Applying Learning Curve Theory in Construction Cost

Applying Learning Curve Theory in Construction Cost Estimating. If it is a 70% curve, it represents a 30% reduction in effort with every doubling of experience. Similarly, an 80% curve corresponds to a 20% reduction in effort. This percentage varies with the type of industry, from 60% to 95%. Normally an 80% curve is used in construction.

Refer to the addition to the total cost for producing an additional unit of the product. Marginal cost is calculated as MC = TC n = TC n-1. n= Number of units produced. It is also calculated as MC = ∆TC/∆Output. MC curve is also a U-shaped curve as marginal cost initially decreases as output increases and afterwards, rises as output increases.

Cost Curves UP

The average cost at a quantity of 50 units, is the slope of the ray from 0A, or $30 per unit. The marginal cost at a quantity of 50 units is the slope of the total cost curve at this quantity, which equals the slope of tangent line BAC. This tangent line's slope is 10, so marginal cost at 50 units is $10 per unit.
