Although the ordering of materials is the contractor's responsibility, supplier and engineer familiarity with the contractor's proposed schedule will enable better coordination to avoid mistakes and possible delays in pipe deliveries. We stock a wide range of pipe sizes and strengths, but production facilities must frequently be adapted to meet specific project requirements, particularly when large quantities and/or special types of pipe are involved.

Unloading of pipe should be coordinated with the construction schedule and installation sequence to avoid re-handling and unnecessary equipment movement. Access to the jobsite shall be provided by the contractor to ensure that the pipe manufacturer's trucks can deliver pipe to the unloading area under their own power. Each shipment of pipe is loaded, blocked and tied down at the plant to avoid damage during transit. However, it is up to the receiver to make certain, damage has not occurred in delivery from the plant to the construction site. An overall inspection of each pipe shipment should be made on arrival, before the pipe is unloaded. Total quantities of each item ...
... should be checked against the delivery slip and any damaged or missing items recorded on the delivery document. If a pipe is damaged during delivery or unloading, the pipe should be set aside. Damaged ends, chips or cracks which do not pass through the wall can usually be repaired.

When a pipe connects to a rigid structure such as a building, manhole or junction chamber, the bedding and foundation for the connecting pipe section should be highly compacted to minimize differential settlement. Differential settlement can result in the pipe being sheared or cracked at the connection. Special connectors are available which provide flexibility between the connecting pipe and the structure.

Joints for pipe sizes up to 24" in diameter can usually be assembled by means of a bar and wood block. The axis of the pipe section to be installed should be aligned as closely as possible to the axis of the last installed pipe section, and the tongue or spigot end inserted slightly into the groove or bell. A bar is then driven into the bedding and wedged against the bottom bell or groove end of the pipe section being installed. A wood block is placed horizontally across the end of the pipe to act as a fulcrum point and to protect the joint end during assembly. By pushing the top of the vertical bar forward, lever action pushes the pipe into a home position. When jointing larger diameter pipe, and when granular bedding is used, mechanical pipe pullers are required. Several types of pipe pullers or come along devices have been developed but the basic force principles are the same.
