Asset Management as a Process Workshop Photo Session A: Inventory, Level of Service and Condition Assessment 2016 APWA Washington Puyallup, Washington Bryan Chappell, Water Quality Supervisor 1 About Pierce County 2 1
Pierce County s 8 Elements of Assessment Management Large initial investment Field and office resource activity Work must integratethrough hardware/software systems Condition Assessment Available Information Primarily ADT, population info Performance Measures Eight Elements of Asset Management Cost Data Payroll and/or cost accounting system Procedures, metrics, business rules housed in your manuals and CMMS system Replacement Model 3 Inventory Performance Measures Condition Assessment Eight Elements of Asset Management Cost Data Inventory The first step in managing your assets is knowing what you have and where it s located. If you maintain, operate, or preserve an asset, information about it should be in your inventory. Replacement Model 4 2
Inventory 1999 ESA Scare With support from upper management, Public Works assembled the equipment and resources Road Operations spearheaded the workflow process. Road Operations, Surface Water Management, GIS teamed up to create an SOP and collected all drainage features (public and private) 3 teams of 3 for 3 years (1999-2002) (198,000 features collected) 2 teams of 1 for maintenance of database and collection of new developments and found assets (2003 to current) 5 Inventory The collection team creates an AGO map of the locations that need to be mapped Locations come from: Assessment Teams New Developments PW Projects 6 3
Inventory Inventory Information Assets are collected using the Trimble data logger or an IPad Attribute information is stored as the features is collected Location is stored with the data logger or IPad s geospatial functionality 7 Inventory Static Assets (Trimble) Public Unincorporated Drainage Inventory Stormwater Detention Vaults 22,600 total number of catch basins and manholes 50,000 segments of pipe for 550 miles 39,000 segments of channel for 1,150 miles 144 total number of Bioswales Numerous vaults, Storm Filters, media filter drains, hydrodynamic separators, channel weirs, filter strips, rain gardens and catch basins with FROP-T s and weirs 8 4
Inventory Dynamic Assets (IPAD) Roadside Mowing Public Roadside Inventory Shoulder work locations Roadside mowing locations Roadside brush cutting locations Obstructions Advantages No longer driving every road Soon to come Sweeping Ditching 9 Level of Service Performance Measures Condition Assessment Eight Elements of Asset Management Cost Data Level of Service Quality, quantity, reliability, functionality, cost, and regulations are factors which shape LOS.

Level of Service - Regulated All conditions assessments are done based on Maintenance Standards. Currently 120 Tasks. All Work Orders are performed to a Maintenance Standard. Purpose Target Assets Safety and Loss Prevention Job Hazard Analysis Special Hazards Required PPE Safety Data Sheets Equipment Environmental ESA and NPDES BMP s Permitting Design and Engineering Procedure Quality Control Inspection Currently being updated to a new format 11 Level of Service Regulated 40H 6 from IE to top of debris 60 % of Sump Full Washington State Department of Ecology (NPDES) Standard 12 from IE to top of debris Road Operations Service Standard 25 % of Sump Full Why a more strict LOS than currently regulated? Less Jet rodding Capturing more sediment in the CB before it gets to the pipe Cleaner system Less water over the roadway locations due to unmaintained system Less cleaning of Tanks / Vaults Out of the 52 tanks and 38 vaults we had to clean 11 and 0 in 2015 Less time per CB when cleaning makes up for the increase in CB s being cleaned 12 6
Level of Service The way we have always done it Everyone is Different Supervisors with different backgrounds tend to see work that needs to be done with that eye Many different ways to maintain a ditch. 13 Condition Assessment Condition Assessment Performance Measures Condition Assessment Eight Elements of Asset Management Cost Data Condition assessment provides a snap shot in time of the current physical state of an asset compared to the established LOS. Condition data over time tells a story about performance Must be Measureable!!! Replacement Model 14 7
Asset Condition Rating Scale per Function Standard Defect Severity A 0-3 None to low B 4-6 Moderate C 7-9 High Work Order Prioritization No Work Necessary No or tolerable defects;, no work warranted at this time Work Order Created Low to moderate priority; should be completed as competing priorities allow Work Order Created Moderate to high priority; should be completed as soon as practicable. Condition may affect another asset. Defect Extent 1,4,7 Single or Isolated (<10%) 2,5,8 Several or Sporadic (10-50%) 3,6,9 Predominant (50-100%) Performance Measures Provide understanding of asset condition in terms easily understood by the public: Very Good Condition Good Condition Fair Condition Poor Condition Urgent Work & Emergencies Emergencies are responded to immediately; emergency work orders are not created as part of an assessment rating process Key to our Rating scale is that we get the remedy for the work with a Severity and Extent of the defect 15 Condition Assessment Condition Criteria Shoulder Assessment Condition Criteria Gravel Shoulder Maintenance (32A) Condition A (0-3) Less than three inches deep by eight inches wide by four feet long. Condition B (4-6) More than three inches deep by eight inches wide by four feet long. Condition C (7-9) Same as Condition B, with secondary impact to another asset such as, but not limited to pavement edge break up, windrow, or shoulder material on pavement 16 8
Condition Assessment Condition Criteria CB Assessment Condition Criteria Sediment level (40H) 0 = No sediment in the basin Very Good 3 = Sediment greater than 12 from the lowest IE Good 6 = Sediment less than 12 from the lowest IE Fair 9= Sediment high enough it is in the pipe (or affecting another asset) Poor Structure Damage (40L) Lid Damage (40P) 17 Condition Assessment Catch Basin Data Verify attributes for feature if needed Work Orders by Function Code: Sediment Level (40H) Lid Damage (40P) Structure Damage (40L) WQFC Damage (Varies) Comment Codes: B2 -Unable to Locate C3 Private D4 - Mapping Needed G7 -Berm at CB H8 Socked M13 - Vehicle/Object Obstructing N14 - Traffic Control Needed 18 9
Condition Assessment Assessment Manuals All inspections are to follow the criteria in the Assessment Manuals Drainage Assessment Manual (107 pages) Contain the Equipment, Procedures and Guidelines, Perceived ROW Limits, Feature Descriptions, and Data Assessment Forms. 19 Condition Assessment - Teams Catch Basin Inspections consist of: Daily inspections with 4 teams of two Assigned work zones Forms filled out on IPAD Inspections performed with drainage manual criteria All inspectors and vactoroperators receive IDDE training before programs start and with the rest of the crew at their road shop. 20 10
Condition Assessment Tools ArcGIS Online (AGO) Edits and updates are pushed back in real-time Use Disconnected Offline Editing for out of service work areas Dashboards Using our rating system which gives us: Remedy Severity Extent How we have a spatial location of the work to be performed that can be seen on a mobile device 21 Condition Assessment Tools New Method Associated image available in real-time from mobile device 22 11
