Dear Ms. Wong:

At its meeting on Wednesday, August 19, 1998, the Commission considered the attached report entitled, "Confirmation Of Additional Project Approval - Roofing Rehabilitation Program."

The Commission approved the Recommendation contained in the above report, as listed below:

"It is recommended that the Commission confirm the approval provided by the Chair, Vice-Chair and Chief General Manager with regard to the following:

1.authorize staff to undertake previously unscheduled urgent work in 1998 under 3.1 Finishes - Roofing Program noting that additional expenditures of $1,530,000 will be required to the end of 1998 and noting that full project documentation will be provided in the 1999-2003 Capital Program submission;

2.forward this report to the City of Toronto Council requesting additional project approval (City project no. 311) be granted in the amount of $1,530,000 gross ($765,000 net), for a total City approval of $5,744,000 to cover cashflow requirements to the end of 1998 and reducing the project approval for project 6.1 Environmental Programs (City project no. 610) by a corresponding amount and noting that there is no net increase in the overall TTC budget; and

3.authorize staff to proceed with project expenditures, due to the critical nature of this request and hold in TTC accounts, pending City Council project approval."

The foregoing is forwarded to City of Toronto Council for the necessary approval, as detailed in the report.

Sincerely,

Vincent Rodo

General Secretary

MEETING DATE:August 19, 1998

SUBJECT:CONFIRMATION OF

ADDITIONAL PROJECT APPROVAL -

ROOFING REHABILITATION PROGRAM

RECOMMENDATIONS

It is recommended that the Commission confirm the approval provided by the Chair, Vice-Chair and Chief General Manager with regard to the following:

1.authorize staff to undertake previously unscheduled urgent work in 1998 under 3.1 Finishes - Roofing Program noting that additional expenditures of $1,530,000 will be required to the end of 1998 and noting that full project documentation will be provided in the 1999-2003 Capital Program submission;

2.forward this report to the City of Toronto Council requesting additional project approval (City project no. 311) be granted in the amount of $1,530,000 gross ($765,000 net), for a total City approval of $5,744,000 to cover cashflow requirements to the end of 1998 and reducing the project approval for project 6.1 Environmental Programs (City project no. 610) by a corresponding amount and noting that there is no net increase in the overall TTC budget; and

3.authorize staff to proceed with project expenditures, due to the critical nature of this request and hold in TTC accounts, pending City Council project approval.

FUNDING

Project approval of $4,214,000 (based on an estimated final cost of $7,591,000) was provided under the 1998-2002 Capital Program 3.1 Finishes - Roofing Rehabilitation Program as approved by the City of Toronto Council at its meeting of April 29, 1998. This request exceeds that approval by $1,530,000 for this project but sufficient underexpenditures are available under other projects in 6.1 Environmental Programs to accommodate these overexpenditures.

BACKGROUND

At its meeting of July 15, 1998 the Commission agreed to cancel the meeting scheduled for August 5, 1998. In addition, the Commission approved delegating signing authority for all procurement reports over $100,000 to the Chair, one other Commissioner and Chief General Manager between July 15, 1998 and the August 19, 1998 Commission meeting; and further that all matters approved in this manner must be brought forward for confirmation at the August 19, 1998 meeting of the Commission.

The Commission has approximately three million square feet of roofing over its stations, maintenance facilities, offices and utility buildings. These roofs include a wide variety of construction types and materials which normally have useful lives ranging from 15 to 25 years before rehabilitation is required.

Many of the roofs are approaching or have surpassed normal life expectancies of 15 to 25 years and repeated spot repairs are becoming inefficient and expensive. Prior to 1996, annual maintenance was restricted to localized repair and patching of leaking roofs with no established program of replacement or major rehabilitation. This resulted in an overall decline in the condition of the Commission's roofs. In 1996, a multi-year Roofing Rehabilitation Program was initiated to return the roofs on Commission buildings to a state of good repair.

An inventory was compiled, priority locations were identified and a program has been developed which allows approximately 80,000 sq. feet of roofing to be rehabilitated each year. The scope of work consists of full or partial roof structure replacement depending on the results of detailed condition surveys carried out on a case by case basis.

DISCUSSION

Recent detailed condition surveys undertaken for planned future work locations have identified Sheppard Station Bus Transfer Facility and Greenwood Overhaul and Repair Shop as being "very high" risk locations which should be given top priority for remedial work. Sheppard Station was previously scheduled for reconstruction in 1999 (not included in current project approval) but is now planned to be completed in 1998 to replace exposed and deteriorated roof felts and split felt flashing along its perimeter area.

Greenwood Overhaul and Repair Shop was originally constructed between 1963 and 1965, and the roof was partially rehabilitated in 1986, 1988 and 1989. As a result new work was not previously scheduled in the approved 1998-2002 Capital Program. However, recent condition surveys initiated to investigate the presence of roof blisters also discovered that the rehabilitation work done in 1989 utilized "phenolic" type insulation in the roof structure which can cause acidic attacks and premature corrosion and failure of the steel decking. As a result this location has also been classified as "very high" risk and should also be completed in 1998. Action is being taken to recover any portion of rehabilitation costs that can be attributed to the supply and installation of "phenolic" insulation from the contractor and/or the supplier of that material.

The additional funding required to carry out these works in 1998 is $1,530,000. Of that amount $232,000 represents a timing change for Sheppard Station from 1999 to 1998, and $1,298,000 represents new previously unbudgeted costs for Greenwood Overhaul and Repair Shops.

JUSTIFICATION

The additional work identified should be completed in 1998 to address recently identified "very high" risk locations at Sheppard Station and Greenwood Overhaul and Repair Shop in order to return these facilities to a state of good repair and avoid accelerated deterioration and increased risk of leakage damage at these locations.
