Abstract
The construction industry is a labor-intensive industry in China. Due to the unsaturation of pore gas, the unsaturation of soil mechanical properties is more complicated than saturation. Changes in water and gas will cause changes in soil attractiveness, which will further affect the mechanical properties and permeability of the soil, and even threaten the stability of the slope. Therefore, in order to study such engineering problems, it is necessary to comprehensively and correctly understand the changes of unsaturated soils during the drying and wetting cycles, and to investigate the reasons for the changes in order to scientifically analyze the stress state of unsaturated soils. Because of the continuous advancement of technology, people’s comfort requirements for the function, appearance, and structure of buildings are also constantly improving. Especially in some modern large-scale construction projects, due to the large number of contractors, the amount of information that needs to be analyzed in the construction process is compared. The requirements for large and project engineering management are getting higher and higher, which makes the difficulty of the project greatly increased. Relying on traditional information communication and management methods, project cost management becomes difficult. Project cost management is one of the core contents of project management, and its management effect directly affects the final value of the project. On the basis of the continuous improvement of management ideas and theories in manufacturing management activities, project cost management introduces BIM technology currently active in the construction industry. Based on the characteristics of BIM core technology and BIM model software, it carries out in-depth research, explores the connection between BIM Technology and project cost management, and constructs the fine management mode of project cost.
