Creating Exceptional Environments

Syska Hennessy Group is a global, full-service engineering firm that specializes in MEP, information and communication technology (ICT), and commissioning for the government and commercial sectors. With more than 500 professionals across 20 offices, we provide a full range of engineering services for projects of every size and budget: from global headquarters to small office renovations; from premier healthcare institutions 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. Our people are central to our success: By attracting and training talented professionals from diverse backgrounds, we build creative teams, who transfer their creativity to the built environment. Their work has resulted in complex mechanical and electrical systems for some of the world’s most iconic structures. It has also led to long-lasting relationships with clients who rely on us to create exceptional, smart, and sustainable buildings.

As we approach our 95th anniversary, we are gearing up for another century of innovation. We are perfecting our energy and simulation modeling, which enables us to develop carbon-neutral buildings for our clients and to predict project lifecycles. We’re integrating essential systems — lighting, power, audiovisual, security, wireless, and core networks — to design smart buildings that improve indoor environments, reduce operating costs, and minimize adverse environmental impacts. And we’re continuing to adopt new methods of design-build and project delivery, such as P3 and lean construction.

The future, just like the past, will be filled with change and challenge. Innovation is the constant. We’ll keep applying it to every project to ensure that the built environment reaches its full potential.

We are optimistic.
We are inspired.
We are Syska.

Listening, Learning, Understanding

If there is one thing we have learned in our 85+ years, it is the importance of listening. The information we gain from listening to our clients discuss their goals, missions and the challenges they face every day guides every decision we make at Syska Hennessy.

By listening closely, we learn our clients’ business practices and understand the disruptors that can shape their future. We ask questions and challenge assumptions about the expected path. In doing so, we clear the way to new possibilities and create innovations that help our clients grow into the future.

That is our passion here at Syska Hennessy. Please let us know how we can help you achieve your goals. –>
