Building collapse: SON calls for stricter regulation, increased collaboration to address construction failures
Maureen Aguta
The Director General and Chief Executive of the Standards Organisation of Nigeria (Standards Organisation of Nigeria (SON) has reiterated the need for a comprehensive approach to building collapses in Nigeria to prevent repeated incidents from occurring in the future and to ensure the safety and integrity of structures across the nation.
The Director General Dr. Ifeanyi Chukwunonso Okeke made this assertion in regards to the frequent spate of building collapse across the Country and the wanton destruction of lives and properties on each occurrence.
Dr. Okeke stated that compliance to Specifications and Codes of Practice in the Standards by regulators and service providers in the sector plays an important role in reinstating the eroding confidence of Nigerians in the Nigerian building industry.
He said following investigations carried out by the SON, the cause of incessant building collapse was attributed to poor structural designs, quackery and unprofessionalism and inadequate or lack of soil testing. Other causes include poor construction practices and procedures, unapproved construction, wrong demolition process, lack of maintenance, negligence, use of substandard materials (steel reinforcement bars) as well as poor drainage around the collapsed buildings.
Adding that samples of beams & columns and reinforcement steel bars collected from the various building collapse sites such as the Gerard Ikoyi, Garki, in the Federal Capital Territory Abuja, the St. Academy School in Jos, Plateau State, Obingwu, Ukwa Local Government in Abia State amongst several sites across the Country were all subjected to laboratory tests.
The SON Boss said analyses from the samples showed that the major causes of building collapse were mainly due to poor cement-to-sand mix ratio as well as deliberate failure to comply with established building codes.
The DG stated that the Organization on its part has produced 168 Standards and Codes of Practice for the building and construction industry since 2004 for contractors to implement during construction: These standards he outlined as: Nigerian Industrial Standard (NIS) 117: 2004 Specification for Steel Bars for the Reinforcement of Concrete, Nigerian Industrial Standard (NIS) 499: 2004 Standard for Iron and Steel, Nigerian Industrial Standard (NIS) 588: 2007 Testing Hardened Concrete Part 1: Method for Determination of the
Compressive Strength of Concrete Cores, Nigerian Industrial Standard (NIS) 585: 2007 Standard for Concrete Admixtures – Part 1 – Specification for Accelerating
Admixtures, Retarding Admixtures and Water Reducing Admixtures, Nigerian Industrial Standard (NIS) 156:1982 Standard Method for Testing Fresh Concrete and Nigerian Industrial Standard (NIS) ISO 41001:2020 Facility Management System Standard amongst others.
In addition, the SON Helm’s man said the Organization has established regulatory powers established in the SON Act to regulate locally manufactured products through its Mandatory Conformity Assessment Programe (MANCAP) and its pre-shipment verification of conformity to standards for imported goods through the Standards Organisation of Nigeria Conformity Assessment Programme (SONCAP). Other Initiatives include the Product Authentication Mark (PAM) which gives the Consumer the power to verify the authenticity of a product before purchase.
Other initiatives taken was the setting up of the SON’s task force Special Intervention to Standardize Steel Reinforcement Bars where stakeholders in the sector, were engaged and full-scale nationwide enforcement in factories and marketplaces was undertaken and as a result, culpable dealers were sanctioned in line with the provisions of the SON Act No.14 2015.
While assuring the public that the responsibility of attaining a safe environment through standardization and quality assurance is unending, he however assured of the Organization’s resolve to continue to collaborate with other sector regulators, including the Council for the Regulation of Engineering in Nigeria (COREN), Nigeria Building and Road Research Institute (NBRRI), Nigerian Institute of Quantity Surveyors (NIQS), Raw Materials, Research and Development Council (RMRDC), the Ministry of Works and other developments agencies at both the state and federal levels.
