Scan to BIM for Mechanical and Electrical provision is commonly required particularly where changes have happened over time and an updated AM record is required. ESL can provide high resolution scanning and production of BIM models to meet this demand.


Scanning is also useful in preparing as built documentation where a structure is freeform and high tolerance.

Scan to BIM software easily shows where problems may lie.


3D Modelling and Points Cloud Mesh’s allow the preparation of simple fly-thru videos which can in turn be used as a training tool prior to work

As the models and mesh’s have already been prepared as part of the engineering design it’s a small step to combine the information.


The model shown left was produced from Aerial Photogrammetry and combined with interior Laser Scanning to provide a complete point cloud record. ESL then produced a structural BIM Model from this point cloud. Drawings and Sections were then provided to aid in the museum upgrade (see below).


Surveyors involved in building construction need to be familiar with BIM and have the ability to extract geometric data for use in site setting out. The presentation of as-built data in the BIM format is also fundamental to the sharing of data both upstream and downstream in the BIM process.

This hotel in Macau Hotel has a complex exoskeleton.  ESL used BIM, Scanning and traditional techniques to aid the construction.
