Another Order to Vacate at Site Threatened by One57 Crane One of the more dramatic moments as Hurricane Sandy raged last October took place in Midtown Manhattan when hundreds of people were forced to leave their homes because the winds accompanying the storm had damaged the boom of a crane that loomed 1,000 feet above the sidewalk from a soaring residential tower under construction just south of Columbus Circle. Construction at a tower near Columbus Circle, where a damaged crane dangled during Hurricane Sandy, may yet again temporarily push out residents of Alwyn Court. The tower, known as One 57, is visible through the glass ceiling from inside Alwyn Court. Among those forced to vacate for nearly a week were residents of the 72 apartments in Alwyn Court, the stately apartment building at the corner of Seventh Avenue and West 58th Street. So, board members and other residents at the building were unhappy Friday when they received word from the city and the developer of the yet-to-be completed tower next door, known as One57, that they would have to leave their homes once again next weekend while the crane atop the tower was repaired. According to the city's Buildings Department, the operation would replace the boom damaged in the hurricane. "They are trying to lower the boom on us," said Joseph Baillio, 69, one of the Alwyn residents who stood on Saturday morning inside the Alwyn Court's spacious lobby. Speaking of Extell, the developer of the building, he added: "They are bullying us." The president of the building's co-op board, Paul Matus, 62, said that he had met with Extell executives and officials from the Buildings Department on Thursday to discuss plans to install a new boom on May 10 and 11 and told them that his fellow residents would be willing to discuss how best to accommodate the operation but wanted more time to plan. On Friday morning, he said, a Buildings Department official told him that the agency was planning to issue a vacate order to compel the residents of Alwyn Court to leave for about 24 hours starting next Friday night. Similar orders would also apply to another building, the Briarcliff, and to a nearby school, he said. Saying that the Buildings Department appeared to be working as "an arm of the developer," Mr. Matus said that he and other board members were considering asking for a court injunction to block the vacate order. Mr. Matus said that Extell officials had told him that they would reimburse the Alwyn Court's residents up to $1,000 to relocate temporarily on Friday. But Mr. Matus added that it would be difficult for many residents to find lodging, particularly those who would not want to leave dogs, cats or other pets behind if there was a chance that their apartments might be damaged. "We feel like our backs are up against the wall," he said. Also dismayed by the prospect of a shutdown next weekend was Alexandre Petrossian, one of the owners of Petrossian, a restaurant on the ground floor of the Alwyn Court. "It is very painful," he said, adding that the restaurant had many reservations for Mother's Day weekend and was in the unenviable position of telling patrons that those reservations could not be honored. Mr. Petrossian said that he, too, was consulting with a lawyer. Tony Sclafani, a spokesman for the Buildings Department, said the boom replacement had been approved after an "extensive, thorough review" by the agency, the crane manufacturer and a third-party engineer. "The safest construction site is one that is completed," he said. The replacement of the boom will facilitate that process. Extell representatives did not immediately respond to a request for comment. Developers of One57 have presented it as one of the world's most exclusive buildings. It will rise to a height of 90 stories, offer sweeping views, and include top-floor apartments priced at $90 million apiece. When it was built in 1909, the Alwyn Court was one of the most lavish buildings of the day, according to the author Michael Gross, 60, who is a resident there. The building, long admired for its terra-cotta facade, went bankrupt in 1933, he added. Residents over the years have included the pianist and raconteur Oscar Levant and the producer Cameron Mackintosh.
