Three-dimensional model database for space utilization and planning using terrestrial laser scanner data

Abstract

Space management is not only concern about the quantity but also the quality of the space allocated as well. It is a waste of resources to have unused or underused space. Several factors influencing the quality of space management are limited information on rooms and spaces and number of occupants filled in a room does not reflect the room capacity. The difference between this research and others is in the utilization of Building Information Modelling (BIM) tools for indoor space management. By using BIM tools for space utilization and planning, user can freely design the 3-dimensional (3D) models either based on point cloud or design measurement. Furthermore, BIM tools provide users the power to manage and analyze the 3D model data in the database system. This research were conducted to achieve three objectives; to generate 3D models of existing indoor space and furniture using terrestrial laser scanner captured data; to create 3D model database system; and to manipulate the 3D model data to assist the decision-making process in space utilization and planning application. This research utilized the created 3D model which can provide the true geometry and condition of a room and by acting in accordance with the International Building Code, it can be used to tackle the problem of room capacity with respect to health and safety requirement. With geometrically accurate 3D model, it can give the right information for the analyses of functional area allowances, occupant load and exit capacity. Method proposed in this research can ease the process of space utilization and planning by having the ability to analyze space requirement and manage 3D model database in one software.
