Country Values. Commercial Capability.

Construction has been part of our family for three generations.

From our origins in family building and trade contracting, Sustainabylt has evolved into a commercial contractor with the experience, resources and management systems to deliver complex projects across multiple sectors.

Our portfolio includes local government and community infrastructure, education and early learning facilities, commercial and retail developments, structural upgrades, building refurbishments and associated civil works.

We have extensive experience working within occupied and operational environments, where construction must be carefully coordinated around essential services, public access, existing operations and multiple stakeholder groups.

These projects require more than a conventional construction programme. They demand practical construction methodology, clear communication, disciplined site management and the ability to respond decisively when circumstances change.

We bring that experience to every project, regardless of its size or location.

Sustainabylt operates under a Triple ISO Certified Integrated Management System incorporating:

• ISO 9001 – Quality Management
• ISO 14001 – Environmental Management
• ISO 45001 – Occupational Health and Safety Management

Our independently certified management systems were implemented a number of years ago and have been maintained ever since. These systems underpin how we plan, procure, manage and deliver our projects.

Our commercial capability extends across estimating, procurement, contract administration, programme management, cost control, quality assurance, safety, environmental management and project close-out.

As Principal Contractor, Sustainabylt combines directly employed tradespeople with an established network of specialist subcontractors, supported by experienced construction management and structured project controls.

Our subcontractors are selected and managed through formal prequalification, contractual and performance management processes.

Importantly, our leadership remains actively involved in delivery. Clients deal with experienced construction professionals who understand the work, know the site and have the authority to make decisions.

This approach combines the governance and commercial discipline expected of major contractors with the responsiveness and accountability of a privately owned business.

Some of our most successful projects have been delivered in environments where conventional construction approaches are not enough.

Occupied public buildings, operational facilities, staged refurbishments, structural modifications, restricted access and latent site conditions require careful planning and the ability to adapt.

We understand the importance of maintaining business continuity, managing public and worker safety, coordinating specialist trades and keeping clients informed as works progress.

Our experience extends to regional and remote project delivery, where logistics, labour availability, weather conditions and access to specialist resources can have a significant impact on programme and cost.

These challenges are addressed through early planning, practical construction methodology, sound commercial management and direct accountability.

We don’t believe every problem needs a complicated solution. We believe it needs the right solution, properly considered and professionally delivered.

Sustainabylt’s work has been recognised through multiple Master Builders Association and Housing Industry Association awards throughout our history.

These include the Master Builders Association Murray Division Award for Best Commercial Project Under $5 Million, recognising our delivery of the Wodonga Homestead Early Learning Centre.

Our reputation is built on the quality of our completed projects, the relationships we maintain and our willingness to take responsibility throughout construction and beyond practical completion.

We value repeat business, long-term relationships and the confidence clients place in our people.

Managing Director Alex Stravakos represents the third generation of his family’s involvement in the construction industry.

Beginning his career as an apprentice carpenter in the family business, Alex subsequently qualified in roof plumbing and progressed through site supervision, project management and registered-builder responsibilities.

With almost 30 years of construction experience, his background spans commercial building, structural works, refurbishment, civil infrastructure, complex construction environments and regional project delivery.

Alex remains actively involved in construction operations, bringing practical trade knowledge and commercial experience to project planning, technical decisions, contractual matters and on-site challenges.

His approach reflects a simple principle: those responsible for delivering a project should understand the work and remain accountable for the outcome.

Outside the construction industry, Alex and his partner Tamara operate a commercial cow–calf enterprise in the remote Snowy Mountains.

Managing a working agricultural property in remote Australia provides a firsthand understanding of the challenges faced by regional communities and businesses.

Distance, difficult conditions, limited resources and the availability of specialist support all demand preparation, resourcefulness and practical decision-making.

When assistance can be hours or days away, problems cannot always be passed on to someone else. They need to be understood and resolved.

That experience reinforces the same values Alex brings to Sustainabylt: preparation, resilience, personal responsibility and a practical approach to getting the job done.

Alex has also served with the Country Fire Authority for more than two decades and holds the rank of First Lieutenant.

His involvement in brigade leadership and major bushfire operations has developed extensive experience in risk management, operational planning, teamwork and decision-making under pressure.

These experiences, both within and outside construction, continue to influence Sustainabylt’s leadership, culture and approach to project delivery.

We believe successful construction is built on trust, capable people, sound planning and clear communication.

Our clients expect us to understand their requirements, manage risk, make informed decisions and deliver quality outcomes.

We take those responsibilities seriously.

We build relationships, honour commitments and stand behind our work.

Whether delivering a complex commercial refurbishment, a regional community facility or a technically demanding structural project, our commitment remains the same.

Plan thoroughly. Communicate openly. Deliver professionally.

Three generations of builders. Professional systems. Practical leadership. Trusted project delivery.

Behind every Sustainabylt project is a team with a broad mix of construction experience, technical knowledge and practical skills. From project planning and commercial management through to site delivery and compliance, our people share a straightforward approach: do the job properly, work together and stand behind what we deliver.
