Planned construction times and labour utilization — a comparison of UK and French contractors

Abstract

The results of a model based survey of contractors' planning engineers in France and the UK suggest that planned completion times for constructing an identical high‐rise in situ concrete framed structure are significantly and dramatically lower in France than in the UK. Average planned construction periods in France were 13 weeks, some 9 weeks faster than the UK average of 22 weeks. Since planned construction periods reflect past experience, French contractors apparently achieve superior levels of production performance whilst at the same time working fewer hours per week, utilizing directly employed workers and employing fewer supervisors. If such planned completion times are truly representative, the findings indicate comparatively poor UK contractor performance, and signify future problems for the British builder in the emerging European marketplace. The causes of such poor performance are complicated, but based on indicative French best practices: production is enhanced when scheduled overtime is avoided, a directly employed and mainly skilled workforce is engaged, and a maximum working time of 40 hours per week is the norm rather than the exception.
