Gavin and the team at GDW Engineering provide invaluable support in delivering large scale renewable projects in which I have been involved. GDW was able to offer high quality design, highly competent site supervision and most importantly, an attitude which focused on a "best for project" outcome. Would highly recommend GDW and look forward to working with them again.

GDW added a timely and necessary injection into our project providing turn key services ranging from project management down to site supervision. They offer a cost effective solution whilst at the same time completing any deliverable at the highest quality maintaining full compliance to the site specifications and Australian Standards. I would not hesitate to engage GDW again and look forward to working with the company at the next opportunity.

I purchased a new commercial property without an electricity connection and had no idea what to do. I was given GDWs number as someone to call to sort things out. Service and friendliness has been exceptional without fault. I highly recommend Gavin and his team for upfront expertise, honesty and value.
