The talents training of intelligent construction engineering requires optimizing practical teaching system. The construction industry is undergoing an overall transformation, three salient features can be observed, one is to derive the industrialization of construction from the scarcity of manpower, the second is to shift from pipeline products to parts and components, and the third is to shift from one-time delivery to full-cycle operation and maintenance. Correspondingly, civil engineering engineers also have new demands for their job-fitting capabilities, such as the engineering capabilities of applied talents, the collaboration capabilities of building industrialization, and the data capabilities of product services. Applying system dynamics theory, analyze the causal chain, enhancement loop, adjustment loop and feedback mechanism between the two major variables of training teaching and skill acquisition. The research results show that civil engineering majors in local colleges and universities can learn from the design teaching context, man-machine interactive platform and integration of production and education courses in three aspects, optimize the connection relationship of training elements, reconstruct the multi-professional full-cycle training teaching system, and meet the needs of intelligent construction talents.
