Estimated Rehabilitated or Replacement Structure Dimensions3

Repair and Rehabilitation Required

1 - Indicate specific costs for structure replacement OR for rehabilitation under the given headings.

2- Give a very brief description of the rehabilitation work required in the Overall Structure Notes section

3- Estimated structure dimensions after completion of the proposed work if it is expected to change.

4 - Includes other construction costs associated with the structure. Engineering fees for reports, environmental studies, designs, project management and

contingencies are not included as associated work.

5- Approach cost is for work (fill, pavement, guide rail, etc.) immediately adjacent to the structure (30m per end) to adjust for minor changes in horizontal or

ertical alignment and for barrier end treatments at the structure.
