What's really remarkable about the whole Transbay project is the fact that it's bringing a whole highrise (or at least, midrise) boom to the Mission St. district: There are about four or five buildings in the 30+ story range that are currently under construction there. The whole face of the neighborhood will be greatly changed once all those projects are finished.
2017 is the completion date for the Terminal. I believe the intention is to complete both Tower and Terminal at about the same time (their design and architecture were coordinated). That may be why construction has begun at a leisurely pace (along with the need to find one or more anchor tenants).

While I too had my doubts (and expressed them) about funding when Hines was the sole developer, I have no such concerns with Boston Properties now in charge. Boston Properties is a REIT (Real Estate Investment Trust) which means they have access to public equity and debt markets. If they need development money, they put out a secondary issue of stock (or sell bonds). And they are among the most financially solid and respected of REITS, run by Mort Zuckerman (who also owns the New York Daily News).

Aside from the Transbay Terminal and Tower, there is the Transbay Transit District which largely is the vacant land created by tearing down and reconfiguring the ramps for the Bay Bridge approaches and, especially, its connections to the old Transbay Terminal. Following the 1989 quake, the western ramps to the Bridge have been almost completely redesigned and rebuilt freeing up much land.

New video from Boston Properties (coincidentally revealing the Tower's street address - 415 Mission):

Real estate blog Socketsite yet again today suggests the video in post 1163 above, by calling the Transbay Tower a "vertical campus", is calling out to a particular prospective tenant: Google. For a while now they have been saying Google is looking for a large new lease in San Francisco and the choice is between renting the Transbay or buying and building the low/midrise Ricardo Legorreta-designed campus in Mission Bay that Saleforce.com abandoned in favor of occupying 350 Mission St (under construction).

Still from videocam showing, in low center (from upper to lower) site of 181 Fremont skyscraper (with blue pile driver), a portion of the Transbay Terminal foundation construction (with red crane) and the Transbay Tower site (mostly dirt with scattered equipment)



535 Mission tower can be seen under construction in lower right corner of shot.

Excavation Complete at Transbay Transit Center in South Beach
Tuesday, February 11, 2014, by Michael Conrad

More than three years after first breaking ground, the future Transbay Transit Center has officially completed excavation. The four-block long mega project has dug, scooped and hauled away 640,000 cubic yards of dirt, or "the equivalent of 120 Olympic size swimming pools." Workers will now focus on completing the five foot thick foundation that begun last year, after which structural steel can finally begin to rise . . . . The center is currently on schedule to open in late 2017.

This is not the tower but the adjacent and architecturally integrated terminal. But completion of its excavation may facilitate excavation of the tower. I believe the plan is to complete both at about the same time in 2017.

At the tower site, they do appear to be moving some dirt:

Salesforce in talks to take chunk of Transbay Tower
J.K. Dineen
Reporter-San Francisco Business Times

Speculation is picking up that Salesforce is in deep negotiations to take about 300,000 square feet in the Transbay Tower at 415 Mission St.

A source familiar with the talks said that the cloud computing giant is looking at the space and that the two parties are working on a “letter of intent” document, although it is not yet complete. The source cautioned that the talks are in early stages and that many details need to be ironed out for the lease to be completed.

Salesforce is currently consolidating its downtown San Francisco offices into three buildings: 50 Fremont, Rincon Center, and 350 Mission St., which is currently under construction. By the end of 2015 Salesforce will occupy about 500,000 square feet at 50 Fremont, 400,000 square feet at 350 Mission St., and 236,000 square feet at Rincon Center.

The company is currently looking to sublease its space in three other buildings: One Market St., 123 Mission St., and One California St. The space Salesforce is giving up in those three buildings totals about 275,000 square feet . . . .

In a recent earnings call Boston Properties Chairman Mort Zuckerman said that the “subgrade work at Transbay is progressing and our marketing program is in full swing.”

“We are in active discussions with a number of tenants and could deliver the building in late ‘16 or early ‘17 based on that current schedule. But we have not made a decision yet to move forward on this structure out of the ground,” he said.
http://www.bizjournals.com/sanfranci...&ed=2014-03-04

It was also mentioned at the Boston Props conference call that they have $1B reserved for construction of the tower. One presumes if they sign a lease for 300,000 sq ft they would give the final "go ahead".

According to SSP they are pouring caissons:

To me that is just arbitrary. Good to see that construction work is in full swing.

181 Fremont was moved to the construction section here on SSC once caissons were being poured, so doesn't that mean this one should be moved to the under construction section too?

Those will be the deepest caissons in SF history (nearly 300 feet deep, if i remember right?). 181 Fremont held that record for a short time, with 263' caissons, but not anymore

265 ft.

This and 181 Fremont are only a block apart. I assume in both cases the caissons go to bedrock which should be at roughly the same depth for both.

Clark anticipates commencing construction activities at the site in mid-August with below-grade work. Transbay Tower will be founded on rock by way of cast-in-place foundations extending down approximately 265 feet . The initial phase of below-grade work includes excavation, shoring, and foundations necessary to support a three-level below-grade parking structure.
http://www.clarkconstruction.com/our...transbay-tower

As for construction, in this area it isn't up to me but I would prefer to wait until we get some indication from Boston Properties that they've given the go-ahead to the above ground portion of the building. As of now, they seem to have approved the foundation construction but no more . . . until they sign an anchor tenant. Rumors are rife (Google, Salesforce.com) and the deal could be struck any day now, but until it is, the tower above the foundations is on hold.

I must say that the facade mock-up is reassuring. Doubt they would have ordered the panels fabricated if they had any doubt about moving forward. Still, an announcement would seal the deal (since it hasn't been very long since they made the point that they had not yet given approval).
