I contacted JHA Australia with an enquiry and the response I received was very professional and helpful. Unfortunately what I was after wasn't within the scope of JHA Australia's works. Despite this, not only did the general manager Rowan still respond, he also provided recommendations of others who may be able to assist. Honest, responsive, helpful and professional

As a business who often requires external engineering for some aspects of our fabricated client offer, it is refreshing to find an engineering service that delivers. I have been let down by countless engineers for time frames in the past but JHA delivered in a speedy and efficient manner with solutions that weren't over the top and didn't blow the job budget out. I will be engaging JHA as our "go to" engineering solution going forward and I look forward to a positive and beneficial business relationship. Thank you for the great experience guys!

Rowan at JHA was extremely helpful with information and advice regarding an engineered and designed retaining wall. He was very knowledgeable and informative as well as prompt with his replies. Although we decided not to proceed with our project we wouldve had no hesitation in using JHA for the job and we recommend them highly.

I called up JHA to ask for advice after putting my home up for sale and the buyers building and pest highlighted a specific item on the list which was a source of confusion. Instead of charging me for their time, they asked me to send through what I had to their senior engineer (Tim) who kindly looked over the report. The report wasn't informational enough, so they asked for some photos as well.
JHA could have easily charged me for their time and I have no doubt I took a bit of it, but they didn't charge me anything for which I am grateful. They went above and beyond for me and if I ever need
