Winter constructed 1,950 square feet of a divided retail tenant and bakery concession space in the new Maynard H. Jackson International Terminal at the Hartsfield-Jackson Atlanta International Airport. The retail areas are located above the new International Terminal conveyance system. To avoid collision with the conveyance system, Winter used sonogram before beginning work to identify the location of existing pre-cast tension cables. This uncovered discrepancies between the structural engineer’s plan and the existing utilities. Because the Winter team caught this potential problem early, they were able to relocate 50% of the plumbing, without affecting the schedule or budget, and successfully install the plumbing cores, soda line systems, and floor sinks. Despite the initial challenges, the entire project was completed in less than eight weeks in the fully operational airport environment.
