Laser Scanning and 3D Modeling of Chemical Plant

We were contracted by a Plant in Kwazulu Natal to do 3D Laser Scanning of a specified area. We complied with all the safety standards and mobilised a scanning team to the Plant. The Laser Scanning was controlled using Precise Engineering Survey techniques and all Scan Data was registered together with a Standard Deviation of 2mm.

The contract specified that all Piping, Steelwork, Equipment and Utilities be modeled to a Standard Deviation of 5mm. We have streamlined workflows to extract and model Steelwork and Piping from the Point Cloud using Standard Libraries, so almost everything in the Model is to specification. Our team is very experienced and creative and we model custom objects like Vessels and Equipment as an accurate representation of the real world object.

We noticed that the concrete floor was not level (with height differences up to 200mm) to allow for drainage in the area where we were working. We modeled the Organic shape of the Concrete Slab with a Standard Deviation of 5mm in Height and this allowed for accurate clash detection and future design with tight tolerances.
