Description

Technical Field

[0001] The present invention belongs to the technical field of engineering cost, and in particular relates to a construction method and system for an automatic calculation model of engineering cost. Background Art

[0002] Project cost includes two parts: cost compilation and whole-process cost management. The work content of cost compilation is to calculate the theoretical investment price based on the design results and pricing basis. The project cost results are often used in project investment management and risk assessment. For construction projects, cost evaluation is required in the competitive bidding and quotation stage, macro site selection stage, preliminary project establishment, feasibility study stage, and preliminary design stage to calculate the project's financial rate of return. Cost evaluation is carried out in the purchase price negotiation stage to determine whether the quotation is reasonable. Therefore, a calculation model with good applicability is usually used to output the project cost to facilitate project evaluation.

[0003] In the current existing technology, it is necessary to calculate quantities based on two-dimensional drawings. However, there are many types of quantities to be calculated, and the rules are changeable, which makes it easy to miss items and make mistakes during calculations. At the same time, when calculating quantities, quotas are usually applied manually, and quotas, equipment, and materials are manually selected and applied item by item from the quota library. Then, according to the engineering quantity table, computer cost software is used to automatically calculate the costs.

[0004] The existing technology of manually operating engineering costs not only increases labor costs and time costs, but is also prone to manual selection errors, resulting in low matching selection efficiency and accuracy, making it inconvenient to conduct a true evaluation of the project.

[0041] When the construction method provided by the present invention is used, first, a demand analysis is conducted for different project types and investment compilation requirements, including analysis of pricing models and key factors for different types of housing construction such as concrete frame structures and steel structures, and analysis of key factors for different types of housing construction investments; then, the cross-reference relationship between the construction quota system and the bill of quantities is analyzed, the unique identification of quota matching is determined, a logical network system is constructed, and in combination with the needs of the housing construction project, the corresponding construction quota content is studied and analyzed, and in combination with the bill of quantities, the cross-reference relationship between them is sorted out one by one, multiple key factors are determined, and the unique identification factors of the bill of quantities matching quota are further identified, and a logical network system is constructed; based on the unique identification factors of the bill of quantities, professional collaboration is carried out to design the content of the mutual reference sheet, and to unify and solidify it; based on the construction of an automated cost calculation model and the writing of Application instructions: Based on the logical network system of input indicators (mutual information sheets) and output indicators (matching quotas), and in combination with the budget preparation and calculation regulations for power grid project construction, edit the calculation formula, build a model through Excel, and write application instructions and preliminary user guides; based on the Java platform, general database, and web-based CS system platform, develop supporting software for technical support development, which can quickly process mutual information handover sheets through embedded formulas, automatically generate cost system tables, and integrate relevant data into the software system; construct an indicator comparison module in the software, and construct major technical and economic indicators such as square meter cost, steel consumption, concrete consumption, steel bar consumption, and wall panel type in the software, select data from the database to achieve horizontal and vertical multi-dimensional comparison; use the developed software in actual projects, analyze its applicability, and add or modify functional modules according to project requirements.

[0042] like Figure 1 and Figure 3 As shown, the demand analysis in S1 includes analyzing the pricing models of different types of housing construction such as concrete frame structures and steel structures; analyzing the key factors of different types of concrete frame structures and steel structures; and analyzing the key factors of different types of housing construction investments.

[0043] The demand analysis provided by the present invention starts from the following aspects when used:

[0044] Project type identification: First, clarify the specific type of project, such as wind power project, construction project, etc., as well as the scale and complexity of the project, to provide a basis for subsequent investment preparation;

[0045] Sorting out investment preparation requirements: Detailed sorting out the investment preparation requirements at different stages of the project, including decision-making, design, construction preparation, construction phase, and project operation and maintenance phase, to ensure the accuracy and rationality of the investment estimate;
