Three workers killed as a perimeter wall collapses at a Riverside excavation site in Nairobi, police say

Three workers were killed when a perimeter wall collapsed on Saturday morning at a construction site in Riverside, Nairobi, that was still at the excavation and foundation stage, Nairobi police boss Issa Mohamud said. The county government said 39 workers were recorded at the site; eleven were rescued alive with severe injuries and taken to hospital, fourteen were accounted for and confirmed safe, and rescue teams were still working to establish the whereabouts of the others. The collapse came a day after six workers died in a building collapse at Syokimau.

What happened

The wall gave way at about 11:30am on Saturday at a property undergoing excavation near Grand Residence in Riverside. Preliminary assessments said the main building was still at the excavation and foundation stage, with no upper floors erected.

Workers at the site began searching the rubble themselves alongside emergency teams, and the area was cordoned off as multi-agency rescue operations continued.

A perimeter wall collapsed on Saturday morning at an active construction site in Riverside, Nairobi, near Grand Residence; the site was at the excavation and foundation stage, with no upper floors built, the county government said.

Why this label: Both reports describe the same wall collapse at an excavation site on Saturday morning; Capital FM carried the first emergency reports.

On the ladder: a claim earns Verified from primary evidence, or from two independent sources that do not copy each other.

Verified
Nairobi police boss Issa Mohamud said three workers died in the collapse: 'We have three fatalities and others are injured. We want to know what happened and how.'

Why this label: The toll is the police boss's own on-record statement at the scene. Earlier reports from the scene had spoken of two people feared dead before any toll was confirmed.

Verified
The county government said 39 workers were recorded at the site when the wall gave way at about 11:30am; eleven workers were rescued alive and taken to hospital with severe injuries, and fourteen were accounted for and confirmed safe at the scene.

Why this label: The 11-injured figure is confirmed a second way: the Kenya Red Cross reported 11 injured people evacuated to hospital by EMS Kenya ambulances.

On the ladder: a claim earns Verified from primary evidence, or from two independent sources that do not copy each other.

Verified
Rescue operations were continuing, with teams still working to establish the whereabouts of the remaining workers on the site's records, County Chief Officer for Disaster Management Bramwell Simiyu said; hospital admission checks and an on-site accounting exercise were under way.

Why this label: On the county's own numbers — 39 recorded, 14 safe, 11 rescued injured and three dead — 11 workers were still unaccounted for in the report read; no later accounting was read.

On the ladder: a claim earns Verified from primary evidence, or from two independent sources that do not copy each other.

Verified
The Kenya Red Cross said its Action Teams were responding at the scene with two E-Plus ambulances, and Kileleshwa MCA Robert Alai criticised the county administration's oversight of construction sites and called for those responsible to be held to account.

Why this label: The Red Cross statement is quoted the same way in both reports; Alai's criticism is his position, carried as such.

On the ladder: a claim earns Verified from primary evidence, or from two independent sources that do not copy each other.

Verified
After the rescue, the County Department of Built Environment and Urban Planning, working with the National Construction Authority, will carry out a structural and regulatory compliance audit of the site, the county government said.

Why this label: The audit is the county's stated next step; no cause for the collapse has been given.

Why it matters

Two fatal collapses at Nairobi-area construction sites in two days — six dead at Syokimau on Friday, three at Riverside on Saturday — put the county's oversight of building sites under immediate scrutiny, and a county and National Construction Authority audit of the Riverside site has been promised once the rescue ends.

Background

  • A building under construction collapses at Syokimau, killing six workers; police say all 405 workers on that site were later accounted for.

  • A perimeter wall collapses at the Riverside excavation site in Nairobi; police say three workers were killed.
