KZA was retained to address the most pressing short-term issues at Erik Nielsen Whitehorse International Airport (ENWIA) while maintaining a long-term outlook on building upgrades. Due to its age, ENWIA predated many of the current standard barrier-free requirements in terms of floor-to-floor access and washroom design; elevators were also under-sized. Inadequate ventilation systems as well as non-hygienic washroom fixtures and accessories continually dogged the day-to-day function of the main washroom facilities.

Specific upgrades included renovating the Check-in Area washrooms; increasing the size of the Passenger Screening Area; increasing efficiency of Main Hold Room seating and upgrading the finishes; increasing the number of washrooms in the Main Hold Room; and fitting out the second floor shelled space in the International Wing. With the additional washrooms, the airport now conforms to current National Building Code requirements for washroom capacity and also allows for hands-free operation throughout.

As a value-added suggestion, the new roof of the Main Hold Room washrooms provides an open-concept passenger lounge adjacent to the restaurant at the Mezzanine Level. Providing additional passenger amenities helps promote earlier arrival times.
