The Institution of Engineers of Kenya (IEK) has called for a comprehensive technical investigation into structural defects reported at Karibu Homes in Athi River, Machakos County.
In a public statement, IEK President Eng. Harrison Kiplimo Keter, said the institution had taken a keen interest in reports of structural defects at the development.
Following a site visit, IEK engineers observed structural cracks in Blocks M, N and P within London Court. The development comprises 500 residential units in 63 apartment blocks, with some residents of affected units having vacated their homes over safety concerns.
IEK said the cracks, first noticed in 2019, have continued to widen and may indicate differential settlement, where sections of a foundation sink unevenly. Engineers also observed poorly constructed stormwater drainage systems around some affected buildings, with roof downpipes discharging close to foundations. Damp-related deterioration was also found at the base of some external walls.
However, IEK stressed that these are preliminary findings from a visual inspection and that it has not drawn conclusions on the causes of the defects.
The institution has recommended destructive and non-destructive structural testing, alongside a comprehensive geotechnical investigation to assess the foundations and guide repair and strengthening works. It has also advised that Blocks M, N and P remain vacant until the necessary works are safely completed.
IEK urged greater accountability and stronger enforcement of building regulations, stressing the importance of qualified professionals in the design, construction, inspection and completion of buildings.
