In 2020, Ceco completed work on the Consolidated Rental Car (ConRAC) facility at John Glenn Columbus International Airport in Columbus, Ohio. The project involved constructing a three-level rental center garage, which joins the quick turnaround station by a set of helix ramps and bridges. The more than 1.2 million-square-foot facility houses more than 2,600 vehicles. Ceco provided deck formwork services for 465,000 square feet of post-tensioned (PT) concrete garage.
The garage’s efficient beam-and-slab structural system allowed the use of Ceco steel beamforms combined with larger steel girder formwork and Ceco’s unique P1 panel system for the PT slab soffits. The large concrete girders, each measuring 48 x 44 inches, required the Ceco team to follow the load redistributions on the shoring through the various PT tensioning sequences until the entire load was finally distributed to the columns. The structural system was a great choice that met many key constructability measures. It’s design allowed Ceco to achieve the project’s schedule safely and with a high degree of reliability.
The ConRAC facility is the first phase of a long-range plan to expand capacity at the airport. Work began August 2019 and the Ceco team topped out June 2020.
