Purpose:
To increase the contract price for Contract No. T-8-98, Structure Rehabilitation on the Bathurst Street Bridge over the
Toronto Terminal Railways so that additional repair work can be carried out.
Funding Sources:
Funding for this project has previously been approved by Council and is available in Capital Account No. C-TR055,
Bridge Reconstruction Programme. 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. There are sufficient funds available in
Capital Account No. C-TR055 to accommodate the extension of this Contract.
Recommendation:
It is recommended that the contract price for Contract No. T-8-98, Structure Rehabilitation on the Bathurst Street Bridge
over the Toronto Terminal Railways, be increased by $580,000.00 gross and $280,000.00 net to a total of $2,489,813.58 to
accommodate additional repair work.
Background:
At its meeting on February 4, 1998, City Council adopted Urban Environment and Development Committee Report 1,
Clause 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.
