Scan to BIM

Scan to BIM

Scan to BIM is the process of scanning a physical object such as a building or structure into an accurate digital model. Scanning uses accurate technology, such as a laser scanner. The laser scanner will scan the object by emitting laser pulses to the object to obtain a set of point clouds that form a 3-dimensional model. The point cloud data is processed such as merging and removing unnecessary noise. The processed point cloud data is used as the basis for creating a BIM model according to the desired LOD.

GeoBIM Indonesia successfully applied Scan to BIM on various objects, such as school buildings,mosques, heritage, and toll road infrastructure. With experience in point cloud data processing and BIM modeling, GeoBIM Indonesia has helped various clients improve their project efficiency and asset management. GeoBIM Indonesia provide 3D Modelling from Scan-to-BIM point cloud with various level of detail (LOD) from 200 until 500. Then the 3D model could be developed to BIM 7D (Asset Information Model) with input the information, parameter, and attribute those are needed.

Benefits of Scan to BIM:

1. Informative asset management
Using the BIM model generated from the scan, building owners or managers can have a highly accurate digital representation of their assets. This model includes detailed information such as dimensions, materials, and structural elements of the building.
Benefits:

• Eases building management and maintenance with more complete and accurate data.
• Enables regular monitoring of building conditions without having to conduct on-site inspections.
• Provides real-time data that can be accessed at any time to support decision-making.

2. As a reference for plaining renovation and recontruction designs
With the Scan to BIM model, architects and engineers can use existing data as a basis for planning building renovation or reconstruction. The model provides a high-precision view of the existing building conditions.
Benefits:

• Reduces design errors as the model is based on actual data.
• Speeds up the design process as there is no need to recreate the building model from scratch.
• Optimizes cost and time as planning is based on accurate data.

3. As a reference for replicating designs
If a building design needs to be replicated for another project, the Scan to BIM model allows this process to be done more easily and accurately. The scanned model can become a template for a new project with modifications as needed.
Benefits:

• Saves time in design as there is no need to redraw from scratch.
• Ensures design quality and consistency between projects.
• Facilitates the development of large-scale projects.

Scope of Work:

• Point Cloud Data Acquisition : scanning of objects using a laser scanner and recording data in the form of point clouds from various angles.
• Point Cloud Data Registration : combining point clouds from multiple scans to form a single data set.
• Clean the noise point cloud and ecport to formats supported by 3D Modeling software (.rsc, .rcp, .lgs)
• Perform 3D modeling from point cloud data : converts point clouds into 3D models with customized level of detail (LOD 200-500)
• Input object parameters and attributes: add technical information to the model, such as materials, dimensions, and building specifications
• Developing the model into BIM 7D (Asset Information Model): Integration of operational and maintenance information to support long-term asset management

Final Product 3D Modeling Using Scan to BIM Method

1. Registered Point Cloud : the result of merging point clouds from various separate data captures.
2. 3D Model : a digital representation of a physical object in the real world.
3. Mesh and Contour: Detailed surface representation of the scan results that are useful for analyzing the shape and topography of the building.
4. Video Walkthrough: An interactive visual simulation that allows users to virtually explore a 3D model, particularly useful in project presentations and design evaluations.

What Is the Flow of Scan to BIM?

1. Planning and Preparation
Planning and preparation takes place before the entire process is carried out. This includes identifying the project requirements, selecting the appropriate scanning tool, and planning the scanning path. Planning should consider the purpose of the Scan to BIM, the size of the scanned area, and the level of fidelity.

2. Field Data Acquisition
Data acquisition is carried out after all preparations and planning have been completed. Data acquisition uses a laser scanner according to the scanning path created. The laser scanner will scan the object to be modeled by emitting laser pulses to the object. The result of the scan is point cloud data.

3. Point Cloud Processing
Before being modeled, the point cloud will go through several processing steps. The first is point cloud registration, merging point clouds from various scans into one data. After merging, the next step is filtering and noise reduction to remove unnecessary points. Last, point cloud segmentation to separate different objects, such as walls, columns, and roofs.

4. BIM Modeling
Use BIM software to convert point cloud into digital model, define LOD (200-500) according to project needs, and add additional information to support asset management (BIM 7D).

With a wide range of benefits to offer, from more informative asset management, accurate reference for renovation and reconstruction, to support in design replication, Scan to BIM has become an innovative solution in the construction, architecture, and building management industries. The resulting final products, such as registered point cloud, 3D model, mesh & contour, and video walkthrough, enable asset owners and industry professionals to work more efficiently, accurately, and sustainably.
