Scan-to-BIM Basics: 12 steps to bring an existing building into BIM

Written by Bulent Yusuf | Jun 2, 2020

Let's explore the end-to-end process of a standard scan-to-BIM project, and learn the best practices for bringing existing buildings and structures into a building information modeling (BIM) framework.

This article outlines the best practices for bringing existing buildings and structures into a building information modeling (BIM) framework – otherwise known as scan-to-BIM – and unpacks some jargon along the way.

Uses for models made with scan-to-BIM range from as-built documentation to project renovations. They're also useful for comparisons with the original or as-built plans, topographic registration, and more.

If you're a laser scanning professional, you'll know that scan-to-BIM is attractive to your clients because it mitigates the margin of error at the survey stage, and reduces survey times and associated costs.

It can also cut down the time spent at the site by capturing the entire location in one session. If done properly, your customers will have an accurate virtual representation of their building, complete with a set of up-to-date models and plans.

Here, laser scanning professionals can find information on handling scan-to-BIM projects in 12 steps, based on recommendations from Autodesk University.

The stages of a scan-to-BIM project

Broadly speaking, every scan-to-BIM project consists of four stages:

  • Data capture and processing...
  • Clean-up...
  • Modeling...
  • Quality assurance...
