Bélier Solutions is based in The Netherlands. Our speciality is flood defence systems and hydraulic structures. In addition, we offer consultancy on structural risk and reliability in general. Living structural systems driven by deterioration and other time-dependencies inform the design of inspection and maintenance programmes. Our solutions fit in life cycle costing modelling with varying complexity. The basis is the analytical framework based on Bayesian decision-making. In practice, limited resources often restrain full model development. We deliver intelligent solutions that support practical decisions.
