The SR93 project is a Florida Department of Transportation highway improvement project located on I-75 in Hernando County, FL. The project involved milling and resurfacing of the highway, along with infrastructure improvements, including installing 2,208 lineal feet of 8”-48” round reinforced concrete drainage pipe manufactured by County Materials.
The project’s contractor was Middlesex Corporation. Delivery and unloading of the pipe presented them with a specific challenge for this project. Near Brooksville, the highway runs very close to a large body of water. It was necessary to install a most of the concrete drainage pipe in that section. With no room on the shoulder to unload the pipe, a lane closure would be necessary in order to allow County Materials’ trucks to park and be unloaded.
Because this section of highway services heavy commuter traffic, the DOT required it to remain open during daytime hours. As a result, the concrete pipe deliveries were scheduled to take place overnight. An additional complication arose because the contractor’s lane closure crew was only available on this project for five nights. It required a collaborative effort to coordinate the pipe deliveries and unloading in the time allotted.
In all, County Materials delivered 31 truckloads of concrete drainage pipe over the course of five nights. Six to eight truckloads arrived each night. The first trucks began unloading at 9:30 P.M. sharp, shortly after the crew closed the lane for the night. Deliveries continued like clockwork until 4:00 A.M. Each day, the last pipe was unloaded in time for the truck to be off the road by 5 A.M., so that the lane could open again at 6:00 for early morning rush hour.
