b.         Revised Strategic Plan for the rehabilitation of the F.G. Gardiner Expressway, including project delivery schedule, multi-year cashflow requirements and financing strategy for the implementation of the Strategic Plan should City Council opt for either the remove, replace or improve option for the Gardiner East Environmental Assessment Study.

3.         City Council grant authority to amend Purchase Order No. 6036736 with Marshall Macklin Monaghan Ltd. to reflect the additional work required to revise the Strategic Rehabilitation Plan by an additional amount not to exceed  $350,000.00 net of all taxes, including contingencies and revising the current contract value from $ 2,068,005.90 net of all taxes ($2,140,402.80 net of HST recoveries) to an upset limit of $2,418,005.90 net of all taxes ($2,460,562.80 net of HST recoveries)

4.         City Council grant authority to award Contract 13SE-19S, Tender Call No. 314-2013 to Grascan Construction Ltd., for the "F.G. Gardiner Expressway, CNE to Grand Magazine Street, Deck Replacement and Garrison Road Bridge Demolition", in the amount of $66,500,000.00 net of HST ($67,670,400.00 net of HST recoveries) having submitted the lowest compliant bid and meeting the specifications in conformance with tender requirements.

5.          City Council request that the Executive Director, Engineering and Construction Services, ensure that any future rehabilitation work on the F.G. Gardiner Expressway is compatible with the re-alignment of Lake Shore Boulevard as outlined within the Western Waterfront Master Plan (2009).

The report presents a summary of the proposed Strategic Plan for the rehabilitation of the F.G. Gardiner Expressway, extending from Highway 427 to the eastern limit at Logan Avenue, including the "at-grade" and "elevated" sections is presented in this report.  The report includes an assessment of the current condition of the Expressway, a prioritization of rehabilitation works, and presents a comparison between the conventional and accelerated approaches for the rehabilitation in terms of project schedule, capital costs and user impact costs associated with the construction of the rehabilitation works.

The approval of an innovative, accelerated approach for the rehabilitation of the Expressway is being recommended.  The approach involves scheduling rehabilitation work for the "at-grade" section with the replacement of deck for the "elevated" section, which has reached the end of its service life, using prefabricated deck/girder sections.  While this approach represents an initial increase of an estimated $400 million in Transportation Services' 2014 to 2023 Capital Budget and Plan, the longer term cost differential over the 25 year implementation period using the conventional approach is estimated to be $115 million.  This increase in capital costs is more than offset by the reduction in traffic and user impacts by an estimated eight years and user impact cost of $3 billion.

This report also advises on the results of Tender Call No. 314-2013 issued for the replacement of the West Deck of the elevated section of the Expressway from Exhibition Place to Grand Magazine Street (west of Bathurst Street).
