In the management system, it is necessary to further subdivide the contract bill of quantities according to the engineering part when checking the list, as shown in Figure 2- 13. The bridge engineering in the bill of quantities in Chapter 400th can be divided into concrete bridges first, and then further subdivided according to the structure and parts, until each pile, beam, etc. A list of a heap is displayed on the right. Then the system automatically generates the contract bill of quantities according to the itemized list, which is convenient for measurement, payment, change, settlement and project investment control in the construction process.
Double-click the bill of quantities on the right interface above to display the detailed information of the bill, including calculation formula and drawing number. Click on the drawing number to directly view the corresponding electronic AUTOCAD construction design drawings, which greatly facilitates the management personnel at all levels to review the engineering quantity in the business of bill of quantities verification, measurement payment and engineering change, as shown in Figure 2- 14.

Jingying Expressway Project Office immediately organized the construction unit, supervision unit, technical personnel of software company and contract survey engineer of the project office to get together to check the list after the construction unit entered the site. First, the contract measurement engineer of the project office determines the principle of splitting the bill of quantities of subgrade, bridge and culvert, pavement and greening, and to what extent. Then, the contractor's survey engineer will input the quantities of each part into the system according to the construction design drawings, which will be checked and signed by the senior survey engineer. Finally, the contract survey engineer of the project office will review and sign in the system. After the bill of quantities is incorporated into the system, it is not allowed to be modified as the basis for engineering measurement and payment, engineering change and final accounts.
