S-Curve Progress Variance & Slippage Analyzer

Compute physical S-curve accomplishments and classify contractor schedule slippage.

Physical Quantities accomplished

Excavation & Subgrade (Weight: 30%)8,500 / 10,000 m³
0% doneAccomplishment: 85.0%
Concrete Canal Lining (Weight: 50%)1,800 / 2,500 m
0% doneAccomplishment: 72.0%
Reinforcement Steel (Weight: 20%)38,000 / 40,000 kg
0% doneAccomplishment: 95.0%
Overall Progress Status
Planned Progress88.0%
Actual Progress80.5%
SLIPPAGE (PV vs AV)-7.5%
-20%-15% (Termination)-10% (Warning)-5%0%+10%
Slippage Warning

Contractor must submit a Catch-up Program (revised schedule).

Weighted Progress Formula:

Overall Progress=∑(Task %×Weight)\text{Overall Progress} = \sum (\text{Task } \% \times \text{Weight})
Current Computation:
AV=(85.0%×0.3)+(72.0%×0.5)+(95.0%×0.2)=80.5%\text{AV} = (85.0\% \times 0.3) + (72.0\% \times 0.5) + (95.0\% \times 0.2) = 80.5\%
Slippage=80.5%−88.0%=−7.5%\text{Slippage} = 80.5\% - 88.0\% = -7.5\%
