Abstract:
With the adjustment of national policies and the establishment of the goal of building industrialization in 2035, intelligent construction site has gradually become the mainstream trend of construction methods in the future. Intelligent construction site has the characteristics of digitization, networking and intelligence. In such a working environment, the corresponding command and management work also needs to be upgraded accordingly. In this paper, a mobile folding dispatching room for intelligent construction site is designed. With the goal of efficient and fast work, it is designed from three aspects: mobile folding, equipment system, and system function, forming a set of work system with fast positioning, complete equipment system and complete functions. It provides a certain reference significance for the command of intelligent construction site.

Abstract:
At present, the research on the integration of BIM and GIS is mainly divided into three directions, namely data format conversion, data standard extension, and ontology. This project chooses to carry out the entity integration of IFC and CityGML through the ontology mode. The triples of entities are extracted through semantic modification, and then the triples are represented as entity vectors by knowledge representation learning. The semantic information of entities is transformed into a low-dimensional vector space, and the matching fusion system of IFC and CityGML standards is constructed based on extended semantic matching. To solve the problem of semantic understanding bias of the same entity under IFC and CityGML, and to cluster by similarity calculation. In addition, the extracted triples were used to carry out geometric reconstruction using entity-relations-entity, and the entities of IFC standard were mapped to entities of CityGML standard. Finally, the established 3D model is used to verify and to realize the transformation from BIM field to GIS field.

Abstract:
With the advent of digital economy, digital transformation has become a hot issue in the international construction industry. Using the core database of "Web of Science" as the data source, 181 papers published between 2010 and 2020 were analyzed for their spatial and temporal distribution, knowledge base, research hotspots and development trend, and the development of digital technology in the international construction industry was sorted out. The research results show that: although the international research output on digitization in the construction industry is increasing year by year, there is still more room for progress in the degree of cooperation among authors, research institutions and countries; the current research on digitization technology in the construction industry mainly focuses on BIM technology, and other new digitization technologies are also gradually gaining the attention of scholars; the research hotspots include not only the digitization technology itself, but also the the research hotspots include not only the digital technology itself, but also the specific application stage and application value of digital technology; the research frontiers include digitalization, digital transformation, user adoption, etc. It is predicted that the future research on digital technology in the construction industry will show a cyclic development trend of "development of digital technology-adoption and application of digital technology-challenges in the application process-corresponding solutions". The research results aim to provide reference for the development of digital technology in the domestic construction industry and promote the digital transformation of the construction industry in China gradually.

Abstract:
Assembly building has been vigorously promoted due to its convenient construction and green environmental protection. As a key link in the construction process of prefabricated construction, hoisting operation involves many safety management elements and complex relationships. The current hoisting safety risk management methods still have problems such as low intelligence level, unguaranteed prediction accuracy, and unreal-time control of safety management factors. In view of the above hoisting safety risk management problems, this paper introduces the concept of digital twin into the field of hoisting safety risk management, analyzes the inducing factors of hoisting safety risk, builds a digital twin framework for hoisting safety management, and expounds the operation mechanism of digital twin model. And based on the key problem of digital twin modeling, the modeling methods of physical hoisting process, virtual hoisting process and virtual and real information interaction are proposed, which have been put into practice in a project to verify the effectiveness of the method, providing theoretical support and technical support for the application of digital twin in hoisting safety risk management.

Abstract:
At present, the understanding of shield construction conditions is mainly based on the data returned by shield machine sensors. However, the variety of shield parameters and the large amount of data make it difficult to directly obtain valuable information from them, especially for super large diameter shields. This paper proposes a method for constructing a Partial Correlation Threshold Network (Partial Correlation Threshold Network, PCTN) based on the tunneling parameters of a super large diameter shield, and introduces the commonly used indicators for quantitative analysis of network topology. Finally, based on the measured data of a super large-diameter cross-river shield tunnel project, a shield parameter network diagram is drawn. By obtaining the macro index of the shield parameter network and the statistical index of the shield parameter itself, the relationship with the excavation surface pressure is analyzed. Correlation of fluctuations. This article provides help for more in-depth exploration of the interaction mechanism between parameters, and the prediction of the stability of the excavation face.

BIM-based construction drawing checking system, the system checks whether the imported BIM 3D model meets the key domains, semantic rules, and data standards, which are established by analysing related specifications. By predicting architectural design errors, associating problematic components, and providing visual positioning, this process avoids manual tedious and repetitive work that can effectively improve the efficiencies. The model will be loaded into the CIM(City Information Modeling)platform once it passes the checking.

Abstract:
As one of the modern transportation infrastructures, the demand of expressway construction keeps growing since China is now standing at a historical juncture of achieving the two centenaries′ goals. The ratio of tunnel in expressway construction is much higher in Yunnan province due to mountainous topography; traditional design method cannot satisfy the demands nowadays, therefore, BIM technology is introduced since it becomes a main direction in project design. Since tunnel in expressway looks like a flat ribbon geometrically, goes up and down spatially, presents cross-section differently, if architectural BIM method is directly applied, it actually doesn't work and doesn't acclimatize. "Revit+Dynamo" method is used in this article to solve the real 3D modeling of long spiral tunnel, which accumulates experience for future tunnel BIM modeling practice.

Abstract:
In recent years, with the continuous deepening of the digital economy in China and the development of digital applications due to COVID-19 situation, digital transformation has been raised to the top priority for enterprise survival and development. But many enterprises, specifically those engineering design companies whose information level is weak, cannot clearly understand what digital transformation is, how change can be made, and what the relationship between the digital transformation and information digitalization is. Based on the above concerning, the author hopes to help readers return to the essence, to clarify thoughts, to understand the underlying logic and value demand of the digital transformation, and to explore the road of digital transformation of engineering design enterprises with the concept of "long-termism, value symbiosis".

Firstly, the development status of automatic compliance review system is introduced, and then the key technologies of automatic review of fire design, namely the information extraction technology of fire protection standards and specifications and fire design information extraction technology based on BIM model are summarized. Finally, the specific method selection principles and ideas of key technologies are discussed, and it is suggested to strengthen the top design of BIM related specifications.
