The improvement of construction systems and management systems do not move together in construction industry, not using the effective management approaches decrease the productivity of the work. The firms both in national and international area in manufacturing industry use supply chain management to preserve their competitive force.
As material costs account for a high percentage of the overall cost, the success of a project is heavily dependent on material related factors and processes. In Turkey because of extensively using in-situ concrete in construction, the supply chain for reinforcement and concrete is very important. One of the components of concrete is &ldquo / re-bar&rdquo / and its supply chain, rbSC (rebar supply chain) was investigated within the scope of this research.
In this study a framework was developed on the basis of the information from a literature survey and a field-test consisting of face-to-face interviews and questionnaire to determine the factors affecting the rbSC externally and those related to the supply chain participants. The developed rbSC performance framework was analyzed with Structural Equation Modeling rules. LISREL software was used, and the outputs of LISREL were evaluated by relationing with the information obtained from literature survey. The developed framework can be used to maximize both effectiveness of the rbSC process and efficiency of time and cost related issues in the rbSC. rbSC performance was associated with the project performance at the end of the study to reach a higher-level scale.
The difference between the performance ratings obtained by self-assessment of a participant and those obtained through assessment done by the others was used to determine the affects of cultural issues on performance. Common reasons for the lower performance were analyzed due to cultural context and recommendations were set down for rbSC participants to solve the problems.
