| Abstract | In recent years, identi fying and reducing waste has been the subject of several researchers around the world. Many construction personnel mainly focus on the material waste that ari se in the construction process, neglecting to improve the efficiency of the construction process. Different techniques have been tested and implemented to reduce the material waste in the Indian construction industry. Apart from the material waste there are some hidden waste s that are seen in the construction process. These wastes res ults in the wastag e of time le ading to delays in the project. Several techniques have been implemented to reduce these hidden waste in the construction process. Such wast es are termed as non - value adding act ivities. Non - value adding activities are defined as the activities which does not have value but consumes the duration of the construction process . This research mainly focus on identifying the hidden wastes in the construction process. Apart from identifying the non - value adding activities this study also explains the d ifference in durations of productive work, supportive work in the construction process. For identifying the wastes, two repetitive process, namely, brickwork and reinforcement work are considered in 3 medium rise residential building. Video recordings and stopwatch studies are conducted to estimate the durations of the each activity involved in the process . Finally the work is categorized into productive work (PW ) , supportive work (SW) and non - value adding work (NV) . After identifying the wastes in the con struction process, face to face interviews are conducted to find out the exact cause and sources of these non - value adding activities. The respondents mainly consists of project managers, site engineers, project engineers etc. who have at least 5 years of experience in residential building construction. Finally, a process mapping model is developed for brickwork and reinforcement work based upon the observations on - site. Analysing the three cases have revealed that there is a difference in the durations f or the productive work, supportive work and non - value adding work in the construction process. This is mainly due to the difference in the construction method, productivity of the worker and utilization of the modern equipment in the construction activitie s. Similarly, non - value adding activities such as waiting for instructions, waiting for the materials, waiting for equipment and idle time of the workers are the common activities that are observed in the brickwork and reinforcement work. |
