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

Sidefod

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.
