A Constructive System to Assess the Performance-based Grading of Construction Labour through Work-Based Training Components and Applications

Various industry sectors of many developing countries have been facing various challenges associated with low performance of labour due to poor work-based training practices. This study aims to assess the performance of labour in construction by applying systematic work-based training components. A comprehensive study methodology was adopted through literature reviews and experts’ interviews/discussions, with problem-focused and action-oriented communication approaches to develop effective tools, systems and practices related to labour training elements and performance assessments within a framework. Through a new construction supervisory training programme, the developed practices were applied to 200-300 labourers working on 23 construction projects in Sri Lanka. The results show the detailed patterns of the significant changes in labour performance with the quantified values. Overall quantitative values indicate a nearly 60% increase in the performance of labour within six months of the training period compared to the starting point. A considerable level of performance improvement was reported in the soft skills (90%) and material handling abilities (70%) of labourers. A moderate level of performance improvement was identified in other competency elements related to the application of basic science/technology-related practices (55%), simple engineering/technology-related practices (44%), construction methods and technology (56%), green practices (36%) and fundamental management aspects (34%). The overall performance values of labourers employed in road/bridge projects were found that noticeably lower compared to the labourers who worked on other types of projects. The results further describe the well-improved theoretical knowledge and operational skills of the trained labourers, which has uplifted their job standards from working under close supervision to working under general supervision with some autonomy. Moreover, the study findings contribute to controlling the excessive inclination of local firms toward foreign labour by unlocking the potential barriers to expanding the local labour supply with lifelong learning and career benefits/opportunities for labourers. The findings will have a significant impact on how other developing nations and industries must manage their labour to obtain higher work efficiency in the foreseeable future.
