With the upgrading of building industry, intelligent construction and intelligent operation and maintenance, it has been a trend to deepen the application of BIM technology in construction projects. Taking the large-scale industrial park project as the research object, this paper gets rid of the difficulty of positioning and integrating the group project model by using the method of shared coordinates in BIM software. In the aspect of deepening mechanical and electrical pipelines, the visual programming software Dynamo plug-in is used to realize the color filling of different beam heights with one-key operation according to the complex characteristics of basement elevation changes. What's more, the clearance under the beam is intelligently analyzed, so as to provide a basis for the comprehensive layout of electromechanical pipelines. The research results can provide reference for similar projects.

BIM model data is an important component of urban data assets, and reasonable construction of BIM model quality evaluation system is an important guarantee of BIM model data quality. This paper takes BIM models in the scheme design stage of Xiongan New Area in many professional fields, e.g. architecture, road traffic, municipal pipeline and utility tunnel, as the main evaluation object, and discusses the characteristics and applicability of computer automatic judgment and manual judgment. The paper further discusses BIM model quality evaluation index system centering on six dimensions, i.e. model integrity, model normalization, model correctness, model attribute consistency, model collision and spatial consistency. Finally, the method proposed in the paper is successfully implemented and verified in the model quality inspection of Xiongan New Area.

BIM technology, known as the second revolution in the construction industry, has created a wave of research and application all over the world, and its application in structural design in China has become more and more extensive. The seismic reduction and isolation structure are slightly different from the conventional seismic structure. This article takes a high-rise RC shear wall foundation combined seismic isolation structure in a high-intensity area as an example, uses BIM technology to build an overall structural model using Revit software. Firstly, creating a structural model of each part and a family of seismic isolation devices through software parameterization; then using a detailed list to calculate the mechanical parameters of the selected seismic isolation devices, and then using the explosion analysis diagram to visualize the composition and relationship of the seismic isolation structure. Finally, through the two-way link of Revit and Robot and YJK three softwares to try to share model information and explore the application of BIM technology in high-rise seismic isolation structures.

The shock absorption and isolation structure structures are different from traditional seismic structures, the pain point of building BIM models in current structures mainly lies in the seismic isolation and energy dissipation device. This paper uses BIM technology and Revit software to build the energy dissipation device family to fill the gap that the Revit system the third party library have no energy dissipation device family components; by parameterizing the family components of seismic isolation and energy dissipation devices, it can achieves the creation of different family components; the product parameters of the created seismic reduction and isolation energy consumption device are counted through the detailed list. Finally, to load the constructed family into the structural model, and to explore the application of BIM technology in shock absorption and isolation structure.
