3 Importance of the Built Environment Real Estate and Construction Cluster in Finland: Produces and maintains the built environment for business, services and living = one of the key resources of the economy Constitutes the main part, 70%, of the Finnish national assets Employs more than people = 20% of the work force Uses ~50% of the energy Operations 35 billion Interest 15 billion Total value of the forest 40 billion 10% Value of built environment 400 billion MOVING IDEAS INTO PRACTICE - March 21,

4 Productivity Problem In the last 40 years AEC industry has not been able to increase the productivity as the other industries USA MOVING IDEAS INTO PRACTICE - March 21,

6 Document/2D-based Process Information is still mostly exchanged as documents - often even on paper - which causes non-valueadding work, friction, data losses and errors MOVING IDEAS INTO PRACTICE - March 21,

7 Costs of Inadequate Interoperability Germany Savings of 670 million euros per year in manual work just by improving the quality of DXF data (Wolfgang Haas, Haas & Partner 1998) Finland Potential savings of 7% in the construction costs by efficient IT use. This estimation did not include savings in reducing errors with better information management, only direct work (Enkovaara & Heikkonen 1998) Several countries Removal of information re-keying would enable savings of 16% in the construction (Thomas Liebich & Jeffrey Wix, AEC3 1999) USA DOD uses $40 million per month in additional work because of the lack of standards. Since DOD s projects are 4% of the US market, this would translate into $12 billion per year in US (Dana Smith, DOD 1999) According to NIST s conservative estimate the lack of interoperability costs annually $15.8 billion to the U.S. capital facilities industry ( Cost Analysis of Inadequate Interoperability in the U.S. Capital Facilities Industry, NIST GCR , 2004) MOVING IDEAS INTO PRACTICE - March 21,

35 Problems and Future Challenges Technical problems in IFC implementation quality In many cases use of proprietary data formats is still the only functioning solution Product data must be available in compliant format Accurate as-built information as a by-product of ecommerce; not supported by current systems Identification (RFID) OK, but required data content is a complex issue Data of existing buildings Lack of specific education for the new tools and processes Education of architects and engineers in the universities is not based on the current modeling techniques, but mainly on traditional CAD MOVING IDEAS INTO PRACTICE - March 21,

36 Value in Optimization? Client s core business (200) FM services (5) (1) Building process Pressure to change Change adaptation Where are the real benefits of ICT? Design (1:5:200 - The Long Term Costs of Owning and Using Buildings Royal Academy of Engineering, UK) Construction MOVING IDEAS INTO PRACTICE - March 21,

37 Design as an Information Process If designers use the previous design solution, already modified information, instead of the actual requirements as the input for the changes, the end-result can easily shift from the goal. Client s requirements Initial solution Change 1 Increasing gap between the solution and the goal Goal Change 2 Change 3 Change 4 End result MOVING IDEAS INTO PRACTICE - March 21,

41 Conclusions of Finland s Situation In Finland interoperable BIMs are already a central part of the RECC practice and future strategy Not yet mainstream, but rapidly increasing All large construction companies use models For example, Skanska does not accept in their own projects designers who cannot deliver models Some technical problems exist, but main focus is now in the development of processes Reasons for success Critical mass; individual R&D projects have limited effect Long term vision and focused investment in development Willingness to collaborate combined with small market Education and interest in technology International collaboration and communication MOVING IDEAS INTO PRACTICE - March 21,
