## Concrete Fence Construction Materials per 3-Meters

We have been asked several times about how much is a concrete masonry fence per unit meter. We hope this post will help non-technical people estimate their concrete fences. We tried to be as specific as we can so you will find this easy.

Figure 1 shows the typical fence we are going to estimate. The typical fence below is the basic concrete fence built in the Philippines. You can use this concrete fence plan to build your house fence.

Figure 2 above shows the 3D model of the fence. Note that we have put the names per structural member so you would know the what we are referring to later on.

The typical concrete fence details in the Philippines are modeled below

• Footing Details:

Concrete: 0.60m L x 0.60m W x 0.25m H

Reinforcing bars: 4pcs – 0.60m, 12mm Diameter Deformed bars for both horizontal and   longitudinal bars.

Total of 8pcs – 0.60m, 12mm Diameter Deformed Bars

• Column Details:

Concrete: 2.45m  H x 0.20m W x 0.20m L

Reinforcing bars:

1. Main Bars: 4pcs – 3.0m, 12mm Diameter Deformed bars
2. Ties: 18 pcs – 0.80m, 10mm Diameter Deformed Bars
• Wall Footing

Concrete: 0.20 H x 0.4m W x 2.8m L

Reinforcing Bars:

1. Longitudinal bars:3pcs – 2.8m, 12mm Diameter Deformed Bars
2. Horizontal bars: 10pcs – 0.4m, 10mm Diameter Deformed Bars
3. Vertical Dowels: 3pcs – 2.7m, 10mm Diameter Deformed Bars
• Masonry Wall

It’s hard to really explain how the numbers were computed. Anyhow, here is the summary of the materials for this masonry concrete fence plan. Note that only one set of column and footing were calculated in this example.

 Materials for Concrete Fence per 3-meters Structural Materials QTY Remarks Footing, Column and Wall Footing Cement 4.0 bag – 40kg Sand 0.2 cu.m. Gravel 0.4 cu.m. Gravel Bed 0.1 cu.m. 12mm Dia. 8.2 pcs – 6meter Length 10mm Dia. 4.4 pcs – 6meter Length Tie Wire #16 0.9 kg Masonry Wall Area (sq.m.) 6.3 150mm thk CHB 79.0 pcs Cement 9.5 bag Sand 0.3 cu.m. 10mm Reinforcing Steel 4.3 pcs – 6meter Length Tie Wire #16 0.3 kg Plastering Works (2 Faces) Area (sq.m.) 12.6 Cement 5.0 bag – 40kg Sand 0.3 cu.m.

 Materials Summary (per 3-meters concrete fence) Cement 18.5 bags of cement (40kg) Sand 0.8 cubic meter Gravel 0.5 cubic meter 150mm thk CHB 79.0 pieces 12mm Dia. Reinforcing Bars 8.2 pcs – 6m length 10mm Dia. Reinforcing Bars 8.7 pcs – 6m length Tie Wire #16 1.2 kg Plywood (may be used 3x) 0.8 pc – 4’x8′ coco lumber (may be used 3x) 22.0 linear meter Common Nail 0.5 kg

Again, only one set of column and footing were calculated.

The following are number of pieces per material used in the 3-meter fence above. No wastage factor were included. Normally, you would want to add 5%-10% of the materials above for the wastage factor.
