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

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
