The invention relates to a constructional-engineering main contractor enterprise BIM standard compilation method. The method comprises the following steps of (1) building a graphical representation of a BIM model LOD grade; (2) constructing a BIM model creation collaboration mode; (3) building a BIM design model; (4) adjusting the BIM design model till that a construction drawing standard is satisfied and a drawing is generated; (5) according to an application depth, converting the BIM design model into BIM models of different stages; (6) carrying out butt joint on information of the BIM models of the different stages so as to form a three-dimensional BIM model; (7) establishing a rapid model display optimization scheme and carrying out three-dimensional BIM model display; (8) carrying out various kinds of BIM software integration optimization on the three-dimensional BIM model; and (9) according to the optimized three-dimensional BIM model, establishing a project-level BIM implementation scheme. Compared to the prior art, the method of the invention can be used to increase enterprise BIM standard compilation pertinence and an application life force, which is convenient for each level of BIM workers to apply and grasp.
