With the wide application of BIM technology, more and more companies are willing to adopt the 3D dynamic construction technology demonstration method to interpret the construction technology in the project. However, at present, there are still some defects in current construction process animation, such as low reusability, complex adjustment and long production cycle. By analyzing the technical advantages and disadvantages of text, sequence, static display, dynamic display and BIM model in the construction technology display, and combining the perspective of sharing multi-source data, we can achieve the precise creation of "text + picture + BIM model + video" four-in-one construction technology big database.
