As-Built Documentation from Laser Scanning
Generate accurate as-built drawings and models directly from laser scans. Ideal for renovations, compliance, and asset records, our services provide reliable documentation of existing site conditions.
As-Built documentation from laser scanning
Accurate as-built documentation is essential for organisations planning renovations, infrastructure upgrades or engineering projects. Many buildings and facilities have incomplete or outdated drawings, which can create significant challenges when planning new work. Laser scanning provides a highly accurate way to capture the geometry of buildings and infrastructure and convert this information into reliable as-built documentation.
3D Walkabout provides professional as-built documentation services using laser scanning, helping engineers, architects and property owners obtain accurate digital records of existing environments. Using high-precision LiDAR scanning technology, millions of spatial measurements can be captured in a short period of time. These measurements create a detailed point cloud dataset representing the geometry of the building or infrastructure asset. The point cloud data can then be converted into accurate CAD drawings or BIM models that represent the current condition of the facility.
By using laser scanning to create as-built documentation, organisations can significantly reduce the risk of errors when planning renovations, facility upgrades or infrastructure projects. Accurate as-built drawings allow design teams to work from reliable information, ensuring that design decisions are based on the true geometry of the environment.
What is As-Built documentation
As-built documentation refers to drawings or digital models that accurately represent the current condition of a building or infrastructure asset. Unlike design drawings, which show the intended design of a project, as-built documentation reflects the actual geometry of the completed structure. Over time, buildings and infrastructure assets may undergo modifications, upgrades or repairs that are not reflected in the original drawings. As a result, existing documentation may no longer represent the true layout of the facility.
Laser scanning allows organisations to capture the current condition of an environment quickly and accurately. During scanning, LiDAR scanners capture millions of spatial measurements that form a detailed point cloud dataset. This dataset represents the exact geometry of the environment.
From this dataset, specialists can create:
- floor plans
- building elevations
- cross sections
- structural drawings
- BIM models
These drawings and models provide an accurate representation of the facility and can be used as the foundation for engineering and design work.
