Chicago Midway International Airport, Security Checkpoint Expansion


With an increasing number of passengers passing through Chicago’s Midway Airport, the airport needed to expand its security operations. The 80,000 sq ft expansion over Cicero Avenue creates new interior space, while also serving as a bridge connecting the terminal’s landside and airside. As part of the expansion, the terminal also gets a new airside gateway and retail spaces to enhance the traveler’s experience. SGH consulted on the building enclosure design for the project.

SGH consulted on the exterior enclosure design for the expansion. Highlights of our work include the following:

  • Reviewing the proposed enclosure design concept and recommending ways to improve performance and constructability
  • Developing details for the new curtain wall and integrating it with the existing enclosure and an access catwalk supported on outriggers that extend through the curtain
  • Consulting on the design and fire performance for a new metal panel soffit over the roadway
  • Assisting with the design and developing details for a new long span roof with a curtain wall clerestory with custom glass fiber-reinforced concrete mullion enclosures
