In the diagnosis researches on the implementation status of construction engineering projects (CEP), two major problems remain unsolved yet by far. On one hand, there is not a scientific approach to extract and determine the diagnosis indicators for the implementation status. On the other hand, it still lacks an effective method to analyze and diagnose the implementation status. As an improvement, in this paper these two problems are studied respectively. According to the three required conditions for the implementation status diagnosis, the determination approach based on quantitative scoring for the index setup is firstly presented. All of the indicators are transformed and standardized into the range value forms within [0,1]. Then, the recursive analysis method and model of the diagnosis indicators, which combines the model-based method together with the characteristic based method at the meantime, is proposed, and the grading judgment standards for the implementation status of CEP are presented based on the windage principle. Finally, an indemnificatory housing project which contains 21 residential buildings is taken for a case study to validate the proposed method. It is shown that the proposed method is able to effectively obtain the actual implementation status of large-scale construction projects and find out the exact problems as well as the targeted measures.
