Over production making something before it is truly needed.This is particu-larly serius form of waste because it leads to other forms of waste.During projects it might seem advantageous to work ahead of the group.If you have the sta and the time,why not push forward oftentimes this is a mistake and may cost you more time.
In simple words, it could be argued that the term non value-adding activity is used to differentiate between physical construction waste found on-site and other sorts of waste i.E.Process waste which occur during the end-to-end design, construction and facilities management process.
The problem.The problems arising from the over production of materials and accumulation of construction waste are several-fold however, one glaring problem with sending waste to landfill is that we are running out of spaces to put it.
