Weighted Construction-Completion Calculator

Calculate overall completion from three work-package percentages and visible weights.

Why it matters: Visible geometry and quantity arithmetic improves field coordination and makes allowances available for review.

Engineering interpretation

The three entered work packages are 47.5% complete on the visible weighted basis.

Important limitations

  • Progress arithmetic only. Verify weight basis, earned-value rules, physical completion definitions, stored materials, rework, quality holds, and contract payment provisions.

C_w=Σ(w_iC_i)/Σw_i
displayed symbols: C_1, w_1, C_2, w_2, C_3, w_3
Current substitution

C_w=(100×20+50×30+25×50)/100=47.5%.

Calculation sequence

Step-by-step method

  1. Confirm dimensions, formula symbols, unit system, and measurement sources.
  2. Apply the displayed geometry, quantity, or field-control equation.
  3. Review allowances, tolerances, constructability, and governing project requirements.
