1. The integrated building process Information structures
Facilitate for an uncomplicated and efficiant transfer of information between actors and processes and phases during the building process and through the whole life cycle of the building or the civil engineering work

2. From classification tables to object/class/reference libraries
Started as a review of the existing classification tables.
Starting point:
Need for structuring of information in the facility management phase - life cycle thinking
Need for reuse of information from the construction phase to the management phase
Parallell with participation in ISO, ICIS, IAI etc.

6. From classification tables to object/class/reference libraries
Classification tables are built on static hierarchies normally made for a special and limited purpose
No connection between the different tables
Does not establish a common understanding of all built objects
Does not necessarily function for new purposes
Not computer sensible
Does not cover everything, especially regarding properties
Conservative - experiences are connected to the existing tables

14. From classification tables to object/class/reference libraries
We need a computer sensible library of all built objects
We need a framework for object oriented information where all those information elements are referenced to each other - integrated
A development towards an electronic model which will contain all information from “bubble” to grave.
Project documents will be snapshots of this model at a given time
A parallel movement among people engaged in structuring of information

1 Study
Find out what has been done
Understand principles for product modelling
Understand different product models
Understand the evolution which has been going on
(Avoid doing things twice)
2 Testing and developing
Test the most promising existing solutions with a typical built object
(The wall test case)
Test their ability to changes
Do necessary changes and development
3 Conclusions
