praised as creative, many reviewers also believed the tower could be covered in masonry to blend in with neighboring buildings, or that its height should be reduced for the same reason. The city ultimately accepted this design. Construction HRH Construction was hired as the contractor on Trump Tower. The company would go on to build many of Trump's other real-estate developments. HRH hired several dozen subcontractors to work on different aspects of the building. Barbara Res, who had worked on some of Trump's other projects, was hired as the construction executive in October 1980. She had previously worked for HRH Construction during the building of the Citigroup Center and the Grand Hyatt. Res was the first woman assigned to oversee a major New York City construction site. She was often ignored by subcontractors and suppliers who were new to the project, as they thought the person in charge of construction was a man. The head superintendent of the project was Anthony "Tony Raf" Rafaniello, who worked for HRH Construction. He was in charge of coordinating construction based on the site's blueprints. Rafaniello was supported by five assistant superintendents, including Jeff Doynow, who was one of the first "concrete supervisors" to be hired for the construction of a skyscraper. After Rafaniello was hired for the Trump Tower project in September 1980, he spent a week planning a three-phase construction schedule. Once the subcontractors were hired, Rafaniello made sure they met once a week to ensure they were working on the same phase. Trump Tower's proposed mixed-use status posed obstacles during construction since there were different regulations for residential, commercial, and retail spaces. Several prospective commercial and residential tenants requested custom-made features, including the installation of a swimming pool for one unit, and the removal of a wall with utilities inside it for another. Trump's then-wife, Ivana Trump, was involved in selecting some of the tower's minor details. Donald Trump and Res agreed to fulfill many of these requests, but they did not always agree on matters of design. In one case, Trump so hated the marble slabs at some of the tower's corners that he demanded they be removed completely, even at great cost; he eventually decided bronze panels should be placed over the marble, but Res later said she refused to buy them. Trump Tower was one of the first skyscrapers with a concrete frame, along with Chicago's One Magnificent
