Planning the roof slab (commonly called lanter in Pakistan) is one of the biggest grey-structure expenses for a 5 Marla house. Based on a typical 25 × 50 ft plot, an assumed 1,125 sq.ft RCC roof slab, our existing RCC slab calculator methodology, and September 2026 market references, a practical working budget is around Rs. 8.0 lakh. Actual cost can vary by city, structural design, steel detailing, material brand, transport and labour.
5 Marla Slab Cost September 2026 — Quick Answer
For a typical 1,125 sq.ft RCC roof slab, the estimated complete cost is approximately Rs. 804,605, or about Rs. 715 per sq.ft, using the working rates and quantities shown below. Keep a contingency because steel, cement, sand and aggregate prices can change quickly.
Project Assumptions
- Plot size: 25 × 50 ft (5 Marla)
- Estimated slab area: 1,125 sq.ft
- Slab type: RCC roof slab / lanter
- Steel: Grade 60 reinforcement, subject to structural design
- Concrete materials: Cement, sand and crush/aggregate
- Estimate period: September 2026
Important: This is a budgeting estimate, not a structural design or BOQ. Final reinforcement, slab thickness, beam sizes and concrete grade must follow the structural drawings and engineer’s specifications.

| Electrical conduits & slab work | Lump sum | — | Rs. 40,000 |
| Shuttering / formwork | 1,125 sq.ft | Rs. 55/sq.ft | Rs. 61,875 |
| Concrete mixing, pouring & labour | Lump sum | — | Rs. 40,000 |
| Steel fixing labour | 1,125 sq.ft | Rs. 20/sq.ft | Rs. 22,500 |
| Binding wire, polythene & miscellaneous | Lump sum | — | Rs. 10,000 |
| Estimated Total | Rs. 804,605 | ||
Estimated Cost Per Square Foot
Rs. 804,605 ÷ 1,125 sq.ft = approximately Rs. 715 per sq.ft.
For safer budgeting, homeowners may keep approximately Rs. 8.0–8.5 lakh available for a similar slab because local rates, transport, site conditions and reinforcement design can change the final bill.
1. Steel Cost for a 5 Marla Slab
Using approximately 1,250 kg of reinforcement and a working rate of Rs. 300/kg, steel contributes about Rs. 375,000. Steel is normally the largest single component of slab cost. The exact quantity must come from the bar bending schedule or structural drawings; do not reduce reinforcement simply to match a thumb-rule estimate.
2. Cement, Sand and Crush Cost
For comparison with our earlier 5 Marla slab estimate, this update uses approximately 105 cement bags, 248 cft sand and 429 cft crush. At the September 2026 working rates used here, these three concrete ingredients total approximately Rs. 255,230. Material source and delivery distance can cause substantial differences between cities.
3. Shuttering and Labour
At Rs. 55 per sq.ft, shuttering for 1,125 sq.ft is estimated at Rs. 61,875. We have also allowed Rs. 40,000 for concrete mixing/pouring labour and Rs. 22,500 for steel fixing. Labour arrangements vary considerably, so obtain a site-specific quotation before casting.
4. Electrical Conduits and Miscellaneous Work
Electrical conduits, fan boxes and related slab-stage work are allowed at approximately Rs. 40,000. Another Rs. 10,000 is included for binding wire, polythene and small miscellaneous items. More electrical points or special conduit layouts can increase this allowance.

September 2026 Market Rate Note
Market references checked in September 2026 show meaningful variation by city, supplier and material specification. Published references place cement around the mid-Rs.1,000s per bag in some markets, while reinforcement steel quotations can approach roughly Rs.300/kg depending on bar size and supplier. Sand and crush rates vary even more because transport distance and source strongly affect delivered cost. For this reason, the table above uses rounded working rates suitable for a planning estimate rather than claiming one nationwide fixed price.
Comparison With April 2026
Our April 2026 5 Marla slab example was approximately Rs. 685,258 for 1,125 sq.ft. Using the September working assumptions above, the estimate becomes about Rs. 804,605. The difference is approximately Rs. 119,347, mainly reflecting updated working rates for reinforcement, concrete materials, shuttering and labour. Read the earlier 5 Marla slab cost example for the previous breakdown.
What Can Change the Final Slab Cost?
- Structural design: Beam sizes, spans, slab thickness and reinforcement ratio directly affect quantities.
- Steel and cement brands: Brand, grade and dealer quotations vary.
- City and transport: Sand and aggregate delivered rates are highly location-dependent.
- Shuttering system: Rental, labour and support arrangement affect formwork cost.
- Concrete method: Site mixing, mixer labour or ready-mix/pump arrangements have different costs.
- Electrical layout: Additional conduits, fan boxes and points increase embedded-work cost.
Important Checks Before RCC Slab Casting
Before pouring concrete, the site engineer should check reinforcement diameter and spacing, development/anchorage, concrete cover, beam reinforcement, electrical conduits and fan boxes, shuttering line and level, supports, openings and sleeves. Concrete should be properly mixed, compacted with appropriate vibration and cured according to the project specification. Never alter reinforcement or structural dimensions only to reduce cost.
Frequently Asked Questions
How much does a 5 Marla slab cost in Pakistan in September 2026?
For the 1,125 sq.ft example in this guide, the working estimate is approximately Rs. 804,605 (about Rs. 8.05 lakh), excluding unusual structural or site-specific requirements.
What is the estimated RCC slab cost per sq.ft?
The example works out to approximately Rs. 715 per sq.ft. Your actual rate may be higher or lower depending on design and local prices.
How much steel is used in this 5 Marla slab example?
This estimate uses approximately 1,250 kg, consistent with our earlier 5 Marla cost example. The actual reinforcement must be calculated from approved structural drawings.
Does 5 Marla always mean a 1,125 sq.ft slab?
No. Plot size and covered/slab area are different. This article uses 1,125 sq.ft as a practical example. Enter your actual slab area in the RCC Slab Cost Calculator for a more relevant estimate.
Does this estimate include beams?
The cost is a practical roof-slab budgeting example based on the quantities used in our slab-cost methodology. Structural beam and reinforcement requirements vary by design, so the engineer’s BOQ and drawings should control the final quantity.
Final Estimate
For budgeting in September 2026, a typical 1,125 sq.ft 5 Marla RCC roof slab can be planned at roughly Rs. 8.05 lakh using the assumptions in this guide, with a prudent working budget of around Rs. 8.0–8.5 lakh. Always update supplier quotations immediately before purchasing materials and use approved structural drawings for actual construction.
