Abstract

This paper presents a case study to discuss the application of Supply Chain Management (SCM) concept to the structural steel construction industry. The impact of scheduling and resources distribution were identified and examined by using the following methodologies: 1. Time Study and 2. Networking Simulation Models. Echelon I-steel-manufacturing phase: a simulation model has been developed based on the time study of steel beam fabrication in steel shop. This mock-up model can enables us to observe and study the different facets of its productivity, scheduled utilization, and production cost on different batch sizes. Echelon II-construction job site phase: a CYCLONE simulation model has been developed based on two precedent studies: the time study of beams and columns erection under this model, which is simulated for the entire erection process, and the assessment of productivity and production cost over each task. This study has shown the fact that the project of using the design-build (D/B) delivery process has obtained higher productivity and lower production cost than that of using the design-bid-build (D/B/B) delivery process.
