The Rangeview Sanitary Trunk Phase 1, executed between March 2019 and March 2021, was a pivotal infrastructure project in south Calgary, led by the City of Calgary and Volker Stevin, with Bothar Group. The project's goal was to lay down essential wastewater services for future neighborhoods, involving the installation of concrete jacking pipes across a 2.584km stretch.

Engineered Containment's Contribution

Engineered Containment played a crucial role in this project, focusing on the HDPE welding of the concrete protective liner (CPL) in the trunk line. Their work was critical in ensuring a leak-proof containment system, which is vital for the project's long-term success and environmental protection. Engineered Containment's involvement highlighted their specialized skills in environmental protection solutions, particularly in ensuring the integrity of containment systems through rigorous quality assurance and quality control (QA/QC) measures.

QA/QC Measures

A standout aspect of Engineered Containment's work was the meticulous QA/QC on the CPL scope. All joints were spark tested, a method that ensures the welded joints are defect-free and can maintain containment integrity under operational conditions. This level of attention to detail and commitment to quality underscores Engineered Containment's expertise in creating durable and reliable environmental protection solutions.

Project Success

Despite facing challenging conditions, such as extreme weather and the need to navigate complex geographical and environmental constraints, the project was successfully completed and even won the Tunnelling Association of Canada’s Project of the year for 2021. The Bothar team achieved remarkable tunneling rates, and the project stands as a testament to the effective collaboration between multiple stakeholders, including Engineered Containment's specialized contribution to the project's success.
