Evaluation of Contractor Performance on Project Cost Control in Building Construction

CHAPTER ONE

1.1 Background of the Study

Cost control is one of the most critical aspects of construction project management. It ensures that projects are executed within approved budgets while maintaining desired quality and timelines. Contractors play a vital role in this process because they manage the resources, labor, and materials that determine financial outcomes. According to Ameh and Osegbo (2019), effective cost control depends on the contractor’s ability to plan, monitor, and adjust project expenditures throughout the construction phase.

In building construction, poor cost management often results in cost overruns, delays, and disputes between clients and contractors. The performance of contractors in cost control therefore determines the financial success of any project. As Olatunji (2020) observed, contractors who implement effective cost management systems and adopt modern technologies can significantly reduce waste and improve profit margins. However, when contractors fail to track expenses properly, projects experience financial stress and reduced profitability.

Modern construction projects demand a high level of financial discipline and transparency. Contractors are expected to apply cost control techniques such as value engineering, cash flow analysis, and earned value management. Quantity surveyors also collaborate with contractors to monitor budget performance and provide cost reports. This study therefore evaluates how contractors perform in controlling costs during building construction projects and identifies the key factors influencing their cost control efficiency.

1.2 Statement of the Problem

Despite advances in cost management techniques, many building projects still experience cost overruns. These overruns are often linked to poor contractor performance in cost control. Factors such as inadequate planning, weak supervision, inflation, and inefficient resource allocation contribute to cost escalation (Akinradewo & Oke, 2019).

In many cases, contractors focus on completing projects within deadlines but neglect the importance of financial discipline. Some lack proper cost control mechanisms or rely on outdated manual methods that cannot track expenses in real-time. This situation undermines project success and reduces client satisfaction.

Therefore, there is a need to examine how contractors perform in project cost control and to identify strategies that can enhance their effectiveness in managing construction finances.

1.3 Aim and Objectives of the Study

The main aim of this study is to evaluate contractor performance on project cost control in building construction.

The specific objectives are to:

1. Assess the cost control practices adopted by contractors during building construction.

2. Determine the major factors affecting contractor performance in cost control.

3. Examine the impact of contractor performance on overall project cost outcomes.

4. Propose strategies to improve contractor efficiency in project cost management.

1.4 Research Questions

1. What cost control practices do contractors adopt in building construction?

2. Which factors affect contractor performance in cost control?

3. How does contractor performance influence project cost outcomes?

4. What strategies can enhance contractor efficiency in cost management?

1.5 Significance of the Study

This study is significant because it contributes to understanding how contractor practices influence project costs. According to Ameh and Osegbo (2019), effective cost control by contractors reduces waste, improves accountability, and ensures that clients receive value for money. The findings will help contractors identify gaps in their cost management systems and adopt better practices.

For clients and consultants, the study provides insights into how contractor performance can affect financial outcomes. It will also assist policymakers and professional bodies in developing training programs that strengthen contractor competence in cost control. Academically, it adds to literature on construction project management and financial control.

1.6 Scope of the Study

The study focuses on building construction projects, emphasizing contractor performance in cost control. It examines cost planning, monitoring, and reporting practices among medium and large-scale contractors. The study also covers the role of supervision, resource allocation, and technology adoption in cost management.

1.7 Limitations of the Study

The study may face challenges such as limited access to contractors’ financial records and reluctance to disclose sensitive cost information. Time constraints and varying project sizes may also affect the comparability of data. Despite these limitations, reliable data and professional insights will be used to ensure credible findings.

1.8 Definition of Terms

• Contractor Performance: The effectiveness of a contractor in managing project resources, cost, and time to achieve desired results.

• Cost Control: The process of monitoring and regulating expenditures to ensure that project costs remain within approved budgets.

• Building Construction: The process of constructing residential, commercial, or institutional buildings.

• Quantity Surveyor: A professional responsible for estimating and controlling construction costs.
