1.1 Introduction
Inflation refers to the rate at which the general level of prices for goods and services rises, leading to a decrease in purchasing power. It is often measured by the Consumer Price Index (CPI), which tracks changes in the prices of a basket of consumer goods and services (Baffes, 2015). The construction industry is a vital sector that significantly influences the economic development of a region, serving as a barometer for overall economic health. In Yenagoa, the capital of Bayelsa State, Nigeria, the impact of inflation on construction costs has become increasingly pronounced in recent years. Inflation, defined as the general increase in prices and the subsequent decrease in the purchasing power of money, poses a critical challenge to the construction sector, affecting project feasibility, timelines, and quality (Afolabi et al., 2020). As the cost of raw materials, labor, and equipment rises, construction firms are often forced to adjust their budgets and project scopes, leading to delays and reduced investment in infrastructure (Obi & Nwankwo, 2019).
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Scope of work, Research hypothesis and questions, Limitation of the study and Definition of terms.
1.2 Background of Study
In recent years, Yenagoa has continued to experience fluctuations in inflation, influenced by local and national economic conditions. The effects of inflation on construction costs have become a critical area of concern for contractors, policymakers, and investors. Various studies have documented the correlation between inflation rates and construction costs in Nigeria, emphasizing the need for strategic planning and adaptive measures within the industry (Ugwunta & Okoye, 2021).
Historically, construction industry in Yenagoa, Bayelsa State, is intertwined with the socio-economic dynamics of Nigeria, particularly concerning the impact of inflation on construction costs. Since its establishment in the early 1990s as the capital of Bayelsa State, Yenagoa has witnessed significant infrastructural development driven by government initiatives and private investments. However, the rapid fluctuations in inflation rates over the years have posed substantial challenges to the construction sector (Eteh, 2018). in the 1990s, the Nigerian economy experienced high inflation rates due to a combination of political instability, economic mismanagement, and fluctuating oil prices. These factors severely affected the construction industry, leading to increased costs for materials and labor. Consequently, many projects in Yenagoa were delayed or abandoned, impacting the overall growth of the region’s infrastructure (Ojo, 2019). Rising costs for imported materials and disruptions in supply chains further complicated project budgeting and delivery timelines, leading to calls for improved economic policies to support the construction sector.
The construction industry plays a crucial role in the economic growth and development of Yenagoa, the capital of Bayelsa State, Nigeria. This sector is not only fundamental for infrastructure development but also serves as a catalyst for job creation and economic diversification. However, the construction industry in Yenagoa has faced significant challenges, particularly in recent years due to the rising levels of inflation. Inflation, which refers to the sustained increase in the general price level of goods and services over time, has direct implications for construction costs, affecting everything from raw materials to labor (Okeowo & Olasunkanmi, 2019).
In Yenagoa, the effects of inflation on construction costs are exacerbated by a variety of factors, including fluctuating prices of construction materials, inconsistent supply chains, and economic instability. These challenges can lead to cost overruns, project delays, and, in some cases, abandonment of projects altogether (Ajayi & Adediran, 2020). As inflation rises, construction firms often find it increasingly difficult to predict costs accurately, which complicates budgeting and financial planning. This unpredictability can discourage investment in the construction sector, thereby stunting economic growth in the region (Nwankwo & Okeke, 2021).
According to Afolabi et al., (2020), the socio-economic context of Yenagoa characterized by a high rate of poverty and limited access to financial resources compounds the impact of inflation on construction costs. Many potential clients may struggle to secure financing for construction projects, making it difficult for contractors to obtain sufficient capital to absorb rising costs. This situation highlights the need for a comprehensive understanding of the relationship between inflation and construction costs to inform policymakers and industry stakeholders (Afolabi et al., 2020). Therefore, in Nigeria where the research was carried out, the activities that was conducted is to know the impact of inflation on construction cost.
1.3 Statement of Problems
Investigation revealed that inflation is contributing to the overall uncertainty in the market, leading to hesitancy among investors and stakeholders in committing to new projects. This reluctance is detrimental to the growth of the construction sector in Yenagoa, as potential projects may be postponed or canceled entirely due to fears of escalating costs (Eteh, 2018). Moreover, labor costs are also influenced by inflation, as workers demand higher wages to keep pace with the rising cost of living (Ojo, 2019).
The combined effects of material price increases, labor cost pressures, and market uncertainties are hindering the development of sustainable infrastructure. As a result, addressing the impact of inflation on construction costs is crucial for ensuring the viability and success of future construction projects in the region (Ugwunta et al. 2021).
1.4 Aim and Objectives of Study
The aim of the study is to examine the impact of inflation on construction costs in Yenagoa, Nigeria. In achieving this aim, the following specific objectives were laid out as follows:
