At present, smart construction sites in China are supported by software and hardware technologies, with integrated management platforms and data sharing centers as carriers, aiming to achieve the ten key management goals of schedules, cost, safety, quality, personnel, materials, equipment, techniques, environment, and informatization. Additionally, smart decision-making systems are also used to assist managers in making decisions and improving management efficiency. Although there are multiple successful cases for smart construction sites to learn from, there are still some problems. By summarizing the current development status of intelligent construction sites in domestic construction projects and studying relevant standards, the present paper analyzes the current development status of intelligent construction sites. Base on a project in Lanzhou City, Gansu Province, and drawing on the experiences of some engineering application cases, it discusses the problems in policy support, standards, technologies, talents and other aspects that impede the development of smart construction sites. Finaly, some measures and suggestions are given to address the issues raised, hereby providing a reference for the high-quality development of smart construction sites in construction projects.
