[0079] The method disclosed in the present invention is further explained below with reference to the embodiments.

[0080] Unit engineering decomposition and definition are the key links in the implementation and application of the entire quality control and management subsystem, and are also important steps in implementing standardized construction management. Unit engineering decomposition first decomposes the project into unit engineering, sub-projects, sub-projects, and unit engineering based on the contract. The decomposed sub-projects are comprehensively managed using 9-digit codes. Unit engineering decomposition codes will be used in the construction process detection, construction material detection, test piece detection, quality accident management, and project acceptance and evaluation modules to determine the implementation and management objects of each module. Unit engineering decomposition should fully reflect the principles of standardized management of engineering construction. In the early data preparation stage, full demonstration and analysis should be made to ensure the correctness and rationality of unit engineering decomposition during implementation. Once the unit engineering decomposition is referenced in other modules of the quality control and management subsystem, it cannot be modified or deleted due to data constraints. At the same time, the unit engineering decomposition code does not have the ability to update, and the integrity and correctness of the data entering the database should be guaranteed. Therefore, the unit engineering decomposition code should be maintained by a dedicated person, and the data should be carefully verified and reviewed before data organization and entry, and organized and implemented as a standard.

[0081] Step 1: Unit project decomposition and definition. The quality management personnel of the construction unit shall complete the division of unit projects, sub-projects, sub-items and unit projects and the definition of unit projects in D8501 and D8502 of the TGPMS system according to the construction organization design of the project. This is the basis for project quality management; including:

[0082] (1) Enter the D8501 screen to decompose the unit project. First, enter the unit project. The unit project is a 1-digit organization with a code of 1. (2) Under the unit project, enter the sub-project. The distribution project is a 2-digit organization plus the unit project 1-digit organization. The code is 101. (3) Under the sub-project, enter the sub-project. The sub-project is a 2-digit organization plus the unit project 1-digit organization. The code is 10101. (4) Enter the unit project under the sub-project. (5) Enter the D8502 screen to define the above unit project. The unit type is defined as: ordinary concrete pouring. (6) Save the file to complete the decomposition and definition of the unit project.

[0083] Step 2: Establish the inspection standards for construction process. The quality inspection standards are the core of quality site management, including: inspection standards for construction process and inspection standards for materials and test pieces. The inspection standards for construction process are determined by the construction unit, and the owner's quality and safety department is generally responsible for the data maintenance of daily inspection standards. The owner's quality management personnel maintain the inspection standards for the process through the D8512 screen.

[0084] Step 3: Construction process inspection. The on-site process inspection is conducted by the supervision unit. The supervision unit conducts detailed inspections on each process according to the different construction types of the construction unit. The inspection standards refer to the process inspection standards of the owner's supervision. The supervision unit compares the inspection standard value and the actual inspection value to make a clear judgment on the process quality of the construction unit. The process inspection is conducted by the on-site supervision personnel of the supervision unit through the D8510 and D8511 screens. The process includes: (1) entering the D8512 process inspection index screen to input the formwork installation process of the ordinary concrete pouring construction type, and establishing the inspection index of the formwork installation process; (2) entering the D8510 process inspection screen to input the inspection form of the formwork installation process, and selecting the unit project to be inspected: contract code 0101029, unit project 101010001; (3) navigating from the D8510 process inspection screen to the D8511 process inspection detail screen, and establishing the association between the unit project and the construction type through the unit project definition screen. The process inspection index under the construction type will be automatically displayed in the D8511 screen, and the inspection personnel will conduct process indicator inspection item by item according to the process inspection index;

[0085] Step 4: Establish material testing standards. The owner's quality and safety department will classify and organize the main materials involved in the project, and subdivide them according to major categories, types, and specifications, and enter them into the system through the D8521 screen. The owner's quality and safety department will establish material testing indicators based on major material categories and enter them into the system through the D8522 screen. The owner's quality and safety department will establish testing standards for various material specifications based on material specifications and models and material testing indicators, and enter them into the system through the D8508 screen.

[0086] Step 5: Construction material testing. Material testing is completed by the material supervisor of the supervision unit or an external material testing center. The supervision unit compares the material testing standards and actual test values ​​one by one according to the material testing standards established by the owner, determines whether the materials are qualified and the grade, and enters the data into the system through the D8506 and D8523 screens. Finally, the material and test specimen testing is registered through D8509. It includes: (1) Enter the D8521 material and test specimen coding maintenance screen to enter the material category; (2) Enter the variety under the steel bar (wire, bar) category; (3) Enter the specification under the hot-rolled ribbed steel bar II (RL335) variety; (4) Enter the D8522 material test specimen testing index screen to establish the testing index of the material category steel bar (wire, bar). Note: Material testing index is established according to the material category. The testing index for different material specifications is the same, but the material testing standard for each material specification is different. (5) Enter the D8508 material and test piece inspection index standard screen, and establish the inspection standard for hot-rolled ribbed steel bar II (RL343) Φ32 material; (6) Enter the D8506 material and test piece inspection screen, and input a test sheet for hot-rolled ribbed steel bar II (RL343) Φ32 material; (7) Navigate from the D8506 material and test piece inspection screen to the D8523 material inspection details screen, and perform actual inspection of hot-rolled ribbed steel bar II (RL343) Φ32 material according to the material inspection standard. (8) Enter the D8509 material and test piece inspection registration screen, associate the inspection number: 0718-1 with the 302 sub-project of the 0103026 contract, and perform material inspection registration. (9) Save, exit, and complete the material inspection;

[0087] Step 6: Identify the quality problems of the construction project. The quality problems are managed by the on-site supervisor of the supervision unit. The on-site supervisor records the quality problems found on site through project quality inspection and other means, and enters them into the system through the D8515 screen. Including: (1) Enter the D8515 quality problem screen PAGE1 quality report review information; (2) Enter PAGE2 quality problem processing information; (3) Save and exit;

[0088] Step 7: Obtain the code of each unit distribution item, and calculate the EBS project code using the first calculation formula; extract the identity ID corresponding to each project code when it is generated, and calculate the comprehensive code using the second calculation formula; calculate the quality problem index and safety problem index of the project according to the comprehensive code using the third calculation formula;

[0089] The first calculation formula is:

[0090] The first calculation formula includes:

[0091]

[0092] Where, Be is the EBS project code; n is the total number of sub-items; i is the sequence number of the sub-item; Fi is the code of the i-th sub-item; H is the preset classification interval;

[0093] The second calculation formula includes:

[0094] Z id =H n +1BID+Be

[0095] Among them, BID is the identity ID; Zid is the comprehensive code;

[0096] The third calculation formula includes:

[0097]

[0098] Among them, A is the quality problem index of the project; B is the safety problem index; Y(·) is the function of taking the remainder; s1 is the safety problem margin; s2 is the quality problem margin.

[0099] Step 8: Project quality assessment and acceptance. Quality assessment and acceptance are important aspects of quality management. All engineering projects must undergo quality acceptance after completion. Quality acceptance supports various acceptance methods, including unit project assessment, sub-project assessment, sub-project assessment, unit project acceptance, contract project acceptance, project phase acceptance, and major project acceptance. Quality acceptance can be organized by the owner, the supervision unit, or the construction unit for self-inspection. Each unit can be responsible for data maintenance by the quality management personnel of the organization unit according to the different organizational units, and enter the data into the system through the D8524 screen. Including: (1) Enter the D8524 quality assessment and acceptance screen and enter the PAGE1 quality acceptance information; (2) In the D8524 quality assessment and acceptance screen, enter the PAGE2 quality acceptance result information; (3) Save and exit.

[0130] In addition, the working principles of the software and hardware involved in the above technical solutions are as follows:

[0131] 1. D8502 unit engineering decomposition function:

[0132] The main function of this screen is to log in and maintain the engineering decomposition codes related to the engineering contract in the quality management process (including the entry, query, modification and deletion of engineering decomposition codes). During the entry process, the user only needs to enter the relevant contract code (can be selected and entered through LOV) and enter the engineering decomposition code of the contract according to the engineering decomposition code rules (can query the existing engineering decomposition code through LOV). After this module confirms that the engineering decomposition code entered this time is valid, it will automatically decompose it into unit engineering number, sub-project number, sub-item engineering number and unit engineering number and display them on the screen. At the same time, it will automatically identify the code to determine its level and display it on the screen. This greatly reduces the amount of code entry for users.

[0133] During the query process, users can query by contract code, contract code + project breakdown code or contract code + unit project number, etc. If you want to query the specific quality of the part corresponding to the project breakdown code, you can navigate to other modules of the quality management system using the navigation keys below.

[0134] Interface field description:

[0135] Contract code - The contract code can be entered manually but must exist in the data on screen D4001 and its contract status must be '3'. It can also be entered and queried using the value list LOV or code input CodeInput.

[0136] Contract Name - This field is the display item of the contract code description, which is automatically entered by the system. If the description you see is incomplete, you can click it with the mouse, and then move the cursor to see the complete description of the contract code.

[0137] Project code - that is, the project decomposition code corresponding to the contract entered previously. The maximum length of this code is 9 characters long. It can also be entered as 1, 3, 5, or 9 digits, which are unit project code, sub-project code, sub-item project code, and unit project code. When other digits are entered, the system reports an error and provides the correct entry format. When in the entry state, the first project code entered must be a new code for the contract.

[0305] In summary, the method and system for quantifying the quality of construction projects provided by this embodiment provide a set of powerful modern management means for inputting, querying, and tabulating quality control tracking information from raw materials, semi-finished products to finished products in each link of construction quality. The system also provides an extremely practical module - tracking the actual progress of the project and the actual main indicator of the project quantity. Quality tracking and quality evaluation require a comparison standard. These inspection indicators and inspection standards need to be established once before the implementation of actual quality tracking or in stages and batches according to the progress of the project. The operation of the quality management subsystem can be divided into three parts, namely, the establishment of quality standards (including material or test piece standards and process inspection standards), the collection of actual quality tracking information, and the output of quality reports. It is mainly used to ensure and implement construction quality management. The implementation of construction quality management mainly involves the following aspects: test and inspection of construction quality, including: engineering materials, semi-finished products, finished products, concrete material grading ratio and mix ratio test before concrete pouring, sampling inspection of engineering materials in any construction project or part, etc. Quality control and management in construction preparation, including the formulation and management of construction specifications, standards and coding, as well as partial process tests and process inspections before construction. Quality control and management during the construction process, including: construction material certification management, construction process inspection and assurance, construction quality inspection certification and project acceptance, and project quality accident management.
