Design subcontracting for B2B projects

Production-ready design for stairs, railings and steel details

Engineering Partner supports contractors, fabricators and project teams with 3D models, detail drawings, assembly drawings, production drawings and technical bid-phase support.

Who it's for
Project leads, estimators and production managers who need structured design capacity — for overflow work, bid-phase packages or drawing cleanup.
Output
DWG/PDF drawing packages, connection details, material lists, 3D model support — all production-ready.

Structured drawing output for every stage of your project

All services are project-based. Every inquiry receives a clear definition — what is in scope, what is not, and what the deliverable will be. This makes starting a collaboration low-risk for both sides.

Included scope
  • 3D models and assemblies for stair, railing and mixed steel details
  • Detail drawings and node solutions for practical production use
  • Assembly drawings and production drawings with revision discipline
  • Material lists and component breakdowns when included in project scope
  • Technical bid-phase support for early feasibility and design clarity
  • Drawing clean-up and package standardization for internal handover quality

No pitches. Scope first, drawings second.

01

We speak the same language

Communication happens in technical language: scope, extent, revisions, annotations.

02

Drawings that go straight to production

We produce documentation that is ready for production use. No need to clean things up before passing them on.

03

Start small

Send one package. We will see if we are a good fit. We only scale up when both sides are satisfied with the output.

Simple enough for a pilot, structured enough for repeat work

The first inquiry requires no major commitment. Send one file, receive a clear response on scope and timeline — and decide for yourself whether to continue.

01

Send input

Share PDF, DWG, STEP, sketches or a short written brief. Existing package quality does not need to be perfect.

02

Scope review

We review what is needed, clarify deliverables, highlight exclusions and propose a realistic first assignment.

03

Delivery

Drawings, model outputs and detail solutions are delivered according to agreed package scope and timeline.

04

Next step

Continue with revisions, a larger package, or a second pilot. Cooperation can scale only when trust is earned.
