ASSET MANAGEMENT
Bookshelf APWA Bookstore Free Online
From APWA “Public Works Management Practices Manual, ” Version 7
Why Manage Assets? • Justify funding for preventative maintenance • Establish scope and timing of rehab/replacement • Establish budget/staffing to meet maintenance needs. • Establish inventories for parts and materials. • Evaluate effectiveness of new materials/methods. • Build credibility with public/elected officials. • Provide expected Level of Service (LOS) • Establish “net worth” of asset to comply with GASB 34 – (modified accounting method)
Asset Management Questions: • • • What do I have? Where is it located? What condition is it in? What is its life expectancy? What condition will it be in the future? What’s my goal for its condition (LOS)? Should I maintain or replace it? How much should I budget for it? What is my annualized cost for this asset?
Why Manage Assets? Adapted from EPA’s Fact Sheet “Asset Management for Sewer Collection Systems” From “Pavement Management for Airports, Roads, and Parking Lots”, M. Y. Shahin
“Stages of Asset Management” • Stage 1: Inventory – Network Division – GIS – Attributes • Age • Cost • Stage 2: Condition – Repeatable measurement – Reliable/accurate – Comparative standard • Stage 3: Life Expectancy – Sophisticated models – Simple Time to failure • Stage 4: Full Asset Management – – Model options Optimize expenditures Meet level of service goals Reduce political influence 9
Maturity Scale
Asset Management Databases • • GIS Traffic Count Crash Data Asset Inventory Asset Condition Asset Vulnerability Climate Conditions (NOAA, Storm. Watch) Soil Characteristics
Life Expectancy Models • Straight-line depreciation • Manufacturer’s recommendations • Deterioration models • Lifecycle preservation model
Condition Inspections Need to be: • Based on Established Inspection Standards • Repeatable • Reliable • Sampled or complete • Frequent
How Much to Inspect? • Complete • Partial • Small Samples
Small Sampling Common characteristics allow a small sample to reliably measure condition of entire asset: • Age • Materials • Load/Use • Maintenance History Individual assets need to be carefully selected to enable small sampling statistics
OP Assets • • • • Poles Signs Lights Wiring Junction Boxes St. Light Controllers Cable Street Light Wiring Fiber Optic Cables Conduit Signal Cabinets Signal Controllers Signal Heads (incl. DMS) Auxiliary Equipment Pavement Markings • • • Streets Street Curbs Sidewalk Ramps Storm Sewer Lines Storm Sewer Structures Storm Sewer Outfalls Fence Guard Fence Walls Bridges

Impact of Plan on Network
Modeled Network Performance Increasing funding from $7. 7 M to $12 M stabilizes network condition

WORK MANAGEMENT
Work Management • What? – Managing labor, material and equipment – Recording time and costs associated with assets – Keeping maintenance records and tracking work • Why? – – – – Tracking Service Requests Work Scheduling/Planning Performance Measures Access to Historical Data More Efficient Use of Resources Reduce Equipment Downtime FEMA Reimbursements
Service Requests • • • Web-based submission Phone Walk-ins Routing based on work rules Automated alerts
Internal Data Entry Form
Custom On-line Interface
Automated Alerts
Work Scheduling/Planning Reactive Proactive • Potholes • Street Light Outages • Accident Response • • • Street Sweeping Inlet clean-out Equipment Maintenance Crack Seal Programmed Street Maintenance
Web-based Interface (Customized for Utility Locates)
Filtering for Specific Work
Sod Damage Map
Performance Measures
Consistent Data One Answer, Not Three
Retrieving Data Through Reports
Access to Historical Data • • Interlocal Agreements Accident Reimbursements Cost Justification FEMA Reimbursement
Example: Annual Traffic Signal Maintenance Costs
Accident Damage Work Order – Results In……. .
Itemized Billing to Responsible Party
Work Order for Special Events – Results In….
Cost Justification
Tracking Costs for FEMA
Example: FEMA Staff Hours Report (One of Many Reports)
For Any System: GIS What to Look For How to Integrate
GIS
What to Look For (Generally) Technology Platform Communication – Users, Customers Integration – Out of the box, or custom Scalability – Size of data store, number of users • Licensing – Per seat, per floating seat, per site. • •
Integration • • Open systems. Common platforms. Data dictionaries for each system’s database. Focus on the data (what you don’t see) not on the data editors (what you do).
