A wharf is a device for loading and unloading passengers and goods at the edge of a body of water.

It is a levee usually covered with stones, at the edge of a harbor basin or on the banks of a river, a canal, a lake, and intended to hold the banks or facilitate the docking of ships for unloading.

In the case of this quay built by TERASCOM on behalf of ENI CONGO, we replaced the stone lifting by masonry works consisting of a retaining wall perpendicular to the water level and along a platform. form allowing docking and landing and boarding operations.

On a quay, there are lifting devices, such as cranes and gantry cranes, as well as constructions such as warehouses used for storage.
