Abstract:  
           
          New management thinking like that of lean construction has 
          suggested principles and techniques that can result in better
          project performance. This paper aims to demonstrate the conceptual
          benchmarking principles for construction labour productivity and
          implement these in some projects in Greece, by the use of indices
          and measures of benchmarking in labour productivity. Indices such as
          the disruption index (DI), performance ratio (PR), project management
          index (PMI), and project waste index (PWI) are calculated. From the
          application of the above indices it was concluded that the benchmarks
          of labour productivity was found to be an important delineator
          between good and poorly performing projects.
