How much labor and material needs for floor work?

kharrazi (63)in #engineering • 7 years ago (edited)

Greetings, how are you steemit friends? Wish you good health always. In the previous discussion we have calculated the needs of labor and materials on the work of mountain foundations, sloof reinforced concrete, brick walls, reinforced concrete floor plate and painting.

Our discussion today is the calculation of labor requirements and floor work materials, this flooring work includes backfill work, K-100 cast concrete, landfill sand and floor coating (ceramic size 40 x 40 cm).

At this early stage we should know in advance technical backfill work, landfill sand, K-100 cast concrete and floor coating.

a. Backfill work

^{Backfill work that has been done. The photo I ( @kharrazi ) took a few months ago on a construction project using a pocket camera}

The soil used must meet the technical specifications, the backfill compaction is done by means or manually, the backfill overlap is done by not accumulating in a particular field to facilitate the worker in the process of overlaying.

b. Landfill sand

The landfill sand in question is layered in layers and compacted manually or by means.

c. Concrete (K-100)

^{Workers are lining the K-100 concrete for floor-coating. The photo I ( @kharrazi ) took a few months ago on a construction project using a pocket camera}

The foundry work begins by mixing the material in accordance with the specification until it becomes homogeneous, after the concrete mixture is stirred, it is poured into a bucket or a stroller and overlaid on the floor surface, when casting needs to be compacted by pounding the surface with wood so that cast gravel can be mutually filling and solid, on the surface that has been considered flat need to be made rough with broom stick.

d. Floor coating (Ceramic size 40 x 40 cm)

^{Workers are installing floor linings with ceramic sizes 40x40 cm. The photo I ( @kharrazi ) took a few months ago on a construction project using a pocket camera}

Floor coating work that we will discuss is ceramic floor size 40 x 40 cm, this work started after the work of the cast floor is considered finished.

Ceramics will be lined with a layer of water mixed with cement, this mixture serves as a glue between the ceramic and the cast floor.

After the ceramic is dry and considered finished then the worker then insert ceramic gap with color cement so that ceramic not quickly damaged during expansion.

The use of ceramic floor is very common in Indonesia, ceramics have high flexibility and can be used in almost all rooms.

Another plus is, ceramic does not require polishing and has a low maintenance cost.

Currently ceramic is very easy to find on the market, various colors and textures we can choose to make ceramics cheap choice of users.

CALCULATION OF LABOR AND MATERIAL REQUIREMENTS

I use technical analysis in accordance with the Indonesian National Standard to determine the required labor and material requirements for floor work with an area of 4.00 M 2

a. Backfill work
To work on 1m3 backfill jobs is required:

Items	Amount
Worker	0.300 Person Per Day
Overseer	0.010 Person Per Day
Land	1,200 m3

To do backfill work with a volume of 0.88 m3 is required

Items	Information	Amount
Workers	0.300 Person Per Day x 0.88 m3	0.264 Person
Overseer	0.010 Person Per Day x 0.88 m3	0.009 Person
Ground	1,200 m3 x 0.88 m3	1.056 m3

c. Concrete Work K-100
To work on 1m3 of K-100 concrete work is required:

Items	Amount
Worker	1,200 Person Per Day
Stonemason	0,200 Person Per Day
Foreman	0.020 Person Per Day
Overseer	0.060 Person Per Day
Portland Cement	230,000 Kg
Concrete Sand	893,000 Kg
Gravel	1,027,000 Kg
Water	200,000 Liter

To do the work of K-100 concrete with a volume of 0.20 m3 is required

Items	Information	Amount
Worker	1,200 Person Per Day x 0.20 m3	0.240 Person
Stonemason	0,200 Person Per Day x 0.20 m3	0.040 Person
Foreman	0.020 Person Per Day x 0.20 m3	0.004 Person

The calculation of the need for floor work is just an example and can be used especially to young engineers and lay people, analysis of labor and material needs calculations on this work using the analysis of Indonesian National Standard, can be developed as needed.

This is all I can write right now, for all the lack of writing and as a servant of God I apologize.
