BIM
Architects' willingness to share information with project partners (contractors, engineers, subcontractors, specialists, manufacturers, etc.)
We never share
We are very careful when sharing information
We only share information when requested to do so
We share the information with a proactive vision
Sharing is multiplying so that transparency benefits theproject

Eindhoven City Hall
What are the reasons that led you to consider the use of BIM/DfD in this project?
"We used BIM because we wanted to work constructively with the different project partners. Thanks to the high level of cooperation, many
errors were discovered during the design phase.“
(Terry Pater)

At what stage of the project did BIM help you in relation to the traditional working method?
"BIM allows us to facilitate the production of documents and get a
good overview of connections.“ (Terry Pater)
