Asphalt Walkway Repaving and Concrete Walkway Replacement

This project will consist of repairs to existing asphalt walkways located on the northern perimeter of the existing building and to the west along the Rideau River. The existing walkway has and continues to deteriorate. It now represents a Health & Safety hazard to potential users and can no longer be considered accessible. The pathways are to be assessed by a landscape architect.

Recommendations for repair options will be made to PSPC. The most likely course of action is a re-paving project to resurface the pathway ensuring it is graded correctly with new asphalt topping.

The pathways are in some cases located as close as 5 meters to Rideau River, and there is known shallow soil contamination on the property. The project will remove as little material as possible and does not anticipate excavation to be required below a depth of 12-16 inches.
