Water Dam
| Burnett Catchment Water Infrastructure Project, | ||
Map showing the location of the Burnett Catchment area within Queensland. |
Before dam construction commenced, two stretches of roadway were upgraded to improve access, 16km of the existing roadway to the dam site and 6km serving the approach to Eidsvold Weir. |

The Burnett Catchment area is an important site for wildlife; many of the shallow vegetated bodies of water like this one are likely to disappear when the inevitable reduction in flow occurs. |

Construction work on the dam began in November 2003 and progress to the following August suggests that it is on target for the scheduled completion date in October 2005. |
The project has met with objections on environmental grounds - the Burnett River is one of the only two habitats in the world for the rare Queensland Lungfish (Neoceratodus forsteri). However, the project has also received much support from a variety of sources. |

| Lower Kihansi Hydropower Dam and Reservoir Project | ||
The Lower Kihansi Hydropower Project contract called for the building of an underground power station cavern which has an initial installed capacity of 180MW in three units and a potential ultimate installation of 300MW in five units. |
The Lower Kihansi hydropower project, located 450km south-west of Dar Es Salaam and 80km south of Iringa in Tanzania, includes the construction of a concrete gravity dam with a height of 25m and a length of 200m, which creates a reservoir with a storage volume of one million m3. |

Mortar spreading and feather edge treatment applied to the concrete. The Tannur Dam was the first in the Middle East to be constructed with RCC and used a sloped layer method, never before seen outside of China. |

Sketch-diagram of the sloped layer method. This approach involves building up multiple layers, laid successively to build up one single super-layer sloped at an incline of between 1:10 and 1:20, which maximises structural integrity. |
