The focus of Frank Bigelis’ practice has been on construction law and government contracts.

His representation has included owners, developers, contractors, subcontractors, architects and engineers on worldwide projects with varied delivery mechanisms, including design-build, EPC, CM at Risk and the traditional design-bid-build. Mr. Bigelis has extensive experience in drafting and risk-management under all standard forms of contract (AIA, DBIA, EJCDC, AGC and FiDIC) as well as customized contracts. Mr. Bigelis has also focused on government contracts, (in areas including construction, services, supply and intellectual property) and the Federal Acquisition Regulations – he has prosecuted claims before the various Boards of Contract Appeals as well as bid protests before the GAO and the Court of Federal Claims.

Representative of his work, Mr. Bigelis represents the owner on the largest public infrastructure in the United States, the Central Artery Project in Boston, MA, also known as the “Big Dig.” The project includes the defense against hundreds of million dollars in impact, inefficiency, acceleration and other claims in the Courts, Dispute Resolution Boards, and arbitration. He has also represented the design-build contractor on a major remediation and mixed-use project for the Meadowlands in New Jersey, the design-build-operate-maintain contractor on the Tren Urbano rail project in San Juan, Puerto Rico, and contractors on numerous power plants and hospitals across the country.

His government contract work includes representing contractors federal courthouses, air force and army bases, Army Corps of Engineer Projects, and prosecuting claims or bid protests. Mr. Bigelis has provided counsel on compliance with the False Claims Act, Business Ethics and Internal Control System programs, as well as the minutiae of the FAR.

Mr. Bigelis' “on the ground” experience uniquely suits him to his practice. Prior to law school, he worked for a nationally recognized consultant engineering and construction management firm. During that time, he was responsible for the design and construction of water treatment plants and water supply systems. As both a senior design engineer and project/resident engineer on large construction projects around the country, his responsibilities included coordination of the entire construction process from conceptualization and design, through submittal coordination, construction and final completion. His experience includes supervising the world's largest horizontal directional drill, as of 1997, and numerous infrastructure projects in excess of $500 million.

Mr. Bigelis has been named a Georgia “Rising Star” for Construction Litigation by Super Lawyers magazine over multiple years. While in law school, he also earned a Certificate of Specialization in Environmental Law. Mr. Bigelis speaks French.
