Dams and Weirs

Built in 1982, the weir required retro-fitting of channels to allow for fish migration in the Burdekin Basin. Fish migration allows fish to travel up and down stream between dams and weirs. Super City Concrete Cutting were engaged to cut the channels for this project.

Built on the Lachlan River and completed in 1935, the dam can hold nearly twice as much water as Sydney Harbour with 1.2million ML. At its highest point the structure is 85m (more than a 25-storey building) with a base measuring 304m (equal to 15 cricket pitches). Super City Concrete Cutting were engaged on the NSW project 1B Spillway Chute Wall Raising Project to core drill large quantities of up to 60mm diameter to depths of up to 1000mm. The work was difficult in nature due to all works being at heights from 6m to 15m from the spillway slab with access either by boom or scissor lift.

Ross River Dam, 20km SW of Townsville was built in the 70s and is the longest dam in Australia with its embankment wall running 8.4km and a catchment of 750m2. Supercity Concrete Cutting were contracted to lower the existing spillway and install dam gates to help control downstream flow and water storage levels. Principal contractors were John Holland and Macmahon.

As Gleeson's Weir, located on the Ross River in Queensland, did not meet current dam safety regulations, Super City Concreting was engaged to cut 250mm from the top of the weir surface as well as coring and dowelling the existing wall in readiness for forming and pouring approximately 1500m3 mass and reinforced concrete.

Located in central Queensland, Fairbairn Dam was built for irrigation in 1972.
