitan Washington (ACEC/MW) Engineering Excellence Honor Award for the firm’s work on the Route 50 Traffic Calming Improvements Design-Build project. The ACEC annual Engineering Excellence Awards (EEA) competition recognizes engineering firms for projects that demonstrate a high degree of innovation, achievement and value.

VHB, Lane Construction, and state and local officials celebrated the completion of four new roundabouts at Gilberts Corner in Loudoun County at a ribbon cutting ceremony on November 30, 2009. The $15.8 million project improves traffic flow and safety at the intersection of Routes 50 and 15.

VHB, teamed with Lane Construction, was tapped by VDOT to design and build the 1.2 mile Gilberts Corner section of Route 50 which included construction of four roundabouts in the area of the Route 50 and Route 15 intersection and construction of a new roadway between Route 50 and Route 15. The four roundabouts and connector road were completed six weeks ahead of schedule and within budget.

As the design lead, VHB designed the roadway based on a preliminary concept plan developed by VDOT. Substantial alterations were made to the original concept plan that provided both operational and safety enhancements. “The Gilberts Corner roundabouts are now the model for future VDOT roundabout traffic calming projects,” says VHB’s Director of Design-Build Delivery, Greg Lassiter.

Additionally, VHB developed an innovative construction sequencing process that provided for the safe and efficient passage through the area during peak capacity conditions. Extensive public outreach and careful and well-signed interim roadways made the enhancements more effective and safe. “The VHB off-center design and creative detours used for constructing the roundabouts were critical to managing the morning and evening rush hour traffic headed towards the Chantilly and Dulles Airport area,” stated VDOT Project Manager for the Route 50 Traffic Calming Projects, Kenny Lee Robinson.

The firm was also responsible for acquiring all related environmental permits and for providing right of way acquisition design services, as well as utility relocation design services, construction phase design services, and structural services for permanent structures.
