Syska Hennessy Group

Syska Hennessy Group is the leading global, full-service MEP, information and communication technology (ICT) and commissioning engineer for the government and commercial sectors. With more than 500 professionals across 18 offices, we provide a full range of engineering services for projects of every size and budget: from global headquarters to small office renovations; from the premier healthcare facilities to essential mission critical facilities. We’ve been at the forefront of innovation since the firm was founded by John Hennessy and Adolf Syska in 1928 to design complex, mechanical and electrical systems at the heart of iconic structures. Whether it’s GSA’s super-efficient Los Angeles Federal Courthouse in Los Angeles or one of the world’s tallest mixed-use structures, Lotte World Tower, in Seoul, South Korea, we are the preferred partner for clients who want to create exceptional, smart and sustainable high-performing buildings. We are excited about the future. Our energy and simulation modeling enable clients to predict design implications across entire project life cycles and pursue carbon neutral buildings. By integrating essential systems—lighting, power, audiovisual, security, wireless and the core network—we are designing smarter buildings to improve the quality of the environment for occupants as well as reduce operating costs and environmental impact. We’re adept at design-build and alternate delivery solutions, including P3 and lean construction. Above all, we build long-term relationships with our clients—some of whom we have partnered with for more than five decades—and attract the industry’s best talent through a learning, diverse and collaborative culture. We are Syska.
