Greetings, how are you steemit friends? Hopefully healthy always and still spirit. My discussion is still about the world of construction, daily and frequent contact.

In this discussion I will talk about barbed wire, barbed wire is often used as a temporary fence, either for home or on the construction area of work, hopefully, the discussion today useful.
It's good we know in advance what it is barbed wire.


BARBED WIRE


Before the barbed wire fence was used, the whole area of the settlements was left open by the locals, so it was not uncommon for the livestock to destroy the fields belonging to the people, but there were also those that fenced them with wood and the branches of the trees though ineffective.

Until after 1868 when a man named Michail Kelly invented the earliest technique of how to make barbed wire in modern by twisting two wires together, in 1874 Joseph F. Glidden received a patent for improving Louis Jannin's design from France. [source]

Although barbed wire has been mass-produced, there are still many people who make their own by modeling existing models, estimating more than 2,000 wire models have been created. [source]

Barbed wire made of galvanized type, the use of galvanized due to cheap and more durable.

After passing time evolved, eventually barbed wire proved itself in various types of wars, such as World War I, and several other large-scale wars, the use of wire is thought to slow down the pace and attack of the enemy infantry forces.

Actually, barbed wire is a wire created from long galvanized wire twist and has a wire-shaped wire at a certain distance, this barbed wire is usually stretched to fence a certain area to keep humans and animals from entering the area. [source]

Currently, barbed wire serves as part of construction material especially fences and is used as a barrier or security of buildings, agricultural land, construction work areas and others.

What if you want to make a fence of barbed wire, how much labor and materials are needed?


CALCULATION OF LABOR AND MATERIAL REQUIREMENTS


As mentioned above that in certain construction work the barbed wire fence is used to protect the work area, this safeguard intends that construction work is not disrupted due to external factors.

If the area to be fenced has a size of 12x15 m and requires a barbed wire fence with a height of 1.8m then how much labor and materials are needed?
Answer
Is known.

InformationAmount
Length12 m
Wide15 m

So to complete this calculation, you must determine the extent of the fence plan.
Around the fence.

InformationAmount
Length + length + width + width12 + 12 + 15 + 15
Total length15 m1
Total length x height15.00 x 1.80
Total area97.20 m2

In accordance with technical analysis of Indonesian National Standard [source] then to complete 1 m2 of barbed wire fence is required
Labor

InformationAmount
Workers0.200 Persons per day
Carpenter0.300 Persons per day
Foreman0.020 Person per day
Overseer0.020 Person per day

Material

InformationAmount
Dolken wood Diameter 8-10 cm long 4 m1,000 stems
Portland Cement2,000 Kg
Barbed Wire25.00 m1
Concrete Sand0.005 m3
Stone size 10-15 cm0.009 m3
Nail 2 "-5"0.060 Kg

Then to complete 97.20 m2 of barbed wire work is required
Labor

ItemsInformationAmount
Workers0.200 Persons per day x 97.20 m219,440 Persons per day
Carpenter0.300 Person per day x 97.20 m229,160 Persons per day
Foreman0.020 Person per day x 97.20 m21.944 Persons per day
Overseer0.020 Person per day x 97.20 m21.944 Persons per day

Material

ItemsInformationAmount
Dolken wood Diameter 8-10 cm long 4 m1,000 bars x 97.20 m297200 Stems
Portland Cement2,000 Kg x 97.20 m2994,400 Kg
Barbed Wire25.00 m1 x 97.20 m22430.000 m1
Concrete Sand0.005 m3 x 97.20 m20.486 m3
Stone Size 10-15 cm0.009 m3 x 97.20 m20.875 m3
Nail 2 "-5"0.060 Kg x 97.20 m25,832 Kg

CONCLUSION


Barbed wire has long been exploited by humans for more than a century, barbed wire is commonly used as a fence that serves as a barrier, barrier, and inhibitor.

Barbed wire is used because it is durable and cheap and easy to work even by untrained workforce though.
To complete the construction of a fence with a size of 12x15 m and a height of 1.8 m plan fence is required.
Labor

ItemsAmount
Workers19,440 Persons per day
Carpenter29,160 Persons per day
Foreman1.944 Persons per day
Overseer1.944 Persons per day

Material

ItemsAmount
Dolken wood Diameter 8-10 cm long 4 m97200 Stems
Portland Cement994,400 Kg
Wire rope2430.000 m1
Concrete Sand0.486 m3
Stone size 10-15 cm0.875 m3
Nail 2 "-5"5,832 Kg

This calculation is an example and can be used by anyone, this calculation is in accordance with the technical analysis of Indonesian National Standard and can be developed in accordance with the needs of the field.

This discussion is in accordance with my study at the University of Malikussaleh, Aceh that utilizing barbed wire as a temporary fence can be done as an alternative


This is the only thing I can write on this occasion, over all the mistakes and lack of unintentional writing as a servant of God, I apologize.
