The invention provides a construction method of guiding an informationization prefabricated member based on a BIM (Building Information Modeling)) technology. The construction method comprises the following steps: step 1, carrying out three-dimensional modeling; step 2, detecting collision and optimizing adjustment; step 3, carrying out production construction simulation; step 4, generating a detail list; step 5, generating construction cost information; step 6, performing information statistics; step 7, prefabricating and machining; step 8, manufacturing a two-dimensional code label; and step 9, marking the prefabricated member with a two-dimensional code. The BIM technology and a two-dimensional code technology are combined in house industrialization and the two-dimensional code label is stuck to the prefabricated member; when a two-dimensional code instrument is used for scanning the two-dimensional cod, construction cost information and material utilization conditions can be known and the production of the informationization prefabricated member can be realized; and personnel allocation of three major parts including member design, member configuration and member production is clear and a production process is reasonable.
