NEW YORK CITY-The head of the New York Public Library at a State Assembly committee meeting on Thursday said that the library would commission a study to determine if the $300-million renovation cost to its flagship branch is too high.

“We know there is skepticism about our numbers,” Tony Marx, president of the New York Public Library told state lawmakers. “We understand that there needs to be an independent cost estimate and will provide one as soon as we have a design.”

Although the library in December estimated the renovation cost at $300 million in unveiling a design by British architect Norman Foster, Marx said Thursday that the design and cost of the project were subject to change and more specifics would be released in the fall, according to the New York Times.

The renovation, known as the “Central Library Plan,” will be funded from $150 million from the city and more than $200 million in expected proceeds from the sale of the Mid-Manhattan Library and the Science, Industry and Business Library. See story in the New York Times.
