Chapter One — 1.1 Background to the Study

Over the past decade, the relationship between cost estimation techniques and project cost performance has become a subject of considerable debate among scholars and industry practitioners alike, particularly within the context of Lagos State where operating conditions differ markedly from more developed markets.

Within the context of Lagos State, this relationship carries particular significance. Organizations in this setting operate under a distinct combination of economic, regulatory, and market conditions that may amplify or dampen the effect of cost estimation techniques on project cost performance, making a context-specific inquiry both timely and necessary.

1.2 Statement of the Problem

Despite a growing body of literature on cost estimation techniques, there remains limited consensus on the precise nature of its relationship with project cost performance, particularly within Lagos State. Many organizations continue to make decisions about cost estimation techniques without a clear, evidence-based understanding of how those decisions ultimately affect project cost performance. This gap between practice and empirical understanding is the central problem this study seeks to address.

1.3 Objectives of the Study

1. To examine the effect of Cost Estimation Techniques on project cost performance in Lagos State.
2. To assess the extent to which cost estimation techniques influences project cost performance within the study area.
3. To identify the challenges associated with cost estimation techniques in relation to project cost performance.
4. To recommend strategies for optimizing cost estimation techniques in order to improve project cost performance.

1.4 Research Questions

1. What is the effect of cost estimation techniques on project cost performance in Lagos State?
2. To what extent does cost estimation techniques influence project cost performance within the study area?
3. What challenges are associated with cost estimation techniques in relation to project cost performance?
4. What strategies can be adopted to optimize cost estimation techniques in order to improve project cost performance?

1.5 Significance of the Study

Beyond its academic contribution to the field of quantity surveying, this study has practical value for management teams within Lagos State seeking to understand how cost estimation techniques translates into measurable outcomes around project cost performance. It is equally useful to students and future researchers looking for a localized empirical reference on this relationship.

1.6 Scope of the Study

The study is limited to an examination of Cost Estimation Techniques and its relationship with project cost performance within the context of Lagos State. It reflects a clearly defined scope of analysis and relies on data and perspectives available within that scope; generalizing the findings beyond this specific context should therefore be done with appropriate caution.
