PROJECT

Manion Bay Counter-Weighted Dock Ramp

SCOPE

Arch Engineers designed an aluminum gangway with a dynamic counterweight system to connect an existing abutment to a floating dock at Manion Bay. The design included custom articulating connections to existing infrastructure and featured value-engineered lattice construction to reduce material use. The counterweight system also acted as a safety feature, adapting loading conditions and restricting access as needed.

LOCATION

Manion Bay, BC

PROJECT SUMMARY

The Manion Bay project featured a new aluminum passenger ramp connecting to an existing abutment and floating dock. It included a counter-weighted system that increases load dynamically as the gangway lowers by adding links to the chain. This chain system serves two purposes: it acts as a safety curtain, restricting access outside the gantry, and counter-weights the gangway to ensure stability and safety.

The design used articulating connections into the existing cast-in-place footing, showing our ability to integrate new structures with legacy infrastructure. Through value engineering, we cut material use by 25%. We achieved this with an innovative lattice and node design that maintained structural integrity while optimizing resources.

This project highlights our expertise in cost-effective, technically sound marine access solutions. We respect environmental and community infrastructure needs while integrating advanced safety features like the counter-weighted gangway system.
