270 Park Avenue’s First Office Levels Begin Formation in Midtown East, Manhattan

Construction has reached the first office levels of JP Morgan Chase‘s new 1,388-foot supertall headquarters at 270 Park Avenue in Midtown East. Steel assembly on the gargantuan ground floor has reached the eastern end of the rectangular parcel, while the rest of the flaring diagonal columns complete the outline of the base. This week, workers began to weld the first set of vertical columns and diagonal beams above the ground floor, which will become trading floors in the first tier of floor plates in the 2.5-million-square-foot behemoth. Tishman Construction is the general contractor for the project, located between Park and Madison Avenues and 47th and 48th Streets.
