Concrete Pipe Transport/Shipping Services

The bell and spigot ends of reinforced concrete pipe are the most structurally critical and damage-vulnerable points on the entire pipe section. The gasket groove machined into the bell end must arrive at the job site dimensionally intact for the rubber gasket to seat correctly and form a watertight joint. Even minor chipping at the gasket groove from rough handling or inadequate end protection during transport can prevent proper gasket seating, creating an infiltration point in a sewer system that will require excavation and repair after the system is operational.

Reinforced concrete pipe wall thickness increases with pipe diameter and design load class, and that relationship drives section weight up rapidly as pipe size grows. A single section of 72-inch diameter Class IV RCP can weigh 8,000 to 12,000 pounds. A truckload of large-diameter RCP sections reaches legal gross vehicle weight with a small section count, and the individual section weight drives crane and rigging requirements at both the pipe yard and the job site that have to be planned before the truck arrives.

Concrete pipe is manufactured in multiple load classes that determine its structural capacity under fill and traffic loading. The project engineer specifies the correct pipe class for each reach of the system based on burial depth, soil conditions, and traffic loading. Delivering the wrong pipe class to a project creates a specification compliance failure that the project inspector will catch during installation, and replacing installed pipe that fails inspection is one of the most expensive remediation scenarios in civil construction.

Large-diameter concrete pipe sections require crane lifts at every handling point from the pipe yard through installation in the trench. The crane capacity, boom reach, and rigging configuration at the job site have to be capable of handling the heaviest section on the delivery before the truck arrives. A crane that is undersized for the pipe section weight cannot complete the offload, leaving the driver waiting while the contractor sources additional lifting capacity.

Concrete pipe installation in open trenches or supported excavations is time-sensitive from both a project schedule and a safety standpoint. Open trenches create ground disturbance that increases over time, and contractors want pipe in the ground quickly after the trench is open. A pipe delivery that arrives before the trench is ready creates a staging problem. One that arrives after the trench has been waiting creates unnecessary ground disturbance exposure. Delivery timing has to match the excavation production rate precisely.

Public infrastructure projects using concrete pipe almost universally require material acceptance documentation before installation can begin. Pipe class certification, concrete mix design records, and hydrostatic test results for pressure applications are all commonly required by municipal owners and their inspectors. Pipe that arrives on site without proper documentation may be rejected pending testing, which stops the installation operation while documentation is assembled.
