A dock building apparatus comprises a cantilever arm () having a first portion configured to be supported on a ground area and a second portion for overhanging a construction area. The cantilever arm () is displaceable perpendicularly to the length of the cantilever arm. The apparatus further includes a lifting device () movable along the cantilever arm for bringing construction materials including foundation members from the ground area to the second portion of the cantilever arm, and a foundation building tool () movable along the cantilever arm for installing the foundation members in the construction area.

Dock building apparatus and method of construction using the same

A method for building a bridge, said bridge comprising piers and at least one deck. The method including a cantilever step, wherein a girder is set in a cantilevered position relative to a bank or to a constructed zone of the bridge so that the girder comprises a first end overhanging the bank or the constructed zone, and a second end overhanging a construction zone of the bridge, and a construction step, wherein pier elements and deck elements are installed in said construction zone via a first and a second lifting devices mounted movable on the girder between the first and second ends. The first and second lifting devices cross one another along the girder during the cantilever step and/or during the construction step.
