Who we are
Dictagon is a start-up born from the University of Minho. We bring together construction engineering, product data standardisation and software, and we build on a platform that is already live.
Engineering
Dictagon starts from construction, not from software that learned about construction afterwards. Our experience spans geotechnics, structures and finishes, so a data template reflects how a product is actually specified, tested and declared.
- Geotechnical products and ground works
- Structural and precast elements
- Finishes, including ceramics
Standardisation
We sit in the committees writing the rules, so we read them first hand rather than from summaries. That includes BIM and information management, where the same standardisation effort runs through the product data.
- CEN/TC 442/WG 12: the European working group writing the DoPC standard, prEN 18357.
- CIRPASS-2: expert working groups 1, 2 and 5, and the Community of Practice, on Digital Product Passports.
- CT 197: Building Information Modelling, at IPQ.
- buildingSMART Portugal: the working group on Product Data Templates.
Environmental
We have worked with environmental product data: how EPD indicators are declared, and why they belong in the same structure as performance data rather than in a separate document.
Foundation
PDTs.pt is our foundation: the open, standards-compliant platform for Product Data Templates. It implements ISO 23386 and ISO 23387 for construction products, is live, and has an open API used by industry.
It grew out of the University of Minho, mainly as a CT 197 initiative, and Dictagon's founders worked on it. It was built and is running, not specified and handed over.
