Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to an integrated method for design planning, budget-limited design and procurement based on data building blocks. Background Technology

[0002] In the field of architectural engineering technology, information barriers between design, cost, procurement, and construction have long existed, leading to problems such as frequent design changes, uncontrolled costs, and a disconnect between design, procurement, and construction. Therefore, there is a need for an integrated approach to design planning, budget-constrained design, and procurement based on data building blocks. This approach can address the technical problems of frequent design changes, uncontrolled costs, and a disconnect between design, procurement, and construction caused by information barriers between these four areas in existing technologies. Summary of the Invention

[0003] The purpose of this invention is to provide an integrated design planning, budget-limited design, and procurement method based on data building blocks, which can solve the technical problems in the prior art caused by information barriers between design, cost, procurement, and construction, resulting in frequent changes in design schemes, uncontrolled costs, and disconnect between design, procurement, and construction.

[0004] This invention is implemented as follows:

[0005] An integrated approach to design planning, budget-constrained design, and procurement based on data building blocks includes the following steps:

[0006] Step 1: Designers input the design parameters into a structured tree model based on data building blocks;

[0007] Step 2: Based on the design parameters input in Step 1, generate several technical solutions using the data building block library and supply chain database;

[0008] Step 3: Compare and select from several technical solutions, and decide on the final technical solution;

[0009] Step 4: Generate technical documents based on the final technical solution;

[0010] Step 5: Execute the procurement based on the generated technical documents and generate an order;

[0011] Step 6: Data maintenance.

[0012] Step 1 includes the following sub-steps:

[0013] Step 11: Designers input design parameters into the tree model based on data blocks, or select the corresponding design parameters in the tree model;

[0014] Step 12: Analyze the design parameters based on the tree model, and call the matching data blocks from the data block library using AI algorithms;

[0015] Step 13: Link data building blocks to the enterprise standard material coding library;

[0016] Step 14: Dynamically connect the supply chain database based on the material codes associated with data building blocks.

[0017] In step 11, the design parameters include building type, business format, grade, specifications, technology, seismic resistance level, green building star rating, and specific design requirements for each functional area.

[0018] In step 12, the matching criteria for design parameters and data blocks include: design feature parameters, grade requirements, project location, and calculation period range.

[0019] In step 13, each data block is associated with a material code in the enterprise's standard material code library. The material code includes the material category, specifications, brand, and supplier.

[0020] In step 14, the supply chain database contains material codes that match the enterprise's standard material code library. The supply chain database is queried in real time based on the material codes associated with data blocks to obtain supply chain data, which is used to support procurement feasibility analysis.

[0021] Supply chain data includes supplier lists, historical purchase prices, inventory status, delivery cycles, and performance evaluations.

[0022] In step 2, the design parameters are evaluated based on the data building block library and supply chain database. The evaluation dimensions include: cost, schedule, quality, procurement feasibility, and construction convenience.

[0023] Costs include material prices, construction costs, and comprehensive unit prices; construction period includes supply cycle and construction cycle; quality includes material performance and brand reputation; procurement feasibility includes supplier resources and geographical coverage; and construction convenience includes process maturity and adaptability to site conditions.

[0024] In step 3, a weighted model for comparing technical solutions is defined, and the comprehensive score of several technical solutions is calculated using the weighted model. The weighted parameters of the weighted model include cost, quality, construction period, and procurement feasibility.

[0025] At the same time, technical personnel from relevant departments such as design, business, procurement, technology, and engineering collaborate on the review, support human intervention, and support fine-tuning of the technical solution, so as to ultimately confirm the optimal technical solution.

[0026] In step 4, the technical documents include four core documents: "Limited Design Task Book", "Detailed Node Construction Drawings", "Technical Specifications", and "Procurement Requirements List".

[0027] Among them, the "Limited Cost Design Task Book" clearly defines the target cost ceiling and the matching design / feature parameters, construction methods, material grade requirements, etc.; the "Detailed Node Construction Atlas" outputs standardized CAD / BIM construction details; the "Technical Specifications" contains complete technical parameters; and the "Procurement Requirements List" matches the material codes and can be directly imported into the procurement system to support order placement.

[0028] In step 6, the actual data during the project execution process is updated to the data block library and synchronized with the data blocks. The price, supplier, and process parameters in the data blocks are updated to continuously optimize the data blocks.

[0029] Meanwhile, during project execution, data on actual purchase prices and supplier performance are written back to the supply chain database, and data on construction feedback is written back to the enterprise database.

[0030] Compared with the prior art, the present invention has the following advantages:

[0031] This invention uses "data building blocks" as information hubs and deeply integrates two major technologies: tree-structured models and dynamic data integration using AI algorithms. It achieves intelligent connectivity across the entire chain from design parameters to procurement orders, enabling rational decision-making at the design end, precise cost control at the cost end, efficient execution at the procurement end, and standardized implementation at the construction end. This forms a digital closed loop covering the entire lifecycle of "design-procurement-construction-operation and maintenance," which is conducive to promoting the continuous development of the construction industry towards intelligent construction and lean management. It is not only applicable to civil engineering, mechanical and electrical engineering, and decoration, but can also be extended to diverse business formats such as landscaping, intelligent systems, and medical specialties, demonstrating strong scalability and industry universality. Detailed Implementation

[0032] The present invention will be further described below with reference to specific embodiments.

[0033] A data-block-based integrated approach for design planning, budget-constrained design, and procurement includes the following steps:

[0034] Step 1: Designers input the design parameters into a structured tree model based on data building blocks.

[0035] In step 1, the architecture and construction process of the tree model based on data building blocks are as follows:

[0036] Create underlying infrastructure data applicable to various business projects, namely J4 component-level building blocks, and dynamically capture enterprise cost prices from enterprise databases (such as enterprise's own subcontracting and cost databases) and provincial and municipal quota prices from external databases through AI algorithms.

[0037] J4 part-level building blocks contain: Specialty (used to generate the specialty label to which the J4 part-level building block belongs), System (used to generate the system label to which the J4 part-level building block belongs), Component (used to generate the component label to which the J4 part-level building block belongs), Part (used to determine the part name corresponding to the J4 part-level building block), Grade (i.e., part grade, which can be divided into Grade A, Grade B, Grade C, etc.), Part Unit (e.g., unit, etc.), Main design feature parameters filled in by the designer (which may include duct type, 1390m³ / h, cooling 10.0kW, heating 11.2kW, quota, static pressure 0-30Pa, etc., based on which the cost and quota price in the enterprise database are matched), and Bill of Quantities (including bill of quantities code, bill of quantities name, unit of measurement, content, etc., the corresponding list of parts). The system includes: single code (based on which the quota price is matched), main material consumption (which may include main material content, main material loss rate, etc.), main material information (which may include main material content, long description of supply chain materials - matching characters, long description of supply chain materials - avoiding characters, supply chain materials - filtering, supply chain materials - price range, etc., which are connected to the enterprise database and the enterprise cost price is captured according to the linking rules to make it match the feature parameters), regional prices (e.g., main material cost price, construction cost price, comprehensive cost price, quota price, quota number, profit margin, etc. in South China (Guangzhou City), which can automatically capture matching data from the enterprise database through main material cost price, construction cost price, comprehensive cost price, quota price, etc., and store the price after statistical analysis. The parts correspond to the quota number, which can be used to match the quota price).

[0038] By using the data information of J4 component-level building blocks, AI algorithms are used to automatically and dynamically capture data from external databases such as enterprise databases, labor, material, and machinery cost prices, provincial and municipal quotas, information prices, and market prices to calculate component quota prices. This achieves the coupling of design parameters, technical specifications, grades, and cost data of J4 component-level building blocks, ensuring that the prices used in project cost calculations are the corresponding prices within the project location and calculation period.

[0039] The configured AI algorithms can include existing rule engines, natural language processing (NLP), similarity calculation, machine learning classification, random forests, etc., and the appropriate AI algorithm can be selected based on the information contained in the J4 part-level building blocks.

[0040] The underlying infrastructure data J4 component-level blocks are combined with preset business projects, making them easy to replace and add, and easy to operate.

[0041] Based on the J4 part-level building blocks, J3 component-level building blocks, J2 system-level building blocks, and J1 professional-level building blocks are created by combining them level by level and stored in the data building block library. The J4 part-level building blocks, J3 component-level building blocks, J2 system-level building blocks, and J1 professional-level building blocks are the data building blocks.

[0042] J3 component-level building blocks are datasets composed of multiple J4 part-level building blocks grouped according to design logic relationships. The price of a J3 component-level building block is composed of the quantity and price of each J4 part-level building block. J2 system-level building blocks are datasets composed of multiple J3 component-level building blocks grouped according to design logic relationships. The price of a J2 system-level building block is composed of the quantity and price of each J3 component-level building block. J1 professional-level building blocks are datasets composed of multiple J2 system-level building blocks grouped according to design logic relationships. J1 professional-level building blocks, J2 system-level building blocks, and J3 component-level building blocks are all characterized by flexibility and scalability.

[0043] Create independent calculation modules commonly used in various business projects, and call matching J1 professional-grade building blocks for each calculation module to form a tree model.

[0044] The measurement module includes M1 project-level module, M2 sub-item-level module, M3 functional area-level module, M4 subdivided area-level module, M5 subdivided sub-area-level module, and M6 room-level module.

[0045] Each of the aforementioned calculation modules is an independent dataset, containing input information tables, output information tables, content indicator centers, and associated J1 professional-grade building blocks. Depending on the actual engineering project, the associated J1 professional-grade building blocks for each calculation module may include one or more of the following: outdoor engineering, interior decoration engineering, building engineering, structural engineering, installation engineering, curtain wall engineering, exterior door and window engineering, elevator engineering, floodlighting, indoor signage engineering, logistics system engineering, medical gas engineering, radiation shielding engineering, cleanroom engineering, laboratory engineering, kitchen engineering, gas engineering, and laundry engineering; other types of engineering projects may also be included.

[0046] In the tree model described above, the M2 sub-item level module represents a single building in a specific engineering project, mainly determined by the project's business type and scale, and may include above-ground buildings and basements; the M3 functional area level module represents areas within a specific M2 sub-item level module, divided according to the building's function, mainly determined by the floor division of a single building, and may include above-ground floor functional areas, underground non-civil defense parking garages, and civil defense areas; the M4 sub-area level module represents areas further subdivided within a specific M3 functional area level module based on its floor function distribution, and may include main use spaces, public spaces, equipment rooms, non-motorized vehicle garages, motorized vehicle garages, personnel shelters, material warehouses, and central hospitals, etc.; the M5 sub-sub-area level module represents areas further subdivided within a specific M4 sub-area level module based on subdivided functions; and the M6 ​​room level module represents various types of rooms within a specific M5 sub-sub-area level module.

[0047] Assign unique ID codes to J4 part-level blocks, J3 component-level blocks, J2 system-level blocks, J1 professional-level blocks, and each calculation module, and import them into the data block library.

[0048] Step 1 includes the following sub-steps:

[0049] Step 11: Designers input design parameters into the tree model based on data blocks, or select the corresponding design parameters in the tree model.

[0050] The design parameters include building type, business format, grade, specifications, process, seismic resistance level, green building star rating, and specific design requirements for each functional area (corresponding to M3 functional area level module, M4 sub-area level module, M5 sub-sub-area level module and M6 room level module).

[0051] Step 12: Analyze the design parameters based on the tree model (calculation modules M1~M6), and call the matching data blocks (J1~J4 level blocks) from the data block library through AI algorithm.

[0052] In step 12, the matching criteria for design parameters and data blocks include, but are not limited to: design feature parameters, grade requirements, project location, and calculation period (time validity), to ensure strong coupling between design intent and cost, process, and supply chain information.

[0053] Step 13: Link data building blocks to the enterprise standard material coding library.

[0054] Specifically, each data block is associated with a material code in the enterprise's standard material code library. The material code includes information such as material classification, specifications, brand, and supplier, achieving one code for each item and one code for the entire supply chain.

[0055] The enterprise standard material code library is one of the commonly used databases in enterprise databases. It is used to uniquely encode materials, which facilitates the retrieval of materials and their codes. It is a conventional technical means in this field to associate data blocks with codes in the enterprise standard material code library based on material information, and will not be elaborated here.

[0056] Step 14: Dynamically connect the supply chain database based on the material codes associated with data building blocks.

[0057] The supply chain database contains material codes that match the enterprise's standard material code library. Based on the material codes associated with data blocks, the supply chain database can be queried in real time to obtain supply chain data, which is used to support procurement feasibility analysis.

[0058] The aforementioned supply chain data includes supplier directories, historical purchase prices, inventory status, delivery cycles, and performance evaluations. The supply chain database can consist of relevant data from the enterprise's internal material procurement supply chain. The data types in the supply chain database can be configured according to actual procurement needs, making it one of the conventional enterprise databases in this field, and will not be elaborated further here.

[0059] Step 2: Based on the design parameters input in Step 1, generate several technical solutions using the data building block library and supply chain database.

[0060] Preferably, 2 to 3 technical solutions can be generated for selection.

[0061] In step 2, the design parameters are evaluated based on the data building block library and supply chain database. The evaluation dimensions include: cost, schedule, quality, procurement feasibility, and construction convenience.

[0062] Costs include material prices, construction costs, and comprehensive unit prices; construction period includes supply cycle and construction cycle (which depends on the complexity of construction); quality includes material performance and brand reputation; procurement feasibility includes supplier resources and geographical coverage; and construction convenience includes process maturity and adaptability to site conditions.

[0063] Step 3: Compare and select several technical solutions, and decide on the final technical solution.

[0064] Step 3 includes the following sub-steps:

[0065] Specifically, a weighted model for comparing custom technical solutions is used to calculate the comprehensive score of several technical solutions.

[0066] The weighting parameters of the weighted model include cost, quality, schedule, and procurement feasibility.

[0067] For example, the weighting coefficient for cost is 40%, the weighting coefficient for quality is 30%, the weighting coefficient for construction period is 20%, and the weighting coefficient for procurement is 10%. The weighting parameters and their weighting coefficients can be adjusted adaptively according to actual needs, and the comprehensive score of each technical solution can be automatically calculated based on the weighting model.

[0068] Preferably, multiple technical solutions can be generated and quantitatively scored based on AI technologies such as rule engines, NLP (Neuro-Linguistic Programming), similarity calculation, and random forest classification, taking into account dimensions such as cost, construction period, quality, procurement feasibility, and construction convenience.

[0069] The weighted model is a commonly used method for evaluating solutions in this field, and will not be elaborated on here.

[0070] Meanwhile, technical personnel from relevant departments such as design, business, procurement, technology, and engineering can collaborate on the review, support manual intervention, and facilitate fine-tuning of the technical solution to ultimately confirm the optimal technical solution.

[0071] Step 4: Generate technical documents based on the final technical solution.

[0072] The technical documents include four core documents: "Design Task Book with Budget Limits", "Detailed Node Construction Drawings", "Technical Specifications", and "Procurement Requirements List". Among them, the "Design Task Book with Budget Limits" clearly defines the target cost ceiling and the matching design / feature parameters, construction methods, material grade requirements, etc.; the "Detailed Node Construction Drawings" outputs standardized CAD / BIM construction details; the "Technical Specifications" contains complete technical parameters; and the "Procurement Requirements List" matches material codes and can be directly imported into the procurement system to support order placement.

[0073] Step 5: Execute the procurement based on the generated technical documents and generate an order.

[0074] Step 6: Data maintenance.

[0075] The actual data during project execution (such as purchase price, supplier performance, delivery cycle, new technologies and processes) is updated to the data block library. Synchronized with the data blocks, the prices, suppliers, and process parameters in the data blocks are updated to continuously optimize the accuracy and usability of the data blocks, thereby achieving continuous accumulation of knowledge assets and self-optimization of the tree model.

[0076] Meanwhile, during project execution, data such as actual purchase price and supplier performance are written back to the supply chain database, and data such as construction feedback are written back to the enterprise database.

[0077] In construction projects, the technical effects of implementing this invention include:

[0078] 1. Improve decision-making quality: Comprehensive multi-dimensional decisions on technology, economics, procurement, and construction can be made during the design phase.

[0079] 2. Improve work efficiency: The generation time of the Technical Specifications can be shortened from days to 5 minutes, the generation time of the Procurement Requirements List can be shortened from days to real-time generation, and the cost assessment of design changes can be shortened from days to seconds.

[0080] 3. Cost control in advance: The budget design indicators are determined in the planning stage, which can effectively avoid exceeding the budget later.

[0081] 4. Precise Procurement Matching: Orders are generated directly through material codes, realizing "design as procurement".

[0082] 5. Knowledge Asset Accumulation: The technical specifications of building materials and detailed construction methods for each project are accumulated into standardized data blocks, supporting the continuous enrichment of the enterprise's knowledge base.
