Advice 1: How to calculate the amount of work

Job is to perform any actions aimed at the development and benefit of civilization. If we talk about the construction, for the proper organization of production is necessary to calculate the volume of work. That later will be incorporated in the final cost to the consumer. How do you do it?
How to calculate the amount of work
Instruction
1
Calculate the volume of works in construction. Today it is the largest amount. Review of project materials and place them in a convenient order for quick search. Divide the documentation into groups separately for underground and surface.
2
Calculate the volumes of work in a specific order: first count for openings in the outer walls, then to internal, then the work of the walls, the Foundation, any earthworks, floors, all ceilings, roof, staircases, balconies, various overhangs and porch. Proceed to the estimates of works internal and external decoration.
3
Use the specifications on the various materials used: concrete, wood, electrical, etc. in Other words, determine the rate of flow in appropriate units: cubic metres, square, linear, etc.
4
Calculate each of the works on the basis of the market value of one unit. For example, painting one square meter or strip per meter of cable. Consider the imposition of double and triple layers when working with finishing materials.
5
Calculate the volume of construction works by using special computer programs, for example, CADWizard that clearly and accurately make an estimate. Select a drawing, select it and the program will count the entire amount of work in this area. Set real scale, putting only the value of one element of the drawing, for example, walls.
6
Calculate the amount of mechanical work not related to construction. Here, everything is easier. Select the basis for any piece of work (volume). Take it as a unit, for example, loading and unloading of one machine, the number pasted up leaflets, the production of one part, etc. Guide the count of such units, where the work is completely done.
7
Determine the amount of mental work. First, clearly set goals, as detailed as possible. Then at the end of the allotted time, go through the points whose objectives are fulfilled. Determine the percentage amount of work performed to the task. Please note that some items may be more labor-intensive, and therefore require more time.

Advice 2 : How to calculate the volume of soil

Any kind of construction works is preceded by certain calculations. In the preparation of future building foundations, equipment pits, etc. must first calculate the volume of soil. From the correctness of calculations depends on the effectiveness of the backfill.
How to calculate the volume of soil
You will need
  • -dimensions of the pit
  • paper
  • -handle
  • calculator
  • -site plan with slopes
Instruction
1
Inspect the plot develop the soil and subject to irregularities and their sizes. Minor irregularities will not have a material impact on the result of calculations, but at the same time, the inspection will allow to determine the percentage of error. The calculation of the volume of soil is to determine the volumes of various geometric figures.
2
Determine the length of the sides at the surface of excavation, using the formula:A1 = A+B1 2НТ = +2НТ,where A and b is the length of the sides at the base of the pit;H – depth of excavation;the T – ratio slope
3
Take the dimensions of the pit and determine the amount of soil according to the following formula:V = H / 6 [(2A + A1)B + (2А1 + A)B1], where h is the depth of the pit;and – the length of the sides at the base of the pit;A1 and B1 – the length of the sides on the surface of the pit.
4
Determine the volume of the underground part of the structure using formulas from algebra course. Then, calculate the volume of backfill sinuses of the pit. It is equal to the difference between volume of excavation and volume of the underground part of the building. The accuracy of this calculation depends on the correctness of the produced measurements of height, width and depth of the underground part of the future facility.
5
After all the calculations are performed and verified, you can begin excavation. It is necessary to break the area of the upper and lower contours of the pit. The correctness of the planned development is checked by the sight of the poles exhibited along the lines of the future of the pit. For competent design of the slope requires the use of special templates and other professional fixtures.
Note
During the development of pits it is periodically necessary to control measurements, which will help to make a diagram of the pit. On the basis of this scheme is actually produced, the volume of earthworks, as well as the act of the executed works.
Useful advice
The volume of exploited surfaces in most cases is measured by the cubic yards of soil. But when planning or seal surfaces with a unit volume of soil can be square meters.
