A construction sand project in Bihar has come to an end after being delayed for a year.
The project, the first of its kind in India, had been expected to cost around $3 billion.
But the company behind it, Arup, has been forced to cut costs by $3 million per acre.
In the past, the project has faced a number of problems.
The government of Bihar, which is in the process of building a new metro network, has said it will need more than 400 billion cubic metres of sand.
It is unclear whether that amount of sand will be enough to support the project.
Arup said that it was also working on more than 4,000 other projects across the country.
But this latest project will be the biggest project to date in India’s capital, with a capacity of 4 million sq km (1.6 million sq miles).
The sand is being made from a combination of sand and rock, and the sand is also being processed in India.
But for now, the government of India has not said when the project will start or when it will finish.
It’s a huge achievement, said Amit Chaudhary, a professor of earth sciences at Columbia University in New York.
“I’m sure the project is a huge step forward in terms of building more resilient urban systems, and I’m confident that it will contribute to the world’s growing need for sand.”
