The inland waterway regulation works have the characteristics of long lines as well as multiple areas and concealed works，and they are exposed to problems such as difficulties in construction quality tracing and process control and low efficiency of construction management. In view of the key difficulties in the construction of inland waterway engineering，we realize the in-depth creation of building information modeling （BIM）and integrated application of the multi-source model by using corresponding intelligent construction equipment. Relying on the waterway regulation project of the Yangtze River Estuary of the Beijing-Hangzhou Grand Canal，the modeling and integrated application are based on the BIM technology and intelligent construction site management platform. In addition，we have solved typical problems such as mass concrete pouring，long-line construction process control，process inspection of complex concealed works，as well as construction and monitoring data management，realized the integration of the BIM technology and management platform in the construction stage，and improved the construction quality and technical management level of engineering construction projects.
