Building material cost accounts for about 65% of the engineering cost, and some even reach more than 75% in the current formation of the construction installation engineering cost in our country, so the price of materials determines the engineering cost to a great extent.
It is essential for proprietor to master the price fluctuations of building materials to control engineering cost, and it is also important for contractor to determine the bid price.
Building material cost accounts for about 65% of the engineering cost in the current formation of the construction installation engineering cost, and the proportion has a rising trend.
These data show that materials is in a obviously dominant position in the fabrication of engineering cost, Therefore, it is especially important to grasp the building materials price information accurately.
Determine the engineering material price is beneficial to increase investment returns [4].
