Building information model (BIM)
BIM advantages:
o Geometry
o Build ability
o Visualization of time schedule
o Quantity optimization and minimized waste
o Reporting
o Machine control
o Bar bending schedule from 3d models
o Data filtering
o Better understanding of construction
o Logistics
o Tolerances

Dias 47
BIM is used to optimize the project by building the model in 4D which incl. time schedule.
BIM will be used doing the planning- and execution phase.
