Bridge 5 is located on 2nd line road, 600m east of Seneca Road in Ohsweken, a village Six Nations of the Grand River reserve, near Brantford, Ontario. Built in 1960, the original bridge was a 3-span structure consisting of thirteen pre-cast concrete U-girders that were installed side-by-side without a deck overlay and waterproofing to protect the girders. McIntosh Perry examined and compared the possibility of rehabilitation versus full replacement and because of the major deficiencies, including delaminations, spalls and cracks in the concrete girders and efflorescence leakage at girder joints, full replacement was chosen.
Based on the limited vertical clearance to McKenzie Creek below, McIntosh Perry ultimately decided on a deck on side-by-side box girder design. The design also incorporated updated barriers, sidewalks, lanes and shoulder widths. McIntosh Perry prepared the contract drawings, tender documents, specifications and periodic cost estimates. We also acted as the Contract Administrator, overseeing that the contractor carried out the construction as designed, as well as tracking schedule and budget.
McIntosh Perry worked closely with Six Nations of the Grand River reserve and Indigenous and Northern Affairs Canada (INAC) in order to meet all requirements of both groups in order to secure appropriate funding for the construction of the project.
