This case study concerns the establishment of Denmark's first PPP hospital, involving several AEC firms, navigating a complex project, by actively using BIM models for collaboration and user involvement in all phases of the building process. The lecture intends to inform of 'quick wins', successes and how to avoid pitfalls. Key Learning Outcomes: 1. Knowledge concerning our experiences in creating an ICT framework that supports/contributes to a better cross disciplinary model collaboration. 2. Inspiration on how to actively use the models on-site, both for white- and blue collar workers. 3. Knowledge about which information the models should contain in order to be useful both in the design and construction phase

1.3. The first PPP Hospital Project
Public Private Partnership.
Private investor responsible for running the
building.
BIM workflow supports a PPP project.

11. 11
1.4. ICT specification
All involved have BIM / VDC
experience and very high ambitions
for the project, even though the ICT
agreement indicated a medium level.
Model:
• LOD / LOI 350
• Drawings
• Tender with quantities
• Simulations / Analyses
• Operation and maintenance

2.0. First BIM Challenges

15. 15
2.0. - First BIM Challenges
Causes of Challenges
• Sold on low BIM expectations
• Unambitious ICT agreement
• One of the first BIM projects,
using the 3D models active.
• Late involvement of BIM experts.
• Construction is carried out while
the project is on going.
• High demands on cooperation
Types of Challenges
• Project is placed far away from
Origin in the architecture model.
• Coordinates is not acquired correctly
in the architecture model.
• Things can not be corrected in the
model, places this has bin built.
– Things have an influence on
others.
• Autodesk products was not good
enough.

2.1 Solution
Meeting between all
Participating
• All BIM heads from the
companies sad down.
– NTI CAD center as adviser.
Solution on this project
• How to manuals was made
– How to startup new models
– How to link models
– How to Export IFC
– How to combine IFC

3.3. Reflection
• Who is responsible for the
quantities, and what possibilities
are there with todays legislation
and tools?
• How is the industry coping with
BIM models vs. tolerances?

5.0. Knowledge sharing

44. 44
5.1. Knowledge sharing
through objects
Need to know vs Nice to know
• LOD
• Which information are needed:
– Drawings
– Schedules
– Tender specifications
Predefined schedules
• Follows the development
• Same information and setup
every time

45. 45
5.2. Interfaces between trades
Anxiety
• Economy vs Responsibility
• Example:
– Automatic door locking
systems
– Plumbing fixtures
– Loose and fixed furniture

46. 46
5.3. Sitemodel
AutoCAD vs. Revit
• MOE designed wells and pipes in 3D
• Landscape architect should indicate elevations on the well covers.
This was missing!
• MOE did this in exchange for additional payment.

47. 47
5.4. Reflection
Defining responsibility
• Features in applications
• How to manuals
• Get together meetings
– In front of the computer
– Across offices
• Remove the fear of
interfaces

48. 48
5.4. – Findings
• Collaboration ALWAYS pays off especially when this mindset is agreed
upon from day one.
• Structure, structure, structure……. and more structure
• The technology development is moving so fast that for instance
Bluebeam/VR glasses/BIMcollab would have made a difference, and made
our workflow easier. This holds great promise for the future!
• Important to retain keypersons on the project, and keep the knowledge
throughtout the project.

49. 49
Future tendencies?
What can we expect?
• The BIM model will be used even more
• More use of intelligent digital solutions in all areas of the ACE
industry.
• Disruption, other industries will find way to the ACE industry
• A fourth industrial revolution is around the corner – much will
change between now and 2025.
• Firms with the ability to collaborate and accept change will survive
