Two former city officials pleaded guilty yesterday to bribery charges for accepting tens of thousands of dollars from contractors seeking to secure lucrative government contracts.

Michael Provenzano, 49, who worked as construction-services director at the Department of Housing Preservation and Development, and Luis Adorno, 48, a supervisor in the agency’s Architecture and Construction Engineering unit, both admitted they received the illicit payments in exchange for helping contractors.

Yesterday’s guilty pleas before Brooklyn federal Judge Nina Gershon mark the latest development in a sprawling corruption case against the city agency, which finances the construction and renovation of affordable housing.
