With its primary focus on United States Military work, ACC Construction Company quickly expanded from Georgia into the southeast (South Carolina, North Carolina, Louisiana, Tennessee and Kentucky) with current projects stretching throughout the United States and Internationally. ACC has completed over $1.3 billion in construction projects for clients such as the U. S. Army Corp of Engineers, the Department of Homeland Security, the U. S.

A fourth generation of McKnight’s have come into the workforce; Mason McKnight IV, Vice President, Matthew McKnight, Vice President, and Marshall McKnight, Vice President / CFO returned after college to work for ACC.
