Dam building at an impressively speedy pace won a recent world record in India, specifically for the most concrete poured in 24 hours. When completed in about a year, this project will provide drinking water to 20 million people and will generate 960 megawatts of power. Here’s some video, although the only words I understood were “concrete”, “project”, “non-stop”, “engineer” and “cubic meter”.
The Polavaram Project location:
[The] Polavaram Project entered into another Guinness Book of World Records on January 7 breaking [the] dubai record. The Navayuga Engineering Company Limited … completed 32,100 cubic metres of concrete work. The company … invited representatives of Guinness Record and also [the] international and national media [to the] Polavaram Project site and Navayuga [broke] the record [previously set by the] Three Gorges Dam in China.
Work on the project, being undertaken by the private sector Navayuga Engineering Co Ltd, is being conducted with extraordinary speed to make the dam ready for irrigation purposes by June.
“Concreting for a project of this size normally takes around three years, but at this pace and passion, the dam will be completed by June,” Navayuga MD Chinta Sridhar said.
A dam-building project in India broke a Guinness World Record by pouring 8,536,852 gallons of concrete in 24 hours.
… The Navayuga Engineering Company, which is building the dam, said the record was achieved by about 900 workers with the use of 20 agitator trucks and 70 transit mixers. The concrete came from 10 batching plants.
Andhra Pradesh Chief Minister Chandrababu Naidu said in accepting the Guinness certificate Monday that he expects the project to be completed by June 2019 …

Along with the wheel, the nail, the compass, the printing press, the internal combustion engine, the telephone, the lightbulb, penicillin, contraceptives, and the Internet, Live Science lists concrete as one of the top 10 greatest inventions that changed the world. The Hoover Dam site says this:
Concrete consists of four ingredients-sand and crushed rock aggregate, water and Portland cement. These must be mixed in the proper proportions to yield strong concrete. Aggregate is perhaps the most important of the materials in the concrete because it makes up as much as three quarters of the Dam’s mass. The aggregate must be clean and free of clays, salts and organic matter. A source of aggregate near the Dam was needed so that it would not have to be transported too far.
How many million gallons of concrete were used to make Hoover Dam?
Construction of the dam took 3.2 million cubic yards of concrete. The concrete was poured as 60-foot square interlocking blocks with 528 feet of 1 inch steel pipe running through the 215 concrete blocks.
Or… 3.25 Million cubic yards.
Three and one-quarter million cubic yards. – USBR
One cubic yard is about 202 gallons, and Apple’s Siri ( “What is Three point two million times 202?” Try it.) figures there were zero gallons of concrete used to make Hoover Dam.
Luckily, you can tap to edit.
So, assuming India is using imperial gallons in reporting the amount of concrete poured in just 24 hours, this record is roughly 1/8th the amount of concrete used to build Hoover Dam. It took about five years to build Hoover Dam.
The Polavaram dam project in India is expected to help a lot of people.
Navayuga undertook the project after the original contractor failed to adhere to the timelines.
“The project will solve the water problem of the north and south Andhra Pradesh with some 20 million people getting access to drinking water after its commissioning, and by 2020 year end, we will be able to generate 960 MW of power”, added Sridhar. …
The word Prolavaram means “king’s gift” and the area was named as a gift from Musunuri Prolaya, a hindu king according to an inscription in the area from the year 1330.
The gift of the dam is not without controversy, however, as you might imagine with any major change.
[The] project would submerge close to 600 habitations in Andhra Pradesh, Chhattisgarh, Odisha and Telangana, and also submerge about 8,000 acres of forest land and 500 acres of wildlife sanctuary.
There are always tradeoffs.
