HJAIA – Plane Train Extension

Clark/Atkinson/Technique is designing and constructing a 700 foot tunnel extension of the existing Plane Train automated people mover system at the Hartsfield-Jackson Atlanta International Airport. Phase 1 includes extensive shifts to the existing traffic lanes for taxis and shuttles (West Curb Improvements). Phase 2 of the project includes tunneling work, as well as changes to elevators and escalator locations within the airport to optimize passenger flow. The tunnel extension goes beneath the existing terminal, MARTA, and SkyTrain systems. 

LONG utilized two survey field crews for the Plane Train project. One 3-person field crew was utilized to provide survey control for lidar scanning work inside of the existing plane train boarding level, AGTS level, apron level and mezzanine level. Survey control was established on the surface and transferred to the tunnel levels through escalators. In order to get control points into the ‘donut’ area, an area completely surrounded by existing airport buildings, the survey crew setup on the roof of the building so that they could obtain a line of sight to both the west parking lot and the ‘donut’ area. Once control was established, topographic surveys were completed in the donut and west parking lot. 

LONG also provided Subsurface Utility Engineering (SUE) services that included designating, marking and surveying utilities, using Ground Penetrating Radar (GPR), and providing test holes in the donut area and West Curb Shuttle Parking Area.
