Airports are increasingly incorporating design features that help manage major fluctuations in security lines.
Jeff Mechlem, Stantec’s airport sector leader, explains how reducing the number of columns and permanent walls in wide-open areas supports the security pipeline. These adaptations allow airports to accommodate changing equipment and technologies, and help with the configuration of queues.
Stantec’s work at Houston’s George Bush Intercontinental Airport (IAH) Terminal Redevelopment and Denver International Airport showcases the ability to make space in central processing areas for security lines to spread out—without impacting bag-drop and check-in counters.
An operational buffer separates each function, allowing lines to extend past their usual footprint. Usually, these buffer zones seamlessly blend into the landside space of the airport, like wide concourses.
While some wait time is inevitable, architecture can drive a more pleasant, stress-relieving experience, says Mechlem.
