Abstract
The general view of most construction challenges points towards an inability to deliver value. Value creation has not been established enough in the construction industry, regardless of past initiatives to improve it. The literature review highlights the importance of practices that promote value creation, such as target value design (TVD), which has roots in both lean construction and value management, both of which support project environments with favourable features to generate value. With recent reports of TVD successes in various countries, researchers suggest more studies are needed on its wider applications in other procurement routes employing evidence-based decisions, especially in developing countries. However, the application of TVD in the Nigerian construction industry (NCI) has not been fully explored. Additionally, it is not clear how the current design management practices in the NCI align with the underlying benchmarks and practices of TVD. Attempting to develop an appropriate approach that advances current practice is challenging, largely due to a lack of empirical supportive data. Globally, the basic principles of TVD take time to comprehend and can seem discouraging when implemented for the first time on actual projects; the different levels of collaboration can be easily confused and wrongly used interchangeably in TVD projects, and there is also a need for TVD projects to report on value generation and quality as past research has focused more on cost and time savings.
In view of these challenges, this study of the NCI was undertaken to explore the current design management practices in relation to TVD, to implement TVD and to develop and test a framework to support construction stakeholders in the implementation of TVD. The applied nature of Design Science Research (DSR) was deemed appropriate for this research. Both qualitative and quantitative methods were used in this investigation. Data were collected from across the building, highways infrastructure and rail sectors of the NCI through observing 17 projects, conducting four in-depth case studies, conducting 101 interviews, and analysing 189 questionnaire survey responses. Initial results revealed a limited awareness of TVD, and that some fundamental TVD practices recognized by the literature partially aligned with current NCI design management practices. From the case studies findings, the level of implementation of individual TVD benchmarks ranged up to 81%. This is the first recorded case of TVD implementation in the NCI, with findings that support evidence of a positive impact in the literature. TVD has been successfully applied in both design and build and traditional procurement routes, especially at the construction stage of public and private sector projects concerning provisional and prime cost sums. Additionally, TVD in bid process was reported as beneficial as it fostered the early participation of selected tenderers during the tender process. Results reveal that TVD flourishes with both face to face and virtual collaboration.
The major conclusion is that value creation can be improved using a more structured process. The findings have highlighted the need for a guide to assist NCI professionals, thus prompting the development of the Framework for Implementing Target Value Delivery (FFITVD) with additional embedded processes and strategy enhancing its contribution, which have not been addressed in other frameworks. Thus, this framework expands over and beyond previous frameworks, which focused more on the pre-design and design stages of projects. Testing the FFITVD on a live construction project revealed that the framework is comprehensive enough to be understood by stakeholders and has the capability of sustaining the implementation of TVD. This research has continued to influence research in the USA, academics in the UK and practice in the NCI.
