The singing bridge, Alder Bay, Granville Island, Vancouver, B.C.

A unique design and model for the longest wooden bridge (62 m) in Canada.

An opportunity to leverage a key Canadian renewable resource at a time when we are witnessing substantial change in our natural ecosystems through climate change. Our bridge meets the structural, design and sustainability requirements to develop the use of advanced wooden bridge technology, in an aesthetically beautiful structure.
The “Singing Bridge” is built so that the sounds of a guitar are heard from every step. Every time a visitor crosses the bridge, they hear a different song based on their own movement pattern. The design blends both engineering and aesthetics into one coherent structure, which is:the longest wooden pedestrian bridge in Canada

Challenge

Initially, we undertook this project initially in response to the GC Wood initiative from Natural Resources Canada. We have continued our development of this to the model stage because we appreciate the innate qualities of wood construction and see great potential for creating beautiful wooden bridges and advancing wood technology.

This invitation inspired us and, over the last number of months we have worked to advance a design we believe is quite compelling. We did not qualify for the program without a firm financial commitment from an owner of the bridge to fully fund the structure. Undaunted, we decided to move forward with the box beam design and constructed a proof of concept 1/10th scale model we want to show you. The design blends both engineering and aesthetics into one coherent structure. Wooden structures have, for thousands of years, met very high standards in both elements.

With the idea of taking bridges beyond their utilitarian nature and being design elements that complement their environment. We wanted to create something which respects the history of wooden bridges built literally thousands of years ago and still standing. Emphasizing the many and varied structural and aesthetic benefits of this renewable resource. Doing so in a way that utilizes modern techniques, materials and engineering to produce reliable structures which are pleasing to the senses.

Value

Our bridge is a box shaped composite structure that has several interesting attributes. It is:

** Lightweight,
** Aesthetically pleasing,
** 100% wood construction,
** Water resistant with a shape to prevent ponding and a surface to prevent absorption,
** Harmonically resonant (makes sounds in the same manner as a guitar) as a design element, and
** Easily mass produced.
 
The model is a 1:10 scale prototype of a 67 m long span suitable for Alder Bay (Connection from the False Creek South Slope Seawall to Granville Island). 

We have assembled a team of leaders from Civil Construction, Engineering, Design, Wood Construction and Bridge Building to bring this to life. The team is adept at working within both the design and fiscal constraints of public entities. Together our team has hundreds of years of combined experience designing, building and managing infrastructure projects globally.

We invite you to consider our design and our world class team as you visit or revisit your community's upcoming needs.
