Technical Field
The invention belongs to the field of power distribution network engineering cost analysis, and particularly relates to a power distribution network engineering bill pricing method based on modular combination.
Background
According to the national Bidding method and the Bidding range and scale standard stipulation of engineering construction projects: in various engineering construction projects, the total investment of the project is less than 3000 million yuan RMB, and the investment of a single project is less than 400 million yuan RMB, so that the bidding can be avoided. In order to further strengthen project management and avoid audit risks, projects meeting the conditions can be tendered in a frame tendering mode.
At present, when a frame bid inviting list is compiled, the project amount lists of annual plan construction projects are all listed, the work load of compiling the bid inviting project amount list is large, the types are multiple, and a large number of repeated list items exist in compiling contents. Meanwhile, the material department takes a single project as granularity and requires each bidding unit to quote, so that the content is more and the space is large. Whether the bidding unit quotes and works or the evaluation expert reviews the works, the bidding unit quotes and works in a huge amount of data.
The bid-winning unit price of the frame bid guides construction work quotations of the projects all the year round, and the unreasonable design of the bid-winning engineering quantity list can leave unbalanced quotation utilization space for bidders, so that the province company is very passive in late project settlement. Therefore, the frame bidding engineering quantity list is difficult to compile and high in examination difficulty, and the skill imbalance quotation of the bidding unit is difficult to avoid, so that the manufacturing cost control difficulty is increased.

The transport distances are all set to 1 km.
Step 4, calculating the standard spot price of the modular list, which comprises the following steps: and establishing a standard list subdirectory of the low-voltage distribution area of the power distribution network project, and if the project item which cannot be covered is met, independently adding the list subdirectory.
And 5, establishing the electronic application tool for the network distribution engineering framework bidding, wherein the electronic application tool is a software tool which is suitable for the network distribution engineering framework bidding and bidding of 20kV or below in Liaoning province and is developed in a matched manner by utilizing a C + + development language, and the work of compiling the batch bidding and bidding of the list is realized.
The software increases the interconversion between the project budget and the list pricing file, and assists the development of the frame bidding work.
The invention has the following advantages and beneficial effects:
the invention relates to a power distribution network project list pricing method based on modular combination, which is mainly based on 'typical design of power distribution network project of national power grid company', 'budget quota of power distribution network project of 20kV and below' (2016 year edition) 'price-pricing regulation of power distribution network project list of 20kV and below in Liaoning province', and the like and is divided into 8 general modules such as earth and stone project, foundation project, pole and tower assembly, cross arm installation, stay wire installation, lead wire installation, on-pole equipment installation, low-voltage meter box installation and the like. Each general module divides sub-categories according to common work contents in actual engineering, selects characteristic values and finally determines the work contents of the inventory items and the characteristics of the inventory items, so that the bidding work efficiency of the power distribution network engineering framework of 20kV or below is further improved. The invention standardizes the construction cost pricing behaviors of 20kV and below power distribution network engineering bidding, bidding pricing, engineering settlement, construction cost analysis and list pricing modes, improves the accuracy and efficiency of price control compilation, and improves the working efficiency of the power distribution network engineering bidding.
