Refineries, Heritage Buildings & Industrial Retrofits Done Right
The Inner West of Sydney is home to some of the city’s most complex refurbishment environments. From legacy refinery and industrial sites through to heritage-listed warehouses, factories, and commercial buildings, these assets were never designed with modern codes, loading requirements, or services in mind.
Yet today, they’re being asked to support:
New plant and equipment
Adaptive re-use and change of occupancy
Heavier floor loads
Updated fire, seismic, and structural standards
Modern services routing in very old structures
This is where many refurbishment projects run into trouble — not because the design is poor, but because the starting information is wrong or incomplete.
The Inner West Problem: Old Buildings, New Standards
Much of the Inner West’s industrial and heritage building stock was constructed:
Under superseded Australian Standards
With unknown material properties
Using construction methods no longer permitted
With undocumented modifications over decades of use
What often looks acceptable visually may be:
Structurally marginal under modern load cases
Locally compromised due to corrosion, settlement, or fatigue
Modified in ways that no longer match original drawings
When these issues are discovered late in the design process, the outcome is almost always the same:
Redesign
Strengthening
Programme delays
Budget escalation
Why Waiting Until “Detailed Design” Is Too Late
A common scenario we see in Inner West refurbishments:
Concept design proceeds based on legacy drawings or assumptions
Floor layouts, equipment, and architectural intent are developed
Engineering review begins
Structural checks identify:
Inadequate floor capacity
Unsupported penetrations
Changed load paths
Degraded or altered members
Design is forced to change — often significantly
At this point, the engineer isn’t blocking creativity — they’re responding to reality.
The issue isn’t engineering input. The issue is when the true condition of the structure becomes visible.
Start With a Scan: Let Designers Create With Confidence
Engineering-grade 3D laser scanning at the very beginning of a refurbishment changes the entire dynamic of a project.
Instead of reacting to unknowns later, the project team starts with:
Verified geometry
True floor levels and deflection
Structural alignment and deformation
Accurate column, beam, and slab positions
Measured deviations from original drawings
This gives architects and designers something powerful:
Freedom to design within known constraints — not guessed ones.
Heritage & Industrial Retrofits: Why Scanning Matters Even More
Heritage Buildings
Heritage structures often prohibit invasive investigation early on. 3D scanning allows:
Non-intrusive verification of geometry
Identification of movement or deformation
Assessment of tolerance drift over time
Planning of sympathetic strengthening solutions
Refineries & Legacy Industrial Sites
Inner West refinery and process facilities bring additional challenges:
Tight access
Live plant interfaces
Safety-critical environments
Brownfield congestion
Scanning provides:
Safe remote measurement
Clash-free retrofit design
Confidence before shutdowns
Reduced rework during construction
When Standards Change, Reality Matters
One of the most common late-stage surprises in refurbishments is floor capacity.
Buildings that performed adequately for decades may no longer comply with:
Current live load requirements
Change-of-use provisions
Equipment point loads
Modern safety factors
Without accurate structural geometry and context, engineers are forced to:
Assume worst-case scenarios
Over-design strengthening
Restrict layouts unnecessarily
Early scanning supports informed engineering judgement, often resulting in:
Targeted strengthening instead of blanket solutions
Retention of original fabric where possible
Reduced material and construction costs
From Point Cloud to Engineering Decisions
At Hamilton By Design, scanning is not a standalone service — it’s an engineering tool.
Our process typically supports:
Structural verification of existing buildings
Floor flatness, level, and deflection assessment
Alignment checks of columns and frames
Scan-to-CAD models for design integration
Fit-for-purpose information for refurbishment decisions
This is especially critical in Inner West projects, where:
Every millimetre matters
Access is limited
Heritage considerations are real
Late changes are costly
Design With Knowledge, Not Surprises
Refurbishments don’t fail because buildings are old. They fail because assumptions survive too long.
By starting with an engineering-led scan:
Designers get space to create
Engineers get data they can trust
Asset owners avoid late-stage shocks
Projects move forward with confidence
If you’re planning a refinery upgrade, heritage refurbishment, or adaptive re-use project in Inner West Sydney, the smartest decision you can make is to scan first — before concept becomes constraint.

Engineering-grade 3D scanning at the start gives your project clarity, confidence, and creative freedom — not limitations.
The Australian Standard AS 3990, “Mechanical Equipment – Steelwork,” is critical for ensuring the design and construction of safe, reliable, and durable steel structures in mechanical systems. It establishes guidelines for materials, construction practices, and stress analysis to meet the demanding requirements of industrial and mechanical applications. Failing to consult AS 3990 can lead to significant challenges for companies and individuals involved in engineering projects. Additionally, an engineering company like Hamilton By Design, with extensive experience in mechanical design and steelwork, can address these challenges effectively by leveraging its expertise and adherence to industry standards.
Our clients:
1. Structural Failures
One of the most severe consequences of not consulting AS 3990 is the risk of structural failures.
