posted a drone video of the mat pour on LinkedIn. I tried to see if they posted it to a less shitty video host like Youtube or even Twitter, but didn't see anything.

Yesterday, 250 concrete trucks delivered 9 million pounds of foundation to form the foundation for Phase One of 400 Lake Shore, Related Midwest's 72-story residential tower that will reshape the city's skyline where the Chicago River meets Lake Michigan. Led by LR Contracting Company and BOWA Construction teams, the concrete pour for the mat foundation of the building averaged a delivery every 2 minutes for 12 hours straight with 470,000 gallons of concrete, the equivalent to a 9-mile long sidewalk.
