Comparative Assessment of Factors Affecting Cost of Industrialized Building and Conventional Building System in Nigeria
CHAPTER ONE
Aim and Objective
Aim
This research aims at assessing the factors affecting the cost of industrialized building and conventional building system and to identify ways in which these factors can be controlled.
Objectives
- To identify the factors affecting cost of industrialized building and conventional building system in Nigeria.
- To evaluate factors affecting the cost of industrialized building and conventional building system in Nigeria.
- To establish the most important factors affecting cost of industrialized building and conventional building system in Nigeria.
CHAPTER TWO
LITERATURE REVIEW
Introduction.
The Nigerian construction industry is undergoing transitional change from a project base industry to a more systematic and mechanized product based technology. Construction method can increase productivity and quality of work through the use of systematic machinery, equipment, materials and extensive pre-project planning. However, cost impact appears to be major hindrance in preventing the contractor to use industrialized building system. As such, good cost comparison data and a holistic and thorough valued based on comparative system is required by the industry to ascertain the true benefits of industrialized building system and conventional building system for the particular project settings to support decision making in opting industrialized building system over the conventional system.
The objectives of this study are to propose a comparative cost study of industrialized building and conventional building system.
According to Barber (2000) industrialized Building system (IBS) is a construction technological advancement that produced the construction material which is assembled on site. It is a very systematic system that can change the current scenario and problems occurred in local construction
industry. The prefabricated components were fabricated at factory and then will be delivered to the site.
At the beginning process, the production of the component may involve planning; managing and maintaining quality to reduce waste (material and cost) and to ensure the component has no defect and can be delivered on time.
Industrialized building system can reduce unskilled labour, provide a safe environment on site, shorten the time period of construction process, ensure the quality of the structural works, and saving cost.
CHAPTER THREE
RESEARCH METHOD
PROCEDURE FOR DATA COLLECTION.
The data require for this research was obtained through the use of structural questionnaire, site visit, direct physical observations, textbooks and journals. An oral interview was also conducted with contractors, consultants, craftsmen, market surveying, specialist contractors and building components manufacturer.
The questionnaire (see appendix B)was designed in a simple format taking into consideration the background information about the industrial building and conventional building system project carried out in which respondents had participated in any form concerning cost related factors which may or can affect the construction cost of the system.

DATA PRESENTATION, ANALYSIS AND DISCUSSION
INTRODUCTION
This chapter considers presentation and analysis of the data collected during the course of the research work. The chapter also discusses the result obtained.
CHAPTER FIVE
Conclusion
Based on the theoretical views and the analysis carried out during the research, a major advantage of industrialized building over traditional building is that the building can be erected within a short period of time due to the use of prefabricated components and mechanical plant. The use of the industrialized building system offers relief from materials wastage, weather disruption, lost time due to breaks and discontinuity which are common with traditional method and good gusty products are obtained by the clients.
The concentration of heavy mechanical plants and the high level of technology needed by the system are found to be responsible for the high cost of the system. More so, the building industry does not give the appropriate tendering procedure and the government on their own part did not give the required economic and the government environmental needed by the system.
RECOMMENDATIONS
In order to achieve a viable efficient and economics building industry system in Nigeria, the following recommendation need to be achieved;
- Government should contribute in sowing the storage of funds for manufacturing facilities by granting interest free loan to prospective investor who are willing to invest in building industry and investors should be allowed to repay such loan within the period given to them by the government. This is done to enhance the supply of the components/traditional building materials.
- Government should help to reduce the cost of building components, materials, plants and equipment normally use to execute the building works. These can relief the contractor from purchasing the expensive plant and materials whose idle time is more than the usage time.
- Government and their agencies should set example by patronizing the industrialized building system just as traditional building.
- Government should not be too strict in policy making which affect construction industry as no economic system can do without the industry.
- Government in conjunction with private organizations or individuals should take step to enlighten the public on the good quality possessed by the systems by jointly sponsoring seminars, workshops and any other public enlightenment carping this is to facilitate awareness in the public and foster the idea and improvement of operation of the system within the building industry.
- Tendering procedures for this system at present should modify so as to make the operations easier for both parties.
- In view of the high level of technology needed in the two system skilled manpower development units should be established in proprietary firms and the units should be responsible for organizing job training programs for its workers specifically on site erection. Training in technical schools, polytechnics and other institutions of higher learning should also be organized or encouraged for the study of this system of construction.
