Major renovation transforms Alaska's key transportation hub while maintaining 24/7 operation

ANC needed a major overhaul of Concourses A and B as well as the baggage claim and ticket lobbies. The project included a major seismic retrofit; a new (Transportation Security Administration) TSA screening space; HVAC, plumbing, electrical and telecommunications system upgrades; new baggage handling systems; building security systems; and interior design updates. The building's age also required the replacement of glazing, thermal envelope and roofing systems. 

The original building was made up of small, compartmentalized spaces which required a fresh approach to improving traffic flow, natural light and access to amenities. The new design also needed to align with that of Concourse C, which had already been updated. 

A key aspect of the project was ensuring the older facility complied with updated TSA luggage screening standards. This involved creating space for TSA staff and equipment, accommodating new technologies (including those that hadn’t been acquired yet) and ensuring that secure and sterile spaces couldn’t be breached.

RIM Architects, now part of GHD, led integrated design services working alongside aviation consultant HNTB and program manager Parsons Brinckerhoff (now WSP). Our design strategy focused on creating contiguous, easily maintained spaces while maintaining strict security for non-public areas, washing the interior of public areas with natural daylight, and highlighting amenities like restrooms and checkpoints with color and materials. 

We selected new finishes that align with Concourse C in quality, maintainability and aesthetic presentation. Natural wood wall systems and porcelain tile wainscoting were incorporated for protection and to introduce warmer hues, serving as way-finding components visible and distinct from a distance. At passenger portals, natural stone pylons accent the walls and are topped with decorative soffits lit with "alpenglow" indirect lighting to call attention to specific instructional signage. 

To improve passenger flow, we transformed the old food court into a centralized screening area and relocated the main mechanical plant. Our team worked in close partnership with TSA to understand methods of screening, types of equipment (including assets they may acquire in the future) and determine line location and clearances at various stages. We designed a special trench and overhead hoist to service the equipment and provide access to the space without slowing down the through-put of the scanners.

The comprehensive modernization achieved multiple critical objectives while maintaining full operations. The consolidated passenger screening area provides enhanced security while preventing breaches between public and secured spaces. Enhanced natural lighting, improved circulation and modernized concession spaces create an elevated passenger experience. The seamless integration of Alaska-inspired finishes - including wood, stone and innovative lighting - delivers a sophisticated yet distinctly regional aesthetic. 

By focusing on programming, rightsizing and ensuring all elements work together harmoniously, our team delivered an improved passenger experience and future-proofed security infrastructure while maintaining 24/7 operations throughout construction.
