Asset Management
Control of assets
Assignment of responsibility
Maintenance of inventory
Disposition
Maintenance in a State-of-Good Repair (SGR)
Ensure that assets used economically throughout their useful life
WorldBank 5
What is SGR?
Assets renewed/replaced when needed
Renewed at critical midlife points to ensure full useful life
e.g.,
Buses 8 years
Busways 8 years
Roofs 20 years
Track 25 years
Replaced at the end of their useful lives
e.g.,
Buses 15 years
Rail cars 35 years
Bridges 50 years

SGR Database Is Needed
Identify renewal/replacement activities Important for often-forgotten renewals
Demonstrate ongoing funding needs and consequences Engineering assessment of current assets
Support long-range capital planning Project programming under constrained
funding

Ages of assets range up to 100 years
Service expansion continues

Boston SGR Model Approach
Focus on high-cost assets Not a maintenance database of all assets
Support periodic data updates A dynamic, not static problem
However, staff and resources limited
Provide objective analysis Uniform criteria and process
Report consequences
WorldBank 13
SGR Database — Assets Table
Stores information about all key MBTA assets
Vehicles
Facilities
Systems
WorldBank 14
Asset Table Attributes
“Condition” Measures
Age

Project “Action” Costs

Contingency Factors

Operational Impact Scoring
0/1 Scoring Depending on “Operations Criticality”
Examples of Critical Projects (Score = 20)
Buses, Track, Signals, Power
Examples of Non-Critical Projects (Score = 0)
Stations, Parking
WorldBank 19
Cost-Effectiveness Scoring
Cost-Effectiveness (CE) = Daily Riders/Project Cost
Project Cost = Remaining Cost for Multiple-Year Funded Projects
Project Score = (Project CE / Ave CE (All Projects)
* 10
Subject to Maximum Score = 20
WorldBank 20
Sequential Programming Process
Identify candidate projects Actions come due
Delayed projects from prior years
Score and rank projects
Fund projects in rank order until:Cost (project i) > Funds remaining
Mark unfunded projects as candidates for next year
Carryover remaining funds to next year
WorldBank 21
Analysis Questions
What is the funding needed to bring and maintain system at SGR?
Lives of all assets < services lives
All renewals performed on-time
What are the consequences of providing less than required SGR funding?
Replacements/Renewals performed on-time
Replacements/Renewals delayed
Replacements/Renewals not performed
WorldBank 22
Unconstrained Funding Analysis
Simulates effect of unlimited funds applied to capital needs
Determines:
Minimum time and funds needed to achieve SGR
“Reduce the Backlog”
Funds required to maintain the system at SGR
Baseline comparison for other funding scenarios

Constrained Funding Analysis
Simulates effect of limited funds applied to capital needs
Limited funds < Funds needed to achieve SGR
Determines:
Beginning/Ending Period Comparisons
Changes in Backlog
Percent of Assets > Service Life by Asset Type
20-Year Totals
SGR Needs Funded On-time, Late, Not at All

Discussions with Policy Makers
Internal Management
WorldBank 34
Discussions with Policy Makers
Briefing the Board of Directors on SGR
Convincing the Chairman to pursue SGR
Persuading the Legislature of need for SGR capital funding
WorldBank 35
