REPORT TO THE
FINANCE & OPERATIONS COMMITTEE
Report Number: OES 55-02
Date: November 11, 2002
From:
Richard W. Holborn, P.Eng.
Division Head, Municipal Property & Engineering
Subject:
Municipal Structures Improvement Priority Program
Recommendation:
1.
That Report OES 55-02 regarding the City's bridges and culvert structures needs
be received; and
2.
That staff continue to have the system of bridges and culvert structures
inspected and appraised regularly in accordance with the Ontario Structure
Inspection Manual, and indentify maintenance, repair and replacement needs
through the annual Capital budget process.
Executive Summary:
Not Applicable
Financial Implications:
For the next ten year period, the rehabilitation and replacement needs are estimated at
$11,212,000. In order to address the needs, a Capital Forecast of planned
maintenance, repair and replacement is required. Staff recommends that the deck
condition surveys be performed on four bridges at an estimated cost of $40,000,
subject to budget approval in 2003 to confirm repair recommendations.
Background:
The City is responsible for ensuring that bridges and culvert structures on the City road
system are kept safe and in good repair. This has to be done through the performance
of regular bridge inspections (every two years) in accordance with the Ontario Structure
Inspection Manual. Municipalities are also responsible for passing load limit bylaws on
bridges in accordance with the Highway Traffic Act, requiring two professional
engineer's stamps, indicating load posting and duration.

Totten Sims Hubicki Associates (TSH) was retained by the City in 2002 to re-inspect all
forty one bridge and fifteen culvert structures ( spans of 3.0 metres or greater) on the
City road system and prioritize the maintenance, repair and replacement works for
these structures as an update to the 2000 inspection program. Attachments 1 and 2 to
this report illustrates the number of bridges and culverts within the system, their age of
construction and their rehabilitation needs in dollars. It is evident that the City's bridges
that exceed sixty years of age, and culverts that exceed twenty years of age are in need
of rehabilitation or replacement.
Based on the report "Municipal Structures Improvement Priority Program 2002"
prepared by TSH, a summary of the total structure rehabilitation and replacement
needs was compiled. For the ten year period, the rehabilitation and replacement needs
are estimated to be $11,212,000 for the existing City structure system. Of this total
cost, $9,198,000 is for structure Now needs, $1,992,000 for the 1-5 Year needs and
$22,000 for the 6-10 Year needs. There are seven bridges and five culverts that are
recommended for replacement, typically due to insufficient deck width or due to
condition. Four of these bridges are posted with load limits through a municipal by-law.
Thirty bridges and four culverts require rehabilitation work, of which three culverts
require ongoing monitoring. The report identifies six bridges requiring further
engineering investigations, typically deck condition surveys.
A program to further evaluate and prioritize needs is being proposed as a budget line
item under Damaged and Failing Infrastructure category for 2003 Capital Budget. Staff
have identified four bridges which require a Deck Condition Survey for further
engineering investigations to confirm the visual repair, rehabilitation or replacement
recommendations of the structure. The cost for the field work and structural analysis is
approximately $10,000 for each bridge. Based on the information received City staff
will be able to complete a Capital forecast and budget to address the needs of the
municipal structures.
