[edit] Building Information Modelling and Scan-to-BIM

Building Information Modelling has transformed the architecture, engineering, and construction (AEC) industry by creating detailed digital representations of buildings. BIM goes beyond basic 3D modelling by integrating comprehensive data about a building's structure and systems. It enhances the design and construction process by offering a unified model that reflects both the geometry and the functional aspects of a building.

However, Scan to BIM Services use laser scanning to capture detailed spatial data of existing MEP (Mechanical, Electrical, and Plumbing) systems and convert it into accurate 3D models. This process creates a comprehensive Building Information Model (BIM), which integrates all MEP components for precise planning and coordination. The model helps visualise system placement within the building’s infrastructure, identify potential conflicts, and streamline the design and installation process.
