A construction company had to bore a 15 m diameter tunnel for a high-speed train line in an environmentally sensitive area. A kwantis consultant developed a schedule risk model to evaluate its criticalities.
The challenge
The tunnel’s schedule had to fit with contiguous line developments, and these interfaces needed special attention.
Our approach
The kwantis consultant applied a risk and performance management approach that included:
- the evaluation of uncertainties
- project progress measurement with Earned Value Management
- the evaluation of acceleration scenarios
A dedicated probabilistic model focused on the performance of the tunnel boring machine (TBM), to estimate its future performance.
The outcome
The project ended ahead of schedule, in line with the probabilistic schedule estimates. As a result, the company extended the risk and performance approach to other similar projects.
