This study is aimed at developing productivity models based on the combined usage of manpower and equipment resources in construction for tall residential building projects in India. Data was collected from 52 tall residential building projects in different locations for a consecutive period of 18 months for the five basic activities of construction: concreting, reinforcement, formwork, blockwork and plastering. Multiple linear regression analysis was used to develop 15 models - three models each in different conditions for the five basic construction activities for manpower and equipment productivity, and were validated with independent field data. In addition, the factors affecting productivity of manpower and equipment were analysed through a qualitative study by collecting and examining responses to questionnaires from 96 respondents involved in the 52 projects. The study found that improper planning of work was the most important factor affecting the productivity in tall residential building projects. The models developed in the study, and the analysis of factors affecting productivity will be useful to cost engineers and project managers to estimate the productivity of resources in tall residential building projects in India and other developing countries where similar conditions prevail.
