Structures and infrastructure

Structural steel and connection design

Foundations are only part of the load path. MEG also designs the structures that sit on them — steel beams, equipment skids and support frames, light poles and their base plates — and the bolted, welded and anchored connections that hold everything together.

What we design

  • Beams and support steel for inverters, power conversion skids and BESS units
  • Equipment skids and support frames, designed to the vendor's loads and tolerances
  • Light poles and camera poles: base plates, anchor bolts and their footings
  • Base plates, hold-downs and anchorage into concrete
  • Bolted and welded connections, including moment connections
  • Steel beams, posts and connections for building work

Connections are where designs succeed or fail

Many structural problems start at a connection: a base plate that's too thin, an anchor too close to a concrete edge, a weld that can't transfer the force. We design connections as carefully as the members they join, and detail them so they can be fabricated and installed without guesswork.

Designed together with the foundation

Because MEG also designs footings and piles, we can design the structure, its connections and its foundation together. Loads, anchorage and tolerances line up, and one engineer is responsible for the whole load path.

What's included

  • Member design for beams, columns, frames and skids
  • Bolted and welded connection design
  • Base plate and anchor design into concrete
  • Design for equipment, operating, wind and earthquake loads
  • Fabrication and installation tolerances
  • Review of fabricators' shop drawings against the design
  • Design certification for the structures and connections we design

What you receive

  • Structural designCalculations for the members and connections.
  • Details for fabricationDrawings or connection details the fabricator can work from.
  • Shop drawing reviewChecking the fabricator's drawings against the design.
  • CertificationDesign certification for the structures and connections, where required.

Scope, fee and programme are confirmed in a written proposal for your project before any engineering starts.

What we need from you

  • Equipment general arrangement drawings, weights and support points
  • Vendor loads and tolerance requirements
  • The layout or arrangement
  • Foundation information, or the go-ahead for us to design the foundations too
  • Fabrication preferences, such as sections, bolting or welding, and galvanising

Don't have everything yet? Send what you have. We'll tell you what's missing and whether it affects the proposal.

How it works

  1. Send the detailsEquipment drawings, loads and the arrangement.
  2. ProposalWe confirm the scope, deliverables and programme.
  3. DesignWe design the members and connections and prepare details for fabrication.
  4. Fabrication and installationWe review shop drawings and answer questions from the fabricator and installer.

Who does what

MEG provides

  • Structural steel member and connection design
  • Shop drawing review
  • Design certification

Not included, or by others

  • Fabrication, supply and installation (by the fabricator and installer)

Where a project needs another specialist, we can recommend one and coordinate with them. We make it clear who is responsible for each part.

Relevant experience

MEG's work includes the light pole foundations at Pier Street, Altona, covering moment calculations, base plate design and connection documentation. See project experience.

Questions

Can you design the support steel for our inverters or BESS units?

Yes. We design beams, skids and support frames to the vendor's loads and tolerances, together with their connections and, if you need them, the foundations.

Can you design just the connections?

Yes. Send us the member sizes and design forces and we'll design and detail the connections.

Do you check fabricators' shop drawings?

Yes. We review shop drawings against the design before fabrication starts, which is the cheapest point to catch a problem.

Which standards do you design to?

The relevant Australian Standards, including AS 4100 for steel structures, AS/NZS 4600 for cold-formed steel, AS 5216 for anchorage into concrete and AS/NZS 1170 for loads.
