How we work with you
A working day with your San Antonio team
Nothing about this is improvised. San Antonio is 11 h 30 m behind our engineering desk (UTC+05:30), so we run a fixed daily rhythm around your working hours in San Antonio.
Clock positions use standard time for San Antonio; daylight saving shifts the band by one hour for part of the year.
1 h 30 m
Our extended shift covers 09:00–10:30, San Antonio time
Next morning
Queued at hand-off and answered before your next morning

Commercial & compliance
Contracting, IP and invoicing for San Antonio, 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 Antonio, United States clients.
Fixed-price package
Quote in 24 h · 2–4 milestonesBest 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 invoiceBest 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 noticeBest 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.
