Your tender process easier, more secure and sorted more quickly

The Autumn 2025 release is packed with new features that help general contractors save time, collaborate better and make more informed decisions. Discover how our innovations elevate your tender process.

AI-Powered Quotation Insight: Better, Faster Decisions

You already compare quotes by price. But what about deviations, assumptions, exclusions? This AI tool will help you highlight these insights clearly and quickly.

Lower risk of unexpected costs.

Speed up quote reviews and comparisement.

Build transparent reports for your team or client.

New Search Experience: Fewer Clicks, Better Matches

The search page in 12Build has been renewed. You now see more profiles at once, navigate  more smoothly, and manage communication from a single screen. The search bar has also been improved: type a few keywords and receive instant smart suggestions.

Spend less time searching and comparing.

Instant visibility of relevant companies.

Detailed company profiles with information about expertise, references and partnerships.

Publications: Find the Right Specialists, Faster

Still looking for the right subcontractor or supplier for a specific part of your project?
With Publications, you can easily publish parts of your project within 12Build. You decide what to share, with whom, and until when. Additional data like descriptions and deadlines help attract better responses and give you more control over planning.

Faster contact to suitable subcontractors and suppliers.

More market insights and price transparency.

Improved preparation for procurement decisions.

SharePoint Integration: Work with the Right Files

Are you using SharePoint for central document management? Good news: you can now link documents directly between 12Build and SharePoint. That means no more duplicate uploads or versioning confusion.

Fewer errors due to outdated files

Save time when sharing information.

Work more efficiently as a team.

More control over project phases and safety

Documents expire faster
Project documents are now available to external users for only 1 month by default. After that, all project information, including documents, will of course remain accessible in their (free) 12Build environment. This gives you more control over who has acces.


Structuring project phases
Is your procurement department already working in 12Build? It is easy to transfer requests and quotations from the calculation phase to the next phase. This prevents duplication of work between calculations and purchasing.
