Building the Bigger Picture Piece by Piece  

Model-based design saves time and money

Model-based design involves the production of three-dimensional structure models used on site at virtually all stages of civil engineering and road-building projects. For example, the drivers of excavators look at the models while working in their cabs and dig referring to a digital plan and construction machinery positioning. This requires precise RTK-GPS, which is achieved in the site area using base stations that send repair messages to the machinery. In this way, the diggers can build structures at the site to an accuracy of a centimetre.

Model-based work saves time, materials and other resources, as the digger is able to excavate directly to the required depth without digging any extra material to be on the safe side. In this way less backfilling and transport machinery are required and the work proceeds quickly.

At the same time too, there is less need for measurements to be taken of the terrain, which is also a safety consideration. The increase in the use of automation has shifted its focus of measuring work to the updating of models, the supervision and calibration of the precision of measurements of construction machinery, and predictive quality assurance.

At Destia, model-based production is used at over 30 sites every year. Destia has now established almost 200 sites using construction machinery automation.
