69 KPI Zone is an annually updated database on key performance indicators reported by construction projects. It covers the whole construction industry in the United Kingdom, including public and private sector projects, many of which are under the £20 million threshold we used for our PFI population.
70 KPI Zone data show 58 to 65 percent of all industry construction projects were completed to timetable and 44 to 52 per cent to price between 2003 and 2008 (Figure 13). These statistics are in line with results from the NAO's non-PFI survey. Performance data over time from 2004 to 2008 do not show a clear trend to timetable or price.
71 Though the four UK sources presented in this section are not directly comparable to one another, as they are drawn from different populations, they do indicate that non-PFI public sector construction projects are delivering to timetable in around two thirds of cases and to price in around half.
72 We also contacted a number of international audit offices with the aim of gaining an international comparator. The only similar study we received was a report on PFI and non-PFI performance in Australia by The Allen Consulting Group8. We reviewed this report as a potential international comparator, but we found that the statistics were not defined in a comparable way so as to be useful to this study.
