Leading the Way in Industry Excellence and Workplace Culture
Starting as a small business providing surveying, municipal engineering, and site development services in North Dakota, Houston Engineering, Inc. (HEI), founded by George Houston in 1968, has evolved into a thriving engineering company with more than 250 professionals across five states, significantly impacting Fargo and beyond. Over 55 years later, President and CEO Gregg Thielman is leading HEI as the company continues the legacy, building both lasting structures in the community and a lasting culture internally. We had the privilege of sitting down with Thielman to discuss HEI’s culture, vision for the future, and more.
An Award-Wining Team
Prairie Business Magazine has listed HEI among the best places to work every year since 2014. This award is based on employee votes, demonstrating the dedication and pride of the HEI team.
At its core, HEI is a talented group of engineers, scientists, technicians, surveyors, programmers, and support staff that work to improve the communities in which they live and work. In doing this, HEI works to ensure that they provide practical and efficient solutions to solve community needs.
HEI functions in six main business sectors: water resources, transportation, municipal infrastructure, environmental, geospatial technology, and surveying and reality capture. Water resources is its largest sector, which includes work for watersheds, flood control, and stormwater modeling. HEI also has an environmental group that specializes in both water quality and environmental permitting, wetlands, delineations, and more. HEI has a growing transportation group that includes designing roads, bridges, railroads, and other infrastructure projects.
“Our Mission is to make positive impacts to communities through collaborative partnerships and innovation,” Thielman said. “We’ve been involved in transformational projects for our clients, including the Fargo-Moorhead Area Diversion Project from the start. Our work includes designing levees, floodwalls, and roads in the area. Our growing footprint includes undertaking flood control in Minot and the Northwest Area Water Supply and Distribution project. These projects will benefit future generations. Additionally, in the Twin Cities, we work on climate resiliency and environmental enhancement projects, serving our clients now and in the future.”
What Sets HEI Apart
HEI puts themselves on the cutting edge of technology by monitoring, exploring, and implementing new technologies like reality capture, augmented reality, and AI. They push industry-standard software to new heights through innovative uses of CAD and GIS, making it easier than ever for users to parse, access, and implement data.
Yet HEI strives to go the extra mile and offer even more to the clients they serve. “We have in-house software engineers that develop software solutions that not only make us more efficient but also serve our clients,” he said. Notably, they developed the ND Roads web and mobile applications for the North Dakota Department of Transportation—an app that is critical for North Dakota travelers to stay up to date on the latest road conditions. HEI also combined their software engineering and environmental expertise to develop MS4Front and DrainageDB, which are now used by county, municipal, and watershed clients throughout the country.
