Atlanta has become one of the country’s busiest construction markets, and the firms headquartered here reflect that range — from national data-center and aviation builders to civil-infrastructure giants that have made the metro their US home base.

Atlanta’s construction market
Atlanta’s contractor base sits inside one of the country’s strongest construction economies. Georgia’s construction sector employed roughly 220,900 people as of August 2024, according to Associated General Contractors of America data, and a large share of firms continue to report skilled-labor shortages — a constraint that pushes even the largest builders to plan their workforce more deliberately as data-center, aviation, and infrastructure work competes for the same crews.
