Problems influencing craftsmen's productivity in Nigeria

The activity sampling technique was used on seven construction sites in Nigeria to determine how the working day was being utilised by craftsmen in bricklaying, joinery and steel fixing trades. Actual working time was observed to be 51% of the working day for bricklayers, 44% for joiners and 56% for steel fixers. The rest of the working day was spent on nonproductive activities. The problems causing nonproductive periods were identified via an operative questionnaire survey. The three highest ranking problems impairing craftsmen's productivity were lack of materials, inadequate tools and work repetition. © 1987
