They did it in the late 80's to a medical tower in sandy springs near north side and 400. They only add floors if the building's existing structure can accommodate it. The elevators can be tricky and relocation of any utilities on the roof is a hassle. I really doubt they would spend 88 million on only 6 floors. It has to include other improvements. It would not make business sense.

Blue Cross Blue Shield did a 24 story addition onto their tower back in the 2008-2009 era and that cost $240 million at that time for a 24 story addition, so the cost provided by the campanile expansion is high, but not that high. I'm wondering if its the addition of 6 stories, reno of the existing building and then the retail portion. No way there is enough in there to cover a completely new tower.

The big difference would be the the BCBS building in Chicago was designed to be expanded in the future. Was the Campanile? Doubtful, considering it used to have a crown.

I guess it depends a little bit on the weight of the crown. It could be that by removing the crown, they are able to add the new 6 floors using improvements in construction since it was built (Lightweight concrete, lighter cladding, etc).

That's all speculation, but I'm guessing that is what may allow the addition. Still doesn't make it easy though

I think most buildings when built are overspeced to allow more weight than needed, so adding a few floors on the top is not an issue. I know certain density concrete is needed for taller structures but engineers can figure out how much additional weight a structure can hold.

This is actually quite a common practice, in some places anyways. Not to namedrop other cities in this thread; however, in Rochester, Minnesota which is a medically driven city/community, they commonly build for it. Several of the mid and high-rise buildings are built to later accomidate further vertical expansion. Throughout the city, several buildings have undergone vertical expansions years after they were completed.

The most notable example would be the Mayo Clinic, more specifically the Mayo Building itself, which was originally built up to 12 floors in 1955; however was later expanded to 20 floors in 1968. Even the Ghonda building which was completed in 2001 and connects to the Mayo building which topped out and currently stands 21 floors was built to further accomidate an additonal 10 floor expansion when it will be needed. When and if such an expansion is implemented, that building would surpass the current tallest building in St. Paul, MN by height.

Pretty sure its a screen shot (cropped from approx. the 1:23 mark) from the video that was posted below the photo.

Pemgin · #**5591** Posted **Oct 25, 2017, 4:22 PM**

That shot is a great reminder of the assload of parking decks we have and are still building. That Standard deck...jesus.

NCR Phase 2 looks topped out now.

Folks in this forum are sooooooo damn dramatic...

Anyway, any update on:

- Opus
- SLS
- Eviva
- P'tree @ 17th
- 1105 W Peachtree
- 14th & Spring
- Atlantic Yards
- AMLI Market
- Star Metals

Not heard anything on these in awhile.

Opus's LD permit is ready to issue. Looks like they just have to pay the fees.

Walked along the new EST to Edgewood and got reminded studioplex development is in full swing. Should be a really nice addition to the Edge development going up at the same time. Has me really curious what they're planning for the O4W Georgia Power parcel and if/when more developments will come to the area. I'd like to see redevelopments on Krog St. NE and the surface parking just west of Ladybird, in particular. Despite the progress, the area is still demanding more infill.

I was looking at the Campanile building plans and thought it was odd how the building does not align with the street grid and it would be easier to densify the block if it did. Then I noticed that several other buildings in the area are aligned at the same 45 degree angle from the North-South grid. At first I thought they were aligning with the bend here in Peachtree Street, but that is also not the case.

Does anyone know why so many of these buildings share this alignment or if there is something they are aligned to?

Has to do with Stonehenge imo.

A new presentation on the southside Beltline is up. According to the document the design for the southside trail is 50% completed; Lots of interesting details about many aspects of the beltline work.
