Lean Construction and Waste

Lean construction takes the concept of waste beyond materials and applies it to all activities on site.

Lean Construction & Waste

Eliminating waste is central to the whole concept of Lean construction. If something is not needed, it shouldn’t be there. If an action is not needed, it shouldn’t be done. Unnecessary things and unnecessary actions – waste in other words – cause delay and consume resources without adding any v

Similarly, things and actions which are necessary to add value should be there and should be done well. If they are not, the value they would have added or helped to add is going missing – in other words, more waste. Lean introduces the concept of 7 wastes within business which you can identify and then do something about. They are:

  1. Transport
  2. Inventory
  3. Movement
  4. Waiting
  5. Overproduction
  6. Over Processing
  7. Defects

Sometimes an 8th Waste is also included, ‘Skills’, which relates to not effectively using the skills and knowledge of employees available to do the work.

The different Wastes are often referred to by the acronym TIMWOOD(S).
