Engineering Services in Pakistan

Three engineering services under one roof in Rawalpindi: metal fabrication, CNC machining and CAD design. Vertically integrated - drawings produced in-house, parts machined to ±0.005 mm, structures welded by AWS / ASME-qualified welders, and the same QA dossier follows the job from concept to dispatch.

Full-Service Engineering in Pakistan - What That Looks Like

Pakistan's engineering services market is split between EPC giants (Descon, HMC Taxila) handling refinery and power-plant scope, and thousands of small workshops doing piece-meal welding or single-machine work. The middle - medium-volume, drawing-driven, quality-documented engineering - is thinly served. That is the gap Unitec operates in.

Three services run as one capability:

  • CAD Design turns a sketch, sample or concept into shop-floor-ready drawings.
  • CNC Machining produces precision components from those drawings.
  • Metal Fabrication welds and assembles those components into finished structures.

You can buy any one of the three on its own, or chain all three together for projects where a single supplier owning the full chain is the difference between an on-time delivery and a finger-pointing exercise.

Frequently Asked Questions

What engineering services does Unitec offer?

Three core services run from our Rawalpindi shop floor: metal fabrication (structural steel, pipe spools, sheet metal, custom assemblies, PEB), CNC machining (3-axis and 5-axis milling, turning, prototyping to ±0.005 mm tolerances) and CAD design (2D drawings, 3D modelling, reverse engineering and production-ready documentation).

Can the three engineering services run together on one project?

Yes - and they often do. A typical combined job: CAD desk produces drawings from a sketch or sample, CNC shop machines the precision components, and the fabrication bay welds them into a finished assembly. One delivery manager owns the chain, one inspection dossier covers the whole job.

What materials and quality standards do you work to?

Materials cover the full range: mild steel, stainless (304/304L/316/316L/410/17-4 PH), tool steel (D2/O1/H13), aluminum (6061/7075/5052), brass, copper, GI, Corten, plus imported specialty alloys (Inconel, Hastelloy, duplex SS, titanium). QA is ISO 9001:2015-aligned with welders qualified per AWS D1.1 / ASME Section IX, in-house VT/PT/MT and partner UT/RT NDT.

Do you deliver across Pakistan?

Yes. Last-mile delivery to all major Pakistani cities - Lahore, Faisalabad, Multan, Peshawar, Karachi and Quetta. Truck cost depends on dimensions and tonnage and is quoted as a separate line on the invoice. Oversize and over-height loads are moved with NHA route clearances arranged in advance.

What's the typical lead time on engineering work?

CNC prototypes 5–10 working days. Small fabrication jobs 7–10 working days. Medium PEB and shed work 4–6 weeks including shop drawings. Large piping spools or pressure-class vessels 6–10 weeks. CAD-only work 2–4 weeks for a complete drawing pack from sketch.
