Sixense awarded monitoring contract for Pattullo Bridge replacement project – Canada

A major bridge project allowing a safer, easier, and toll-free commute

The existing Pattullo Bridge is an arch bridge that connects New Westminster and Surrey and provides on average 75,700 cars and 3840 trucks a daily option for crossing over the Fraser River in the Metro Vancouver area. At the start of 2020, Fraser Crossing Partners (a joint venture between ACCIONA and Aecon Group inc ) was selected to design and construct the replacement bridge. The improved crossing will feature four modern, wider lanes for traffic, with allowance for a potential future expansion to six lanes, pedestrian and cyclist access, and better connections to, from, and near the bridge. 

 

Multi-stakeholder project site requiring innovative and safe solutions

A light rail tunnel, two additional bridges (one light rail, one heavy rail) and the existing Pattullo Bridge, are all located within proximity of the location of the new bridge alignment. Sixense was chosen by Fraser Crossing Partners to develop a monitoring solution that will encompass the surrounding major structures and railways enabling continued safe use of the nearby infrastructure throughout the Project construction.  

Through coordination and cooperation with a variety of infrastructure owners, Sixense has designed and implemented a comprehensive monitoring solution, including 13 Sixense patented Cyclops AMTS systems monitoring hundreds of prisms, 9 4D-BLOC GNSS sensors, 28 vibration monitors and 46 wireless tilt sensors.  

 

An ongoing partnership until the project completion

The innovative monitoring system will be actively administered and maintained by Sixense, delivering near-real-time data on the Geoscope platform to all involved stakeholders. Uninterrupted, safe operation of all surrounding infrastructure will continue to be enabled by the Sixense solution through project completion.
