RMF Marks Project Milestone at West Gates Expansion, Charleston International Airport (CHS)

RMF Engineering recently reached an important project milestone with the topping out of the West Gates Expansion at Charleston International Airport (CHS) in North Charleston, South Carolina, led by Charleston Regional Aviation Authority (CRAA).

The $105-million, two-level west concourse adds 40,000 square feet of passenger space and four new gates to the airport, including space for retail, dining, passenger hold rooms, restrooms, and international arrivals. RMF’s role in the project includes full mechanical, electrical, and plumbing (MEP) engineering services through all phases of design.

The project is part of the airport’s Terminal Area Plan and Validation Report, which identified the need for expanded facilities to accommodate growing aircraft and passenger demand. As a result, the facility is being designed to deliver efficient, reliable, and cost-effective infrastructure to support Charleston International Airport’s continued growth. Completion is expected by the end of 2026.
