Taylors apply 3D Reality Modelling as evidence in successful VCAT case
Taylors have applied 3D reality modelling created from drone data as evidence at Victorian Civil and Administrative Tribunal (VCAT) to prove the viability of a proposed residential extension, with the client winning the case.
Taylors, on behalf of their client, provided expert evidence in a VCAT hearing in relation to a building extension. Using cutting-edge drone technology, Taylors was able to create an accurate 3D representation of how the extension would look once completed, proving that it is consistent with the character of the area and that there would be no negative impact on the surrounding environment.
Taylors Urban Development Planning Manager Matthew Law, who presented the case to VCAT, said the reality models were a step above anything VCAT had seen in a case like this, as previously only 2D photo montages had been used as evidence.
“Previously you would only see a flat 2D photo in which the proposed development was superimposed onto. If someone at the hearing had a question about the development that wasn’t shown in the photo, the issue couldn’t be addressed,” Mr Law said.
“With reality models, you have an infinite number of angles and perspectives and you can view exactly what the development will look like in the environment, removing any doubt that is created by the opposing parties.”
Collecting data using drones
Images captured by a drone were combined with conventional surveying to produce a reliable and accurate 3D reality model.
A Quadcopter drone was flown around the site to capture hundreds of aerial images and a site survey was also conducted to ensure the accuracy of the 3D reality model.
Taylors 3D Modelling and BIM Manager, Alastair MacColl, who prepared the reality model and provided the expert evidence in the case, said 3D reality models still have the same high level of accuracy as other ground surveys Taylors performs, but with the added benefit of allowing the user to interact with it and look at it from any location.
“At Taylors, we are spatial data experts with a high level of understanding about data accuracy. We’ve developed a methodology that when combined with conventional surveying, yields accuracies that are comparable with typical Rescode surveys.
