Workflow Orchestration for Infrastructure Construction Marketing Content

Data for infrastructure construction marketing content comes from public bidding announcements, construction logs, enterprise qualification filing

What data looks like for this category

Data for infrastructure construction marketing content comes from public bidding announcements, construction logs, enterprise qualification filing documents, regional infrastructure planning plans, and past project case documents. Data updates trigger based on project progress. New data files are generated during bidding, construction start, and completion stages. Each document typically includes structured fields such as section number, project cost, construction period, and technical parameters. Some bidding documents include CAD drawing attachments. Document length varies widely, from thousands of words of project descriptions to dozens of pages of complete construction plans.

What constraints these characteristics impose on workflow orchestration

The multi-source nature and irregular update schedule of infrastructure construction data require workflows to support on-demand triggering mechanisms, adapting to sudden updates such as project bidding and construction start. Documents include CAD drawing attachments and long text content, so workflows need built-in non-text format parsing nodes and support for long document segmentation configuration to avoid parsing timeouts. The diversity of structured fields requires workflows to configure field mapping rules, directly connecting exclusive fields such as project cost and construction period to the marketing content generation link. Large differences in document structures across different projects require workflows to retain adjustable parsing templates to adapt to the document format requirements of different sections.

How to set configurations

Configuration ItemRecommended ValueRationale
PARSE_FILE_SUPPORTED_FORMATS["pdf", "docx", "xlsx", "dwg", "zip"]Common document formats for infrastructure construction include CAD drawings (dwg), engineering lists (xlsx), proposal documents (docx), etc., covering core data source types
UPLOAD_FILE_MAX_SIZE2000 MBCAD drawing packages and complete construction proposal packages for infrastructure projects are usually large in size, requiring adaptation to single-file upload limits
WORKFLOW_TRIGGER_MODEmanual + webhookMarketing content generation needs to be triggered on demand according to project progress. Webhook adapts to API call scenarios, while manual adapts to temporary editing needs
MAX_DOCUMENT_SEGMENT_LENGTH1000–1200 charactersInfrastructure construction documents contain a large number of professional terms and long paragraphs. The segmentation length adapts to the context window requirements of subsequent content generation
FIELD_EXTRACTION_RULESCalibrated based on actual testingField naming in documents of different infrastructure projects varies, so extraction rules need to be adjusted for specific data sources
WORKFLOW_TIMEOUT_SECONDS600 secondsLong document parsing and multi-node orchestration take a long time to execute, so sufficient execution time must be reserved

The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing settings.

Three Common Mistakes

  • A 413 Request Entity Too Large error is returned when calling the workflow API. The cause is failure to adjust the UPLOAD_FILE_MAX_SIZE configuration to adapt to the upload requirements of large-volume infrastructure project documents.
  • Marketing content returned after workflow execution lacks exclusive fields such as project cost and construction period. The cause is failure to configure FIELD_EXTRACTION_RULES and correctly extract structured fields from infrastructure documents.
  • The workflow prompts that the knowledge base does not exist after passing in the global variable knowledge base ID. The cause is failure to pass the knowledge base ID via webhook parameters, with incorrect reliance on inactive global variable configurations.

How to Verify Proper Configuration

  • Upload a typical infrastructure construction document that includes CAD attachments and structured fields, check whether the parsing node can correctly extract fields such as section number and project cost, and verify whether the FIELD_EXTRACTION_RULES configuration takes effect.
  • Call the workflow API to upload a large-volume engineering document package, check whether execution can be triggered normally and parsing completed, and verify whether the UPLOAD_FILE_MAX_SIZE configuration is adapted.
  • Trigger the workflow via webhook, check whether the marketing content generation node can connect to the extracted structured fields, and verify whether the WORKFLOW_TRIGGER_MODE configuration is correct.
  • View the workflow execution log to confirm that the execution duration does not exceed the preset threshold, and verify whether the WORKFLOW_TIMEOUT_SECONDS configuration is reasonable.
