Design, Build & Maintain- (DBM), and Design, Build, Finance & Maintain contracts (DBFM) are increasingly applied in the Dutch civil engineering industry. These project delivery methods have in common that the private party is made responsible for the aspects design, build and maintenance. By integrating these three aspects, client organisations aim to stimulate an increasing role for life cycle costing in the early life cycle stages, which results in a high-quality infrastructure system with optimal life cycle costs. A DB(F)M-contract requires a different approach from the market than a traditional contract. The contractor is supposed to combine its expertises in the field of design, build & maintenance in order to win the contract, and subsequently execute the project successfully.
