Method for the construction of a civil engineering structure and associated system

A method for the construction of a civil engineering structure comprising n superimposed components, where n>2, the method comprising the following steps for superimposing components:

• fixing a lifting structure comprising lifting means,
• moving horizontally a second component to a position below the fixed lifting structure,
• lifting the second component to a predetermined height using the lifting means,
• positioning a first component beneath the fixed lifting structure substantially below the second component, while the second component remains substantially at said predetermined height, and
• placing the second component substantially on the first component using the lifting means, the method further comprising the following steps, repeated for a number p ranging from 2 to n−1, wherein a group of p components comprises the previously superimposed components of the civil engineering structure;
• moving the group of p components away from the fixed lifting structure using movement means,
• positioning a p+1th component beneath the fixed lifting structure,
• lifting the p+1th component using the lifting means,
• positioning the group of p components beneath the fixed lifting structure substantially below the p+1th component, and
• placing the p+1th component substantially on the group of p components using the lifting means.
