Chatham EngineeringFIRM PROFILE

Chatham Engineering’s staff is comprised of 11 professionals who provide mechanical, electrical, plumbing and fire protection engineering services to a wide variety of clients in Georgia, South Carolina and Florida.  We have worked with architects, owners, developers and agencies to provide effective and technically sound design solutions for educational, housing, healthcare, resort, marina, government, industrial, commercial and criminal justice facilities.

Our principals practice their disciplines and are actively involved with the design and management of every project.  They continually stress the importance of understanding current technologies and of maintaining effective quality control procedures.  This emphasis enables our people to achieve a high level of expertise and to deliver superior engineering services.

The engineers of Chatham Engineering always look to design facilities to provide long-term value to our clients. We study life cycle costs, which result in systems that can be constructed to meet budgets, yet can be maintained and operated in an efficient manner. Our firm has professionals that are LEED accredited.

It is the goal of Chatham Engineering to produce appropriate engineering solutions that satisfy the varying needs and requirements of our clients.

Exceptional service to our clients is also one of our guiding principles.  We pledge to perform our work in a professional manner, work as a team with all others on projects, be responsible and responsive and to make all projects a success.
