Victorian corruption investigators have laid more than two dozen fraud charges against the former construction manager of the $630 million Bendigo Hospital project after a long investigation.

Bendigo Health's former construction manager Adam Hardinge has been charged by the Independent Broad-based Anti-corruption Commission two years after Fairfax Media first revealed corruption allegations involving Victoria's largest regional hospital development.

The charges against Mr Hardinge, which include obtaining property by deception, were laid over allegations he misused his position overseeing construction on the state government project.

IBAC has been investigating allegations involving Mr Hardinge and another former senior figure, who has also left Bendigo Health but who has not been charged.
