Mechanical Engineering Consultancy · Perth

Engineering that survives the site walk.

We design mechanical and structural steelwork, check it properly by hand or FEA, and hand over drawings the workshop can build from straight away. We also design kitchen exhaust, ventilation and air conditioning for fit-outs and plants. Based in Perth, working across WA for industrial, mining and architectural clients. You deal with the engineer doing the work, registered on the National Engineering Register (NER), not a sales desk.

01Engineering

Engineering, documentation and visuals, from one studio.

Services that carry a job from the first sketch to the fabricator: mechanical and structural design, ventilation for kitchens and plants, and tensile membrane structures form-found, analysed and patterned in-house.

02Engineering Capability

What we bring to every job.

A short list, on purpose. These are the things we do a lot of and do well, not a padded menu.

SOLIDWORKS & 3D modelling
02
FEA & structural simulation
03
Manufacturing drawings
04
Fabrication detailing
05
DFM / DFA
06
Modular & transportable systems
07
Product development & iteration
08
Engineering calculations
09

10
Engineering documentation
03Standards & Compliance

Designed and documented to code.

Every job is designed and checked against the Australian Standards that apply to it. The main codes we work to are below.

AS 4100
Steel structures
AS 3990
Mechanical equipment steelwork
AS 4600
Cold-formed steel
AS/NZS 1170
Structural design actions
AS/NZS 1554
Steel welding
AS/NZS 5131
Fabrication compliance
AS 1657
Platforms & walkways
AS 1100
Technical drawing
AS 1668.2
Mechanical ventilation
AS/NZS 5601.1
Gas installations

Additional standards consulted as required, including NCC / BCA, AS 1428 access & mobility, AS 1418 cranes, AS 4024 machinery safety, and project-specific client specifications.

04Recent work

The model has to argue with the hand calculation.

A recent WA job: rating the arms on an existing cantilever rack. The hand calculation said one thing, the finite element model said another, and the gap between them was the whole answer.

Finite element model of a steel angle arm under load, coloured by displacement, showing the toe of the bearing leg dropping as the open section twists

Angle arms twist before they bend

Displacement on a loaded angle arm. An open section has almost no torsional stiffness, so the load sitting off the shear centre rotates the arm and drops the toe. Size the vertical leg alone and the rating comes out optimistic.

Finite element model of an angle arm welded to a steel upright flange, coloured by von Mises stress, with the fillet welds modelled as separate bodies

Welds modelled, not assumed

Von Mises stress at the arm to upright connection, with the fillet welds built as separate bodies. The moment and the twist both land here, so this is where the rating is won or lost, not in the middle of the arm.
