In modern and intensive agriculture conditions, the importance of soil levelling is high.. It's effects are found in providing optimal and equal conditions to the crops, during yielding and growing. In areas with water excess, the soil levelling provides an appropriate water runoff, ensuring a better water management. The levelling works design is based on land surveying performed for surface units which are going to be ameliorated. Based on the survey plans, the following issues are settled: - the alignments which need levelling and the necessary optimal slopes from the efficient runoff point of view; - the areas of digging/filling, depending on optimal slopes, to minimize the volume and transport distance of the ground. The calculations are performed using “Least-squares method” or other approximate methods. Unfortunately, the use of these methods needs long time and their accuracy and effectiveness are limited. The paper gives a more effective technology to perform levelling works, which is based on the newest technology used in environmental engineering. The method is tested in Land Recovery and Environmental Engineering Faculty, and consists in using the following 3 elements of high novelty: -replacement of the classical survey with modern scanning methods using LASER technology devices; - use of modern GIS applications, developed by ESRI International, for data processing, combined with efficient CAD applications, developed by Autodesk Inc., world widely utilized; - generation of a 3D model, based on the information collected and processed in accordance with the above mentioned steps. Then The model is sent to dirt mover machine, by the aid of an operating device, using LASER technology. This way, the ground work machine can model the land with high accuracy, low costs and minimum fuel use.
