The document discusses the Just-In-Time (JIT) technique for materials management. It describes JIT as a philosophy of manufacturing that aims to eliminate waste and continuously improve productivity by receiving materials at the right quantity, condition, place and time for production. The key principles of JIT include total quality management, production management, supplier management and inventory management. The document also outlines some benefits of JIT, such as reduced inventory and costs, as well as challenges, and recommends that buffer stocks be maintained when implementing JIT in construction to avoid delays from disrupted supply.

2. Material management
 The process of management
 Planning
 Organizing
 Controlling
 Flow of materials
2

3. Necessity
 In any construction work
 Materials contributes 60 – 65 % of total value of the project
 About 10- 20 % of the delivery is the wastage
 Reduction of cost
 Without compromising quality
 Involves inventory

4. 6 basics of material management
 Plannig
 Designing
 Procurement
 Vendor control
 Construction
 Closeout

of planned eliminations of wastages and
continuous improvement of productivity…

7. History of JIT
 Evolved in Japan
 Toyoto motar company , 1970.
 Most efficient use of limited resources
 Optimal cost/Quality relationship
7

8. Philosophy
 Inventory takes up space and ties down capital
 In the JIT philosophy, raw materials are not stockpiled.
 right quantities
 in the right condition
 to the right place
 and at the right time for production

10. Do’ in JIT
❖ Eliminates waste .
❖ Achieves streamlined production .
❖ Eliminate disruptions in production … caused by poor quality,
schedule changes, late deliveries.
❖ Makes the manufacturing delivery system flexible by allowing it to
handle a variety of products and changes in the level of output.
❖ Reduces setup and delivery times .
10

11. Principles of JIT
❖ Total quality Management
❖ Production Management
❖ Supplier Management
❖ Inventory Management
❖ Human Resource Management

12. survey
 32 contractors were surveyed
 Few questions asked
 Answers we got from the survey we come on a conclusion

13. Buffer stocks13

14. Top management commitment and
employee involvement
 Continuous improvement process
 Disciplined and correct operations
 Involvement in improving current work processes
 Motivation and efforts
14

15. Elimination of wastes
 Waste is anything that do not add any value to final product
 Excess inventory
 Stockpiling inventory
 Waiting time
 Rectification and correction of defects
 Getting things done “First time right” is JIT

17. Total quality control
 Acceptance of good quality material
 Rejection of material affects grievously
 Disruption of all work flow and schedule
 Wiped out all savings due to JIT
17

18. Single sourcing
 Only single source of supplier
 Lesser time for ordering
 Too many dealers creates confusion
 Time taken is more for ordering
 Single source good for long business perspective

20. Storage issues
 Space constraints
 Duration of storage
 Movement of resources
 Safety measures
20

21. Buffer stocks
 Harsh condition
 Late deliveries
 Safe storage stock
 Work flow must not be disrupted
21

22. Factors for storage constraints22

24. When inventory is less24

25. Transportation
 Long trucks , trailers accumulate space
 Stuck into traffic
 Late deliveries
 More deliveries at a time
 Bad weather
25

26. Actions to be taken
 Send a letter of complaint to the pre-caster
 Learn from lesson and take preventive measures
 Impose penalty charges on the pre-caster
 Reprimand the pre-caster and then let the matter rest
 Simply ‘‘give-and-take’’ to avoid any sour relationships
26

27. Advantages of JIT
❖ Reduced Inventory
❖ Improved quality
❖ Lower costs
❖ Reduced space requirements
❖ Shorter lead-time
❖ Increased productivity
❖ Improved vendor relations
27

28. Disadvantages of JIT
❖ Danger of disrupted production due to non-arrival of supplies.
❖ Danger of lost sales.
❖ High dependence on suppliers.
❖ Less time for quality control on arrival of materials.
❖ Increased ordering and admin costs.
❖ May lose bulk-buying discounts
28

29. Recommendations
 Not possible to apply full JIT approach in India
 Buffer stocks should be there so that the work will not be delayed
 Slow improving process
 Training is required
 Small lot size should be implemented
29

30. Benefits of Small Lot Sizes
Reduced Inventory
Less Rework
Less Storage Space
Problems are more apparent
Increase Product Flexibility
Easier to balance operation
30

31. Conclusion
 JIT if implemented properly can be proved as best technique
 Improvement in construction industry is necessary
 Wastages becomes very low in JIT hence it’s implementation can
generate higher profits
 Very trained experienced people are required for implementing JIT
