The Maryland Board of Public Works has approved a $60M contract for Whiting Turner Contracting Company to expand Baltimore/Washington International (BWI) Thurgood Marshall Airport’s Concourse E.

The scope of the contract will include the construction of a three-level, 6,500m2 extension to Concourse E that will support growing international airline service.

The expansion project will add six new airline gates — two full-service gates with airline hold rooms and four arrival-only gates.

It will also include a new electrical substation, added restroom facilities, new mechanical and electrical support spaces, an extension of the sterile corridor system to connect with the federal inspection station, and space for additional baggage make-up operations.

Governor of Maryland Larry Hogan said: “BWI continues to set records and this expansion highlights the continued success of our airport, as well as Maryland’s flourishing economy.

“This expansion will create new job opportunities for hardworking Marylanders, while bringing greater ease and efficiency to international travel, tourism, and trade.”

The new airline gates are set to be complete by mid-2018.
