David S. Gallacher

Of Counsel

David's professional experience involves a wide variety of litigation, administrative and corporate counseling issues related to federal procurement laws. His experience includes complex litigation in federal court under the qui tam provisions of the False Claims Act, claims disputes before the Boards of Contract Appeals, and bid protest actions at the U.S. Court of Federal Claims and Government Accountability Office.

David regularly counsels companies—both domestic and foreign, large and small—on issues relating to compliance with government procurement regulations including, among other things, subcontract administration, supply chain management, country of origin requirements under the Buy American Act and Build America/Buy America, state and local infrastructure spending, export controls, merger and acquisition due diligence, cost accounting, suspension and debarment, and small business regulatory requirements. He also regularly assists clients with internal compliance reviews and internal investigations, helping assure companies that they are in full compliance with the law.

David is also an active speaker, writing on emerging issues and hosting webinars to help provide a practical understanding of very complex regulations.
