Chapter One: Introduction
Background of the Study
In the construction industry, accurate cost estimation is essential to ensure that projects are completed within budget and on time. Cost estimation techniques are used to predict the costs of materials, labor, equipment, and overheads required for construction projects. Effective cost estimation can help construction managers optimize resource allocation, avoid cost overruns, and improve profitability (Horngren et al., 2012).
Dikwa Local Government Area (LGA) is experiencing significant infrastructure development, with construction projects aimed at improving roads, housing, and public facilities. However, these projects often face challenges related to inaccurate cost estimates, leading to budgetary constraints and delays. Drury (2018) states that common cost estimation techniques include parametric estimation, analogy estimation, and bottom-up estimation, each offering varying levels of accuracy and applicability depending on the project type.
The effectiveness of cost estimation techniques in the construction industry is influenced by several factors, including the quality of available data, the skills of estimators, and the methods used. This study explores the effectiveness of cost estimation techniques in construction projects in Dikwa LGA, examining how these techniques are applied, their limitations, and their impact on project success.
Statement of the Problem
Construction projects in Dikwa LGA often suffer from inaccurate cost estimates, leading to budget overruns and project delays. This is partly due to the use of outdated or inappropriate cost estimation techniques. While cost estimation is a critical component of construction project planning, many contractors in Dikwa LGA lack the tools and expertise to accurately predict costs. This study investigates the effectiveness of cost estimation techniques in construction projects in Dikwa LGA, identifying challenges and proposing improvements.
Aim and Objectives of the Study
The aim of this study is to assess the effectiveness of cost estimation techniques in construction projects in Dikwa Local Government Area.
The objectives are:
1. To evaluate the use of cost estimation techniques in construction projects in Dikwa LGA.
2. To assess the accuracy and effectiveness of these techniques in predicting project costs.
3. To identify the challenges faced by construction firms in implementing effective cost estimation techniques.
Research Questions
1. What cost estimation techniques are used in construction projects in Dikwa LGA?
2. How accurate and effective are these techniques in predicting project costs?
3. What challenges hinder the accurate application of cost estimation techniques in construction projects?
Research Hypotheses
1. Cost estimation techniques used in construction projects in Dikwa LGA are often inaccurate.
2. The use of effective cost estimation techniques improves the accuracy of project cost predictions.
3. Challenges such as lack of data and limited expertise significantly hinder the effective application of cost estimation techniques.
Significance of the Study
This study provides valuable insights into the effectiveness of cost estimation techniques in the construction industry, offering recommendations for improving cost accuracy and project planning. The findings will contribute to enhancing construction management practices in Dikwa LGA and provide a foundation for future research in construction cost management (Bhimani et al., 2019).
Scope and Limitation of the Study
The study focuses on construction projects in Dikwa Local Government Area and evaluates the effectiveness of cost estimation techniques. Limitations include the availability of reliable cost data and potential biases in self-reported information from construction firms.
