7. Conclusion and Recommendation

7.2. Recommendation

It has been more than two decades that the concept of LC has been introduced in the construction industry. But, still, the idea of LC implementation is very limited in the construction industry, although LC has shown positive results in reducing wastes in the construction process through the application of various LC tools. Considering the benefits of LC tools implementation related to the elimination of waste in the process, enhancing transparency, and barriers to implementation of LC in the industry, some of the recommendations are suggested. These recommendations according to the author, will not only reduce wastes in the process but will enhance transparency and

show objective results on construction projects and also helps in the implementation of LC in the industry.

1. Measurable indicators of the performance improvement with visual management technique.

2. Visualization of the stream is required to identify the wastes in the process.

3. Increase transparency on the construction site by visualizing the responsibilities and the information.

4. Senior management needs to more inclined toward the implementation of LC tools on projects.

5. Proper training and skills development of the workforce on site about LC.

6. 5’s technique needs to practice on site.

7. Prototyping of the task or activity should be done to quickly understand the whole process.

8. The standardization technique needs to implement on-site to avoid the unnecessary movements of the workforce and to enhance safety.

9. Last Planner System (LPS) need to be implemented to visualize the progress of the projects.

10. “5 Why” tools should be implemented to identify the root causes of waste and problems on the construction site.

11. Further research is required for the implementation of VM on construction and finds the measurable benefits and more reliable results of VM implementation.

12. Lean Project Delivery System (LPDS) should be implemented on construction projects to identify the benefits of LC from the early phase of the projects.

13. The national culture of LC implementation is required to adopt for LC implementation in the specified countries.

14. Further research work and LC development institutes are required to establish for the implementation of LC in the construction industry.

15. Implementation of the LC principle should be included in the contracts to make it necessary to implement LC.
