This study systematically elaborates on the core connotation and implementation pathways of the intelligent construction system from the contractors’ perspective. It analyzes a digitally-driven intelligent construction framework and proposes replicable and scalable systematic solutions for intelligent construction in practical engineering projects. Furthermore, by integrating theory with practice, it validates the significant effectiveness of intelligent construction systems in enhancing efficiency, optimizing management, and mitigating risks. It can provide a reference for industry transformation and upgrading, promote the deep integration of intelligent construction technologies with engineering practices, and ultimately support the achievement of high-quality project delivery and whole-lifecycle value enhancement.
