Thames Water – East Hyde Treatment Works

We employed a combination of traditional surveying methods and innovative techniques for this large-scale project, involving multiple surveyors.

Often, two surveyors ‘leapfrogged’ over each other to complete the laser scan locations, registering the areas into smaller, more useable Point Clouds ready to be transformed into a 3D AutoCAD model.

The hydraulic structure 3D Modelling required traditional surveying with Total Stations as well as laser scanning to measure unseen features below effluent levels like the internal weirs, pipe diameters, invert and coping levels.

This was a large project that involved a huge amount of data collection. To produce the Point Cloud of the pictured area took 1,475 laser scan positions. We used two Faro S150 scanners leapfrogging each other to collect and amalgamate over 63 million data points!

The image below shows a sample of the Raw Point Cloud data collected:
