Easily share data between 12Build and KPD.

Thanks to the KPD Tendering and 12Build integration, it is easy to retrieve project data from KPD Tendering to 12Build. Duplicate work is eliminated, and errors are reduced. Once the project has been requested within 12Build, the quotes and bill of quantities can be retrieved back to KPD to continue the process from there.

Request more information About KPD

Everything in one place

Connect 12Build to KPD Tendering and work from a single central point. Project data, schedules, and calculations — always in sync, no manual work needed. Prices change fast. With KPD Tendering, you update your estimate in just a few clicks.

Why integrate?

With the 12Build/KPD Tendering integration, you no longer transfer data by hand. One click shares everything between the two platforms — no errors, no double work. The result is a smooth data flow between procurement, estimating, and project preparation, inside your organisation and beyond.
