More than 20 Years Supporting Your Mission

In 1999, two Marine Corps Veterans named Malcolm Gibson and Sean P. Harmon, shared a vision of starting a company that would combine Malcolm’s 30 years in the construction industry with Sean’s expertise in operations and business management.

In recent years, ESA South (ESA) has been enjoying sustainable growth due to its many successful projects and growing list of satisfied clients. Currently we are focused on streamlining operations and expanding our geographical footprint across the U.S. and beyond; including opening new offices around the country and building relationships with large and small businesses alike to help support our goals. We are excited to be moving into the large business category in the near future and look forward to continuing our commitment to providing our clients the outstanding service to which they are accustomed.

ESA has experienced phenomenal growth in recent years contracting projects with a value up to $50M and higher with a bonding capacity of $150M individually and $300M aggregate.

Construction Crew

Our Mission

To deliver the safest, highest quality project in the most efficient manner.


ESA South has professional engineers on staff to meet project requirements featuring any level of design. We further enhance our design-build capabilities by teaming with experienced architecture and engineering firms to offer this project delivery method. 


Construction of Healthcare facilities is unique in that there are additional concerns for patient safety such as Infection Control Risk Assessment (ICRA), Indoor Air Quality (IAQ), Interim Life Safety Planning (ILSM), and noise pollution, etc. 

Disaster Relief

ESA has provided disaster relief services since 2004. We continually maintain a state of readiness and can place boots on the ground within 24 hours. Services include blue roof, debris management, and rapid repair.

I am not sure how you guys pulled this off with two major hurricanes and typical long lead times, but the biggest critical path worry on the plate was the AHUs and Chiller...now ON-SITE. Please let all your subs and team know. You guys are some serious string pullers. Outstanding.
