The 10 key performance indicators, which are backed by construction minister Nick Raynsford, are intended to show whether industry is meeting the improvement targets set out in the Egan report.
Clients are keen to see the indicators used to produce league tables of firms. But they say such tables, which will help them choose suppliers, are at least a year away.
The indicators are based on benchmark data from the DETR, Construction Clients Forum, RICS and firms’ financial results.
Contractors and consultants will also use the scheme to measure their own performance. They will be able compare themselves against the benchmark data, which is presented on a series of graphs.
However, firms are concerned that rivals will present data only for their best projects, thus creating a false picture of the industry.
Alan Crane, who chaired the working party that produced the indicators, admits that dishonest data would be a problem. But he said: “I don’t see why people should cheat. They will only kid themselves.”
