Videnrepræsentationer i byggeprocessen
Knowledge representations in the building process
IT i Civilingeniørspeciale i Byggeledelse/IT in Building Management. 2007
1. Background
[goto top]
Udviklingen indenfor ICT de seneste årtier har indebåret øget pres på at civilingeniørers må tilegne sig ny viden for at kunne deltage aktivt i specifikation, design, implementering og evaluering af digitale informationscontainere som bruges til lagring af byggeprodukt- og byggeprocesmodeller. Det igangværende paradigmeskift fra papirbundet til digital kommunikation har vidtgående konsekvenser for vores positionering og overlevelse i det globale samfund og kræver både dyb og bred kunnen indenfor flere basale og delvis nye videndomæner.
Since the introduction of the world wide web (WWW) and standardisation of Internet services and communication protocols we can see a huge shift in the way we communicate, collaborate and handle digital knowledge. The semester 7 course focuses on models and representations of building products and processes. (In the semester 8 course we take an end user perspective on how ICT tools can support collaboration, communication and access to Internet based computer resources.)
The anticipated ICT tools are only partly developed and must be designed tested and implemented in close collaboration with the building process end users. This requires that civil engineers get a deeper understanding of some knowledge domains that up till now only has been partly covered in the civil engineering curricula.
The ICT will strongly influence how we take advantage of and interact with the computer resources
- information storage and interaction media will be more separated (paper is both)
- it will be easier to adapt information containers to user needs and usage context (meta data, models interoperability, model access, etc.)
- buildings and building processes will be more effectively and efficiently represented in digital models with different knowledge representations.
- the web will form the infrastructure for information container access, and application communication
- human collaboration, team work and communication modes will be developed and partly changed
- collaboration work spaces will get a added virtual dimension being less dependent of the physical room.
The mutual influence between practice and ICT progress is necessary to maintain. Civil engineers must posses both general and some specialised ICT related knowledge to be able to specify and participate in the development of new ICT tools and to be pro-active in the process of changing work routines and company and project organisation.
This course aims at providing general knowledge on how
present and future digital product and process models can be designed and implemented as well as deeper knowledge in certain key areas such as conceptual modelling methods, different knowledge representation propereties, web-database integration, the semantic web, and model integration.

2. Goal
[goto top]
Den studerende skal opnå viden om grundlæggende koncepter, teknologier og metoder til at analysere og udvikle modeller som beskriver en bygnings funktionelle systemer, processer i byggeriet samt modeller for videnhåndtering på World Wide Web.
Den studerende skal ved den afsluttende prøve kunne:
- Beskrive hvordan processer og produkter i den virkelige verden kan beskrives som modeller der kan implementeres i IKT-støttede systemer
- Kende til hvornår forskellige konceptuelle modelleringsmetoder kan bruges
- Kende principperne og metoder for etablering af web-database kobling.
- Kende forskellige videnrepræsentationers egenskaber og disses egnethed til modellering af forskellige systemer med specielt fokus på relationsdatabaser, hypertekst og regelbaserede repræsentationer.
- Kendskab til Service Oriented Architectures til understøttelse af systeminteroperabilitet og adgang til brugerservices
- Kende principper for og opbygning af Semantic Web baserede repræsentationer inklusive kendskab til Extensible Stylesheet Language Family, XSL.

5. Learning Material
[goto top]
The course content is delivered through the lectures, reading of literatur , and exercises/miniproject. It is impossible to find a set of literature that covers the course content completely. The lectures are supported by lecture slides available on the course web site. The slides with emphasized titles in the navigation bar has the same status as course literature (though not eventual references on the slide).
References to further reading is found in the lecture notes.
The coarse literature consists of both Lecture Slides and literature according to the list below.
The 'IT in Civil Engineering' site (http://it.civil.auc.dk/) also gives access to
previous years courses and if applicable mini projects. You reach it from the top of this page.
5.1 Lectures
[goto top]
The lectures are accessed from the lecture scheme below.
Each lecture has a easy to navigate slide bar and an opening slide with
short content description, questions for self assessment, references to the literature according to the literure list below and proposals for further reading.
The four hour lecture/exercise followes the scheme
- 2 hour lecture
- 1.5 hour exercise in group
- 0.5 hours exercise results presentation and follow discussions
5.2 Exercises/Mini-project
[goto top]
The exercies are also accessed from the lecture scheme below. Student group exercises results are continously updated
The exercices may well take use cases from the ongoing semester project or even be contained in a mini-project defined by the group.
The following domains will be covered during the exercices
- Write scenario(s) of the future ICT supported building process
- Conceptual modelling of your semester 7 project
- Database design and web access
- Knowledge representations

World-Models-Systems
We explain some basic concepts and make definitions; systems, ontologies, conceptual models, data models, ICT, Building Information Models BIM, IDM, IFC Model views, and classifications.
Why and how ICT have been introduced in the building processes during the
latest decades (building processes, ICT system examples and properties, development driving forces, virtual organisations).
Building product and process models are explained and exemplified as well as
relevant knowledge management issues including new ways to handle information containers in local to global networks.

Relational Databases modelling and WWW access.
Relational databases is and will be an very important information container
for building process and product information.
We will learn how to design and imnplement a relational database as well as
learn about the principles and methods behind connecting databases to web browsers.

THE SEMANTIC WEB
These two lectures and exercises deals with the nex generation
knowledge representations in form of hypertext on the WWW, namely
Semantic Web.
"The Semantic Web is an extension of the current web in which information is given well-defined meaning, better enabling computers and people to work in cooperation."

10. THE DIGITAL CITY AND SOCIETY.
THE INTELLIGENT BUILDING
Information technology,IT, will cause a paradigm shift in
our society from the art of writing, printing to the art
of communication.
In the same way as the car highly influenced the physical
design of our society IT will higly influence the forming
of the global villages.
We will investigate exisiting and expected infrastructures,
systems, and services in the intelligent buildings and digital cities,
and how they can be designed, modelled, and implemented.
