BIM Software for Buildings & Infrastructure
OpenBuildings is a comprehensive BIM solution supporting Design, Construction, and Operations for buildings. It offers robust file interoperability, enabling architects, surveyors, engineers, and contractors to manage large-scale projects with BIM.

Software Features
Key Workflows

Clash Detection
A typical building consists of thousands of elements that may conflict with one another. With BIM, you can detect and resolve these clashes before construction begins, saving time and money. OpenBuildings allows you to model MEP & Structural elements in 3D, and run clash detection to identify and resolve potential issues.

Generate Shop Drawings
While BIM is the tool of choice for project delivery, site workers still rely on 2D plans that can capture details that are hard to capture in BIM. With its integrated CAD tools, OpenBuildings allows you to generate shop drawings from your 3D models, ensuring that your site workers have the information they need to build accurately.

Visualization & Planning
During the design phase, engineers can display survey information captured from LIDAR or drones alongside their BIM models with iTwin Capture. For tender presentations, LumenRT can be used to create immersive visualizations that help clients understand the design intent.
