ACS Engineers (Aust) Pty Ltd

ACS Engineers is a Civil and Environmental Engineering and Project Management company based in both Beaudesert and Boonah. We have extensive experience, servicing clients from a variety of sectors.

Born and raised in the Scenic Rim, both Susan Shay and Angela Harlen have strong ties to the region and its community. By seizing an opportunity and combining both their passions for business and engineering, the pair are now servicing the Scenic Rim through their company ACS Engineers.
Based in Beaudesert, ACS Engineers is a Civil and Environmental Engineering and Project Management company, assisting a range of clients from homeowners and councils to agricultural and industrial developers.
With Angela’s background in business and Susan’s 17 years experience in the civil and environmental consultancy industry and as a Registered Professional Engineer Queensland (RPEQ), the pair established the company back in June 2016.
Four years on, the company now employs an additional six staff and works closely with the community on a number of civil, environmental and management projects.
“Taking on the risk of purchasing an engineering business and not being an Engineer was very daunting at the start,” Angela said.
“But I love the people that I work with and enjoy observing them solving problems of the ever-changing world we live in. I never realised how interesting flushing a toilet or rubbish dumps could be.”
With respective families of their own, both Susan and Angela have had to find the balance between work and family life and are thankful they can wholeheartedly trust and rely upon one another.
