3D Survey of a Neoclassical Building Using a Handheld Laser Scanner as Basis for the Development of a BIM-Ready Model

Abstract

This paper explores the application of two widely-used digital technologies, Digital documentation using laser scanning and Building Information Modelling (BIM), in the case of neoclassical buildings. Laserscanning with a handheld scanner was used for the 3D documentation of a neoclassical building in Athens, including exterior and internal spaces. The resulting point cloud dataset constitutes the primary survey record of the neoclassical building in its current state (as-existing). Finally, a BIM-ready model of the existing structure was proposed as an alternative method for the production of coordinated 2D drawings and facilitating requirements of subsequent development of the project.
