Discussion:
The former Metropolitan Toronto Council had authorized the dismantling of the section of the F.G.Gardiner Expressway
between the Don Valley Parkway and Leslie Street. A report recommending the award of a contract for the railway
relocation (Contract No. T-54-98) along LakeShore Boulevard from the Don Valley Parkway to Leslie Street was presented
to the Urban Environment and Development Committee on July 13, 1998. At the meeting, the Urban Environment and
Development Committee deferred consideration of the award of the contract until its meeting scheduled to be held on
October 5, 1998. The physical demolition of this section of the Expressway, if Council directs, will take place some time in
the future (likely in the year 2000) following the completion of all required preliminary works.
This section of the Expressway has not been rehabilitated since it was built in 1964. The deterioration of this portion of the
Expressway has accelerated to such a critical level that emergency repairs to the substructure must be undertaken in order
to keep the Expressway in service until dismantling.
At the design stage, staff performed detailed visual inspections on the substructure in accordance with the Structure
Rehabilitation Manual issued by the Ontario Ministry of Transportation. The required emergency repairs to the south
cantilevers and bearing seats were identified.
During the actual repair work, a more thorough limited delamination survey was conducted to assess the general conditions
of the bent cap beams. It was found that there were numerous large areas of delamination on both the vertical faces and
soffit of the cap beams. These areas are directly over the westbound lanes of Lake Shore Boulevard. The delaminations will
eventually spall as a result of continued corrosion of the reinforcing steel as well as vibrations from traffic on the
Expresswayabove. Consequently, this will pose a potential threat to motorists currently using the Lake Shore Boulevard
Westbound.
It is therefore recommended that, as a safety measure, this delaminated concrete be removed as soon as possible.
Conclusion:
The contract price for Contract No. T-47-98 should be increased by $250,000.00 to a total of $1,036,920.80 so that the
additional emergency work can be carried out.
