About Us


Indigenous Mining and Civil Australia Pty Ltd (IMACA) was built on the foundations of civil construction knowledge, capability, and experience, realising a vision to build a culturally aware workforce that provides long-term employment for Indigenous Australians.
IMACA is a majority Aboriginal owned company, founded by Fred Taylor and Liam McKinney. The organisation integrates five decades of civil construction experience, delivering concrete, drainage and earthworks projects throughout the state, with a commitment to create a sustainable and prosperous Indigenous business sector in Western Australia

Collaboration with Calroc

Leading civil construction services provider Calroc is a shareholder of IMACA. Specialising in project management, formwork, reinforcement, and concrete, the organisation has forged an integral reputation for delivering successful, high-quality projects throughout Western Australia.
Together the two companies combine their proven engineering approach, and immense industry knowledge, working collaboratively to bring employment opportunities to Indigenous people while delivering quality civil construction projects for their clients.


“The best partnerships aren’t dependant on a mere common goal but on
a shared path of equality, desire, and no small amount of passion.”
Our success is derived from our performance in the field, delivering quality, successful projects across Western
Australia. Our leaders are steadfastly supported by a knowledgeable, experienced, motivated team who are driven to
achieving the goals and visions of our clients.
We are motivated to engage Aboriginal and Torres Strait Islander peoples to join with us, working together and learning
to be leaders in the industry, and their communities.
IMACA is focused on making a difference, working with aligned partners to deliver quality civil projects, and providing
long-term employment opportunities for Indigenous Australians.

He offers expert input from time of tender, exclusively selecting site personnel for all projects and delivering high-class project supervision.  Liam and the Calroc team delivered some of Perth’s most notable, large-scale projects in 2021-22 including:

  • Cranford Avenue PSP: a challenging project with limited access along the Kwinana Freeway which featured a top-down construction tunnel to allow works to continue on the slip road overhead whilst the tunnel was being constructed

  • Mitchell Fwy extension bridges over Lukin Drive: a 105m 3 span bridge over live rail
  • Butler Boulevard: a 52m 2 span bridge which was carried out alongside
  • Stock Road Bridge and culvert package in Bullsbrook: a 4km road upgrade with a single span bridge over Ellenbrook River, giving residents direct access from the Great Northern Highway to Tonkin Highway.
