Powerful Points Of 3D Scanning

Complex building shapes and highly detailed facades can now quickly and easily be scanned in three dimensions thanks to new technology in the Australian and New Zealand market being utilised by Realserve.

“We can provide a rapid turnaround of data on any project from a simple floor plan to complex building elevations using specialist non-contact laser measurement equipment and the latest 3D laser scanning technology,” explains Realserve business development manager James Sawell.

It is precisely this nascent laser technology that is becoming the weapon of choice in the survey arsenal that Realserve can offer to Architects and Builders, enabling them to swiftly interrogate the as-built environment to a previously unknown level of detail.

The scanning process creates a dense model of 3D points known as a ‘pointcloud’ comprised of millions of points of information. This enables the scanner to measure complex and highly detailed building objects very quickly, allowing for scans to be carried out in environments where traditional surveying would be impractical or the level of detail required is very high, explains Sawell. This high level of detail is possible with 3D scanning forming a key benefit over traditional techniques.

“3D scanning captures everything which is visible in the field of view and records it. Multiple scans of the subject site may be required and these scans are merged into a single three-dimensional representation of the area and post-processed within various software packages. From there the client may utilise the data as a pointcloud model, by directly inserting it into their CAD drawing or they may choose to reduce the scans into a traditional 2D drawing set or create a 3D CAD / REVIT model,” he explains.

In broader terms the technology is used for architectural modelling, civil engineering and existing conditions measurements.

Just some of the applications include producing 3D documentations of interiors and building sites, road and landscape features although Sawell says clients are constantly coming up with new ideas as to how the technology can benefit them. Realserve has already used 3D scanning on heritage churches and large department stores.

“We have used it on a project where the architect was based in Europe so obviously couldn’t get to the site easily. The scan meant that he had all the information he needed as if he was physically visiting the site,” explains Sawell. “Other interesting uses include a job where Realserve 3D scanned the low hanging limbs of some trees protected by a conservation order, for the purpose of installing a stage under them. By having a real life model of the environment the architects were able to harmonise their design and the arborists were satisfied no harm would come to the trees.”

Realserve was founded in 2000 as a means of delivering a vital single source measure and draw solution for commercial real estate agents and architects.

Other services offered by the company include:

  • Land surveying services,
  • Detailed marketing floor plans for commercial property,
  • Site plans and concept plans,
  • As-built/existing condition plans,
  • Reflected ceiling plans,
  • Building elevations and sections, services plans,
  • Evacuation diagrams
  • Lettable area surveys.

“If you can see it – we can measure it,” says Sawell. “Our aim is to be the national leader setting standards in providing survey accurate plans in a consistent, efficient and innovative approach.”
