In order to set up evaluation model and criterion, the index system of construction project standardization level were designed by induction. The index system consists of 4 first-degree indexes: Standard level Indexes, Implementation Indexes, Benefits Indexes and Efficacy Indexes, and 14 second-degree indexes. Then some evaluation method were analyzed by antitheses, combining weighed method were put forward to solve weighted calculation of all indexes and grey multi-hierarchy comprehensive evaluation to solve evaluation of efficacy indexes. Finally one composite index can be got to measure construction project standardization level.
