$17.8 million for work they performed for the university.

No corruption findings were made against the three companies which gave "full and frank evidence" but the ICAC found Mr Hood engaged in corrupt conduct by providing money to Mr Faysal.

The remaining monies paid to Mr Faysal were in the form of $41,000 in overseas travel from Rega Controls for himself and his family.

Another UTS supplier, Targetti Australia, provided overseas travel to him worth $61,000, the ICAC found, and elsewhere, he accepted an Apple iPad and a chair worth about $2500.

Faysal also undertook private work for Webster Wagner Engineering, a company interested in performing work for UTS, and deliberately failed to disclose the conflict of interest.

In 2010, he was investigated and counselled by the university for breaches to its policies.

Hewas suspended but, when he returned to the area in which he worked, a major restructure created opportunities for him to influence UTS staff to direct work to companies able to provide him personal benefits.

The university sacked him in April 2012 but he launched proceedings with Fair Work Australia against his dismissal.

"The ICAC is of the opinion that the advice of the Director of Public Prosecutions should be obtained with respect to the prosecution of Mr Faysal for offences of soliciting and receiving corrupt benefits," the ICAC said.

The corruption watchdog also recommended UTS strengthen its procurement practices.
