As one of the most advanced technologies in the construction fields, the BIM technology has created great values in the design, construction, operation and maintenance period, which is gaining its wider acceptation in the industry and companies. At present, the BIM application in the marketing stage of the real estate industry is still limited with some areas, and there is not a method of BIM application throughout the marketing stage. This paper comprehensively studies the various factors that affect the decision-making of the real estate buyer, and analyzes the advantages of BIM application of visualization, coordination, simulation and optimization in the real estate industry. Considering the many application areas of BIM technology, a complete set of application methods of BIM is summarized and created. To consider problems from the prospect of real estate buyers, and to exhibit the top concerned issues of the real estate buyers in the purchase process through the visualized BIM model, the complete application method of BIM technology in the residential real estate marketing is finally formed, promoting the marketing management to the strategic height of enterprise development, and looking forward to the whole process of marketing from the perspective of studying the needs of consumers.

In recent years, with the development of information technology in the construction industry, BIM technology has emerged. It provides favorable conditions for civil defense engineering construction. This article introduces the concept of BIM and mainly studies the application of BIM technology in design and construction of civil defense engineering. The author analyzes and summarizes the key application of BIM technology in civil defense engineering by participating in design and construction of a civil defense engineering.

Compared with the virtual reality (VR) technology and augmented reality (AR) technology, the mixed reality (MR) technology owns the advantages of flexibility, interactivity and real-time performance. Therefore, the MR technology has gradually become an important way to realize intelligence and informationization in different industries. The application of building information model (BIM) technology has promoted the informatization of the construction industry, while the combination of MR + BIM becomes a new research direction in our construction industry. Through using the Hololens developed by Microsoft, this paper explores the application of BIM technology in construction, which is able to enhance the visualization, real-time and high-efficiency construction industry, which provide new ideas and new methods for building engineering intelligent and informatization.
