The Treasurer has previously certified that financing can be provided under the updated Debt and Financial Obligation limit and that it falls within corporate debt guidelines.

Background:

At its meeting on February 4, 1998, City Council adopted Urban Environment and Development Committee Report No. 1, Clause No. 9 awarding Contract No. T-8-98 Bathurst Street Bridge over the Toronto Terminal Railways south of Front Street to Grascan Construction Ltd. and Torbridge Construction Ltd. at a contract price of $1,909,813.58.

Discussion:

The Bathurst Street bridge is a nine-span structure and the most northerly steel truss span is owned by CN Rail. The southerly eight spans are under the City of Toronto's jurisdiction. In this contract the work includes repairs to the CN truss span and the cost of such will be recovered from CN Rail.

During the design stage, staff performed detailed visual inspections as well as a condition survey on the structure in accordance with the Structure Rehabilitation Manual issued by the Ontario Ministry of Transportation. On this basis the scope of the repair work was determined.

After initiating the removal of deteriorated concrete on the substructure, it was found that the piers were in poorer condition than originally determined from the condition survey test results. In addition, the supporting steel for the sidewalks and the steel components on the truss span were found to be in a poorer condition than anticipated. This has resulted in the need for additional repair work.

Approximately $300,000.00 out of the $580,000.00 additional funds will be recovered from CN Rail and the Toronto Transit Commission.

Conclusion:

The contract price for Contract No. T-8-98 should be increased by $580,000.00 to a total of $2,489,813.58 to enable additional repairs to be completed.
