Quick answer: The difference between A, A+ and A++ grey-structure packages is not simply a label. It comes from the written specification for cement brands, sand and crush sources, concrete and mortar ratios, termite protection, foundation treatment, pipe brands, tank construction and additional roof-protection work.
This guide explains the Planet Builders material-comparison sheet in clear language. It is a scope-comparison guide, not a structural design document. Final mix designs, member sizes and construction details must always follow engineer-approved drawings, soil conditions and the signed bill of quantities (BOQ).
A vs A+ vs A++ Grey Structure at a Glance
| Material or work | A package | A+ package | A++ package |
|---|---|---|---|
| Bricks | Grade-A awal bricks | Grade-A awal bricks | Grade-A awal bricks |
| Cement | PS-232-2008 (R), Grade 43; available approved brand | Lucky or Cherat | D.G., Bestway or Maple Leaf |
| Roof-slab sand | Ravi sand | Chenab sand | Chenab sand |
| Wall-masonry sand | Ravi sand | Ravi sand | Chenab sand |
| External-plaster sand | Ravi sand | Ravi sand | Chenab sand |
| Termite proofing | Not stated on the comparison sheet | 5-year warranty | 10-year warranty |
| Foundation PCC | 1:6:12 | 1:4:8 | 1:2:4 |
| Horizontal RCC slab | 1:3:6 | Printed ratio requires written clarification | 1:2:4 |
| Vertical wall | Parapet wall | Parapet wall | RCC wall |
| Crush | Sargodha | Margalla | Plant-produced Margalla |
1. Bricks, Cement and Brick Ballast
All three packages specify Grade-A awal bricks, so the main differences begin with the named cement options and brick-ballast quality.
- A package: Cement meeting the stated PS-232-2008 (R), Grade 43 specification, using an available approved brand. Brick ballast is listed as mixed quality.
- A+ package: Lucky or Cherat cement with first-class brick ballast.
- A++ package: D.G., Bestway or Maple Leaf cement, with the brick-ballast source identified on the original comparison sheet.
A professional contract should name the exact approved brand or an agreed equivalent, define how substitutions are approved, and require fresh, properly stored cement. Brand names alone do not replace batch checks, correct mixing, compaction and curing.
2. Sand for Slabs, Masonry and Plaster
The source sheet distinguishes between Ravi and Chenab sand according to the work and package:
- For roof slabs, the A package specifies Ravi sand, while A+ and A++ specify Chenab sand.
- For wall masonry and external plaster, A and A+ specify Ravi sand, while A++ specifies Chenab sand.
- The printed wall and roof plaster ratios progress from 1:6 in A to 1:5 in A+ and 1:4 in A++.
Before work begins, the BOQ should also define sand cleanliness, grading, silt limits and approval procedures. A source name is useful, but material acceptance should still depend on quality at delivery.
3. Foundation Work, DPC and Termite Treatment
The comparison sheet lists termite treatment at the foundation and before ground-floor flooring. The A+ package carries a 5-year warranty and the A++ package a 10-year warranty; no warranty is stated for the A package.
Foundation plain-cement-concrete (PCC) ratios are shown as 1:6:12 for A, 1:4:8 for A+ and 1:2:4 for A++. The sheet also refers to double DPC and varying internal-side foundation-plaster thicknesses and ratios. Because the layout combines several rows, these details should be restated clearly in the signed BOQ rather than inferred from the comparison table.
4. Foundation Infill and Masonry-Wall Ratios
- Foundation infill: Mixed ghusso is listed for A, with Ravi ghusso listed for A+ and A++.
- 9-inch masonry walls: A cement-to-sand ratio of 1:6 is shown across all packages.
- 4-inch masonry walls: A and A+ show 1:5, while A++ shows 1:4.
Wall thickness, reinforcement, bonding, curing and opening details must remain consistent with the architectural and structural drawings. Mortar ratio is only one part of good masonry.
5. RCC Slabs, Beams, Shades and Vertical Walls
The document states that horizontal RCC slabs use cement, sand and crush mixed mechanically and vibrated. It prints a 1:3:6 ratio for A and 1:2:4 for A++. The A+ ratio is not clearly typeset in the source PDF and should be confirmed in writing before pricing or construction.
The same package ratios are referenced for beams and shades. Vertical-wall construction is listed as a parapet wall for A and A+, and an RCC wall for A++. Window shades and 2-inch storage or counter slabs are noted as following the relevant package specification.
Important: Structural concrete must follow the engineer-approved mix design and drawings. Never select a structural mix solely from a marketing-tier table.
6. Sewage, Ducting and Pipe Brands
The internal and external sewage section includes grey-floor PCC, UPVC ducting and example pipe brands:
- A package: PCC 1:3:6 with local or national-brand pipes.
- A+ package: A stronger printed PCC specification with G.M., Turk Plast or Dura pipes.
- A++ package: Popular or Dura pipes are listed.
The A++ PCC ratio printed in the source table does not follow the apparent package progression, so it should also be clarified in the final BOQ. Pipe diameter, class, fittings, slopes, testing and approved brand are more useful contract controls than a brand list alone.
7. Water Tanks and Crush Quality
The A package lists tank construction in brick masonry. A+ adds a 4-inch brick wall, 4-inch RCC slab and internal plain plaster. A++ lists similar wall and slab construction with internal marble-crush plaster.
For aggregate, the comparison identifies Sargodha crush for A, Margalla crush for A+, and plant-produced Margalla crush for A++. Aggregate should still be checked for grading, cleanliness and suitability for the approved concrete design.
8. Additional Work Included in A++
The note on the comparison sheet states that the following items are added only in A++ quality work:
- Window safety grills
- Top-roof insulation or heat proofing
- Waterproofing
It also references the septic tank, underground water tank and overhead water tank. Their exact dimensions, reinforcement, waterproofing and finishes should be documented in the drawings and BOQ.
How to Compare Grey-Structure Quotations Properly
- Compare line by line: Two quotations with the same “A+” label may include very different materials and quantities.
- Demand named specifications: Record brands, approved alternatives, ratios, thicknesses, warranties and testing requirements.
- Resolve unclear entries: Correct every typing or layout ambiguity before signing the contract.
- Use an itemized BOQ: Connect each specification to a measurable quantity, rate and payment milestone.
- Keep engineering authority clear: Structural drawings and the project engineer take precedence over general package descriptions.
- Inspect materials on delivery: Verify bricks, cement, sand, crush, pipes and treatment chemicals before use.

Frequently Asked Questions
What is the difference between A, A+ and A++ construction packages?
The difference lies in the written material and work specifications, including cement options, sand and crush sources, concrete and mortar ratios, termite-treatment warranty, pipe brands, tank construction and additional protection work.
Does A++ automatically mean the building is structurally safer?
No package label replaces structural design. Safety depends on engineer-approved drawings, soil conditions, reinforcement, concrete quality, workmanship, testing and supervision. A++ may describe upgraded materials or scope, but the structural engineer's requirements remain controlling.
Which package includes waterproofing and roof insulation?
In the supplied Planet Builders comparison sheet, window safety grills, top-roof insulation or heat proofing, and waterproofing are listed as additions to A++ quality work.
Why should unclear mix ratios be corrected before signing?
A typing or formatting error can change the meaning of a concrete specification. Every unclear ratio should be rewritten unambiguously in the BOQ and confirmed by the structural engineer before pricing, procurement or construction.
What should a grey-structure BOQ include?
It should define measurable quantities, brands or approved equivalents, material grades, mix requirements, wall and slab details, treatment warranties, pipe classes, testing, exclusions, payment milestones and the drawing revision that governs the work.
