Jinnan Steel Group invested in the Quwo Group (a merger of two steel production plants) to optimize the plant’s industrial layout and achieve higher production quality, efficiency, and sustainability. As the general contractor, WISDRI faced technical and coordination challenges, compounded by limited space and a tight schedule amid COVID-19. They sought to streamline workflows and identify risks in advance through collaborative design and construction simulation technology.They selected ProjectWise and Bentley’s open modeling applications to digitally unify design among 16 different disciplines, reducing ambiguity and improving design quality. By performing collision detection, they eliminated 66 clashes, saving approximately CNY 1.7 million and reducing rework. Through construction simulation in SYNCHRO 4D, they cut construction by over 30 days and saved an additional CNY 3 million. The integrated digital approach minimized the impact of the pandemic and facilitated the development of a green, smart steel plant, promoting sustainable economic growth.
