About Us

Argyle Street Hero

Holistic advice that goes beyond structural engineering.

Engineering incorporates both art and science. A truly great Engineer is someone who can move beyond the theory and understand how ideas will work in real life. That’s what we look for in new recruits, and what we expect from our team.

That practicality has underpinned our work since we opened our doors in 1992. Since then, we’ve been delivering successful structural engineering consultancy projects, some with budgets in excess of $80m.

Our flat hierarchy offers our people at every level the chance to make their mark on projects. It’s part of why we’ve grown our business from referrals and repeat business, and why some of our clients have been working with us for more than 25 years.

Melanesian Mission

Comprehensive drawings, better outcomes.

We’re known for the quality and detail in our drawings, none of which are outsourced overseas to be drawn. This, plus our expertise in Base Isolation makes us the go-to firm for sensitive restoration work.
