Abstract:
Modern technologic progress and increasingly fierce market competition have stimulated the owner, designer and contractor to initiate a new technological revolution of BIM and 3D printing in the building industry. BIM application plays a more and more important role in the building′s design and construction with the effects of cost reduction, quality improvement and construction period shortening, especially for the complex large-scale projects. There are some difficulties in conducting the project of Urumchi International Highway-railway Combined Passenger Station, such as the short construction period and the great variety of precision prefabricated components. Therefore, our BIM team started using BIM at the early design stage and then continued to the production and construction phases, achieving an efficient management working pattern. This paper firstly focuses on the technical measures, workflow and coordination mechanism established during the starting phase of the project. Following that, it introduces the means of realizing the targets, solving the problems and increasing the accuracy. Finally, the application effects of BIM are concluded and analyzed while some optimization measures are suggested in the future.

Abstract:
With the rapid growth of economy and the progress of science and technology, modern information technology has been widely used in industrial production as well as daily life. The projects of super high-rise buildings involve large investment, long period of construction, participation of numerous contractors and complexity in construction management. In the principal contract management, the traditional way of information communication and management couldn′t meet the requirements. As principal contractor, we adopted the BIM methodology to help us to manage the complexity. This paper takes the project of South Tower, Pingan International Finance Center as case study. It describes the initial phase of the BIM organization and planning, the construction of the BIM application environment and the application of BIM technology in the high-rise construction management. It demonstrates how the management challenges were met through the integration of design and construction with BIM based solutions.

Abstract:
Building Information Modeling (BIM) is the second technology revolution of the application of information technology, and it has become an inevitable trend in the informatization of construction industry and high-efficiency application management. Urban rail transit involves various professions, and the communication and coordination between these professions could be difficult. In this paper, management based on spatial visualization using BIM was applied in domain of urban rail transit development. The application of BIM started from five stages, which were preparation of project, modeling for different stages and professions, model integration, application in construction, and collection of feedback information in the late period. BIM technology was used in the basic applications such as three-dimensional instruction, construction simulation, construction application, guarantee of progress, control of cost, supportive management of safety and quality and so on. Furthermore, it was exploited in applications such as analysis of energy conservation, assistance in modification of pipeline and simulation of emergency evacuation. Based on the mentioned applications, BIM technology was utilized throughout the subway construction period. BIM technology helps to achieve the informatization management of subway construction project and creates construction sites with intelligence and civilization.

Abstract:
In recent years, with the owners of bridge landscape design requirements increasing, a variety of bridge curve shapes have emerged as the times require, most of which are steel structure bridges. It is quite difficult to show the design intention of 2D drawings with a conventional structure with space curve shape. Although design only takes up 70% of the total cost of the whole building life cycle, it decides 5% of its total cost. If uses the BIM technology with a high degree of visual data, high integration and good coordination in design stage, could completely show the intention of the design institutes, improve the machining precision of steel plate, improve the construction organization, reduce construction waste, but also provide accurate and reliable model for the implementation of BIM technology of a late bridge pipe carrier. At present, the complex steel structure bridge direction starts from real application of BIM technology design is still blank. BIM does not have the characteristics of mold design, is truly the first step the whole life cycle of BIM application from the beginning of design take the key.

Abstract:
Wind load was often the key load for the safety and comfort of super-tall building structures.Large eddy simulation(LES)technique combined with a new inflow turbulence generator(NSRFG)was employed to study the wind effects on tapered building models with different tapers, which aimed to compare the effect of different taper on wind loads and wind-induced responses of the structure and validate the applicability of the numerical method of this paper.Numerical simulation showed thatthe distributions of the average and fluctuating pressure on building surfaces were similar, whilefor the wind-induced response, the peak base bending moment(BBM)of different models in across wind direction decreased remarkably with the increasing of the taper.Therefore, a building with bottom-up gradually shrinking and an appropriated tapershape can effectively decrease the aerodynamic wind load in across-wind direction.In addition, results from the numerical simulation were coincided with that from the wind tunnel test in the whole, which indicated that LES technique combined with an appropriated inflow turbulence generator would havecertain accuracy and canprovide valuable reference to the aerodynamic shape optimization of super-tall buildings.
