Wall ceramic covering work is often found in toilets, operation / surgery and so on.
The use of ceramic on the wall is intended to prevent dirt / stains in the form of liquid or other does not stick to the wall and damage the wall.
As in the use of toilets intended for soap and water splashes are not absorbed by the walls, so does the operating / surgical room intended to avoid attaching dust to walls and damage operation / surgical equipment.
Ceramics derived from the Greek keramikos word meaning a form of clay through the burning process. [1]
At first ceramics only shaped pottery, tile, porcelain and so on so that the use of ceramic words on the floor and wall has not been so well known.
The floor tiles and walls are then developed made of clay and as a gloss coated with glazing, but there are two types of ceramics contained in the market are ceramic with glazing layer and porcelain tile (homogoneus tile). [2]
In the market we can find a variety of types and motives and sizes, each product offers their respective advantages, such as material that lasts cheap prices and so forth.[3]
Excess ceramic / tiles as wallcovering is. [4]
- Strong and durable.
- Not absorb water.
- Easy maintenance.
- Large selection of sizes, motifs and colors.
- Easy to find.
The shortage of ceramics / tiles as wallcovering is. [4]
- Brittle.
- The connection will affect the final result.
- Sometimes it is difficult for the same motif in use over the next few years.
Wall tiles is distinguished by floor tiles, in addition to price and size of wall thickness is also different. Wall tiles is relatively thinner than the floor tiles.
In accordance with its type, ceramics are divided into several qualities depending on precision and shine produced. [5]
Once we have a little knowledge about ceramics then it's time we make calculations and needs of labor and material on the wallcovering work.
In accordance with the picture below, how much labor and material needs to complete the work of wallcovering with wall tiles size 25 x 40 cm?
)use the app. autoCAD
)use the app. autoCAD )use the app. autoCADTo complete the calculation of the work then I will calculate the total area of wall tiles.
Is known :
| Items | Information | Amount |
|---|---|---|
| Area of area A | 1.37 x 1.60 | 2,192 m2 |
| Area of area B | 1.37 x 1.60 | 2,192 m2 |
| Area bisang C | 1.37 x 1.60 | 2,192 m2 |
| Area width D | 0.59 x 1.60 | 0.944 m2 |
| Area of A + B + C + D | 2,192 + 2,192 + 2,192 + 0,944 | 9,712 m2 |
I use technical analysis in accordance with Indonesian National Standard [6] to complete the calculation of labor and material requirements on wallcovering work.
To finish 1m2 wallcoverings using wall tiles the size of 25 x 40 cm is required.
Needed.
| Items | Amount |
|---|---|
| Wall tiles dim. 25x40cm | 1,060 m2 |
| Portland cement | 9,300 Kg |
| Sand plug | 0.180 m3 |
| Color cement | 1,940 Kg |
| Workers | 0.900 Person per day |
| Stonemason | 0.450 Person per day |
| Foreman | 0.045 Person per day |
| Overseer | 0.045 Person per day |
In accordance with the above coefficient then the calculation with the area of need is.
| Items | Information | Amount |
|---|---|---|
| Wall tiles dim. 25x40cm | 1,060 x 9,712 = 10,295 m2 | |
| Portland cement | 9,300 x 9,712 = 90,322 Kg | |
| Sand plug | 0.180 x 9,712 | 1,748 m3 |
| Color cement | 1,940 Kg x 9,712 m2 | 18,841 Kg |
| Workers | 0.900 Person per day x 9,712 | 8,741 Person |
| Stonemason | 0.450 Person per day x 9,712 m2 | 4,370 Person |
| Foreman | 0.045 Person per day x 9,712 m2 | 0.437 Person |
| Overseer | 0.045 Person per day x 9,712 m2 | 0.437 Person |
- Total number of wall tiles
Is known.
| Items | Information | Amount |
|---|---|---|
| Ceramic size | 25 x 40 cm | 0.10 m2 |
| Amount / m2 | 1.00 / 0.10 | 10.00 Units per meter |
| Needs x Units per meter | 10,295 x 10.00 | 102,947 Units / pieces |
Rounded 103 units / pieces, this rounding has taken into account the clipped and defective ceramic / tiles unit.
To finish the work of wallcovering with wall ceramic / tiles dim. 25 x 40 cm like the picture above is required.
| Items | Amount |
|---|---|
| Wall Ceramic/Tiles dim. 25x40cm | 103 Units / chips |
| Portland cement | 90.322 Kg |
| Sand plug | 01,748 m3 |
| Color cement | 18,841 Kg |
| Workers | 8,741 Person |
| Stonemason | 4,370 Person |
| Foreman | 0.437 Person |
| Overseer | 0.437 Person |
After the calculation of labor requirements and the material is completed is calculated then to determine the amount of price, you can directly make the multiplication of the price of labor or material in your respective place.
This calculation is only an example and can be used by anyone, this calculation is in accordance with technical analysis of Indonesian National Standard and can be developed in accordance with the needs of the field.
After this calculation is complete it is expected that young engineers to continue to develop knowledge for the realization of a better civilization.
this is all I can write on this occasion for all the mistakes and lack of writing as a servant of God, I apologize.
