He also said the inquiry against former state PWD Minister Chhagan Bhujbal in the Maharashtra Sadan scam would be completed within a fortnight.
"Both Pawar and Tatkare were under an illusion that they could evade the ACB inquiry," Somaiya told reporters.
"They chose to ignore ACB summons several times. But, they had to present themselves after a stern show-cause notice," he charged.
The inquiry would be completed in eight to twelve weeks, while Bhujbal's case would be decided in two weeks, he said.
Somaiya said he had written to Union Finance Secretary, RBI Governor and CMD of Union Bank of India Arun Tiwari stating that the investigating agencies have found several non-transparent transactions, including scandalous appointment, cost escalation, money laundering by FA constructions and the "bogus" companies owned by Pawar and Tatkare.
The BJP leader demanded action by RBI, Union Bank, Income Tax and Enforcement Directorate.
Malik alleged that BJP was trying to divert attention from the government's failures in the last one year.
Pawar and Tatkare are under scanner for allegedly awarding tenders to contractors by flouting norms which resulted in massive cost escalation for several irrigation projects during the Congress-led Democratic Front government.
