Abstract
Poor cost control management is a major issue that requires a comprehensive plan. A novel project management strategy for megaprojects is Learn Construction Management (LCM) theory, according to academics. This study investigates a Technology-Driven (TD) cost control approaches to reduce megaproject cost overruns in South Africa. PRISMA comprehensive literature reviews of prior publications were done. looking up suitable scholarly materials. After reviewing 87 items, we removed 26. The research examined whether LCM theory and Technology Driven (TD) theories, such as IoT, AI, and big data theory, could increase cost and schedule performance. Each theory/approach was thoroughly explained, technical differentiation concepts were explained, and pros and cons were weighed. Two proactive-corrective theories were discussed and applied to support megaprojects. The results demonstrated that LC and TD theory frameworks increased productivity, teamwork, and cost savings. The framework's theoretical and practical implications can inform construction management and project finance researchers' study and development.
