63 The Office of Government Commerce (OGC) maintains a database of central government public sector construction projects, with information on key performance statistics updated biannually. The sectoral mix and project size are not directly comparable to our non-PFI data, however, PFI projects can be excluded to provide general performance statistics for public sector construction and show trends over time.
64 We have analysed OGC non-PFI data over the period of 2004 to 2008, in which time over 400 non-PFI projects were completed, 95 per cent of which had a capital value of under £20 million.
65 OGC data shows 60 per cent of public sector construction projects were delivered to timetable and 54 per cent to price between 2004 and 2008 (Figure 12). These statistics are in line with the NAO's non-PFI survey results to price though performance to timetable is lower in the OGC figures. The OGC data do not show any clear trend in the price statistics, but there is a downward trend in performance to timetable.
66 Twenty projects from this dataset had a capital value of £20 million and above. These projects delivered to timetable in 55 per cent of cases and to, or under, the contracted price in 50 per cent. This is in line with the OGC statistics for all projects and not dissimilar to the NAO non-PFI survey results, though performance to timetable is lower for these projects.

1 A weighted average has been calculated for 509 projects with time performance data, and 408 with price performance data, as the number of projects completed was spread unevenly over the five year period. | ||||||
