Quay wall in Durban, South Africa
Interbeton [the international group company of HBG] has been awarded the contract for the construction of a quay wall in Durban, South Africa. The project, in joint venture with South African construction companies Grinaker-LTA and BCW, is for the National Ports Authority. The contract value amounts to 33 million euros, of which HBG's share is more than 13 million euros.
The port of Durban is one of the biggest on the African continent. Two extra berths will facilitate the growing transfer of goods. The joint venture will build a quay wall with a length of 1,200 metres, to service ships with a maximum depth of 15 metres.
The project also includes the construction of a prefabrication yard for the production of 52 caissons. These prefabricated elements – 24x17x18 metres – will be built on land and lowered in the water by a synchro lift. The caissons will be towed to the construction site and submersed to a foundation bed. The new quay wall will be built 200 metres in front of an existing berth. In between, the joint venture will carry out landfill, for which three million cubic metres of sand is needed.
