Andrew Doig

PROJECT DIRECTOR

Andrew was born and raised in rural Western Australia and remains a country lad at heart—a blend of passion, commitment, experience, and a sense of fun. He brings a sound, practical approach to solving design problems, grounded in real-world understanding and hands-on experience.

Driven by a strong belief that thoughtful engineering design can enhance and add significant value to any project, Andrew founded ATA Engineering in 2003. His vision was to create a consultancy that is both passionate and responsive to the unique needs of every project.

Andrew oversees all projects at ATA, ensuring they are designed to stand the test of time—supporting end users and enabling them to reach their full potential. He believes engineering plays a vital role in the design process, unlocking creativity and fostering meaningful collaboration across disciplines.

Peter Doig

SENIOR PROJECT DESIGNER

With over 25 years of experience designing smart building solutions (and the occasional killer prosciutto), Peter brings a practical, hands-on approach to engineering challenges. His roots lie in senior design, project management and building services, but his real strength is lateral thinking—especially when it comes to diagnostics. Whether it’s preparing contracts, managing projects, conducting building audits, or compiling detailed engineering reports, Peter is serious about delivering clear, effective outcomes. Outside of work, you’ll find Peter fishing, watching football, or perfecting his craft in dry-aged steaks and homemade pancetta—because precision matters in both engineering and charcuterie.

Stacey Kench

ADMINISTRATION

The team’s newest friendly face, Stacey, brings two years of industry experience and over two decades of customer service, sales, and people development know-how. A natural communicator with a knack for solving problems, smoothing out the bumps, and keeping things moving.

Balancing deadlines, shifting priorities, and the occasional surprise with calm and a can-do attitude. Stacey is organised, deadline-driven, and always ready to lend a hand, especially when it involves colour-coded spreadsheets or a productive planning session. She is responsible for drafting fee proposals, preparing detailed specifications, producing ‘As Constructed’ drawings, and setting up comprehensive service drawings.

When she’s not fuelling the infrastructure of daily operations – mostly through a steady stream of coffee and those colour-coded spreadsheets, you’ll likely find Stacey in her kitchen trying out a new recipe, curled up with a good book, or deep into the latest true crime podcast — purely for the storytelling, of course.
