To the problems of high safety risk coefficient，high personnel control requirements，high installation difficulty，and tight schedule in the construction of LNG (liquefied natural gas) terminal engineering，research and application based on BIM and Internet of things technology on the intelligent construction site platform have been carried out.By adopting the intelligent site management method that integrates BIM technology and internet of things technology，we deepen the creation of construction BIM model，and combine the corresponding intelligent equipment to realize the application of model and on-site data access and integration，which solves the problems in the construction process of typical LNG terminal projects，such as difficult control during construction，multiple data information sources integration，and difficult on-site management of labor personnel.By integrating BIM technology with intelligent construction platforms during the construction phase，the construction quality and technical management level of LNG terminal construction projects have been effectively improved.The significance of this study lies to provide useful experience and reference for the construction of LNG terminals，and promote the application and development of intelligent construction site platforms in this field.
