Grey Structure Construction in Karachi
AEC executes grey structure construction across Karachi under PEC Licence No. 17347, covering the shell from foundation to roof slab. Projects run up to Rs. 200 million, with structural work completed for private clients in DHA and institutional clients including NED University and PWD.
Advanced Engineering & Construction executes grey structure construction in Karachi under PEC Licence No. 17347, Category C4/E, covering foundation, framing, and slab work up to Rs. 200 million in construction cost. The scope runs under PEC specialization codes BC01 and BC02 for building construction, with civil engineering work under codes CE08, CE09, and CE10. AEC has carried out this structural phase for institutional clients including NED University of Engineering & Technology and Jinnah Sindh Medical University.
Grey structure is the structural phase of a building — foundation, columns, beams, slab, and brickwork — completed before any finishing trade begins. Electrical work, plumbing, flooring, false ceiling installation, kitchen remodeling, bathroom renovation, and glass and aluminum cladding run on their own dedicated service pages and are not part of this scope. AEC delivers each of these trades separately once the structural frame is complete. Explore the complete range of construction and renovation services AEC offers across Karachi, from grey structure through to final finishing.

What Grey Structure Construction Includes
Grey structure construction covers site excavation, foundation casting, column and beam framing, slab work floor by floor, and brickwork up to roof level. Soil testing is carried out before foundation design wherever ground condition is uncertain, which matters most on reclaimed or coastal land.
| Component | Scope |
|---|---|
| Foundation & footing | Excavation, concrete, steel reinforcement |
| RCC columns & beams | Load-bearing structural frame |
| Roof slab | Cast per floor before brickwork |
| Brickwork & block work | Wall infill between the frame |
| DPC & basic waterproofing | Damp protection at foundation level |
Karachi’s soil varies between reclaimed coastal land and inland plots, and foundation depth changes accordingly. A property near Clifton or DHA often needs a different footing design than one in Gulistan-e-Johar or North Karachi. Each stage is inspected before the next begins, since structural errors at this phase are costly to correct later.

How AEC Executes Grey Structure Work
AEC follows a fixed sequence on every grey structure project: excavation and soil verification, foundation casting, column and beam framing, slab casting floor by floor, and brickwork infill. Each stage is inspected before the next begins, since a structural fault discovered after the next floor is cast is far more costly to fix than one caught at the same stage.
The most common technical risk in grey structure work along Karachi’s coastal belt is not the concrete mix itself but inadequate curing time before formwork removal. High humidity slows visible surface drying without guaranteeing the concrete has gained sufficient strength underneath, and removing formwork too early on this assumption is a frequent cause of cracking in Karachi construction. AEC holds formwork in place for a fixed minimum period regardless of how dry the surface appears, based on concrete grade and ambient temperature at the time of casting.
Grey Structure Cost in Karachi
| Coverage | Grey Structure Rate (PKR/sq ft) |
|---|---|
| DHA Karachi specifically | 2,600 – 3,200 |
| Karachi, city-wide | 3,200 – 3,800 |
| Pakistan major cities average | 2,800 – 3,500 |
Grey structure construction in Karachi typically costs between Rs. 2,800 and Rs. 3,800 per square foot, depending on structural design, steel reinforcement ratio, and soil condition at the site. A site requiring deeper foundations due to reclaimed or coastal soil sits toward the higher end of this range, since additional excavation and concrete volume add directly to cost. This range covers structural work only — foundation, framing, and slab — and does not include finishing, electrical, or plumbing.
PEC Licence and Credentials Behind This Work
Advanced Engineering & Construction holds PEC Licence No. 17347, Category C4/E, issued under the Construction and Operation of Engineering Works Bye-laws 1987 and valid through 30 June 2026. This licence permits AEC to undertake civil construction works up to Rs. 200 million, covering the foundation, structural, and grey structure work described on this page. AEC has delivered structural civil works for institutional clients including Pakistan Works & Development (PWD) and NED University of Engineering & Technology — clients whose procurement processes require verified PEC registration before a contractor is engaged for structural work.
Why AEC for Grey Structure Work in Karachi
AEC documents structural drawings and soil reports on the project file before work begins, not only when a client asks for them.
| What’s Common Among Unregistered Karachi Contractors | What AEC Provides |
|---|---|
| Foundation depth set by habit, not soil testing | Foundation design checked against site soil condition |
| No PEC licence on file | Work executed under PEC Licence No. 17347, Category C4/E |
| Verbal cost estimate before drawings exist | Quote issued against structural drawings or soil report |
| Formwork removed once the surface looks dry | Formwork held for a fixed minimum cure period by concrete grade |
Our Projects
Building a New Home or Renovating an Existing One?
If your project is a full new build from foundation to handover, AEC’s construction services in Karachi cover the complete process including SBCA approval and finishing. If your property already has a finished grey structure and needs flooring, electrical, plumbing, or finishing work, AEC’s home renovation services in Karachi cover that scope instead.

Frequently Asked Questions
Is AEC a PEC-licensed contractor for grey structure work in Karachi?
Yes, AEC holds PEC Licence No. 17347, Category C4/E, valid through 30 June 2026, including the BC01 and BC02 specialization codes relevant to grey structure and building construction. The licence permits civil construction works up to Rs. 200 million.
How much does grey structure construction cost in Karachi?
Grey structure construction in Karachi typically ranges from Rs. 2,800 to Rs. 3,800 per square foot, depending on structural design, steel reinforcement, and soil condition. This range covers foundation, framing, and slab work only, not finishing, electrical, or plumbing. AEC provides a project-specific quote after reviewing structural drawings or a soil test report.
Does foundation design change for coastal or reclaimed land in Karachi?
Yes, AEC adjusts foundation depth and design based on the site’s soil report, which matters most on reclaimed or coastal land near areas like DHA and Clifton. Foundation work on weaker soil typically costs more due to additional excavation and concrete volume.
What is the difference between grey structure construction and home renovation?
Grey structure construction covers new structural work — foundation, framing, and slab — for buildings being built from the ground up. Home renovation covers finishing, electrical, plumbing, and layout work on properties that already have a completed structure. AEC offers both, under separate scopes and quotes.
What size of project can AEC take on under its current PEC licence?
AEC’s PEC Licence No. 17347, Category C4/E permits construction projects up to Rs. 200 million in cost, covering most residential and mid-scale commercial grey structure projects in Karachi. Projects beyond this value would require licence category upgrade confirmation.
