In order to better adapt to the needs of construction and modern construction development, to solve the problems existing in the traditional construction mode, the gradual transformation of construction enterprises to intelligent construction mode has been the general trend. Aiming at the requirements of intelligent construction in the new era and new infrastructure and combining with the theory of capability maturity, an application maturity evaluation model of intelligent construction based on combination empowerment and cloud model is proposed. First of all, from construction, intelligence and other three dimensions, the intelligent construction application maturity evaluation system is constructed, which includes seven categories: survey, design planning, construction site management, resource elements, intelligent construction technology, data-driven and enterprise top-level design. Secondly, G1 method and entropy weight method are used to determine the subjective and objective weights of each index, and game theory is used to combine the weights. Finally, the cloud model is used to show the application maturity level of intelligent construction in construction enterprises, and the outlook is made according to the evaluation results. The case study results show that the evaluation level of intelligent construction application maturity in construction enterprises is "integrated sharing level". The evaluation results are consistent with the actual situation of the enterprise, which verifies the applicability and scientificity of the method in this paper and provides a scientific basis for the development of intelligent construction application in construction enterprises.
