Basically, how to built a dam?

Dams, frankly, are the one of the most huge construction buildings. They are generally used for keeping high-volume water i. e. the range of volume is approximately 5-300 million m3 and used for getting electrical energy to convey to the urban and rural electrical consume and delivering centers. It’s a clear fact that people started to employ and to consume the water ever since they emerged on the world. That situation makes the water valuable. Hence, they realized that the water needs to be keep and preserve for the long-term usages. The early civil engineers constructed the first prototypes of the dams in the early B. C 1000. Firstly, to build a dam, the water place for the dam needs to be decided whether it’s useful or not to build a dam by civil engineers are mostly works on water engineering. Because the engineers, with no doubt, would be sure the possible places for a dam such as rivers, valleys, canyons, mountains, and etc. requires the minimum costs of expenses of the construction. Second of all, they design a project of the dam. The installation of the dam costs over lots of million dollars even today. The materials of the dam construction mostly cover the high grade cement, strengthened concrete, in a various size of pipes, reinforcing bars, (if necessary) slurry trenches for the cores, binding materials, and the other main ones. After the project planning, the excavators start to dig the previously accurated places and accumulate the huge piles of the land. During the digging of the land, the trucks move away the earth mass in order to reproduce the new materials for using in the different construction projects.
