Abstract:This paper addresses the implementation bottlenecks of engineering digital delivery faced by traditional industries during their digital transformation, particularly the challenges of standardization gaps and entrenched mindsets. Commencing with the fundamental concepts, it provides a systematic overview of digital delivery, covering its content, standards and basis, advantages, processes, management, platform and functional requirements, and associated challenges. The study then focuses on an analysis of its application within the non-ferrous metallurgy industry. The research concludes that digital delivery is a critical component in the construction of smart factories. It enables a forward-looking approach to digital factory construction that originates from the design phase, thereby enhancing the level of engineering digitalization, improving construction quality, and reducing costs. Furthermore, it establishes a solid digital foundation for factory operations and maintenance (O&M) and future smart factory initiatives, underscoring the profound significance of concurrently implementing digital delivery during the engineering construction phase.
