Abstract: Every pipe bursting project should be evaluated based on the complete data set of information available. The data should be thoroughly vetted by the design engineer, owner and contractor in order to get a clear picture of the project complexity. This evaluation should be done during the life cycle of the project from design through construction. Every project has its own unique set of challenges, which are made easier to face when they are planned challenges. The static pipe bursting project located in the City of St. Catharines in Ontario Canada was one such project with many planned challenges. Avertex Utility Solutions Inc. out of Ontario has been in the underground business since 2003 so they have seen their share of challenges. This particular project, although short in pipe length, was long on challenges. The project consisted of replacing a 230-foot (70m) section of 18-inch (450mm) PVC gravity feed sanitary sewer pipe, 32 feet (10m) deep, located between two houses, collapsed down to 4 inches (101mm) with very high flow with 18-inch (450mm) HDPE. The owner, design engineer and contractor had to come up with a plan for all of these challenges. This paper will focus on how the challenges of pipe bursting a high flow line with extreme pipe collapse, pipe depth, and sensitive confined residential workspace were planned for and overcome and how HDD, pipe bursting and bypass pumping were utilized to complete the project.
