Material consumption norms for various civil works
View attachment 2332
i have noticed in my experience quite a lot of engineers and supervisors are not aware of the material consumption norms for various civil activities. due to which the are not a position to place their requirements to the purchase departments resulting in project delay and materiel wastage's etc. in the following note i try my level best to enumerate the material consumption for various civil works for everyone knowledge.
The Following are the Quantity Of Materials Required for the Concrete Works Of Different Types all concrete consumption based on the nominal mix.
