What Syska does

Syska Hennessy Group (legal entity SH Group, Inc.) is an international engineering consulting firm founded in 1928 in New York by Adolf G. Syska and John F. Hennessy. The firm delivers integrated mechanical, electrical, and plumbing (MEP) design, information and communication technology (ICT), architectural lighting, vertical transportation, and commissioning services to enterprise, institutional, and government clients across 13+ sectors including healthcare, aviation, critical facilities (notably data centers), commercial real estate, financial services, education, life sciences, industrial, and civic infrastructure. It employs 650+ professionals across 21 global offices in the United States, the Middle East (Riyadh, Dubai), and Asia (Shanghai, Singapore), and operates a wholly-owned subsidiary, Syska Innovations, which develops proprietary tools such as the Digiduct duct-sizing application.

The firm generates revenue through project-based professional services engagements priced on a quote basis, with no publicly disclosed pricing. Its go-to-market is enterprise field sales targeting owners, developers, architectural firms (e.g., Gensler, HOK), and government entities, supported by a national director of business development and regional practice area directors. Marquee clients include Mount Sinai, St. Jude Children's Research Hospital, NewYork-Presbyterian, JPMorgan Chase, BlackRock, Bloomberg, AIG, Apple, Cisco, Oracle, Harvard University, Columbia University, and major airports such as O'Hare Global Terminal and Orlando International Airport. The firm emphasizes sustainability credentials (85+ LEED professionals) and modern delivery methods including BIM/VDC, digital twin integration, and design-build/public-private partnerships.

Syska is privately held and management-owned, having reaffirmed that status in May 2026 alongside the launch of its Elevate 2035 ten-year strategic plan. The plan emphasizes investment in people, clients and markets, profitable growth, and further geographic expansion, evidenced by the 2025 Riyadh opening and the March 2026 Singapore office addition (its 21st global location). Recent strategic actions include a brand refresh (January 2026), a seed investment in AEC design platform Skema, the appointment of a CHRO, and four associate partner promotions across U.S. offices.
