Maidenhead, UK, 01 May 2019 – Global construction services company ISG is using the latest 3D modelling technology to boost its BIM capabilities. By introducing Pointfuse laser scanning software, ISG has speeded workflows with rapid scan-to-BIM modelling whilst maintaining high levels of accuracy. Traditionally this laser data processing could take up to three days to 3D model a single floor, however, using Pointfuse ISG has reduced this to a matter of hours. The use of Pointfuse has also increased the range of the point cloud outputs with applications including clash detection and visualization.
“Scan-to-BIM modelling was previously seen as undesirable by the construction industry due to the time taken to complete and the risk associated in doing so,” commented Ben Callan, BIM Coordinator in ISG’s UK Fit Out business. “However, using Pointfuse we have further improved our ability to push out point cloud data; accelerating analysis and modelling output and defining this output with improved tolerances and levels of detail. This ultimately enhances our BIM offering as a business.”
ISG had already recognized the benefits of capturing accurate site or as-built conditions using a Faro M70 laser scanner to capture and analyze point cloud data to support BIM delivery and 2D design. In order to understand the potential of Pointfuse, ISG benchmarked the software against traditional means of modelling to determine which method was best for the business.
Using Pointfuse ISG accelerated its 3D model output reducing the time taken to produce a model from between 2-3 days to just four hours per floor. Offering selectable geometry Pointfuse has also removed ISG’s reliance on the complete point cloud for modelling, allowing users to work with only the data they require for a specific application, realizing additional time savings and efficiency gains.
ISG can also take sections from the generated mesh model which can be instantly output for comparison with as-built drawings and scans and output file sizes have been reduced from gigabytes to megabytes making the data more widely accepted and usable.
“Using Pointfuse we can create intelligent 3D mesh models in a fraction of the time,” continued Callan. “This accelerated modelling and reduced risk of error contributes to a direct reduction in costs when compared against traditional methods of modelling and point cloud data analysis. The easy to use, easy to consume outputs are also paving the way for new applications of the data including existing versus design clash avoidance and checks of temporary works against required construction activities.”
Pointfuse is a powerful modeling engine that delivers an automatic, precise and flexible way of converting the vast point cloud datasets generated by laser scanners or photogrammetry into segmented mesh models. Pointfuse uses advanced statistical techniques to create 3D models where individual surfaces can be selected and classified as new layers in the Pointfuse environment and exported to IFC and FBX for manipulation in any industry-standard CAD system. Offering ‘selectable surfaces’, Pointfuse provides a unique approach. Surfaces within the 3D mesh models produced by Pointfuse can now be identified, grouped and classified. These advancements within Pointfuse bring a catalyst to the workflow of design and engineering projects, offering efficiencies that have not been possible when working with point clouds or traditional mesh models. Pointfuse also significantly reduces the file size of 3D models created from point clouds. In simple terms, the data density within each surface is reduced whilst still maintaining the fidelity of the model. This results in a significant reduction in model size making ongoing use of the model easier, faster and more efficient. http://pointfuse.com
