Abstract
Construction sector has always been dependent on manpower. Most of the activities carried out on any construction site are labour intensive. Since productivity of any project depends directly on productivity of labour, it is a prime responsibility of the employer to enhance labour productivity. Measures to improve the same depend on analysis of positive and negative factors affecting productivity. Major attention should be given to factors that decrease the productivity of labour. Factor analysis thus is an integral part of any study aiming to improve productivity. Interpretive structural modeling is a methodology for identifying and summarizing relationships among factors which define an issue or problem. It provides a means to arrange the factors in an order as per their complexity. This study attempts to use the latest version of interpretive structural modeling i.e. total interpretive structural modeling to analyze factors negatively affecting construction labour productivity. It establishes interpretive relationship among these factors facilitating improvement in the overall productivity of construction site.
Highlights
Construction industry is a labour oriented industry
Labour productivity has been a matter of very high importance in construction industry
Application of Total interpretive structural modeling (TISM) to better understand the factors contributing to labour productivity provides an intellectual way to analyze the situation and plan the corrective actions to improve upon overall performance of the construction site
Summary
Construction industry is a labour oriented industry. Construction is a craft-based activity and the labour behaviour has a large influence upon the organization and overall performance of any construction firm. Construction projects are characterized by their uniqueness. They have long been considered to have the highest labour component in comparison to other industries Jr. and McKee K.E., 1981; Arditi, 1985; Thomas et al, 1990; Kaming et al, 1996; Moselhi O. and Khan Z., 2012). Labour cost comprises 30 to 50% of the overall project’s cost, and is regarded as a true reflection of the economic success of the project (Jarkas A. and Bitar C., 2012)
