If you need a structured model for multi-discipline coordination, renovation design, or lifecycle use, <a href=\"\/en\/scan-to-bim\/\"><strong>Scan to BIM<\/strong><\/a> is the better investment.<\/p>\n<p style=\"margin: 0;\">Not sure? Use the checklist below most rework happens because teams order \u201cBIM\u201d when they only need drawings, or order \u201cCAD\u201d when they actually need a coordinated information model.<\/p>\n<\/div>\n<p>Laser scanning and point clouds have made as-built documentation faster and more reliable than traditional site measurement. But once you have a point cloud, the next question is usually the same:<\/p>\n<p><strong>Do we need Scan to CAD or Scan to BIM?<\/strong><\/p>\n<p>Many projects waste time and budget at this step not because scanning is difficult, but because the <strong>output is specified incorrectly<\/strong>. Some teams ask for BIM when they only need a handful of 2D drawings. Others request CAD drawings and later discover they need a coordinated model for MEP clashes, renovation design, or asset information.<\/p>\n<p>This guide will help you choose the right deliverable by comparing outputs, typical use cases, cost drivers, and a practical decision checklist you can share internally.<\/p>\n<p><img decoding=\"async\" class=\"lazyload alignnone size-full wp-image-33345\"
