Design basis

Codes, standards & units for San Francisco

We set the design basis for San Francisco 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
AISC 360	Structural steel	Member, connection and stability design for frames, racks and platforms
ASCE 7	Loads	Wind, seismic, snow and load-combination basis for every analysis model
AWS D1.1	Welding	Weld symbols, prequalified joints and inspection callouts on shop drawings
ASME B31.3	Process piping	Wall thickness, flexibility and CAESAR II stress acceptance
ASME Sec VIII	Pressure equipment	Vessel, separator and exchanger design calculations in PV-Elite

Units on San Francisco jobs

imperial or metric

You choose at kick-off: imperial-led sheets for US fabricators, or full metric. We hold one unit system per package and never mix them mid-drawing.

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: ANSI D (22"×34") or ARCH D title blocks, 1/4" = 1'-0" GAs
Dimensions: Feet-and-inches to 1/16", with metric dual-dimensioning on request
Steel grades: ASTM A992, A572 Gr.50, A36 and A500 Gr.B/C
Bolting: ASTM F3125 Gr. A325 / A490 — snug-tight or pretensioned, TC assemblies noted
Welding: AWS D1.1 weld symbols with CWI-ready inspection callouts
Projection: Third-angle projection, north arrow and column grid per the EOR drawings

How we work with you

A working day with your San Francisco team

Contracting, IP and invoicing for San Francisco, United States

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 San Francisco, United States 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 United States

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 United States finance and treaty relief
Insurance: Professional indemnity cover; certificate issued with the proposal on request

Local practice: We work behind your Engineer of Record as detailer and analyst; where a state or provincial PE/P.Eng seal is needed it is arranged with a licensed local engineer, and submittals are formatted for AISC-certified fabricator review cycles.

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.
