Development of conceptual motivation framework to improve construction labour productivity in the U.K.

Motivation is essential because labour performance depends on motivation. The study presents vital motivation factors influencing labour productivity and the relationship between social compliance, motivation, and productivity for decision-making. The construction industry in the U.K. is to become the largest construction market by 2030. However, construction productivity in the U.K. is low relative to other industries, resulting in a skilled labour shortage and low productivity growth. Hence, the opportunities for research to improve productivity in constructing for the future through motivation by social compliance. The study conducts a critical literature review of 32 significant motivation and productivity articles from construction and other industries in an online database to identify 31 factors. The findings indicate that motivation mediates social compliance and productivity. The study developed a conceptual motivation framework that indicates a positive relationship with motivation, social compliance, and productivity. The next stage is empirically testing the framework on sites.
