SANITARY SEWER REPLACEMENT AND APRON REHABILITATION

Project Details

CLIENT
Kenton County Airport Board

LOCATION
Kentucky, Cincinnati/Northern Kentucky International Airport

 

The Cincinnati/Northern Kentucky International Airport (CVG) Terminal 3 Consolidation/Concourse A Reactivation program was initiated to consolidate operations after an airline hub vacated Concourse A. Accelerated design and construction schedules were employed to meet the 11-month consolidation/reactivation deadline.

Woolpert worked with CVG staff to identify a new routing to correct the flat, inefficient sanitary outfall. The team located the more favorably sloped run mid-panel across the apron, resulting in the removal/replacement of only one row of panels for the installation of the new sanitary line. Additionally, Woolpert technicians provided subsurface utility locating services to determine the actual location and depth of an existing 10-inch jet fuel line crossed by the new sanitary outfall.

The aging pavement surrounding the concourse exhibited numerous weather-related surface distresses that Woolpert inventoried during a detailed visual inspection of the apron. Woolpert then developed a rehabilitation plan that included partial-depth patching, partial-panel replacement and isolated full-panel replacement to restore the apron pavement surface. Woolpert utilized FAA concrete specifications for the pavement rehabilitation, enhancing them with techniques and materials suitable for repair and rehabilitation.

Woolpert staff used a vacuum excavation truck to accurately locate the underground fuel line crossing the new sanitary outfall.
