Clark’s expertise in delivering exceptional aviation work is taking form at the George Bush Intercontinental Airport (IAH) Terminal B Transformation project for United Airlines in Houston as they expand the 525,000-square-foot central processor. 

In January, Clark successfully deactivated the existing 250,000-square-foot Terminal B processor through a meticulously planned overnight operation. This transition involved a year of substantial preparation to ensure a seamless experience for the airport's travelers and staff.

Prior to deactivation, the team executed 13 enabling projects to relocate existing Terminal B tenants and operations throughout the airport campus. Among the most complex projects: relocating the Houston Police Department’s Airport-IAH Division to a new 25-trailer compound; repositioning the 40-year-old underground Subway train controllers; and building a new production kitchen for airport food vendor SSP America to service ten restaurants and three first-class lounges. These efforts were completed without any disruption to airport safety, food service, or train operations.

The deactivation was completed in a single overnight shift, with all services resuming as planned the following morning. Clear wayfinding signage, shuttles, and extensive communication, including updated ride-sharing apps and the United app to reflect new instructions and locations, smoothed the journey for passengers, airline crews, and staff.

Travelers are now directed to Terminal C for ticketing, security, and gate arrivals. A newly constructed pedestrian tunnel allows passengers to safely navigate through the center of the jobsite from the above-ground SkyWay train station.  

The success of the enabling work and transition of airport services marks a critical milestone on the path to delivering an exceptional new processor to United in 2026.
