Kingston Third Crossing (Waaban Crossing)

The largest transportation investment inKingston’s history.

The first use of Integrated Project Delivery (IPD)for a bridge project in North America.

Named the Waaban Crossing tocelebrate stories and contributions of Indigenous communitiesin the region.

Design achievement withthe tallest and longest NU precast,prestressed concrete one-piece girders in Ontario and the second in Canada.

Challenges

As part of the City’s largest infrastructure project in modern history, theCity of Kingston invested in design and construction of a 1.2-kilometer-long signature bridge over the Cataraqui Riverwhich forms part of the Rideau Canal, a United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Site and Federally regulated navigable waterway.
This major investment aims to provide a much-needed third connection between communities on the east and west of the Cataraqui River, improve emergency services and response, provide an alternate route for the provincial Hwy 401, relieve traffic flow, promote active and public transportation alternatives, and accommodate future growth in the region.
With $180 million in funding from all three levels of government, and a unique IPD Team partnership between the City, contracted design (Hatch and SYSTRA-IBT) and construction (Kiewit), and trade partners Bauer Foundations Canada and Walters Group firms, the project needed to minimize costs and risks as early and effectively as possible.
Design and construction engineering had to consider the bridge’s proximity to the area where the Cataraqui River forms part of the Rideau Canal and other site-specific conditions.

Solutions

The first bridge construction project to adopt the IPD model in North America. IPD projects aim to connect all partners together from the onset to set shared goals and maintain shared accountability and ownership to deliver the best project possible.
Utilized Building Information Modeling (BIM) to improve design efficiency and productivity, and gave the City, contracted design and construction firms a better visual understanding of the project’s concept and scope.
Leveraged BIM to lower project risks and costs, accelerate on-schedule delivery, improve overall integrated design, and minimize errors and rework.

Highlights

Conducted bridge optimization through material selection and structural analyses to generate an estimated $12 million in savings to the target cost budget.
Successfully navigated supply constraints and the rising price of steel by changing materials to concrete, lowering the bridge profile, and changing the main bridge section from an “above deck supported” arch to a “below deck supported arch”.
Optimized the bridge design to reduce the overall in-water footprint by over 50% from the Environmental Assessment (EA) bridge design.
土堆运河herita最小化视觉冲击ge site by partnering closely with Federal and Provincial environmental and heritage regulators, as well as Indigenous communities and surrounding residential communities.
Implementation of a temporary rock causeway -trestle solution instead of using a full-length trestle to keep the Rideau Canal navigable between Spring and Autumn.
