Ingersoll Watermain Abandonment, Wonham Street

The County of Oxford is soliciting bids for the Ingersoll Watermain Abandonment project on Wonham Street South, identified as Tender ENG-2026-730. The scope of work involves the abandonment and removal of an existing 200mm diameter watermain, including its support structure and crossing of the Thames River, as well as the partial replacement of the abandoned line with new 50mm diameter PEX and PVC watermains. The project requires strict adherence to the Upper Thames River Conservation Authority permit, geotechnical slope stability assessments for the river crossing, and a comprehensive tree protection plan. Work must be completed within 70 days, with substantial performance and traffic reopening required by the 60th working day. Bidders must submit their proposals via the Bidding System portal by September 22, 2026, at 2:00 P.M. Requirements for submission include a 35,000 dollar tender deposit, an agreement to provide performance and payment bonds for 50 percent of the bid amount, and detailed schedules covering contractor experience, subcontractors, supervisory personnel, and equipment. Evaluation is based on the provision of three similar project examples from the last five years and a lump-sum price. The successful contractor will be responsible for all site-specific health and safety protocols, WSIB compliance, and materials testing in accordance with Ontario Provincial Standard Specifications and Oxford County Design Guidelines.
