We have collaborated with Derek Mackenzie on challenging sites which required technical expertise and ability to problem solve. We found Derek to be a fantastic collaborator who communicated professionally and delivered on time. I have no hesitation in recommending Derek to others.
Derek approaches his work with confidence and has the technical abilities to match. On a recent job, Derek was responsible for hydrological modelling to size a leachate dam and irrigation area for an organics processing operation. Derek was professional throughout and client liaison skills were exceptional. Derek’s report was delivered on time and on budget and written to a high standard.
I have used Derek for a number of residential developments within NSW and found the knowledge, service and innovation of the plans to be of exceptional quality. Working with Derek was easy and efficient and I will definitely be recommending this company to my existing and future clients.
