INTRODUCTION

PROJECT GOALS

2014 ESRI UC | City of San Diego Water Transmission Pipeline Condition Assessment | July 16, 2014

Identify critical pipes/segments

Prioritize pipes for inspections

Prioritize pipes for rehabilitation

Establish a defendable/repeatable process

4

SETTING THE FOUNDATION

Created 100’ Pipe Segments

Reconciled stationing

Created unique Pipe ID Numbering System for this project (yet maintained City’s FSN)

Kearny Mesa PotableCity’s original SPLASH GIS

After pipe segmentation

DATA MANAGEMENT PLAN

2014 ESRI UC | City of San Diego Water Transmission Pipeline Condition Assessment | July 16, 2014 27

Share results to engineers using ESRI’s ArcGIS Online

USEFUL TIPS

Develop consensus on proposed Risk Factors

Exporting CMMS data and historical information can be difficult, but worth the effort

ArcGIS Online is a very useful tool for encouraging user engagement with the data/results

Asset Management has many “pieces” but it is important to focus on “putting the pieces together” –resulting in a prioritized CIP!
