Stage 1 of the Snowtown Windfarm is situated along two prominent ridgelines on the Barunga and Hummock Ranges, west of Snowtown, South Australia. The project consisted of the design and construction of turbine footings and associated civil works for the subsequent installation and supply of 47 Suzlon S88 wind turbines.
With parts of the site having been identified as of heritage significance, Aboriginal monitors were present during road construction and excavation of some of the foundations, while measures were also undertaken to minimise dust and prevent the spread of weeds.
Project highlights included:
- Construction of 26km of road for turbine installation and maintenance access.
- Construction of 47 crane hardstand areas for turbine installation.
- Construction of 42 post-tensioned rock-anchored turbine foundations and five gravity-type foundations, totaling 5300m3 of concrete and 700t of steel reinforcement.
- Construction of civil works required for the wind farm substation.
As construction progressed, five further windtower sites were added to the project, bringing the total to 47. Built Environs undertook to hand over all 47 within the timeframe agreed for the original 42 and accelerated the concreting works accordingly. Despite the considerable additional works, the project was completed two weeks ahead of the original 11 month schedule.
