The construction of project cost index system was the work of summarizing the previous data to achieve the purpose of guiding future work. This paper introduced the types and data sources of project cost index system, and put forward the compilation method and content of project cost index system. The project cost index system should be compiled according to the hierarchical structure of “construction project-regional project-single project-unit project-subentry project”. The specific contents included engineering overview, construction cost index, equipment price index, single project cost index, etc. The cost index system should be updated and maintained by means of information technology.
