The requirements that a quay design should meet in order to yield a viable port infrastructure, vary widely from flexibility due to future customers requirements to durability due to owners requirements. In a Port of Rotterdam backed project, current and future requirements have been aggregated by combining expertise present within 4 different organisations. Current experiences have been combined in a FMECA (Failure Mode Effect and Criticality Analysis) in which today's requirements with respect to maintenance management can be retrieved. Future needs have been assessed by determining trends in logistic flows and the development of the market position of the Port of Rotterdam. Current needs and future requirements have been combined in design, maintain and demolish requirements for "quay 2030" within an LCC approach that incorporates cost/benifit analysis. The costs involved have been assessed by their present value. Functional requirement scenarios that may develop have been incorporated by specifying the probability of occurrence in those scenarios. Scenarios for logistic changes that may influence the infrastructure have been appended to these scenarios. This led to the formulation of location specific scenarios for the development of the functional requirements for that particular area. Design proposals can be benchmarked for their performance under these scenarios. Re-use and demolish scenario's are incorporated. This process will be elucidated by means of an example. The risk of occurrence of specific demand for future maintenance have been incorporated by assessing and tuning this risk against the costs of preventive measures and quality improvements in the cost-optimum. When calculating the costs of investment and maintenance management in combination with the yields for various designs under different future market scenario's, the optimal design for the current requirements has been assessed. Incorporating the various aspects within one approach, a performance based methodology for quay design has been realised that meets both cost-effectivity requirements of the owner as well as the performance and cost requirements of the user. Project characteristics, resulting requirements and viable designs are highlighted within this Fit For Purpose (FFP) project approach. This project yields an example for design requirements that are apt for use within DCB(F)M constructions, since both flexibility and durability requirements are balanced within one life-cycle oriented framework. The project has shown us that Quay2k30 is not a specific design but is a location specific design that is based upon a prediction for the development of the Functional requirements with time.
