The City of Edmonton retained Associated Engineering to complete the Bridge Condition Assessment and Preliminary Rehabilitation Strategy Reports for three bridges at the intersection of 170th Street: B185 over Yellowhead Trail & B170/B171, to the north, crossing over the CN Rail Bissell Yard.
AE is providing project management, condition assessment, load evaluation, & preliminary rehabilitation strategy reports. Project management includes invoicing, progress meetings, utility & CN Rail coordination, and site safety as prime contractor for site condition assessment work. The condition assessments were completed in Sept/Oct 2015 and included review of the bridge’s history, completion of City’s Enviso checklists, detailed visual inspection & materials testing. Material testing included chloride ion content, rebar depth measurement, delamination survey, and partial depth concrete removals. The preliminary rehabilitation strategy included review of controlling factors (structural condition/utilities/traffic staging/ environmental issues), and development of 3 rehabilitation options including economic comparison which considered both capital cost and net present value over the next 60 years.
