After the construction enters the site, first level the site, and use a digging machine to remove roots, soil, weeds, etc. Prepare electrical connection for construction water. <br> <br>Before setting up the plastic board, use a level gauge to measure the elevation on the ground according to a 20m × 20m grid, the surface elevation allows a construction deviation of ± 50mm, and report the data to the owner and supervision engineer for acceptance.

After the construction site, first to the site to be leveled, with the excavator to dig to remove the root soil, weedres and so on. Prepare the construction of water and electricity interface.<br> <br>Before the plastic plate is set up, the elevation of the ground according to 20m x 20m grid grid is measured with the level meter, the face scale height allows the construction deviation of 50mm, and the information is reported to the owner, the supervising engineer for acceptance.

After entering the construction site, the site shall be leveled first, and the root soil, weeds, reeds, etc. shall be removed by excavator. Prepare construction water and electricity interface.<br>Before setting up the plastic plate, use the level to measure the elevation of the ground according to the grid of 20 m × 20 m, the allowable construction deviation of the surface elevation is ± 50 mm, and report the data to the owner and the supervising engineer for acceptance.<br>
