Pricing, process, timelines, deliverables, standards and engagement terms, answered the way clients actually ask them. Read what you need, then send a brief.
Senger Engineering is a mechanical engineering consultancy based in Perth, Western Australia. The studio delivers first-principles mechanical design, FEA verification, fabrication and shop drawings, product development and 3D visualisation for industrial, mining and architectural clients across Western Australia.
Every engagement is quoted on a fixed-scope basis after a free 30-minute scoping call. Typical ranges: small design and drawing packages from a few thousand dollars; mid-size FEA verifications and fabrication packages in the low five figures; multi-stage product development engagements scoped in phases. A written proposal with deliverables, timeline and fee is sent within 48 hours of the scoping call.
Five stages:
Typical brief response is within 48 hours. Indicative turnaround by scope:
Deliverables depend on scope but typically include 3D models (SOLIDWORKS native plus neutral formats), manufacturing drawings to AS 1100 with weld schedules, bolt callouts and BOMs, engineering calculations referenced to the applicable Australian Standards, FEA reports with assumptions and results, DFM/DFA reviews, and a signed design report or memorandum where the engagement requires it.
Principal codes routinely applied:
Additional codes consulted as required, including NCC/BCA, AS 1428 (access and mobility), AS 1418 (cranes) and AS 4024 (machinery safety).
Yes. FEA and structural simulation are part of the core capability, used to verify first-principles hand calculations, investigate failure modes, optimise mass, and check serviceability and ultimate limit states. Deliverable is a written FEA report with assumptions, boundary conditions, mesh quality, results and conclusions.
Yes. I'm Perth-based but work remotely across WA and Australia-wide all the time. Files go through secure project folders, design reviews run over video, and I come to site when the job needs it.
Three main sectors:
Yes, a mutual NDA is available on request before any commercially sensitive material is shared. Many engagements proceed without one; an NDA is offered as standard for product development and proprietary equipment work.
Structural engineers focus on buildings, framing and load paths governed by codes such as AS 4100 and AS/NZS 1170. Mechanical engineers focus on equipment, machinery and components, moving parts, fasteners, welds, fatigue, manufacturability and integration with structure. Industrial scopes (plant, mining equipment, modular systems) frequently sit between the two; Senger Engineering operates in that overlap, applying both mechanical (AS 3990) and structural (AS 4100) codes as the scope requires.
Yes. Send me a 3D model, a PDF or a hand sketch, and I'll turn it into fully detailed manufacturing drawings to AS 1100: weld schedules, bolt callouts, BOMs and finish notes, ready to hand straight to the fabricator.
Design reports and calculations are issued under the studio's professional indemnity. Where a project requires statutory certification (RPEQ, CPEng, building surveyor sign-off, third-party verification), the scope is confirmed up front and the appropriate certifier is engaged or coordinated as part of the package.
Primary CAD is SOLIDWORKS, with FEA run in SOLIDWORKS Simulation and complementary tools as required. Drawings are issued in PDF and native formats; renders are produced from native engineering models with photoreal output.
Email info@senger.com.au or call +61 0413 886 800. Send whatever you have, a brief, a sketch on a napkin, a full specification, or a folder of drawings. A free 30-minute scoping call is booked, followed by a written fixed-scope proposal within 48 hours.
I quote every job on a fixed-scope basis so you know the full cost before I start. I carry the risk of getting the estimate wrong, not you. Hourly billing rewards dragging the work out; fixed-scope ties payment to what actually gets delivered: drawings issued, calculations signed, reports done. If the scope changes mid-project, I write up a variation and get it approved before carrying on.
Every job includes two rounds of revisions to deal with your feedback on what I've issued. Anything beyond that, or changes driven by new requirements outside the original scope, I quote as a written variation. If the mistake is mine, I fix it at no charge.
The studio is Australian-registered and routinely engages Australia-wide on remote projects. Overseas engagements are accepted where the deliverable is design, drawings, FEA or product development that does not require Australian statutory certification on site. Standards applied default to Australian (AS/NZS) unless the client specifies ISO, EN, ASME or another framework up front.
On client-commissioned work, the client owns the final design IP on full payment. Senger Engineering retains the right to use the work in its portfolio and case studies unless an NDA or non-disclosure clause restricts this, agreed in writing before work begins. Background IP (the studio's methods, templates, libraries) remains the studio's.
Yes. I regularly pick up part-finished designs, drawings or analyses from other consultants. The first thing I give you is a short handover review: what's sound, what needs rework, and what the remaining scope and fee look like, in writing, before the main work starts.
Enough to understand the scope. That can be a one-paragraph brief plus a sketch, a specification document, or a folder of existing drawings, whichever the client has. The free 30-minute scoping call fills the gaps. A written fixed-scope proposal follows within 48 hours of that call.
Yes. Senger Engineering carries professional indemnity insurance appropriate to mechanical engineering consultancy work in Australia. A certificate of currency is provided on request as part of contractor onboarding for tier-1 clients and mining operators.
Your files sit in access-controlled project folders, not shared cloud drives. I never use your designs, drawings or commercial information in marketing without written consent. And I'll sign a mutual NDA on request before any sensitive material changes hands, which is standard for product development and proprietary equipment.
