EBA Engineering Receives Two ACEC/MW Merit Awards for DC Metro Area Projects

The Edmonston Avenue Bridge Renovation and Hershey’s Mill Supplemental Aeration projects have both received Merit Awards in the American Council of Engineering Companies of Metropolitan Washington (ACEC/MW) 2019-2020 Engineering Excellence Awards competition. EBA’s Rizwan Siddiqi, PE accepted the awards at a gala on December 4, 2019, in Arlington, Virginia.

ACEC’s annual Engineering Excellence Awards competition recognizes engineering firms for projects that demonstrate an exceptional degree of innovation, complexity, achievement, and value.

“Both of these complex projects offered innovative solutions to improve our clients’ facilities while saving taxpayer money,” said EBA President and CEO Rizwan Siddiqi, PE.

Edmonston Avenue Bridge Renovation

In 2009, a routine inspection revealed that the three-span bridge carrying Edmonston Avenue over WMATA and CSX tracks in Rockville, Maryland, was visually deteriorating. A follow-up inspection confirmed extensive damage to almost every major element of the bridge and the water main pipe it housed.

EBA helped the City of Rockville rehabilitate the bridge to a stronger, more durable, and more attractive structure, extending the life of the existing structure by approximately 25 years. Other improvements included a new architectural metal railing and upgrades to the commemorative plaque dedicating the bridge to U.S. Army Corporal John C. Brown, the first Maryland soldier killed in action in Korea in 1950.

At the conclusion of this project, every portion of the bridge had received much-needed repairs and aesthetic improvements.

Hershey’s Mill Supplemental Aeration

To help solve complex aeration challenges at three wastewater lagoons in Hershey’s Mill, Pennsylvania, EBA teamed with The Environmental Company to install an innovative venturi aeration system.

The venturi process resolved aeration problems for the facility—providing almost three times the aeration capacity while using significantly less power—and is now being used as a supplemental aeration process 365 days a year.

The system also had to meet noise limitations, since residences are located near the wastewater lagoons. The process has proven to be quiet, low maintenance, low energy, and cost effective.
