SURREY - NEW WESTMINSTER, BC
Stal̕əw̓asəm (Riverview) Bridge - Formally Pattullo Bridge
The stal̕əw̓asəm Bridge is a key connection between Surrey and New Westminster.
The previous bridge (Pattullo Bridge) was built in 1936 and provides 4 traffic lanes with one small pedestrian sidewalk.
Entuitive was hired by the Fraser Crossing Partnership to support prefabrication efforts by providing design, certification, and drawing preparation for Precast Deck Panels and the Batch Plant. These services included oversight of the design of the precast yard, providing construction engineering advice and facilitating logistics planning. Additional responsibilities included preparing precast panel shop drawings. The Entuitive team is paying a critical role in the successful execution of this major infrastructure project for the BC Ministry of Transportation and Infrastructure.
The new bridge design incorporates safe transit for vehicular, pedestrian, and cyclist travel. Streamlined design considerations were employed to reduce the impact of the bridge replacement on the river. These considerations include approximately 2,500 prefabricated deck panels which are manufactured off-site and simply put in place on the bridge without the need for external craneage or form work. The design also allows for New Westminster's future waterfront greenway and includes habitat development and site restoration in Surrey.

Challenge One
The project was delayed before Entuitive became involved and it was clear that the original opening date could not be met. This added a risk to the assignment and a requirement to meet all of our schedule commitments even though the design of all elements was not finalized.
Solution One
This challenge was met by two measures, one being a parametric approach to the shop drawing production process. This allowed for a reduced time frame to create the shop drawings even when changes to the design needed to be incorporated. The second measure was a direct line of communication between the contractor and the designer, minimizing the time needed to incorporate changes in design.
