Reference Rate

DDC have to make cost estimate for construction of trail bridges based on district rates of materials and labors. In case of steel parts and galvanization, raw materials are not available at districts and steel parts are not manufactured at districts but at industrial centers. Therefore, the rates of raw materials for steel parts and galvanization should be uniform in all districts. The extra cost due to remoteness of the districts or bridge sites is covered by the transportation cost and is different item.

For this purpose, quotations were collected from different Rolling Mills, Suppliers and Traders for the following materials and accordingly rates are established as below."
