Abstract:Since a few years the division Infra of Dura Vermeer operates in a strong changing market. Government awarding authorities which Dura Vermeer depends on, tender more substantial and complex projects spanning several years. This market demands control of the total project from the tender phase to maintenance. The value-adding chain of a project has often been neglected as a result of the separated division of work in the building industry. Each phase in the building process has its own distinctive properties and each phase is seen as a separate project by a contractor. New insights in the way how the life cycle of a project and the accompanying costs must be perceived have reached the building industry. The life cycle thus the (desirable) outcome for users, management and the life cycle costs of the materialized product are seen in a new perspective. Dura Vermeer Asset Management has stepped in the market and embraces the life cycle approach. Part of this life cycle approach for Dura Vermeer Asset management is a risk-based maintenance concept which can take the complete life of an asset in account. The risk-based method FMECA or Failure Mode, Effects and Criticality Analysis structurally analyses the possible means of failure, the impact of failure and the risk of failure of components. The goal of a FMECA is in principal to develop an optimal maintenance concept (also possible for different designs). As has been stated this is done on a risk base. Every component in a system has a certain risk of breaking down. In some cases the consequences of breaking down do not have an influence on the system and are less critical than components who do have a big impact. This socalled criticality of components is coupled to corporate goals. In this manner the influence of a broken down component is added to a maintenance concept. For example if availability of the road is implemented as a corporate goal, and all threats which jeopardize this goal must be eliminated, the maintenance concept can be adapted to reach that goal. This Bachelor’ thesis concerned researching the applicability of FMECA within infrastructure projects. A roadmap consisting of eight steps has been constructed to get to satisfying results. In each step is worked towards constructing a model of a system. In this case the provincial road N31 was used to implement FMECA
