Across the world, municipalities and buried pipelines owners are seeking innovative, cost saving, low impact, and safe technologies to renew their aging underground infrastructure; pipe bursting construction method is a viable option. Pipe bursting is a trenchless pipe replacement method in which deteriorated pipes are replaced with new pipes of the same or somewhat larger diameter.
Since its beginning in the early 1980s in the UK, pipe bursting has been successfully utilized on an international scale and has gained recognition as the only trenchless pipe rehabilitation method in which a buried pipe can be replaced with a completely new pipe that functions independently of the existing host pipe and permits the diameter of the new line to be increased. Like many trenchless pipeline installation methods, pipe bursting is subject to multiple construction risks, which can also have both direct and indirect effect on the project cost, schedule, quality, and safety.
While pipe bursting has been successfully utilized as an innovative pipeline renewal method, the common mistake in the industry is to think of it as a ‘silver bullet’ pipeline renewal method. This course aims to (i) provide an overview of the common bursting systems currently used in North American, (ii) discuss factors to consider when analyzing the viability of pipe bursting for a pipeline renewal projects, as well as potential risks, and (iii) discuss the planning, design and construction requirements for successful installation of new pipeline utilizing pipe bursting method.
This course concludes with two case studies describing scenarios where in one case, pipe bursting was considered a ‘no-go’ option and in the other, the most viable option. Through knowledge and experience sharing, this submission aims to provide guidance to decision makers on the application, strengths and limitations of pipe bursting as a trenchless pipeline construction method.
