Abstract:
The BIM-based compliance checking of architectural design is of great significance to improve the standardization and accuracy of BIM forward design, as well as to ensure the reliability of BIM submission as design results. Through the introduction of the application of expert system in compliance checking, this paper analyzes the acquisition and expression of knowledge of architectural design codes, establishes the rule base of architectural design codes, and proposes the basic method of BIM information extraction and mapping. On such theory basis, the paper further proposes the basic framework of compliance checking system, and develops the prototype system of BIM-based architecture compliance checking system, whose theorization and feasibility are verified by practical cases. At last, considering the future development of the intelligent system for compliance checking, the paper puts forward some suggestions from two aspects of model delivery standards and specification definition.

Abstract:
Due to the advantages of good integrity, strong applicability and reasonable stress, the cast-in-place continuous beam bridge has become one of the most widely adopted bridge types. Meanwhile, BIM technologies play increasingly important role in the value of infrastructure construction, but there are still many difficulties during the modeling process of cast-in-place continuous beam bridge. To solve those problems during the process of cast-in-place continuous beam bridge design modeling, such as the slow speed and the complex of upper structure, this research collected the data from circuit design line, created the Revit parametric components, prepared a list of the bridge Excel component parameters and provided Dynamo automatic modeling program, which in overall has presented a set of complete solution based on the pattern of "Revit+Dynamo" cast-in-place continuous beam bridge design modeling method. It enables to model the complex upper part of the structural components, as well as enable the rapid modeling process of bottom structural components. It has greatly improved the degree of refinement and has improved the efficiencies of modeling, also it has provided a more reliable basis for data extraction and data analysis of cast-in-place continuous beam bridge construction.

Abstract:
In view of the current problems of low efficiency and complex calculation existing in establishing tunnel excavation model by using Revit software, this paper innovates the modeling method on the basis of existing functions of the software, improving the modeling speed. The parameterized component family contributes to the reusable model, and the detailed list function contributes to the automatic operand, both resulting in better application of BIM technology in the tunnel excavation and construction. In that the structural beam possesses parametric cross sections, and can be drawn easily, it is used to create parametric beam family. The section parametric beam family is then applied in Revit to rapidly draw the tunnel excavation model by picking up axis command. Both the surface wall and surface roof families are applied to create models for multi-layer sprayed concrete, which provides convenience for the 4D construction simulation. The detailed lists of wall and vault are used for instant calculation of the concrete quantity for spray. The curtain panel family is used for the modeling of single anchor, making the model parameterized, which improves the modeling efficiency. The command of reinforcement mesh is applied to solve the difficulties in drawing reinforcement mesh of side wall. By changing the parameters of steel mesh, the size of steel mesh can be controlled, leading to easy obtaining the calculation quantity and better controllability of the model.

Abstract:
With the rapid development of domestic super high-rise buildings in China, both the scale and depth of deep foundation pit projects keep expanding, and more deep foundation pits appear in the areas with dense buildings and population, which puts forward higher requirements for the design and construction of foundation pit projects. However, the present 2D survey data are incomplete and inaccurate, which restricts the effective application of geotechnical survey data by all parties involved in the project. The BIM technology, with its own characteristics of 3D visualization and parameterization, is able to apply the information of abstract and complex survey data to construct a digital 3D model with given geological information data. Then, communication and decision-making according to the digital 3D geological BIM model will improve the scientificity of engineering design scheme and construction scheme. This paper takes the BIM application in the foundation pit and basement engineering of the Qianhai Trading Plaza Project an example, to elaborate the application process of BIM technology in complex geology and pile foundation engineering. The feasibility of BIM application is demonstrated by comparing and analyzing the real data of the project. The study is able to provide reference for the construction of similar complex geological foundation pit.

Abstract:
3D laser scanning technology can use high-speed laser to quickly obtain the three-dimensional coordinate data of the object surface. Through registration and filter of point cloud data, a point cloud model reflecting the actual construction effect can be further constructed. By comparing the point cloud model with the BIM design model, the dimensional and position deviations generated during the construction process will show up, which can further direct the subsequent construction process or design changes. Based on BIM technology and 3D laser scanning technology, this paper proposes a set of theoretical comparison methods between point cloud model and BIM model, and uses WebGL technology to realize the visualization of the comparison results.
