Nothing above ground?

Doesn't look like this building will be finished by 2017. They still haven't built anything above ground yet.

Maybe not, but once it gets above ground the construction will definitely speed up, trust me... look how fast 1wtc went up

There's a tower crane on site now:

There's been a delay in getting aboveground, because a couple of the caissons failed stress tests and needed to be redone, but I'm guessing they'll be going above ground soon enough, seeing as they just installed the crane.

I mean if you get rid of the bureaucratic bs It took like 4 years of actual construction.

Wow! I've never seen such massive wall supports as here. Is the ground really that unstable there? It's crazy to build skyscrapers in an area with such loose ground, and in an earth quake zone.

So, looks like the building won't be finished until 2018 or 2019?

Maybe not totally completed, but if the structural steel, and core are at street level by, say February of next year, it could still top out by January, 16, it took almost a year to the day, to erect the U.S. Bank tower in downtown Los Angeles, this tower with a comprehensive framing plan, and all structural steel, here, we have a xerox copy in the Salesforce tower, of Constanera Center, in Santiago, Chile, (also in a seismic zone) this tower went up in less than a year, (not counting the period it was on hold) and both towers have the most simple framing plan, it should go up rather quickly,

this opinion is based on a pure construction standpoint.....

The foundation isn't great, as this site was originally in Yurba Buena Cove. The original shoreline of SF was expanded a lot before and after the 1906 earthquake.

But yes it feels like the foundational work is taking forever.

This tower started less than 2 years ago and will likely be finished in 2 on schedule so that also is about 4 years or less.

But this is earthquake country. The foundation work is critical and especially in downtown which is mostly fill (they found at least 1 old ship digging for the terminal next to this tower). So pilings have to go to bedrock (in this case I think that's about 270 ft give or take) and the rest of the foundation has to take an 8+ quake without damage that might hurt people.

What this means is that about half the construction time on all downtown towers seems to be spent on the foundations and that appears nearly done on Salesforce now because they haven't been digging deeper for some time now and generally they don't install the crane until they are about to go vertical.

No. It will be ready in 2017 or at least so far there's no reason to think otherwise. And I am sure Salesforce.com wants to move in soonest plus they are probably about to announce other tenants.

You guys are all kind of annoying with your impatience. Having watched lots of construction here, I know the foundations do seem to take a long time and then the building seem to spring upward when that is done. But it's a fact the earthquake factor also means that the framing and everything else must also be engineered to the max--I am used to comparing buildings here to those on the East Coast and the ones here seem much more heavily built which takes time.

Unless Chicago Spire was leased up to tenants anxious to move in there's no comparison.

I just checked: Boston Properties closed on the lot and ceremonially broke ground in March 2013. I didn't keep flipping through pages to see when they actually started the foundation work but my guess is another couple of months--so it's been under construction very close to 2 years and is still scheduled for completion in "late 2017".

Once this gets to the repeating office floors, it will shoot out of the ground! The foundation and first few floors take forever in every building due to the compexity.
