The construction industry is a kind of multi-project engineering. The management in the construction process is an important factor in ensuring construction quality. This paper briefly introduced the relevant content of building information modeling (BIM) and the application of BIM combined with the genetic algorithm in optimizing the processing scheme in the cutting process of steel structure buildings, and took a grid-shaped steel shed in Zhengzhou, Henan, as an example to compare the traditional and BIM optimized schemes. The results showed that the BIM-optimized scheme could make better use of raw materials with different specifications and the optimization scheme had higher economic benefits because of higher utilization rate, fewer processing personnel, and fewer working hours

The quality management is an important indicator that affects building projects value and practicability on peoples’ work and life. When building quality cannot reach the standards, it would bring personal safety and property into danger. BIM-based technology has been proved that it can effectively provide specific solutions to deal with quality issues and improve quality management efficiency in the entire project life cycle. It is a significant technology to upgrade the traditional construction industry into automation and intelligence through stimulating specific construction works into a visual reality. Therefore, quality management efficiency can be enhanced on labour, material and equipment sources through BIM-based system. This paper would analyse how BIM-based quality management methods can improve the efficiency and accuracy of building project quality issues.

A smart, sustainable city that employs ICTs (information and communication technologies) improves urban businesses and services’ quality of life, productivity, and competitiveness. A sustainable smart city’s significant challenges are legislation and regulations, financing, technical and infrastructural dimensions. While at the same time providing for the economic, social, environmentally, and cultural needs of the present and future generations. Continuous population and urban development have stepped up creative ways of tackling urbanization, with limited implications supporting smart cities’ environments. This cram aimed to build a user-centred design using a sustainable big data analytics assisted optimization framework (SBDAAO) to step up creative ways of tackling urbanization with limited environmental implications. This research represents a first move to provide perspectives and value in creating intelligent cities to instil sustainability. Simulation analysis has been carried out based on the data collected based on city infrastructure. The experimental results have been executed, and the suggested method achieves an accuracy ratio (98.2%), the efficiency ratio (95.5%), energy consumption (20.1%), average communication delay (17.6%), and renewable power (93.9 %).

Green building is the inevitable trend of the development of the construction industry. One of the key links to realize green building is green construction management. The poor economy of traditional construction hinders the smooth promotion of green construction in the construction industry. This paper mainly from the green building and green construction two concepts of related content research. Through the analysis and discussion of the main principles of project cost management in green construction, this paper briefly expounds some implementation measures of project cost management in green construction. This paper deeply discusses the current situation of green construction project cost management, and puts forward relevant improvement countermeasures. The experimental results show that: construction enterprises should make innovative thinking on construction management and bring green construction into project management. This can provide impetus for the sustainable development of the construction industry.

Design plays a leading role in architectural design, which determines the quality of construction projects. At present, most of the prefabricated constructures are designed according to the principle of cast-in-place construction, and the structural system basically follows the mode of cast-in-place structure. The advantages of prefabricated industrialization have not been reflected in the system of prefabricated construction structure and design. Due to various factors, it has become highly difficult to design prefabricated buildings, making it impossible to complete the design with the help of traditional design tools. Instead, it needs to rely on BIM Technology to complete the prefabricated construction design so as to make the construction projects visible, controllable and informationalized. Moreover, the design information from various parties concerned can be highly integrated and coordinated, thereby improving the efficiency and quality of construction projects and enhancing buildings' quality [1].
