 In a manufacturing/distribution
supply chain, inventory is the
embodiment of bad information

 In the building design and
construction supply chain, the cost of
bad information is embodied in:






Add/deduct alternates; Allowances
RFIs, Addenda, Sketches
Change Orders, Substitutions
Material stored on site
Contingencies, Retainage
Litigation

 Estimates such as the Egan Report in
the UK, put the cost of bad
information in construction as high as
30% cost of project cost

 A/E fees @6%±
 GC general conditions +profit ~6%±
 Owners pay ~12% of construction
cost for creation and management of
information, yet 30% of construction
$ are wasted due to bad information
 IOW, for every $1 owners pay for
building information, $2.5 are wasted

 Is interoperability the answer?

 Interoperability is a business strategy,
like any other – not a natural law
© Copyright 2008, Jerry Laiserin
All rights reserved.
 Market-leading companies with large
ecosystems of third-party developers
and other partners may not “need”
interoperability

 “Information Rules”
 Shapiro and Varian
 Market leader never wants to fight a
standards war
 “Blown to Bits”
 Evans and Wurster
 Richness versus reach

 Phil Bernstein, Autodesk VP, quoted in
McGraw-Hill interoperability report,
January 2008: “The demand for
interoperable applications right now
exceeds our capacity to achieve it.”
 Phil Bernstein, previously, at AU and
elsewhere: “When there’s a market
demand [for IFCs] we’ll meet it.”

 Even a #2 player in a market prefers
to bask in the reflected glow of #1
 Avis/Hertz, Pepsi/Coke, BK/McD’s
 In a 2-horse race, the worst you can
finish is still second

 Brad Workman, Bentley VP, quoted in
McGraw-Hill interoperability report,
Jan08: “Now that we’re starting to
see adoption [of IFCs] we’re going to
have to do a better job of fulfilling it.”
 Bentley corporate marketing
previously blamed all interoperability
cost on “Autodesk business practices.”

 Interoperability has greater appeal to
players in the #3 spot and below

 E.g., Graphisoft (ArchiCAD) and
corporate parent Nemetschek have
been prime movers behind IFC,
arguably more consistently and more
aggressively than other CAD/BIM
vendors
 Irony is that Nemetschek now #2
worldwide, and ArchiCAD #2 in USA
BIM model-authoring usage

 Interoperability as a political and
economic/competitive strategy for the
EU and adjacent countries, especially
small countries wishing to preserve
high standards of living in a
globalized world – e.g., Finland,
Netherlands and Norway

 However, dissatisfaction with progress
on these urgent national goals
 Venting frustration on vendors and on
shortcomings of free-market solutions

Implementation of IFC compatible BIM

Norway, Sweden

 From the Executive Summary:
The IFC standard is generally agreed to be of
high quality and is widely implemented in
software. However, the certification process
allows poor quality implementations to be
certified and essentially renders the certified
software useless for any practical usage with
IFC. The IFD Library is also generally seen to
have the potential to solve many real world
problems. However no implementation support
in off the shelf software exists at the moment.

 Political Recommendations
Large public clients should be early adapters and
set proper demands in the market to drive the
implementation and development of buildingSMART
technology forward. Public authorities must follow
up with significant funding to ensure the proper
long term development and implementation speed.
We acknowledge that a free market approach will
not suffice to ensure the necessary open standards
based foundation. However, when sufficient
demand in the market is created, a free market
approach is desired for further development. This is
in agreement with similar earlier efforts, like the
development of the Internet

 Interoperability as a government
procurement strategy in a freemarket system

 USACE as exception
