Is this going to have an Observation deck? There seems to be a dearth of Observation decks in San Francisco.

^I don't know, but that would be great.

As for whether crowns and spires are included in the height of a building, I agree. I was just saying that the roof of the transbay tower is at 912 feet, or 970 to the top of the mechanical penthouse. With the crown, the total structural height is 1,070 feet though.

so are spires, but not roof height.

US Bank will still be the tallest tower (roof Height) in W. USA.

However Transbay is the only building on SSP which's solid parapet they don't count, so I'd say this is an error since there are thousands of buildings on SSP for which their solid parapet is counted towards roof height

The general consenzus on SSP is that solid parapets are counted towards roof height and I agree with it

That's not true. The correct height of 1,070' is listed on SSP, and it's not the only building where the roof height is listed separately from the total height. Crowns/parapets/spires aren't "the roof" in architectural terms....they go on top of the roof. They're included in a buildings height obviously, but roof height is always going to be lower than the total height of a building when crowns/parapets/spires are involved. The US Bank tower in LA will still have the tallest roof on the west coast, but it won't be the tallest building on the west coast anywhere.

Not exactly, solid parapets and solid crowns are part of a roof and therefore count in roof height. Open air parapets, open air crowns, spires and antenna are additions on top of a roof. The other buildings (other than Transbay) on SSP for which they don't count parapets all have open air parapets and these are not part of roof height. Those that have solid parapets have them counted towards roof height in 99% of their drawings

I hope this helps and don't be frustrated with forumers who are mean to you cause none of us, not even them have ever browsed through an entire thread just to get answers. If you need any info, just ask, there's nothing bad about asking
Thanks buddy. I appreciate your generosity.

These two buildings will forever change and bring a new dynamic to SF and LA....hopefully for more "out of the box" designs.

LAYNE CHRISTENSEN ANNOUNCES $19 MILLION GEOCONSTRUCTION CONTRACT
By GlobeNewswire, September 18, 2013, 12:30:00 PM EDT

THE WOODLANDS, Texas, Sept. 18, 2013 (GLOBE NEWSWIRE) -- Layne Christensen Company(Nasdaq:LAYN) ("Layne") today announced that its Geoconstruction Division received a contract to provide specialized foundation work in connection with the construction of Transbay Tower in San Francisco.

The contract has an estimated value to Layne of approximately $19 million. Work on the project is expected to commence in October 2013 and last approximately 6 months.

Transbay Tower is a 1.3 million square-foot, 61-story skyscraper that will become the centerpiece of a 145-acre, multi-purpose development in downtown San Francisco. The tower, which will be built adjacent to the Transbay Transit Center, is slated to become the tallest building on the West Coast, rising to a height of 1,070 feet.

Layne's Geoconstruction Division will install the building foundation system by the use of LBE (load bearing elements). Seated approximately 245 feet deep, these LBE are designed to support vertical loads from the building framing system and transfer them to the foundation.

Rene Robichaud, Chief Executive Officer of Layne, said, "Layne's selection as a contractor for this landmark project is a recognition of our world-class ability to offer specialty foundation construction services in a safe and sustainable manner. We are excited to be a part of a project that will help transform San Francisco's skyline and form the new heart of a revitalized neighborhood."...

From the renders I saw it looks like Wilshire will have an open air lattice crown and those are not counted towards roof height

what do you mean by open air. The Wilshire Grand crown will have a helipad (small squared) on the top of it, just over 1,000 ft.

He means that it won't have walls. It's kind of a weird distinction, to be honest, but that's personal taste. Kanto's definition isn't what the CTBUH uses. In fact, they don't recognize "roof height" at all, but rather only Architectural Top (which includes spires), Highest Occupied Floor and Height to Tip.

The crown definitely has walls, how else would it be standing, there is a stair case inside the crown to the top where the pad is located at.

I mean that it's an open framework... although I've just gone back and looked at it more closely and it does appear to be covered in glass in a way that I didn't remember (not that a glass curtain wall is holding anything up). That in mind, Kanto, the Wilshire Grand crown is looking more, or at least equally, deserving of rooftop status when compared to the Transbay parapet.



Edit: Although, I will eat a damned horse if there ever actually land a helicopter on that thing. It looks WILDLY unsafe.

They have to make it usable, it can't just be for show or to comply with municipal law. Scary though, you might have to eat that horse

It looks like the crown has been refined, at least according to the new renderings on Cesar Pelli's site:

the steel underneath the helipad (on top of the crown) looks strong enough to me to support the weight of a heli.

I've been out of town and not been able to drive by the construction site. Did I see a picture somewhere that there is some minor pre-construction/construction prep activity going on? Is there? I will definitely try to get some pictures this week of the site... There is an astounding amount of construction going on in the area. Quite an exciting time for San Francisco!
