Best Practices in Damage Prevention for Parallel Construction Projects

摘要

New pipelines are increasingly being encouraged (or forced...) to share common or adjacent rights of way with existing utilities. Installation parallel to existing underground facilities for long distances greatly complicates construction and damage prevention, and creates a multitude of opportunities for damage to occur. This paper describes current regulatory and industry association efforts to address these issues, and gives a case study of a real accident that was caused during parallel construction of a water main adjacent to an HVL pipeline.
