What the data for this category looks like
Construction engineering financial report data primarily comes from project construction ledgers, monthly progress payment applications, quarterly cost accounting forms, annual settlement audit reports, and cost consulting documents. Data update rhythm varies by project phase: monthly updates of progress and costs during construction, final reports submitted at settlement after completion, and supplementary updates within 1 to 2 years post-completion for retouched projects. Single documents include structures such as project overview, labor cost breakdown, material consumption list, machinery usage fees, measure items, and audit adjustment items. Fields include quantified items with clear units: building area (㎡), unit cost (yuan/㎡), steel consumption (tons), concrete placement volume (cubic meters). Temporary measure fee fields are added for some custom projects.
Constraints on Deployment and Upgrade
The multi-dimensional detailed structure, large single-file size, and phased update characteristics of construction engineering financial reports impose multiple constraints on deployment and upgrade. First, large, long documents require adjustments to upload and parsing timeout and capacity configurations to prevent task interruptions. Second, custom fields and multi-category label requirements demand that the knowledge base supports dynamic field mapping and collection label functions. Third, the phased update characteristic requires compatibility with both incremental synchronization and full rebuild data update modes during upgrades, to avoid overwriting historical project data. Fourth, parsing multi-unit quantitative fields requires enabling strict format validation configurations to ensure accurate data extraction.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 2000 MB | Annual construction engineering financial report PDFs often include multi-project settlement and audit reports, with individual file sizes exceeding 1.5 GB |
PARSE_FILE_TIMEOUT_SECONDS | 1200 seconds | Long document parsing requires traversing multi-page details, so the timeout threshold must cover the full parsing process |
maxContext | 8000–12000 characters | Financial reports include multi-dimensional details such as labor, materials, and machinery, requiring sufficient context to retain associated fields |
Recall Count | Top 8–12 entries | Must cover cost data for different sub-projects, avoiding missed key details |
Similarity Threshold | 0.75–0.85 | Distinguishes cost structures of different projects in the same category, avoiding recall of non-target project data |
MINIO_UPLOAD_CHUNK_SIZE | 50 MB | Adapts to private deployment network environments, resolving file upload lag issues |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Issue: After upgrading to the latest open-source version, the knowledge base collection label function cannot be enabled, with error prompt
label_feature_not_supported. Cause: TheENABLE_KNOWLEDGE_LABELparameter was not enabled in the deployment configuration. Construction engineering projects require classified labeling of data by project, so this function is a necessary configuration. - Issue: Private deployment knowledge base cannot add image datasets, with no corresponding entry in the interface. Cause: Image parsing and storage mounting were not enabled in the deployment configuration. Construction financial reports often include construction drawings and material delivery photos, so this configuration must be enabled.
- Issue: Parsing fails for an identical CSV-format financial report file after upgrade, with error prompt
field_mismatch. Cause: TheCSV_STRICT_PARSEparameter is enabled by default after upgrade. Construction financial reports include custom supplementary fields such as temporary measure items, so the parsing mode must be adjusted to relaxed mode.
How to Verify Successful Configuration
- Upload a 1.5 GB construction financial report PDF, wait for parsing to complete, and confirm the task status is
successto verify upload and parsing configurations are active. - Initiate a query for a specific project’s cost data, verify that the recall results include at least 8 detail entries, and that the match rate of results aligns with the preset threshold.
- Check the MinIO storage directory, confirm that uploaded financial report files have completed chunked uploads with no interruptions, to verify chunked upload configurations adapt to the network environment.
- Attempt to add custom field labels to the knowledge base collection, confirm the label function operates normally, to verify label configuration parameters are active.
