6 American Concrete Pipe Association concretepipe PRE-CONSTRUCTION PRECAUTIONS Federal regulations covering safety for all types of construction, including sewer and culvert instal-lations, are published in the Safety and Health Reg-ulations for Construction under the Department of Labor, Occupational Safety and Health Administra- CONCRETE PIPE BOX CULVERT INSTALLATIONsections should be rolled or lifted and should never be dragged. Pipe sections should not be rolled over rough or rocky ground. The use of mechanical equipment is necessary for unloading arch, elliptical and box sections and larger size circular pipe, and can usually simplify and speed up the unloading of smaller pipe. When Construction About PipelinesConstruction. The sections of pipe will be joined together by welds. Welding shelters are sometimes placed over pipe segments so welders can fuse the segments together while protected from wind or weather. Welders use techniques to make the points where the pipes connect even stronger than the steel in the pipe.
