BIM – Building Information Modelling

3D Visualisation Model

Building Information Modelling (BIM) is a process that allows building professionals of various disciplines to generate and manage the digital representation of the building data throughout its life-cycle. More often than not it involves working on a 3D digital model.

The adoption of laser scanning technology for survey measurement has brought about the ability to capture huge amounts of field data more quickly and accurately. One of the great advantages of point clouds is that they are three-dimensional allowing the data to be visualised interactively using 3D fly-throughs or panoramic views.

CGD Ltd… We are already on the BIM ladder

CGD Ltd… We are stepping up the BIM ladder

The role of the land surveyor has been evolving over many years as new technology changes the way we work. In the last 15 – 20 years we have seen numerous improvements to our equipment including  ‘one man’ robotic total stations and GPS. More recently we have witnessed a sea change as the introduction of laser scanning  technology has revolutionised the way in which surveyors take measurements. Long gone are the tape measures, dumpy levels, theodolites and staves (although there is still a use for some of these items) . At the same time the introduction of BIM in the AEC industry has changed the way we approach construction projects. Stakeholders are now reassessing the opportunities technology provides and streamlining their processes. Continue reading CGD Ltd… We are already on the BIM ladder

University of Worcester: Survey models for maintenance

The University of Worcester is using Building Information Models to document its existing properties for future maintenance and management


As a part of the University of Worcester Estate Development Programme, they are converting their building documentation from CAD to BIM and also want to explore the opportunities of BIM to help them manage their facilities and properties better. CGD Ltd was commissioned to carry out the laser scan survey and produce 3D Revit models of the Riverside Building and the Garage Building. CGD Ltd is proud to be part of this programme; our experienced BIM team produced the 3D models which will prove useful for maintenance and as a basis for alterations design.

  7. Microstation (DGN)

From 2nd to 3rd dimension

Moving from 2nd to 3rd dimension, is it worth it?

Studies published in the Smart Market reports in 2010 showed that in the UK, at least 35% of construction professionals were already using 3D technology. This means that nearly 65% were still using 2D CAD systems. Recognising the benefits of 3D technology, which are universally accepted across the AEC industry, it is surprising that 3D technology has not penetrated the construction industry to a much greater level.
