Zachry Group

What Zachry Group does

Zachry Group, founded in 1924 and headquartered at 527 Logwood Avenue in San Antonio, Texas, is a privately held (Zachry Holdings, Inc.) EPC contractor serving North American energy, chemicals, power, refining, manufacturing, and industrial sectors. The company employs more than 20,000 people across 35+ offices and 400+ locations, operating through wholly-owned subsidiaries including Zachry Engineering Corporation, Zachry Nuclear Engineering (ZNE), JV Industrial Companies (JVIC), Madison Industrial, Ambitech Engineering Corporation, Computer Simulation & Analysis (CSA), Trillium Advisory Group, Zachry Sustainability Solutions, and Numerical Advisory Solutions.

The company's core product set spans full-service engineering (FEL/FEED, detailed design), EPC project execution, long-term maintenance services, turnaround and specialty services (JVIC), pipe and vessel fabrication (JVIC Fabrication, 200,000+ square feet of indoor space, 5,000+ pipe spools per month), procurement, and advanced analysis and simulation. Proprietary technology includes GOTHIC, RETRAN, VIPRE, PROTO Tools, and RADTRAD-NAI software developed with EPRI sponsorship, plus AI/ML and digital twin capabilities delivered through Numerical Advisory Solutions. The business model is enterprise project-based: revenue is generated through negotiated EPC contracts (multi-year), long-term managed maintenance agreements, professional engineering services, turnaround services, and fabrication hardware sales, with pricing not publicly disclosed.

Zachry serves a concentrated roster of Fortune 500 customers including Golden Pass LNG (Qatar Petroleum/ExxonMobil), Freeport LNG, Cameron LNG, Chevron Phillips Chemical, ExxonMobil, BASF, Dominion Virginia Power, Exelon Generation, Duke Energy, OPPD, LG&E, Calpine, X-energy, TerraPower, Natura Resources, and NET Power. The company executed major capital projects such as Warren County Power Station (1,346 MW), Mill Creek Generating Station retrofit (1,472 MW AQCS), Freeport LNG three-train facility (13.9 million tons/year), and Golden Pass LNG (approximately 16 million tons/year). In May 2024, Zachry Holdings filed for Chapter 11 bankruptcy primarily due to financial challenges on the Golden Pass LNG project, with the court approving its restructuring plan in February 2025.
