Aside from Carillion, there are few other surprises in the CAT scores (see table). The Agency's most successful contractor Balfour Beatty came out top in the assessment, scoring 187.2 having delivered 15 schemes in the past ve years. Contractors Costain and Vinci Construction Grand Projets were second and third with scores of 186.1 and 184.3 respectively.
Top-scoring consultant Atkins is also the Agency's most relied upon consultant. It has delivered eight major contracts in the past ve years and scored 183.8, putting it fourth overall. Jacobs and Arup were fth and sixth, with Alfred McAlpine, Ringway, Halcrow and Nuttall rounding out the top 10.
Up-for-sale Amec was bottom with 156.7, followed by URS Corporation and White Young Green.
Some consultants question whether the tight grouping of scores between 156 and 187 rendered the whole process pointless.
Others question the cost of carrying out the exercise, which for some rms ran to millions of pounds. But most rms said that the process was nevertheless a useful audit of internal processes.
