Laser scanning is the most wide spread technology used for conversion to as built models of existing structures or buildings under construction. It is an efficient technique in which the actual site conditions can be efficiently monitored and made into compliance.

For existing structures, laser scanning is carried out and the point cloud is converted into as built information rich models through BIM Modelling. For construction under progress, regular laser scanning is done at different stages of the project to ensure that the model is corrected with on site progress in a stage-wise manner. Also, it helps to record the MEP components which are hidden after construction and do the relevant changes related to the site

As-built models provide an accurate representation of the facility and its systems, enabling facility managers to identify equipment and components that need maintenance or repair. With accurate as-built models, maintenance teams can quickly locate and diagnose issues, reducing downtime and costs. When a facility needs to be renovated or expanded, as-built models provide an accurate starting point for design and planning. Facility managers can work with architects and engineers to modify the as-built models, ensuring that the design meets the facility's requirements and adheres to local codes and regulations.
