Kassel, a dynamic city in Germany, faces significant construction projects driven by the growing demand for residential and industrial spaces. The development of the Langes Feld business park, spanning 136 hectares with a construction volume exceeding 70 million euros, stands out among these endeavors. To ensure efficient progress, the municipality utilizes Leica Geosystems' UAV solution for real-time monitoring. Coordination of 40 construction workers and 18 earthmoving machines demands meticulous planning and continuous information flow. Surveyors provide accurate geo-data and monitor mass movement to promote sustainability and efficiency in decision-making.
