Abstract: This paper introduces the role and implementation path of digital construction in the development of new construction industrialization. An example of prefabricated construction project is given for showing some digital construction techniques and its effects, though adopting digital construction technology, the project construction period is shortened by 25%, the total cost is reduced about 5%,which effectively improves the comprehensive benefits of the project.The essence and basic of intelligent construction and smart construction are digital construction.The coordinated development of intelligent construction and the new construction industrialization must pay more attention to digital construction.The most important direction to promote the development of digital construction is to establish a whole process,full-professional and multi-party information management standard and system based on BIM top-down design.
