Entrance Bridge Construction Engineering (BF70580)


GeoMetrix was retained by the prime contractor to provide construction engineering services for this major bridge rehabilitation over the Athabasca River. The existing bridge is a railway truss originally constructed in 1913 that was converted into a highway bridge in 1963 with the addition of precast concrete stringers. Due to deterioration the exterior stringers and barriers are being removed and replaced with wider precast panels to improve the roadways function standard. Construction engineering services included providing engineered drawings for the placement of barriers on the bridge that could withstand vehicle impact forces without excessive deflection into the work zone and off the exposed edge of the bridge. GeoMetrix also completed the engineered drawings for the demolition of the existing HC stringers and barriers that required placement of a picker truck and trailer on the bridge to remove and off load the deteriorated components. The crane erection procedure to install the new precast panels was also engineered and required the placement of a 110 tonne crane on the bridge to complete the panel erection. GeoMetrix also provided engineered expansion joint drawings for a revised alternate to expedite the construction schedule.
