Four small Maryland firms stand to split $15 million NASA plans to spend during the next five years on architecture and engineering services at the Goddard Space Flight Center in Greenbelt, Md., the Wallops Flight Facility in Wallops, Va., and several smaller Goddard facilities, such as remote tracking stations.

The indefinite-delivery, indefinite-quantity contracts announced Sept. 13 went to Global Engineering Solutions Inc. of Rockville; Cho Benn Holback & Associates Inc. and EBL Engineers LLC of Baltimore; and Waldon Studio Architects and Planners of Columbia.

NASA said the companies will provide engineering and special studies, preliminary engineering reports, final design and follow-on construction services for nontechnical facilities, including restoration and office modifications.
