Talk about support

With the help of Python and especially the pandas library, as the DataDrivenConstruction team does, we are now able to perform delivery checks four times faster. By turning IFC data into a pandas DataFrame and comparing it with quantification tables or classification databases, we have made our expertise fast and reliable.

AI in construction

AI that works on your data.

AI is only as good as the data it can reach. We first make your models, PDFs and cost data readable, then put agents to work on them, with clear limits and a person who signs off.

  • AI agents on CAD/BIM data

    Claude Code, Cursor or Copilot run takeoffs, model checks and reports from one sentence, using our converters and skills.

    Takeoff for level 3, flag walls without fire rating

  • LLM + RAG over project documents

    Ask questions across specifications, contracts and minutes. Answers cite the page they came from.

    Which penalties apply if the facade is late?

  • AI cost estimation

    Match BOQ positions and model elements to 55,700 work items in 30 regions, with a human signing off.

    Price this BOQ against the regional database

  • Classification & data quality

    Classify elements to DIN 276, Uniformat or your own codes and validate models against requirement sheets automatically.

    Map every element to DIN 276 and list the gaps

  • Integrations, MCP & open interfaces

    Connect ERP, CAD, PDF and scheduling tools so AI can reach your systems through clean, documented interfaces.

Engineers on our open n8n workflow, on LinkedIn

  • Impressive work. This is exactly the kind of automation that removes repetitive effort and lets experienced people focus on judgment and risk instead of data cleanup. Fast, consistent feedback on cost and time earlier in the process is where teams really win. Open workflows like this push the industry in the right direction.

    Steven MyersBlueLine VDC, llc
  • Automating project cost estimation with AI presents exciting new opportunities. This workflow's potential to streamline processes and enhance efficiency is noteworthy.

    Anuj Kumar GuptaCOO, Co-Founder at Vavetek.AI
  • This is an excellent demonstration of how automation can truly transform project workflows, freeing up valuable time for deeper analysis. We appreciate the focus on empowering traditional roles with advanced capabilities, rather than replacing them entirely. This approach fosters growth and skill development within the industry.

DataDrivenConstruction workshop at Lindner Group

Lindner Group

In-house workshop

Structured construction data to keep the overview, spot supplements early and connect planning with execution.

  • Structured data
  • Planning ↔ execution

What happens when you not only organize construction processes, but also analyse them intelligently? This was the topic of our workshop with Artem Boiko on “Data-Driven Construction”. The focus was on the question of how we can make better use of existing data - to make construction projects more efficient, more transparent and less error-prone. Using specific application examples, Artem showed how structured construction data can help to maintain an overview, identify supplements at an early stage and improve communication between planning and execution. Particularly exciting: how digital tools and models can already be used today to automate processes. Data-driven construction is no longer a topic for the future - we are right in the middle of it. The workshop showed how great the potential is if we work together and really make data work for us.

DataDrivenConstruction workshop at Herbert Gruppe

Herbert Gruppe

2-day training · n8n + Python

Hands-on training for building-services specialists: CAD/BIM data workflows with n8n and Python, from the first script to a running pipeline.

  • Python
  • n8n pipelines

I found the DataDrivenConstruction training overall really exciting and very enriching. What I particularly liked: the “historical” background on the various CAD softwares (that was fascinating to hear and felt like investigative journalism); the interesting approach to automation via DataFrames; your own hands-on examples of process automation in construction; and the look at current trends like Claude Code and OpenClaw - you really brought the topic to life. The only downside: it was really a lot of input in just two days. At the same time, you showed us very well how we can continue to orient ourselves - for example by structured recording of our processes on the Miro board. Thanks again for the training and the exchange.

Philip BeckerTeam Lead Prefabrication · Herbert Gruppe

I found the DataDrivenConstruction workshop really interesting. In my opinion, everyone could follow along. You can tell from your slides how much time, perseverance and effort you put into it. The live presentations were great too. The only thing I’d criticise is the number of slides - there were just too many. But that’s complaining at the highest level. Overall, it was the best workshop I’ve ever attended. And on top of that, you’re a really pleasant person.

Kai SchmittSoftware Engineer for BIM Automation · Dimexcon (Herbert Gruppe)

Artem Boiko delivered an impressive presentation at our BIM Cluster BW Day 2024 on the use of data in relation to BIM. His expertise in presenting a new vision for the application of data was truly inspiring. With his passion and deep understanding of the subject, he was able to explain complex concepts clearly while also introducing innovative approaches. Although his presentation was rich in content and full of slides, this density of information highlighted the depth of his vision and his persuasive power. Artem has the ability to captivate his audience with his open and engaging style, effectively leading them through the material. He demonstrates not only remarkable technical expertise but also the skill to communicate his message in a way that sparks reflection and encourages discussion. We sincerely thank Artem Boiko for his valuable contribution and look forward to future opportunities to benefit from his knowledge and visionary perspective.

Exceeded Expectations with Comprehensive Features

I love how OpenConstructionERP goes beyond my expectations and is as complete as it gets for open-source apps. [...] The most valuable aspect for me is the cost data feature, which is typically hard to find. Additionally, the initial setup was very easy.

What your team gets

Reports in minutes, checks that run themselves, data your AI can read.

Revit and IFC reports that used to take me almost weeks to create are now updated in just a few minutes. I was able to quickly understand what the DataDrivenConstruction did and thus extend and modify it to fit projects. The DataDrivenConstruction team showed me examples of blocks and scripts that can automatically generate PDF, XLSX, and DOCX files that mark errors/defects in the model. Additionally, we also now do automatic checks for IFC structure, file naming, etc.

Daniel GloberBIM Manager · SCHOLZE-THOST GmbH

As a data scientist, I use data every day in every topic and field and think that data can appear in one format to make it easier to use and explore. After I tried the DDC converter, it became the only solution for me to manage and convert all BIM documents. Thanks to DataDrivenConstruction, I can now work with all IFC and Revit files automatically without having to upload files to the server.

Mohamed TouatiPrincipal Data Scientist · Pixemantic

Great experience: Until now, I used to open IFC files in Blocknote to check the parameters and their structure. Thanks to the DataDrivenConstruction converter I can check the parameters and see their structure directly in MS Excel in an orderly and SMART way, amazing!

Open cost database · CWICR 251

A price reference your estimators and your AI can both read.

OpenConstructionEstimate is a structured database of construction work items and the resources behind them. Instead of a flat price per position, it stores how the work is built, so you can price it for your region, check an estimate line by line or let an agent match a BIM model to costs.

national cost bases
  • Resource-based

    Every work item is broken into labour hours, materials and machine time. Norms stay fixed, prices are regional.

  • Built for AI agents

    Ships with a vector snapshot for semantic search, so an agent finds “concrete wall 25 cm” without exact codes.

  • Your formats

    XLSX, CSV and Parquet for Excel, BI and Python, plus a free REST API and Linux packages.

Open source

Built in the open, trusted by thousands.

We publish what we build. Engineers, estimators and developers worldwide use, fork and extend our repositories, so you can audit every line before you trust it with your data, and you are never locked in.

Readers on the book

14 reviews from professors, BIM managers and editors.

“Data is the new oil" as they say, so its prospectors or miners should have the right tools and mindset to extract value from this 21st century resource. The construction industry has for too long been on the slippery slope of "3D information" based processes, whereby project delivery is based on someone else's baked information (e.g. they already plotted the pie or bar chart) whereas the underlying "data" (e.g. the raw spreadsheet) is capable of delivering much more, especially because multi-data fusion and AI bring unlimited potentials. If you are delivering (or teaching/researching) construction, this book is your best - and so far only - resource for navigating the data-driven world we have found ourselves.

Dr. Zulfikar AdamuAssociate Professor of Strategic IT in Construction · LSBU, UK

The "DATA-DRIVEN CONSTRUCTION" by Artem Boiko is a comprehensive work that fills a gap in the "modern" construction industry. It offers valuable insights into both the basics and advanced applications of data in construction. Artem also presents an interesting approach to handling data in construction and shows how it can be used. It is a successful presentation of the various possibilities that data can offer in construction and provides practical guidance and examples. As such, it is an absolute recommendation for anyone involved in the use of data in the construction industry.

FAQ

Good questions.

Something else? Ask us directly

Where do we start if our data is spread across many tools?

With a short assessment. We look at the systems you already use (CAD/BIM, ERP, estimating, Excel, PDFs), find where the same data is entered twice or gets lost, and rank the fixes by effort and payoff. You get a written roadmap your management can sign off, with the first quick wins your team can start on right away.

How quickly will we see results?

Usually on your own files during the first sessions. We reuse pipelines, AI-agent skills and modules that already work at other construction companies, so we do not build from zero. Larger integrations are split into steps that each deliver something your team can use.

How is the work priced?

There is no price list, because no two companies start from the same place. After a free intro call we send a written proposal for your scope: what we deliver, how long it takes and what it costs. You pay after the agreed result is delivered.

Do we have to replace the software we already use?

No. We connect what you have through open formats and interfaces, and only suggest replacing a tool when it blocks your data. Everything we build runs alongside your existing CAD, ERP and estimating software.

How do you handle data security and confidentiality?

Everything we build is offline-first and runs on your own infrastructure. For AI we can use local language models, so drawings, prices and even prompts stay inside your network. We sign an NDA on request before we look at any project data.

Where does AI really help a construction company today, and where not yet?

It helps wherever structured data already exists: quantity takeoffs, model checks, classification, matching BOQ positions to cost data and answering questions across project documents. It does not replace engineering judgement. We set up agents with clear limits and a person who signs off the result.

Who owns the result and the code?

You do. Custom pipelines, agents and modules are handed over as code with documentation. Our platform OpenConstructionERP is open source under AGPL-3.0, so there is no vendor lock-in.

What does a workshop look like, and who should attend?

One or two days, on-site in Germany, Austria and Switzerland or remote worldwide, in English or German. We work on your own projects: first how the data flows today, then hands-on practice with Python, n8n or AI agents. Typical participants are BIM managers, estimators, project managers and the people who run digital transformation.

Will our team be able to run it without you?

That is the goal. Every project ends with a handover: documentation, a training session for the people who will run it, and an optional support plan for updates and questions.
