Session 2.3
Scan2BIM on Linear Infrastructure Projects
Synopsis:
How is a BIM Model created out of Point Cloud for Facility Management, Digital Twin modelling, or Refurbishment projects? This presentation will focus on Scan2BIM processes with Grasshopper and Rhino.InsideRevit, using a case study of an 8 kilometers long tunnel.
Learning Objectives:
1. Scan2BIM Strategies
2. Grasshopper scripting
3. Rhino.InsideRevit
Body:
99.9% of the infrastructures that will be in operation in 2023 are already built today. However, the BIM Community is mainly focused on new development projects. But what happens when we need to refurbish or maintain existing structures? How do we create an as-built or current state BIM Model?
This presentation is a journey through the workflows and tools used by Amberg Engineering on Scan2BIM projects. We will talk about:
– Overall strategy: laser scanning, software selection and workflows, 3D modelling with scripts, metadata insertion, delivery formats.
– Point Cloud cleaning, classification and preparation.
– Import into Rhino / Grasshopper.
– Scripts development, 3D modelling.
– BIM Models creation using Rhino.Inside Revit.
