models
ICT (Information and Communication Technology) may be defined as the technologies to
support capture, storage, manipulation, communication and delivery of information on
different application levels (from macro to micro scale) and in different contexts such as
technological, organisational, and cultural.

“Inadequate interoperability increases
the cost burden of construction
industry stakeholders and results in
missed opportunities that could create
significant benefits for the construction
industry and the public at large.
……
This report, prepared for NIST by RTI
International and the Logistic
Management Institute, estimates the
cost of inadequate interoperability in
the U.S. capital facilities industry to be
$15.8 billion per year. The intended
audiences are owners and operators
of capital facilities; design,
construction, operation and
maintenance, and other providers of
professional services in the capital
facilities industry; and public- and
private-sector research organizations
engaged in developing interoperability
solutions. “
15.8’’’ --> 1.8 milliarder DKK adjusted

Det Digitale Byggeriprograam -DDB
1/2
In 2002 the Danish national 'Digital Construction - a development
program for the whole construction sector' in Danish 'Det Digitale
Byggeri', DDB, was started. (40 millions DKK).
See also http://www.detdigitalebyggeri.dk.
As a result the public clients will 2007 state a set of ICT requirements
that the enterprises of the construction sector must meet if they wish to
tender for public construction projects.
An Advisory Board advises the National Agency for Enterprise and
Construction. EBST, on the overall direction and progress of the
development project. EBST also forms secretariat for the project,

DDB
2/2
Four projects were launched in 2003 within client requirements
formulation [i6 IT Civil Group participates in (2), (3), (4), and (5)].
(1) Digital tender
(2) 3D models
(3) Digital handover (Digital aflevering), DACaPo
(4) Projectweb
together with a project on
(5) Foundation for Digital Construction (classification and standardization
issues).
In 2005 the final project was launched namely
(6) Best Practice - or in Danish ‘Bedst i Byggeriet’
(7) Digital Projekplanlægning i renoveringssektorn (5 2005)

COMPETENCES NEEDS
Builders must process some ICT competences to be able to formulate needs,
requirements, and perform usability evaluation as well as to actively participate
in the (creative) design of tomorrows building process ICT tools.

World - system - model
3/4
The Virtual Building, VB, model is accessed
through more or less detailed representations.
The VB sub-models may be partly overlapping
and also contain redundant information.

Theory to Practice. Proceedings W78 22nd
Conference on Information Technology in Construction.

experience capture, design,
construction, use and re-design
of buildings.

4/4
The complexity and flexibility in
organization of the building process
leads to large difficulties to build up
highly formalized non-redundant
models except for certain more
standardized buildings and process
organization
The favorable degree of optimum
formalization of the building process
will be different dependent on which
actors view is applied.
There might be a negative correlation between
effectiveness and flexibility for different
representations.

Building Process Oscillations
Building Process models development have during the latest decades had periodic
focus on achieving a highly formalized non-redundant building product model, Virtual

Building Process in Change
ICT tools described into a building
process context. We envision
greater emphasis in the near future
on formalisation of building
process/product components
especially on the meta data level.
Formalised processes will more
efficiently handle flexible user
environments (UE) and project
information containers
accommodating partly redundant
information.

DEFINITIONS
ONTOLOGY
- the branch of metaphysics dealing with the nature of being
- An explicit formal specification of how to represent the objects,
concepts, and other entities that are assumed to exist in some area of
interest and the relationships that hold among them.
DICTIONARY
- a book that lists the words of a language in alphabetic order and gives
their meaning, or that gives equivalent words in different language.
CLASSIFICATION
- The action or process of classifying something according to shared
qualities or characteristics

COMPETENCES ….
There is at present and in the future building industry
a great need for persons who can take active part in
specification, design, implementation, and evaluation
of tomorrows building process support systems.
A broad view and insight into the complex building
process together with a broad and in some key areas
deep knowledge into existing and coming ICT tools
are required in combination.

[25/17]
A COMPLEX PROCESS
The implementation in the building process has been rather slow due to
- the building process is one of the most complex and less formalized applied
processes
- Building process actors using different ICT tools, languages and model
formalisms with a rich spectrum of user interfaces with different
characteristics
- A very cross scientific domain.
- Too little focus on building up it's own ICT competences (the out-sourcing
trend increases the risk of loosen company business strategic knowledge).
- Low client understanding that ICT pays back (better early decisions in
alternative solutions, higher quality and better documented end products.

HOW CAN I FOLLOW/INTERACT WITH
THE WORK?
The DDB program will end
in 2007.
A lot of what is presented
at this stage may (and will)
be revised both client
requirements and
classification schemes.
You are encouraged to
follow (both push and pull)
the discussions and
progress on the Learning
Net.
