Through the construction of a reasonable comprehensive evaluation framework, it aims to coordinate the commonly used management forces and means of existing engineering construction, objectively and reasonably evaluate the general contractor’s behavior and project construction effect, solve the practical problem of difficult owner supervision under EPC mode, and promote the popularization and application of EPC mode in China.
