Abstract:
International comparisons of construction industry performance are notoriously difficult. A recent comparative
study, extensive in scope and using an innovative approach, is reviewed and questions raised regarding various
aspects of the methodology adopted, the validity of the conclusions drawn and manner in which outcomes were
orted. Particular areas of concern include the unequivocal statement of conclusions that are based on a small
sample, and the use of data from that sample that are, in fact, no more than estimates of project performance.
Attention is drawn to the limitations of the research reported and the reliability of the methods used, and the
data gathered is examined.
