How come I cant order concrete and pump today?
(OP)
Picture I got from someone. It is Bayside condo foundation concrete pour in San Diego of the south one-half only of the ten-foot-thick RAFT slab, which supports the 35 story tower. This was a 258 truck-ballet in which the contractor placed 11,500 yards of concrete in one monolithic pour that got started at five in the morning and finished by three in the afternoon." 258 trucks in 10 hours = 26 trucks per hour = 1 truck every 2 minutes 20 seconds.

But 11,500 yards in 258 trucks?

Also agree about the number of trucks... I thought a typical truck carried about 10 cu. yds? Am I mistaken?

Idle thought...does adding all that weight move that rail line any?

43 trucks,
16 pumps (maybe 17 or 18 or just extra tube),
1 train
no Waldo
Looks like we could get those cranes up and at it for some bucket-placing.

It must have taken a number of plants and renting trucks from the competitive concrete suppliers. The main supplier cannot shut down other jobs just because of one job, so rentals are usually necessary. There were not too many spare pumpers, so that could have been a critcal equipment factor in addition to access.
Usually, you start pouring slow and ramp up the number of trucks as you go to maintain an even flow of concrete and minimize the waiting time. You cannot afford to overload the site early because you end up with a build-up of waiting time that you cannot dig out of. Each truck used hauled an average of only 44 yards, but I imagine some trucks got up to 60-70 or more yards if they hauled from a nearby plant.
Waldo was in the white truck in crosswalk.
