The Balfour Beatty US California Division has successfully completed a concrete pour consisting of 8,218 cubic yards of concrete at the 42-story Transbay Block 9 residential tower project site at 500 Folsom St. in San Francisco. The amount of concrete poured is equivalent to 32 miles of a four-foot-wide sidewalk. The non-stop pour started at 1:59 a.m. on Saturday, June 17 and concluded at 1:56 a.m. on Sunday, June 18. The milestone marks the largest concrete pour on record for the company’s California vertical construction business unit.
Forty-five trucks, driven by 90 drivers on alternating schedules, delivered 888 truckloads of the concrete to five concrete pumps strategically located on the project site. The pour covered a 30,000-square-foot surface area to form the mat foundation situated 75 feet—or six floors—below the ground surface. Concrete thickness of the mat foundation ranged from 10 feet beneath the tower to five feet outside the tower. The mat is also comprised of 2.5 million pounds of reinforcing rebar.
minesweeper - a fantastic video. I've watched concrete pours in my neighborhood in real time. The fast video shows better how complicated the process is.

There has not been a photo of this construction site posted since October 2017 so I took a walk to see the progress. This is a building that will break the skyline in my view in a few months.
Having broken ground at the end of 2016, the 55-story tower and two podium buildings rising along Folsom Street, on Transbay Block 8 between Fremont and First, are now expected to be ready for occupancy in the second quarter of 2019.
IIRC they had to do some deep grouting (due to neighboring buildings) before they could start the excavation/shoring work. The basement is twice as deep and the shoring system is cutter soil mix wall and secant piles which takes longer to install then a soldier pile wall takes (what its neighbor has). It's at grade now though by the looks of it and should start to fly.
