How Scan to BIM Works: Step-by-Step Process

Scan to BIM transforms physical spaces into detailed digital models, enabling accurate project planning and updates.

3D Laser Scanning and Point Cloud Data

The process begins by capturing the existing conditions of a building using 3D laser scanning technology. These scanners map a site by recording millions of points in space, each marked by its position along the x, y, and z axes. The result is a highly detailed 3D digital representation known as a point cloud.

Some advanced scanners can collect up to 2 million points per second, producing as many as 600 million points in just five minutes. This data is incredibly precise, often accurate to within a millimeter or less. Most devices rely on Lidar (Light Detection and Ranging) technology, while others use SLAM (Simultaneous Localization and Mapping) algorithms. Before scanning, it’s essential to define the project’s goals and adjust the scanner’s settings, such as point density. Multiple scans from different angles are then combined to create a complete 3D model of the space. With the point cloud captured, the next step is turning it into a structured BIM model.

Converting Point Cloud Data to BIM Models

Point cloud data, while detailed, isn’t immediately usable and needs to be converted into a BIM model. This can be done manually or through automated tools like Autodesk ReCap Pro.

During this stage, the raw data is translated into recognizable building elements. For US-based projects, measurements are converted to inches and feet to align with standard practices. Accuracy is critical here, so teams cross-check measurements against known dimensions and review scans from multiple positions. This ensures the BIM model is a dependable resource for design decisions and construction planning. Once the model faithfully represents the structure, it’s ready to be integrated into the project workflow.

Adding to Project Documentation

The final step involves embedding the BIM model into project documentation. By incorporating metadata into the digital point cloud, teams gain access to reliable, detailed information for planning, revisions, and maintaining project records.

Tools and Software for Scan to BIM

Transforming real-world data into precise digital models depends on the right mix of hardware and software. For architects and builders, understanding these tools is key to streamlining workflows and ensuring project success.

Hardware: Laser Scanners

Terrestrial laser scanners are the go-to choice for construction and architectural projects. They provide high-quality, accurate data by using lasers, sensors, and GPS to capture precise coordinates. These scanners emit low-energy infrared laser light and can capture 360-degree images of their surroundings.

When speed is more critical than pinpoint accuracy, mobile mapping systems are a practical alternative. They’re ideal for covering large areas quickly, such as campuses or expansive facilities. For sites that are hard to access or involve elevated structures, aerial scanning becomes invaluable. This method captures details of rooftops, facades, and other challenging areas that terrestrial scanners might miss.

For projects on a tighter budget, photogrammetry offers a cost-effective option. By using overlapping photographs to gather dimensional data, photogrammetry provides a basic level of reality capture. While it doesn’t match the precision of laser scanning, it’s a practical choice when budget constraints take priority.

Software: BIM Platforms

Turning point cloud data into functional BIM models requires specialized software tailored for the task. Autodesk Revit is a leading option, widely used for its extensive capabilities and compatibility with point cloud data. It’s particularly suited for US-based projects, as it supports imperial measurements seamlessly.

For speeding up workflows, EdgeWise is a standout tool. It integrates with platforms like Revit, Plant 3D, and AVEVA E3D Design, cutting scan-to-BIM processing times significantly. In fact, EdgeWise has been shown to accelerate workflows by up to 73%.
