Agenda Adaptive Capital Planning Winston-Salem’s Adaptive CIP Overview of the Master Plan Goals for Developing the iCIP Tool How the iCIP Tool Works

Adaptive capital planning

Adaptive Capital Planning Focus on Asset Management & Optimization rather than Expansion Need for cost-effective assessments Address worst condition assets first Risk based prioritization Planning for Growth alongside of Budgeting for Maintenance

CIP Prioritization - Old approach Traditional CIP Static CIP Report Time and situation constrained Not risk-based Not adaptable Adaptive Capital planning

Factors that can affect Planning Growth Rates Asset Condition Outside Factors Pictures for final presentation? Maybe cycle through

Winston-Salem’s Wastewater System Master Plan

City/County Utilities Commission – Collection System Overview 1,724 miles of sewer main 49 Pump Stations Two Treatment Plants Muddy Creek (21 MGD) Elledge (30 MGD) Three Major Sewer Basins 9

Wastewater System Master Plan Evaluate collection system capacity in three major basins Prioritize Capacity improvements 30 year Master Plan (2011 – 2041) Future Treatment Alternatives Evaluation Collection System Asset Evaluation Wastewater System Evaluation Capacity Driven Projects Condition Driven Projects CIP Projects 10

Developing the cip Projects Capacity Driven Projects Flow Projections Field Surveys and Flow Monitoring Hydraulic Model for Base and future Years Condition Driven Projects Facility Inspections Pipeline Prioritization Criticality Ratings based on consequence of failure Condition Scores evaluated based on available data, modeling results, and age of pipe

Asset Management approach to system planning Provides a comprehensive and coordinated Master Plan CIP

…But How final is the “final” CIP? What if… A routine pipeline inspection reveals a pipe failure at the location of a future capacity project? OR A 2020 DOT project includes tearing up and repaving the road at a sewer crossing in the 2030 CIP. Does it make sense to move forward the project? All of the project or maybe just the road crossing? We need to compare alternatives and update the CIP!

Adapting the cip using the iCIP tool

Customizing iCIP for Winston-Salem Evaluating Current Needs Critical Capacity Driven Projects Long-Term and Short-Term Budgeting Tools Increased functionality for Cost Estimating, Project Scheduling, and Cash Flow and Spend Plans Data Collection Plan Evaluating Future Needs Asset Condition Database Prioritize Inspection and R&R budgets 15

Adaptive approach to CIP Prioritization Three Components Asset Prioritization – Leverage GIS Inventory and updated condition data to prioritize projects (GIS) Asset Costing – Dynamic update costs based on project changes to scope and schedule (Excel) CIP project identification (iCIP)

iCIP - GIS interactive Capital Improvement Planning Built on top of ArcGIS (Esri Add-in) Open architecture, Esri-based enhanced by B&V Integrate CIP with existing GIS Inventory Risk and Capacity Based Prioritization iCIP Cost estimating tool Elevate awareness with graphic displays Risk- and capacity-based prioritization Integrate with existing GIS asset inventory Geographic interface Adapt to changing budgets and priorities Dynamic budgeting and reporting 18 18

Adjusting cash flow

Adaptive CIP An Adaptive CIP can… Leverage risk-based prioritization and/or capacity assessments Immediately see results of decisions graphically Easily integrate with existing and updated GIS asset inventory Provide tools to adapt to changing budgets, asset conditions and priorities 28

In closing… An Adaptive CIP can respond to… Growth – Whether a recession slows growth or a housing boom in an unforeseen area accelerates growth, CIP projects can “slide” to when they are needed. Condition – Prioritization scores can be continually updated and used to allocate resources efficiently Outside Factors – Updates can be made to take advantage of developer projects, transportation projects, etc 29
