RMTC was prime consultant for this project involving apron improvements at Gates 6-13 at the busiest airport in the State of Hawaii.  A pavement study was performed to determine if full depth reconstruction or patching would be required.  The entire concrete slab from asphalt concrete to the building was evaluated (approximately 6.59 acres).  It was determined that the existing Portland concrete cement (PCC) pavement was to be replaced with new PCC pavement and pavement markings.  RMTC performed a topographic survey and prepared cost estimates, construction drawings, specifications, and NPDES permit application.
