PROVIDENCE — The owner of Rhode Island’s tallest building renewed an effort Monday that failed last year to get government aid to redevelop the downtown landmark.
The 26-story skyscraper 111 Westminster, known as the Superman building, became vacant in April when Bank of America moved out. It had been used as a bank since it opened in 1928.
Its Newton, Mass., owner, High Rock Development, last year proposed to turn the building into apartments, saying it would invest $55 million but needed $70 million to $75 million more in public aid. The plan went nowhere.
High Rock restarted the effort Monday, calling it a ‘‘public private partnership’’ and adding some sweeteners, including a guarantee it would complete the renovation before receiving any state investment.
