Shoddy Nairobi buildings at high earthquake risk

At least three out of four buildings in Nairobi would be seriously damaged in the event of a major earthquake, a new report on the state of construction in the city says.

The report by Questworks, a design and engineering firm, says contractors who steal cement and use less steel are to blame for most of the weaknesses. Architects and engineers also add to the exposure by failing to verify the quality of the works.
