This paper presents the implementation of Building Information Modeling (BIM) technology in the development of a lifecycle cost-estimating tool. The IFC (Industry Foundation Classes) model as an interoperable building information model has been adopted as the central data repository to deliver the integrated information of building designs from CAD design systems into the lifecycle-costing database. In this paper, the conceptions and relevant factors, which could affect the LCC estimation, have been introduced. The problems of current LCC applications have been identified as the lack of LCC data and the complexity of LCC exercises. The software application of IFC models and relevant auxiliary are depicted as a solution of the problem identified. The lifecycle costing tool is a part of the nD Modeling tool and as such is based on its integrated interface prototype toolkit and is able to holistically present an IFC model into a 3D virtual reality view, a tree-view and a list of element properties. The functions and some technical points are also detailed in the paper. Through the research, it demonstrates the potential and possibility of implementing BIM methods and techniques, particularly IFCs to enhance the computer applications in the processes of building construction and facility management.展开更多

The building forms, the distance between the buildings, the setback and the building heights would all affect visibility and were considered closely. Although this research methodology could be applied to any site in different situations, it remains simple and interesting. It can be applied in general, with a change of the variables （setback, distance between buildings, building height, building form）, to any site by both professionals and students who can simply use any CAD program for producing drawing in both the architectural or urban designs phases, hence the importance of this research. Two different building arrangements were proposed and studied： a linear and an L-shaped arrangement. After applying the simulations, it appears that the L-shape offers more visibility to the open space. The outcomes of this study were combined with another research project that studies the same building arrangements to test the possible climatic comfort provided in outdoor spaces in order to encourage the use of open spaces and walkability in the studied area.展开更多

If CAD technology is first innovation of information technology in construction industry, then the emergence of the BIM technology shall fully deserved to be treated as a second innovation in construction industry. As a new technology which have been introduced to China in recent years, BIM technology already had its major application in foreigner countries .This paper focuses on the current status of BIM technology application in our country, especially on some small and medium enterprises using the traditional BIM technology to handle the project which have complex usage,creative deign and cost limitation. Firstly,we take a deep analysis on the initial application situation. Then we go through the practical application and analyse what benefit can be given to a project from BIM technology.
