“Rather than installing a traditional single culvert of large diameter RCP, we installed multiple culverts of smaller RCP side-by-side to avoid the fiber optics while still meeting stormwater specifications. Taking this unique approach required a variety of RCP sizes, so it was invaluable to have Rinker Materials specially-produce gasketed Class 5 RCP locally to keep the project on schedule even with the disruption of Hurricane Dorian.”
With no culvert deeper than five feet, the Taxiway A stormwater management system features triple culverts of 36” RCP, triple culverts of 30” RCP, quintuple culverts of 24” RCP and more than 36,400 linear feet of under-drain installed across 12 work areas. Primarily funded by an FFA grant, the $30 million Taxiway A – Phase I was successfully completed despite 70 mile per hour winds and more than 10 inches of rain delivered by Hurricane Dorian.
“PSI was tasked to install the stormwater system per FAA requirements and on strict schedule,” said Breck Dunne, Director of Airport Development for Horry County. “Their knowledge and workmanship proved to be an asset to the construction team.”
