Construction of a new 23-storey office building in the heart of the Lagos business district
Central Bank of Nigeria, Lagos Office
In the heart of Lagos’s busy financial center, Julius Berger was assigned to rebuild the Central Bank of Nigeria’s Lagos Office, comprising the demolition of the existing 11-story building and the construction of a new 23-story office building with basement.
The site location posed the greatest challenge to the project. The limited size of the site did not allow for an appropriate material and/or equipment yard on site, requiring Julius Berger to place its office yard and main material storage yard hundreds of meters away. The densely built and tightly neighboring premises, buildings and streets also made it difficult for piling works and for the movement of trucks and other equipment to maneuver towards the site and its surroundings.
Due to the high ground water level, comprehensive subsoil investigations were carried out. As a result, a special ground works design was implemented to ensure that ground water would not enter the building pit during the construction of the basement.
Floors 1 to 5 of the building have been designed as the building’s own car park whereas floors 6 to 19 form the main office floors consisting of the different Central Bank departments and facilities. On top of the 19th floor a circled 3-story penthouse office area with helipad was constructed. The whole building including the penthouse floors are “wrapped up” in an aluminium glass façade with natural stone elements. Together with the façade’s additional recesses and curved parts, the building reflects the highest architectural and technical standards within the financial district of Lagos Island.
