Exploring internal factors affecting construction labor productivity in Mumbai: a study using RII and fuzzy logic

Chaudhari, Rahul S. / Bhangale, Pankaj P.

Construction labor is a critical and unpredictable resource in India, and their productivity plays a significant role in project success. While previous research has explored the factors affecting construction labor productivity, this study focuses on internal factors within the organization’s control. Data were collected from 393 laborers working on high-rise building construction projects in Mumbai using a questionnaire. The study evaluated the relative importance of factors affecting construction labor productivity using the Relative Importance Method (RII). The top 10 ranking factors were then used to predict productivity using Fuzzy Logic. The study found that internal factors, such as the timely supply of materials, proper supervision, adequate tools and equipment, and clear communication, were among the most critical factors affecting productivity. The study also observed that constant input of 54 to 56% resulted in the highest productivity of 90.30%, while variable input led to a lower productivity of 50%. The research helps identify the pain points of construction labor at the site, enabling project managers to take appropriate actions to improve working conditions and enhance productivity. By addressing the identified factors, organizations can improve construction labor productivity and achieve better project outcomes.
