BWI Airport Terminal Expansion

project summary:

The Terminal A/B Expansion program included the addition of 568,000 square feet of new terminal to consolidate Southwest Airlines operation into a 26-gate facility that would be expandable to 31 gates. Landside improvements included a major expansion to the curbside system and elevated Skywalk system connecting the short term parking garage to the terminal through three overhead pedestrian bridges. Terminal modifications included new vertical circulation elements throughout the terminal complex and renovation of the existing passenger processing areas to increase efficiency and provide a common architectural theme combined Terminal Complex.  Associated airfield improvements consisted of a new dual parallel taxiway system, aircraft terminal apron areas, hydrant fueling system and a centralized deicing pad.  Infrastructure improvements included expansion of the central utility plant, new dual redundant electrical substations, feeders and switchgears, and upgrading of the water, sanitary, and natural gas systems.

ADCI’s principals were responsible for the overall design project management and the design of all airfield improvements.  A major portion of this work included the phasing of airline operations to allow Southwest to continue to successfully grow its operation throughout the program. ADCI’s principals were responsible for phasing all airside work including multiple relocations of gate positions.  Since May of 2006, ADCI has been providing subcontract services to the Maryland Economic Development Corporation (MEDCO) for final closeout of the project.
