STRABAG relies on a clear structure in the Materiality Assessment
The largest construction group in Central and Eastern Europe relies on Materiality Master for more transparency, less manual effort and clear processes in the ESRS-compliant Double Materiality Assessment.
- Largest construction group in Central and Eastern Europe
- Around 86
- 000 employees in over 50 countries
Initial situation: Sustainability as a strategic core component
STRABAG SE generated a turnover of €19.2 billion in 2024, employs around 86,000 people and operates in over 50 countries worldwide. The company covers the entire construction value chain – from building materials production and planning to construction and execution, operation, renovation and demolition. Sustainability is a strategic core component of the company's orientation.

STRABAG has continuously developed the process since the first Materiality Assessment was carried out. Since 2024, the implementation has been fully compliant with the ESRS requirements of the CSRD.
To implement the new reporting obligations, STRABAG was looking for a new digital solution to carry out the Double Materiality Assessment.
Key requirements for a new tool
When selecting a new digital solution, four requirements were at the forefront for STRABAG:
A traceable and consistent history that transparently documents every editing step.
Flexible and differentiated access rights for the various roles involved.
Consistent data storage without version risks, to avoid differing document states.
Efficient, automated documentation that noticeably reduces manual effort.
Introduction of Materiality Master
The switch to the AI-supported Materiality Master Software could be carried out without significant process adjustments. STRABAG was able to use the tool productively immediately, as the onboarding process was smooth and consistently positive. Registration and the creation of additional users were straightforward and without delays. Thanks to the intuitive design of the tool, no extensive training was required, so that productive use was possible immediately.
AI-supported software for conducting the ESRS-compliant Double Materiality Assessment – with the IRO analysis as a central working tool and the materiality matrix for internal and external communication.
Results & Added Value
Through the central bundling of all information in the Materiality Master, STRABAG was able to increase transparency for all involved stakeholders, significantly reduce the risk of different document versions and noticeably reduce manual effort. At the same time, the auditability of the results by external third parties was significantly strengthened.
- More transparency for all involved stakeholders and traceability for external auditors.
- Significantly reduced risk of different document versions through consistent data storage.
- Noticeably lower manual effort and reduced quality assurance effort through automation.
An example from practice: Automation in the tool eliminates a large part of the functionality checks. The effort for quality assurance is thus significantly reduced.
STRABAG also highlights the support from CSR Tools as a decisive factor for the smooth use of the solution.
„We feel very well looked after by CSR Tools. Regardless of whether it's a question or a technical message – we always receive a helpful answer quickly. This reliability makes our everyday work easier and makes a decisive contribution to ensuring that the tool works seamlessly for us."
Strategic importance & outlook
The Materiality Master Software is now an integral component of the annual Materiality Assessment at STRABAG. Materiality Master makes a decisive contribution to fulfilling the CSRD requirements, in particular the ESRS-compliant Double Materiality Assessment.
Customer feedback is valuable here: concrete hints – such as more flexibility in the processing of individual IROs and ideas for the further development of the AI assistant – are already being incorporated into the further development of the software.
„We are very satisfied with the use of the Materiality Master! The central bundling of all information, the automations and the intuitive use make our process enormously easier."
Structure your materiality assessment and reporting – with the same practical solutions that STRABAG relies on.
