Why DTCE?
Consultants first - Engineers Always
At DTCE, our people make the difference. We’re a team of structural and geotechnical engineers based in Wellington — approachable, collaborative, and committed to designs that actually work on site. Whether it’s a small renovation for a homeowner or a complex new build with an architect, we make the process clear, smooth, and practical from the very first conversation.
You’ll see the friendly faces of our senior team here, but behind them sits decades of technical experience. Across residential, commercial, and industrial projects we’ve tackled seismic assessments, foundation and retaining design, slope stability, and temporary works.
We pair hands-on site knowledge with the latest engineering tools to deliver solutions that are safe, efficient, and built to last.
