The figure shows the different aspects and phases of the procurement framework. In contrast to the traditional purchasing process, this is a cyclical process. So we cannot see it as static or chronological. The various topics are part of the usual phases of a construction process. But in contrast to the traditional process, these topics are not just linked to each other, they can also be a source of feedback for each other. This creates a dynamic process. The arrows indicate that, within each phase, we need to both reflect on the formulated ambitions and think ahead in order to prevent risks and to seize opportunities in the following phase(s).
The middle four, larger circles correspond to the (classic) construction phases. The process starts with the initiative and typically continues until the end of the use phase or the end of life of a construction project. The model covers the entire life cycle of a building, based on the principle that there is no end of life. This is because in a circular economy we are committed to maximum maintenance and as high quality as possible reuse. The circles on the left and right of the model show which topics you might want to consider during the process in order to successfully achieve your ambitions in practice. The colours of the circles correspond to the phases where, based on the procurement framework, you need to pay extra attention to the given topic. If the topic in a certain coloured circle is continued (or actioned) in another construction phase, the ring around the circle is the colour of that next phase. This emphasises the strong link between the different phases. An important starting point is to pay proper attention to the circular and bio-based ambitions of the construction project.
The CBCI Procurement Framework was set up so that not only private but also – and above all – professional clients and professionals gain step-by-step insight into which aspects are important and which available approach can be used to successfully set up a bio-based circular industrial project.
