8. The method as claimed in claim 1 , further comprising the step of adjusting the yard leveling base after the step of placing a packed column section of a column onto the top surface of the yard leveling base.
9. The method as claimed in claim 8 , wherein a plumb line system is used to measure the levelness of the yard leveling base during the step of adjusting the yard leveling base after the step of placing a packed column section of a column onto the top surface of the yard leveling base.
10. The method as claimed in claim 1 , wherein adjusting the yard leveling base further comprises the step of putting a shim underneath the yard leveling base after the lifting system has caused the top surface to raise.
11. The method as claimed in claim 10 , further comprising the step of removing the lifting system from the notch after the shim is in place underneath the yard leveling base.
12. The method as claimed in claim 1 , wherein the packed column section has a diameter of at least 5 meters.
13. The method as claimed in claim 1 , wherein the lifting system is selected from the group consisting of a hydraulic lift, a screw lift, an air lift, and combinations thereof.
14. The method as claimed in claim 1 , wherein the top surface and the bottom surface maintain being parallel with each other during the step of adjusting the yard leveling base.
15. The method as claimed in claim 1 , wherein the yard leveling base comprises an annular shape, such that the yard leveling base has an inner diameter and an outer diameter, and the top surface and the bottom surface are parallel with each other, wherein the top surface is defined as the area between the inner diameter and the outer diameter.
16. The method as claimed in claim 1 , wherein the yard leveling base comprises a nut shape, and wherein the top surface and the bottom surface are configured to maintain being parallel with each other when the lifting system acts on the notch.
17. The method as claimed in claim 1 , wherein the yard leveling base comprises an inner diameter, an outer diameter, and a height.
18. The method as claimed in claim 1 , wherein the step of installing the yard leveling base on the ground of the remote manufacturing yard further comprises securing the yard leveling base to the ground.
19. The method as claimed in claim 18 , wherein the yard leveling base is secured to the ground using a clamp system.
20. The method as claimed in claim 1 , wherein the yard leveling base is configured to accommodate a weight of 100 metric tons.
21. The method as claimed in claim 1 , wherein the step of inserting the lifting system into the notch further comprises the step of inserting the lifting system in a direction that is orthogonal to the force of gravity.
