Power transmission line project feasibility research and design integrated bid invitation price limit calculation method

Abstract

The invention provides a power transmission line project feasibility research and design integrated bid invitation and price limit calculation method, and belongs to the technical field of power grid project construction. The method comprises the following steps: S1, acquiring key parameters of a power transmission line project to be bid invitation, wherein the key parameters comprise a voltage grade, a loop number, a path length and a technical scheme; S2, calculating the total project investment according to the reference price; S3, obtaining the project cost of the line body; S4, obtaining a bid invitation price limit of the bid invitation project, wherein the bid invitation price limit comprises a research compilation fee, a reconnaissance fee and a design fee; and S5, verifying the calculated bid invitation price limit. According to the method, the feasibility research and initial setting integrated bid invitation price limit can be directly calculated, the method can be applied to bid invitation work of the power transmission line project, scientific and reasonable fund distribution can be ensured, the investment efficiency of the power transmission line project is improved, and economic benefits and social benefits are improved.

Description

technical field [0001] The invention belongs to the technical field of power grid engineering construction, and in particular relates to a price limit calculation method for integrated bidding and design of transmission line engineering. Background technique [0002] In the traditional engineering survey and design bidding mode, the feasibility study in the preliminary work of the project does not belong to the category of mandatory bidding, and the preliminary design, construction drawing design, and completion drawing preparation of the later stage of the project are carried out on the basis of the preliminary feasibility study. Public bidding . In the traditional mode, the pre-feasibility study and post-design may be completed by different units, and the workload between the two units is relatively large. The winning bidder for the post-design does not have a deep understanding of the pre-work of the project, which may affect the design progress and coordination. quality...
