The projects below are sampled from the personal resume of our Principals to showcase their bridge and seismic engineering experience. This work was conducted while being employed at other firms. As the Spannovation portfolio builds up, we will continue to update this page. Feel free to talk with us about specific value solutions for bridge infrastructure on these projects and more.
Sombrio Bridge, BC
Saqib was the lead engineer for the design of this two span steel plate girder bridge with a highly imbalanced span arrangement of 40m - 82m while at MMM (WSP). Raj led the erection design of the girders through incremental launching. 'The innovative launch scheme added a minor amount of permanent steel (6 tons) to the bottom flange but eliminated the need for a launch nose or a temporary pier in the deep ravine.' - Brad Gunnlaugson, PM, Surespan Construction Ltd.
New Champlain Bridge, QB
Saqib as the design lead for several highway land bridges provided technical leadership to teams in MMM (WSP) offices across Canada. He obtained owner's approval by presenting seismic analysis, methodology and results to the designated seismic expert (Dr. Frieder Seible). He was instrumental in obtaining a waiver for non-linear time history analysis through a demonstration of equivalent seismic performance resulting in cost savings.
Evergreen Line, BC
Saqib technically led the seismic / substructure design of the Special Structures during pursuit and final design on the SNC Lavalin team as an employee of MMM (WSP). He was instrumental in modifying the seismic design criteria through one-on-one meetings with the Seismic Peer Review Panel. 'Saqib's work in convincing the owner to evolve the seismic design criteria amounted to considerable savings for design-build contractor.' - Meiric Preece, Technical Director, Evergreen Line Project
Ft. Nelson River Bridge, BC
Set in northern BC, the project involved replacement of the old superstructure and retrofit of the existing piers for a 430m long eight span bridge. To keep traffic flowing during construction, the existing superstructure was laterally slid onto temporary extensions to existing piers for use as a detour bridge while the new girders were launched in place. Raj acted as the Engineer of Record for the superstructure design during employment with McElhanney.
Federal Way Link, WA
Working for the Aecom-Aecon design build team, Raj and Saqib led the pursuit phase design of approx. 60% of the elevated guideway during employment with McElhanney. They were instrumental in developing structural ATCs including a custom girder design that resulted in considerable savings relative to the baseline design. 'Your design lead to a 33% cost savings on the elevated guideway.' - Darren Nally, Cheif Estimator, Aecon Group Inc.
Deh Cho Bridge, NWT
This $200 crossing is the first permanent bridge across the Mackenzie River. Working for the concessionaire, Raj's team at Infinity Engineering conducted the rapid re-design of the 1045m long bridge. Saqib provided on-site quality assurance on behalf of Associated Engineering. 'This rapid redesign is credited as a significant factor in the successful completion in November 2012.' - Kevin McLeod, Director Highways and Marine Services, GNWT
I-405 RTB ETL, WA
Working for the Graham - Aecom design-build team, Raj and Saqib were responsible for leading the bid design of the seismic retrofit and widening of nine existing bridge structures along I-405 Highway. This work was performed during employment with McElhanney. Saqib led the development and approval of two ATCs through one-on-one meetings with WSDOT's seismic specialist.
Golden Ears Bridge, BC
During employment with Buckland & Taylor (now COWI), Raj led the design delivery of the land structures that included the north and the south high-level approaches, 199A viaduct, 201st viaduct and two pedestrian accesses. Site challenges included high seismicity, weak soils, underground existing utilities and a rail corridor on the Langley side.
208th Street O/P, BC
Twinning and seismic retrofit of an existing interchange bridge including widening of 1km of roadway in an urban setting. Widening was accomplished through a new two lane bridge - a two span precast girder system with an integral pier. Raj and Saqib acted as the Engineer of Record for the new bridge design and seismic retrofit of the existing during employment with McElhanney. 'The design team developed practical solutions reducing project cost.' - Richard Welfing, PM, Township of Langley
