Thesis Abstract

Abstract
Construction costs in Nigeria have been a topic of concern due to the various factors that influence them. This research project aims to analyze and identify the key factors that affect the cost of construction in Nigeria. The study will focus on both external and internal factors such as economic conditions, government policies, material prices, labor wages, project location, and project size. The research will involve a comprehensive literature review to understand the existing knowledge and theories related to construction cost factors. Additionally, primary data will be collected through surveys and interviews with industry professionals, contractors, and developers to gather real-world insights and experiences. The data analysis will involve both quantitative and qualitative methods to provide a holistic view of the factors affecting construction costs in Nigeria. The findings of this research will contribute to the existing body of knowledge by providing an in-depth understanding of the various factors that impact construction costs in Nigeria. By identifying and analyzing these factors, stakeholders in the construction industry can make informed decisions to mitigate cost overruns and improve project delivery efficiency. The research will also offer recommendations and strategies for managing construction costs effectively in the Nigerian context. Overall, this research project is essential for addressing the challenges and complexities surrounding construction costs in Nigeria. By shedding light on the key factors influencing construction costs, the findings of this study can help improve cost estimation accuracy, budget planning, and overall project management in the construction industry. The insights gained from this research will be valuable for industry professionals, policymakers, and researchers seeking to enhance cost control practices and optimize construction processes in Nigeria.

Thesis Overview

 1.0 INTRODCUTION 

1.1 BACKGROUND STUDY 

The growing need for construction of all types coupled with a tight monetary supply has provided the construction industry with a big challenge to cut cost. According to Mendelson and Greenfield (1996) the remaining part of the twentieth century would involve corporations, institutions and government in a race to survive. The attendant dwindling economic fortune of nations economies around the World have geared up the participant in these sectors (the client in particular) to take up the challenge of ensuring efficient use of their resources to obtain value for money in terms of performance. The total cost of construction in normal circumstances is expected to be the sum of the following cost: Materials, Labour, Site Overheads, Equipment/Plant, Head office Cost and Profit but in many parts of the world particularly in Nigeria, there are other costs to be allowed for. These costs according to Mbachu and Nkado (2004) have obvious negative implications for the key stakeholders in particular, and the industry in general. To the client, high cost implies added costs over and above those initially agreed upon at the onset, resulting in less returns on investment. 

To the end user, the added costs are passed on as higher rental / lease costs or prices. To the consultants, it means inability to deliver value - for - money and could tarnish their reputation and result in loss of confidence reposed in them by clients. To the contractor, it implies loss of profit through penalties for non- completion, and negative word of mouth that could jeopardize his/her chances of winning further jobs, if at fault. The proposed work will investigate and report the other costs to be allowed for, which are the basic factors affecting construction cost in Nigeria and also proffer solutions to how construction cost can be minimized.

1.2 STATEMENT OF PROBLEM

The demand for more construction of all types, coupled with a tight monetary supply has provided the construction industry with a big challenge to cut costs. The problem of high contract costs of all aspects of construction is becoming obvious. Consequently, substantial increases are being observed in projects. This substantial increase has brought about loss of client confidence in consultants, added investment risks, inability to deliver value to clients, and disinvestment in the construction industry.

1.3 AIMS AND OBJECTIVES OF STUDY

The aim of the study is to find out the factors affecting construction cost in Nigeria and proffer solutions to how construction cost c an be minimized. The objectives of the study are as follows: 

1. To identify the main factors affecting construction cost in Nigeria. 

2. To determine the severity rank of the factors amongst clients, consultants and contractors. 

3. To determine the agreement ranking factors between clients, consultants and contractors. 

4. To proffer solutions on how to minimize construction cost in Nigeria.

1.4 RESEARCH HYPOTHESES

To test the hypothesis: 

1 (a). Ho: Contractors and Clients do not generally agree on the severity rank of the factors affecting construction cost in Nigeria 

1 (b). H1: Contractors and Clients generally agree on the severity rank of the factors affecting construction cost in Nigeria 

2 (a). Ho: Clients and Consultants do not generally agree on the severity rank of the factors affecting construction cost in Nigeria 

2. (b) H1: Clients and Consultants do not generally agree on the severity rank of the factors affecting construction cost in Nigeria 

3. (a) Ho: Consultants and Contractors do not generally agree on the severity rank of the factors affecting construction cost in Nigeria 

3. (b) H1: Consultants and Contractors generally agree on the severity rank of the factors affecting construction cost in Nigeria.

1.4 SIGNIFICANCE OF THE STUDY

An assessment of the study would enable Clients, Contractors and Consultants give an economic approach to construction work such that they would be able to identify the dominating factors leading to high construction cost in Nigeria. The application of the solutions proffered to minimizing construction cost would restore client’s confidence in consultants, reduce investment risks, and generally boost the viability and sustainability of the industry.

1.5 SCOPE AND DELIMITATION OF STUDY

The scope of this research is limited to identification of essential factors affecting construction cost and proffering solutions on how to reduce construction cost in Nigeria. The study is limited to projects in the Lagos metropolis of Nigeria because there is easy access of information in the Lagos metropolis by the researcher. Target respondents for this study are the principal actors in the construction industry namely: the Client, the Consultant and the Contractor.
