Abstract: Purpose:Construction in Malta is generally characterised by small projects operated through fragmented contractual ties and limited technological advances. Through this study, the authors aim to examine the impact of changing client requirements on local construction, analyse the impact of these shifts on project expectations and explore how client requirements can be integrated into the ongoing design phases during the life cycle of the structure. Using a multi-million-euro, multi-phase residential, commercial, and redevelopment construction project as a case study, this paper presents an in-depth analysis of the short-term disruptions and long-term impacts while considering the implications for trade-offs. Methodology:A mixed-methods approach was used to conduct the analysis. Qualitative data collected from semi-structured interviews showed that projects have different impacts on relationships even when the same organisations work on different trades within the same project. The quantitative data collected was used to analyse the variations caused by trade-offs from the original contracted work packages. The case study setting represents an example of a phenomenological methodology. It adapts existing theories to interpret what happens by examining an example of a phenomenon of interest. Although the conclusions cannot be generalised to the whole construction industry, its merit is that it addresses relationships and processes and is therefore ‘holistic’ rather than limited to isolated factors. Findings:The findings, illustrate the effects or factors supported by the empirical data towards the main framework that supports the research study model for mapping trade-offs. The model is presented as a three-dimensional framework illustrating the dynamics of objectives, considerations, and time across project life cycles, and goes beyond the control parameters of the project management, cost, quality, and time triangle. Conclusion:A set of recommendations are presented in relation to the drawing up of project briefs, procurement strategies, and the limitations and implications of embedding client changes.
