materials end up as waste on construction sites. It is reported that construction waste constitutes 26% of the total amount of waste produced in the Netherlands and 29% of the solid-waste stream in the USA [1]. About one third of the waste contribution is done by construction industries, wherein these materials add to the cost of the project.

Calculating the weight of steel based on the sample unit weight is necessary to avoid manipulation by the Supplier. This actual weight of steel is required for the periodical Reconciliation of Steel. Say, for example. 100 MT of 16mm Ø bars of Fe500 grade are required to procure. Assume the weight of bar received is 1.63 kg/Rm.
