Arc Structural

Strong as Steel

Delivering Complex Steel Solutions at Speed—Without Excuse

In structural steel, reputation is forged the same way the work is: through precision, consistency,

and performance under pressure. For ArcStructural, that performance is driven by a straightforward principle that shapes everything from project delivery to supplier selection and internal culture—“deliver without excuse.”

Incorporated in November 2020, Arc Structural is a relatively young name in Victoria’s construction market, but the foundations behind it run much deeper. Founder Andrew Moir grew up around the industry through his father, who has spent roughly 40 years in construction. Before launching Arc Structural, Moir served as Operations Manager for his father’s business, Engineering Directions, overseeing day-to-day delivery and building the client and supplier relationships that continue to support ArcStructural’s work today.

Moir’s leadership style was also shaped outside the industry. After leaving high school, he spent time on the tools with his father before joining the military. When he returned, he transitioned into management roles within construction—bringing with him a focus on accountability, clarity, and team cohesion that remains central to the business’s identity.

Structural and Architectural Steel for Tier-One Delivery

ArcStructural operates as a structural and architectural steel contractor, supporting many of Victoria’s tier-one builders across projects that demand both technical expertise and schedule discipline. The company delivers work across infrastructure, health, aviation, education, and large-scale commercial construction, with a strong emphasis on complex builds where steel interfaces with multiple trades and high-performance outcomes are non-negotiable.

A defining element of ArcStructural’s model is its focus on modular and prefabricated solutions—investigating opportunities to shift as much work off-site as possible to improve safety, control quality, and accelerate on-site construction programs. That approach has become increasingly valuable in today’s environment, where compressed timelines, labor constraints, and design coordination challenges often define the difference between a project that runs smoothly and one that doesn’t.

While the company maintains a diverse portfolio, Moir notes that a significant portion of current demand is being driven by the data center sector, alongside major hospital and commercial works. Compared to high-rise construction—where steel scopes can be intermittent and stretched across multi-year timelines—data center programs are typically intense, fast, and continuous.

Where high-rise steel packages might require a burst of activity at early levels, then months of waiting for the concrete structure to rise before returning for roof works, data center builds often compress the bulk of steel activity into a four- to six-month window, requiring the company to move quickly from design to drawings, fabrication, and installation.

Award-Winning Projects and Precision at Height

ArcStructural’s capability is perhaps best illustrated by the projects that have earned recognition at a national level. The company was awarded two national wins through the Australian Steel Institute, acknowledging excellence in both engineering and clad structures—awards that reflect not only fabrication skill, but the planning and coordination required to execute complex geometry within real-world construction constraints.

One award-winning project involved the sky bridge at 308 Exhibition Street, the Shangri-La building, a structure installed at roughly the 46th-plus floor between two towers. The challenge wasn’t simply building it—it was ensuring it would fit first time, at height, without costly or dangerous rework. That demanded extensive surveying and careful alignment with the as-built conditions, supported by modular fabrication off-site so the installation could be executed efficiently and safely.

The second nationally recognized project was the Melbourne Quarter Tower modular roof structure, a multi-level roof spanning eight floors with complex geometry and an incline that made extensive work at height unsafe. To solve this, Arc Structural modularized major components off-site, reducing exposure and keeping high-risk site work to an absolute minimum. The project also required coordination with other contractors working at Arc Structural’s facility, including cladding and additional elements that integrated with the steel frame—highlighting the collaborative logistics necessary to deliver modern modular solutions.

A Growing Team Built for Full-Service Delivery

ArcStructural is structured to keep a significant portion of delivery in-house, supporting tighter control over schedule, quality, and safety. The business includes office-based estimating, administration, and project management; a warehouse operation responsible for processing, fabrication, and welding; and site installation crews including riggers, welders, and crane operators.

The company is now approaching 100 personnel, a sharp increase from the roughly 40-person scale the operation sat at during the earlier transition from Moir’s previous role into the ArcStructural structure. That growth reflects both expanding market demand and an operating model built for end-to-end accountability—one that can handle the pace and complexity of contemporary construction programs.

Culture, Accountability, and an Open Door

In an industry where delays can quickly turn into blame-shifting, ArcStructural takes a different approach. The company’s internal motto—“deliver without excuse”—is positioned as a response to what Moir sees as a lack of accountability across construction delivery when schedules tighten, and pressure rises.

For ArcStructural, accountability is not punitive; it’s clarifying. People are expected to own their role, control what they can control, and support the broader team when a problem emerges. Moir describes this as an “extreme ownership” mindset—recognizing that while you cannot control every external variable, you can influence outcomes through preparation, communication, and personal responsibility.

That mindset is reinforced by a supportive, cohesive team structure. While roles are clearly defined, the culture emphasizes stepping in when someone is struggling and treating success as a shared objective. Moir also maintains an open-door policy, encouraging team members to raise issues early, speak candidly, and maintain transparency across the organization.

Coming from the military, he places particular emphasis on honor, integrity, and trust—traits he prioritizes highly in hiring and leadership development. In high-stakes projects with tight timelines, those characteristics often matter as much as technical skill.

Supplier Management as a Delivery Strategy

ArcStructural’s emphasis on accountability extends beyond its own teams. In steel, no contractor delivers alone—and Moir is direct about the link between supplier performance and his company’s ability to live up to its own promise.

“If our motto is deliver without excuse, we can only deliver as well as the people supplying stuff to us,” he explains.

The company prioritizes suppliers and subcontractors with proven track records—partners who meet commitments, deliver on time, and treat their word as binding. In an environment where design can lag behind program expectations and multiple trades must interface seamlessly, any slip in materials, transport, shop detailing, or engineering can cascade into downstream delays.

As such, ArcStructural places strong value on alignment with key third-party providers, including temporary works engineering for erection methodology, bracing, and structural propping, as well as shop detailing partners whose ability to work proactively—rather than continuously generating avoidable RFIs—can materially impact speed to site.

For ArcStructural, supplier relationships are not a procurement function; they are a core operational strategy.

Industry Trends: Robotics, Skills, and the Next Generation

Looking ahead, Moir sees technology reshaping structural steel and manufacturing at every level. Robotics and advanced processing equipment are already present, but the pace of advancement in software, automation, and integrated manufacturing systems is accelerating rapidly.

He points to global examples of highly automated manufacturing facilities—where speed, precision, and scale are redefining what efficient production looks like—and believes Australian manufacturers will need to continue investing in both equipment and people to remain competitive.

At the same time, he is clear that complex steel structures still rely heavily on experienced tradespeople. Automation can support repetitive processes, but projects involving complex geometry, modular interfaces, and tight tolerance installation continue to demand competence, judgment, and craft.

That creates a second major priority for the sector: attracting younger people into manufacturing and fabrication careers, and equipping them with the skills required to operate increasingly advanced systems.

Moir believes the solution is not solely on-the-job learning. With technology advancing so quickly, he sees strong value in deeper collaboration between education providers and industry—creating training environments that expose students to advanced robotics, multiple equipment platforms, and modern processing systems before they enter the workforce.

Growth Ambitions: Capacity, AI, and Leadership Development

ArcStructural’s growth plan is ambitious but grounded in operational reality. Over the next five years, Moir’s key aspiration is to scale local manufacturing capacity through expansion into a larger facility—potentially through land acquisition and a purpose-built site designed around the company’s specific needs.

At the same time, Arc Structural is actively investing in technology adoption—not only in fabrication and processing equipment, but in the office and administrative environment where efficiency gains can free teams to focus on delivery.

The company has recently joined the Wyndham AI program, partnering with Wyndham City Council and RMIT to explore practical AI implementation. The initial focus is on reducing administrative burden, with the longer-term aim of identifying broader AI opportunities across project management, planning, and internal systems.

For Moir, the objective is clear: stay ahead of the curve, find real efficiency gains, and build an organization that can scale without losing the accountability, quality, and team cohesion that made growth possible in the first place.

A Team Built to Deliver—Collaboratively and Without Excuse

As ArcStructural continues to take on large, complex projects with accelerated timelines, Moir believes the most important differentiator is not steel alone—it is mindset.

Delivering consistently at a tier-one level requires collaboration across the business, proactive communication with clients, and a leadership approach that prevents overload and supports people as the company scales. ArcStructural intends to grow, but to grow in a way that lifts capability across the team and creates opportunity internally—developing the next generation rather than constantly relying on external hires.

Because complex structures are built by people first. And ArcStructural’s promise to clients—and to itself—remains simple:

Deliver without excuse.
