Research goalsWork flow
How does 4D CAD fit in the existing working procedures, or is another procedure necessary?
Data management
Is the data needed for 4D CAD available in the right format from the existing CAD systems and planning systems?
User requirements
Can construction managers handle the application and does it support their work?
Organisational requirements
How is 4D CAD related to the other business processes (finances, resource management, document management, risc management, etc.)?

work method
• Like current situation, 4D software is used as an extension
• Integrated work method• Fast generation of alternative
models
• Integrated work method, using SAP [and SAP WBS] - NO 3D/4D!
• Paper based• PowerProject software

ConclusionsNaming convention
• Databases
• Facilitation of 4D model creation
• Consistency!
ERP software• Most effective basis for cooperative and integrated work method
Organisation structure of projects• Greatly influences opportunities for effectuation of intended work
methods
• Design & Build seems most valuable
