Description
Danish engineering company Semco Maritime A/S was in 2013Q3 awarded a design-build & turnkey contract for construction of a heavy fuel oil power plant to service the B2Gold mine located near the town of Tsumeb in the Otjikoto region in northern Namibia.

Aqvila subsequently won the design supply turnkey sub-contract for the civil works by Semco Maritime.

The power plant complex is built on a green field site close to the B2Gold mine and consists of a powerhouse building, back-up generator building, fuel treatment building and a workshop, welfare and service building, as well as structures for tank farms, stack, unloading areas and fire fighting equipment. 

Aqvila’s works included the detailed design of all reinforced concrete sub and superstructures, including 3D modelling of the structures and creation of bar-bending schedules as well as design, manufacture and supply of steel superstructure and cladding envelope for the various buildings. Furthermore, Aqvila supplied designs for internal roads, building services and underground utilities.

Focus on providing value-for-money for our client ensured the design of a light easily assembled steel superstructure, prefabricated in sections suitable for transport to the remote site in 40 foot containers, meaning that the steel buildings could be erected with a minimum use of heavy site equipment using bolted connection only. Furthermore, creative cladding solutions ensured a flexible design enabling site adaptations to be made to the cladding using a minimum of tools on site.
