Colquhoun Bridge Replacement - Engineering Services

The Municipality of South Dundas invites Request for Proposal (RFP) submissions from qualified engineering consultants. The consultant shall be responsible for carrying all required sub-consultants to complete the design work. Located east of Williamsburg Ontario, the Nash Creek Bridge is a 7.5m wide by 11.5m slab on I-Girders (steel) bridge. The date of original construction is 1950. Unknowns are the historical repair records. The bridge is currently posted (16, 17, 28 ton limits). The traffic count on Colquhoun Rd is less than 200 vehicles per day. The last bridge inspection (2023) noted that the structure was in “fair” condition and will be due for replacement in 2026. The Municipality of South Dundas is looking for an engineering firm to complete an engineering evaluation to assess a range of replacement alternatives and recommend the ultimate solution that should be implemented. The alternatives to be considered as part of the evaluation include: replacement with a traditional bridge structure, replacement with a modular bridge or replacement with large diameter culverts. Based on a review of upstream crossings, the consultant should also consider replacement with a pre-cast culvert.
