Remote sensing techniques – the distanced procurement of information about objects or areas with indirect contact sensors – can improve the speed, accuracy and cost effectiveness of surveying for construction in, says University of Pretoria Department of Engineering and Technology Management senior lecturer Schalk Grobbelaar.

Remote sensing techniques help to ensure effective production during the important phases of construction. Throughout the construction process, this technique can ensure that fewer mistakes are made, which consequently reduces costs and construction time.

“It is especially useful in brownfield projects that do not have accurate ‘as-built drawings’ of existing infrastructure,” highlights Grobbelaar.

From a safety perspective, the biggest potential is surveying difficult-to-reach or hazardous locations, which “can improve the safety of mines by identifying structural weaknesses in places that are unsafe or inaccessible to humans”.
