An investigation by the Office of Fair Trading (OFT) into bid rigging in the construction industry has broadened to take in 150 firms, including Kier, ROK and Galliford Try.

Kier announced that it had been informed by letter last week that it was under investigation. After the disclosure Rok and Galliford Try confirmed on Wednesday that they were also under scrutiny.

More large contractors are expected to announce that they are under investigation in the coming weeks.

好色先生TV has learned that the competition watchdog has contacted 150 firms in connection to the inquiry into construction cartels. More than 50 offices have so far been raided.

Kier said 20 tenders made by Kier Regional between 2000 and 2005 were under investigation. The firm鈥檚 share prices fell 7% from 拢24.25 to 拢22.54.

Kier says it won only four of the 20 tenders, worth about 拢13m. It notes that it has bid for about 11,000 tenders in the five-year period and secured contracts valued at about 拢24bn.

Rok said two subsidiaries it has acquired were being looked at by the OFT for an unspecified number of tenders. One was under investigation at the time of the acquisition, and the other was first examined a year before Rok bought it.

Punishment for firms found guilty of collusion could be as much as 10% of global turnover

Galliford Try said 17 tenders made by its building division between 2000 and 2005 were under scrutiny. The company said the tenders represented a 鈥渧ery small proportion鈥� of the division鈥檚 bidding activity.

Galliford Try鈥檚 announcement came hours after Rok鈥檚, although a company spokeperson said it had planned to announce its involvement before Kier or Rok had done so.

A Kier spokesperson said the company felt it had a duty to inform the stock exchange. He said: 鈥淭he kind of company Kier is means being open about these things.鈥�

The OFT investigation has been running for two years and inspectors have been to 57 company offices. Kier, Galliford Try and Rok have not had any offices raided.

OFT rules dictate that those under investigation are forbidden from contacting other companies about the inquiry. As a result there has been uncertainty in industry circles over the extent of the probe. One director said: 鈥淲e don鈥檛 know what they鈥檙e going to do, and we don鈥檛 know when it will end. Frankly, you probably know more about it than we do.鈥�

Punishment for firms found guilty of collusion could be as much as 10% of global turnover. For a company of Kier Regional鈥檚 size, that could mean fines of 拢100m. Directors could face five years in jail, although this sanction has never been applied.

The OFT has used digital forensics for the first time, which means it has been able to search for deleted or hidden documents on seized computers.
