For anyone engaging a structural engineer for the first time — particularly owner-builders managing a project without a builder’s existing engineering relationships — the process can feel opaque. What actually happens between the initial enquiry and a set of stamped, permit-ready drawings? Here’s a realistic breakdown of the process EMS Engineering Consultancy follows on a typical Melbourne project.

Step 1: Initial Enquiry and Scoping

The process starts with understanding the project — what’s being built or modified, at what stage the design currently sits, and what documentation is needed (a report, computations, or full structural design drawings). This scoping stage determines the fee and timeframe, and is also where any obvious red flags — site constraints, heritage overlays, unusual soil conditions — are identified early.

Step 2: Site Assessment

For most projects, a site visit follows — inspecting existing structure where relevant, confirming site conditions, and gathering the information needed to inform design. For straightforward inspections or reports, this may be the primary component of the engagement. For design work, it feeds into the next stage.

Step 3: Structural Analysis and Design

This is the core engineering work — determining load paths, sizing structural elements (beams, footings, retaining structures, or whatever the project requires), and working through the calculations that support the final design. For projects involving other consultants — architects, civil engineers, building surveyors — this stage often involves back-and-forth coordination to ensure the structural design works within the broader project constraints.

Step 4: Documentation

Once the design is finalised, it’s translated into the structural drawings and computations required for a building permit application. This documentation needs to meet the specific requirements of the relevant building surveyor, and typically includes drawings, computations, and a cover letter or report summarising the scope of work.

Step 5: Permit Submission Support

Structural documentation is submitted as part of the broader building permit application, alongside architectural drawings and any other required reports. Engineers are often called on to respond to queries from the building surveyor during this stage — clarifying details or providing additional information if requested — before the permit is issued.

Step 6: Construction-Stage Support (Where Required)

For some projects, particularly larger or more complex ones, the structural engineer’s involvement continues into construction — responding to site queries, reviewing any proposed variations, or in some cases conducting inspections at key construction stages to confirm the structure has been built in accordance with the design.

What Determines Timeframe

Turnaround varies significantly based on project complexity — a straightforward inspection report moves faster than full structural design documentation for a multi-unit development. Site access, the completeness of information provided at scoping stage, and how quickly queries are resolved with other consultants all affect the realistic timeline, which is why an accurate scoping conversation at the outset is genuinely useful rather than a formality.

Getting the Most Out of the Process

For builders and owner-builders, the projects that move most smoothly tend to be the ones where the structural engineer is engaged early, with clear information provided upfront, and where queries during the design and permit stages are responded to promptly. Treating structural engineering as a late-stage box to tick, rather than an early planning partner, is one of the more common (and avoidable) sources of project delay.
