Summary
Thoma Bravo has agreed to merge HCSS, a portfolio company it has held for four years, with Germany-based Nemetschek Group's Build & Construct division in a transaction designed to establish a scaled global software platform for the construction sector. Under the agreement announced April 13, 2026, Nemetschek will retain approximately 72% ownership of the combined segment while Thoma Bravo maintains a 28% minority stake. The transaction is subject to customary regulatory approvals and is expected to close in the second half of 2026.
HCSS, headquartered in Sugar Land, Texas, specializes in heavy civil and infrastructure construction software and serves more than 4,000 companies ranging from small firms to billion-dollar general contractors. The platform supports over 550 employees and has built significant market penetration across US Department of Transportation projects and infrastructure markets since its 1986 founding. During Thoma Bravo's four-year ownership, the company expanded its product suite to include core platforms such as HeavyBid and HeavyJob, with expansion into adjacent sectors including utilities.
The combination brings together HCSS's infrastructure-focused capabilities with Nemetschek's existing Build & Construct brands—Bluebeam, GoCanvas, and Nevaris—creating an integrated suite of tools spanning the full construction lifecycle from planning and design through execution and field operations. According to Nemetschek, the transaction deepens the group's vertical AI leadership in architecture, engineering, construction and operations (AEC/O) by combining HCSS's proprietary lifecycle data and AI expertise. The enlarged platform is intended to enhance cross-functional collaboration between office and field workflows while accelerating development of AI-enabled capabilities.
The timing aligns with structural demand drivers in construction technology including substantial infrastructure spending, energy transition investments, urban development initiatives, and modernization of aging assets. Nemetschek's decision to maintain significant balance sheet flexibility through the 72% majority structure underscores its capacity to pursue continued organic and acquisitive growth across its broader portfolio while capturing synergies from the HCSS integration.
