1 Managing Assets and the Important Role of GIS and GPS Arthur Astarita, Water Resource Specialist

2 RCAP Network

3 Agenda Quick review of GPS and GIS Asset Management (What? & Why?) Concepts Inventory Attributes (condition, life, replacement cost) Reporting Opportunities Applying of GIS (Pitfalls) Tools (Pros / Cons)

4 Global Positioning System (GPS)

5 Improving GPS Accuracy Differential Correction

6 Geographic Information Systems

7 GIS vs. CAD Large geographic distribution of assets versus One general location with many assets.

8 Types of GIS software Freeware GIS Spreadsheet scatter plots using UTM data Google Earth / GRASS Low Cost GIS Manifold / Globalmapper High Cost GIS ESRI ArcMap MapInfo

9 Tools for Asset Management

10 What Assets? Roads / Sidewalks / Manholes / Culverts Vehicles / Machinery / Equipment Facilities (water, wastewater) Forest / Recreational areas / Trails Aquifers / Watersheds Computers / Radios / Power Grids

11 Why Do Asset Management? Asset replacement decisions based on best available information. Information to justify and explain cash needs

12 Balance Sheet Assets = Liabilities + Equity

13 Governmental Accounting Standards Board s Statement 34 (GASB 34) 1. Need a clean opinion from an auditor 2. Report value of infrastructure assets 3. Determine cost of deferred maintenance 4. Establishes a good credit rating

14 Capital Improvement Plan IMPROVEMENT Estimated Cost 2002 Estimated Improvement Date Estimated Cost in Year of Repair (using a 5% inflation) Estimated Impact on Each Account Yearly Rate Impact with a 30 year loan@4.75 % Turbidity Meters $12, $12,600 $59 $4 Replacing Filter Beds (every 10years replace 50% of bed) $30, $34,500 $161 $10 Repairing Albany Ave pipes(4000 feet at 100 per foot) $400, $500,000 $2,336 $146 Storage Bldg. (Refurbish Old Fire Station or Add on to Monitor Bldg.) $40, $54,000 $252 $16 Replace Water Pumps $15, $21,000 $98 $6 Recoating the Inside of Water Storage Tank $40, $64,000 $299 $19 Replacing Roof of Filter Bldg. $35, $59,500 $278 $17 TOTALS $572,000 $745,600 $3,484 $218.10

15 Fiduciary duties a person to whom property or power is entrusted for the benefit of another The primary responsibility falls on operators, the board of directors and local regulatory officials.

16 Assets are not Consumed, They are to be sustained to provide the highest service level.

17 Performance Manage Performance Levels Initial Design Capacity Minimal Performance Level Management Management Zone Zone Time

18 Performance P to F Interval Monitoring P-Performance X P1- Vibration X X P2-Oil X P3-Audible Noise Management Zone X P4-Tactical Heat Time X F-Failure

19 Core Asset Mgmt Questions 1. What is the current state of my Assets? 2. What is my required sustained Level of Service? 3. Which assets are critical for performance? 4. What are the best CIP and O&M strategies? 5. Given the above, what is my best funding strategy?

20 How Assets Fail

21 art art art Vulnerability Assessment Asset Inventory Asset Mgmt Asset Use Emergency Response Plans GASB 34 Sanitary Survey WARN Comprehensive Planning Implementation

22 Asset Management Mantra 1. Inventory 2. Prioritize 3. Plan 4. Implement 5. Review & revise

23 Inventory What? Where? Condition? Life? Value?

24 Too General. Must Itemize. Separate Columns for name and Model # Subjective. Should Quantify Excel is limits details and sorting

27 Inventory Use All Sources to Identify Every Asset As-built drawings and Design plans Operation and Maintenance Manuals Maintenance records Capital Improvement Plans Comprehensive Performance Evaluations Staff knowledge

28 Inventory Asset Attributes Accurately Describe Asset (M&Ms) Asset Condition Useful Life Installation Date Current cost to replace ENERGY CONSUMPTION kwh/yr

29 Asset Inventory Group Skull Sessions (Standardize names) Data Gathering (Assign Teams) QC/QA (Abbreviations, spelling) Data Entry (Knowledgeable Team) QC/QA (All Team Reviews) Distribution (Security) Updates (Bi-annual reviews)

59 GIS Issues for Small Towns 1. Requires specialized equipment, training 2. GIS is compartmentalized 3. No immediate return on investment 4. Too Costly for small government 5. No need for data integration 6. Confidentiality

60 Specialized Designed for desktop use Computer power less costly & more available User Friendly Drop down menus Point and click File sharing Web-based GIS available

61 Compartmentalized Collaboration between departments can form: Planning Public works Tax assessor Code enforcement Finance Data and mapping are related Visualization for officials and citizens

62 Immediate Return on Investment Data already exists on State and Federal sites Prior engineering contracts Parcel maps already exists* Analysis of current and future land use Dependent upon data collected, qualified and, entered

63 Too Costly Pool resources over all town departments Form Coalitions with other area towns Create programs for local college interns Emergency mgmt & homeland security $

64 Need for Data Integration Practicalities for most local governments Overcome silo departments Promote efficiencies between departments Land valuations Ordinance enforcement Budget forecasting
