The construction industry in India faces significant issues, with 91% of projects delayed and 94% overrunning costs by 15%. Lean construction, inspired by the Toyota Production System, aims to minimize waste and optimize resource use, thus enhancing project value and efficiency. Key tools include value stream mapping and building information modeling, which collectively improve time, costs, and overall project quality.
Introduction to Lean Construction
- 2. The Horrible 90's Statistics… • 91 % of the projects in India Big and Small are delayed • 94 % of the projects in India are overrun in costs by 15% • 99% of the projects show low job satisfaction for employees • 92 % of first time customers don’t want to repeat the contractors/builders • 90% of people did not like the finished product – expectation vs reality Courtesy – i Talent - Nagpur
- 4. WASTAGES Basic Contents of work Anything beyond the absolute minimum Materials, Machines and Labor….. Is WASTE
- 5. EXAMPLES OF WASTE ● ● ● ● ● ● ● ● ● Poor Design Poor Constructability Poor Layout Excessive Staff Poor Procurement Lack of Flow of Work Lack of Co-ordination Poor Planning Inefficient processes ● ● ● ● ● ● ● ● Inefficiency in Machinery working Wastages of Materials Overrun in Time Overrun in Cost Adversarial Relationships Disputes Arbitration And so on……

- 9. DEFINITION LEAN CONSTRUCTION Lean construction is a “way to design production systems to minimize waste of materials, time, and effort in order to generate the maximum possible amount of value” (Koskela et al. 2002) Optimizing Efforts, Minimizing Costs and Time, Reducing Waste, Creating Value What Best Can be done, Should be done
