What is a 3D Survey?
3D Laser Scanning Operations Manager
It may be easy to initially consider a 3D survey as simply another architectural design model, however this is far from the case. Where an architectural 3D model will represent spatial allocations, and dimensions for an individual building, it will not necessarily accurately represent aspects of the project such as; the land boundaries, neighbouring properties, accurate levels’ elevations, or the distances and exact orientation within the boundary.
The reason for this?
It’s extremely difficult to collect this type of information, or measure in this level of detail during a site visit without the correct equipment. It can be equally challenging to then later adapt a 2D PDF or DWG survey into a 3D digital space.
This is where having a trusted land survey, like C&A Surveyors, can come in really handy, as they will arrive on a site with the correct equipment, and take care of the accurate modelling required to deliver an ‘As-built Survey’. For more on As-built Surveys, see our other article What are the Benefits of 3D over 2D Surveys?
Why should you choose a 3D survey over a traditional 2D survey?
3D surveys take the guess work out of a project or specific site. This is in regards to accurate and detailed measurements of all objects found within a surveyed space. C&A Surveyors is able to deliver site information, such as boundary offsets, with far greater accuracy, which will be supplied directly to the architect. This means the architect doesn’t need to manually measure a site, or manually generate a 3D representation of the site themselves, in their architectural software.
Instead, they are supplied with a 3D model in various formats to suit all regularly used 3D design/ BIM software, along with all of the traditional 2D survey files that they are used to receiving. This greatly reduces the architects modelling set-up time, saving them time, and you the customer money, ensuring a more accurate final output model to begin designing
with, which has been built upon a highly-accurate initial data set.
Our 3D scanners can record 500,000 points per second, for higher levels of detail, fidelity, and accuracy in the data we collect. Our in-house modelling team is then able to create a highly accurate 3D model by assigning each individual point with an easting, a northing and an elevation, which is equivalent to an X, Y and Z coordinate in 3D modelling software. Each of these points allow our team to then model in place, all of the other elements, structures and features of each site we survey.
The entire 3D Survey, and 3D modelling process is conducted In-house, ensuring that only the best quality is delivered to all of our clients. This includes the; scanning, data processing, 3D modelling, documentation drafting, and Quality Assurance procedures are implemented for every project.
