Delivering a water treatment plant project using a collaborative project procurement approach

Purpose - The purpose of this paper is to explore an interesting complex infrastructure construction case study project in which the initiation/design and delivery phases were managed differently, with diverse assumptions and workplace culture. It uses a recently developed collaboration and relationship-based procurement taxonomy to analyse the decision to commence a project and to deliver the project. The taxonomy tool reveals underlying assumptions and helps explain actions taken. The paper provides a window into the decision-making process. It also illustrates levels of innovation applied at the design and delivery phases. Design/methodology/approach - A case study was undertaken, primarily using recorded and transcribed interviews, with five key senior participants in the project. This gathered a client, designer and contractor perspective that was subsequently analysed using a sense-making approach. Findings - It is possible to start a project adopting a highly collaborative approach that maximises innovation, understanding complexity and developing a design that can then be delivered using a more traditional approach. The taxonomy used demonstrates that it is a useful visualisation tool for this purpose. Research limitations/implications - The research was limited to the perspectives of only five individuals even though they were key decision-makers and had a robust overview of the project as a whole. The delivery phase was chosen as a matter of policy without the ability to break loose from that policy. The implications for beginning the initiation and design process in a highly collaborative hands-on mode influenced the understanding of all parties involved in the project in a positive direction. The case study was based in Australia, which has extensive experience of collaborative project delivery approaches. Practical implications - The taxonomy and its ability to provide visualisation of the e
