Introduction

  • PCA Paving Committee Meeting of August

26-27, 2013

  • Meeting focus on LCCA
  • There is a lot of hope that the use of LCCA

will open pavement markets

  • Consensus that project decisions should

not be made on first costs only

  • I continually hear a common statement

made about LCCA

ACPA - Applying Life-Cycle Cost Analysis (LCCA) in Pavement Selection - June 24, 2014

Introduction

  • Everybody knows that someone that is

good at life cycle cost analysis can adjust the inputs to justify an outcome

  • I agree.
  • I was a master of this in my former career

at the Wisconsin Department of Transportation

Did your father ever say to you?

  • Be careful what you ask for……,

you just might get it !!!

  • We don’t want to be in this position after

we have pushed hard for state agencies to use LCCA in the pavement type selection process

  • Coming back and saying we don’t like the

way you are doing it will be very unpopular

This workshop is about…..

  • Why should we do LCCA?
  • The major guiding principles
  • This presentation is about how do we do it

in Wisconsin

  • First a little history.

WisDOT 1993

  • WisDOT had been using some form of

LCCA since 1984 when federal regulations started requiring it.

  • Each project engineer did their design and

LCCA and chose pavement type with minimal review.

  • No real guidance was supplied on how to

do it.

  • Designers were supplied a spreadsheet

that did the thickness design and LCCA

SLIDE 8

WisDOT 1993

  • Results varied
  • Pavement selections were unpredictable
  • Paving industries were consistently

bringing debates to upper management on project selections

  • WisDOT managers were finding it difficult

to keep pavement quantities balanced in their “two healthy pavement industry concept policy”

WisDOT 1993

  • Maintaining competition within an industry

and between the industries was a core concept of then Secretary Ron Fiedler.

  • The order was given, “I want a pavement

selection process that is rational, predictable and defendable”.

  • “If both industries are happy you will have

done a great job, if both are unhappy you will have done a good job, if only one of them is happy, I will be unhappy”

WisDOT 1995

  • I completed the work in 1995 and

implemented the new policies

  • Still in force today
  • Basis of PCA Paving: New Realities report

ACPA - Applying Life-Cycle Cost Analysis (LCCA) in Pavement Selection - June 24, 2014

slide-12
SLIDE 12

So, what were our goals?

  • Rational – Good Engineering and Pavement

Management Principles

  • Predictable and Defendable – Good Policies in Place
  • This is not about individual projects
  • Rather this is about building pavement programs that are

sustainable year after year.

  • Our goal should be to have the project engineer

equipped with tools and policies such that he/she can do the pavement design, LCCA and selection, develop a concrete alternative for every project and select it when appropriate without ramifications or questions.

Critical Steps in the LCCA Process

  • 1. Develop structurally equivalent alternatives
  • 2. Develop pavement service life models for new

and rehabilitated pavements

  • 3. Select an analysis period
  • 4. Select a discount rate
  • 5. Estimate initial agency costs
  • 6. Estimate future agency costs and timing
  • 7. Estimate residual value
  • 8. Compare alternatives
  • 9. Determine best value alternative

ACPA - Applying Life-Cycle Cost Analysis (LCCA) in Pavement Selection - June 24, 2014

slide-14
SLIDE 14

Structurally Equivalent Alternatives

  • WisDOT long policy of AASHTO ‘72
  • WisDOT implementing MEPDG in 2014
  • Cities and counties –StreetPave
  • Non-equivalent designs can be too hard to
  • ver come in the LCCA due to the initial

cost only

  • Getting a concrete alternative and an

asphalt alternative is the key

  • The example of Fond du Lac, WI

ACPA - Applying Life-Cycle Cost Analysis (LCCA) in Pavement Selection - June 24, 2014

slide-15
SLIDE 15

Structurally Equivalent Alternatives

  • Known traffic, soils and materials
  • Good construction specifications and standards must be

part of this. – Base – Concrete mix – Joint spacing – Etc.

  • Design life and specifications must compliment each
  • ther
  • If they don’t, it is our responsibility to help them bring this

together.

  • WCPA Municipal Concrete Pavement Specification

Pavement Service Life Models

  • Are they managing their pavements?
  • Do they really know how long they last?
  • Does their maintenance and rehabilitation

procedures really extend the life as expected?

  • Quality of the model – all asphalt pavement

average being used interstate projects?

  • Pavement design life versus actual life
  • MEPDG is so critical in this effort.
  • The last time I built concrete…….

Analysis Period

  • Timeframe over which the alternative

strategies/treatments are compared.

  • Long enough to reflect significant

differences in performance

  • Must encompass the initial performance

period and at least one major rehabilitation

  • FHWA Policy Statement requires this
  • WisDOT policy requires a 50 year analysis

period

  • The same for all alternatives

Discount Rate

Common quote from Dr. Mark Wolfgram, former Administrator, Division of Investment Management, Wisconsin DOT

“Discount rates become a controversial issue in the life cycle cost analysis procedure when the policies surrounding the rest of the inputs into the analysis are weak”

SLIDE 27

Initial Agency Costs

  • The current world of information allows us to

capture the bid tabs

  • We know what they are paying for asphalt and

concrete pavements

  • We have the ability to debate use of inflated

prices or low ball prices in an LCCA

  • States, cities and counties are posting bid tabs
  • n their websites
  • Open records law

ACPA - Applying Life-Cycle Cost Analysis (LCCA) in Pavement Selection - June 24, 2014

slide-28
SLIDE 28

Initial Agency Costs

  • Costs should be based on history
  • Agencies spend significant resources on

developing engineering estimates and training staff how to do them

  • There is no one project so special that it

justifies departure from historic costs

  • WisDOT approach: county, surrounding

counties, region, statewide

  • Statewide average unit bid prices are not

allowed

ACPA - Applying Life-Cycle Cost Analysis (LCCA) in Pavement Selection - June 24, 2014

slide-29
SLIDE 29

Initial Agency Costs

  • Where there is no market:

– We use their asphalt cost data – This can work to our advantage initially – Several example cities in Wisconsin – We get them concrete data

  • Bid tabs from other agencies
  • WCPA policy on providing concrete paving cost

estimates

  • If we screw up and low ball the number, we

instantly lose the opportunity to do concrete again.

ACPA - Applying Life-Cycle Cost Analysis (LCCA) in Pavement Selection - June 24, 2014

slide-30
SLIDE 30

Future Agency Costs and Timing

  • This is a fundamental question
  • How does an agency maintain and

rehabilitate a pavement throughout the analysis period?

  • Agencies need to commit
  • Maintenance Departments need to track

costs by year and by roadway.

ACPA - Applying Life-Cycle Cost Analysis (LCCA) in Pavement Selection - June 24, 2014

slide-31
SLIDE 31

Future Agency Costs and Timing

  • State highway agencies typically have

these schedules and service lives in their planning and maintenance sections

  • Cities – sit them down and get them to

document and establish policy.

ACPA - Applying Life-Cycle Cost Analysis (LCCA) in Pavement Selection - June 24, 2014

slide-32
SLIDE 32

Future Agency Costs and Timing

  • Focus on historical and current costs of

asphalt or concrete

  • State agencies don’t have a crystal ball
  • Discount rate and present worth analysis

adjusts cost for the future

  • Agencies will debate cost adjustments due

to external forces (oil embargo)

  • Never appropriate to approach a single

project with a non traditional cost impact

  • Dowel bar example

Estimating Residual Value

  • Three ways to do this:

– Net value of the recycled materials (salvage value) – Remaining service life – Residual value as a support layer

  • Policy is required here, remaining service

life is the easiest and most widely used.

Life Cycle Costs

  • Commonly accepted tool for pavement
  • selection. FHWA and WisDOT regulations

and policies require it.

  • Professor William Holahan, Department of

Economics, University of Wisconsin- Milwaukee Paper

– Life cycle cost should be used by government – Net present worth analysis recommended – Assures the lowest possible property taxes

Life Cycle Cost Analysis (LCCA)

  • The decisions you make today effect the

City’s budget and resources of the future.

  • The decision you make today commits the

City for the life cycle.

  • Net present worth attempts to bring all

events into today’s dollars

  • Lowest life cycle cost assures low property

taxes
