Abstract
Modular container buildings, as new modular steel structure buildings with the advantages of modular construction and transportation, fast construction speed, and conformance to the concept of sustainable development, have achieved rapid development in the field of civil engineering in recent years. However, in view of the incompatibility of the standards and systems between the traditional construction industry and the container manufacturing industry, contradictions between industrialization, standardization requirements and diversified demands of buildings, and the low integration of the design system of modular steel structure buildings, the further development of the modular container building industry has encountered a bottleneck. In this study, for resolving this problem, it was proposed to coordinate the modular sequence of the construction and container manufacturing, establish a modular system for modular steel structure buildings, establish a database of container building components and parts, and integrate BIM and PDM platforms, to strengthen professional coordination and improve the integrated design that can increase the integration of the whole process of design. The application and verification in pilot projects such as Huaduhui Commercial Street have approved that this design method can effectively improve the standardization, industrialization, and information levels of design, production, and construction, increase the diversity and overall quality of modular buildings, and promote the achievement of the integration target of the modular steel structure building system.
Highlights
Modular container buildings, as new modular steel structure buildings, have not been applied in civil engineering for a long time, and they have been used to civil buildings on a large scale for only more than ten years
In order to ensure quality, improve efficiency, and save cost, we used partial standard parts of container manufacturing enterprises in the architectural design of the projects, such as Huaduhui Tourist Service Center, and firstly established a highprecision standard component model library for coordinating the relevant standards in the construction industry and manufacturing industry based on modulus coordination; we installed SECR software on the computer for mechanical manufacturing design and that for architectural design equipped with building information modeling (BIM) software, and connected them with the server, to realize the compatibility between product data management (PDM) data and BIM data [15]
It was proposed to establish a modulus system for modular container buildings and a database of components and parts of modular steel structure buildings, to strengthen professional coordination based on BIM and PDM platforms and improve the integrated design method for modular container buildings
Summary
As new modular steel structure buildings, have not been applied in civil engineering for a long time, and they have been used to civil buildings on a large scale for only more than ten years. There is a dilemma in the development of modular steel structure buildings at present: on the one hand, the industrialized mass production of modular steel structure buildings mainly depends on container manufacturers, and the facilities are primarily limited to low-end dormitories and stores consisting of a large number of repeated and straightforward units; on the other hand, as for modular steel structure buildings with higher quality requirements, there are construction companies involved in the design and construction, the inconsistency of the standards with the container enterprises, the low system integration, and unfavorable transdisciplinary coordination have resulted in several problems such as common design integration, redundant types of modules and components, low production efficiency, and high cost, which have severely restricted the development of the industry of container buildings For resolving such a problem, in this paper, the author coordinated the related modulus and size restrictions in the traditional construction industry, container manufacturing industry, and logistics industry based on the BIM platform and pilot projects and the advantages of BIM informatization, and proposed a unified modular sequence and three-dimensional modular grid for modular container buildings. To realize the integration of different professional software and the mutual access between databases, all the professional data, system software, and application software must adopt the uniform model data expression and information exchange standards in the BIM system [14]
