what is 4D simulation
process of combine 3D model with the project schedule
Utilizing 4D simulation enhance the work processes during the proposal
automated quantities with 5D technologies
Quantity surveyor
quantity
cost estimation
report / BQ
site valuation
comparison
Problem facing
no time for preparing bill of quantity (BOQ)
hard to compile all resources in one place
take time to finish report
loss track previous information
need to keep update latest price from supplier
Manual to Automation
Transformation
prepare BOQ
Keep BOQ in one place
Update price

take off and update in BOQ
3D BIM quantity take off
Taking off
To measure building
cost estimate
Resource database

Quatation
to price the BQ item
what is 5D quantification
BIM can be used to assist in the generation and collection of accurate quantity take-offs
economic variable will estimate the cost of the project, in order to control and estimate cost
using the information model to
generate quantity take-off
calculation
measurements directly from the model
Building Information Modeling (BIM)
BIM stage
Stage 0
unstructured information
Stage 1
Structured information
Stage 2
Federated information models
Stage 3
Database based information model
what is BIM
BIM is aproject that should build twice
once fully modelled digitally
once again for real project site
