Time study was developed by Fedrick W. Taylor in about 1880 which is the first person to use stopwatch to study and measure work content with his purpose to define “a fair day work”. Motion study was developed by frank B. Gilbreth and his wife Lillian developed and redefied the motion study in 1909. The main advantage of T&M study is to simplify the necessary operations make the job easier by analyzing the process in the order to improve it through elimination of unnecessary operations, rearrange the sequence and layout of operations it may results in reducing the operating time. The method is use in time and motion study is to identify problems, choose the appropriate activity, plan the activity, record the information by relevant method, analyze activity factor develop economic method, measure work and standard time, define new efficient method and maintain new standard. In this research work the stop watch method is use to determine respective operation of construction activity of industrial building by physical observation. By time and motion study we can increase our productivity by 20% that means saving of resources.

Time study is direct and continuous observation of a task, using a time measurement devises or physical observation. The motion study was developed by Frank B. Gribreth and Lillain M. Gilbreth and consists of a wide variety of procedures for the description, systematic anlysis, and means of improving work methods. By the time being researches are carried out time and motion study to manage work by scientifically controlling. Industrial buildings have complex, unique and challenging construction work. The scope of work and change in design impact is average of 35%. all of those projects will have a major change issues regarding productivity, shortage of time and work efficiency. Growth of Infrastructure and industrial project have been a key part of the Indian construction, government increased its investment 20.9% from ฀ 4.9 trillion to ฀ 6.0 trillion. Statistics over the period have shown that compared to other sectors, this sector of economic activity generally creates 4.7 times increase in incomes and 7.76 times increase in employment generation potentially. By the time and motion study of industrial construction activity is done with physical observation, improve productivity and efficient work progress with desired quality. This research work is limited because big issue of global pandemic COVID-19 prevailing during the time of research. 1.1 NEED FOR STUDY To know stability of various construction activities in industrial building and to know wastage of resource and reduced by work standardization. 1.2 OBJECTIVE AND SCOPE The main objective of T&M study is to study planned time for each job which can be scientifically estimated. By the stop watch, calculate time required to complete the activity. To manage proper balancing of distribution of work. To develop efficient and standardized work method. The scope of the research work is limited to Ahmedabad city and to study construction activities on Industrial construction building with cost up to 100cr.
