AS-BUILT BIM MODELS

Buildings and structures often deviate from their original designs due to modifications made during and after construction. As a result, traditional design models and plans may no longer represent the building’s actual state, potentially leading to errors and increased costs during renovations, maintenance, or other operations. To address this issue, 3D laser scanning can be used to create as-built Building Information Modeling (BIM) models that reflect the structure’s current condition, including any changes or deviations from the original design.

Point cloud data acquired through 3D laser scanning enables us to either update existing BIM models or generate new ones, ensuring they accurately represent how the structure truly exists rather than how it was initially planned. BIM models themselves are 3D CAD representations commonly used in civil engineering and architecture to incorporate not only structural elements but also mechanical, electrical, and plumbing (MEP) systems. From a BIM model, 2D documentation—such as floor plans, ceiling plans, and section and elevation views—can be generated automatically.

Because BIM formats are often incompatible across different software platforms, exchanging data between them can introduce complications. To prevent this, we create BIM files directly in the client’s preferred software, preserving data integrity and functionality. Additionally, we tailor the Level of Development (LOD) of a BIM model to match a project’s requirements to balance cost, timeline, and necessary detail, ensuring the model meets all needs without unnecessary overhead.
