Summary
The sourcing platform 12Build introduces a new event in the construction sector calendar: the Seasonal Release. During these seasonal updates, 12Build looks back on recent innovations together with customers and provides a preview of what is to come in the coming months.
The Autumn Release 2025 focuses on smarter tendering, AI-driven insights and improved collaboration between all parties in the chain. In three webinars, main contractors, subcontractors and suppliers will be brought up to speed on what's new in 12Build.

Quotations often contain deviations and exclusions that are not immediately apparent. Thanks to new AI functionalities in 12Build, these are automatically recognised. This allows you to make faster and better-informed choices. Less risk, more overview.
The revamped search page, improved company profiles and the option to publish projects (or parts thereof) make it easier for main contractors to quickly select the right partners and monitor the progress of projects.


Subcontractors benefit from smart document navigation, automatic notifications for new projects, and a revamped Bid board. AI summaries of (project) documents also help you determine more quickly whether a project is right for you.
12Build introduces a completely new environment for suppliers, focused on visibility, collaboration and brand presentation. Discover which projects your brand is featured in, easily manage your partners and showcase what you have to offer.
In the Autumn release, the company will present all functionalities in three short 30-minute webinars on Thursday 25 September:
