Analysis of Labor Productivity in Floor Tiling

Abstract

This research aims to: 1) survey labor productivity in floor tiling during normal working hours (8 hours) based on data from 219 samples across 17 residential building construction projects in Bangkok and its vicinity between June and December 2024. The findings indicate that the average labor productivity for floor tiling was 1.815 sq.m./hr., with a minimum and maximum of 1.143 sq.m./hr. and 2.483 sq.m./hr., respectively. 2) Analyze the relationship between personal factors and labor productivity in floor tiling. The results reveal that employment type, number of support workers, age, and experience were significantly correlated with labor productivity at the 0.05 significance level. and 3) Develop a multiple linear regression model to predict floor tiling labor productivity. The model indicates that the most influential factors affecting labor productivity are the number of support workers, experience, employment characteristics, and nationality (ranked from most to least influential). The model demonstrates a 67.3 predictive accuracy.
