MIA Concourse H Concrete Apron and Hydrant Fuel Repair and Modification

This project entailed Concrete Apron Modification and Jet Fuel Hydrant Line Leak Repairs at the Miami International Airport (MIA) Terminal, Concourse H. As part of the project, CEI prepared a Maintenance of Traffic Plan (MOT), prepared Dewatering Plan and Dewatering Permit, sampled monitoring well to determine potential groundwater contamination, removed several 20’ by 20’ concrete apron slabs, excavated soil and exposed the jet fuel hydrant line and performed additional helium testing to pin-point exact location of leak. Additionally, we excavated down to uncover the jet fuel hydrant line. A combination of mechanical excavation and hand digging to avoid damage to any potential existing utilities. Poured, placed and finished 16” thick 715 psi concrete in 20’ x 20’ area, saw-cut joints and filled with ½” diameter backer rod and fuel resistant sealant.
