Using Purchasing Power Parity To Assess Construction Productivity, Rick Best
Rick Best
For many reasons comparing construction productivity between countries is a difficult task. One key problem is that of converting construction costs to a common currency. This problem can be overcome relatively simply by using a basket of construction materials and labour, termed a BLOC (Basket of Locally Obtained Commodities), as a unit of construction cost. Average BLOC costs in each location are calculated from data obtained from a number of sources (quantity surveyors, estimators). Typical building costs obtained from published construction cost data are expressed in BLOC equivalents. Lower BLOC equivalents represent higher productivity as other inputs (largely materials) are …

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 reported. 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 …
