For the measurement of areas and buildings, Lindner Group also offers digital as-built documentation: With the help of a 3D laser scanner, measurements are created quickly, easily and precisely at 360° angles.
Modern 3D Laser Scanning Technology
Facades as well as floor plans or interior and exterior views can be efficiently measured with a 3D scanner: In doing so, the laser scanner first casts an invisible beam onto the object. These laser beams are then reflected back, creating a point cloud – around one million points can be captured per second. These are then further processed with suitable software (e.g. Revit, AutoCAD, MicroStation) into 3D models or 2D sections and ultimately serve as a basis for further planning. Among other things, the digital as-built survey is used for shims or complicated contours.
Mobile vs. Stationary
Both mobile and stationary laser scanners are suitable for digital as-built documentation – these differ primarily in terms of the time required for measurement and the precision: a mobile laser scanner can record distances of up to 100 m relatively quickly and easily with an accuracy of 1 cm. The stationary scanner, on the other hand, must be set up at regular intervals – therefore, it achieves an accuracy of up to 1 mm.
Analogue becomes Digital
Compared to a classic manual measurement, the digital as-built documentation at Lindner offers several advantages: A 3D scan saves costs and simplifies processes. The measurements are more accurate, the information density in the plans is higher and even masses can be determined – thus reducing the susceptibility to errors in construction and planning. Especially supplementing 2D documents such as floor plans, elevations and sections with 3D models or panoramas offers many benefits. These data can also be integrated easily into classic workflows and therefore offer a significant reduction in workload for architects and specialist planners.
Advantages at a Glance:
