Sidewalk Condition Survey

[dsd...@engr.usask.ca]

We are currently preparing to undertake a network level
condition survey to determine the overall condition of
our sidewalks and curbs. With this information we would
like to establish long term funding needs to maintain
our sidewalk and curb network.

Our current rating method defines the severity and
extent of various sidewalk distresses on a per block
basis. Distress severity is measured subjectively
while extent is measured objectively using a distance
measuring wheel. The current system is used exclusively
for developing an annual replacement program using a
worst first prioritization criteria. Small localized
repairs for maintenance crews is generated independently
based on complaints and adhoc inspection by field staff.
We would like to employ a more objective system to
determine sidewalk condition. To accomplish this we are
considering developing a network level condition survey
using a statistical sampling methodology. Our methodology
would include sub-grouping sample groups for inspection
on the basis of material and construction standards,
construction period and/or year of construction, and type
of sidewalk and curb structure. We would be interested
in knowing if anyone has used a statistical sampling
technique for a network wide condition survey. Please send information via
email to:

dsd...@engr.usask.ca

and indicate if you would like a copy of the findings
and reports from other cities. Also indicate whether you
want the information from your municipality to be released.

Thanks in advance...
