The Nemetschek Group, a global leading vertical provider of AI-powered software solutions for the AEC/O and media industries, has announced the completion of its acquisition of Heavy Construction Systems Specialists (HCSS) from Thoma Bravo, effective July 1, 2026.
Founded in 1986 and headquartered in Sugar Land, Texas, HCSS is the leading provider of construction software for the infrastructure and heavy civil sectors in North America, supporting more than 4,000 companies and employing more than 550 professionals. In 2025, HCSS generated approximately US$215 million in revenue, with ARR (Annual Recurring Revenue) growth of approximately 21% and an EBITDA margin of approximately 40%.
HCSS is now part of the Nemetschek Group’s Build & Construct segment alongside industry-leading brands Bluebeam, GoCanvas (incl. SiteDocs) and Nevaris. The combined segment offers a best-in-class portfolio spanning the entire construction lifecycle, significantly expanding the Build & Construct segment’s total market opportunity to an estimated US$12 billion by 2028. With HCSS’s deep domain expertise and proprietary data combined with Nemetschek’s AI capabilities, the combined business is well positioned to drive AI-enabled transformation across infrastructure and construction.
The transaction unlocks significant synergy potential through expanded cross-selling and channel opportunities, enhanced connectivity between office and field workflows and accelerated AI-based innovation across the portfolio. The Nemetschek Group intends to expand the HCSS portfolio beyond North America into key international markets, unlocking the significant growth potential of infrastructure sectors worldwide that are benefitting, among other things, from large-scale public investment.
As part of the transaction, Thoma Bravo has received shares in the Build & Construct segment, holding approximately 28% as a minority shareholder, with Nemetschek retaining approximately 72%. The Nemetschek Group has refinanced all existing HCSS financial debt and liabilities, with an impact of approximately €450 million on its net debt position. The Build & Construct segment remains an integral part of the Group and is managed, controlled and fully consolidated by the Nemetschek Group, with no impact on the shareholder structure of Nemetschek SE.
“Today marks the beginning of a new chapter for the Nemetschek Group and for the construction technology industry,” said Yves Padrines, CEO of the Nemetschek Group. “With HCSS now part of our Group, we have created a truly unique and leading construction AI and technology powerhouse. HCSS brings outstanding technology, an extremely loyal and growing customer base and deep infrastructure expertise that perfectly complements our existing strengths. Together, we are uniquely positioned to serve customers across the full construction lifecycle, accelerate innovation and capture the significant AI opportunities ahead. We warmly welcome the entire HCSS team to the Nemetschek Group.”
