Barbara is recognized as one of the leading construction and government contracts attorneys in the United States with more than 35 years of experience in construction and government contracts law. She has been resoundingly and consistently recognized as being one of the top attorneys in construction law. She is a Fellow in the American College of Construction Lawyers, and a Fellow in the Construction Lawyers Society of America, as well as recognized by Chambers and listed in Best Lawyers in America, Construction Law (2012-2017). Barbara has lectured extensively to clients and various trade associations on a variety of construction law topics. Her expertise and experience is reflected in her comprehensive practice. She is known as an expert on contract terms and conditions for developers and owners, and focuses on contract drafting and negotiation. She also represents owners, contractors and subcontractors in litigation involving scheduling, delays, inefficiencies, changes, differing site conditions, and terminations for default.

In 2006, Barbara hosted the first Women in Construction Conference ("WIC") in Washington, D.C., by women for women in all aspects of the construction industry. Today, in its 12th year, the conference boasts 300 attendees, with an all-day event featuring five panels, a keynote speaker and a Speaker/Sponsor reception the night before the conference. WIC is a non-profit organization with a Board of Directors that has created a WIC Scholarship to the ACE Mentoring Program.

Barbara excels as a trial attorney and as a skilled arbitrator and mediator. She is included on the American Arbitration Association Roster of Arbitrators and Mediators and has completed advanced mediation training with the Center for Dispute Settlement at Judicial Arbitration and Mediation Services, Inc. ("JAMS") and employs uncompromising objectivity in resolving multi-party, complex case disputes where the parties appear to be unyielding.

Representative Experience

In the private sector, Barbara litigates claims on behalf of owners, general contractors and subcontractors in federal and state courts and before arbitral tribunals. She also drafts and negotiates construction contracts for developers and owners. In the public sector, she routinely represents sureties and government contractors in claims against the federal government. Barbara has represented contractors and sureties in performance and payment bond disputes and has represented government contractors in False Claims Act cases. She also represents government contractors in bid protests and claims at the Boards of Contract Appeals and the Court of Federal Claims.

Barbara’s trial accomplishments are substantial. Some of her successes include:

  • Winning the largest jury verdict ever in a commercial case in Jackson County, MS, for a subcontractor on a project that involved the dismantling of a fertilizer-manufacturing facility.
  • Settling a nine-figure claim for alleged defective windows where the plaintiff had already prevailed in one trial and sought to enforce that judgment in 38 other lawsuits.
  • Obtaining a rare summary judgment on the behalf of a plaintiff contractor in a default termination case against a subcontractor.
  • Securing the first and only case in which the court overturned the Navy contracting officer’s non-responsibility determination and directed an award to a contractor.
