SUBJECT:Contract T-38-98

Road and Track Allowance

Reconstruction at Four Locations

Purpose:

To increase the contract price for Contract No. T-38-98, Road and Track Allowance Reconstruction at Four Locations to allow for site conditions encountered on Lake Shore Boulevard West between Symons Street and Royal York Road and on Lake Shore Boulevard West between Kipling Avenue and 23rd Street.

Funding Source:

Funding for this project has previously been approved by Council and is available in the Toronto Transit Commission's Track Reconstruction Program. 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. The work is being undertaken on behalf of the TTC and the funds are available in Capital Account No. C-TR025 - Work for Others to accommodate the extra cost of this Contract.

Recommendations:

It is recommended that the contract price for Contract No. T-38-98, Road and Track Allowance Reconstruction at Four Locations be increased by $150,000.00 net to a total of $1,463,813.41 to accommodate the additional work necessary at Lake Shore Boulevard West between Symons Street and Royal York Road and on Lake Shore Boulevard West between Kipling Avenue and 23rd Street.

Background:

At its meeting on June 3, 1998, the Bid Committee awarded Contract No. T-38-98, Road and Track Allowance Reconstruction at Four Locations to Crownwood Construction Ltd. at a contract price of $1,313,813.41 (GST included).

Discussion:

At the design stage of the project, staff dug test pits and carried out coring on Lake Shore Boulevard West between Symons Street and Royal York Road and on Lake Shore Boulevard West between Kipling Avenue and 23rd Street. The tests were undertaken to determine the existing (environmental) condition of the material to be excavated and to establish the condition of the TTC track allowance pavement structure. The results indicated that there were no unusual environmental conditions and that the existing foundation slab that supports the rail structure was in good condition and did not have to be removed.

During the course of construction the foundation slab was confirmed to be in good condition but was generally deeper than found at the test pit locations As a result additional concrete had to be placed in the infill area to ensure that the rail system could be positioned at the required elevation and would have proper structural support.

Conclusion:

The contract price for Contract No. T-38-98 should be increased by $150,000.00 to a total of $1,463,813.41 to allow for the site conditions encountered on Lake Shore Boulevard West between Symons Street and Royal York Road and on Lake Shore Boulevard West between Kipling Avenue and 23rd Street. This will allow the contract to proceed as scheduled.
