From daily life to the development of all walks of life, "risks" will be reflected. When it comes to risks, most people think of financial markets, but the construction industry is also closely related. Compared with investors, there are two important problems: whether the benefits of the project match the risks they face, and what is the maximum loss under unfavorable circumstances. The personnel in the construction industry come from two aspects: the entrusting party decides the project construction, while the entrusted party undertakes various specific tasks, such as building houses, roads, large-scale development companies or private owners. The entrusted party includes various professionals, such as architects, engineers, general contractors, various professional subcontractors and suppliers. The organizational composition of participants, the scale and complexity of construction projects will have different impacts on risks. Due to the large investment and long construction period of construction projects, there are many unforeseen factors in the construction process, such as changes in personnel, materials and equipment, and problems in investment decision-making, design, construction and use all affect the implementation of construction projects. Furthermore, the project risk will increase due to various factors. If we don't take precautions, it will probably affect the construction and even cause serious consequences. Therefore, the risk management of engineering projects is very important.
