Terrestrial laser scanning – effective technology for creating building information models

Abstract

Building information modeling is a process for creating and managing information on a construction project across the project lifecycle. The lifecycle of building includes also a stage of reconstruction and technology of terrestrial laser scanning is an effective method to create 3D building information models of the real state. Laser Scanning is a non-contact technology that captures the shape of physical objects and gives exact representation of the building geometry. Current scanning technology has the ability to send out thousands of beams per second, resulting in a ‘point cloud’ of data. This study offers an overview of the survey planning stages, field operation, processing of point cloud data and the possibility to integrate data into the building information modeling.
