Project Highlights

• 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

• The new auditorium complex is an addition to the
  main building (1969) designed by renowned
  architect Alvar Aalto

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

Lessons Learned to Date

• We are amazed that this sharing of product
  model data in IFC standard is working in
  practice - the project architect

• 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

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

Industry Foundation Classes

• IFC defines a single object-oriented data model
  shared by all IFC-compliant applications.
• IFC is public and open for implementation and use
  by any member. It is evolving.
• In HUT-600 case, IFC 1.5.1 is strong in
  transferring building geometry, generating object
  identity, and specifying general material
  selection
