Dundonnell Wind Farm Powers Ahead

Construction is well underway at Tilt Renewables, Dundonnell wind farm, a 336 MW project located in southwest Victoria. Vestas are the EPC for the project, with Zenviron delivering the balance of plant. icubed has played a major role in the project, being responsible for the investigations and design of the project civil works, inclusive of the turbine foundations, significant external road upgrades, over 50 km of internal roads and the electrical substation facilities. icubed’s Marcus Palmer is based on site, providing quality control surveillance and interfacing with our project design team based in both our Brisbane and Melbourne offices.
The first turbine foundation pour was successfully completed in late July, which marked a significant milestone for the project. Due to the variable conditions across the project area, icubed have designed three different foundation types for construction. The largest comprises 680 m3 of concrete, which is the largest foundation design completed by the icubed structural engineering team. The first of two massive power transformers has also completed it’s 4 day journey to site and was positioned on the foundations designed by our substation team. Its partner will be delivered to site in the near future, with the pair separated by an 8.5 m high, reinforced concrete fire wall.
The construction of access tracks and hardstands has been progressing well, despite the challenging conditions and persistent wet weather so far this winter. The challenge of high strength, near surface basalt rock, has created an opportunity for the production and use of high quality pavement materials from within the project. This has allowed for civil construction to proceed without the need for importing pavement material, and by conclusion of the project will have seen over 12,000 semi trailer movements avoided on the local road network.
icubed looks forward to continuing their involvement in the implementation of the design of Dundonnell wind farm as works continue to progress on site.
