BIM & Scan Ltd. develops products and services that are focused on quality open BIM solutions to real engineering and construction management problems.
We use Open BIM standards to deliver software independent solutions that work with any software that supports those same open BIM standard solutions.
BIM & Scan® AutoCorr™ is a tool developed for automatic model validation with scan data. BIM & Scan® AutoCorr™ automatically highlights any variations between a point cloud and model using a specified tolerance. The output is a colour-coded point cloud which highlights all variations within the specified tolerance.
A single field clash can run to many thousands in cost, not to mention delay. Field clashes occur even where there is a “clash free” model. Field clashes can occur when construction does not match the model, often only becoming apparent in the next or several tasks after the offending error. Field clashes can be avoided by construction monitoring and validation, provided you have an efficient and effective way of comparing as-built with the design model. BIM & Scan® AutoCorr™ provides a fast efficient and objective comparison, providing in minutes the necessary construction validation against the design model.
We have found that having a phased plan of construction validation using BIM & Scan® AutoCorr™ delivers cost effective clash and delay risk avoidance. For example, on completion of plinths validate as-built plinth locations against the design model prior to committing final steel or pipework manufacture; validate steelwork and facia ties prior to delivery of pre-fabricated facia.
Inaccurate as-built models can cause numerous field clash errors where they are relied upon for retrofit work. These inaccuracies only become obvious when the design no longer fits or clashes with items missed in the modelling process. BIM & Scan® AutoCorr™ provides certainty for the design team and its client that all items have been captured.
Overlaying point cloud scans on the model and then visually inspecting is a very expensive and subjective alternative that is often tried but will cost many multiple hours more effort and will still fail to find all the impacting issues. This takes hours or days of skilled workers time rather than the minutes to complete a BIM & Scan® AutoCorr™ analysis which gives accountability for every design element.

The output is a colour-coded point cloud which highlights all variations within the specified tolerance, along with an automatically created BCF viewpoint of each design element and a listing of each design element and whether it was found or not.
