Airport Expansion and Renovation Improvements
Hartsfield-Jackson Atlanta International Airport
Atlanta, GA

Hartsfield-Jackson is the busiest airport in the world with 207 gates and over 102 million passengers annually. Atlanta embarked on a 20-year master plan for a $6 billion expansion and renovation of the airport.

KAI is providing MEP/FP design services for fire and life safety realignment for the entire airport’s terminal and concourse space totaling 6,800,000 SF.

KAI’s services include studying existing emergency exit lighting and making recommendations where the existing emergency egress lighting does not meet current code, providing designs to remove existing MEP/FP items from exit stairs where they items do not serve the stairs, relocating existing MEP items located within the new paths of egress, and providing design for new exit signs and the removal of signs that are no longer needed.

The scope also includes testing and reporting on existing fire alarm voice intelligibility and volume, removing and replacing up to 1,400 existing doors, relocating existing door controls to new and existing IDF rooms, fire alarm design and sprinkler design in the tunnel system.

KAI is also providing electrical engineering for the new 70,642 SF Welcome Plaza on the west side of the airport, a large multipurpose space beneath a dappled green glass canopy that can be utilized for special events and press conferences and will have kiosks, displays and informative exhibits. The plaza provides access to trains, ground transportation and the new airport hotel.
