Workflow Scan to BIM: Dari Pemindaian hingga Model Digital

One Stop BIM Solution

In the construction and architecture industries, Scan to BIM technology is increasingly being used for building digitization. This method enables the conversion of scanned data into accurate Building Information Modeling (BIM) models. Scan to BIM is particularly useful for renovation, reconstruction, and asset management of buildings.

This article will discuss the steps in the Scan to BIM workflow, from scanning to creating a ready-to-use BIM model.

What Is 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.

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

   The processed point cloud is ready to be modeled with various BIM software as needed.

From planning to implementation, each step plays an important role in producing a quality BIM model. With the development of technology, this method is increasingly becoming a standard in the construction, architecture, and building management industries.

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.
