3D Laser



terminal recap chchBoys


A 3D laser scanner is a surveying instrument that scans structures.  It literally captures millions of points on the surface of the structure.  In the right hands those millions of points will be captured to survey accuracies.  The output is called a point cloud and forms the basis for the key products we offer.


Point Cloud – reality capture

  • Bring the site to your workstation
  • Explore and measure
  • Snapshot in time

Point Cloud — A point cloud is a set of data points in a three-dimensional coordinate system, these points are usually defined by X, Y, and Z coordinates, and represent the external surface of an object. Example 1: Our Surveyors have been out all hours to capture Auckland Airport with 3D Laser Scanning in preparation for the Terminal Development Project.  Click here to read more. 


Analysis – fit and form

  • Find deformation
  • Prove compliance
  • Monitor change

Hi Definition Analysis — Non-conformity or deformation issues are quickly and easily identified on structures such as tanks and piping, buildings, roads and slabs. This can be done faster and easier than previously possible.  Scanning allows the whole structure to be analysed rather than discrete points. This means better analysis, better reporting and less risk. Example 2: Read more about leaky apartments analysis.  


2D Drawing – connecting the dots

  • Minimise mistakes
  • Survey accurate
  • Create plans, elevations and sections easily

Example 3: 2D Drawings — Our 3d modeller created a traditional 2d drawing set along with an integrated point-cloud model that the client could view quickly & easily online. The drawing set, along with BIM viewer & Webshare web hosted 360° photometric viewer were delivered to enable the client to begin the design.


3D Model – your digital reality

  • Richer data
  • Less risk
  • Faster and more accurate

Example 4:   The ability to model accurately from the point cloud, and then toggle the cloud on an off during design is of huge benefit to designers. It is designing in the real world from your desktop. In this example 3D documentation of a heritage listed building that had undergone several refurbishments through time was required by all parties to begin redevelopment design, read more.


Visualisation – explore your design

  • Built from the real world
  • Incredible detail
  • Legally verifiable

Example 5: Visualisation— an underground carpark with five subterranean floors was surveyed using 3D Laser scanning. The client was looking for dilapidation and needed highly accurate geometry of the site. 3D cutaways of the areas of interest were then produced. This allowed our client to mitigate design risks within the 3D realm, in an environment where no-one is left behind in the conversation.


Asset management

Facilities managers and property managers need information about each site they are responsible for. Industrial and infrastructure plants can be highly complex.  The ability to record extremely accurate measurements for each structure on-site is now easy with 3D laser scanning.  The scans reveal not only what is actually there, they can also be interrogated for deformation, reviewed for refurbishment and improvements and used for stocktaking purposes.  Plus there is the benefit of scanning on hazardous sites from a health and safety perspective.



3D laser scanning records data with millimetre accurate point clouds, providing a record of structural information and services.   Existing buildings and peripheral structures can be compared to a designed model or drawings and interrogated by everyone involved – the architects, engineers, project managers, constructors, clients etc.  You’ll know if the new design works (or not) and can assess various options in the digital world, saving time, money and frustration.

What can 3D Laser scanning do?

  • Information, rich and complete enough to drastically reduce the unknowns in your project environment.
  • Communicate, in a 360° photometric viewer with the power to measure, notate and append information to all stake-holders.
  • 3D Record, of incredible detail of your site. Able to be interrogated for ongoing maintenance and design.
  • Digital Model, to your specifications enabling you to test your designs and fabricate off-site.
  • BIM, in confidence with a robust, complete data set with which to move forward in Building Information Management.  Click here to read more.

  • Fewer revisits; with scanned data there is a reduced need for site re-visits.
  • Stunning results; our Envivo emphasis on quality means you get stunning visual results in 3D
  • Service; we are passionate about this product and look forward to working with you at your site nationwide.

3D Modelling

3D modeling is the process of developing a mathematical representation of  any three-dimensional surface or object via specialised software.  The product is called a 3D model and can be displayed as a two-dimensional image through a process called 3D rendering or used in computer simulation.  The model can also be physically created using 3D printing devices. Point cloud data is loaded into software for the project in hand, this could be AutoCAD 3D; Civil 3D, Revit or Sketchup.

Our modelling team then convert the point data to either a 3D surface or a solids-based model. DELIVERABLE — model output specific to your requirements.
