Abstract:
As a new idea and technology, BIM has been looked as the second design revelation. While the pushing to apply BIM in the design institutes is required. This paper looked back the important actions of the Chinese design institutes in the "Throwing off Drawing Board" project, analysed the significance of BIM to raise the competition in the building markets for the design institutes, expounded the leading role and function of the design institutes in the BIM applications, displayed the excellent performance of the design institutes who are walking in the forefront. The above key points indicate that the Chinese design institutes will still play an important role in the BIM wave. Based on the analysis of the problems in the BIM application in the Chinese design institutes, this paper give some suggestions on how can governments, professional experts, designers and software developers can push forward the BIM applications.

Abstract:
Owner, architecture/engineering firm and constructor are three main players in BIM adoption. There are different key issues for different type enterprises during different stages. The paper provides following views after analyzing current BIM adoption situation in China. The key issue for owner is to build its' own team's BIM capability, A/E firm is to manage right BIM uses and investment size, and constructor is to standardize and popularize mature BIM uses.

Abstract:
On the background of a mountainous area highway cut slope engineering, a plane strain finite element model is built by PLAXIS with its embedded strength reduction method for stability analysis.Firstly, the slope stability under excavation and reinforcement is analyzed according to the exposed stratigraphic, indicating that global stability requirement will be satisfied with frame anchor reinforcing the first two stage slopes. Secondly, after some studies it can be seen that overlying weathering layer thickness which significantly affects slope stability, a major research object for optimized design. Finally, the effect of the strength parameter c、φ, of strongly weathered layer and moderately weathered layer, on the slope stability is calculated using the built-in parameter sensitivity function of PLAXIS, which shows that c value of the strongly weathered layer has the most apparent influence on the result.

Abstract:
In recent years, BIM technology develops rapidly in the construction industry.As the representative software of the application of BIM technology, Revit can realize collaborative design of architecture, structure, construction, and MEP, and has been widely used in building design field. However, Revit does not meet the building code well in our country currently, so the structure analysis become a lonely island in the entire three-dimensional model information chain, resulting in a large number of domestic structural model can't apply collaborative design in last decade. PKPM structural analysis software combines closely with Chinese building code, and it is widely used. Therefore, it is of great significance to develop a bi-directional data interface software between PKPM and Revit. This article develops a bi-directional data interface software between PKPM and Revit on the Revit platform, and discusses several key issues in the software, along with the detailed solutions.
