  • Abstract:
    The analysis of lost labour productivity claims on construction projects is a difficult undertaking at its best. One of the accepted methods of quantifying productivity losses is the use of industry standards and publications/charts. The sources of these publications are studies based on data from a large number of projects of varying conditions thus raising questions on their general applicability. The aim of this paper is to review the various published studies in a view to offer guidance to practitioners as to their proper applications. The review examines how they were carried out, their strengths and limitations, which will provide guidance to practitioners as to their proper applications. A major limitation identified was that each of the studies applies to a very specific project environment for specific trades only and that there are many other projects types for which productivity studies are not available. Furthermore, most of the studies were carried out in the US whose construction environment is different from that of the UK making their applicability here tenuous. The paper therefore outlines directions for necessary future research.
