Abstract
Residential building collapses in Nigeria have become a major concern due to the frequency of such incidents and the devastating effects they have on human lives, properties, and the economy. This research project aims to investigate the causes, effects, and possible solutions to the issue of residential building collapse in Nigeria. The study employs a mixed-methods approach, combining qualitative and quantitative data collection methods to gather comprehensive and reliable information. Data will be gathered through a review of existing literature on building collapses in Nigeria, interviews with key stakeholders such as architects, engineers, government officials, and residents of affected areas, as well as on-site inspections of collapsed buildings. The research findings indicate that the primary causes of residential building collapses in Nigeria include poor construction practices, the use of substandard materials, lack of adherence to building codes and regulations, inadequate supervision by relevant authorities, and corruption in the construction industry. These factors contribute to structural weaknesses and compromise the integrity of buildings, leading to their eventual collapse. The effects of residential building collapses are far-reaching, encompassing loss of lives, injuries, displacement of families, psychological trauma, economic losses, and damage to infrastructure. These incidents also erode public trust in the safety and reliability of buildings in Nigeria, hindering investment in the real estate sector and impeding economic growth. To address the issue of residential building collapse in Nigeria, this study recommends a multi-faceted approach involving the government, regulatory agencies, construction professionals, and the general public. Key solutions include strict enforcement of building codes and regulations, regular inspection of construction sites, training and certification of construction workers, public awareness campaigns on building safety, and sanctions for non-compliance with construction standards. By implementing these recommendations, stakeholders can work together to prevent future residential building collapses and ensure the safety and well-being of Nigerian citizens. This research contributes to the body of knowledge on building collapses in Nigeria and provides valuable insights for policymakers, professionals, and the public to address this critical issue effectively.

Thesis Overview

INTRODUCTION1.1 BACKGROUND TO THE STUDYSince independence, the Nigeria government has desperately continued to make concerted effort in the area of quantitative (but not qualitative) supply of mass housing through huge budgetary and policy provisions but, surprisingly, the rate at which existing ones are collapsing calls for an urgent attention. The site of building collapse scattered across the length and breadth of Nigeria is quite alarming that it is unimaginable what effects it will have on the building industry and Nigeria economy as a whole. One could imagine what edifices these buildings would have been if only they were constructed accordingly. It has been reported that Nigeria, especially Lagos State has become the -world’s junk-yard” of collapsed buildings worth billions of naira (Famoroti, 2005). It is quite unimaginable that a county blessed with so great potentials in its construction industry can experience such magnitude of building collapse Fadamiro in 2002 defined building as -an enclosure for spaces designed for specific use, meant to control local climate, distribute services and evacuate waste”. Buildings can be defined as structural entities capable of securing self by transmitting weights to the ground. More so, buildings are defined -as structures for human activities, which must be safe for the occupants”(Odulami, 2002). However, these same buildings have been posing treats and dangers to people either during or after construction as a result of its collapse. Collapse as a whole occurs when part or whole body of a structure fails and suddenly gives way, the structure, as a result of this failure, could not meet the purpose for which it was meant for. Building collapse is an extreme case of building failure. It means the super-structure crashes down totally or partially (Arilesere, 2002). Building failure occurs when there is a defect in one or more elements of the building caused by inability of the material making up the components of such building elements to perform its original function effectively, which may finally lead to building collapse. Buildings are meant to provide conveniences and shelter to the people, but the same building has been a danger trap to the same people. Building is expected to meet certain basic requirements such as buildability, design performance, cost effectiveness, quality, safety and timely completion (Olusola, Atta & Ayangade, 2002). Generally, buildings are expected to be elegant and functional but many projects are constructed that do not meet any of these basic requirements. The recurring incidence of building collapse, some of which claimed innocent lives is a consequence of this. Many studies has been carried out and various workshops organized in major cities of the country by various bodies, government agencies and institution in order to look into causes of the incidence of building collapse in Nigeria, but none has been able to come out with how each of the determined factors directly lead to building collapse in the country. There are many factors that cause building collapse in Nigeria and they are structural design and quality management according to Olusola (2002).The quality management entails material variability, testing variability, judgment factor, contractors’ variability, poorly skilled workmen and unprofessional conduct. The study aimed at examining the cases of residential building collapse in Nigeria with a view of identifying the causes, effect and solution.1.2 STATEMENT OF THE PROBLEMBuilding collapse is a defect or imperfection, deficiency or fault in a building element or component. It may also be as a result of omission of performance. The degree of building collapse can therefore be related to the extent or degree of deviation of a building from the -as - built” state which is in most cases represent the acceptable standard within the neighborhood, locality, state or country. (Ikpo, 1998). However, building collapse can simply be defined as a total or partial/progressive failure of one or more components of a building leading to the inability of the building to perform its principal function of comfort, satisfaction, safety and stability. The incessant buildings collapse in Nigeria has become a great concern to all the stakeholders - the professionals in building industry, government, private developers, clients and users, as well as the neighborhood residents. Fall out of the researcher’s concern about the increasing incidents of collapse building nation-wide form the basis for this study to find out the major causes, effects and probable remedial measures to collapse of buildings in Nigeria.1.3 OBJECTIVES OF THE STUDYThe following are the objectives of this study:1. To examine the causes of building collapse in Nigeria.2. To identify the effects of building collapse in Nigeria.3. To identify the remedial measures or approaches to building collapse in Nigeria1.4 RESEARCH QUESTIONS1. What are the causes of building collapse in Nigeria?2. What are the effects of building collapse in Nigeria?3. What are the remedial measures or approaches to building collapse in Nigeria?1.6 SIGNIFICANCE OF THE STUDYThe following are the significance of this study:1. The outcome of this study will educate the general public and the government of the day on the causes, effect and solutions to the cases of building collapse in Nigeria.2. This research will also serve as a resource base to other scholars and researchers interested in carrying out further research in this field subsequently, if applied will go to an extent to provide new explanation to the topic1.7 SCOPE/LIMITATIONS OF THE STUDYThis study on residential building collapse in Nigeria with careful examination of the causes and the effects with a view of finding a lasting solution to the issue of incessant building collapse in Nigeria.LIMITATION OF STUDYFinancial constraint- Insufficient fund tends to impede the efficiency of the researcher in sourcing for the relevant materials, literature or information and in the process of data collection (internet, questionnaire and interview). Time constraint- The researcher will simultaneously engage in this study with other academic work. This consequently will cut down on the time devoted for the research work.
