How much does Scan to BIM Cost? Guide to 2024

 

What is “Scan to BIM”?

Scan to BIM involves generating a digital model that mirrors the current state of a building, encompassing its physical and operational features within a BIM framework. Using specialized laser scanning technology, precise 3D scans are obtained and integrated into BIM software such as Autodesk’s Revit, Graphisoft’s ArchiCAD, Vectorworks, and others. This process allows for the creation of precise representations of existing structures or the incorporation of design elements into real-world contexts.

 

How Scan to BIM Works

The process of scan to BIM converts the visual and spatial aspects of a building or site into an easily understandable model packed with actionable information within a few hours. This technology is poised to replace several traditional construction tools, including basic tools like tape measure. Scan to BIM resembles 3D photogrammetry and, depending on how the 3D model is interacted with, has ties to augmented reality (AR).

The workflow of scan to BIM starts with a laser scanner, which can be attached to an aerial drone, mounted on a stationary tripod, carried around a site, or worn by an individual. This scanner captures spatial points that correspond to the site’s geometry—such as walls, doors, ground surfaces, openings, and more—tracking the position of each point along its x, y, and z axes.

The resulting point cloud contains vast amounts of data. Certain scanners can capture 2 million unique points per second and accumulate 600 million points within a five-minute scan. The scanner determines the position of these points by emitting a light beam and measuring the time it takes to bounce back. Lidar (Light Detection and Ranging) is the primary scanning method, although some scanners utilize SLAM (Simultaneous Localization and Mapping) algorithms, which can identify the scanner’s location while assembling the point-cloud map.
