Services

What we draft under your engineers

Production support for civil and structural firms that need clean sheets on a deadline — scoped before work starts.

Site & civil plans

Site plans, roadwork, concrete structures, and drainage drawn to spec in AutoCAD, Civil 3D, and MicroStation.

Structural detail & BIM

Framing plans, sections, retaining details, and BIM coordination for bridge, civil, and structural projects.

Markup & QA review

Bluebeam markup passes against design specs before final delivery — catch changes early, not after the set is locked.

Sketch to drawing

Hand sketches and engineer markups converted into clean PDF or native CAD deliverables in your preferred format.

Process

Overflow that stays under your PE

Four clear steps from first files to deliverables ready for your stamp or handoff.

  1. Project setup

    Send sketches, markups, or a short description. We confirm sheet count, tools, and turnaround before anything starts.

  2. Draft

    Drawings built to your standards in Civil 3D, AutoCAD, MicroStation, or Revit — matched to your existing files.

  3. Review

    You receive a PDF to markup while the work is still easy to change.

  4. Deliver

    Final files land in your preferred format on the timeline agreed at scope — ready for your PE to issue or hand off.
