Constructing a home or commercial building in Multan requires a solid understanding of the civil grey structure phase. The grey structure represents approximately 40-45% of your total construction expenditure and dictates the lifetime safety of your building.
1. Core Material Requirements for Multan Civil Works
The core components of any reliable grey structure include certified steel reinforcement, first-class red clay kiln bricks, cement, sand, crushed stone aggregate, and plumbing/electrical conduits.
- Grade 60 Deformed Steel: For a 10 Marla double-story house (covered area ~3,200 sq ft), expect approximately 8.5 to 9.5 tons of Grade 60 steel rebar.
- Cement Bags: Between 950 to 1,150 bags of fresh OPC cement (Maple Leaf, DG, or Bestway) for concrete raft, columns, slabs, and brick mortar.
- A-Grade Bricks: Approximately 70,000 to 80,000 solid red bricks fired in circular kilns.
- Sand: Washed Chenab river sand for mortar and plastering to prevent salt efflorescence.
2. Engineering Supervision vs. Casual Subcontractors
The greatest risk in Multan construction is casual contractor compromises: substituting Grade 40 rerolled steel for Grade 60, reducing steel spacing from 6-inch centers to 9-inch centers, and inadequate 14-day water curing protocols. Always ensure daily civil engineer oversight.
3. Protecting Against Multan Soil Dampness (Sem/Shor)
Multan’s alluvial ground conditions demand a multi-layered Damp Proof Course (DPC). At Mahar Builders, we execute a continuous 1.5-inch 1:2:4 concrete DPC with crystalline waterproofing admixture, coated with double bituminous bitumen and heavy 500-gauge polythene membrane before raising brick walls.
