Engineering Lessons from Recent Media: Foundations & Process First

A recent Tasmanian news story reported on a homeowner receiving a substantial payout after major renovations led to cracking in their house. The coverage in The Mercury described how the problems were linked to inadequate consideration of existing footings and ground conditions during the design of a second-storey extension:

Legal industry commentators also discussed the same matter as a reminder of professional responsibilities when working on existing buildings:

Rather than revisiting who was right or wrong, the reporting offers a constructive opportunity to reflect on how everyday engineering processes can be improved—especially on renovation and brownfield projects where information is incomplete.

1. Investigation Is Part of Design

The media narrative highlights a simple truth:
when we work with existing structures, the ground and foundations are not background details—they are primary design inputs.

Good practice means:

Treating site verification as a formal stage of the project
Making recommendations for geotechnical or structural checks early
Being clear about what is known and what is assumed

A design based only on drawings is never as reliable as one based on verified conditions.

2. Make Assumptions Visible

News coverage often shows that problems grow in the grey space between architect, engineer, and builder.

Helpful habits include:

Keeping an assumptions register shared by the whole team
Noting on drawings what has been confirmed on site
Setting clear triggers for further investigation

When assumptions have owners, risks have boundaries.

3. Communication Is a Structural Element

Many reported disputes stem less from technical ability and more from gaps in communication.

Engineers can lead by:

Discussing uncertainties openly at the start
Confirming decisions in writing after meetings
Encouraging contractors to report unexpected conditions

Good communication is often cheaper than remediation.

4. Scope Changes = Risk Changes

Renovations rarely stay the same as the first sketch.
Media accounts of failures frequently involve projects that grew beyond the original intent.

Better process includes:

Re-checking engineering scope whenever the design evolves
Linking approvals to stages of investigation
Pricing verification as a real deliverable, not an afterthought

Clarity of scope is a form of structural strength.

5. Document the Story of the Project

Journalists and lawyers both rely on records to understand what happened.

For engineers, simple steps make a big difference:

Photos tied to inspection notes
Short design basis statements
Emails confirming client instructions
Sketches of as-found conditions

Documentation is not defensive—it is professional memory.

6. Respect the Interface Between Old and New

The media coverage repeatedly points to the moment where new work met an older structure.
That interface is where uncertainty lives.

Practical responses:

Specific checks on existing footings before adding load
Independent review for heritage or unknown construction
Monitoring after completion to confirm behaviour

The junction between old and new deserves the most attention.

7. The Courage to Pause

Perhaps the most human lesson from the reports is that engineers sometimes need to slow a project down.

Saying:

“We need more information before proceeding”

is not obstruction—it is professionalism.

Organisations that support this courage protect clients and engineers alike.

Turning Headlines into Better Practice

The story covered by The Mercury and the subsequent industry commentary do not need to be read as cautionary tales. They can be read as learning opportunities:

Investigate before you calculate
Make assumptions visible
Communicate uncertainty early
Document decisions clearly
Treat existing conditions with respect

These are the foundations of good engineering, long before concrete is poured.

Final Thought

Risk will always exist in renovation and brownfield work.
What we control is the process we wrap around that risk.

When engineers focus on verification, transparency, and collaboration, projects become safer, clients are better served, and the profession grows stronger.

Good engineering is not only about correct numbers—
it is about asking the right questions at the right time.

Australian Standards That Shape Engineering, Scanning & Documentation Projects

Australian Standards play a critical role in how engineering, design, and construction work is delivered — particularly on industrial, mining, power, and brownfield projects where safety, reliability, and compliance matter.

At Hamilton By Design, engineering services, 3D scanning, CAD modelling, and as-built documentation are delivered with a clear understanding of how Australian Standards inform real-world engineering decisions. Rather than treating standards as a checklist, they are applied as part of a practical, engineering-led workflow.

Why Australian Standards matter in real projects

Australian Standards exist to ensure that structures, equipment, and systems are:

Safe to build, operate, and maintain
Fit for their intended purpose
Designed and documented consistently
Defensible if designs are reviewed or audited

On existing sites, outdated drawings and undocumented modifications make standards-based assessment even more important. Accurate data, clear documentation, and sound engineering judgement are essential to applying standards correctly.

Key Australian Standards referenced across our work

The following Australian Standards are commonly referenced across Hamilton By Design projects and content, particularly where engineering, scanning, drafting, and compliance intersect.

AS 1657 – Fixed platforms, walkways, stairways and ladders

This standard governs access systems used for operation and maintenance.

It is frequently applied when:

Assessing existing platforms and walkways
Designing upgrades or retrofits
Verifying clearances, handrails, and access geometry

Engineering-grade as-built information is often required to accurately assess compliance on existing sites.

AS 3990 – Mechanical equipment steelwork

AS 3990 applies to steelwork that supports mechanical equipment.

It is commonly referenced for:

Equipment support frames
Plant steelwork and interfaces
Integration of access systems with equipment

Accurate geometry and documentation are essential when modifying or extending existing steelwork.

AS 4100 – Steel structures

AS 4100 forms the basis for the design and assessment of steel structures.

This standard is applied to:

Structural steel framing
Platforms, walkways, and support structures
Structural upgrades and strengthening works

Structural engineering decisions rely on accurate understanding of existing member sizes, connections, and load paths.

AS 4991 – Lifting devices

AS 4991 covers the design and use of lifting devices.

It is relevant when:

Designing or modifying lifting points
Documenting lifting arrangements
Assessing existing lifting equipment

Clear engineering documentation supports safe lifting operations and ongoing compliance.

AS 4024 – Safety of machinery

AS 4024 relates to machinery safety and risk control.

It is typically referenced where:

Machinery interfaces with structures or access systems
Guarding or safety systems are affected by modifications
Engineering changes may impact operator safety

AS 1100 – Technical drawing (implied through documentation workflows)

AS 1100 governs technical drawing conventions.

While not always referenced explicitly, it underpins:

Engineering drawings
Structural and mechanical drafting
As-built documentation

Clear, standardised drawings are essential for construction, fabrication, and future asset modifications.

National Construction Code (NCC)

The NCC provides a regulatory framework for building compliance.

Engineering and documentation workflows often support:

Existing building upgrades
Compliance verification
Safety-in-design obligations

Accurate as-built documentation helps ensure engineering decisions align with NCC requirements.

The role of 3D scanning and as-built data in standards-based engineering

Australian Standards often require engineers to understand what actually exists on site, not just what is shown on legacy drawings.

Engineering-grade 3D laser scanning and LiDAR are used to:

Capture accurate geometry of existing assets
Identify undocumented modifications
Support standards-based assessment and design
Produce reliable as-built documentation

This is particularly important on brownfield and live sites where assumptions introduce risk.

Applying standards with engineering judgement

Australian Standards do not replace engineering judgement — they rely on it.

Effective application of standards requires:

Accurate site information
Understanding of real operating conditions
Clear documentation of assumptions and limitations
Coordination between engineering, drafting, and construction

This is why standards, scanning, drafting, and engineering must work together as part of a single workflow.

Our clients:

Final thoughts

Australian Standards provide the framework for safe and compliant engineering, but outcomes depend on how they are applied.

By combining engineering expertise with accurate data capture and clear documentation, standards can be applied confidently — reducing risk, improving safety, and delivering better long-term asset performance.

Lessons from a Landmark Case:

The Importance of Robust Structural Design Review

In 2024, SafeWork SA concluded a landmark case involving a spectator-roof collapse during a football club redevelopment project in South Australia. While no life-threatening injuries occurred, the incident highlighted how critical it is for design, review, and certification processes to work together to ensure safety on site.

This was the first successful design-related prosecution under South Australia’s Work Health and Safety Act, sending a clear signal to the engineering and construction sector: design decisions carry legal and safety obligations, not just technical ones.

Infographic titled “Lessons from a Landmark Case,” showing engineers reviewing a design, icons highlighting robust review procedures, proper certification, time-pressure risks, and legal design responsibilities. The lower illustration depicts a structure collapsing after four column failures with two workers falling, emphasising the message “Safety starts at the drawing board

What Happened (Briefly)

During roof sheeting works in late 2021, four of seven supporting columns of a cantilevered spectator roof failed, causing two apprentices to slide down the roof sheets. SafeWork SA’s investigation found that the anchor bolts specified for the column base plates were inadequate and did not meet the requirements of the National Construction Code (NCC).

An independent compliance review also failed to detect this issue, allowing the error to pass unchecked into construction. The result was a collapse that could have had far more severe consequences had the roof been fully loaded or occupied.

Key Learnings for the Industry

This case underscores several important lessons for engineers, designers, project managers, and certifiers:

1. Design Responsibility Is a WHS Duty

Under the WHS Act, designers have a duty to ensure their work is safe not just in its intended use, but during construction. This means bolts, connections, and base plates must be designed for real-world loads — including wind uplift, combined shear and tension, and concrete breakout limits per NCC and relevant Australian Standards.

2. Review Procedures Must Be Robust — and Followed

Having a documented review procedure is not enough if it isn’t rigorously applied. Independent verification and internal peer review are critical to catching design errors before they reach site.

3. Certification Is Not a Rubber Stamp

Independent certifiers play a key role in safeguarding public safety. They must actively verify that designs meet compliance, rather than simply sign off on documentation.

4. Time Pressures Can Compromise Safety

Compressed project timelines were noted as a factor in missed opportunities to catch the error. Project teams must resist the temptation to shortcut review steps when schedules are tight — safety must remain non-negotiable.

5. Documentation & Traceability Protect Everyone

Maintaining calculation records, checklists, and review signoffs creates a clear audit trail. This helps demonstrate due diligence if something goes wrong.

Infographic titled ‘Lessons From a Landmark Case’ displayed on a clipboard. It highlights key learnings from a structural failure case: design compliance, safety standards, bolts failure, and adequate specifications. At the centre is a simple line drawing of a collapsed structure, with arrows pointing to four labelled boxes describing the importance of regulatory compliance, workplace safety standards, anchor bolt failures, and using suitable components to meet project requirements

Why This Matters

The collapse at Angaston Football Club was a relatively small incident with minor injuries — but it could easily have been catastrophic. By learning from cases like this, the industry can improve its processes and prevent future failures.

As professionals, our role is to design for safety, verify rigorously, and document clearly. Doing so protects workers, end-users, and our own organisations.

Legal & Ethical Considerations

This post is intended as a learning resource, not as an allocation of blame. The case referenced is a matter of public record through SafeWork SA and SAET decisions, and all commentary here focuses on general principles of safe design and compliance.

We recommend that other practitioners review their own QA and certification procedures in light of this case to ensure compliance with the National Construction Code and WHS obligations.
