Internal and External Factors Impacting Construction Labour Productivity for Glazing of Doors and Windows
Abstract: The efficiency of glazing installation during building construction is impacted by internal and external factors, which affect labour productivity. External factors are exogenous to the construction sites but have an overarching influence on the productivity of site operations, while internal factors emanate from the construction firms and their site operations. This study examines the internal and external factors impacting construction labour productivity for the glazing of doors and windows, using …
