3D Laser Scanning for Clash Detection & Prefabrication

3D laser scanning captures as-built site conditions with millimeter precision, helping to identify potential clashes, prefabricate components, and plan a flawless installation. Data collected can be shared across project teams to have one single source of information. Accurate design planning and team communication minimizes clashes, installation problems, and rework. This saves time, money, and headaches by preventing costly modifications in the field.

3D Laser Scanning for Clash Detection

Clash detection is the process of looking for potential clashes, interferences, and collisions between existing and newly designed elements prior to installation. It is a process used in many industries to ensure the smooth installation of components, minimizing downtime and re-work.

After completing a project design, errors are possible. The process of clash detection involves placing a design model into a 3D laser scanned as-built environment, where clashes in design work can be detected. One can virtually see what overlaps in the project design plans. Identifying clashes in the design stage saves costly material expenses and time delays.

3D Laser Scanning for Prefabrication

Prefabrication is the practice of assembling components of a structure in a factory or other manufacturing site, and transporting complete assemblies to the construction site where the structure is to be located. For prefabrication to be successful, accurate component dimensional and location information is crucial. 3D laser scanning allows clients access to exact measurements to make fundamental calculations of building components for offsite manufacturing.

Any deviation in a prefabricated component may cause an assembly failure, leading to rework or reconstruction that can increase project duration and cost. By incorporating millimeter-accurate laser scan data into prefabrication workflows will ensure that offsite construction elements fit perfectly in the installation space.

3D laser scanning can also be a critical part of the estimating process. 3D scanning can provide valuable details to estimators to understand the site’s context, evaluate labor and material costs, and prepare project timelines.

Human error is possible. 3D laser scanning proves its value throughout construction projects minimizing clash detection and prefabrication errors before project build-outs.
