Short answer: an outsourced structural package is production capacity, not a professional of record. You get the analysis model, the calculation package, the drawings, the detailing and the structural quantities — in native, editable formats — and your locally licensed engineer reviews, approves and seals. Firms that get burned by outsourcing almost never got burned by the engineering. They got burned by the brief.
1. The design standard and its edition · 2. Who checks what, in writing · 3. The drawing revision quantities come off · 4. Your CAD standards and title block, sent not assumed
The firms this works for are not trying to shave an hourly rate. They are small technical teams that already have clients and already understand engineering, and they have hit a production ceiling that a full-time hire cannot fix economically — because the workload that exceeds the bench is lumpy. Three overlapping projects in March, a quiet May. Hiring for the March peak means carrying it through May.
Framed that way, the comparison is not "offshore hour versus local hour." It is "packages delivered against dates" versus "work turned away, or dates missed." That is the honest case for it, and it is also why picking a partner on price alone tends to go badly: the cheapest hour is usually the one with no independent check behind it, and a package that needs re-checking has cost you more than it saved.
The format question matters more than it sounds. A deliverable you cannot open, edit or interrogate is not reviewable, and if your engineer cannot review it they cannot responsibly seal it.
| Deliverable | What it contains | Format it should arrive in |
|---|---|---|
| Structural analysis | Load calculations, gravity, wind and seismic analysis to your specified standard | Native STAAD.Pro or ETABS model file, plus the calculation package as PDF |
| Design development | Beam, column, slab and foundation design; steel member and connection design | Calculation package with the design checks shown, not just outputs |
| CAD documentation | Framing plans, foundation plans, sections, details, revisions | Layered DWG plus print-ready PDF sheets — on your title block |
| Rebar & steel detailing | Structural schedules and detailing matched to how the frame gets built | DWG and PDF, with schedules cross-referenced to the drawings |
| Structural BOM / BOQ | Bill of materials, bill of quantities and take-off for the structural scope | Structured Excel, formula-live and itemised — not a flattened export |
The BOM and BOQ deserve a specific note: they should be produced from the same model and drawing set as the documentation and reconciled against it before delivery. Quantities generated in isolation from the drawings are the single most reliable source of downstream argument, and reconciliation is a step you should ask about explicitly. The general principles of how those documents are built are in our BOQ, BOM, POW and DUPA guide.
Where the Line Is — Stated Plainly
AEDO provides structural analysis, design development and documentation as engineering production support. Depending on jurisdiction, final review, approval and sealing may require a locally licensed professional. Our work is prepared for review and approval by your firm's locally licensed structural engineer where required — AEDO does not represent itself as the engineer of record in a jurisdiction where it is not licensed to act as one. Any partner unwilling to say that sentence out loud is a partner whose professional-indemnity position you should ask about before you send them a project.
Scores how ready your brief actually is, names the specific gaps that cause rework, lists the deliverables and formats you should be receiving, and gives an indicative production window. Most outsourcing failures are decided here, before any engineering happens.
This is worth its own section because it is the most expensive and most avoidable failure in the whole arrangement.
"Design to ASCE 7" is not a brief. Neither is "AS/NZS 1170" or "Eurocode." Seismic and wind provisions move materially between editions, and the national annex or amendment is not a formality — for Eurocodes it sets partial factors, and for the AS/NZS suite the Australian and New Zealand annexes are genuinely different documents rather than regional spellings of the same one. A package produced to the wrong edition is not corrected. It is redone.
A competent offshore partner will ask for this before quoting. If they do not ask, that tells you something about how the last twenty projects went.
The Timezone Is an Asset Only If the Brief Is Complete
The Philippines runs on GMT+8. For Australian and New Zealand firms that is live overlap through most of the working day — questions get resolved inside one day. For firms in the United States, Canada or the United Kingdom it works as an overnight production cycle: brief at your end of day, and the work advances while your office is dark.
The catch is symmetrical. With a complete brief, the offset buys you a free shift. With an incomplete one, every unanswered question costs a full day rather than a five-minute conversation — and three such questions in a week erase the advantage entirely. This is the practical reason the scoping sheet matters more than the hourly rate.
"We check our work" is not a process. These are the specific ones to ask any offshore partner to describe:
Nobody should hand an unfamiliar team a flagship project. The sensible entry is a bounded piece of work with a real deadline and a known answer — a package your own team could produce, so you can compare rather than hope.
The full set of handover failure modes, and the scoping sheet that prevents them, is in Outsourcing Structural Engineering: What Actually Goes Wrong.
The deliverables, file formats, toolchain, QA steps and the statement of where professional responsibility sits describe AEDO's own offshore engineering service and are consistent with our offshore engineering page. The production window in the calculator is an indicative planning range for scoping conversations — not a quotation, not a commitment, and not derived from a published schedule; actual programmes are agreed per engagement. Pricing is set per engagement and quoted in USD, and is deliberately not published here because scope rather than hours determines it. Review, approval and sealing requirements vary by jurisdiction and rest with your locally licensed professional.
Who signs and seals work produced by an offshore engineering team?
Your locally licensed engineer does. An offshore team provides structural analysis, design development and documentation as engineering production support; depending on the jurisdiction, final review, approval and sealing require a professional licensed in that jurisdiction. A credible offshore partner states this plainly rather than implying it can act as engineer of record where it is not licensed to. Review and approval responsibility should be written into the scope before work starts, not assumed.
What file formats should an outsourced structural package be delivered in?
Native and editable, not flattened. Analysis and design should arrive as the native STAAD.Pro or ETABS model file plus the calculation package as PDF, so your reviewing engineer can interrogate the model rather than take the results on trust. Drawings should be layered DWG plus print-ready PDF sheets, ideally on your own title block. Quantities should be structured Excel workbooks with the formulas live, not a flattened export. If you cannot open and edit what you receive, you have bought a picture of engineering rather than engineering.
Which design standards can an offshore team work to?
The standard is something you specify, not something the offshore team defaults to. AEDO works to the standard nominated in the scope — IBC and ASCE, the NCC and AS/NZS suite, Eurocodes, or the Philippine NSCP. The failure to avoid is naming a code family without naming the edition and the national annex or amendment, because seismic and wind provisions differ substantially between editions and a package produced to the wrong one has to be redone rather than corrected.
What usually goes wrong when structural engineering is outsourced?
Almost always the brief, not the engineering. The recurring failures are a code named without its edition, no written statement of who checks what, quantities taken off a different drawing revision than the one issued, office standards assumed rather than sent, and feedback given verbally on a call with no written record. Every one of those is fixed at scoping, which is why a scoping sheet is worth more than a lower hourly rate.
How does timezone difference affect an offshore engineering engagement?
The Philippines is GMT+8. For Australian and New Zealand firms that means live overlap through most of the working day, so questions get answered inside a single day rather than bouncing overnight. For firms in the United States, Canada or the United Kingdom, the offset works as an overnight production cycle — brief at your end of day and the work advances while your office is closed. That only pays off if the brief was complete, because an incomplete brief converts the offset from an advantage into a full day lost per question.
Is outsourcing structural engineering cheaper than hiring?
It solves a different problem. A full-time hire is the right answer to sustained, predictable workload. Outsourcing is the right answer to a production ceiling that moves — the weeks when the pipeline outpaces the bench and the alternative is turning work away or missing dates. Judged purely on hourly rate the comparison is misleading, because a hire carries recruitment, onboarding, idle time between projects and the cost of being wrong about future workload. Judge it on delivered packages against dates instead.
AEDO Engineering works alongside international engineering and construction firms — structural analysis, design development, documentation, detailing and structural BOM/BOQ — while your firm keeps the client relationship and the local professional sign-off.
