Service Overview

2D CAD Drafting Services

Our drafting team produces discipline drawings for process plants to client and project standards in AutoCAD, AutoCAD Plant 3D P&ID, MicroStation and SmartPlant P&ID. Drawings are produced under engineering supervision and checked before issue, so that they are technically correct as well as well presented.

We support new design, redline incorporation after construction and conversion of legacy paper or raster drawings into clean, intelligent CAD.

  • Your standardsTitle blocks, layers and symbols applied.
  • Checked before issueIndependent check against engineering input.
  • Legacy to CADRaster, PDF and paper converted accurately.
  • Scalable capacityExtra drafters for peak workloads.

Conversion & As-builts

Legacy drawings digitised

Paper, scanned and PDF drawings are converted into accurate CAD, and site redlines are incorporated to create a reliable as-built record.

  • Raster / PDF / paper to vector CAD conversion
  • Dumb-to-intelligent P&ID conversion
  • Redline and field-change incorporation
  • Drawing standardisation, renumbering and clean-up
  • Master drawing registers and revision control
Quality & Delivery

Checked, consistent output

A structured checking process and flexible capacity allow fast turnaround without compromising quality.

  • Independent drawing check against engineering input
  • Consistent layers, text styles, dimensions and plot styles
  • Batch plotting, PDF sets and transmittals
  • Scalable team for peak workloads and multiple time zones
FAQ

Frequently asked questions

Which CAD platforms do you use?

AutoCAD, AutoCAD Plant 3D P&ID, MicroStation and SmartPlant P&ID, delivered in the version your organisation uses.

Can you convert dumb P&IDs into intelligent P&IDs?

Yes. We convert legacy P&IDs into intelligent P&IDs with tagged equipment, lines and instruments that can generate line lists and indexes.

Will the drawings follow our standards?

Yes. We apply your title blocks, layers, symbols, fonts and numbering, and set up templates at the start of the assignment.

How is quality checked?

Every drawing is checked against the engineering input by a second person before issue, using a checklist for your standards.

What turnaround can you offer?

This depends on volume and complexity; we agree a delivery schedule per batch and can scale the team for urgent work.
