Connors Road Pedestrian Bridge – Crane Mats

 

As part of the City of Edmonton’s Valley Line Southeast expansion project, an existing through truss bridge carrying pedestrian traffic over Connors Road in Edmonton was due for replacement. The new Kâhasinîskâk bridge, a sinusoidal shaped through steel plate box girder bridge, was designed by the TransEd LRT Group to replace it. Supreme Steel was responsible for fabrication, delivery and erection of the new steel bridge superstructure.

GeoMetrix was retained by Supreme Steel to design crane outrigger mats for the cranes used in removal of the existing truss bridge, and for erection of the new Kâhasinîskâk pedestrian bridge. The cranes were positioned directly over various City of Edmonton buried utilities including: PVC Drainage Pipes from 0.200 m to 0.450 m diameter, and a 0.762 m diameter Steel Water Main Pipe. GeoMetrix assessed the ground pressure experienced by the utilities and reviewed their conduit (PVC or Steel Pipe) for structural integrity and ability to support the added crane live load. The rig mat size and structural design was tailored accordingly to ensure a safe transfer of loading to the underground utilities.
