Scan to BIM process involves the laser scanning of an old structure or monument in order to have a refurbished rendered Building Information Model. Although laser scanning is the starting point of the progression, it only encompasses one facet of the practice in its entirety. The technology includes the following steps:
The firms send professionals whose main aim is to extract as much information from the as-built proposed location. Scanning is then carried out to set up control markers that are permanent as well as temporary 3D inspection controls. These inspection controls will later be used to set up constraints for the scan and facilitates the point cloud to be scrutinized for precision later on.
After setting up parameters in the proposed location, scanner beams are projected onto various segments of the building. Every surface is scanned, but laser beams are primarily thrown on to each beam, pillar, pipe and service from different elevations and angles to learn about each and every niche of the structure to have a whole and complete understanding of it. As soon as the laser beam hits any surface, it returns the information as well as the point cloud data that essentially comprises the base of the 3D model.
The spatial information and the surface data obtained from laser examination is checked, processed and supervised at customary pauses. It is further compiled so the scan point cloud data can be cataloged collectively and filed and compared against inspection management to ensure superiority as well as correctness. Once this is completely sorted out, this knowledge can be given to architects, engineers, and construction handlers to facilitate the production of Building Information Models.
Building and modeling process
This stage completely relies on and utilizes BIM software to expand upon as-built drawings and models from the point cloud data of the ancestral structures. Autodesk Revit is outfitted in such a way that it can comprehend the data and permit modelers to coalesce, investigate, and present the information through first-rate 3D models that utilize the point cloud data to correspond to the composition as accurately as achievable.
The scan to BIM process combines the 3D models for new and renovated components of a structure. The models thus obtained are inclusive of all current as well as potential building rudiments such as porches, pipes, beams, columns, ceilings, internal landscaping, space management, external walls essentials and Mechanical , electrical and plumbing fittings. Point cloud scanning to BIM modeling is extensively documented to be more exact than conventional inspectional data that are accomplished using measuring apparatus.
