Concern #570 - Ground Conditions and Productivity Uncertainty Driving Schedule and Cost

Project:
269 - Water Industry Development Project

Description:
The project is experiencing risks due to uncertain ground conditions, asset condition variability, and inconsistent construction productivity. These factors contribute to potential schedule and cost volatility, which are not fully accounted for in the current baseline plans or QSRA/QCRA assumptions. The situation is worsened by incomplete investigation data and access constraints that hinder comprehensive surveys, leading to reliance on generic productivity assumptions.

Desired Outcome:
Manage and mitigate risks associated with ground conditions and productivity variability to ensure schedule and cost estimates are realistic and based on comprehensive data.

What Could Go Wrong:
Unmanaged risks could lead to hidden exposures, resulting in late-stage overruns, claims, and the need for reactive replanning.

Current Situation:
Uncertainty in ground conditions and productivity persists, with existing plans potentially underestimating associated risks.

Action Strategy:
Make uncertainties explicit by using ranges and discrete risks, linking them to specific workfronts and milestones, and updating assumptions as more evidence becomes available.
