Resources are the most important part of any construction project. Total cost of project is based on resources. For India the construction industry has contributed an estimated6708billion to the national GDP in 2011-12 which is a share of around 8%. This sector is both labour and machine intensiveand provides employment to more than 35 million people, which is around 27% population of India. So, optimization of resources plays a vital role in saving of valuable natural resources and cost which is required to generate them. So, in this paper concept of optimization is understood clearly and try to implement it on bridge construction site. The case study is selected as Hyderabad metro project. In this project concreting of precast segment of bridge is considered. The main objective of study is to optimize the resource utilization on concreting activity by applying some operational research techniques such as transportation model, assignment model, EOQ etc. The paper also discussed the concept of multi agent negotiation used on site. Construction projects are unique in nature because construction activities are varies from project to project. Thus, it is not possible to apply result of optimization from any particular case study to any other construction site but the idea or technique regarding optimization till remains same for other sites.
