HWY 400SB Over HWY 407

Brown & Co. was retained by Hwy 407 ETR to review the existing bearings, review existing loads, develop specifications for the bearing replacement and design the jacking system for the lifting and supporting the structure during the bearing replacement.
Brown & Co. confirmed the existing bearing loads with minor changes from the original structure and confirmed that the disk existing bearings were failing by extrusion of the elastomer. Replacement bearings fitting on the existing masonry plates were specified. Jacking of the structure was complex due to space restrictions, depth to foundations and high pier loads. A jack support system consisting of a concrete collars post-tensioned to the existing columns was developed and successfully implemented.
