Frank Bigelis focuses his practice on construction law. His representations include owners, contractors, subcontractors 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 all standard forms of contract (AIA, DBIA, EJCDC, AGC and FiDIC) as well as customized contracts. A significant portion of his experience has been in government contracts and he has prosecuted claims before the various Boards of Contract Appeals as well as bid protests before the GAO.

Mr. Bigelis' background uniquely suits him to the practice of construction law. Prior to law school, Mr. Bigelis 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.

Since 2006, Mr. Bigelis has been named every year as a Georgia “Rising Star” for Construction Litigation by SuperLawyers magazine. While in law school, he earned a Certificate of Specialization in Environmental Law. Mr. Bigelis speaks French.
