Ready mixed concrete (RMC) is the prime material required for buildings and Government & Non-Government infrastructure work, and it is exponentially growing industry in India. RMC is produced to meet client’s/customer’s requirements and its deliveries must be conventional to construction site. Therefore, due to technological operating constraints – the material cannot be prepared in advance and stored. To operate effectively the concrete production scheduling & truck dispatching are always handled by experienced staffs. This paper represents the constructive and unconstructive impacts due to geographical, political and regulatory differences. Also, various other factor like controlled and uncontrolled delays which occurs during preparation, transportation and utilization of RMC plants in India. Also, paper focuses on delay factors effecting batching plant by with stochastic mathematical models. The main objectives are (1) Identifying the sources of delay in concrete batching plant (CBP) (2) assessing their impact on production, time, cost and efficiency (3) how each factor can affect the rate cost of CBP in unit price. Researched data were collected for different batching plant sites to verify the designated model.
