After the realization of the design, this design was put on the market and was contracted. Contractors who wish to enroll for this work made a cost calculation on the basis of this design and the given quantities, required to carry out this work. The contract costs of the several tenderers were handed over to the client, after which the work was awarded to the lowest bidder. About a decade ago, integrated contracts were introduced after which this type of contract has increasingly gained popularity. Now, these types of contracts are fully integrated in the procurement phase of large complex infrastructural projects. The main difference between the traditional contracts is the design responsibility. By integrated projects, this is for the contractor. In the past, this responsibility was for the client. Nowadays the client only set up the functional requirements. Due to this shift, the contractor has obtained an additional design task besides providing costs. On the basis of functional requirements no factual cost calculation can be made. First, a design should be made out of which the design quantities can be extracted. With this data the cost experts can begin to calculate. In a tender phase is it far from certain that the work can be acquired and realized. It is more likely that a tender will be lost because of the number of candidates competing. If this is the case, the destination of all the hard work – drawing up a tender bid- is the bin...
