Capita Group, the parent of property and infrastructure consultant Capita Symonds, reported a turnover of 拢845m for the six months to 30 June, up 23% on last year.

Pre-tax profit was 拢85.1m, up 21% on last year鈥檚 figure of 拢70.1m.

In his chairman鈥檚 statement, Rodney Aldridge said Capita Symonds was now the fifth biggest multidisciplinary consultant in the UK. However, he also noted that the subsidiary鈥檚 margins were lower than last year because of the company鈥檚 withdrawal from the Dubai Rapid Road Link project.

The margins are expected to recover in the second half of the year.

Capita 鈥� which is essentially an outsourcing group 鈥� also confirmed Aldridge鈥檚 resignation from the company on 31 July. Eric Walters, who has been a director at Capita for five years, will replace Aldridge.

Under Aldridge鈥檚 chairmanship, the group has grown from a start-up in 1984 to a FTSE 100 company today. Staff numbers have risen from 98 to 26,000, and it now has a client base of 25,000 organisations across the UK.

鈥� Cintra, the transport infrastructure subsidiary of BAA鈥檚 probable new owner Ferrovial, reported a 23% increase in revenue to 拢266.3m in its interim results.
