Construction continues to rise on 270 Park Avenue, JPMorgan Chase‘s new 1,388-foot-tall, 70-story supertall headquarters in Midtown East. Severud Associates is the engineer of record and Mueser Rutledge Consulting Engineers (MRCE) designed the structural foundation elements for the 2.5 million-square-foot tower, which takes up a full city block between Park and Madison Avenues and 47th and 48th Streets.
Several office floors have been added since our last update at the end of December, when the flared base had recently finished. There are now four levels with metal decking standing above that point, and progress should pick up in the coming weeks as the weather gets warmer.

The construction elevator hoist facing Park Avenue has also climbed higher above street level, while the construction cranes should also follow suit.

On the western half of 270 Park Avenue is a flat cantilevering section that protrudes beyond the first office level, and wraps around the northern and western corners. The opposite eastern elevation does not have any steel connections that would indicate a replicated assembly.

So far the core of the edifice has yet to appear at the center of the project, but this should occur sometime in the coming weeks. Workers could possibly reach the first setback by the end of spring or early summer, and the superstructure could conceivably hover just below the halfway point by the end of the year. The gradual reduction in floor size should aid in the speed of construction.
270 Park Avenue’s completion date remains undisclosed, but is estimated to take several more years.
