How to Accurately Calculate the Materials Delivered by Dumpers in Pakistan
Avoid Quantity Fraud, Protect Your Budget, and Build with Confidence
Whether you're constructing a home in Islamabad, a school in Lawrencepur, or a plaza in Hasnabdal, one thing is certain: accurate delivery of construction materials is critical to your project's success. Materials like sand, crush, bajri, bajjar, bricks, stone dust, filling sand, and ghassu are typically transported by dumpers and sold per cubic foot (CFT). But unless you measure the truck tub yourself, you could be losing 100–200 CFT per delivery, costing you thousands of rupees.
Common Construction Materials Delivered by Dumpers
Sand (Ravi, Chenab, Lawrencepur)
Crush (various sizes)
Bajri & Bajjar
Bricks (bulk loads)
Stone Dust
Filling Sand
Ghassu (clay-rich soil)
Most suppliers commit to delivering 800 CFT per truck, but without proper verification, you may receive significantly less.
Understanding Truck Dimensions: Why It Matters
In regions like Taxila, Kacha More, Hasnabdal, and Lawrencepur, the typical dumper tub dimensions are:
Dimension Range
Length 17' to 19'
Width 7' to 7'5"
Height/Depth 5" to 6"
Height is the most manipulated dimension. Drivers often reduce it to 4.5" or 5" while claiming 6", leading to massive under-delivery.
📏 How to Convert Inches to Decimal Feet
Volume is calculated in feet, not inches. So you must convert inches to decimal feet before calculating.
Inches Decimal Feet
1" 0.083
2" 0.167
3" 0.25
4" 0.333
5" 0.417
6" 0.5
7" 0.583
8" 0.667
9" 0.75
10" 0.833
11" 0.917
12" 1.0
Formula: Inches ÷ 12 = Decimal Feet
Example: 5 inches ÷ 12 = 0.417 feet
Truck Volume Calculator
Use this method to estimate the volume of any truck tub:
Length: 18 ft
Width: 7 ft + 6 in = 7.5 ft
Height: 5 in = 0.417 ft
Volume = Length × Width × Height
Volume = 18 × 7.5 × 0.417 = 56.18 CFT
Result: This truck carries only 56.18 CFT of material—not 800 CFT!
Real-World Loss Examples
If you paid for 800 CFT of material but received only 700 CFT, here’s what you lose:
Quantity Lost Price per CFT Total Loss
100 CFT Rs 70 Rs 7,000
100 CFT Rs 85 Rs 8,500
100 CFT Rs 105 Rs 10,500
Over 10 trucks, that’s a loss of Rs 70,000 to Rs 105,000.
Common Scams by Drivers & Roadside Vendors
Under-Delivery: Manipulating tub height to reduce volume
Offloading: Selling 100–200 CFT to roadside stores before delivery
Material Mixing: Combining inferior material to offer lower prices
Intimidation: Quarreling or misbehaving when caught
How to Protect Yourself?
✅ Measure every truck with a tape
✅ Convert inches to decimal feet
✅ Take photos before unloading
✅ Buy directly from crushing plants or verified suppliers
📍 Why Direct Purchase Is Safer
Buying directly from a crushing plant or verified supplier ensures:
✅ Accurate quantity
✅ Consistent quality
✅ Transparent pricing
✅ Professional behavior
Roadside vendors often mix inferior material and shortchange quantity to offer suspiciously low prices.
Don’t let fraud eat into your budget or compromise your structure. Whether you're building a home, school, or commercial plaza:
✅ Measure every truck
✅ Verify every delivery
✅ Buy from trusted suppliers
Need help sourcing verified material?
Contact a trusted supplier in your area or visit your nearest crushing plant for direct rates and guaranteed quantity.
Final Thoughts: Build Smart, Not Cheap
Construction is a long-term investment. Saving Rs 10,000 today by buying from a roadside vendor could cost you Rs 1 million in repairs later.
So:
✅ Measure every truck
✅ Convert inches to decimal
✅ Use the calculator
✅ Buy from trusted suppliers
Because in construction, precision is protection.
