Point Cloud Conversion to 3D Modeling – Point Cloud (SCAN) to BIM


The AEC industry has traditionally depended on 2D illustrations to communicate design and construction information. However, with the advent of Point Cloud technology and converting these point clouds to 3D models such as BIM, the construction industry has taken a giant leap in the age of digitization. Point Cloud to BIM or SCAN to BIM is proving to be an efficient and agile solution for laser scanning an area or landscape and using 3D models to represent a precise digital illustration.

Point Cloud to BIM or SCAN to BIM can be applied to various processes of a construction project such as: construction area or site affirmation, design planning, design verification, design evaluation, MEP Coordination, As-built drawings, Remodeling/Renovation, quantity takeoffs, budget estimate, etc.

Point Cloud conversion to BIM or SCAN to BIM

Scan-to-BIM (or point cloud to BIM) is the process of capturing and illustrating high density point clouds of a landscape, structure or site to create a 3D BIM model. Once the point cloud data is generated it is a raw representation of data or focus points from laser scanners like LiDAR or photogrammetry. The point cloud is needed to be converted to mesh to create a data-rich and precise 3D model. The Point Cloud meshes are created using a 3D solid modeling program in detailed BIM models depicting how the components blend in the building system.

A 4-step guide to convert Point cloud to BIM or SCAN to BIM


Collect all the information about the project, define the Scope of Work, Level of Detail, BIM execution plan and the deadline of the project. This stage focuses on the client expectations, evaluation of the scanning device aligned with capability or capacity of the scanners and finally the onsite condition before capturing the data points of the site.


As soon as the information about the as-built conditions of the facility or site is validated and collected, this information needs to be scanned. The scanned data needs to be aligned using different ways like best fit, ortho, geo-referencing, etc. 


This stage determines the digital illustration of the point cloud to a 3D BIM model. Following are the steps described below:

I. Validation – Clear communication about the LOD (Level of Detail), LOA (Level of accuracy), and Scope of work required for the project. A clear and well-defined Tolerance level of Deviation enables a successful implementation of a BIM Execution Plan (BEP). The coordinates and data points of the point cloud are to be validated with the help of tools like: Faro, Clearedge3D, Leicia Geosystems etc.

II. Insertion – Once the Point cloud is validated the files are inserted into REVIT and locked down with a PIN tool.

III. Setup – Work sets should be made by the need of the task to start the process of file setup in REVIT. Diverse work sets are advised for each Point Cloud in order to set the VVGG setting and turn on/off as required, thereby reducing the file’s open time. Ensure to lock it to set up the levels from a Section View. The following can be the levels:

  • Level 0: Level 0 should be set through the Origin Point of the Point Cloud Scan. It can/cannot be with the Project levels was it will be the reference point.
  • Building Levels: It will depend on the project. The modeler must set the level line through a representative part of the floor that the Point Cloud is showing. For setting up several levels in the model at a time, we can place the Section through a stair core.
  • Set Plan View: It will be set according to the created levels by the modeler.
  • Girds: Girds should be set up by using the main floor of the building and set an objective of the grid system throughout the model with regular distance wherever possible

IV. Modeling – All the components must be represented and modeled as individual accurate Revit Elements, a collection of a single column must be applied, instead of a generic model with # of extrusions, all the components must be hosted to the corresponding levels. The walls of the model must be most suitable fit to the Point Cloud by slicing thin view angels in plan and section views. When modeling a boundary wall in a plan view, always select the option of Interior/Exterior Finish as wall restrain.

V. Collaboration – Effective Communication among stakeholders is the key when it comes to 3D modeling. All the stakeholders should be using the same storage path of the Point cloud, compatible program, version, and updates. Have a control model for the setup of levels, grids, and shared coordinates, this will ensure that none of the participates will be able to modify, move, or delete the information.


Follow a thorough QC process to ensure the quality of the model. It is recommended to do a meticulous comparison of a demarcated area by using Plan, Section, or 3D view. Clash Detectionfor MEP Coordination. It is very important to clean the file to delete all the reference points and detailed lines from the model.

When you WANT to ensure ACCURACY

Application of Scan to BIM Services across different services 

1. Point Cloud to BIM in Architecture

Detailed and Precise Architectural 3d models can be created for interior, exterior and site deigns from the point cloud scan. Businesses into Renovations and Remodeling can benefit in terms of cost, time and efforts for their survey needs. Laser Scanners enable capturing rough and larger terrains with ease, precision and safety. A current plan can be created to recognize and execute the new proposed design post-renovation. Accurate As-built drawings can be achieved and transformed into existing data models with dimensions.

2. Point Cloud to BIM in Structural

A deep and detailed scan of a structure to exhibit columns, beams, connections, foundation slabs etc. can be achieved with ease and precision. Any change in the present structural Model can be easily determined to enable prepare for the new ones. This method lessens a lot of time and is cost-effective compared to the manual survey.

3. Point Cloud to BIM in MEP

Scan to BIM Services play an integral role in the MEP coordination. From understanding existing designs to implementing new ones, clash detection and maintenance and reconstruction, such As built models come handy throughout the project life-cycle.

Point Cloud (SCAN) to BIM benefits

  • Save time in surveying and scanning – Precise and Agile
  • Cost-Effective – Lower your construction cost
  • Progressive – Enhanced communication and collaboration
  • Better decision making – Ease of Alterations
  • Enhanced Sustainability of Project – Detailed building analysis and cost estimation
  • Better Design Assessment Renovation or Refurbishment

More than 45% of the AEC industry is moving toward the precise and agile technology of Point Cloud to BIM or SCAN to BIM modeling. Point cloud models can accurately illustrate relatively complex landscapes and objects with a large number of data or focus points to generate precise 3D models.
