The invention discloses a detail hierarchy classification compilation method for hydraulic BIM model member delivery. Hydraulic BIM model members are classified and merged according to a BIM information similarity principle and major type members are formed; the model detail hierarchies and domestic design and construction phases are mapped to each other in a one to one manner according to definition of model detail hierarchies of hydraulic BIM model members and design and construction phase regulations in the field of hydraulic and hydroelectric engineering; content of graphic elements and non-graphic elements that are needed by the hydraulic BIM model members in different design and construction phases is stipulated according to precision requirements at different phases in the field of hydraulic and hydroelectric engineering. According to the hydraulic BIM model member delivery object detail hierarchy classification compilation method, the model detail hierarchies are used as core content for delivery object grading operation, and implementation standards are enabled to meet actual production demands; a BIM delivery object quality evaluation method, content, detail presentation and exhibition effect can be realized.
