API RP 1172

Description

The primary emphasis of these guidelines is on the interaction between existing transmission pipeline operators and those planning to construct in a parallel fashion. These activities may involve many different parties. 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 should engage in work practices that are in conformance with these guidelines, and apply vigilance in identifying unanticipated circumstances that may indicate a problem. This RP refers to all of these entities as the “Constructing Party”. 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.
