I hope the sandworm tower eats a few NIMBYs

When I compare the speed with which they are building this tower to others in the US, it seems to be 30 to 40% faster with maybe the exemption of Wilshire Grand in LA. Is there an expert on this forum who can explain why?

I have to laugh - it wasn't like 6 months ago that everyone complained how slow this building was going up.

Less than 6 months ago--more like 3 or 4 months. And as I explained then--several times--this building is like an iceberg. It extends 300 ft underground just as it will rise 1070 ft above ground. In addition to multiple basement levels and a massively thick reinforced concrete pad, it has reinforced concrete piers poured (not driven) down to bedrock 300 ft below. As is usual for exceptionally tall buildings in SF, roughly half the construction time was EXPECTED to be spent on the work below ground level, but we are past that now. In terms of time, the construction is about ¾ complete (2013 - 2017).

Not if you start from when construction began (2013) and take into consideration the below ground work (see above). Above ground it is rising rapidly because the design seems to be a massive concrete core with the rest of the building relatively lightly constructed and suspended from the core. And the forms for the core are movable--pour 2 floors, raise the forms, pour the next 2. What I am looking for is whether the core rebar is pre-fabricated to any degree. It seems that would be fairly easy to do since since each floor is like the ones above and below.

How many underground parking floor will there be, and, roughly, how many cars will they be able to take?

Not to ask dumb questions, but it can be harder to find this info even if it already exists among the tens or hundreds of pages, and I have it set to 40 posts per page.

Not so hard: 3 garage levels:

I'm not sure how many parking spaces there will be but I expect it's remarkably few. San Francisco does not encourage parking in either residential or commercial structures these days, especially when they are located somewhere as transit dense as this will be. And the floor plate square footage is not large so 3 parking levels really won't have room for a tremendous number of cars.

Personally, I'm more interested in what's going to be behind the rooftop screen (if anything). The original design specs called for wind turbines but I believe that's been abandoned.

They appear to be working on the rebar for the 20th floor of the core and the 15th floor steel framing today.

Thank you for this explanation!

When you work in the Salesforce tower and live in the new Fremont tower across the street, you don't need a car

I believe the forms are for one floor at a time. Each time the forms are raised, they are raised one floor at a time. Early on, you could see the concrete being distributed (from inside the forms) in sync with the inner and outer forms movement.

Actually, in that case you could walk to work through the terminal rooftop park and never have to go down to street level since both towers will have a bridge to the park.

Meanwhile, Salesforce posted something like 30% year over year revenue growth for this quarter today and Wall Street is cheering tonight with the stock up something like 8%. Wonder how much that represents to mark Benioff's net worth.

Salesforce now has a nice "campus" owning one and leasing 2 other buildings (including this one) on the 4 corners of the Mission/Fremont intersection. Benioff said that's what his employees wanted--to be "downtown" rather than in Mission Bay where the company had bought land intending to build a campus.

And one more thing (as Steve jobs used to say): I walked down to the site today and was awed by how dense it now feels. The 1st/Mission intersection is more than New York dense (I say "more" because I think the streets are narrower than New York's avenues and you feel more overwhelmed by the building canyon). Assuming the Oceanwide Center gets built on the remaining corner of 1st/Mission, it will be a remarkable place for urbanophiles.
