By leveraging information obtained from the dense 3D surface data of a laser scan, Actus3d will create topographic maps of linear surfaces. These forensic studies clearly illustrate deviations from horizontal and vertical plane. In existing buildings it helps to quickly identify problem areas and extent of surface movement. In new construction it will provide essential information on both existing and new substrates, allowing corrective measures to be implemented where needed.
Rubble masonry walls can be checked for compliance within a set tolerance dimension, difficult to do using conventional spot elevations. Mapping of floors or site areas can help verify quantities of cut or fill required. Similar processing of the data can check structural steel spans for deflection and square.
