Procurement Portal:
All our suppliers register with their master data in this portal and go through our prequalification process. You can work with us as a supplier only once you have successfully completed the prequalification process. The Procurement Portal also enables you to:

  • View and participate in requests for quotations
  • Submit quotations and modify them if necessary
  • Process non-disclosure agreements
  • Find out whether you have been awarded the contract on the basis of your quotation and choose whether to confirm or reject it
  • Maintain master data and update certificates
  • View your prequalification status

Special supplier portal (in German):

This portal is intended for civil engineering suppliers and other suppliers who are commissioned according to the service book. The special supplier portal provides an overview of your orders, contracts and credit notes. You can order and return materials and record deliveries and services.
It is also possible to register and track claims via this tool and to pre-register employees for specific cases.
If you do not belong to this group of suppliers and you do not want to enter claims or pre-register employees, then this portal is not relevant for you.

What are the differences between the two supplier portals?

Our systems are designed to allow suppliers to carry out their own user administration. Unfortunately, we cannot create any additional users for your company.

Please speak to the administrator in your company. This person can easily add users for your company in the system.

The Supplier Code of Conduct is the basis for all working relationships with our suppliers. We take responsibility for our supply chain and ask you to share in that responsibility. In this way, we can minimise the negative social and environmental impact of our business activities. To see an overview of the key points contained in our Supplier Code of Conduct, click here. You can also download the full version as a PDF file here.

What is the Supplier Code of Conduct?
Download image

Yes, because the Supplier Code of Conduct is the basis of our working relationships and a binding part of every contract with suppliers. We expect suppliers not only to follow it themselves, but also to communicate it to their own suppliers, their employees, and their trading partners and to take suitable measures to ensure that it is complied with.
