Building Collapse Risks: Lagos Seals 827 Construction Sites

Lagos State Government has sealed 827 construction sites across the state in the last 12 months as part of intensified enforcement measures aimed at tackling building collapses and ensuring compliance with construction safety standards.

The government said the enforcement drive forms part of a broader strategy to stem the persistent challenge of building failures, particularly in informal settlements and unapproved developments where many developers operate outside established quality control procedures.

General Manager of the Lagos State Materials Testing Laboratory (LSMTL), Engr. Olayinka Abdul, disclosed this while answering questions at the 2026 Ministerial Press Briefing held at the Bagauda Kaltho Press Centre, Alausa, Ikeja.

Abdul said the agency had moved beyond conventional testing methods and adopted a proactive, intelligence-driven quality assurance system designed to detect violations before they result in structural failures.

According to her, the agency issued 3,181 notices to property owners and developers during the review period, while enforcement teams carried out 822 compliance operations across construction sites statewide.

She disclosed that 439 sites were sealed following non-compliance with regulatory directives, while hundreds of others were shut down over violations linked to destructive and non-destructive testing requirements, bringing the total number of sealed facilities to 827 within one year.

“These sealings are not just statistics; they send a clear message that no structure is too big and no developer too connected to escape quality control measures in Lagos State,” Abdul said.

The LSMTL boss attributed many building collapse incidents to developments in informal settlements where developers often evade statutory testing procedures and regulatory oversight.

To address the challenge, she said the agency has introduced sweeping reforms anchored on technology, stricter enforcement and industry-wide compliance monitoring.

Among the reforms, she said, was the introduction of the electronic Materials Testing Management System (e-MTMS), a digital platform that assigns unique tracking codes to every construction sample submitted for testing, thereby eliminating human interference and reducing opportunities for result manipulation.

Abdul said the agency has also enforced a mandatory three-stage testing regime requiring developers to conduct tests at foundation, structural frame and roofing stages before construction can proceed.

She added that all registered construction sites are now geotagged and mapped using GPS technology, enabling enforcement teams to verify compliance remotely and monitor projects in real time.

“The agency has also introduced a private laboratory accreditation programme under which only laboratories that pass bi-annual proficiency assessments are authorised to issue test certificates recognised by the Lagos State Government,” she disclosed.

In a further push to strengthen oversight, Abdul disclosed that a dedicated whistleblower and rapid response system had been established to enable residents report suspicious construction activities.

According to her, the agency responded to such reports within 48 hours and took immediate enforcement action where necessary.

The General Manager said LSMTL had also partnered with professional bodies, including the Nigerian Society of Engineers, the Nigerian Institution of Structural Engineers, the Nigerian Institute of Building and the Association of Real Estate Developers of Lagos, to implement compulsory training and certification programmes for key construction stakeholders.

She revealed that the agency conducted 7,077 steel destructive tests, 5,959 concrete tests, 1,818 water tests, 333 pile integrity tests, 948 steel stanchion tests and 226 geotechnical tests involving construction materials such as sand, granite and cement during the review period.

Abdul urged Lagos residents to demand valid test certificates before occupying newly completed buildings, stressing that preventing building collapse requires collective vigilance from regulators, developers and the public.

“We are working towards zero building collapse in Lagos, but residents also have a role to play by insisting on quality assurance and compliance before moving into any building,” she said.
