Software and AI for Australian engineering consultancies

What does an engineering consultancy need its systems to prove?

Beyond hours and invoices, an engineering firm’s systems need to prove who did the engineering, who checked it, and that the person who signed was registered for that work in that state on that day. That proof is what a client, an insurer, a certifier or a court will ask for years after the job closes. Most firms hold it in scattered places: calc packages on a file server, check prints in a cabinet, registration certificates with HR and sign offs in email.

The business side is the familiar part. Projects are costed by discipline, staff book hours against stages, subconsultants invoice the firm, and the firm invoices the client by claim or milestone. The proof side is where generic software stops.

Where do Deltek, WorkflowMAX and Xero stop?

They run projects and money well and hold little about registration, supervision or calculation checks. Deltek describes Vantagepoint as ERP built for architecture, engineering and consulting firms, covering project management, accounting, business development and resource planning, with Ajera for smaller firms. WorkflowMAX by BlueRock and Xero suit smaller practices that want jobs and timesheets close to the accounts.

Need	Covered well by the practice tool	Usually left to spreadsheets or email
Project budgets by stage and discipline	Yes
Timesheets and utilisation	Yes
Subconsultant budgets and invoices	Partly	Approval against scope, retention
Registration by person, area and state		Expiry dates, areas, states
Calculation register and check status		Versions, checker, sign off
Tender capability statements		Reused CVs and project sheets

Keep the practice tool as the financial record. The custom work is a set of registers and workflows beside it, sharing project and staff identifiers so nothing is entered twice.

Three states, three registration regimes

Queensland, Victoria and NSW each regulate professional engineers differently, and a firm working across them needs the rules held per state, per area and per person.

	Queensland	Victoria	NSW
Regulator	Board of Professional Engineers of Queensland	Consumer Affairs Victoria (Professional Engineers Registration Act 2019)	Building Commission NSW (Design and Building Practitioners Act 2020)
Scope	Professional engineering services in or for Queensland	Professional engineering services in or for Victoria in a prescribed area	Professional engineering work on class 2, 3 and 9c buildings, including mixed use
Areas	19 registered areas	5: fire safety, civil, structural, electrical, mechanical	6 classes: civil, electrical, geotechnical, mechanical, structural, fire safety
Main exemptions	Direct supervision by an RPEQ, or work only to a prescriptive standard	Direct supervision by a registered engineer, or work only to a prescriptive standard	Direct supervision by a registered engineer; work excluded under section 31

Two details catch firms out. First, Queensland and Victoria both apply to work done for the state, not only in it, so a Sydney office designing for a Brisbane client is in scope. Second, in NSW a registered professional engineer can’t prepare regulated designs or make design compliance declarations unless also registered as a design practitioner in the relevant class. Building Commission NSW notes that engineers registered in Queensland and Victoria can register in NSW without demonstrating qualifications and experience again.

A registration register should hold, for every engineer: each registration, its areas or classes, its state, its expiry, and the projects where that person signs. It then answers the question a project director needs before issue: is the signer registered for this area in this state today?

Supervision you can evidence

Direct supervision is an exemption from registration, so the firm needs to be able to show it happened. Victorian guidance describes it as the registered engineer having direct contact with the person, directing them to do the work, and overseeing and evaluating it. Queensland and NSW rely on the same concept.

Evidence builds itself when the workflow captures it:

1. A registered engineer assigns the task to a named graduate or technical officer.
2. The calculation or design is recorded against the task with its inputs.
3. The registered engineer reviews it, with comments and a recorded decision.
4. Only the registered engineer can release it for issue.

Nothing here slows the engineering. It replaces the end of project scramble to work out who checked what.

Calculation records that survive a dispute

A calculation record is defensible when it shows the inputs, the method, the version, the checker and the output, and links each to the drawing or report it supports. Most firms have the calcs. What is missing is the link between them and the issued documents.

A calculation register usually tracks:

• Calc reference, project, discipline and element.
• Input sources: brief, survey, geotechnical report, loads, with versions.
• Software and version used, or the spreadsheet file and its hash.
• Designer, checker and date of each check, with check type (independent, peer, self).
• The drawings, specifications or certificates it supports, and their revisions.
• Any superseding calc, so old versions stay visible but clearly replaced.

For NSW regulated buildings, the same register can feed the design compliance declaration process: each regulated design needs its own declaration, must be construction issued and must carry the standard title block before lodgement on the NSW Planning Portal. The NCC edition matters too. The Australian Building Codes Board shows NSW and Queensland adopting NCC 2025 on 1 May 2027 and Victoria on 1 May 2026, so the register should record which edition each design was checked against.

Costing across disciplines and subconsultants

Multi discipline jobs lose margin in the gaps between disciplines and in subconsultant scope, not in the timesheet. Typical gaps include a structural team absorbing coordination time that was priced in civil, or a subconsultant invoicing for a revision the client never approved.

A focused tool can hold each discipline’s budget and each subconsultant’s agreed scope, match subconsultant invoices to approved scope and variations before they’re paid in Xero, and show principals a fortnightly view of fee used against progress by discipline. The data already exists in the practice tool and the accounts; the work is joining it.

Tenders and capability statements from past work

Tender writing is mostly finding the right past projects, CVs and method statements, and then rewriting them for this client. That is a retrieval problem first and a writing problem second. A tender tool indexes past project sheets, CVs and capability statements with tags for sector, client type, value and discipline, finds the closest matches for a new request, and drafts a first version for a person to edit. Our professional services knowledge base page covers the access control side, where some past project content must stay restricted to the original team.

AI over standards, reports and past calcs

AI is useful for finding and drafting, and it needs two firm rules: respect standards licences, and keep engineers in the decision. Standards Australia licenses the reproduction of its content in reports, training materials and tenders through its licensing team. Check your subscription before putting any standard into an index; many firms index their own reports and calcs and leave standards out.

The second rule comes from the profession. The Engineers Australia Code of Ethics asks engineers to act on the basis of adequate knowledge and to be prepared to explain their work and reasoning. An AI assistant that finds a similar retaining wall calc from 2019 and shows its source supports that. One that produces a number without a traceable method does not. Good uses include:

• Finding past calcs, reports and details by element, site condition or client.
• Checking that a calc’s stated inputs match the current brief and geotechnical report.
• Drafting report sections and tender responses from approved past content.
• Summarising long client briefs and specifications into issue lists for the engineer.

Typical builds and indicative costs

Most builds here are registers and workflows beside the practice tool, plus a retrieval layer over past work. Expeed’s 2026 survey of Australian costs puts simple internal tools at $15,000 to $40,000 and mid complexity systems at $40,000 to $150,000.

Build	Indicative range (AUD, ex GST)	Main drivers
Tender and capability assembly over past project data	$25k to $60k	Content volume and quality, tagging, approvals
Calc register with supervision and sign off workflow	$30k to $80k	Disciplines, states, links to drawings and declarations
Knowledge base over reports with project level access	$40k to $100k	Document volume, access rules, evaluation effort

These are planning ranges, not quotes, and exclude licences, hosting and model usage. The workflow automation cost guide explains how workflow builds are usually priced, and our architecture practice software page covers the design practice side of NSW declarations.

How AWLabs approaches engineering firms

We would start with one painful register, usually registration and supervision or calc sign off, and connect it to your existing practice tool before touching anything else. Every engagement starts with a Development Consult, then a paid Discovery Audit credited in full against the build, then a fixed price Schedule of Work with three options: The Minimum, The Recommended and The Complete. Senior engineers lead every build, updates arrive every Tuesday and Friday in Sydney business hours, and code and IP are assigned to you as they are paid for. We have not yet delivered for an engineering consultancy. See our workflow automation service for how we build approval flows.
