Design basis

Codes, standards & units for Kolkata

We set the design basis for Kolkata 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
IS 800	Structural steel	Limit-state design of building and industrial steelwork
IS 875	Loads	Dead, imposed, wind and snow load derivation
IS 1893	Seismic	Zone factors, response spectra and ductile detailing requirements
IS 2062	Materials	Plate and section grades E250 / E350 and their weldability
IS 2825	Pressure equipment	Unfired pressure vessel code, used alongside ASME Sec VIII

How we work with you

A working day with your Kolkata team

Nothing about this is improvised. Kolkata runs on the same clock as our engineering desk, so we run a fixed daily rhythm around your working hours in Kolkata.

Commercial & compliance

Contracting, IP and invoicing for Kolkata, India

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 Kolkata, India 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 India

Invoicing currency: INR or USD, fixed at contract stage
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 India finance and treaty relief
Insurance: Professional indemnity cover; certificate issued with the proposal on request

Local practice: GST-compliant invoicing, direct coordination with your fabricator and consultant, and documentation formatted for third-party inspection agencies.

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.
