Abstract:
This study was conducted to examine the effectiveness of the learning curve theory in labor
cost of construction project. It also identifies the factors from literature survey as well as
respondents. That affect the labor learning development by conducting a questionnaire
survey. Learning curve theory is based on the phenomenon that learning development
improves through the repetitive tasks. In construction planning, the evolution of repetitive
scheduling methods led to the introduction of learning concept. It is a common knowledge
that execution of the same activity repeatedly, and in the same condition takes less time as
the activity is repetitive in nature. This phenomenon is clear in many construction activities
and is known as learning experience or learning effect. It contributes a development of
algorithm for predicting construction activity time based on learning curve theory. This
technique used widely to forecast cost. Learning curve is a geometrical progression which
reveals that there is steady decrease in cost for the accomplishment of a given repetitive
operation, as identical operation is increasingly repeated. It was discovered that the learning
curve effect brings about a decline in labor cost and consequently operational costs hence, a
low contract price. ANOVA, CHI Square, Criticality index, Frequency test and Pot Hoc
analysis were used to analyze the identified influenced factors on learning curve theory.
