Its major concern is how to increase the productivity of labour. Bar Benders and Steel Fixers who are responsible for bending, cutting and fitting of reinforcement bars contribute majorly in timely completion of the project. Hence their productivity is important in the estimation of time taken by the activities and in estimating numbers of bar benders and steel fixers are needed to complete the work in time. Many intrinsic and extrinsic factors are contributing towards the productivity of bar benders and steel fixers but only few can be controlled by management. This paper represents the evaluation and identification of factors affecting the productivity of bar benders and steel fixer in an infrastructure project. These factors are analysed and ranked with the help of Analytic hierarchy process. After evaluation, top five components identified are Training, Bar Bender and Steel Fixer skills, Complexity in bar bending schedule, Distance between binding place to place of cutting and bending and Workspace which are bearing upon the productivity of bar benders and steel fixers. Keywords— productivity, Bar Benders, Steel Fixers, Analytic hierarchy process. I. INTRODUCTION Productivity is commonly defined as a ratio between an output value and an input value used to produce the output. There is nothing as dangerous to an economy as a decrease in productivities because it generates inflationary pressure, social conflict, and mutual suspicion (Drucker, 1980). This article is useful for construction/project manager, planning engineer and all those related directly or indirectly to project planning and management. The Bar Benders and Steel Fixers productivity can significantly contribute in timely completion of project. These norms are calculated and referred from reliable sources. As the productivity of Bar Benders and Steel Fixers varies with geographical locations across the world, these norms are more suitable for Indian scenario. These factors can certainly prove handy to project planning and management (PPM) personnel as they can use it for performing Bar Benders and Steel Fixers requirement calculation (of infrastructure projects) and for cross checking the existing daily progress report (DPR) of their site to know how well the Bar Benders and Steel fixers are performing. II. AHP Thomas L. Saaty. developed the analytic hierarchy process (AHP). The AHP is created to solve complex problems involving multiple criteria (multi-criteria decision making) (MCDM) process. The AHP is advantageous as it is designed to handle cases in which the subjective judgments of individuals are significant part of the decision process. Additionally, the AHP helps in reducing bias in the decision by incorporating a useful technique for checking the consistency of the decision maker’s evaluations. III.
