Practical project support.

For engineering teams, contractors, and facility owners who need well-organized electrical designs and dependable drafting support.

01 / OUR SERVICES

From the electrical concept
to the drawing details.

Bring us a new scope, an existing drawing set, or a stack of markups. We’ll help define the next deliverable.

01

Electrical design

Develop the power distribution and electrical documentation your project needs, with attention to equipment interfaces and a clear design basis.

  • Single-line diagrams & distribution layouts
  • Load summaries & equipment schedules
  • Feeder, conduit & cable schedules
  • Design coordination & drawing notes
02

AutoCAD drafting

Turn engineering direction into organized, editable drawings. Extend your team’s drafting capacity while keeping your standards at the center.

  • Redline incorporation & drawing revisions
  • PDF-to-CAD drawing recreation
  • Layouts, details & sheet set organization
  • Title blocks, layers & CAD standards
03

Controls documentation

Connect the equipment, signals, and interfaces with electrical documentation that supports installation, coordination, and future maintenance.

  • Control panel layouts & schematics
  • I/O schedules & wiring diagrams
  • Interconnection & network diagrams
  • Instrumentation & control drawing updates

02 / WHAT YOU RECEIVE

A drawing package.
Built around your scope.

Useful deliverables start with an agreed drawing list, defined inputs, and clear review milestones.

Representative scopes. Final deliverables and file formats are agreed for each project.

EXAMPLE / POWER DISTRIBUTION

03 / HOW WE WORK

Clear scope.
Deliberate execution.

A straightforward process that keeps technical decisions, reviews, and deliverables moving together.

  1. 01 / DEFINE

    Align on the scope.

    Review your inputs, project requirements, existing drawings, and target schedule. Agree on the drawing list and scope boundaries.

  2. 02 / DEVELOP

    Build the package.

    Develop the design and drawings around your standards. Surface questions and coordinate equipment and system interfaces.

  3. 03 / REVIEW

    Resolve the details.

    Work through the agreed review milestones, incorporate comments, and reconcile the drawing package.

  4. 04 / DELIVER

    Hand over clearly.

    Provide the agreed editable files and PDF set, with organized revisions and supporting schedules.

Defined deliverables. Fixed-price milestones.

We favor clearly bounded work packages so you know what’s included, when reviews happen, and what the final handoff contains.

04 / TECHNICAL FOUNDATION

Engineering experience.
Drawing-level attention.

O’Quinn Technical Services LLC provides electrical design and drafting support led by Wesley O’Quinn, PhD in Electrical Engineering.

Wesley’s background spans nuclear power instrumentation and controls, electrical design, and semiconductor controls design. That experience informs a practical approach to power systems, industrial interfaces, and technical documentation.

Whether you need a defined drawing package or support for your existing team, the focus is the same: clear communication, coordinated details, and files you can continue to use.
