Lean Construction is maturing in Costa Rica. Repetitive projects respond best (vertical residential, industrial buildings, retail rollouts) where takt time and standardized work yield 8–15% schedule savings.
It still struggles with small subcontractors lacking planning culture, and projects with frequent scope changes (where the Lean flow breaks).
Highest-leverage tool is Last Planner System® at weekly planning level: it raises the percentage of activities completed on time (PPC) from the typical 50–60% in traditional projects to 80–85%.
