Chapter One — 1.1 Background to the Study

Over the past decade, the relationship between value engineering practices and accuracy of cost estimates has become a subject of considerable debate among scholars and industry practitioners alike, particularly within the context of Ogun State where operating conditions differ markedly from more developed markets.

Ogun State presents a useful setting for examining this relationship precisely because the conditions there — structural, regulatory, and behavioural — differ from those typically assumed in the broader literature, most of which draws on evidence from more developed economies.

1.2 Statement of the Problem

Despite a growing body of literature on value engineering practices, there remains limited consensus on the precise nature of its relationship with accuracy of cost estimates, particularly within Ogun State. Many organizations continue to make decisions about value engineering practices without a clear, evidence-based understanding of how those decisions ultimately affect accuracy of cost estimates. 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 Value Engineering Practices on accuracy of cost estimates in Ogun State.
2. To assess the extent to which value engineering practices influences accuracy of cost estimates within the study area.
3. To identify the challenges associated with value engineering practices in relation to accuracy of cost estimates.
4. To recommend strategies for optimizing value engineering practices in order to improve accuracy of cost estimates.

1.4 Research Questions

1. What is the effect of value engineering practices on accuracy of cost estimates in Ogun State?
2. To what extent does value engineering practices influence accuracy of cost estimates within the study area?
3. What challenges are associated with value engineering practices in relation to accuracy of cost estimates?
4. What strategies can be adopted to optimize value engineering practices in order to improve accuracy of cost estimates?

1.5 Significance of the Study

This study is significant to a range of stakeholders. For policymakers and regulators, the findings offer evidence to guide the design of frameworks that support healthier outcomes around accuracy of cost estimates. For managers and practitioners within Ogun State, the study provides practical insight into how value engineering practices can be better managed. Finally, it contributes to the academic literature on quantity surveying by extending existing knowledge into a specific empirical context, and offers a reference point for future researchers.

1.6 Scope of the Study

In terms of scope, this study confines itself to Ogun State, focusing specifically on how value engineering practices relates to accuracy of cost estimates within that setting. Findings are interpreted within these boundaries rather than as universal claims applicable to every organization or market.
