What do Clients Say about DFE work?

Rockdale City Council: Coolibah Reserve Bardwell Valley
DFE produced a clear Concept design Report for the restoration of a degraded wetland in Coolibah Reserve. This included an explanation of the design aims, a schematic diagram showing key features, concept design section through the wetland, and  advice on species type and numbers to be planted throughout. It also included advice on water levels, scour protection, headwall widening and spillway construction.  DFE were subsequently engaged to undertake all planting works following civil works by another contractor and the result has been a great success. They have also been engaged for the last 12 months to maintain the wetland and associated creek embankment works (also planted by DFE).
Ted Pirola. Senior Landscape Architect, Rockdale City Council

Port Botany, Ecological Maintenance
We found DFE to be a fantastic contractor. The quality of the work is always of a very high standard with direct supervision from management/owners.  DFE were always very conscientious about the work including schedules and cost.

We found DFE to always be willing to work longer hours and provide the needed resources at all times.  DFE worked closely with Baulderstone engineers and environmental manager at all times to ensure the work was completed in a timely manner. 

DFE are one of the most professional organizations I have worked with on large infrastructure projects.  They were always well mannered, polite and hard working.  Their efficiency and professionalism was consistent at all times throughout the project which lasted three years. The uniforms add a nice touch! 
Quentin Pitts, Environmental Manager Baulderstone Pty Ltd (NSW) Port Botany, Ecological Maintenance

I have witnessed “before and after” snap shots of vegetation areas that Dragonfly have worked on and the results after work has been carried are very noticeable, plants are healthy looking and vegetation areas look vibrant and well maintained. The bush regenerating team spend time in ensuring that the work is done to a high standard. No detail overlooked or task too small. Highly recommended.
