3D modelling and monitoring of engineering objects, based on the use of Terrestrial Laser Scanning image, provides ideal opportunities for the study, design and monitoring of these infrastructure works. The object of the study is the Bridge on Shkumbin River, an integral part of the existing railway infrastructure Rrogozhinë-Lushnje. This study reflects the necessity of using this technology due to the very high rates of development of instrumental measuring geodetic technologies, the need to increase monitoring rates, guaranteeing maximum operational safety in all projects where these facilities are applied. This method, due to its application in geodetic motorization technology, distance receiving information technology, without being required to provide the facility, digital photography technology through the digital cameras installed in them and due to advanced processing programs with photogrammetric graphics, results efficient, fast and incredibly accurate. As a result, the product offered entirely based on cloud-point pixels with a resolution of the millimetre order is a 3D format drawing rendered with maximum and complete dynamic accuracy needed for studies, monitoring, and rehabilitation projections of these very important infrastructural engineering works.
