An MCS–based Model to Qualify the Relationship between Worker’s Experience and Construction Productivity

Construction productivity is affected by many negative factors. Many previous studies have been conducted to investigate them and propose some solutions for productivity improvement. One of the main factors affecting construction productivity is a worker's skill and experience. Based on a survey with respondents in eight building projects, this study has found that formwork construction workers' average labor productivity is constant if their experience years are higher than 12 years. The actual productivity of formwork is higher than the baseline productivity. Eventually, a Monte Carlo simulation model has been developed by using a normal distribution and uniform distribution. The simulation results showed that the probability of obtaining the expected productivity is very high, with a standard error of only 2%.
