Lean Construction Practice and the Challenges in Nigeria

Abstract

The Nigerian construction industry us characterized by wastage of construction resources as a result of disruption, thus, the need for a construction delivery system that seeks to coordinate the numerous processes and operations in order to maintain required work flow in a manner that minimizes waste, cut undesirable cost, and adds value. The study aims at evaluating the extent to which limited knowledge impact on lean construction practices in Nigeria. The method of study involved a critical exposition of related literature and an empirical study employing the t-statistic for data analysis. A structured questionnaire was issued each to a sample size comprising 67 firms drawn from a finite population of 80 medium-large size construction firms operating in South-eastern Nigeria, using Taro Yamane Formula. The result of the study revealed a low knowledge of lean construction core competencies and a scanty application of lean construction in Nigeria. The study concludes that ignorance and a lack of in-depth knowledge of lean construction competencies is largely responsible for the low level of application, hence the wastages that characterize construction industry in Nigeria. The study recommends an improved awareness of lean construction competencies through formal education and informal training.
