4D model

Inspection

III) Tekla structures - BIM story in MTH Vietnam

17 April 2013 16

+) BIM process – the fact:

“Nothing says more than a building information model”

We are only on the way heading toward it

3D modeling solution is the only choice

+) Purpose:

Consistent model input and output

More automatically

Support other departments during constructions: design and engineering,

manufacturer, inspectors, etc.

Better communication

III) Tekla structures - BIM story in MTH Vietnam

+) Firm folder setting

Minimize inconsistent input

Easy for filtering

No numbering error

Easy control project

+) Custom component

More automatically

Speed up QA

+) Tekla Open API

Applying available shared extensions on Tekla extranet

Built some small macros and applications
