Thoma Bravo Forges Construction Tech Giant in HCSS-Nemetschek Deal

SAN FRANCISCO, CA – April 13, 2026 – In a move set to reshape the global construction technology landscape, private equity firm Thoma Bravo announced today it will combine HCSS, a leader in heavy civil construction software, with the Nemetschek Group's Build & Construct segment. The deal creates a new industry powerhouse, merging complementary strengths to offer a comprehensive suite of tools for the entire building lifecycle.

Under the terms of the definitive agreement, HCSS will join a portfolio that includes other well-known construction software brands like Bluebeam, GoCanvas, and Nevaris. The German-based Nemetschek Group will hold a majority stake of approximately 72% in the newly combined segment, while Thoma Bravo, which acquired HCSS four years ago, will retain a significant 28% minority share, signaling its continued confidence in the venture's growth potential.

The transaction, pending customary regulatory approvals, is expected to close in the second half of 2026.

The Making of a Market Titan

This strategic combination unites HCSS's 40-year dominance in the heavy civil construction sector with the broader architectural, engineering, and construction (AEC/O) prowess of Nemetschek. HCSS is renowned for its flagship products HeavyBid and HeavyJob, which are staples for estimating and field operations on major infrastructure projects. Nemetschek’s Bluebeam is considered the industry standard for digital blueprints and collaborative markup.

"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," said Steve McGough, President and CEO of HCSS. "Our strengths in heavy civil construction software complement the Build & Construct segment's existing solutions, creating a broader, more powerful platform for customers."

The merger is designed to create a seamless, end-to-end workflow for clients, from initial design and bidding to project execution and management. For Thoma Bravo, the move represents the culmination of a successful investment period.

"When we considered ways we could leverage HCSS' incredible culture and performance at a greater scale, we identified this combination with Nemetschek's Build & Construct segment as a once-in-a-lifetime opportunity," said A.J. Rohde, a Senior Partner at Thoma Bravo. "Both organizations are leading the global AI revolution in construction design, planning, execution and collaboration, and together they will have the platform, talent, and ambition to continue setting the pace for the entire industry."

Reshaping a Competitive Landscape

The deal lands in a fiercely competitive and rapidly growing market. The global construction software sector, valued at over $14 billion in 2024, is projected to climb towards $20 billion by the end of the decade as the industry accelerates its digital transformation. This merger positions the new Nemetschek-led entity to more aggressively challenge established players like Autodesk, Procore, Oracle, and Bentley Systems.

While the market is fragmented, competitors have carved out significant niches. Autodesk Construction holds a substantial market share in construction management, while Procore has become a dominant platform for project management. The combination of HCSS's deep penetration in the U.S. heavy civil market—where its customers win 75% of work across 50 Department of Transportation markets—with Bluebeam's vast user base creates a formidable competitor with a uniquely comprehensive portfolio. This synergy allows the new entity to cross-sell solutions to a combined customer base, covering everything from horizontal infrastructure to vertical building projects.

The financial muscle behind the deal is substantial. HCSS reportedly generated approximately $215 million in revenue in 2025 with an impressive 40% EBITDA margin. While Nemetschek will take on additional debt to finance the transaction, the acquisition is seen as a strategic investment to capture a larger share of the projected $12 billion market it is targeting by 2028.

A Blueprint for Future Infrastructure

This merger is strategically timed to capitalize on powerful global trends. Aging infrastructure in developed nations, massive government spending initiatives on transportation and utilities, the global energy transition, and rapid urbanization are all creating unprecedented demand for more efficient and technologically advanced construction solutions. The combined company aims to be the go-to provider for the firms rebuilding the world's infrastructure.

The technological vision extends beyond simple integration. Leaders from both companies have emphasized a focus on accelerated, AI-based innovation. By combining vast datasets from HCSS's field operations with Bluebeam's design and collaboration data, the new entity is poised to develop powerful AI tools that can optimize bidding, improve project scheduling, enhance safety, and reduce costly rework. This aligns with Nemetschek's broader strategy of championing open standards and digital twin technology to create a more interconnected and intelligent construction ecosystem.

"This transaction brings together the two most innovative products in construction technology to build a global industry powerhouse," commented George Jaber, a Principal at Thoma Bravo. He noted HCSS's standard-setting tools for estimating and field operations and Bluebeam's unmatched position in digital drawings, creating a powerful combination.

For customers, the promise is a more unified and powerful platform that bridges the chronic communication gap between the office and the job site. The integration aims to deliver real-time data and actionable insights to all stakeholders, streamlining workflows and enabling more informed decision-making across the entire project lifecycle.
