Arch Engineers Ltd. was engaged to develop a crane-assisted de-launch methodology for the removal and salvage of a steel structure bridge located within an oil pipeline right-of-way. This project demanded a precise and controlled approach to ensure the safe dismantling of the bridge while preserving the structural integrity of salvageable components.
The methodology combined the use of an excavator and a crane to execute the de-launch. The excavator was tasked with pulling the bridge past its pivot point, initiating the removal process. Simultaneously, a crane was employed to provide critical support during this transition phase, ensuring stability and preventing uncontrolled movement as the bridge was de-launched.
Arch Engineers meticulously designed the removal process to address site-specific constraints, including the operational footprint of the machinery and the need to minimize disruption to the surrounding environment. The method ensured that the bridge could be safely dismantled in stages, optimizing salvage and recycling opportunities while adhering to strict safety and environmental standards.
This project highlights Arch Engineers’ ability to deliver tailored engineering solutions for complex structural challenges, balancing precision, safety, and sustainability in infrastructure removal projects.
