Introduction to Asset Management

Gordon Sparks, Ph.D.

Professor Emeritus, Civil Engineering University of Saskatchewan Technical Advisor, AM-SK

What is Asset Management?

Infrastructure Asset Management :

• Is Asset Management focusing
• n infrastructure, rather than financial assets.
• Asset Class for todays discussion - Bridges

 Infrastructure Asset Management is: The planning related to determining what

is required in terms of activities and costs to:

Create Operate Maintain Renew, and Dispose,

Of a infrastructure asset so it provides the Desired Level of Service.

A Lifecycle Forecast for Infrastructure Assets includes activities & Costs related to: – Create – Operate – Maintain – Renew – Dispose

An Asset Management Plan:

 “Documents”  Life Cycle Activities & Costs required

so they provide the “Desired Level of Service”

The Asset Management Plan:

• Provides the “Information” required for:
• “Informed Discussions”
• Which leads to:
• “Informed Decisions”

What We Cannot Do!

• The Long Term Financial Plan will also identify what

infrastructure / services we do not currently have enough funding to sustain at the desired standard going forward

Managing the Risks

Are present funding levels sufficient to continue to manage risks in the medium term? The main risks and consequences are for example:

• extreme weather events
• flooding
• ???

1.7 Asset Management Systems

are a combination of:

• Information / Technology / Software
• Financial Accounting
• Asset Register
• Analysis
• Life Cycle Costing
• Teams
• Administration
• Finance
• Public Works
• Political Leaders

Monitoring and Improvement Program

• Formally develop and implement a Continuous

Improvement Plan for Asset Management.

• Review and update the asset useful lives and current

replacement costs in the Asset Register.

• Develop a Plan for Capital Renewals and Upgrades.
• Review Risks and Develop a Risk Management Plan.
• Develop Customer and Technical Levels of Service.

Topic of Today’s Discussion:

• Developing Asset Management Plans

for Rural Bridges

Challenge:

 1468 Rural Bridges  Predominately Treated Timber structures 85.6% Timber (1256) 7.8% concrete (114) 6.6% Steel/concrete (98)  Useful Service Life Highly Variable Assume - 50 to 60 years

Rural Bridges - Saskatchewan

Roads Class 5 and Better – Bridges Restricted

Roads Class 5 and Better – Bridges Poor

Roads Class 5 and Better – Bridges Fair

Roads Class 5 and Better – Bridges Good

Road Classes 6 & 7 – Bridges Fair, Poor, Restricted

So Major Challenge:

• the “Sustainability” of the Rural Bridges!

So “what” Could & Should be Done!

• Clear need for an
• Asset Management Plan for Rural Bridges

Cost to Replace a Rural Bridge

 Range from $300,000 - $1,300,000  Assuming average $600K  145 bridges 70+ years - $87 million to replace  488 bridges 60+ years - $292 million to replace  771 bridges 50+ years - $421 million to replace

Current Rate of Bridge Replacement

• in the order of 5 bridges/yr.
• 5 x $600,000 = $3 million/yr.

• Conclusion:
• Rural Bridges are not “sustainable” at

current funding level of $3 million/yr.

Options:

• Access more funding to sustain All Bridges
• All Road Classes
• 488 bridges 60+ yrs

replaced over 10 yrs = 50 Bridges/yr.

• 50 x $600,000 Bridge = $30 million/yr.

 Minimal Option: Priority/Focus on Timber Bridges on Class 5+ Roads Restrict & Close Bridges on Class 6 &7 Roads as

required with time.

“Minimal Option” – not acceptable – but order of

magnitude of absolute minimum funding required “Going Forward”.

Class 5+ - 339 Treated Timber Bridges

130 Bridges built 1962 – 1971 therefore 47 to 56

• yrs. old

Assuming 130 Bridges replaced over next 10

years = 13 Bridges /yr.

Average Cost/ Bridge on Class 5+ =

$800,000/bridge

13 Bridges/yr. x $800,000 = $10.4 million/yr. $10.4 million/yr. – Minimal Option

 Summary

• Current Funding for Rural Bridge - 5 bridges/ yr.

$3 million/ yr.

• replacement rate – Bridges unsustainable!
• Funding Level Required to Sustain All Bridges on all Class of

Roads

• 50 Bridges/yr.
• $30 million/yr
• Minimal Funding – Sustain only Bridges on Class 5+ Roads
• 13 Bridges per yr.
• $10.4 million/yr.

What Is Required?

 Develop “Credible” Asset Management Plan for all

Bridges.

 Address the question: Are there bridges that are “no longer” needed

going forward?

Are there bridges that the “costs” for the

service provided can not be justified?

Another Issue:

 How is “Inter – Generational Equity” going to be

addressed?

Those using the bridges over the next 50 years should

each pay their share.

Folks today should not have to bear the financial

burden of the cost of replacing a bridge that will serve folks for the next 50+ years.

Option – Finance the Bridge over Time Going Forward

Cost to Replace a Bridge – Annualized

• $600,000 at 4% over 50 years
• Annual Cost (A/P

,I,N) = $600,000 x (A/$600,000, 4%, 50yrs) = $600,000 x .04655 = $27,930/yr

$600,000 at 3% 0ver 50 years = $600,000 x .03887 = $23,322/yr

• $600,000 at 2% over 50 years

= $600,000 x .03182 = $19,092/yr

Summary

The Capital Costs of $600,000 for a Bridge  Translates into in the order of $24,000/yr. $2000/month/bridge! Capital Costs only

Costs in the order $2000/month per Bridge = $2000/month / 30 days/month = $67/day Average Daily Traffic = 10 vehicles =$6.70/vehicle

Vehicles/day (ADT) Cost/vehicle/crossing 10 = $6.70/vehicle 20 = $3.35/vehicle 40 = $1.67/vehicle 50 = $1.34/vehicle 100 = $.67/vehicle

So Major Challenge:

• regarding the “Sustainability” of the Rural Bridges!

So “what” Could & Should be Done!

1) Need for a “Transportation Network Plan”

to determine:

• Which Bridges are “Required” Going Forward?
• Which Bridges can be “decommissioned”?
• Economic considerations
• Social considerations

2) Asset Management Plans for all Bridges

Example: Transporation Network Plan

2 Mile Detour 2 Cars x 2 miles x $.60/mile = $2.40/day 1 Truck/day x 2 miles x $1/mile = $2.00/day Total $4.40/day x 365 days/yr = $1606/year $150,000 to replace bridge – 75 yr Life = $2000/yr at 0% 2 Cars 1 Truck / Day

2) Asset Management Plans for All Bridges

Life Cycle Costs

Foundation of Asset Management Plans:

Asset Registers

An inventory of infrastructure assets

Asset Register: Excel Spreadsheet

Year Constructed Useful Life Replacement Cost

Output: Asset Management Plan

An Asset Management Plan:

 “Documents” the information / data related to

infrastructure assets, and thus supports:

“Informed Discussions”, and “Informed Decisions”

Next Steps: Developing AMP For Bridges

 Build on Existing Bridge Inspection Program  Inspection Program – Assesses “Condition” of Bridges ever 3 years  Add development of Feasible “Maintenance, Repair, Rehabilitation,

Replace, Decommission, Alternatives for each Bridge.

 Add “Life Cycle Costing Analysis” of M &R etc. Alternatives for each

Bridge and select a “Costs/Effective” M & R etc. Strategy for each Bridge – document in Asset Management Plans for each Bridge.

 Integrate individual AMP’s for each Bridge together into a “Bridge

Network Management Plan & Long Term Financial Plan”.

1) Transportation Network Plan 2) Asset Management Plans for each Bridge. 3) Bridge Network Management Plan & Long Term Finance Plan Will Support:

“Informed Discussions”, and “Informed Decisions”

Maximize “Back for the Buck”!
