Lotte Duty Free occupies more than 32,000 square feet of space at the Guam International Airport Authority concourse (departure) level. The Main Store retail concession areas and associated airport improvements included 12 each “white box” spaces for future “Brand Stores.” These white boxes were completed as part of the Phase Two milestone in March of 2014.

The overall project included a “Chamorro Cultural Center” opposite the entry to the concourse area, which included a 4,500-gallon saltwater aquarium, a Chamorro Hut, Latte Stones and artists' renditions of local historic landmarks. Upgrades to the existing concourse passenger terminal areas included TSA security areas, construction of food court common and seating areas, and renovation of 10 restrooms. The project was performed over a nine-month program to implement “phased area completion” as part of a rapid transition from the previous retailer to opening Lotte retail sales areas. Black Construction Corporation was successful in meeting each phase requirement in order to stock and open all sales areas and begin earning revenue for the client.
