Technical Experts Audit 12 Lagos Materials Testing Laboratories to Curb Building Collapses

‎

‎LAGOS, NIGERIA — Technical experts from the Council for the Regulation of Engineering in Nigeria (COREN) and the Building Collapse Prevention Guild (BCPG) have partnered with the Lagos State Materials Testing Laboratory (LSMTL) to conduct a comprehensive joint inspection of 12 accredited materials testing laboratories across Lagos State.

‎The regulatory audit was initiated to strengthen quality assurance within the construction sector, verify the accuracy of equipment, and ensure strict compliance with engineering standards to prevent structural failures and building collapses.

‎Scope of the Assessment

‎During the joint inspection, the multi-agency delegation audited the operational capacity and technical integrity of both state and privately owned testing facilities. Key areas assessed included:

‎Equipment Functionality & Calibration: Verifying that machinery used for concrete compression, steel rebar tensile testing, and soil analysis undergoes regular calibration to maintain precision.

‎Personnel Competence & Certification: Confirming that laboratory analysts, field technicians, and supervising engineers hold required academic credentials and professional certifications.

‎Quality & Chain of Custody Documentation: Reviewing sample tracking procedures to ensure test results cannot be altered or falsified.

‎Standard Operating Compliance: Auditing testing protocols against the Nigerian Industrial Standards (NIS) and international civil engineering benchmarks.

‎Key Statements and Regulatory Responses

‎Lagos State Materials Testing Laboratory (LSMTL)

‎The General Manager of the LSMTL, Mrs. Olayinka Abdul, stated that the joint inspection initiative forms a central part of the state’s strategy to enforce quality control at the foundational level. She emphasized that rigorous material testing before and during construction is essential to protecting lives and restoring public confidence in the built environment.

‎Council for the Regulation of Engineering in Nigeria (COREN)

‎The COREN inspection delegation—comprising Engr. Olayinka Alli, Dr. Mojirade Oloruntoba, and Engr. Tomide Akinnawo—highlighted that technical professionalism in material evaluation is non-negotiable. The delegation noted that accurate testing and honest certification remain the bedrock of infrastructure durability across the state.

‎Building Collapse Prevention Guild (BCPG)

‎Representing the BCPG, Prof. Ewaen Ikponmwosa, former Head of the Department of Civil Engineering at the University of Lagos (UNILAG), stressed the necessity of routine, independent audits. He noted that privately operated laboratories require continuous oversight to guard against equipment drift and ensure that commercial interests do not compromise testing accuracy.

‎Geotechnical Sector Oversight

‎Highlighting the critical role of foundation safety, Engr. Ebenezer Ologuntoye, immediate past Chairman of the Nigerian Institution of Geotechnical Engineers (NIGE) Lagos Chapter, commended the exercise. He noted that because subsoil investigation reports are mandatory for securing building plan approvals in Lagos State, enforcing strict standards across geotechnical testing centers directly prevents foundational failures.

‎Regulatory Impact

‎The joint audit signals an intensified regulatory posture by Lagos State authorities and engineering bodies to eliminate substandard materials from construction supply chains. By establishing mandatory calibration checks, credential verification, and unannounced facility audits, regulators aim to ensure that all structural materials used in commercial and residential developments meet legal safety standards.

Key Categories of Accredited Testing Facilities in Lagos

The 12 audited facilities represent accredited laboratories operating across Lagos State that handle major quality assurance testing categories:

🪵 Concrete & Aggregates Testing Labs: Specializing in cube compression tests, rebound hammer assessments, and water-to-cement ratio verification.

🪵 Geotechnical & Soil Testing Labs: Responsible for boreholes, soil compaction tests, shear strength, and foundation load-bearing capacity evaluations required for building plan approvals.

🪵 Steel & Rebar Testing Centers: Conducting tensile strength, yield stress, and elongation testing on reinforcement bars.

🪵 Non-Destructive Testing (NDT) & Pile Integrity Labs: Evaluating already-erected structures, ultrasonic pulse velocity, and deep foundation pile continuity without destroying structural components (e.g., registered entities like MTT Innovations Ltd).
