Construction projects, particularly megaprojects, tend to frequently fail in satisfying their budget, schedule, quality, and safety objectives. Two of the most notable systems that have been developed to enhance project performance are the Last Planner® System and Location-Based Management System. This paper builds on combining these two systems through proposing an integrative production system that can play a significant role in enhancing project performance, especially in the case of megaprojects. The proposed production system incorporates five cohesive streams: production planning, material flow, Built in Quality (BIQ)/Information flow, tracking flow, and safety flow. This paper discusses each of these five streams, at five different implementation levels throughout the project lifecycle, in the context of an ongoing successful megaproject. Finally, the paper concludes by listing four main success pillars that are needed for the proposed production system to flourish.
