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.
