A laser scanner is used to capture accurate 3D scan data in the form of point clouds of any building structure, which then, with the help of 3D BIM software, is converted to As-built models to depict the designs in the actual context.<\/span><\/span><\/p>\n<p><span style=\"color: #000000;\"><a style=\"color: #000000;\" href=\"https:\/\/www.qecad.com\/scan-to-bim-services.php\"><span style=\"font-weight: 400;\"><strong><span style=\"color: #0000ff;\">Scan-to-BIM services<\/span><\/strong><\/span><\/a><span style=\"font-weight: 400;\"> are helpful for projects relevant to restoration, retrofitting, and refurbishments. It helps in grabbing reliable and accurate information that can be used during construction. It enables data-rich and constructible workflow with the accuracy of measurements fetched from 3D laser scanners. Architects, engineers, and general contractors use laser Scan to BIM techniques for evaluation of the existing site, easy procurement, operations, and facility management, as well as assessing the energy efficiency aspects of the structure.<\/span><\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"color: #000000;\"><span style=\"font-weight: 400;\">\u00a0<\/span><span style=\"text-decoration: underline;\"><b>Workflow of Scan to BIM Conversion Process<\/b><\/span><\/span><\/p>\n<p><span style=\"font-weight: 400; color: #000000;\">The whole Scan to BIM process consists of the below significant stages.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"text-decoration: underline; color: #000000;\"><b>1) Identifying the Requirements<\/b><\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400; color: #000000;\">The first and foremost step is to encapsulate the data, i.e., gather all the information relevant to 3D BIM modeling. This includes:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400; color: #000000;\">Defining and documenting the actual scope of work<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400; color: #000000;\">Identifying the level of detail (LOD 100- LOD 500) required<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400; color: #000000;\">Defining required building elements<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400; color: #000000;\">Defining geometric and non-geometric attributes<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400; color: #000000;\">Defining required deliverable formats<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400; color: #000000;\">Determining the Tolerance level, etc.<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><span style=\"text-decoration: underline; color: #000000;\"><b>2) Scan Planning<\/b><\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400; color: #000000;\">Under Scan Planning, the parameters or the attributes are determined beforehand, as this may prove beneficial before performing a 3D scan.

This scanning device has a laser rotating at high speed, and when the laser beam hits any surface, its position is recorded as coordinates (x, y, z) termed \u201cpoints.\u201d The collection of such points is mapped together, depicting the actual digital picture of the site from multiple views, termed a point cloud scan.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400; color: #000000;\">This point cloud scanning process can be performed using techniques such as 360 Degree scans, Time of Flight Scans, and Phase-based Scans using varied scanning tools like Faro, Trimble, Leica, etc.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"text-decoration: underline; color: #000000;\"><b><span style=\"font-weight: 400;\"><img decoding=\"async\" loading=\"lazy\" class=\"alignnone wp-image-3294 size-full\" src=\"https:\/\/www.qecad.com\/cadblog\/wp-content\/uploads\/2022\/11\/Scan-To-BIM-.jpeg\" alt=\"Scan to BIM \" width=\"2500\" height=\"1667\" \/><\/span>4) 3D Modeling<\/b><\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400; color: #000000;\">Once we get the point cloud scan of the structure, it is then registered and imported into a scanning software like Autodesk\u2019s Recap to extract the relevant information about the structure, which the AEC professionals can use in numerous ways. This is termed Deciphering the point cloud data. The information includes:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400; color: #000000;\">Point cloud scan file format (.rcp, .rcs)<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400; color: #000000;\">Coordinates<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400; color: #000000;\">Grid, Level, and Model alignments<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400; color: #000000;\">At this stage of the Scan to BIM process, we get our As-built model with the necessary information, which later can be used for remodeling, redesigning, and renovations.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"text-decoration: underline; color: #000000;\"><b>5) Quality Control<\/b><\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400; color: #000000;\">Once we have our 3D model handy, the last stage of Scan to BIM is performed, which is to thoroughly check out the quality with the help of Revit plugins.
