  1. Helsinki University of Technology (HUT-600) Auditorium Project A case study in the application of: Industry Foundation Classes & 3D/4D Models Calvin Kam and Martin Fischer CIFE Summer Program 2001, Stanford University

  2. Project Highlights • The new auditorium complex is an addition to the main building (1969) designed by renowned architect Alvar Aalto • This research focuses on exchanging IFC product model data and on leveraging 3D models for visualization and 4D modeling • Efficient model and data sharing allows the project team to study more design alternatives, complete thorough analyses of life cycle costs and environmental impacts, produce virtual reality models for group decision making, and improve the construction sequence through 4D visualization

  3. Why HUT-600 for research/pilot? • The project stakeholders are also key participants in research and development sponsored by the Finnish government • The scale of the program is appropriate for experimental pilot work given a tight design and construction schedule • The complexity of the program offers challenges and requires in-depth alternative studies • The dynamics of the end user group (faculty, university facility managers, students, etc.) demand the best visualization tools to expedite client briefing and catalyze exchange of ideas

  4. National Technology Agency in Finland • Motivated by NIST’s study of 700 projects in the US that shows: • greater use of IT correlates with better project performance • both owners and contractors realise meaningful benefits • pronounced IT learning curve, but benefits outweigh risks • beneficial schedule compression • overall project cost savings ~ 1 % • construction cost savings ~ 4 % • Information Networking in the Construction Process International Alliance for Interoperability • 6-year research & development program under TEKES • total budget of USD $43 Million • of which USD $ 20 Million from TEKES • 80% for industrial R&D projects • 20% for public projects • Industry Foundation Class (IFC) • bringing information technology to building design, construction, and operation (A/E/C/FM) • industry-wide and continuous sharing of information is the starting point in bringing information technology to building design, construction and operation. • software interoperability: an environment in which computer programs can share and exchange data automatically regardless of the type of software or of where the data may be residing Center for Intergrated Facility Engineering • generate research goals • WDI/CIFE 4D tool in visualization, operation, space and facility management • document research progress • disseminate research findings Motivations for a Construction Pilot • TEKES • VERA • IAI—IFC • CIFE

  5. Goals of Construction Pilot • Support owner, users, and designers in early project decision making • Demonstrate benefits of product model approach from client briefing to design to construction to facility management • Prioritize agenda for further R&D related to the application of product models for information management

  6. Technologies for Construction Pilot • 3D and 4D visualizations of architectural design alternatives, lighting schemes, and construction schedule • Rapid analyses of several design alternatives for life-cycle costs, comfort, cost, energy, and environmental impact based on the same IFC-based product model • CAVE, project extranet

  13. Lessons Learned to Date • IFC 1.5.1 supports: • the transfer of building geometry, general material selection, and object names • Limitations with IFC 1.5.1: • It does not support specific material types • The file to represent HVAC design data is very large • Lighting data and its database are not in IFC standard, hence the resulting thermal loads from lighting fixtures cannot be directly updated • Schedule integration is not supported by COVE “We are amazed that this [sharing of product model data in IFC standard] is working in practice” - the project architect

  14. Benefits Learned to Date • Sharing IFC product model allows for: • earlier coordination between architects and MEP designers • more accurate cost estimation early project phase • better and earlier construction and procurement planning • faster generation of design alternatives • Various visualization tools (VR, CFD, 4D, etc.) allow for: • better and faster design coordination among different disciplines • more informative briefing and idea exchanges with the user groups

  15. Next Steps • Disseminate benefits and lessons learned from HUT project • Far-reaching decisions about project scope and requirements can be made early with accurate information • Full life-cycle analysis for many alternatives available early in design • Find 2nd pilot project
