Overall approach

CERES – February 2018

• 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

Aim for zero failure project

> First-time-right!

> Create a single common data environment > Integrate all engineering processes > Focus on requirements & interface management

Capturing & Modelling Strategy

• consistently risk-driven
• on a need-to-know basis

60+ CAD aspect models!

Integration of highway design (Bentley MX, Civil 3D) with structural design (Revit) and technical installations (AutoCAD 3D, Plant 3D)

MODELLING THE RETROFIT REALITY

BIM coordination as a constant control process

1 Coordination Model

67 CAD models federated in Navisworks, for (bi)weekly Baseline and Design Meeting

> to identify (interface) risks > to explore design and build strategies > to boost inter-disciplinary cooperation

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
