Description
Technical Field
The invention relates to the technical field of engineering project management, in particular to a method and a system for analyzing engineering cost for reducing repeated workload.
Background
The construction project investment control is that each link of each stage of construction needs to compile corresponding cost files for investment control and cost management, wherein the influence of the design approximate calculation and the construction diagram budget on the cost management and the investment control of the construction project is the largest, therefore, the design approximate calculation and the construction diagram budget compiled by a design unit can be used as the basis of the investment control and the cost management after the examination of an industry management department, and the design approximate calculation of the construction project repetition is the highest limit of the investment control.
Construction projects (civil engineering and installation professions), municipal works, highway projects, waterway projects, railway projects, hydraulic projects, electric power projects, communication projects, aerospace projects and other different industries and professional projects can issue corresponding cost documentation methods and regulations, such as a national standard of construction project cost index classification and measurement standard (GB/51290) issued by the Ministry of housing and urban and rural construction, publication No. 1859, a road engineering construction project investment estimation compilation method (JTG3820-2018) and a road engineering construction project approximate calculation budget compilation method (JTG3830-2018) issued by the Ministry of transportation in 2018, and the cost documentation and examination work of the engineering projects must strictly follow the regulations of the cost documentation method of the industries.
Theory and practice of the road engineering physical quantity cost analysis method, "road traffic technology (applied technology edition), Luo xing Chun, etc., No. 4, 20160415, discloses (see pages 312-: the method for analyzing the cost of physical quantity is that firstly, reasonable items are carried out on the project or expected product to be analyzed for the cost (namely, scientific cognition and reasonable expression are carried out on the expected project), then the physical quantity (manpower, materials, mechanical machine shifts and the like) and the cost consumption of each item are analyzed and calculated, the unit price of each physical quantity in the current and local place is determined, then the physical quantity and the rate of each item are calculated, and finally the total cost of the expected project is summarized, and the general expression of the method is as follows:
the method for analyzing the construction cost of the project by the physical quantity construction cost analysis method solves four basic problems of ' what ' the project is dry ', ' how much the project is expensive ' and ' what fee '.
"what" means that an item table of the construction project cost is formed according to the design chart of the design file of the construction project to be compiled and the branch standard specified by the compiling method, and the work content and the branch level of the construction project are represented.
How to do is to group each sub-item according to the project table work content of the project, the sub-item hierarchy and the construction organization scheme, namely, the quota is set, and the work content of the project table sub-item must be consistent with the work of the quota table combination.
The term "price" refers to the unit price of the real resource analyzed according to the set of quota to determine the current and local budget, collect the current and local related documents and regulations (such as artificial wages, freight and vehicle and ship tax standards) and investigate the basic data such as price information and freight rate scheme.
The 'what fee' is the standard of what rate is selected, which rate is composed of which rate, the rate size, the budget calculation and budget can only be selected according to the specification, and the tender offer and tender base making are flexibly adjusted and determined according to the actual condition of the construction project.
The cost software system developed according to the physical cost analysis method has 'one file, two parameter, three items, four groups of price and five reports'. "five-step classic operation:
the first step is as follows: and one file, namely the construction project and engineering project file management.
The method mainly has the functions of creating, copying, pasting and deleting construction projects and engineering project files, and has the auxiliary functions of setting decimal point precision of main cost parameters, importing, exporting, backing up xml and excel format files, compiling descriptions, auditing descriptions, operating states and the like.
The second step is that: the "two parameters" are the "engineering parameters", "rate parameters" and "unit price parameters" of the set engineering project.
The 'project parameters', 'rate parameters' and 'unit price parameters' are set one by one for the project, and corresponding parameter files are imported and exported according to the xml format files.
And thirdly, adding project items and the number of the project items.
Adding project items according to three modes of standard library import, excel import, complete item number input and the like.
The fourth step: "four sets of prices", i.e. determining the cost components for each calculation section.
Calculating the sub-items according to one of five modes of quota list, formula list, expense list, input unit price and input amount to make group price.
(5) And the five reports are corresponding to the previewing and printing of the reports.
The compiling and the checking of the construction project cost file can be completed through the five steps.
At present, the method and the system for analyzing the physical quantity cost use engineering projects as operation objects, and corresponding cost documentation methods and regulations for releasing in different industries and professions are that the cost documentation is firstly carried out on the engineering projects, and then the total amount and the total physical quantity of the construction projects are obtained by summarizing the amount and the physical consumption of the engineering projects. For the construction projects needing to compile cost files in a segmented and distributed manner, only one construction project compiling cost file is needed, and the repeated workload is large; in the compiling process, errors caused by misoperation such as decimal point input errors or unit conversion and the like are difficult to find in time due to the number of the sub-items and the quota, and the checking workload is large.
