The invention relates to a digital construction management method based on public location service, including public location service platforms, wherein the public location service platform adopts a cloud platform, the public location service platform uses all-weather positioning scenes of outdoor, indoor and construction operation surfaces to realize positioning data storage and real-time positioning information issuance. The public location service platform comprises a GNSS/RTK/RTD/ZigBee/WiFi/BLE positioning technology and a positioning terminal. Based on different management requirements and objectives, the positioning terminal is associated with corresponding personnel, equipment or materials, and can dynamically track real-time position and historical running trajectory information,and is released to upper application systems through an interface. The invention realizes the combined positioning of the human resource machine and the fusion of the human resource machine and various professional directions by establishing a public location service platform, and realizes the comprehensive, service multi-objective digital construction management and meets the requirements of engineering quality, safety, resource management and performance evaluation.
