258 trucks to deliver 11,500 yards of concrete in one monolithic pour that got started at five in the morning and finished by three in the afternoon.
Roughly that’s 258 trucks in 10 hours. 26 trucks per hour. Or if you like, 1 truck every 2 minutes 20 seconds.
The project is the San Diego, BAYSIDE condos ($795,000 to $12,000,000.each condo, 282 total.)
The photo shows the southern half (half!) of the ten-foot-thick RAFT slab, which will support the 35 story tower
