Zaha Hadid’s One Thousand Museum Has Topped Off

It’s official: Zaha Hadid’s One Thousand Museum is now topped off.

On Friday, contractors hoisted a giant American flag, and hosted a topping off party with construction workers to mark the occasion.

Workers were told they have seven and a half months to go. Full completion is scheduled in about ten and a half months, on about December 21, according to the project website. Groundbreaking took place in December 2014.

The official top off height is 709 feet, or 60 stories.
