Was that even more than the twin tower pour for the foundation?

Not really sure...

350 Relocated During Concrete Job
From NST

KUALA LUMPUR: Some 350 residents of Suasana Loft and Suasana Sentral condominiums were temporarily relocated to two hotels in KL Sentral to facilitate accommodate a 36-hour-long concrete pouring by developer GSB Sentral Sdn Bhd.

GSB in a press statement said the residents were offered free accommodations at KL Hilton and Le Meridien last weekend to “ensure that the construction of the basement slab at 348 Sentral project is done safely and without causing disturbance during odd hours for the residents”.

Its spokesman said City Hall had issued permit and approval for GSB Sentral to perform the concrete pouring earlier in the month and that construction work permit was also extended from 6pm to 10pm on weekdays.

He said the weekend exercise was the first in a series of six sessions over the next two months.


“We wish to thank residents for their cooperation and understanding of the construction procedures. Overall, the work went well with no untoward incident during the 36-hour session.

“We will be distributing notices to the residents on the same exercise that will take place this weekend. Affected residents can check in for a night at the hotels from 2pm on Saturday,” he said, adding that the company is paying for the hotel stay.

A Suasana Sentral resident Anand Mudunuru said: “We appreciate GSB Sentral’s concern in ensuring that our needs are taken care of and not having to hear loud noises during weekend and at the same time still able to spend good times with our families at the five-star hotel.”

it wasnt. twin towers still holding the record for the biggest single pour, about 13000m3. not easy to pass the record since the petronas pour was not separated into multiple casting zones, unlike here sentral project. logistic, material and workability space constraint are the key reasons for them to cast the foundation in various stages.

Thank you so much for the info james.By the way if i should want to pour 1 cubic meter of concrete on a flat surface at 4 inches thick what would be the length and width?

fortunately, you didnt ask a tough math question or otherwise, the old days i had gone thru will haunt me down.

to answer that, you can always use the basic volume formula; volume = length x width x thickness. by assuming the area of pour is square area, 1m3 of concrete volume is divided by 0.1m thickness and the result is square rooted to get an equal dimension of length and width. that is, you would get the answer at approx 3.2m (length) and 3.2m (width).

but in construction world, the volume derived from the estimation must add up site losses from the site wastage (ie flowtests, spillout, formwork workmanship and concrete uneven surface levels), and secondly the delivery inefficiency (ie wet and dry weather can influence the concrete mix proportion due to sand dampness, and the wastage from truck mixer after unloading). in practice, concrete volume in estimation and actual use differs by 5 to 10% margin in accuracy range. it takes lot of experience and observation to carefully estimate the volume during the tendering exercise or else, all the profit margins anticipated will dried up faster than the concrete does.

whats make you feel that achieving >5000m3 pour within 36 hours is impossible task? logically, you wont be so silly to depend on one concrete pump to do the mammoth job and risk severe concrete cold joint. you would probably require at least 5 pumps to operate at 30m3/per hour/per pump to achieve. thats of course, a theoritical plan only, which has not included the delivery breakdown, site problems, etc which could drag the casting duration to far longer period.

the 5500m3 record is not the biggest. there were some previous sites like menara maybank which had achieved >5000m3 in single pour. petronas pour is approximately at 13,200m3 per tower.
