The invention discloses a steel structure delivery and matched detection early warning method based on BIM technology. In a visualized three-dimensional BIM model, steel members are directly selected and used to generate matching early warning packages sequentially according to a steel structure on-site installation matching principle. When the finished steel members are not delivered in a matched manner in a warehouse-out phase, automatic early warning of a system is carried out, and passive management is changed into active intelligent management. Operators can find out problems during a loading process, and are aware of the missed delivery and the wrong delivery of the steel members, and therefore an unfavorable condition of on-site workers and on-site machines waiting for delivery of materials caused by the unmatched members is prevented. Management level of production factories and construction sites is improved by using an informatization way, and therefore wasting of construction resources is reduced, information transmission accuracy is high, timeliness is good, and an object of realizing refined management is achieved.
