3D Building Surveys 2017: A New Dimension in Surveying
In 3D building survey, high definition survey like setting up instrument, measurement of height-of-instrument, and instrument orientation. When it comes to 3D building surveying, any exposed surface is remotely captured within minutes forming a dense and accurate 3D point cloud. Project designers directly benefit with a number of details provided by laser scanners, giving a scan rate of 50,000 points per second, covering a larger area in a shorter period of time. The resulting data undoubtedly allows more extraction of built-in information needed for building higher confidence within the design team.
There are many uses of 3D laser scanners most especially in surveying such as planning and design stages, site model 3D printing, rights of light reports, topographic surveys, detailed elevation surveys, artefact archives and heritage buildings, bidding process estimates, building information modelling, measured building surveys, as-built surveys for construction and engineering projects, volume surveys, MEP surveys, monitoring land deformation, archaeological sites surveys, accident investigation, post-construction scans for facilities management, and roads, tunnels, bridges, bridges, railways and quarries surveys. For safety, the 3D laser scanner can be remote, in order to avoid hazards and obstructions. It is the ideal instrument for surveying potentially hazardous and inaccessible places such as railways, public roads, high-rise and general public places. 3D laser scanners are versatile, multi-purpose, with high efficiency and accuracy to handle civil engineering, building, and plant projects. To allow the design team to obtain adjacent building heights and crucial dimensions, a 3D laser scan can be commissioned prior starting the work on site for assisting with logistics.
With 3D laser scanning technology, digital surveys present a more a comprehensive data capture service carrying out point cloud surveys. Everything can be mapped virtually with a 3D scanner, from very small industrial components to large scale city models. 3D laser scanners come with different capabilities, ranges, durability, speed and accuracies, and when a site or item is scanned, accurate 3D data or point cloud is generated. Most 3D scanners record surface reflectivity generating an intensity value, with inbuilt cameras, applying colour in the form of an RGB value in each point. In a 3D laser survey, the instrument has a superior accuracy and fast data capture rate, so it rapidly replace traditional methods of surveying. Because of innovation and technology, surveying works are made simpler and easier, because of the utilization of 3D laser scanners for faster, accurate, reliable and precise results.
