Abstract:
In recent years, the BIM technology is under promotion in domestic construction industry of China, with many construction enterprises and architectural design enterprises formulated their own enterprise-level BIM technology development plans. All these plans will inevitably involve BIM demonstration projects. The authors of this paper has participated in the management of five batches of BIM demonstration projects in CSCEC in the past five years. In this paper, experiences are summed up concerning all the processes of BIM demonstration projects in construction enterprises including top-level planning, project declaration, process control, and acceptance and promotion. This paper also answers some questions like how should the management department of BIM demonstration projects guide BIM demonstration projects to apply BIM technology, as well as how to improve BIM application by promoting these demonstration projects. All these experiences can provide references for related enterprises that are carrying out BIM demonstration project management.

Abstract:
Using BIM in construction projects can achieve huge benefits. In recent years, the facilitation of BIM has been widely improved in various countries. At present, BIM is mainly used in the design and construction phase of China's railway projects, and this does not reflect the true value of BIM. This paper discusses the characteristics of operation-oriented applications in BIM-based railway projects, and also studies the operation-oriented applications include an organization mode that lead by operation department and BIM consultation team; an operation-oriented hybrid system that involves multi-platform and various linked systems; and a collaborative workspace named IROOM. By comparing the conventional BIM applications, the operation-oriented application proposed in this paper considers the needs of lifecycle management on railway projects. It uses an operation-oriented method to regulate the design and construction phases, this in turns promote the use of BIM in railway projects. This paper provides a useful reference on the information integration in BIM-based railway projects.

Abstract:
This paper illustrates the reinforcement and transformation process of a concrete frame structured machine house based on BIM technology. A BIM model is established by using Revit based on the current situation of existing buildings to realize the 3D visualization and collaborative work. The optimization of building renovation plans was achieved from the aspects of pipeline optimization, collision detection (such as collision of column with pipeline and window, collision of beam with pipeline, etc.) and so on. The sunshine analysis function in Revit is helpful to rationally arrange the room, partition material, and etc. The application of BIM technology in the reinforcement of the existing building will avoid changes encountered in the traditional reinforcement and reconstruction.

Abstract:
Quantitative statistics is one of the most valuable application of BIM technology of great significance. Considering that the reinforcement engineering itself is incomplex and changeable structure, involving many relative atlases and codes, as well as all different kinds and parameters, the Revit software is functional limited in the graphical display of reinforcement engineering, leading to the lack of development and solution of BIM reinforcement calculation. In response to the above problems, based on the secondary development on Revit, this paper realizes 3D reinforcement quantitative statistics to provide scientific and accurate data support for the statistics of reinforcement materials, which has broken through the technical bottleneck, and deeply excavated the application value of BIM in reinforcement engineering.

Abstract:
There have been many policy documents in state-, province- and city-levels about the development of prefabricated buildings in recent years, which are aiming at promoting the application of prefabricated buildings. Currently, the prefabricated buildings can be built by two forms of fully prefabrication and partial prefabrication, in which the latter one is of more applications in the industry. This paper introduces the construction progress of a certain partial prefabricated building project, and sorts out the problems related to the construction of partial prefabricated building. Relevant opinions and suggests are promoted that, in the design stage, the overall planning of PC component application deserves more attention to be paid, and that effective transformation of design drawings should be noticed in the implementation stage to connect the design, production and construction processes. Only by strictly controlling the quality of PC components, can the superiority of assembly building technology be brought into full play.

Abstract:
As a newly emerged technology, the BIM technology still possesses many uncertain factors or uncertain trends in the future. Under the background of BIM application in the whole industry, it is generally believed in the whole industry that BIM technology can bring higher economic value, which, however, lacks of strong support of evaluation system. Based on the characteristics of BIM technology, this paper determines the performance evaluation index through integrated methods of questionnaire survey and literature induction, and also establishes a performance evaluation system of engineering projects of BIM technology by using the analytic hierarchy process and fuzzy comprehensive evaluation. The established BIM project performance evaluation system is then applied in a BIM pilot project which has completed acceptance to conclude comprehensive evaluations of the performance of the project.

Abstract:
With the continuous development and popularization of BIM technology, increasing numbers of engineering projects are willing to use BIM technology. Traditional design and construction management mode using CAD, which focuses on the engineering drawings, is no longer able to meet the requirements of highly complex construction engineering. For an enterprise in the industry, BIM applications should not only limited with the establishment and application of a 3D model. There is an urgent need for a BIM system platform to manage and control all engineering projects, to achieve scientific decision-making, to accumulate construction experiences, and to support later operation and maintenance management.

Abstract:
With the increase of traffic pressure in China, the subway has become the main mode of travel to relieve traffic pressure. At present, the construction of the subway has entered a peak period, but the quality problems of the tunnel has also come one after another. The shield method has already dominated the tunnel construction methods. In the shield tunneling, the quality of the entire life cycle of the segment directly determines the quality of the entire tunnel project. At present, the segment detection technology adopts the method of manual work, there are problems such as slow information processing and information sharing troubles. How to use information technology to realize integrated management of detection information has become a trend. Firstly, this article analyzes the inspection information at each stage of the segment. Then, based on the IFC standard model system, expansion methods and graphic representation methods, the segment detection information was expressed and extended, and a segment detection information model based on the IFC standard was established.

Abstract:
To investigate the seismic behavior of innovative precast self-insulation reinforced concrete shear walls under different axial compression ratios, the authors conducted reversed cyclic loading test through designing and manufacturing 4 groups of 12 RC shear wall specimens, which are all ingle-shaped shear walls with the same reinforcement, and with hidden columns at both ends. All specimens include one group of solid cast-in-situ shear wall specimens for contrast, one group of post-filled hollow precast shear wall specimens, and two group of innovative precast self-insulation precast RC shear wall specimens. A refined finite element analysis model of self-insulating concrete shear wall is established by using ABAQUS finite element software. Results indicate that the self-insulation precast shear walls perform equally well in averaged yielding load and peak load in comparison with the precast solid shear walls under the three design axial compression ratios. While the ductility ratios and accumulated dissipated energy of precast self-insulation shear walls are lower than those of precast solid shear walls, the stiffness degradation curves of the two kinds of shear walls are smilar with each other. When the horizontal displacement at the top of shear walls is within ±20 mm, the energy dissipation ratios of the two kinds of shear walls are similar under the three designed axial compression ratios, but when the horizontal displacement is over ±20 mm, the energy dissipation ratio of the precast self-insulation shear walls will be somehow higher than that of solid shear walls. The error between the numerical simulation results and the test results of the peak load test of the self-insulation precast shear wall specimens are within 5%, which satisfies the engineering accuracy.

Abstract:
The scheme design is the very initial stage of the architectural design, which acts as a key role in achieving the expected comprehensive objectives of the project. For the green buildings, the scheme design will focus more on the environmental performance, considering many design factors. So, the task is a typical multi-objective and multi-attribute decision-making job. Based on the parametric design theory, this paper analyzes and extracts the key design factors affecting environmental performance during the scheme design phase, and then establishes a design optimization model with energy consumption and natural daylight as the objective functions. Through integrating the NSGA-Ⅱ algorithm and GBS simulation by using Dynamo, the model can be solved, and the optimal design scheme will be selected. Lastly, a case study is conducted to verify the validity.

Abstract:
With its unique advantages, construction informatization is increasingly recognized by the whole industry of engineering and construction. However, compared with the previous 2D design, Revit still has some problems such as inefficiency when its BIM model is applied in engineering design for adjusting pipeline gradient. Referring to the Outdoor Drainage Design Code (GB 50014-2006) Gradient, this paper studies the BIM-based gradient adjustment water supply pipeline through the application of secondary development on Revit.Through the secondary development technology, the corresponding relationship between pipe diameter and slope value is adjusted in batches, which makes the Revit software more efficient and convenient in collaborative work, and meanwhile greatly reduces the error rate. Finally, an engineering example is presented, which provides a reference for promoting the development of BIM software and other technologies.

Abstract:
The ISO 19650 series is a new international standard for the management of information when using building information modelling (BIM). The new standards aims to enable teams to minimise wasteful activities and increase predictability around cost and time. Designed to be achieved through a common and collaborative approach to the management of information. This is especially beneficial at a time when we are increasingly seeing delivery teams formed of organizations from different countries, with different cultures and differing ways of working, coming together on projects. Many organization currently align to BS 1192 series of standards. Therefore, it is vital or those organizations to get the help and support needed to transition from the UK 1192 series. To assist adopting, a new publication (PD 19650-0) contains transitional guidance for those familiar with the UK 1192 series. Including the mapping of terminology and key amendments.
Moving forward, three leading bodies - British Standards Institution (BSI), UK BIM Alliance and the Centre for Digitally Built Britain (CDBB) agreed to collaborate to create a single guidance framework for the adoption and implementation of the ISO 19650 series.
