Dam and SpillwaysDAM CONSTRUCTION
RIX have recently completed two large dam projects. RIX have the experience to advise and assist in the design of spillway walls using faster and cheaper shotcrete construction rather than traditional form and pour. DAM CONSTRUCTION - SPILLWAYSProject: Shannon Creek Dam
Client: Department of Commerce
Principle Contractor: Leighton
Total area: 3500m2
Design: 300mm thick Shotcrete up to 11m in height
Completed: 2008
  In order to reduce programme and cost RIX worked with Leighton and their client the Dept of Commerce to gain approval for shotcrete as an alternative to conventional form and pour concrete to the walls in the Spillway section of the Dam. Upon completion of preconstruction testing approval RIX installed all reinforcement and 300mm thick and finished 3500m² of shotcrete walls up to 11m high.
As staged excavation on the approach roads to the Dam and to the spillway floor level (up to 50m deep) proceeded Geotechnical design required that large areas required permanent support. Around 4000 Rockbolts were installed whilst meshed and shotcrete areas totaled around 7000m2
 
DAM CONSTRUCTION - SPILLWAYSProject: Hinze Dam
Client: Queensland Bulk Water Supply Authority
Principle Contractor: Thiess
Total area: 600m2
Design: 1m thick Shotcrete up to 14m in height
Completed: 2008
RIX assisted in design, planning and ultimately construction of the curved and finished panel section shotcrete walls.
