Nemetschek Strikes Deal to Acquire Thoma Software Firm HCSS

Nemetschek SE, a Munich-based engineering software firm, has agreed to acquire Heavy Construction Systems Specialists (HCSS), a U.S. construction management software provider, from private equity firm Thoma Bravo. The deal expands Nemetschek’s Build segment, strengthening its portfolio in construction technology and digital workflow solutions for heavy civil and infrastructure projects. The acquisition, announced in April 2026, follows earlier Bloomberg reports and aligns with Nemetschek’s strategy to consolidate specialized software providers in the AEC (architecture, engineering, construction) sector. HCSS, known for its fleet and equipment management tools, will integrate into Nemetschek’s existing suite, enhancing capabilities for large-scale construction firms and public infrastructure clients. Financial terms were not disclosed, but the move underscores Nemetschek’s push to dominate high-margin software niches within the global construction tech market.
