2 Vera Technology Programme Information Networking in the Construction Process The target is to promote the implementation and use of IT and networks as the enabling technologies to re-engineer the construction process Development of the Construction Process Implementation of IT SYNERGY Life Cycle Information Management Efficient Use of the Information Networks Information Sharing 3/40 Information Sharing Problem The work is mainly done with computers but most of the information is still exchanged on paper, which causes non-valueadding work, friction, data losses and errors 4/40

3 Goal in the Future Information is shared in exploitable data format directly between different systems 5/40 6/40 and more problems Industry fragmentation (Source: Erkki Liikanen, Member of the European Commission, June 2000) 11 million jobs in 2 million companies 93 % of companies with less than 10 employees only 100 companies with more than 2000 employees Investments in development (Source: Gabor Bojar, CEO of Graphisoft, September 2000) Building Industry Value of production: CAD investments: Automobile Industry Value of production: CAD investments: $ 3.3 Trillion $ 1.0 Billion $ 1.0 Trillion $ 1.8 Billion

Integration of advanced technologies Task Support Task Integration Enterprise Integration Current Early Adoption Future Hans Bjornsson - CIFE, Stanford University 05/2000

9 Current project management tools in the web are more or less document management tools The best ones include also some process support The management tools for shared product models are still missing The need for advanced information management tools 18/40 and Engineering Processes Shared models can contain complex rules for behaviour and relations between objects Easy and cost efficient evaluation and simulation at any project stage requirement management through the process thermal, lighting and performance simulation more accurate cost estimation environmental evaluation Semi-automated design integration and code checking New service areas for designers/engineers LCA/LCC services Information maintenance FM services...

19 Business and Cultural Barriers The change to data sharing is not only technical - it is much more cultural New processes and tools supporting them Real partnering and sharing the benefits through the whole AEC/FM industry Now the investments and benefits don t often meet Sufficient ICT skills Eagan Report, 1998 UK (Sir John Eagan) Technology is only the tool sort out culture first Instead of construction technology - collaboration Redesign on computer not on the site! 37/40 Real Life Cycle View? Client s core business FM services Building process Pressure to change Change adaptation Where are the real benefits of information sharing and ebusiness? Construction 38/40
