Argall Promotions

12 January 2026

At ARGALL, promotions aren’t about titles or tenure — they’re about trust. Trust earned through ownership, clear communication, and stepping up when it matters.

At ARGALL promotions aren’t really about titles or tenure.
They’re about trust.

They reflect what a business values and the behaviors it wants to see more of — especially when things are busy or we are venturing into new horizons.

This year, I’m really pleased to recognize two well-earned promotions:
Roy Casumpang, stepping into an Associate for Digital Delivery role, and
Liam Omar, stepping into a Senior Engineer role

Both have consistently shown ownership, communicate clearly, and think beyond their own tasks to support the wider team. That kind of contribution makes a real difference.

With promotion comes more responsibility, but also more opportunity to shape how we work — not just what we deliver.

I’m genuinely excited about the year ahead. We’ve got strong foundations, calm leadership emerging across the team, people stepping up at every level and more team members joining the team later in January.

Here’s to a year built on trust, clarity, and shared responsibility.

LIAM OMAR, Senior PROJECT engineer

Liam is an accomplished Structural Engineer with diverse experience across a wide range of projects throughout Australia. He holds a Bachelor’s Degree in Civil & Infrastructure Engineering with Honors from RMIT and brings over 6 years of combined undergraduate and postgraduate experience to his profession.

He is highly skilled in structural and civil engineering design, client communication, and providing construction stage services. His expertise extends to managing projects within the structural engineering domain, where he ensures compliance with design standards and delivers high-quality, tailored solutions that meet and exceed client expectations.

With a strong passion for efficiency in design, Liam continually seeks opportunities to optimize project outcomes. His commitment to innovation drives him to explore improvements in all facets of a project, from conceptual planning to final execution. An effective communicator and collaborative team member, he excels in building strong relationships with clients and stakeholders, ensuring seamless project delivery and long-term success.

ANDREW GALL, Director

Argall was founded in 2017 by Andrew Gall, an engineer with a passion for complex design and breaking the mould. His work experience as a senior structural engineer across a variety of project disciplines made him realise there was a real need for a bespoke people and service-oriented structural engineering consultancy that would inspire sustainability practices and innovation often lacking in big companies.

This is over and above his experience in traditional procurement roles, his work with builders in the design and construct field, managing projects in sport, tertiary education, the arts and zoological fields, as well as community, commercial, residential and multi- residential enterprises. With such a wealth of knowledge and understanding of different design methodologies, he has the expertise to challenge the status quo in his new venture.
