When calculating the cost of measures, the corresponding template cost cannot be calculated reasonably. Project characteristics are the premise of determining the comprehensive unit price. Because the characteristics of the bill of quantities project determine the substantive content of the engineering entity, it must directly determine the value of the engineering entity itself. Therefore, whether the characteristics of BOQ project can be accurately described is directly related to the determination of the comprehensive unit price of BOQ project.
For example, in the subgrade list, the materials used in the project elements only indicate ballast. By consulting the pre-tender estimate, the owner found that this material was priced according to ballast removal, so he thought that ballast removal should be used when performing the contract. However, according to the item "Materials are priced with mixed ballast" in the tender, the contractor thinks that if ballast is used, the unit price of this list should be adjusted at the time of settlement, which leads to disputes.
Project characteristics are the basis of fulfilling contractual obligations. The bill of quantities valuation is implemented, and the bill of quantities and its comprehensive unit price are part of the construction contract. Therefore, if the description of the project characteristics of the bill of quantities is unclear or even omitted or wrong, it will cause changes in the construction process, which will lead to differences and disputes.
For example, in a list of lime soil, the unit of measurement is M3, and the specific paving area or thickness is not described in the engineering characteristics, so it is difficult to determine the workload of multi-soil health care when pricing (the pricing stipulates that multi-soil health care is priced according to the top workload), thus causing disputes over the workload of multi-soil health care during the performance of the contract.
Extended data
The significance of the description of the project characteristics of the bill of quantities lies in:
1、? Item characteristics are the basis of distinguishing list items. The characteristic of bill of quantities is to express the substantive content of partial and itemized list items, and to distinguish specific list items under the same list item in the pricing specification. Without an accurate description of the project characteristics, it is impossible to distinguish the same or similar list project names.
2、? Project characteristics are the premise of determining the comprehensive unit price. Because the characteristics of the bill of quantities project determine the substantive content of the engineering entity project, it must directly determine the value of the engineering entity itself. Therefore, the accurate description of the characteristics of BOQ project is directly related to the accurate determination of the comprehensive unit price of BOQ project.
3、? Project characteristics are the basis of fulfilling contractual obligations. The bill of quantities and its comprehensive unit price are part of the construction contract. Therefore, if the description of the project characteristics of the bill of quantities is unclear or even omitted or wrong, which will cause changes in the construction process, it will cause differences and lead to entanglement.
