Construction sector is diverse as it contains contractors, consultants, designers, owners, and others. Productivity is a problem in many countries and one of the most important factors that affects the overall performance of any small or medium or large construction industry. This paper explainsthat thefactors affecting labour productivity in Indian construction industry through various researches and analysis gives suggestion to improve the productivity and justify extreme affecting factors. KEYWORDS: labour productivity, factors, improvement, suggestions. I. INTRODUCTION In construction labour productivity is one of major elements of every company success and competiveness in construction industry. Labour cost is important from project cost. It includes almost 30-50% from overall cost. (bitar, 2012). The new methods to implement by development of machinery and improved in the total productivity methods. The concept of productivity includes need to be quality of input, output and process. Labour productivity determines economy of projects; it has control over labour productivity. Labour productivity is calculated by ratio of output to the working hours or labour costs. (B. prakash rao, 2015) Labour is more variable and unpredictable than other project cost components, it becomes necessary to understand the effects of different factors on labour productivity. Researchers many identified as factors affecting labour productivity in construction from various countries all over the world and only few of them found Indian construction industry. In this study we are going to identify that different factors affecting labour productivity in Indian construction and ranking the factors need to implement solutions to improve the productivity levels from questionnaire survey.From the previous study we identified the 35 factors that affecting labour productivity and they divided into 8 groups by which namely,1. Supervision (5 factors), 2.Manpower (5factors) 3. Motivation (4factors) 4. Safety (7factors) 5. Material (3factors) 6.project(6groups) 7.Contactors ( 3 factors) 8. External (3factors). Here we are discussed about the top 3 groups and their affecting factors to find the solution to improve them and justify the results.According to RII, method the top 3 groups are 1.project 2.safety 3.motivation . II. FACTORS This study groups the following affecting factors are method of construction, delay in payment of workers, ineffective planning and scheduling of works , poor site condition, poor design in existing drawings.The below table shows the importance index of the factors from the project group, III. SUGGESSTIONS For project group:The method of construction is the first negative factor in this project group, use of proper method of construction for any type works at site is added value to the productivity. This is to justify by use of
