The invention discloses a building masonry construction method based on the building information modeling (BIM) technical. Firstly a design paper is read;then uniform establishment rules, naming rulesand data interaction formats are determined, then a BIM model is established, model collision inspection among architecture majors, structure majors and electromechanical majors are conducted, and collision positions are optimized; model deepening of a wall body member,brick layoutmodel deepening, and pull wall reinforcement model deepening are carried out successively; and after brick layout model deepening is finished, a wall body position number chart, a wall body brick layout chart, and a masonry need table are issued according to the BIM model; the accuracy of the model is re-checked, construction process animation simulation disclosure, deepening chart disclosure, model disclosure are provided for construction management personnel and masonry operatingpersonnel, and finally, masonryconstruction is carried out centrally. According to the building masonry construction method, the three-dimensionalmodeling and modeling combination technology of BIM is used, application deepening is conducted on a BIM model management platform, effectiverequirements information is extracted, centralized processing is conducted on the site of building masonry construction, and the efficiency isimproved.
