For the challenging Halfway River Pipe Bridge project in Northern BC, Arch Engineers delivered a comprehensive engineering solution for Graham Construction. The focus was on the intricate in-water work essential to the project’s success. The project involved the design and construction of a 564-meter-long double girder pipe bridge. This required precise planning and execution to overcome harsh environmental conditions and complex logistical challenges.
Key elements of the project included pile installation within the river. This work necessitated the construction of a robust platform capable of withstanding the dynamic river environment. In response, our team designed and constructed berms to protect work areas from potential flooding. As a result, the installation process continued without interruption; even in partly frozen river conditions.
In addition to pile installation, we developed innovative falsework solutions to support 60-meter girder spans. This required coordinating two cranes for tandem lifts of girders weighing up to 73 tons. Furthermore, the temporary shoring designs and installation procedures provided by Arch were crucial. They helped maintain the stability and safety of the worksite.
Despite the remote location and steep access routes, our team successfully navigated the challenges posed by the pipeline right-of-way and extreme winter weather. Ultimately, the Halfway River project was completed to the highest standards of quality and environmental protection. It demonstrated Arch’s ability to deliver complex infrastructure solutions under demanding conditions. Overall, this project highlights our commitment to excellence in both design and execution; ensuring long-term resilience and functionality of critical infrastructure.
