Report No.: DTS 07-169
Subject: 2008 DUKE & ONTARIO GARAGE POST TENSIONING
TENDON REPAIRS-CONSULTANT SELECTION
RECOMMENDATION:
That Council waive the consultant selection process and award the 2008 Duke and Ontario
Garage Post-Tensioning Tendon Structural Engineering Services to Read Jones
Christoffersen Ltd.
BACKGROUND:
Funds in the amount of $1,025,000 have been allocated in the 2008 Capital Budget to
undertake structural repairs in the Duke and Ontario Parking Garage which will include the
replacement of the post tensioning tendons on the P2 north and P5 north and south levels. This
work will also include the repair of any delaminated concrete and the installation of a new
waterproofing membrane on these levels.
REPORT:
Read Jones Christoffersen Ltd (RJC) has been undertaking the structural analysis of the Duke
and Ontario Garage with specific focus on the post tensioning tendons. There is considerable
merit in using the same structural engineers since they are one of the leading firms in the
industry with extensive experience related to post tensioning structures. They are also familiar
with the Duke & Ontario Garage, the history of the repairs and monitoring programs and can
undertake the work with minimal start-up costs. RJC has been the structural engineering
consultant for both the 2005 and 2006 repair program. The engineering fees will be negotiated
in consultation with the Director of Purchasing and the City Solicitor and in accordance with
accepted industry rates as recommended by the Consulting Engineers of Ontario.
Given the nature of the work and the benefits of continuity that RJC provide, it is our
recommendation that Read Jones Christoffersen be awarded the 2008 Duke and Ontario
Garage Post Tensioning Tendon Structural Engineering Services and that Council waive the
consultant selection process.

The selection of the General Contractor to perform the actual repairs would be tendered through
