CSD Site is the on-site scanning and survey operations of CSD Group Australia Pty Ltd (CSD Group). The team offers survey works of up to 2-millimetre (mm) accuracy, ensuring accuracy of design at pre-construction stage. 


Established in 2013, CSD Group has worked on projects in Australia, Hong Kong, New Zealand and Papua New Guinea. It offers a suite of services for construction projects, from pre-construction design works to on-site solutions. 

CSD Group has four units: CSD BIM, CSD Drafting, CSD Engineering and CSD Site.

Digital layout


Using the Leica iCR80 Robotic Total Station (RTS) linked with our Tekla models, we can provide layout services and site set-out assistance to place holding down (HD) bolts, chemsets, position ferrules, site drilling and more.

With our complete and comprehensive laser layout service, no survey dimensions will be missed, no site revisit will be needed and expensive site layout issues are eliminated. This also makes retrofitting of structures as easy as building new infrastructure. 

Our laser layout service includes:

  • laser set-out of HD bolts and chemset locations on site using the model coordinates with up to 2mm accuracy; and

  • import of site points back in the model for as-built reviews.

3D laser scanning

and point cloud


Using Faro 3D scanners and software products, we are able to collect millions of survey points, capturing vital information and dimensioning required for projects.

A complete and comprehensive site survey is accomplished at one time, with no need for a site revisit. This makes retrofitting of existing structures as easy as building new ones and helps eliminate costly site layout issues.


Our laser scanning covers: 

  • up to 2mm accuracy on the 3D photo scanning of existing structures;

  • the capture of site markings and points of interest; and

  • taking measurements from the captured scan model.

Fabrication verification

Construction verification

Another recent innovation which has proven to save significant project costs is verification in the field. Using our scanners on the construction site, we can use CAD models to analyse in real time multiple construction trades to determine correct placement of all assets. Use cases can be concrete flatness and positional checking, pre-cast panel positioning and plumbness, beam pre-camber and positional checks and outrigger/complex item levels.


If there are mission critical items on site, they should be scanned to ensure a correct fit before it becomes a bigger expense.

Fabrication verification


Utilising our 3D laser scanners in the workshop is an emerging technology. Coupling our point cloud scans with our verification software, we can analyse real world fabrication objects against the CAD models provided by the drafting team to ensure fabrication is correct on members prior to sending for painting/galvanising.


The use cases for this are complex trusses, pre-cambered members and curved members, which often prove difficult to verify quickly in the workshop environment.
