The University of Nairobi (UoN) Towers

The UoN Towers is a twenty-five-storey building located in the heart of Nairobi city. Geotechnical investigations revealed that beneath the towers, from 11 to 22m, lay completely weathered rock. The initial designs called for piled foundations. However, we drilled piers at column locations, which resulted in the project tender sum cost plummeting from Kes 3.1 billion to 2.1 billion.
