Overall approach

R ISK - DRIVEN STRATEGY 1. First think Risk identify and analyse key risks to project goals, for each phase 2. It’s all about the process! define mitigating measures + implement control processes focused on managing the key project risks 3. Risk-driven strategy Good and Fast won’t be cheap CERES – February 2018

S ETTING CLEAR OBJECTIVES Aim for zero failure project > First-time-right! > Create a single common data environment > Integrate all engineering processes > Focus on requirements & interface management

De Groene Boog: Design of the tunnel cross section Why?  Reduce computing time of (repetitive) calculations and develop reusable scripts and collect data for data mining Parametric design scope?  Batch calculations of reinforcement using FE-tool (ideastatica).  Loads (traffic, ground- and waterpressure) by linking paramtric script to FE-tool (SCIA) Results  Simplify complexity by visual representation of issues  Reduce design time 11/5/2018
