The Kleinfelder Blog

Kleinfelder is proud to announce its rise to #20 on Trenchless Technology Magazine’s 2025 Top 50 Trenchless Engineering Firms list, up from #25 in 2024. This achievement reflects our client’s confidence in our engineers and continued growth in the trenchless market.

Kleinfelder’s upward trend demonstrates our ability to deliver innovative, cost-effective solutions while expanding our capabilities in an increasingly competitive service.

What Sets Kleinfelder Apart

Where other firms rely on subcontractors for trenchless expertise, Kleinfelder delivers a fully integrated team—mechanical, geotechnical, and civil engineers working together. This integrated expertise means anticipating needs, proactive solutions, fewer delays, and faster decisions that anticipate every angle—from soil conditions to structural integrity to mechanical performance.

Our engineers:

• Do not scramble for outside help – Kleinfelder understands requirements from kick-off, avoiding surprises.
• Provide a broader perspective and efficiency—trenchless technology is a tool, applied strategically when design challenges arise.
• Lower client and project risk—understanding permitting, underground conditions, and project requirements from inception.
• Seamlessly integrates—trenchless is a core element of our design toolkit and we use it to regularly solve challenges. It’s not an “add-on” or an afterthought.

Driving Success

Our trenchless team leverages advanced techniques—such as lining sewers beneath highways and horizontal directional drilling under sensitive ecosystems—to solve complex infrastructure design and construction challenges. These methods minimize environmental impact, reduce risk, and ensure project efficiency.

We also invest in employee training and development, offering an annual trenchless training program to keep our engineers at the forefront of industry innovation.

Why It Matters

For our clients, this ranking is more than a number, it’s a recognition of Kleinfelder’s abilities.  Kleinfelder delivers:

• Reduced environmental and public disruption through trenchless solutions – avoiding open-cut excavation and reconstruction.
• Lower project risk by applying proven expertise to every design.
• Cost savings and schedule confidence through approaches that streamline permitting and construction.
• Prioritize client goals and collaborate to mitigate community impact.

As Gus O’Leary, Trenchless Technology Community of Practice Lead, notes:

“At Kleinfelder, trenchless is more than a method—it’s a mindset. By blending mechanical, geotechnical, and civil expertise, we deliver solutions that anticipate complexity and redefine efficiency. Integrated expertise means smarter designs, faster decisions, and projects built for the future.”
