Bridging Tradition and Technology in Geotechnical Engineering

Justin Adams, Engineering Laboratory Manager, Terracon

Justin Adams, engineering laboratory manager at Terracon, is a seasoned expert in geotechnical engineering, field operations and quality control. He began his career as a drill helper at Dunkelberger Engineering and Testing, now part of Terracon, where he gained hands-on experience before advancing to a driller role. He later progressed from lab technician to lab manager, overseeing specialized projects like core splitting for docks and seawalls.

In an interview with Construction Tech Review, Adams emphasizes the importance of strong leadership, hands-on field experience and proactive quality control measures in geotechnical engineering. He also highlights the value of building long-term client relationships and continuously refining expertise to support critical infrastructure projects.

What are your primary roles and responsibilities?

I oversee geotechnical lab operations, quality control processes and specialized testing. I work closely with counties and municipalities, securing contracts and expanding my field expertise. As a quality control manager for multiple local recycled concrete aggregate mines, I play a key role in obtaining DOT certification for these facilities. My leadership has fostered long-standing client relationships, including a partnership that has lasted over 30 years.

Committed to innovation and precision, I remain engaged in the evolving demands of geotechnical engineering, continuously refining my expertise to support critical infrastructure projects.

What are the most significant challenges and trends currently impacting the industry?

One of the biggest challenges has been keeping up with evolving technology. Technology is a cornerstone of efficiency in the construction industry, and Terracon plays a key role in equipping field technicians and streamlining operations with the right tools. Advanced GPS capabilities now allow precise pinpointing of test locations, enabling real-time updates.

“While learning new systems can be challenging, technology remains the most powerful tool in the industry”

The shift to fully electronic reporting, accelerated by COVID-19, has transformed documentation processes. What once required hardstamped reports and physical deliveries is now completed instantly through mobile devices and field notebooks, improving speed and accessibility. Digital tools like laser measurement systems have replaced traditional tape measures, further enhancing accuracy and project efficiency.

Another big challenge is maintaining close client relationships while guiding clients through testing.

Technology has become essential in maintaining these connections, enabling seamless communication through texts, emails and phone calls. In contrast to past reliance on typewriters and walkie-talkies in the field, modern advancements have streamlined client interactions, enhancing efficiency and accessibility.

While learning new systems can be challenging, technology remains the most powerful tool in the industry. It drives faster and more streamlined operations. Keeping pace with these advancements requires adaptability, but the benefits of improved efficiency, accuracy and collaboration are undeniable.

What key technologies or strategies do you anticipate shaping the construction industry over the next 12 to 18 months?

One of the most significant advancements we utilize for safety and efficiency in construction is drone technology. Drones provide real-time aerial imagery, allowing us to monitor large project sites as work progresses. This capability enhances oversight and improves on-site decision-making.

It has also transformed inspections, particularly in hazardous environments. Instead of requiring personnel to climb structures for assessments, drones equipped with specialized cameras and instruments conduct thorough inspections while keeping workers safely on the ground.

Along with drones, we use ground-penetrating radar (GPR) to detect underground utilities before and during projects. GPR enables the independent identification of private utilities, reducing reliance on public records and increasing accuracy and safety for field teams. Pinpointing underground infrastructure in real-time helps prevent costly mistakes and minimizes risks.

Vehicle technology has also evolved to enhance safety in construction. In the past, vehicles had minimal safety features, but today’s models include advanced systems such as automatic braking and enhanced airbag protection. Given that driving is one of the most hazardous aspects of construction work, these innovations provide additional security for field teams, whether on-site or traveling to and from projects.

What sage advice would you offer to a peer or aspiring professional?

Never stop learning and never stop asking questions. There is no such thing as a dumb question. Even with all the technology at our fingertips, it is always valuable to take notes, whether on your phone or with pen and paper. Learn from those who are retiring; they understand both the hard lessons of the past and the realities of the present.

The best advice I can offer is to stay grounded and engaged. Keep one foot in the field, experience things firsthand and avoid relying solely on others for information. Stay hands-on, keep innovating and keep moving forward.

Clear and direct communication is essential. If you cannot take a call immediately, follow up with a text, email or phone call before the day ends. Being upfront and avoiding ambiguity will take you much further.
