The Impact of Unskilled Labor on Project Performance(An Empirical Study on Construction Companies in Yemen)

Abstract

A scarcity of skilled labor can have a substantial impact on project performance; the problem of unskilled labor performance is one of the critical components of labor construction performance that must be addressed in order for construction companies to execute successful projects. This study adopted a quantitative method approach and utilized a descriptive and explanatory research design. The total population for this study was 900 employees.

Krejcie and Morgan's's (1970) table wastable was applied for determining the sample size, and based on the total population (900), the sample size for this study is 269. The study's objectives were met by distributing a structured quantitative questionnaire to 269 respondents from construction companies, including project managers, engineers, laborers, supervisors, and contractors. The response rate was 100%. Cronbach's alpha isalpha is used to measure reliability and ensure consistent results. The findings indicate that lack of training inefficiently adversely impacts project performance. The study noticed that a lack of construction knowledge, workmanship, and experience did not independently predict project performance, their impact could be mitigated by results that include rework rates, productivity levels and overall task completion.
