Implementation model for residential housing works in Cuba applying the Lean Construction philosophy

This study explores the application of Lean Construction as a strategy to enhance productivity in the construction industry. A case study of “52 homes in the Roble neighborhood” revealed that only 45% of working time is dedicated to productive tasks, while 35% is contributive and 19.5% non-contributive. The main causes of inefficiency include poor planning, ineffective communication, disorganized job sites, inconsistent material supply, and transportation issues impacting worker attendance. A detailed analysis of key Lean tools and their implementation methodologies is presented, identifying specific opportunities for improvement. In response, an experimental Lean implementation model is developed to guide professionals and companies in adopting these practices. The findings aim to promote broader integration of Lean Construction principles across the sector to address such inefficiencies and improve overall performance
