Scan-to-BimConverting point cloud to intelligent models
Scan-to-BIM (sometimes scan-to-model) is a pretty easy workflow to understand.
The data is acquired by a laser scanner (hence scan). The data is registered - that is the scans are aligned. Being surveyors, we then typically align the data to some other coordinate system (eg site grids) or put the point cloud data on to horizontal or vertical datums - eg Australian Height Datum - AHD.
The data is then prepared for the software downstream. Internally we publish to a Leica Geosystems format - either Jetstream or LGS - and we highly recommend regular users of point cloud data check out Cloudworx. For Revit and Autocad - a typical format used is Recap - so we publish the data suitable for use in Recap (and therefore Revit/Autocad). Other software like ArchiCAD can take E57. Either way, we can prepare your data to suit.
Once the data is organised and ready, the process of modelling or extract can begin.
Our expert modelling team will "trace" over the site and structures to create not only typical CAD - but also the more advanced Revit and IFC models (hence BIM/model), some examples of which you can explore below in our Recent Scan-to-BIM projects.
We can work to any level-of-detail required. One of the best things about point cloud data is, it is always available. We can start with floors and walls, then add ceilings, windows, doors, then drill down to basins or toilets - basically we can add more and more detail as the consultant team wants it - even varying the level of detail across a site. Every site is different - some sites are being demolished, some sites are being retrofitted - so we will work on the specifications for your projects with you and your consultant team.
