How to avoid ‘Downtime’ (waste of time) in (Industrialized) Construction

Avoiding downtime in industrialized construction (modular, prefabricated) requires a radically different approach to traditional construction, focused on synchronization, digital planning and supply chain management. Unlike the traditional construction site, the goal is to maximize efficiency in the controlled environment of the factory (off-site) and ensure accurate assembly on site (on-site). The key strategies to avoid downtime could be 1. Digital Planning and Design (BIM) or Production Management (Off-site) or Logistics and Just-in-Time Synchronization (JIT) or On-site Coordination. But perhaps Continuous Training and training personnel not only in safety, but in the handling of industrialized machinery and modular assembly, and Quality Control at Origin to inspect components within the factory to prevent undetected defects from causing serious stoppages in the on-site assembly stage are the fundamental key?
