All professions are evolving, and the methodology for installations of pipelines are no different. In dense urban areas; crossings of limited access highways and open water bodies; or crossing of areas with difficult conditions, including high ground water; installation via traditional open cut methodologies are typically more costly and take a much longer duration. For decades, CMA has utilized liners and pipe bursting for gravity sewer applications, but the transfer of technologies from the oil and gas industry to the water and sewer industry has yielded the most transformation in applications for pressure pipe.
A prime example project was the Go Big Go Fast 30” Force Main Rehabilitation and Replacement project for the City of Fort Lauderdale. Split into four phases, this project utilized a blend of HDD and Swagelining to turn over three miles of a single failing 30” force main into two redundant lines with numerous bypass connections. This project utilized four HDDs, three of which were in dense urban areas and the other that crossed a navigable waterway, to build redundant infrastructure. This allowed the team to swageline the existing pipe that had experienced a non-traditional failure and was not viable for CIPP. Constructed in only ten months, including a demobilization for a hurricane, the project received many awards.
