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
