* Tender prices corrected for mathematical errors. Purchasing and Materials Management has verified that the mathematical errors are corrected.

Scope of Work:

This bridge is one of the structures transferred from the Province in 1997. The records obtained from the Province have shown that the deck and supporting concrete girders were badly deteriorated and needed to be completely rebuilt. In addition, a planning and functional design study was performed to determine the long term transportation needs of this facility. Contract T-28-99 has incorporated all recommendations from this study.

The rehabilitation work involves a complete replacement of the existing structure by a new bridge slightly south and east of its current location. The existing bridge deck carries three lanes of traffic in each direction and has a pavement width of 10.98 m on each side of the deck with no median separating the traffic. The proposed new bridge will have a 1.5 m wide raised centre median and will provide westbound and eastbound pavement widths of 11.0 m. Both approaches on Dixon Road will be rebuilt and re-aligned to the new bridge location. Highway 27 on the north and the south sides of Dixon Road will also be rebuilt and re-aligned in order to provide a 5.0 m vertical clearance under the bridge in accordance with the current Bridge Code.

It is expected that the construction activities will extend from April 18, 1999 to October 29, 1999. Throughout this period, there will be numerous stagings and lane restrictions within this section of Dixon Road as well as on Highway 27. In addition, the lane widths will be reduced and the lane configurations will be altered to create the necessary work zones. As such, a lowering of the speed limit to 60 kilometres per hour on Highway 27 is recommended to maintain safe traffic operations and a safe work zone during the construction period.

Comments:

The tender document submitted by the recommended bidder has been reviewed by the Commissioner of Works and Emergency Services, and was found to be in conformance with the tender requirements.

The award is subject to receipt of a favourable report from The Manager, Fair Wage and Labour Trades Office regarding working conditions and wages of the recommended contractor and his sub-contractors.

Conclusion:

This report requests authority to issue a contract for the bridge reconstruction and associated roadworks on Dixon Road over Highway 27 in accordance with specifications to Graham Bros. Construction Limited, Fairglen Excavating Limited, 795208 Ontario Limited, Graham Bros. Aggregates Limited and Graham Realty Inc. who submitted the lowest price bid for this Contract.

In order to maintain safe traffic operations and a safe work zone throughout the construction period, the speed limit should be reduced from 70 kilometres per hour to 60 kilometres per hour as set out in this report.
