The audit of Infrastructure Condition Assessments was conducted to evaluate the management processes and related contracts for condition assessments of the City’s infrastructure. The audit focused on certain infrastructure assets that have not previously been audited, including: bridges, parking garages, parking lots, stormwater drainage assets, streetlights, and sidewalks.
As part of the National Bridge Inspection Standards, the Arizona Department of Transportation performs bridge inspections of about 230 City bridges and culverts. The inspection reports are sent to the Street Operations department for follow-up of maintenance and repair recommendations. The audit found that the department does not have processes in place to guide staff on monitoring and addressing bridge inspection results. Specifically, since 2014, ADOT bridge repair and maintenance recommendations have not been addressed other than the 68th Street bridge.
Additionally, Public Works does not have a program in place to identify, inspect, and maintain bridges that are not required to be inspected by ADOT. These include pedestrian bridges and bridges less than 20 feet in length. Further, ADOT’s bridge inventory for Scottsdale needs to be reviewed to ensure that recently constructed bridges have been reported and non-City owned bridges are removed.
Facilities Management so far has contracted for assessments of 5 of 8 City-owned parking garages. However, the recommended repairs and maintenance have not yet been addressed. The audit also found that the Street Operations department does not meet its goals for drainage asset inspections and reports do not consistently identify visible repair needs that were noted by ADOT inspections of drainage-related bridge structures. The audit recommended policies and procedures, prioritization of work, and monitoring of the drainage inspection program.
Other assets such as streetlights and sidewalks are in the process of being inventoried and have not received condition assessments. Parking lot assessments have been completed sporadically.
The Public Works division agreed with the audit’s recommendations and its action plan is included in the report.
