Design and Construction of the Terwillegar Park Stressed Ribbon Footbridge




In January 2013, the City of Edmonton called for proposals for a new 300 m (990 ft.) footbridge across the North Saskatchewan River. Consultants were challenged to develop concepts that were innovative, fit the context of the deep natural river valley, and could meet strict budget and schedule requirements. In October 2016, the longest and first multi-span stressed ribbon bridge in Canada was opened to the public. It is the second longest in the world. The Terwillegar Park Footbridge was designed by Stantec Consulting Ltd and forms a key link in the river valley park system. Although stressed ribbon bridges are relatively common in Europe, there are only a handful constructed to date in North America. Stressed ribbon bridges can be described as precast concrete structures that are erected segmentally on cables and post-tensioned to achieve a continuous, slender, prestressed concrete structure. The superstructure is stressed between two abutments which are fixed to the ground using an extensive system of ground anchors. These elegant and durable structures are constructed without expansion joints. The presentation will describe the conceptual and preliminary design process and share lessons learned in the design and construction of this elegant and innovative structure.

He has been involved in the inspection, design, rehabilitation, project management, and construction management of all types bridge engineering projects, as well as structural failure investigations, expert testimony, and reports. This has included projects throughout Canada and in the U.S., the Caribbean, China, Pakistan, and the Middle East. He is a member of many technical organizations including the IABMAS Scientific Committee and Bridge Management Committee, TRB Committees AHD30 Bridge Preservation and AHD35 Bridge Management, Transportation Association of Canada (TAC) Structures Standing Committee, and ACI (past Alberta chapter president).




Bridge Analysis & Design Software CHBDC CSA S6-25 Update MIDAS One-Day Hands-On Training

MIDAS and CSCE Edmonton Section are co-hosting an on-site hands-on training program in Edmonton on Thursday, December 7th, 2017.

During this 1-day training, the entire group will try out and learn how to use the software for modeling, analysis and design of a composite girder bridge model in 3D. Junior engineers will learn how to use midas Civil from the start; senior engineers and engineering managers will get to explore the new CHBDC design checking feature and its output reports. Along with our software training sessions, we will present about some of the local projects done by our user engineers and share how they have utilized midas Civil efficiently. Lastly, MIDAS will also share the plan to further strengthen the relationship with Alberta engineers and firms. Registration deadline is November 24th; since seats are limited, please be sure to register as soon as possible using the invitation below. The registration may be closed early depending on demand.
