Moorabool Windfarm

Moorabool Windfarm project is located 5km south of Ballan, made up predominantly of farmland situated along the Moorabool River. The land itself is rich with cultural heritage primarily in Flora and is home to the Wadawurrung tribe. Located in an environmentally sensitive area, consisting of a designated construction zone with strict access prohibited outside of this area, hence contaminants and waste to be kept to an absolute minimum. made this project extremely challenging.

ACE Civil was involved in the following scope of works:

• Construction of 26km of access track for 50 wind turbines in the Moorabool North Windfarm and 31km of access track for 54 wind turbines in the Moorabool South Windfarm,
• Excavation and preparation for wind turbine foundations as well as the construction of compounds, hardstands and laydown areas (used for the placing, lifting, installing of the wind turbines).
• ACE were also contracted to backfill all foundations with structural fill and finally rehabilitate all areas that overlap into the construction activity area.

ACE pumped almost 10,000m3 of site batched concrete into the tower bases prior to the installation of the steel reinforcing for the tower foundation construction. Approximately 50,000 tons of rock excavated from the wind turbine base digs was crushed. The site material was then re-used in the road pavement for the construction and delivery access tracks.

To help keep pace with an ambitious construction program, ACE utilised drill and blast contractors to assist that almost halved the excavation time frames when dealing with hard rock excavations at the Moorabool Windfarm.
