### The cost of fixing interlocking paver blocks./ Rate analysis of paver block flooring.

Let us calculate the cost of fixing an interlocking paver block for the below-given drawing.

Given data:

Flooring area = 20 ft. × 18 ft.

Sand bed thickness = 2" = 0.166 ft.

Cement mortar thickness = 3" = 0.25 ft.

Cement mortar depth = 4.5" = 0.375 ft.

A. Material calculation:

1. Paver blocks:

The number of paver blocks required = 1044 nos.

To observe the above-given calculation of paver blocks, go through the articleðŸ‘‡

2. Sand:

The volume of the sand bed

= length × breadth × thickness

= 20 ft. × 18 ft. × (2 ÷ 12 ) ft.

= 60 cu ft.

3. Cement mortar:

= [(flooring periphery)  × depth × thickness]

= [(2nos. × 18 ft. + 2nos. × 20 ft.) × 0.375 ft. × 0.25 ft.]

= [( 36 ft. + 40 ft.) × 0.375 ft. × 0.25 ft.]

= [ 76 ft. × 0.375 ft. × 0.25 ft.]

= 7.125 cu ft.

Let us make the cement mortar in a 1:4 ratio.

Cement required /cu ft. of mortar =0.217 bags.

Sand required/ cu ft. of mortar   = 1.064 cu ft.

Note:  The above data is extracted from my article ðŸ‘‡

Calculating the quantity of materials in 1 cum. & 1cuft. of plastering mortar in different mix ratios.

Cement required for preparing the mortar

= total mortar vol. in cu ft.× cement / cu ft.

= 7.125 cu ft. × 0.217 bags

= 1.55 bags.

Sand required for mortar

= total mortar vol. in cu ft.× sand / cu ft.

= 7.125 cu ft. × 1.064 cu ft.

= 8.19 cu ft.

So, the total vol. of the sand required for paver installation

= [for sand bed + for cement mortar]

= [60 cu ft. + 8.19 cu ft.]

= 68.19 cu ft.

B. Labor calculation:

The labor rate for the paver fixing inclusive of mechanical floor compaction ranges from INR 10/- to INR 16/- per sq ft.

Let us consider the average rate of INR 13/- for the calculation purpose.

The total cost of the labor

= total area × rate / sq ft.

= 360 sq ft. × 13/-

= INR 4680/-

Now, let us calculate the cost of fixing the interlocking paver blocks in a table format.

 Sl. no. Item. Qty. Rate. in INR. Unit. Cost in INR. 1. Paver block 1044 16/- Nos. 16,704.00 2. Cement 1.55 400/- Bag 620.00 3. Sand 68.19 60/- Cu ft 4091.40 4. Curing Lump-sum 200.00 5. Miscellaneous Lump-sum 150.00 6. The material cost = 21,765.40 7. Add 5% wastage = 1,088.27 8. Total material cost = 22,853.67 9. Labour cost = 4680.00 10. The total cost of paver block flooring = 27,533.67

Note: To get accurate results, insert your regional market rate of materials & labor, in the above table.

Before fixing or selecting the paver blocks for installation, go through the articlesðŸ‘‡

ðŸ‘€. Classification of paver blocks. / What are the different types of paver blocks?

1.  The cost of paver flooring / sq ft.

= [The total cost of paver installation ÷ total flooring area]

= [INR 27,533.67/-  ÷ 360 sq ft.]

= INR 76.48 / sq ft.

2. The cost of paver flooring / sq m.

= [the cost/ sq ft. × 10.764]

(As 1sq m. = 10.764 sq ft.)

= [ 76.48 × 10.764]

= INR 823.23 / sq m.
