Bill of Quantities

A major new release is the Bill of Quantities. The functionality contains the option to add budget rules to a quotation request. The budget rules allow the general contractor to be more specific about what information they want to receive within a subcontractor's quotation. It saves subcontractors time and they can make better quotations, because they receive more specific requests.

Once the subcontractors have completed the indicated budget rules, the general contractor can easily compare them. The comparison takes the different specified requirements and prices per subcontractor into account. 

Communication overview

With the communication overview in 12Build, all project communication is centralized and available in real-time. Receive instant updates on status changes, new documents, and more.

Thanks to the clear overview and real-time updates, collaboration becomes more efficient, and you can quickly respond to changes. Whether it’s managing documents or tracking progress, the communication overview ensures that everyone involved always has access to the right information.

Bid Board

With the Bid Board in 12Build, you can manage all your quotation requests in one central place. Whether a request comes in through 12Build or externally, you can easily add and organize it, ensuring full control and clear oversight of your quotations.

New requests start in Received and then move through the following stages: In Progress, Calculation, Sent, Rejected, and Awarded.

Changelog February 2025.

Improvements

  • We've implemented some technical improvements that have made the overall platform faster, resulting in quicker page load times.
Bug fixes
  • Our URLs tried something new by merging work categories. We gave them commas, so they are separated correctly again.
  • We fixed the problem where reminder emails for multiple work categories within a project contained incorrect links.
  • Messages sometimes ended up in the wrong project. We have ensured that they now end up in the correct place.
  • The work category filter in Publications was taking a little too much charge and overwriting other active filters. Now you can filter as you should again!
  • We fixed a bug in Publications that sometimes caused a message to be sent to a large number of subcontractors. Now no more email spam, unless you really like to keep sending the same message.
