The World Building, Manhattan Life Building and Park Row Building occupy a weird gray area in the ‘world’s tallest’ timeline. In this case I’m pretty sure they exclude religious buildings since there are things like the Ulm Minster that were hella tall, but most of their height is just hollow space or reserved for bells. So technically as an over 50% habitable office building, it was the tallest.
The only exception is Philadelphia City Hall. Depending on whether you count it’s year of completion as 1894 or 1901, that variable could wipe Park Row off the list, as it was technically taller but not totally completed until 1901. The Singer Building undeniably wiped the floor with them in 1908 as the tallest and put an end to the grayness since it was only up from there.
Isn’t it weird that we also don’t see any of those metal clippings that hold the cladding into place? There’s metal frames built around the perimeter of the slabs and columns, but that’s all I see
Facade clips are only used on unitized curtain wall panels that are hung in place in pieces, this building doesn’t seem to be using that method of facade construction, which is not unusual by any means.
The windows will just be fitted into the opening much like residential/house construction and the entire building will be waterproofed with painted on waterproofing, the white “frame” extrusion will just be built up from the surface of the concrete. This is actually a more typical/traditional way of facade installation seen around the country.
