🧮 𝗢𝗽𝗲𝗻𝗖𝗼𝗻𝘀𝘁𝗿𝘂𝗰𝘁𝗶𝗼𝗻𝗘𝘀𝘁𝗶𝗺𝗮𝘁𝗲 - 𝗼𝗽𝗲𝗻-𝘀𝗼𝘂𝗿𝗰𝗲 𝗰𝗼𝗻𝘀𝘁𝗿𝘂𝗰𝘁𝗶𝗼𝗻 𝘄𝗼𝗿𝗸𝘀 𝗱𝗮𝘁𝗮𝗯𝗮𝘀𝗲: 55,719 construction “recipes” - a codified language of how we build

Not so long ago, cooking recipes lived only in family books. Today any dish is two clicks away. Construction is moving in the same direction: installing a drywall partition in Brazil is, in essence, the same process as in Germany – same physics, labor steps and resource use. The only difference is the local cost of people, materials and machines.

For almost 10 years I’ve been automating cost calculations and connecting CAD (BIM) with ERP systems. The workflows are ready (n8n, Sim_ai, Jupyter Notebook etc.) – but I always lacked one thing: a clean, detailed and open database of works described through resources.

This is why I built this open-source database in 9 languages for 9 countries.

𝐖𝐡𝐚𝐭’𝐬 𝐢𝐧𝐬𝐢𝐝𝐞:
55,719 unique work items based on 27,672 resources, each with:
▪️ labor hours
▪️ machine hours
▪️ water consumption
▪️ electricity consumption
▪️ CO₂ footprint

𝗪𝗵𝘆 𝗶𝘁 𝗺𝗮𝘁𝘁𝗲𝗿𝘀:
✅ 𝟰𝗗/𝟱𝗗/𝟲𝗗 𝗕𝗜𝗠: connect BIM quantities with real work “recipes”.
✅ 𝗧𝗿𝗮𝗻𝘀𝗽𝗮𝗿𝗲𝗻𝗰𝘆: shared language between client and contractor; fair norms and volumes behind every invoice.
✅ 𝗔𝗻𝗮𝗹𝘆𝘁𝗶𝗰𝘀 & 𝗠𝗟: data is ready for vectorisation and ML/LLM use.
I’ve already vectorised the dataset so we can tap into decades of structured know-how collected from real construction sites.

🌍 𝗟𝗮𝗻𝗴𝘂𝗮𝗴𝗲𝘀 & 𝗽𝗿𝗶𝗰𝗲 𝗹𝗲𝘃𝗲𝗹𝘀
The database and regional price levels are available in:
🇩🇪 Deutsch – Berlin
🇨🇦 English – Toronto
🇫🇷 Français – Paris
🇪🇸 Español – Barcelona
🇮🇳 हिन्दी – Mumbai
🇧🇷 Português – São Paulo
🇷🇺 Русский – St. Petersburg
🇨🇳 中文 – Shanghai
🇦🇪 العربية – Dubai
City = reference price level (you can change it later).

Once the release is ready, I’ll contact you with early access to the tables and implementation guide.

Open CAD (BIM) Data + Open Resource Databases = transparent processes, fair budgets and a new culture of trust in construction 🤝
