Pond 1 & 3
'First flush' system formed by separating the inlet zone from the main body of the pond with a low level box culvert and overlayed rock weir; Relocation of existing overflow spillway to the area attached to the above mentioned 'first flush' system; Diversion bund downstream of Pond 1; and Geofabric (Bidim or equivalent) under the rock filled mattresses, rock weir and places with erosion potential (eg downstream of spillway).

Pond 6
Excavation of northeast batter to gain the required volume; Rock filled mattresses at the outfall of diversion pipe; and Diversion bund at the eastern bank and erosion protection geofabric material on the eastern face.

Construction of wetlands and widening of existing creek channel including: Clearing and grubbing, Site earthworks excavation, Treatment of acid sulphate soils, Reinstatement of disturbed areas, and was undertaking for the Redland Shire Council.

This Project was undertaken along a fully commercialised section of busy arterial road.  Some of the key issues included safe management of public through work site, maintaining access to commercial traders, high levels of coordination between various sub-contractors and public utilities, architectural details and finishes.  Project was undertaken within tight budget and time-line constraints.

Due to a revision of Probable Maximum Flood requirement the spillway approach channel training walls of Leslie Harrison Dam needed to be raised.  The existing wall from the edge of the spillway crest to the top of the approach channel batter is a reinforced concrete wall up to 9.2 metres high.  This wall had to be raised by 1 metre to EL 22.35m AHD.  An extension of this wall was required on the left bank for 25.2 m to meed the natural surface.  The right bank wall was to be extended 128.5m and raised to EL 22.35m AHD to encompass the existing control building terminating at the left hand end of the dam embankment. This project incorporated the construction of a block work wall on a reinforced concrete footing including removal and re-installation of a steel framed storage shed.

Construction of a boat travel lift including installation of 450mm octagonal PSC piles, PSC deck units, steel platform and walkway, reinforced concrete retaining walls.  Piles were installed from a barge in the Coomera River.
