After several buildings collapsed last year, President Uhuru Kenyatta ordered an audit.
The audit covered most parts of Eastlands, Dagoretti, Kasarani, Zimmerman, Roysambu, Githurai 44 and 45, Garden Estate, Thome, and Kilimani.
The report concluded that buildings collapse because of poor quality of concrete, lack of proper foundation and use of substandard building stones.
Here is a list of buildings that have collapsed in the recent past:
