MIA South Terminal Expansion

TYLin provided plumbing and fire protection systems and airside and landside civil engineering design and construction phase services for the South Terminal Expansion Program at Miami International Airport (MIA) in Miami, Florida.

The program was the first major terminal expansion at MIA since the airport was built in the 1950s.  

Designed to enhance travelers’ experience, the 1.7-million-square-foot South Terminal helps transport 25% of MIA's passengers and serves 20 domestic and international carriers. The multi-level terminal includes the new Concourse J with 15 gates and a renovated Concourse H with 13 gates.  

Landside civil work included the planning and design of curbside roadways and the new South Bus Station, an 18-position facility to serve buses from the Port of Miami. TYLin analyzed the civil design criteria and utilized computer-generated bus movements to ensure adequate pavement area was available for bus maneuvering.  

TYLin’s airside civil work included new aircraft parking aprons, full utility design to service the terminal building, and a unique grading condition for a depressed lower level of the baggage make-up area. 


  • All site work was coordinated with three adjacent projects (terminal, airside, landside roadways) that were part of the overall South Terminal Program. 
  • The design for the South Bus Station included the preparation of an early package for an interim bus station, which was utilized during the terminal building construction. 
  • Landside roadway design included a traffic calming circle for vehicles exiting the airport from the terminal area and adjacent parking structure. 
  • Utility work involved demolition of existing service lines and creation of two replacement drainage lines that had to continue beneath the building between massive foundations.
