Abstract: Productivity has an important role in construction industry. The level of productivity is the result of the driving, induced and restraining factors acting upon the workers.The main objective of the paper is to perform secondary data analysis on the factors affecting labour productivity in construction. The secondary analysis provides a cost effective way of understanding a research and also helpful in designing for primary analysis. Based on study it was observed that the secondary analysis techniques such as constant comparison analysis, classical content analysis and domain analysis identified fifty four factors and were grouped under nine groups namely workforce, management team, psychological, schedule compression, material/equipment, supervision, safety, external and miscellaneous. Secondary analysis is valuable for identifying the critical areas investigated during the primary analysis which will helpful in improving the productivity of the labour.
