The focus of the dispute between the two parties is on the amount of concrete. The key is how to use the value of the reference amount of concrete to go to the top. Now there are two commonly used benchmarks. The first is based on the theoretical volume calculation of the construction drawings, which is the so-called settlement by drawing. The second is based on the calculation of the concrete company's volume of supply volume, which is the so-called shipping ticket settlement. These two different methods for calculating the amount of squares each have their own drawbacks, thus causing uncertainty in the determination of the actual amount of data.

First, according to the theoretical basis of the volume of calculation of the construction drawings

This method is beneficial to the demand side and unfavorable to the supply side. The construction unit has professional technicians to calculate the volume of the components, and the concrete mixing station will not configure the corresponding professionals to do the drawing calculations. In addition, the changed part of the drawings may not be counted, and it is not excluded that the construction unit intends to conceal it. According to the calculation of the amount of drawings, it should also be based on the as-built drawing, but the drawing of the Yuan Yuan lags behind the supply of concrete, and the operability is poor.

Second, according to the amount of volume calculated by the supplier of concrete mixing station records

This method is favorable to the supplier and unfavorable to the demander. The concrete mixing station uses the mixer truck as the supplier unit. Each vehicle carries a delivery order with the above indicated amount. Actually, the delivery truck is loaded with this value. In accordance with the concrete, the person responsible for signing at the construction unit has no way of knowing. If the concrete mixing plant wants to deliberately lose money, it is easy to do. ?
