McKenney’s partnered with JE Dunn on a project at Hartsfield-Jackson Atlanta International Airport in preparation for Delta’s new baggage handling system (BHS). The scope included relocating existing MEP infrastructure—ductwork, mechanical piping, and plumbing systems—to clear a path for the new baggage handling conveyor system, in addition to installing a new chilled water air handling unit, all while ensuring uninterrupted airport operations. 

THE CHALLENGE

Relocating complex infrastructure at one of the world’s busiest airports came with major logistical challenges. All work took place at night, requiring coordinated staffing and seamless handoffs between day and night crews. McKenney’s navigated a multi-party approval process involving the City of Atlanta, Delta Airlines, and third-party consultants. Every task required detailed Method of Procedure (MOP) documentation, submitted and reviewed weeks in advance. Even with approval, work could still be delayed or denied due to changes in airport operations. A key technical hurdle was moving critical chilled water piping for the entire domestic terminal without interrupting air delivery to security checkpoints and public areas.

THE SOLUTION

McKenney’s overcame these challenges with thorough preconstruction planning and tight coordination, including BIM modeling. The team performed detailed field investigations, worked closely with maintenance teams, and led walkthroughs with stakeholders to finalize workable solutions. For the chilled water system, McKenney’s engineered and installed a temporary bypass to maintain service during pipe rerouting. 

THE RESULTS

With major mechanical work already completed, McKenney’s has delivered 80% of the project, and the remaining scope—primarily in Concourse C—is on track for completion in 2025. Our team’s precise planning and clear communication ensured uninterrupted passenger comfort and airport operations, and the client’s satisfaction has positioned McKenney’s for continued partnership on future airport projects.
