Demonstrating the usage of GCL software for quatity take-off of building in a virtual high-rise building case

With the acceleration of the process of global revolution in science and technology led by information technology, the human society is in a gradual transition from an industrial society into an information society. This has already become a major trend in the informatization of various industries including the field of engineering cost. In order to meet the requirements of the development of its own industry, the Chinese construction industry is strengthening its informatization and vigorously promoting the application of information technology. This paper describes the usage of GCL software in a high-rise building case, which was developed by Glodon company, had released to be used and is prevalent in high performance computing quatity take-off. Based on 3D modeling GCL Software can calculate automatically quatity take-off of building processing automatically deducted relations between components. Its core is the construction process of the modeling for building, which is divided into such steps as setting the floor elevation, establishment of axis network, establishment of building components, drawing component, formation of floor, building formation. After three-dimensional model of buildings built the quatity take-off of building can be automatically calculated, which can be seen in output forms. In this paper we present two case studies. The results of the study identify higher efficiency in the GCL software calculation for quatity take-off of building than manual calculation. This study also revealed that GCL software can well meet the bid requirements quickly and accurately.
