Structural Drafting Group

## Structural Drafting Group

Structural Drafting Group (SDG) is an engineering outsourcing firm based in India, operating under an US-facing brand at structural-drafting.com. The company specializes in structural drafting, steel detailing, BIM modeling, and multi-discipline engineering documentation for fabricators, contractors, EPC firms, and engineering consultants worldwide.

This is a technically focused outsourcing shop, not a general BPO. The work they do sits at the intersection of engineering drafting and construction documentation -- a niche that requires domain expertise, not just labor arbitrage. If you are a steel fabricator or structural engineering firm looking to offload drawing production, SDG positions itself as a delivery partner for that specific workflow.

### What SDG Actually Does

The service offering covers several distinct disciplines.

**Steel Detailing** is the core. SDG produces structural steel detailing deliverables including shop drawings, erection drawings, anchor bolt plans, connection sketches, bills of material, and 3D model-driven project documentation. They also handle miscellaneous steel -- stairs, handrails, ladders, platforms, canopies, and other metal components across commercial, industrial, and residential projects. Connection design is a separate service line: beam, column, bracing, splice, moment, shear, and stair/railing connection drawings and calculations.

**Mechanical and Rebar Services** sit alongside the steel work. This includes mechanical drafting and design, piping design services, rebar detailing, rebar designing, and rebar estimation. For projects that span both structural and mechanical scopes, SDG claims to handle both under the same workflow.

**MEP and Electrical** is a third practice area. Services listed include MEP design, electrical drafting, LV/HV device drawings, electrical site plans, one-line diagrams, and power and lighting plans. This is a broader scope than pure structural work, and buyers should probe how these are staffed -- whether MEP work sits with the same team or a separate group.

**BIM Services** round out the offering. SDG offers BIM modeling, Scan to BIM, CAD/PDF to BIM conversion, architectural BIM, and structural BIM. The framing is model-based review before construction, which is the right way to think about BIM in a fabrication context -- catching coordination issues before they become field problems.

### Who This Fits

SDG's stated client profile is steel fabricators, structural contractors, EPC firms, and engineering consultants. That is a reasonably specific niche. The work is fabrication-first -- their language around "fabrication-ready drawings" and "model-to-drawing coordination" suggests they understand that the downstream user of these documents is a fabricator or ironworker, not just a designer.

For a small-to-mid-size fabrication shop in the US or UK that needs drawing production capacity but cannot justify a full in-house detailing team, an offshore drafting partner like SDG is a realistic option. The cost advantage of India-based engineering labor is well established -- I would estimate offshore engineering drafting runs somewhere in the $8 to $16 per hour range for qualified detailers, compared to $35 to $60 or more for US-based staff. The tradeoff is timezone lag, revision communication overhead, and the need for a strong internal reviewer on your side.

### Delivery Model and Locations

The phone number on the site carries an Indian country code (+91), and the company operates under an US-facing brand name. This is a common model for India-based engineering services firms targeting North American and European buyers. Expect a significant timezone gap if you are US-based -- India Standard Time is 9.5 to 13.5 hours ahead of US time zones depending on where you sit. That matters for revision turnaround and live coordination calls.

The site does not publish team size, and I would recommend asking directly on your first call. Knowing whether SDG runs 5 detailers or 50 changes how you think about their capacity for surge projects and parallel workstreams.

### QA and Process

SDG mentions "structured QA/QC" and "accuracy, consistency and revision control" as core features. That is standard vendor language -- every detailing firm says this. The things I would actually probe: What is the internal check process before drawings are issued? Is there a senior reviewer separate from the production detailer? What is the typical revision cycle on a shop drawing package? Do they use Tekla, SDS/2, or Revit, and does that match your fabrication shop's preferred workflow?

Software compatibility matters in structural detailing more than most outsourcing categories. A shop drawing produced in one platform may not translate cleanly to another, and model handoffs between detailer and fabricator have real coordination risk if the platforms do not align.

### Compliance and Security

No certifications are listed on the site. For engineering drafting work, the relevant concerns are data handling (particularly for clients sharing proprietary design files), NDA coverage, and IP ownership. These are contractual rather than certification-based for most drafting engagements, but confirm in writing before sharing design inputs.

### Editor's Take

SDG is a focused technical outsourcing firm, not a broad BPO. If you are looking to outsource structural steel detailing or BIM production work to an India-based team, they are worth evaluating. The range of services -- steel, miscellaneous metals, connections, MEP, BIM -- is broader than a pure-play detailer, which could be useful for multi-discipline projects or could mean thinner expertise spread across too many areas. Ask for project samples specifically in your sector (industrial vs. Commercial vs. Residential) and in your preferred software platform before committing.

The US-facing branding with Indian contact details is common and not a red flag on its own, but it does mean you should set expectations clearly around communication hours and revision turnaround. Build in a buffer day for asynchronous feedback cycles. Confirm headcount and the specific detailers who would be assigned to your account -- not just a general capability overview.
