PURPOSE:

The purpose of this report is to obtain the Council approval to award contract # 042-T-08 John Street Bridge Superstructure Replacement

BACKGROUND:

The John Street Bridge was constructed in 1971, approximately 0.5 km west of Bayview Avenue over the East Don River. The bridge consists of a 12m single span, concrete deck and a concrete substructure. Based on the detailed bridge condition survey, the replacement of the bridge deck was recommended. The Town obtained the TRCA’s approval on August 31, 2007 and Navigable Waters Protection approval on December 27, 2007.

OPTIONS/ DISCUSSION:

On April 7, 2008 Town staff conducting routine bridge inspection and pothole repair discovered severe winter damage that has made the bridge unsafe. John Street was closed between Bayview Avenue and Henderson Avenue on April 7, 2008 for emergency repairs assessment of the bridge. Traffic has been diverted to Steeles Avenue, Proctor Avenue, Royal Orchard Boulevard and Langstaff Road.

Based on the inspection conducted by a professional structural engineer on April 9^th, it was identified that extensive repair work will be required to make the bridge safe to be re-opened to traffic. In consideration of the planned replacement of the deck (originally scheduled to commence in June), staff recommends that the road remain closed and proceed immediately with the planned construction. Due to the condition of the bridge and the immediate need for the replacement of the superstructure, staff is requesting for Council to award the tender.

Marbridge Construction Ltd. submitted the lowest priced acceptable bid and was therefore recommended for the award. Marbridge Construction Ltd. has successfully completed various similar contracts in the past and staff have verified reference checks to ensure that they will provide satisfactory service that meets, if not exceeds the Town’s expectations.

Retaining of Consultant

Since Totten Sims Hubicki (TSH) conducted the Environmental Assessment and the Detail Design for this project, it is recommended that the firm be retained to provide the site supervision and contract administration services in accordance with Purchasing By-Law 143-2000, Section 14 (1) (c) which states “…the extension of an existing contract would prove more cost-effective or beneficial”.

TSH posses’ significant knowledge of the bridge and it is important to ensure continuity from the design phase to the construction phase. TSH has provided a proposal for the contract administration based on 10 weeks of construction period and includes geotechnical consultant’s fee to carry out material testing. TSH has provided quality service to the Town in past bridge projects ad their estimate is comparable to industry rates for such services.
