What Has the NCA Said About the Collapse?
The NCA said the immediate priority was protecting the public as a multi-agency team coordinated rescue operations and preliminary investigations at the scene.
The affected site was cordoned off, with members of the public urged to keep away from the area and other restricted zones to allow emergency responders to work safely.
The authority said further information on the rescue operation, the status of the site and actions being undertaken by the multi-agency team would be communicated in due course.
Investigations Underway
The collapse has renewed questions about construction safety, regulatory oversight and compliance with approved building plans in Nairobi.
Investigators will need to establish the circumstances surrounding the collapse, including whether the building complied with the applicable construction requirements and whether any failures contributed to the disaster.
The NCA’s announcement is an important step in identifying the parties officially listed on the project, but the cause of the collapse and any potential responsibility remain matters for investigation.
The National Construction Authority is a state corporation established under the National Construction Authority Act No. 41 of 2011, with a mandate to oversee and coordinate Kenya’s construction industry.
Investigations into the Eastleigh building collapse are ongoing.
