The 99 Washington Street project is the tallest Holiday Inn in the Western Hemisphere and allowed us to employ a number of cutting-edge construction techniques. The out-of-the-ground project is 50 stories and 176,000 square feet, making up 492 hotel rooms and three elevators. To build the structure and maintain safety, we used, for the first time, a tower crane and a cocoon safety system. The latter was a first for any non-union firm and was specifically designed – in conjunction with specialized engineers – to prevent harm to the adjoining buildings, even during Hurricanes Irene and Sandy.
