Design Criteria and Specifications for Pipeline Rehabilitation Projectsby Lawrence I. Erdos,
Abstract: Pipeline rehabilitation, while not a completely new technology, is nevertheless a fairly recent development, just now coming to the forefront as to common usage. It is not however a fail-safe technology, and careful professional judgment must be exercised to assure a successful project that will achieve the design life expectancy. This paper does not purport to address the problem of whether or not a pipeline system requires replacement or rehabilitation. Rather, it assumes that question has been analyzed and answered in the affirmative. This paper then addresses whether rehabilitation is a suitable alternative, and if so, addresses the design criteria to be utilized to determine the various rehabilitation technologies available. Some of the primary considerations for evaluation include structural properties, feasibility, economics and political needs and expediency. This paper will not address all rehabilitation technologies available today. Rather, this paper will discuss only those investigated by the author in conjunction with the Southern California Chapter of the American Public Works Association (APWA) and the Southern California District of the Associated General Contractors of California (AGCC) Joint Cooperative Committee (Joint Committee) in promulgating their Standard Specifications for Public Works Construction (Green Book).
