We know that construction is the world’s largest and most challenging industry. Labor productivity and poor productivity are being faced by most of developing countries. The main aim of this Paper is to identify critical factor which affects construction labor productivity and to use them for developing a predictive model. This paper presents the factors which affect the labor productivity for the residential and commercial buildings within Surat city, Gujarat. By literature review total 47 factors were finalized that affects the labor productivity within the scope of work and distributed in eight main categories as: Management, Supervision, Safety program and motivation, Technical excellence and site layout, Proper planning and schedule, Labor competence, Effective communication and language understanding, and External condition. The analysis to find out the most influencing factors has been done using the Mean Variance Method through the SPSS tool. After finding top 11 factors, an ANN models is developed by using MATLAB software to predict labor productivity. Amongst various trials, we found that 85%-15% FFDTD is the best model for the prediction. At last, we took four case studies for validation of ANN Model on ongoing projects in Surat which has shown the satisfactory results in predicting the productivity.
