Our Ethos

At JN, we’ve embraced the ethos of Responsive Engineering.

When we work with you, you’ll witness this in an engineering sense and in the manner in which we engage with you.

To us, being responsive means being ready to go, ready to listen and ready to think deeply about what it is our clients really need.

It also means being ready to deliver - with the right people, processes and technology all in one place. It’s these pillars of behaviour and this approach to our work that truly sets JN apart.

The JN story began over 50 years ago

Trevor Punnett established T.C. Punnett & Associates out of his small home office in Sydney’s South. After 20 years, the company evolved into Jones Nicholson, a multi-disciplinary engineering firm with a reputation for practicality and cost-effectiveness.

Fast forward another 30 years and we’ve grown exponentially in terms of capability and experience. We’re working with public and private sector clients in a variety of industries, and we’ve expanded from our base in Sydney into various regional centres in NSW and most recently into Queensland.

Today JN operates with a team of 80 staff working out of 9 offices in NSW and Queensland.
