With the expansion of the scale and complexity of construction projects, the safety managementof construction sites is facing severe challenges, and construction enterprises urgently need to change thetraditional safety management methods. With its advantages of transparency, refinement and digitization,grid management is widely used in community governance and other fields, but there is still littleapplication research in the field of construction. Therefore, grid management is introduced into the safetymanagement of construction projects, and the safety grid management system is improved from the aspectsof personnel system, optimization of equipment control mechanism and construction of intelligentinformation platform. Combined with practical cases, the advantages of the system in improving the levelof construction safety management and significantly reducing the accident rate are demonstrated.
