In order to solve the problems of difficulty in daily management of engineering materials and equipment and difficulty in collecting statistical data of materials and equipment, a method based on the combination of BIM (building information modeling) technology and Internet of Things technology is proposed to construct 3D model files, engineering quantity files, and construction schedule plans to determine BIM and Internet of Things technology methods in material management of construction projects. The method based on BIM technology and Internet of Things technology 5D material-integrated management platform can realize the daily management of materials more finely. For the construction industry, cost management is always an important factor related to the direct interests of design companies. The cost of building materials accounts for about 70% of the total project cost. The frequency of the tag is usually 2.4 GHz∼5.8 GHz, and its reading range can reach more than 100 m. This shows the importance of construction material management in construction projects. Taking BIM technology and Internet of Things technology as the starting point, this paper deeply analyzes the advantages of BIM technology and Internet of Things technology. It is verified that combining with the main points of material management of construction projects, from the perspective of practical application of technology, it focuses on the effectiveness of practical application of material management of construction projects.
