Description
Technical Field
The invention relates to the technical field of railway engineering pricing, in particular to a pricing method and a pricing system suitable for railway engineering.
Background
Prior art foundation
The EBS (Engineering entity decomposition) divides the Engineering entity according to the minimum construction, and comprises an IFD (Engineering face definition) code, an EBS (Engineering entity decomposition) Structure code and an Engineering entity decomposition system of construction design basic information (such as pile length, pile diameter, concrete masonry square and the number of reinforcing steel bars). The BIM alliance of railways has released 'the guide of decomposition of the entity structure of railway engineering', and provides basic data of the decomposition of the engineering entity for the verification of engineering pricing.
The WBS (Work Breakdown Down Structure) comprises a WBS Structure code, a subsection and an associated check batch and an engineering task Breakdown system of a construction record table in order to realize engineering functions or complete Work tasks which need to be completed in sequence by entity construction. 2018, the construction quality acceptance standard of each specialty, and provides basic data information for subsection and itemized inspection lots and construction record tables.
The Qlist (Bill of qualites List) is a document compiled by the tenderer under unified rules with the respective construction experience, skill and project management levels, and the relevant information of the investigation. And the engineering list system comprises Qlist structure codes, engineering characteristics, operation contents, engineering total amount and unit price. The State railway administration published the Specification of railway engineering volume List in 2018.
Existing project pricing method
The checking and pricing refers to the general name of checking and accepting the qualified project quantity or work in the construction process, metering, checking and accepting, and metering the project quantity or work, and is the basis for handling the settlement of the project price. The railway engineering project has the characteristics of large scale, long construction period, complex geological conditions, more engineering specialties, large investment, more factors influencing cost control and the like, and the labor checking and pricing are key links of contract management and engineering cost control and are highly valued by all units. The method has the advantages that the labor checking and pricing work is standardized, the labor checking and pricing management of engineering projects is enhanced, the engineering construction cost can be reasonably controlled, and the production progress and quality control can be effectively promoted.
At present, a project quantity list (Qlist) pricing mode is generally adopted in railway engineering, the main core of the method is that the project quantity is provided by bidders, and each bidder carries out independent quotation by combining respective construction experience, technology and project management level under unified rules and relevant information of research. The main work flow of the current work verification and pricing is as follows: firstly, technicians at each work point of a construction unit count the field finished real object project amount in the pricing period, and report the calculated amount to a project planning part after the calculation is finished. The planning part converts the field real object engineering quantity into the work content of an engineering quantity list, compiles a verification pricing list and an application form, and reports to the master after the project responsible person signs and confirms. After receiving the application of the check-up pricing, the master supervision office audits the work content of each work point in the check-up pricing list by a supervision engineer, mainly audits whether the content object is completed or not and whether the data such as the check batch are complete or not, and confirms the signature and reports to the master supervision office after the audit is completed. And the chief supervision department carries out approval and reports to the construction unit for verification after the verification is correct. At present, the price-counting work of the validators mainly adopts manual statistics, compilation and calculation or adopts single software to compile the price-counting list of the validators.
The existing project pricing defect
The phenomena of virtual work inspection and over work inspection are frequently prohibited.
According to the file specification of a railway construction project inspection pricing method, the inspection pricing is subject to legal and honest principles, the prior labor and the later pricing are carried out according to a specified program, and the false inspection pricing is forbidden; the 'railway basic construction fund management method' stipulates that the fact that the price of the construction worker needs to be checked is that the construction unit and the supervision unit check and verify the price table of the construction worker compiled by the construction unit, and the overestimation of the common test, the preliminary test and the virtual test is forbidden. In the actual work, some units can complete the assessment target, and the construction units and the related working personnel of the supervision units can perform virtual inspection and over inspection through various means. The excessive inspection of the virtual inspection worker causes the inspection quantity to exceed the original design or contract qualification quantity, the project payment is paid in advance, the contract is not performed seriously by the contract organization, the residual project is difficult to advance, and the adverse effect of the sharp increase of the project cost is caused.
The efficiency of the work of checking and pricing is low.
The existing manual counting, compiling and calculating the work efficiency of the experimenter pricing list is low, firstly, the efficiency is not high when each work point technician counts the completion condition of material objects one by one, secondly, the plan department worker converts the construction material objects one by one into the work content of the engineering quantity list, and a pile of a bridge is used as a column, firstly, the bridge is required to be determined to check a grand bridge, a large bridge or a medium-small bridge, and the bridge is also required to be determined to be a complex grand bridge or a common grand bridge, and after the information is determined, the pile is required to be on the ground or on the water through turning over a drawing, and the pile diameter, the pile length and other information. And the supervision project check is to check the data of the inspection lot and the like one by one, so that the working efficiency is low and the time consumption is long.
The inspection pricing monitoring mechanism is deficient.
The scale of the project in the railway project is large, the contract amount of one construction standard section is generally twenty to thirty billion, and the construction length can also reach twenty kilometers to forty kilometers. Therefore, the supervision engineer and the construction unit are not enough to know the site by the experimenter and the charge person. Therefore, after the on-site supervision engineer checks, the chief engineer and the construction unit can directly sign the signature and do not check the signature; and secondly, even if the construction unit and the supervision unit check the project quantity on site, most of the time, the construction unit and the supervision unit walk on site to pass the site, and the auditing function cannot be really realized. And the virtual inspection and the over inspection during the evaluation work of the inspection occur. And because the paper edition of the pricing information of the verification can not form the work of information sharing, only a planning part and part of leaders for mastering pricing content in the pricing work of the verification are provided, and a transparent supervision mechanism and means are lacked to ensure that the pricing work of the verification is reasonably carried out in compliance.
The capacity of planning personnel of a construction unit needs to be improved integrally.
Along with the increase of railway construction projects year by year, along with the loss of talents of construction units, even technicians who are not in the past for one year are responsible for the work of checking and pricing, and due to the lack of construction common sense and experience, errors of parameters related to a project amount list, errors of data logic relations and the like occur during the filling of a work-piece checking and pricing table. The business personnel lack the reasons of inaccurate construction general knowledge engineering quantity verification, unreal report data, untight working procedure and the like, so that the project cost management is disordered. Serious hidden danger is buried for project cost management.
Therefore, in order to solve the defects in the conventional checking pricing, a pricing method and a pricing system which can improve the pricing efficiency and realize automatic one-key completion and are suitable for railway engineering are needed.
