RP 1172 Construction Parallel to Existing Underground Transmission Pipelines – FINAL

1st Edition, April 2014

The American Petroleum Institute (API) recently published the first edition of recommended practice (RP) 1172 for Construction Parallel to Existing Underground Transmission Pipelines. This new RP is intended as a resource to assist all parties to safely manage construction activities of new or modified facilities parallel to existing underground transmission pipelines. Activity of concern includes construction activity that could impact an existing facility, such as excavation or movement of equipment across the pipeline or within the easement that could affect the safe operation of the existing pipeline.

The primary emphasis of these guidelines is on the interaction between existing transmission pipeline operators and those planning to construct in a parallel fashion. Contractors working on behalf of the constructing party, including environmental and survey professionals, design engineers, construction contractors, and operators of excavation and earth moving equipment, are encouraged to engage in work practices that are in conformance with these guidelines. These guidelines have been developed such that they can be incorporated into contract documents executed with contractors and subcontractors by whichever party is involved in or responsible for construction activities.

This RP is available online at the API Publications Store: Product No. D11721.
