An unmanned aerial vehicle (UAVs), also known as drone technology, is used for different types of application in the civil engineering. Drones as a tools that increase communication between construction participants, improves site safety, uses topographic measurements of large areas, with using principles of aerial photogrammetry is possible to create buildings aerial surveying, bridges, roads, highways, saves project time and costs, etc. The use of UAVs in the civil engineering can brings many benefits; creating real-time aerial images from the building objects, overviews reveal assets and challenges, as well as the broad lay of the land, operators can share the imaging with personnel on site, in headquarters and with sub-contractors, planners can meet virtually to discuss project timing, equipment needs and challenges presented by the terrain. The aim of this contribution is to create a general overview of the use of UAVs in the civil engineering. The contribution also contains types of UAVs used for construction purposes, their advantages and also disadvantages.
Construction project management is difficult process and important part of efficiency and productivity in construction industry. Currently, construction industry is increasing demands on technology, environmental and social construction parameters in the context of maintaining the balance of economic efficiency and sustainability of the construction and realization of buildings. Progressive technology as knowledge systems and building information modeling are the supporting tool for achieving this. Building information modeling is a progressive intelligent 3D model-based process that gives architecture, engineering, and construction professionals the insight and tools to more efficiently in planning, designing and buildings and infrastructure managing. Knowledge and building information modeling technology include a lot of functions and opportunities for better and easier way to achieve project goal and affect to construction project management process. Research discusses the issue of construction project management trough building information modeling and knowledge technology. The main aim of the paper is to analyze impact of these technologies on efficiency in construction project management.
Laser scanning is the most modern technology for high quality focusing on real objects. 3D laser scanning technology allows the space digitizing of objects which means transferring different objects from the real world into a 3D digital environment where they can continue to work. 3D object scanning allows enhancing the design process, speeds up and reduces data collection errors, saves time and money and thus makes it an attractive alternative to traditional data collection techniques. This technology has wide application and it can be used for surveying of various objects such as buildings, factory buildings, machinery, equipment, engineering networks and also cultural monuments or statues. The result of a scan is a 3d model point cloud which represents threedimensional image of scanned objects and complex shapes. The aim of the paper is description of methodology of the work with 3D laser scanner Faro Focus X130 from Faro Company on the real building object - historic greek catholic church. This paper describes the methodology of laser scanning, describes the specific step during scanning and describes the possibility of create 2D documentation from 3D model point clouds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
