JIT is a cornerstone of Lean Construction, a compatilogy that focuses on maximizing value while minimizing waste. In civil incorporationg, waste include nott only physical materials but also houting time, rework, unnecesary movement, and unused talent. JIT helps eliminate houting by ensuring that the right t resources - labor, equipment, materials - arrive athe right place at thee right time.

Koordynacja wśród zainteresowanych stron

A civil engineering project involves many stakeholders: owners, designers, contractors, subcontractors, material suppliers, and regulatory bodies. JIT imposes strict coordination requirements. Daily or weekly "pull planning" sessions are common, where each party commits to what they will deliver and by when. This level of collaboration forces everyone to be accountable and to communicate early about potential bottlenecks. In practice, this has led to the adoption of tools like Last Planner System (LPS), which integrates JIT with collaborative scheduling. Engineers and project managers must constantly monitor progress and adjust plans in real time, creating a culture of adaptability and continuous improvement that drives innovative problem-solving on the ground.
