BIM

▪ Scan data can be used in the whole of the BIM process

▪ Planning

▪ Design

▪ Construction

▪ As-built conditions

▪ Capture data where traditional survey methods are difficult

▪ Capture all data in a short space of time

MANAGE

BUILD

DESIGN

PLAN

▪ Previously drawing based

▪ Risk of errors

▪ Duplication

▪ Simplification of 3D Data

-> Shift to model based

-> Minimized errors

-> Single model - lots of views

-> Visualisation and simulation

-> Easy data access by all
