What’s New in 12Build

On this page, you will find more information about the latest features, improvements, and developments at 12Build. Everything we do has one goal: to offer more control, transparency, and trust in every collaboration.

Publications

Finding new and reliable partners for your projects can be a challenge. Often, you stick to your existing network, even though the market is full of interesting companies you haven’t met yet.

That’s why we developed Publications. With it, you can make (parts of) your project visible to the market, allowing suppliers and subcontractors to find you — instead of the other way around. This way, you discover new collaborations, gain insight into current prices, expand your network, and work with partners who match the quality and reliability you’re looking for.

Key features:

  • Publish complete projects or specific workpackages in 12Build

  • Decide what you share and who can see your project

  • Automatically receive responses from relevant suppliers and subcontractors

Coming: Compare quotes with AI

Comparing quotes often takes unnecessary time. Every subcontractor submits their quote in a different format, information is scattered across multiple documents, and exclusions are easily overlooked. The result: lots of manual work and a risk of missing important details.

Soon, the AI quote comparer will take that work off your hands. This tool helps you make faster and more objective decisions because it:

  • Automatically detects differences between quotes
  • Highlights exclusions and deviations
  • Compares offers on more than just price 

This gives you a clear overview of what each party offers, where the risks lie, and which details truly make the difference. Within minutes, you’ll see which quote best fits your project — well-founded, clear, and without surprises.

New search page

Searching is now even faster and smarter

You want to quickly and confidently select the right subcontractors and partners. That’s why we’ve redesigned the search page and company profiles.

Compact company profiles now slide right into view, featuring clear references, specialisations, and a brand-new “Preferred Partners” tab. This means you no longer have to leave the search list — keeping the full overview right at your fingertips.

With smarter suggestions, clear filters, and more relevant profiles per page, you’ll work much more efficiently.
