Private equity firm Thoma Bravo said Monday it has reached terms to integrate HCSS, a specialist in heavy civil construction software, with the Build & Construct segment of Nemetschek Group, a software provider for architecture, engineering, construction and operations markets.
Under the proposed ownership split, Nemetschek SE would own approximately 72% of the Build & Construct segment shares and Thoma Bravo-managed funds would retain about 28% as a minority shareholder.
The combined organization will bring HCSS together with established Build & Construct brands already within Nemetschek’s segment, including Bluebeam, GoCanvas and Nevaris.
During the four years HCSS was owned by Thoma Bravo, the company broadened its platform and enhanced its core products, notably HeavyBid and HeavyJob. HCSS’s software is deployed on infrastructure projects, with the company reporting that its customers secure 75% of work across 50 U.S. Department of Transportation markets and submit 40% more bids than competing contractors.
Steve McGough, President and CEO of HCSS, commented on the plan, saying, "Becoming part of Nemetschek’s Build & Construct segment will unlock tremendous opportunity for HCSS and we’re thrilled that Thoma Bravo will continue alongside us."
A.J. Rohde, a Senior Partner at Thoma Bravo, said the combination with Nemetschek’s Build & Construct segment represents a significant opportunity for both organizations.
The parties expect the transaction to close in the second half of 2026, though the timetable remains subject to regulatory approvals and other customary closing conditions.
Financial advisory roles in the transaction are assigned as follows: Deutsche Bank Securities Inc., Citi and Centerview Partners LLC are advising Thoma Bravo, while J.P. Morgan is acting as financial advisor to Nemetschek Group.
Context and implications
The deal combines a niche heavy-civil software provider that reports strong win rates in U.S. Department of Transportation markets with a broader construction-software portfolio. The blending of HCSS’s product set - including HeavyBid and HeavyJob - with Nemetschek’s Build & Construct brands is positioned as a way to expand product reach within construction and infrastructure project workflows.
Transaction timing and conditions
Both parties note that closing depends on obtaining regulatory approvals and satisfying customary closing conditions, with an expected completion window in the second half of 2026.
