2 Technology Program Information Networking in the Construction Process, Finnish national Construction IT Program by Tekes (National Technology Agency of Finland) Schedule - six years; Total volume Current budget 250 million FIM ($ 36 million) 45 % by Tekes 115 million FIM ($ 16 million) 55 % by the industry 135 million FIM ($ 20 million) Current situation Research projects: 35 / 20 million FIM ($ 3 million) Industrial projects: 80 / 160 million FIM ($ 22 million) Total: 115 / 180 million FIM ($ 25 million) Homepage 3/38 Current Problem The work is mainly done with computers but much of the information is still exchanged on paper, which causes non-valueadding work, friction, data losses and errors 4/38

3 Goal in the Future Information is shared in exploitable data format directly between different systems 5/38 6/38 and more problems Investments in development (Source: Gabor Bojar, CEO of Graphisoft in Stockholm on September 9th 2000) Building Industry Value of production: CAD investments: Automobile Industry Value of production: CAD investments: $ 3.2 Trillion $ 1.0 Billion $ 1.0 Trillion $ 1.8 Billion Fragmentation (European Union Figures) 11 million jobs and 2 million companies 93 % of companies with less than 10 employees only 100 companies with more than 2000 employees

21 Barriers to the Change 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 investments and benefits do not always meet sufficient IT skills a pre-study for the Vera program in showed that the lack of IT skills and know-how is the main barrier to the wider implementation of IT in the AEC/FM industry 41/38 42/38 New Business Concepts Drafting" information management paper document digital information traditional documents product models document a view of the model from a specified angle at a specified moment technical and juridical problems Environmental issues are coming more and more important Information will be produced for: decision making and production use and maintenance of buildings Minimizing the cost maximizing the added value through the whole building life cycle
