ABSTRACT
This chapter discusses the state of the art for operating and maintaining facilities, describing the prevailing methods of building maintenance. It highlights their limitations with proposed alternatives, such as 3D Geographic Information Systems (3D GIS) to enable the spatial analysis and static visualisation of critical of query outputs and 3D laser scanning technology for obtaining the digital information of existing buildings for construction maintenance. Typically, construction facilities require maintenance and occasional repairs on a regular basis, due to deterioration and aging. This is to keep them functional and in a satisfactory appearance. The chapter considers Decision Support System and delves into the integration of the 3D laser scanning technology with GIS system for building maintenance. It provides the existing methods of building maintenance and their limitations are explained in order to justify the integration of the 3D-GIS and the 3D laser scanner systems.
