Using Flexibility to Increase Value

in Transportation Systems Planning

MIT Professor Richard de Neufville

Engineering Systems + Civil and Environmental Engineering

Author: Flexibility in Engineering Design MIT Press, 2011

Theme for Flexibility

Paradigm change in project evaluation, choice • From: standard Net Present Values (VPN),

ignoring risks (as done by World Bank) • To: recognizing actual uncertainties and

planning for adaptation to real situations!

Flexibility => significant increase in value

• Using a win-win approach

• Mitigates risk (downside) -- a win

• Opens opportunities (upside) – more win


Outline of Presentation

1. Discussion of Standard Evaluation

Procedure for Transportation projects,

Engineering Systems in general

2. Flaw of Averages

3. Concept of Alternative Paradigm

4. Example Application in Bogota


Standard Evaluation Procedure

for Transportation projects,

Engineering Systems in general


Standard Evaluation Procedure

1. Make a forecast

2. Evaluate alternatives using forecast,

finding a unique cash flow

3. Calculate Net Present Value (VPN)

or equivalent such as IRR

HOWEVER:

• Future is Uncertain, as are outcomes

THEREFORE:

• Above calculations are misleading!


The Flaw of Averages


Flaw of Averages

Named by Sam Savage (“Flaw of Averages,

Wiley, New York, 2009)

It is a pun. It integrates two concepts:

• A mistake => a “flaw”

• The concept of the “law of averages”, that

that things balance out “on average”

• Flaw consists of assuming that evaluation

based on “average” or “most likely”

conditions give correct answers NOT SO!


In Words

• Average of all the possible outcomes

associated with uncertain parameters,

• does not equal (except if system linear)

• the value obtained from using the

average value of the parameters



Practical Consequences

• Unless you work with distribution, your

evaluation gives wrong result –

• and wrong results lead to wrong ranking

and choice of design

• design from a realistic description differs – often

greatly – from design from average description

• This is because gains when things do well, do

not balance losses when things do not

(sometimes they’re more, sometimes less)


Concept

of

Alternative Paradigm


New, Flexible Approach to Design

• Recognizes Uncertainty

• Analyses Possible Outcomes of Designs

• Chooses Flexible Designs to

– Reduce, eliminate downside risks (in general,

less ambitious initial projects – less to lose)

– Maximize Upside opportunities (that can

expand or change function, when, if, and how

seems desirable given future circumstances)

Great Increases in Expected Value Routine!


Great increase in Expected Value

• systems with flexibility to adapt to new conditions can greatly increase expected value.

• With flexibility we can

– avoid future downside risks (by building smaller with confidence that can expand as needed)

– profit from new opportunities by appropriate actions

• Reduce initial capital expenditure (CAPEX). – Lower initial CAPEX because less complex at start

– Lower Present Values, because costs deferred many years (and maybe even avoided)

Higher returns, lower cost = A Great Formula


HCSC Building in Chicago

• In 2007-2009, 3000 people were coming to work

in the 30-story HCSC building in Chicago,

• … and a 27-story addition was being built right

on top of them!

• The structure was designed in 1990s with extra

steel, utilities, elevator shafts, etc. to permit

doubling of height.

• This flexibility was exploited a decade later


Here’s the Picture

Vertical Expansion of Health Care Service Corporation Building, Chicago.

Phase 1 (left) and Phase 2 (right) in center of image.

Source: Goettsch Partners, 2008 and Pearson and Wittels, 2008.


The Paradox

• 30-story building with capacity to expand – costs more than one without expansion capacity

– Yet saves money!

• Why is this?

• The fair comparison is between – 30-story expandable building and

– what HCSC would build otherwise to meet its long-term needs – such as a 40-story building

• Flexible design saves money 2 ways: – Lower initial Capital Expenditures (CAPEX)

– Deferral, possible avoidance, of expansion costs


Example Application:

Public Transport in Bogota

To BRT or HRT in Bogotá?

That is the Question

Summary

1. Standard Evaluation Procedure for

Transportation projects, Engineering

Systems in general, is FLAWED

2. It fails to recognize, deal with risks

3. Flexibility is New Alternative Paradigm

4. Helps planners deal proactively with risk:

Reduces exposure to downside;

Allows for dealing with upside

Investment


Total Public Private

Private investments need to grow from about 1 percent of GDP to between 2.5 and 3 percent to close the infrastructure gap, which represents some 100,000 million dollars a year.


The “new” problem: Urbanization

5. Conclusions & Challenges

Latin America needs to improve its transport infrastructure and direct its efforts towards integration

Improving the region’s infrastructure needs a stronger participation from both the public and private sector

Parallel and collaborative efforts from the public and private sectors are necessary in the following areas: Extension and maintenance

of road network

Performance of freight transport by road

Ports

Freight railways

Trade facilitation and border controls

Support for better logistics’ management in small and medium-size businesses

5. Conclusions & Challenges

Consistence and continuity in national policy formulation is key to enhance effective interventions

Multilaterals play an important role in adding value with knowledge sharing and project specific learned lessons
