Indonesian construction supply chains cost structure and factors: a case study of two projects
Abstract
Studies of Indonesian construction supply chains have been in the early stage. Previous studies have described very well the structures of construction project supply chains. Moreover, one of strategies that have been considered by construction companies for gaining a competitive advantage is to reduce the cost of their supply chains. The research's objective is to identify the cost structure of construction supply chains in Indonesia and factors that could influence it. By knowing these factors, construction companies are expected to be able to determine strategic efforts needed for reducing cost of their construction supply chains. Two construction projects operated by a large construction company were explored as case-studies. Rebar material was chosen for this supply chains study. It was found that the cost of purchasing was very significant. Meanwhile, costs of transportation and inventory were insignificant. It can be concluded that efforts to reduce supply chains cost by reducing costs of inventory and transportation would not be effective. Therefore, factors that could influence the cost of supply chains are related to management of supply chains, such as procurement policy, material requirement planning, supplier qualification, selection process, contract, and supplier development.
