how come i cant order concrete and pump today?
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.

the red, yellow, blue, and white of the trucks and pumps look nicely coordinated.
great photo.
but 11,500 yards in 258 trucks?
agree... excellent photo.
also agree about the number of trucks... i thought a typical truck carried about 10 cu. yds? am i mistaken?
i dont know, i coppied and pasted it.
i think 258 trucks going back and forward all day.
i think i count about 39 cement trucks right there in that one shot.
idle thought...does adding all that weight move that rail line any?
jstephen - you mean after they took out 18 feet of soil?
i did a very similar project about 10 years ago (8 foot thick mat supporting 30 story tower). in order to minimize traffic disruption, the city made the contractor start the pour in the evening after rush hour and they poured all through the night to finish before morning rush hour.
i spy with my little eye
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.
very nice.
