StakeholderWhat They Get
🏢 **Client / Investor**Full cost transparency, resource breakdown, price justification for investment decisions
📊 **Cost Estimator**Detailed rates, labor hours, material quantities, equipment costs — ready for BOQ generation
👷 **Site Manager / Foreman**Work composition, resource requirements, labor norms for daily planning and execution
🔧 **Contractor / Executor**Complete specifications, unit rates, productivity benchmarks for accurate bidding and scheduling

Export to Excel, PDF, HTML, ERP systems, BIM platforms — the structured 85-field schema ensures data integrity across all outputs.

About

DDC CWICR (Construction Work Items, Components & Resources) is an open database for construction cost estimation, covering the full spectrum of construction activities - from earthworks and concrete placement to specialized installation work.

The database draws on sources describing modern construction practices across Eurasia and the Asia-Pacific region, where a unified technical standardization ecosystem serves as a common engineering language for more than ten dynamically developing economies. DDC CWICR represents an effort to harmonize open standards by establishing a single regulatory framework for capital project management in multiple languages.

<p align="center"> <br> <img src="https://github.com/datadrivenconstruction/cad2data-Revit-IFC-DWG-DGN-pipeline-with-conversion-validation-qto/blob/main/DDC_in_additon/DDC_readme_content/DDC%20CWICR%20GEOGRAPHIC%20COVERAGE.jpg" width="100%"/> <br></br> </p>

The structured data can be accessed through tabular formats (XLSX, CSV, Parquet) or queried conversationally via LLM, enabling specialists to integrate construction work descriptions (QDRANT vector database) into automated pipelines and workflows using plain language or concise queries.

🚀 Getting Started

⚠️ n8n 2.0+ Setup Required

Starting from n8n version 2.0, the Execute Command node is disabled by default for security reasons. Without the configuration below, workflows using Execute Command (especially CAD/BIM Pipeline) will not work — nodes will show with a question mark or won't be recognized.

Verify Setup

  1. Start n8n
  2. Click + → search for "Execute Command"
  3. If the node appears → ✅ you're all set!

📌 简介

DDC CWICR 是一个集成了建筑工程工项、组件与资源的专业化平台。通过结合 n8n 工作流自动化技术,该项目能够基于文本描述、现场照片以及 CAD/BIM 模型数据,实现自动化的工程量估算与成本计算,为建筑行业提供结构化的数据支持。

⚡ 功能介绍

项目具备强大的 AI 驱动能力,例如通过 AI Photo → Estimate 功能,用户只需拍摄现场照片,即可利用 GPT-4 Vision 自动构建工程量清单(BoQ)。此外,系统还支持将复杂的建筑描述转化为标准化的结构化数据,适用于多种业务场景。

📋 环境依赖

在使用本项目前,请确保已安装 n8n v1.0 或更高版本(建议使用 v2.0+)。由于项目涉及复杂的 CAD/BIM 数据处理,环境需支持相应的 Python 运行环境及相关依赖库,以确保工作流能够正常执行。

🛠 安装步骤(Docker/pip/源码)

项目提供了多种部署与快速上手方式:包括基于 Python 的表格数据与语义搜索快速启动、针对开发者提供的 Python、JavaScript、Rust 等多语言示例,以及通过 n8n 进行集成。特别注意:在 n8n 2.0+ 环境下,需确保已启用 Execute Command 节点以支持 CAD/BIM Pipeline。

🚀 使用教程

本项目支持从入门级到高级别的多种应用场景。入门用户可以进行成本基准对比(Price Benchmarking)和标书估算;中级用户可利用 ETL/BI Pipelines 进行本地化处理或 CO₂ 计算;高级用户则可将其应用于 AI/ML 模型训练、CAD (BIM) 5D 模型及深度投资审计。

⚙️ 配置说明(含 MCP / env)

在配置阶段,用户需要在 n8n 的 TOKEN 节点中正确设置各类 API 密钥。关键参数包括 Telegram Bot Token、OpenAI API Key、Gemini API Key 以及 Qdrant 向量数据库的 URL 和 API Key,以确保 AI 模块与数据库连接正常。

🔌 API 说明

项目提供了一个免费的 REST API —— Pricing Search API,专门用于建筑价格查询。开发者可以通过标准的 API Endpoints 进行搜索、语言转换及统计数据获取,并支持使用 cURL、Python 和 JavaScript 进行快速集成开发。

🔄 工作流/模块

本项目通过 n8n 实现高度自动化的工作流。用户可以根据输入类型选择不同的 Workflow,甚至可以通过 Telegram 端的 Live Demo Bots 进行即时测试。工作流涵盖了从文本估算机器人(Text Estimator Bot)到照片成本估算机器人(Photo Cost Estimator)的完整链路。

❓ FAQ 摘要

针对常见问题,如在 n8n 2.0+ 版本中找不到 Execute Command 节点,需通过设置环境变量 `NODES_EXCLUDE=[]` 来解决;若遇到“未找到 Excel 文件”的错误,请检查 `path_to_convert` 路径配置是否正确。

🎯 aiskill88 AI 点评 A 级 2026-05-23
