Item - 2016.EX20.14

Michael D'Andrea, Executive Director, Engineering and Construction Services, gave a presentation to City Council on this Item.

The Executive Committee recommends that:

1.  City Council authorize the Executive Director, Engineering and Construction Services, to proceed with the new approach for the implementation of the Revised Strategic Rehabilitation Plan for the F.G. Gardiner Expressway, as described in the section titled "New Approach for Implementation of the Revised Strategic Rehabilitation Plan" in the report (November 23, 2016) from the Deputy City Manager, Cluster B and the Deputy City Manager and Chief Financial Officer.

2.  City Council direct the General Manager, Transportation Services, to include the revised cash flows associated with the new approach to the implementation of the Revised Strategic Rehabilitation Plan for the F.G. Gardiner Expressway within the Transportation Services 2017-2026 Capital Budget and Plan for Council's consideration.

3.  City Council direct the Executive Director, Financial Planning, the Executive Director, Engineering and Construction Services, and the General Manager, Transportation Services, to report annually on the status of the implementation of the Revised Strategic Rehabilitation Plan for the F.G. Gardiner Expressway.

This report provides a summary of the current issues and concerns surrounding the previously approved procurement strategy for implementation of the F.G. Gardiner Expressway Revised Strategic Rehabilitation Plan and recommends approval of a new implementation approach that would permit the City to proceed as quickly as possible with the F.G. Gardiner Expressway's urgent rehabilitation needs.

The new approach involves:

1.  Implementing the necessary rehabilitation work for the "elevated" section, west of Cherry Street, and the entire "at-grade" section of the Expressway using multiple contracts under an accelerated design-bid-build approach;

2.  Incorporating construction contract terms and conditions to reduce schedule risk and promote additional opportunities for acceleration of the work; and,

3.  Undertaking the preliminary engineering design for the implementation of the Gardiner East Environmental Assessment Hybrid Alternative Design 3, incorporating, where feasible, the scope of work for relevant elements of other large projects planned within and adjacent to the Gardiner East work zone, in order to assess project risks and construction schedule before deciding on an appropriate project delivery approach.

The new approach recommended in this report provides for the phasing of the rehabilitation based on the current structural condition of the Expressway, incorporates proven techniques for mitigating the anticipated traffic congestion associated with this scale of construction, and provides the necessary additional technical information required to fully assess project risks and opportunities to advance the construction of other projects within the work zone of the eastern section of the Gardiner Expressway as one integrated project.
