What Does an Industrial Structural Engineer Do? | PBE

In short

An industrial structural engineer designs and assesses the load bearing structure of factories, warehouses, sheds and other industrial buildings, covering slabs, hardstands, portal frames, mezzanines and racking support, while making sure the design meets Australian Standards and Victorian building permit requirements.

Industrial buildings carry different demands to a house or an office fit out. Heavy machinery, forklift traffic, racking loads and wide clear spans all place specific requirements on the structure, and an industrial structural engineer is the person who works out how the building will carry them safely. This page sets out what the role covers, how it differs from residential structural engineering, and what to expect from the design process.

The role of an industrial structural engineer

An industrial structural engineer is responsible for the structural design and assessment of buildings used for manufacturing, warehousing, distribution and processing. The role involves calculating the loads the structure will carry (dead loads, live loads, wind and seismic actions, plus operational loads from equipment and racking), then sizing the structural elements, footings, slabs, frames and connections, to carry those loads safely within the relevant Australian Standards.

Key Point: Industrial structural engineering is not limited to the building shell. It also covers hardstands, internal slabs, mezzanine floors and the support structure for racking and plant, all of which need to be assessed against the specific loads the site will carry.

The engineer also reviews how the structure interacts with the rest of the building. Column layouts, portal frame spacing and bracing all need to work with the operational floor plan, so the engineer typically coordinates with the architect, builder and services consultants throughout the design.

How an industrial structural engineer differs from a residential structural engineer

The term structural engineer covers a broad range of work, and residential and industrial projects call for different technical focus.

Residential structural engineer	Industrial structural engineer
Typical loads: occupants, furniture, standard wind and snow actions	Typical loads: forklifts, racking, cranes, process equipment, vibration
Common elements: timber and steel framing, footings, load bearing walls	Common elements: portal frames, hardstands, heavy duty slabs, mezzanines
Typical spans: modest room widths	Typical spans: wide clear spans for equipment and vehicle movement
Common triggers: renovations, extensions, wall removal	Common triggers: new facilities, fit outs, racking installs, plant upgrades

A building surveyor checks that a completed design meets the building code and issues the permit. The structural engineer is the one who produces the structural design and certification that the surveyor relies on, so the two roles are related but distinct.

What an industrial structural engineer designs

On a typical industrial project, the structural scope generally includes:

Portal frames and steel or precast concrete structure for the building shell
Footings and foundations sized for the site's soil conditions
Ground floor slabs designed for point loads from racking and rolling loads from forklifts
External hardstands for truck movement, container storage and loading docks
Mezzanine floors for additional storage or office space within the shed
Bracing and connections to resist wind loads across large roof and wall areas

The industrial structural design process

Site assessment

The engineer reviews the site, existing structure (if any) and geotechnical information to understand ground conditions and constraints.

Load analysis

Operational loads are established with the client, covering racking, equipment, vehicle movement and any process specific demands.

Structural design

Frames, slabs, footings and connections are designed and modelled to carry the assessed loads within the relevant Australian Standards.

Documentation

Structural drawings, specifications and computations are issued for permit and construction, coordinated with the architect and other consultants.

Timeframes vary with project scale and complexity. A straightforward warehouse fit out can be documented in a matter of weeks, while a new industrial facility with multiple structural systems takes longer, particularly where geotechnical investigation or council coordination is required.

Codes, permits and compliance for industrial structures

Industrial structures in Victoria are designed to the relevant Australian Standards for structural design and loading, and the completed design forms part of the building permit application lodged with a building surveyor. Depending on the site and use, planning approval from the local council may also be required before a building permit can be issued, particularly for new industrial developments or a change of use. An experienced Melbourne structural engineering consultant can advise early on which approvals apply to a given site.

When to bring in an industrial structural engineer

An industrial structural engineer should be engaged at the concept stage of a new facility, before layouts and column grids are locked in, so that structural constraints can inform the design rather than be worked around later. Engagement is also appropriate for an existing building when adding racking, installing a mezzanine, upgrading plant, or where a structural engineer inspection has identified a need to assess the existing structure against new loads.

Frequently asked questions

What does an industrial structural engineer do?
An industrial structural engineer designs and assesses the structure of industrial buildings, including frames, slabs, footings, hardstands and mezzanines, so the building safely carries its operational loads and meets the relevant Australian Standards.

Do I need a structural engineer for a factory?
Yes. A structural engineer's design and certification is required to obtain a building permit for a new factory, and is also needed for significant alterations such as a mezzanine addition, racking installation or structural upgrade to an existing facility.

How are industrial building slabs and hardstands designed?
Slabs and hardstands are designed for the specific loads they will carry, including point loads from racking legs, rolling loads from forklifts and heavy vehicles, and the subgrade conditions revealed by a geotechnical assessment.

What is involved in industrial shed design?
Industrial shed design covers the portal frame or structural steel system, footings, bracing, roof and wall cladding support, and coordination with the internal floor plan, racking layout and any mezzanine or office areas.

How long does industrial structural design take?
Programme depends on the scale and complexity of the project. A straightforward fit out or racking assessment can be turned around quickly, while a new facility with multiple structural systems and council or planning coordination takes longer.
