NAIROBI — A multi-storey commercial building under construction collapsed near Kenya's capital on Friday, killing at least six workers and trapping an unconfirmed number beneath concrete slabs and mangled rebar.
The structure gave way without warning.
The collapse occurred in Mlolongo, a fast-growing commercial hub flanking the Nairobi-Mombasa highway, directly adjacent to the Standard Gauge Railway (SGR) Terminus. Emergency search teams immediately deployed heavy earth-moving equipment to rip through the pulverized debris. First responders from the Kenya Red Cross pulled at least three survivors alive from the rubble and rushed them to nearby hospitals with severe injuries.

|---|---|
| Location | Mlolongo, Nairobi-Mombasa Highway (near SGR Terminus) |
| Confirmed Fatalities | 6 dead |
| Survivors Rescued | 3 hospitalised |
| Site Type | Commercial multi-storey structure under construction |
| Lead Emergency Responder | Kenya Red Cross |
Friday's disaster marks the second mass-fatality structural failure in the capital region in less than a month.
On October 23, an uncompleted 12-storey tower collapsed in Nairobi, crushing eight people to death. Earlier in the year, on January 2, another multi-storey project under construction collapsed in Nairobi's South C neighborhood, pinning at least two workers under wreckage before emergency units cut them free.
Yet the warnings went unheeded.
Rapid urban expansion across Nairobi and its surrounding transit corridors has triggered aggressive commercial real estate development. But safety oversight has failed to match the pace of the pouring concrete.
State policy researchers have pointed to deep structural vulnerabilities in Kenya's construction sector.
According to documented assessments by the state-run Kenya Institute for Public Policy Research and Analysis, building collapses across the country stem from a lethal mix of substandard building materials, compromised structural blueprints, poor construction methodology, and absent site supervision. Rogue developers frequently cut corners on steel reinforcement, cement grading, and load-bearing calculations to pocket higher margins while bypassing municipal inspections.
Search and rescue personnel will work through the night to clear remaining slabs and determine whether additional labourers remain trapped in the foundation voids.
