Using Purchasing Power Parity To Assess Construction Productivity, Rick Best Sep 2013

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 Cost And Productivity In Construction: A Bad Example, Rick Best

In a report published in June 2012 the Business Council of Australia (BCA) reported that it costs considerably more to build a variety of types of infrastructure in Australia than it does in the US. Airports (90 per cent more costly) and hospitals (62 per cent) were quoted as the worst cases with other projects ranging from 26 to 43 per cent more. They used these figures to conclude that Australia is a high cost, low productivity environment for building infrastructure projects. These claims were based on cost/m2 figures published by a major international construction consultancy. The method used by …
