Monowai Power Station
Commissioned in May 1925 by the Council of the Southland League.
Construction was funded by a high interest loan so cost would have been the constraint. The accepted trade off was the time & the quality was what was enhanced as is was one of the earliest hyrdo dams in NZ & moved NZ from coal to hydro power supply thus needed to meet expectations. It was a unique construction, planned over many years, the deliverable was clear - to produce power to meet increasing demands. -
Waitaki Dam
The NZ Government commissioned the Waitaki Dam in 1928. Constraint was the quality as the end product needed to last generations, time was enchanced as while it was a long project the demands on power still needed to be meet as soon as possble. The accepted trade off was the cost.
The size of project made it unique at the time in NZ, the deliverable was a hyrdo dam to meet ever growing demands for electricity. Planned over several decades & was temporary. -
Roxburgh Dam - Coal Creek
The Roxburgh Dam commissioned 1956 – 1962 by the State Hydro-Electric Department. The constraint was the time as there was alot of pressure to get the project finished. Due to scope creep the accepted trade off was the cost which went well over budget. The quality had to be enhanced as there were concerns over design & durability. Unique as it is the largest concrete gravity dam in NZ, in planning stages since 1947, had a set deliverable 'electricity for the masses' & was temporary. -
Wairakei Geothermal Power Plant
The Wairakei Power Station, commissioned in 1958 as a joint venture between NZ Government & UK Atomic Energy Authority.
Constraint was time as there was an electricity shortage. Quality had to be enchanced as this was at the time a unique world first project. The accepted trade off was cost to allow for new technology development. In addition to being unique & temporary, the project was planned by two countries & had a set deliverable to be the worlds first wet geothermal power plan. -
Manapouri Power Station
Commissioned by the NZ government in 1964 to provide power to the aluminium smelter being built at Tiwai point. Quality was the constraint as the end product had to be fit for purpose for generations & survive in harsh envrionmental conditions. Time was enhanced to provide smelter with power. The accepted trade off was the cost. This is a project as was a unique enginnering feat for NZ at the time, had a clear deliverable, was planned for several decades & was temporary. -
Ross Island Wind Farm
Meridian Energy completed the project to provide Scott Base with a clean renewable source of power. Time was the constraint as they had only the 2008/2009 Anatarctic summer to complete the project. Quality had to be enhanced with equipment needing to withstand the exterme Antarctic conditions. The accepted trade off was cost. This wind farm is unique due to its location & was planned extensively to ensure installation could occur within the fixed timeframe, thus is a project.
