What is the Scan to BIM Process?

Building Information Modeling in construction is gaining popularity in recent years. Architectural, Engineering, and Construction professionals are seeking scan to BIM processes for enhancing their businesses. As per industry research, it is found that the global scanning market would rise at a Compound Annual Growth Rate (CAGR) of 8.4% from 2019 to 2025. Several companies providing point cloud to BIM services in California are optimizing building projects with integrated analysis, design as well as simulation tools. But what’s the technique all about?

We would explore the  3d scan to BIM modeling process in detail. However, before that, let’s take a look at a few details.

What is Scan to BIM?

  • The technique involves BIM model creation from a 3D scan.
  • During laser scanning, 3D scans are captured and imported into BIM software, such as Vectorworks, or Revit.

Benefits of Scan to BIM Services for Construction:

  • Cost-effective construction
  • Improved renovation
  • Faster decision-making
  • Cost control

Challenges involved in the Conventional Process:

The conventional process involves manual measurement, design as well as completion of construction through as-built capture, sketches, and overlay. This resulted in:

  • Inaccurate measurement
  • Difficulty in tracing measurements over hard copies
  • Illegible handwriting, leading to safety hazards, multiple on-site visits & delays

What is the Scan to BIM Process?

The technique involves scanning, processing, and modeling along with as-built. The steps include:

  1. Identifying Level of Detail (LOD):
  • Determining the level of detail for the 3d BIM modeling.
  • Accuracy and greater reliability of the as-built model.
  • Information identified at this stage encompasses building elements, level of detail, and non-geometric attributes.
  • A detailed model calls for enhanced cost and so the data density is rightly balanced with the price.
  1. Making the Plan:
  • Fixing parameters, as it becomes difficult to find out existing construction documentation like:
  • Space and angular resolution
  • Accuracy
  • Coverage

  1. Executing 3D Laser Scanning:
  • Laser scanners capture the interior as well as the exterior structure, including architectural, structural, MEP as well as fire protection installations.
  • Using Revit software, the scanned data is turned into a 3D model.
  1. Using the 3D model in BIM:
  • At this stage, the scan gets converted into a BIM model with as-built capture of an existing building structure.

How do BIM engineers work with point cloud to BIM modeling services?

  • Laser scan point cloud modeling companies develop Revit (.rvt) and CAD (.dwg) files from various scans as well as point cloud data capture machines like Leica, Faro, Trimble, Reigl, etc.
  • Engineers convert data format ( .fls, .pcg, .obj, .ptg, etc.) into BIM Revit model.
  • An information-rich BIM 3D Model is created for clash-free integration amongst architectural, structural, and MEP services.

2 facets of the scan to BIM process:

  • Interpreting Point Cloud Data: Point cloud scan of the construction project gets imported into 3D laser scanning BIM software, like Autodesk Recap.
  • 3D Modeling: 3D model facilitates as-built capture, catering renovation, and remodeling of a structure.

Final Thought:

Point cloud Revit BIM process is used by commercial companies, architectural design-build firms, MEP engineering companies, contractors, and subcontractors.
