39th IABSE Symposium – Vancouver, BC

Morrison Hershfield has the pleasure of sending three talented bridge professionals to present at the International Association of Bridge and Structures Engineering (IABSE) 39th Symposium. The symposium focuses on topics related to structural engineering of buildings, bridges and other civil infrastructure. Structural engineers are invited from all over the world to share their experiences and lessons learned with our industry. Visit our presenters during the conference to learn about some innovative projects and solutions to unique bridge challenges.

Innovative Expansion Joint Replacement – Burlington Skyway
by Joseph Ostrowski, P. Eng.

Thursday, September 21st – 10:30 am: Want to learn how to provide cost savings, minimalize traffic impacts and  socio-environmental impacts? Joseph will discuss how we were able to deliver all three  while working on the innovative expansion joint replacement design for the Burlington Bay Skyway.

Joe is a seasoned professional with international engineering and business experience in leading edge construction technology. Joe is a Principal of Morrison Hershfield and Manager of Transportation Structures – Eastern Ontario. His 30+ years’ of professional engineering experience includes design, management, research and construction related to both new and rehabilitation projects in Canada and abroad.

A Baseline Study of a Major Viaduct in Toronto for Strategic Planning for the Replacement/Rehabilitation of all Elevated Structure – The F.G. Gardiner Expressway (Gardiner)
by Wilson Lam, P.Eng., B.A.Sc., M.Eng., L.L.M.

Friday, September 22nd – 10:30 am: This case study will describe an approach to assess and recommend an overall strategy in addressing the challenging questions concerning the disparity of life expectancy and maintenance efforts of the existing substructures, and those of the new superstructure, and the correctness of this method of rehabilitation.

Wilson is a Principal and Senior Structural Engineer at Morrison Hershfield.  He has 12 years’ engineering experience with planning, analysis, design, contract preparation, and design review of highway structures.  Wilson was involved in a number of design and study projects related to F.G. Gardiner Expressway – Elevated, an urban viaduct located in Toronto, and was also a co-author of the Bridge Design Training Program using CHBDC for MTO.”

Special Accommodation for Structural Steel Coating of Burlington Bay Skyway
by David Wang, MASc, E.I.T.

Saturday, September 23rd – 8:30 am: Recently the Burlington Skyway in Hamilton, Ontario, underwent a complete replacement of the steel coating on the truss members.  Additional gravity loads and wind loads from the resulting scaffolding and environmental enclosures posed serious structural overload concerns. Learn how we were able to accommodate these challenges and deliver the project on time with no significant traffic delays or disruptions while maintaining structural integrity throughout construction.

David has been a Structural Designer at Morrison Hershfield since 2013. He has experience in the design and planning of highway bridges and culverts.  He specializes in advanced computer-aided analysis of complex truss and shell structures. David’s previous research experience includes the use of ultra-high performance concrete as applied to accelerated bridge construction methods.
