Fresh Audit of City Buildings Ahead of Mass Demolitions

The Nairobi Metropolitan Services is set to undertake a structural audit of private commercial and residential buildings ahead of the planned demolition exercise of over 600 condemned structures within the city.

The exercise, coming at a time when increased cases of collapsed buildings are being recorded in the country, will focus on the structural integrity and safety of buildings found within the county of Nairobi.

It will be spearheaded by the NMS Directorate of Lands, Housing and Urban Development.

According to the NMS, the audit will also involve “sensitisation and technical training of county government and national government staff on building audit and inspection to verify structural integrity and safety of buildings” across the county.

The State recently ordered the National Building Inspectorate (NBI) to demolish thousands of buildings that were declared unsafe for occupation in various parts of the country.

This follows a 2018 audit by the NBI, covering 14,895 buildings, which classified 723 structures as dangerous, 10,791 unsafe, and 1,217 fair – with 2,194 buildings declared safe.

Over 600 buildings, mainly in Eastlands, were found to be at a high risk of collapse.

Dangerous buildings

The audit identified Huruma as the estate with the most dangerous buildings – totalling 388. Other areas with dangerous houses include Thika Road (85), Pipeline (65), Babadogo (38), Umoja (18), Dagoretti (16), Nairobi West (9), and South B (5).

Structural weakness, uneven staircases, and poor ventilation due to improper erecting of the structures have been identified as the common defects in buildings in these areas.

Meanwhile, poor workmanship and lack of professional supervision have been identified as the chief causes of building collapse in Kenya, where two-thirds of buildings collapse after completion and a third during construction.

Eighty-seven cases of building collapses have occurred in the country over the past five years – claiming the lives of about 200 people and injuring more than 1,000 individuals.

Of these cases, 65% are residential buildings, 25% commercial buildings, and 10% are mixed-use developments, which shows developers of residential flats are more likely to hire unaccredited contractors in a bid to cut construction costs.
