Design basis

Codes, standards & units for Indonesia

We set the design basis for Indonesia work before the first model is built, so the calculation report and the drawings speak the same language as your approval chain.

Standard	Discipline	How we apply it
AS 4100	Structural steel	Limit-state steel member and connection design
AS/NZS 1170	Loads	Permanent, imposed, wind, snow and earthquake actions
AISC 360	Structural steel	Member, connection and stability design for frames, racks and platforms
ASME B31.3	Process piping	Wall thickness, flexibility and CAESAR II stress acceptance
SS EN 1993	Structural steel	Singapore National Annex adoption of Eurocode 3

Units on Indonesia jobs

metric

Metric throughout — millimetres on drawings, metres for levels and setting out, kilonewtons and megapascals in the calculations.

What lands in your folder

Native Tekla, STAAD.Pro, CAESAR II and PV-Elite files plus PDF, DWG, DXF, NC1/DSTV and IFC.

Drawing conventions your fabricator expects

Sheets & scales: ISO A1 / A3 sheets, 1:100 GAs and 1:10 details
Dimensions: Millimetres, with reduced levels (RL) in metres
Steel grades: AS/NZS 3678 and 3679 Gr.250 / 300 / 350, or ASTM equivalents
Bolting: AS/NZS 1252 8.8/S and 8.8/TF categories called up on every connection
Welding: AS/NZS 1554 weld symbols with SP / GP category stated
Projection: Third-angle projection with site grid and survey datum

How we work with you

A working day with your Indonesia team

Nothing about this is improvised. Indonesia is 1 h 30 m ahead of our engineering desk (UTC+05:30), so we run a fixed daily rhythm around your working hours in Indonesia.

Sector focus

Industries & project types in Indonesia

Most Indonesia enquiries come from these four sectors — and from the fabricators and EPCs serving them.

Mining

Sector page

Heavy, abrasive-duty structures built far from anywhere — so the drawings have to be right first time.

Conveyor galleries and trestles
Transfer towers and chutes
Silos, bins and hoppers
Crusher and mill building steel

LNG

Sector page

Cryogenic service, heavy modularisation and the documentation trail an LNG EPC expects.

Cryogenic stress and support design
Modularised process racks
Tank appurtenances and access steel
Jetty and loading-arm structures

Marine & Offshore

Sector page

Floating and fixed marine assets where weight control and corrosion allowance are part of the design brief.

FPSO module steelwork
Jetty, dolphin and mooring structures
Marine-grade skid packages
Transport and lift analysis

Commercial

Sector page

Building steelwork where architectural coordination and erection sequence matter as much as the member sizes.

Office and retail steel frames
Atrium and façade support steel
Connection design and bolt lists
Federated BIM model reviews

Commercial & compliance

Contracting, IP and invoicing for Indonesia

Engineering is the easy part of an offshore engagement — the contract, the IP and the invoice are what stall it. Here is how we set those up for Indonesia clients.

Fixed-price package

Quote in 24 h · 2–4 milestones

Best for: A defined scope — one building, one skid, one vessel

Lump sum against an agreed drawing and tonnage list. Milestone invoicing, and change orders only for scope you approve in writing.

Rate-based delivery

Weekly reporting · monthly invoice

Best for: Scope that is still moving

Per-drawing, per-tonne or per-hour rates fixed up front, with a weekly burn and progress report so the invoice never surprises you.

Dedicated engineers (ODC)

Monthly per seat · 1-month notice

Best for: A continuous workload across many projects

Named engineers reserved for you each month, working in your folder structure, templates and drawing standards under your team lead.

The paperwork, up front

Working with SES from Indonesia

Invoicing currency: USD by default — other currencies on request
Payment terms: Milestone or monthly invoicing, net 30 days from invoice
Contract vehicle: NDA, then a master services agreement with a priced scope schedule per package
IP & ownership: Models, drawings, calculations and native files transfer to you on final payment
Cross-border paperwork: Tax-residency and invoice documentation supplied for Indonesia finance and treaty relief
Insurance: Professional indemnity cover; certificate issued with the proposal on request

Local practice: Documentation is built for AS/NZS fabrication practice and for principal-contractor ITP, hold-point and witness-point regimes.

Confidentiality, IP & data security

Mutual NDA signed before drawings are exchanged — usually inside one working day.
All models, drawings, calculations and native files become your property on final payment.
Project data lives in access-controlled folders; only the named team on your job can open them.
No sub-contracting of your scope to a third party without your written consent.
Every deliverable is produced on genuine licensed software, so your submission chain stays clean.
Transfers over your portal, SharePoint, or our encrypted link — whichever your IT policy allows.
