Project Overview

The project involved the remediation of a decommissioned sand-mine of approximately 120 hectares which had been overrun with pest flora and fauna species. Neumann Contractors was commissioned by Logan City Council to undertake the works involving the rehabilitation and revegetation of the area.

A key objective of the project was to create a milestone development which provided a high level of commercial facilities whilst also improving the environmental value of the site. The retention and regeneration of the ecological characteristics of the site to its natural condition along with the provision of an area of superior community amenity and aesthetics was crucial.

The area now includes lakes, wetlands, tributaries, ponds, remnant vegetation and provides major habitats for native frogs, waterbirds and large tree dwelling mammals. The project was undertaken in two main works areas; the Mixed Industrial and Business Area and The Parkland and Wetland Area.

Best practice community engagement was maintained throughout the life of the project. Local business and government concerns were promptly addressed in every stage of the project.
