What is the largest construction project in the world?

The Pyramid of Khufu, Egypt The Pyramid of Khufu was built during the reign of Khufu, the second pharaoh of the Fourth Dynasty of Egypt (c. 2670 BC), and is believed to have been built by Khufu as a mausoleum for himself. In ancient Egypt, every pharaoh began to build a mausoleum for himself from the day he ascended the throne, in order to transcend himself as a god after death. The 4 inclined planes of the Great Pyramid of Khufu are facing the east, south, west and north squares, the error does not exceed 3 points of the arc, the bottom edge is originally 230 meters long, due to the limestone falling off the outer layer of the tower, the bottom edge is now shortened to 227 meters, and the inclination angle is 51 degrees 52 minutes.

The original height of the tower, because the top is peeled off, is now high meters, equivalent to a 40-storey skyscraper, the bottom surface of the tower is square, covering an area of 10,000 square meters. The Pyramid of Khufu is made up of 2.3 million boulders of various sizes, each weighing between tons and 160 tons, with tight seams between the stones and no adhesive. If these stones were hewn into small pieces with an average of one cubic foot and arranged in rows, their length would be equivalent to 2 3 of the circumference of the earth.

The Pyramid of Khufu is a huge and elaborate structure, and its construction involved various fields such as surveying, astronomy, mechanics, physics and mathematics, and is called the greatest stone structure in human history, and there are still many unsolved mysteries.

The world's largest single construction project is the Three Gorges Water Conservancy Project.

When it comes to the Empire State Building in the United States, the early sky should be one of the representative projects in New York City, the United States, which is not only a very well-known office building in the United States, but also a famous tourist attraction in the United States.

The 80th floor of the Empire State Building is also very topical, the key is to describe the entire history of the Empire State Building, the design scheme and some of the whole process of construction, all the exhibitions we can observe the manuscripts of the engineering building, engineering construction, history, etc., the 80th floor can lead to the 86th floor, the 86th floor is also very topical, and you can watch the night view of all the big cities, which is really dazzling.
