THE ROLE OF DRY CONSTRUCTION IN ENSURING AFFORDABLE HOUSES IN NIGERIA

THE ROLE OF DRY CONSTRUCTION IN ENSURING AFFORDABLE HOUSES IN NIGERIA

CHAPTER ONEINTRODUCTION

1.1   BACKGROUND TO THE STUDY  

With Nigeria’s capital expenditure profile put at 24 percent of recurrent expenditure in 20 14, the falling price of crude oil, and a high cost of funds for execution of capital projects, the construction industry in Nigeria is obviously under pressure to evolve more time and cost-efficient system of construction to ensure affordable housing in Nigeria. The importance of housing in human history cannot be overemphasized. Housing is seen as one of the best indicators of a person’s standard of living and of his or her place in society (UNCHS, 1993). Housing and building conditions also reflect the living standards of society (Venkatarama, 2004). Thus, the importance of access to adequate and affordable housing took the front burner in the mid 20th century. Most Nigerian don’t have access to decent housing units due to the cost occasioned by the cost of building materials. This has led to various researches into the development of new and innovative dry construction techniques to enhance access to housing for all. The new construction technology which is based on dry construction systems that are manufactured from cement, quartz sand, cellulose, natural calcium, and water, is processed by autoclave (drying process under high pressure and temperature) for durability and dimensional stability. They are manufactured into boards. The boards which come in various sizes and thicknesses between 6mm and 20mm are manufactured under strict quality control and international standards. Describing the dry construction system as a modern building system that tends to translate the building process into an industrial process, Le (2014) said the system is a more versatile and faster construction method that allows up to 70 percent construction time saving possible when compared with the traditional wet construction using bricks and blocks. He added that whatever the design idea the Architect can conceive, the dry construction system can achieve, pointing out that various reference building projects using the boards now abound in Nigeria. This system, unlike the traditional brick and block method, requires minimum use of water. The system generates minimum construction waste and dry construction buildings have much better preserve room temperature and they are energy efficient. The use of timber associated with the traditional construction is avoided with dry construction, and the system impacts positively on reducing deforestation. Lower dry construction load impacts on minimum excavation, less soil disturbance. The system compliments better the green building idea for modern construction the world over. In addition, the system is a lightweight construction. It is about 10 times less in weight compared to equivalent blocks and mortar construction, resulting in savings in the foundation and structural costs. Dry construction for eave solution has also proved to be a much viable solution with lower self-weight, faster and better technical finishes. Dry construction building boards have a high fire-resistance rating and good acoustic and thermal properties. It is also a moisture and pest resistance solution. Explaining that skill-gap is a major challenge for dry construction, Le (2014) noted that some companies in Nigeria who are in partnership with other stakeholders with skills in dry construction technology to put in motion machinery for skill acquisition with regular training to ensure the technology is domicile with the Nigerian populace, adding that customers’ perception is another challenge to address, while efforts are in top gear towards continuous education about the modern system of the building.1.2   STATEMENT OF THE PROBLEM Various researchers are of the opinion that with the demand for housing in Nigeria growing at a geometric rate while housing provision is at an arithmetic rate, there is an obvious need to evolve a more practical method of achieving mass housing development in the country. Dry construction presents an excellent opportunity to the government at all levels and the primary mortgage institutions to guarantee the speedy provision of mass and affordable housing in Nigeria. The researcher is of the view that dry construction technology will provide building professionals and contractors a viable alternative to the traditional wet construction method with blocks and bricks and concrete. However, this study will examine the role of dry construction in ensuring affordable housing in Nigeria.1.3   OBJECTIVES OF THE STUDY The following are the objectives of this study:

To examine the role of dry construction in ensuring affordable houses in Nigeria. To examine the process involved in a dry construction system. To determine the factor limiting the use of dry construction system for building development in Nigeria.

1.4   RESEARCH QUESTIONS

What is the role of dry construction in ensuring affordable houses in Nigeria? What is the process involved in a dry construction system? What are the factors limiting the use of a dry construction system for building development in Nigeria?

1.5   HYPOTHESIS HO: Dry construction system cannot be used as a means for the provision of affordable houses for Nigerians. HA: Dry construction system can be used as a means for the provision of affordable houses for Nigerians.1.6   SIGNIFICANCE OF THE STUDY The following are the significance of this study:

The outcome of this study will educate professionals in building technology and other stakeholders in the building industry on the need for active innovative development with the use of dry construction systems with the view of ensuring the provision of affordable houses for Nigerians. 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 topic

1.7   SCOPE/LIMITATIONS OF THE STUDY This study on the role of dry construction in ensuring affordable houses in Nigeria will cover all the processes involved in the use of dry construction systems with a view of determining approaches that can be adopted in the delivery of sustainable mass housing for Nigerians.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 to the research work.

How To Write Chapter Three Of Your Research Project (Research Methodology)

  • Methodology In Research Paper


    Chapter three of the research project or the research methodology is another significant part of the research project writing. In developing the chapter three of the research project, you state the purpose of research, research method you wish to adopt, the instruments to be used, where you will collect your data, types of data collection, and how you collected it.

    This chapter explains the different methods to be used in the research project. Here you mention the procedures and strategies you will employ in the study such as research design, study design in research, research area (area of the study), the population of the study, etc. You also tell the reader your research design methods, why you chose a particular method, method of analysis, how you planned to analyze your data.

    Your methodology should be written in a simple language such that other researchers can follow the method and arrive at the same conclusion or findings.

    You can choose a survey design when you want to survey a particular location or behavior by administering instruments such as structured questionnaires, interviews, or experimental; if you intend manipulating some variables.

    The purpose of chapter three (research methodology) is to give an experienced investigator enough information to replicate the study. Some supervisors do not understand this and require students to write what is in effect, a textbook.

    A research design is used to structure the research and to show how all of the major parts of the research project, including the sample, measures, and methods of assignment, work together to address the central research questions in the study. The chapter three should begin with a paragraph reiterating the purpose of research. It is very important that before choosing design methods try and ask yourself the following questions: Will I generate enough information that will help me to solve the research problem by adopting this method?

    Method vs Methodology

    I think the most appropriate in methods versus methodology is to think in terms of their inter-connectedness and relationship between both. You should not beging thinking so much about research methods without thinking of developing a research methodology.

    Metodologia or methodology is the consideration of your research objectives and the most effective method and approach to meet those objectives. That is to say that methodology in research paper is the first step in planning a research project work.

    Design Methodology: Methodological Approach

    Example of methodology in research paper, you are attempting to identify the influence of personality on a road accident, you may wish to look at different personality types, you may also look at accident records from the FRSC, you may also wish to look at the personality of drivers that are accident victims, once you adopt this method, you are already doing a survey, and that becomes your metodologia or methodology.

    Your methodology should aim to provide you with the information to allow you to come to some conclusions about the personalities that are susceptible to a road accident or those personality types that are likely to have a road accident.

    The following subjects may or may not be in the order required by a particular institution of higher education, but all of the subjects constitute a defensible in metodologia or methodology chapter.
