True to our collaborative and multidisciplinary approach, engineering disciplines have been a part of our in-house offerings since 1977. Working closely with you and the Larson & Darby Group design team, our engineers determine the most appropriate and sustainable systems for your project, from structural, mechanical and electrical to plumbing, and fire protection.

Our extensive experience in balancing quality, scope and budget allows us to recommend the most cost-effective, state-of-the-art systems that provide safe, comfortable, controllable and easily maintained environments.

Whether it’s a hospital, school, church, or restaurant, or something as complex as an aerospace super-profiler, manufacturing test lab, airport terminal or waste water treatment facility, we have been privileged to provide engineering services for clients worldwide. Thanks in part to our in-house engineering expertise, we enjoy longstanding relationships with many organizations, including Alstom Power, Boeing, Cadbury Adams, Caterpillar, Danfoss Drives, Exelon, Hamilton Sundstrand, John Deere, Siemens, United Parcel Service, University of Illinois, Woodward, and Wrigley.
