In a bid to speed up its probe, the CVC has asked the chief vigilance officers of government departments to prepare a list of officials who were allegedly involved in corruption while executing Commonwealth Games related projects.

It has also asked all civic and construction agencies to put documents related to the Games works carried out by them on CVC's website.

A special team of the commission probing the Games related work for alleged graft has found evidence against senior government officials for rigged tender process, undue haste that led to supply of inferior quality products and poor construction of infrastructure related works.

Sources said the commission will make a department-wise list of such 'tainted' people who were involved in the corrupt practises to take speedy corrective action.

"There have been several complaints from non-government organisations and whistle blowers claiming that host of government employees were involved in corrupt practises. We have sent the complaints to concerned CVOs for investigation and report," a CVC official said.

He said a complaint has also been sent to the CVO of sports ministry to probe the role of certain incompetent officials involved in carrying out infrastructure related works.

Sources said the CVC has found series of financial irregularities on part of certain government employees from departments like central public works department (CPWD), public works department (PWD), municipal corporation of Delhi (MCD), New Delhi municipal council (NDMC), Delhi development authority (DDA) and Games organising committee among others.

They said the watchdog has received a number of complaints alleging that various "incompetent" people were involvement in several projects that led to unjustified cost escalation and corruption.

The move assumes significance as prime minister Manmohan Singh appointed high level committee under the chairmanship of former comptroller and auditor gGeneral V K Shunglu has found series of wrong doings by government officials.

The committee has faulted sacked OC chief Suresh Kalmadi and secretary general Lalit Bhanot for their alleged involvement in irregularities. Besides Delhi Lt governor Tejinder Khanna and chief minister Sheila Dikshit were blamed for alleged inadequacies in CWG projects.

According to an RTI filed by PTI, the commission is looking into at least 40 CWG-related construction and procurement works carried out by different government agencies for alleged financial irregularities.

An analysis by chief technical examination wing of CVC had earlier found alleged financial and administrative irregularities worth about Rs 2,500 crore in 16 construction and procurement projects.

Six of them were done by PWD, three by MCD, two each by CPWD, DDA, NDMC and one by RITES, a government of India enterprise, a CVC report said.
