Grey structure is the stage that decides whether a building lasts. Once the finishing goes on, nobody can see the steel, the concrete mix, or the foundation — but those are exactly the things that carry the load, resist the heat, and keep the house standing through decades of South Punjab summers and monsoons. Stone Heaven Constructions builds grey structure inside DHA Bahawalpur as a specialist discipline, not a formality to rush through before the visible work begins.

Because we work on a with-material basis only, we take responsibility for every input that goes into the shell of your building. We supply the steel, cement, bricks, sand, aggregate, and waterproofing materials ourselves. We do not accept labour-only contracts, and we do not build with client-supplied materials — that is the only way to guarantee that what is buried inside the walls and foundation actually meets the required standard.

The RCC Framework We Build

The reinforced cement concrete (RCC) framework is the load path of the whole structure. Loads travel from the roof slab, through the beams, down the columns, and into the foundation. If any link in that chain is under-designed, the building tells you eventually — through cracks, settlement, or worse. We build the framework with Grade-60 deformed steel rebar from established mills such as Mughal and Amreli, tied and placed according to structural drawings rather than by eye.

Raft Footing & Foundation

A raft foundation spreads building load across the plot, which suits the sandy soil and variable water table found in parts of DHA Bahawalpur.

Columns & Beams

Grade-60 steel columns and beams sized for the structure, tied correctly and cast with controlled concrete.

Roof Slab Casting

Slabs cast with proper mix ratios and curing schedules planned around the weather to avoid heat cracking.

Materials and Structural Standards

Material selection is where grey structure quality is won or lost. Our standard specification includes:

  • Grade-60 steel rebar (Mughal / Amreli) for columns, beams, and slabs.
  • A-Awwal kiln-burnt bricks for masonry that handles heat and moisture.
  • DG Khan / Maple Leaf OPC cement for consistent concrete strength.
  • Underground water tank and sewerage lines built into the structure.
  • Termite barrier — a chemical soil treatment applied at foundation stage, because termite activity in South Punjab soil is a genuine risk to any building.
  • Waterproofing and DPC to keep rising damp and monsoon water out of the structure.

Testing and Supervision

We do not ask you to take our word for it. Soil bearing tests inform the foundation design, and concrete cube strength testing confirms that the concrete poured on site actually reaches the required strength. A resident engineer supervises the work — checking steel placement before pours, verifying mix ratios, and enforcing curing schedules. This supervision matters most in summer, when concrete can cure too fast and lose strength if it is not managed correctly.

What Grey Structure Includes — and What It Does Not

Grey structure covers the complete structural shell: foundation, framework, roof slabs, masonry walls, concealed plumbing and electrical conduits, underground tank, sewerage, termite barrier, and waterproofing. It does not include finishing work — tiles, paint, doors, kitchen, and sanitary fittings all belong to the finishing stage. Many owners build grey structure first and finish later as budget allows, which is perfectly workable. If you would prefer a single contract that carries the building all the way to a move-in condition, our turnkey construction service continues from exactly this point.

Grey structure is also the natural starting point for larger builds. On bigger plots, the foundation and framework carry more load and demand more careful planning, which is why 1 Kanal house construction deserves its own structural approach. Whatever the size, the principle is the same: get the shell right, and everything after it becomes easier. You can see how grey structure fits into our DHA construction services as a whole.

With-material only: every input in your grey structure — steel, cement, bricks, and waterproofing — is supplied by Stone Heaven Constructions. We do not build labour-only or with client-supplied materials.

Frequently Asked Questions

What materials are used in grey structure construction?
Grade-60 deformed steel rebar (Mughal / Amreli), first-class A-Awwal kiln-burnt bricks, DG Khan or Maple Leaf OPC cement, washed sand and graded aggregate, plus waterproofing and DPC materials. We supply all of it on a with-material basis.
What is included in grey structure work?
The structural shell: raft foundation, RCC columns and beams, roof slab casting, brick masonry, underground water tank, sewerage, termite barrier, and waterproofing. Finishing such as tiles, paint, and fittings is separate.
Does grey structure include plumbing and electrical conduits?
Yes. Concealed plumbing and electrical conduits are laid within the structure at the grey stage, so finishing can proceed later without breaking walls. The fittings and fixtures themselves are installed at finishing stage.
How long does grey structure take for a 10 Marla house?
For a typical 10 Marla double storey home it usually takes a few months, depending on storeys, basement, weather, and curing schedules. Summer heat and the monsoon affect concrete curing, so we confirm timelines against your specific design.
