Enter dimensions in m :. At the preparation stage, the most important is to evaluate correctly the amount of the worked out soil. The complete assessment includes the digging of the pit and transportation of the excavated earth. Transportation of the earth is an additional expenditure. To avoid any unexpected and undesirable expenses, all of them should be previously discussed and agreed with the contractor. If you prefer to dig a pit or a trench for drainage by hand you will certainly get more accurate work and the pit or trench will most likely have the sizes you planned.
This approach is relevant when the volume of the soil is not large and there is available manpower. The biggest advantage of this method is reduced expenditures, as you do not pay for the rent of the excavator or a backhoe, or any other special machinery. In the process, you can easily control the geometry and parameters of the future trench of the basement. When the planned volume of the soil to be removed from the construction pit is much bigger, it is more reasonable to dig by the backhoe to save the time and increase the effectiveness.
In any case, it is your choice. If you plan to go deeper or there is loose ground in the area where you plan the basement, your primary task is to ensure the security. It is better to do the walls of the trench with some minor slopes to stop any possible soil slipping. This online trench excavation calculator will be of great help to you. After all I got a blog from where I can truly obtain helpful facts concerning my study aand knowledge.

In some separate cases, a man can make choice in favor of various DIY solutions. Therefore, there is no need to highlight the importance of the project preparation process, correct drawings, and necessary estimation of the construction materials amount needed to realize the project.
It also seems worthwhile to do the estimation of the preliminary cost of the project before you break in. When developing a project, it seems reasonably critical to take into account some peculiarities like the constructional features of a building, engineering aspects, climate conditions, soil type, and so on.
Note that even minor mistake in the structure could be crucial. Luckily, there is no ground to be despaired. Even if you do not know all construction aspects, do not remember algebraic formulas or have no skills in their application, you always can go for the construction estimating software. The one can be easily found on our website. It can be used to do necessary calculations for purposes of a house construction, estimation of liquid volume, a roof area, estimation of construction materials amount needed.
You only have to take a measurement tape and ensure accurate and precise measurements. It will be also in service of you, if you are far from design matters. First, in the left column, there are main parameters specified and empty boxes given, where you have to enter your measurements data or information of prices. Important parameters are shown on drawings, and it gives you better understanding what figures are required and why. Then a window with computed results and dynamic drawings will appear in the middle of the screen.
The data of the results received and drawings will strictly correspond with the data you have just entered. Any change in values of parameters will automatically lead to the change of the drawings.
You will also get an explanatory note with static drawings having included the data about variables and the information to your further reference. There are two other functions provided by the present estimating tools.
You can print an existing project or save it for the next use. The building calculators estimate amount of materials and total cost of construction in most of the cases. Therefore, the complicated calculation of the lumber amount, pouring the foundation, heat insulation of building constructions, roofing work, fencing, estimation of the needed quantity of the concrete, reinforcement steel and other materials has become a simple and clear process.
If you have house building in mind simply use our apps to get costs estimation. The online program can compute preliminary expenses. The only you have to do is just to enter the price data in the corresponding boxes where they are. Thus, beside the drawings and basic data, you obtain the information about the approximate cost of construction materials and works.Measurements for volume are nothing more than applying basic distance and elevation measurements to determine the locations and elevations of points where the volume is to be determined.
It usually is not practical to take the time to collect data everywhere there is a slight change in elevation. Therefore, it must be understood that volume calculations do not give exact answers. Typically, approximations must be made and averages determined.
The field engineer will analyze the data and make decisions that result in the best estimate of the volume. The key to volume calculation is the determination of area. Most volume calculation formulas contain within them the formula for an area, which is simply multiplied by the height to determine the volume.
For instance, the area of a circle is pi times the radius squared. The volume of a cylinder is the area of the circle times the height of the cylinder. If an area can be determined, it is generally easy to determine the volume. Approximation is possible by plotting the figure to scale on cross-sectional paper and counting the squares.
Each square represents x number of square feet. Incomplete squares along the edges of the cross section are visually combined and averaged. The electromechanical digital planimeter is a quick method of determining the area of irregularly shaped figures.
The irregular shape is drawn to scale and the planimeter is used to trace the outline of the shape. Inputting a scale factor into the planimeter results in a digital readout of the area. Although a shape at first may seem irregular, it is often possible to break it into smaller regular shapes such as squares, rectangles, triangles, trapezoids, etc. This method may be cumbersome because of all the shapes that may need to be calculated.
If cross-sectional field data are available, use of this data is the recommended method of calculating volume. Once understood, this process is fast and the most accurate way of determining area. Cross-section data collected on a project represent elevation and location information for points on the ground.
These points can be used as coordinates to determine area. In road construction the shape of the ground must be changed to remove the ups and downs of the hills and valleys for the planned roadway. Often mountains of dirt must be moved to create a gentle grade for the roadway.
Payment for the removal and placement of dirt is typically on a unit cost basis. That is, the contractor will be paid per cubic yard of soil and will receive a separate price per cubic yard of rock.
It can be seen that accurate determination of the volume moved is critical to the owner and to the contractor. Each wants an accurate volume so payment for the work is correct. For road projects, cross sections of the ground elevations are measured at the beginning of the project, during the project, and at the end of the project. Comparisons between final cross sections and original cross sections are used to determine the volume moved.
Areas of the cross sections are most easily determined by using the elevations of the points and their locations from the centerline coordinates. The average end area method uses the end areas of adjacent stations along a route and averages them. Refer to fig This average is then multiplied by the distance between the two end areas to obtain the volume between them.
In formula form the process is as follows:. Dividing cubic feet by 27 converts to cubic yards. A method known as borrow-pit leveling can be used effectively to determine volume on building projects. A grid is established by the field engineer and elevations on the grid points are determined both before the excavation begins and when the work is complete.
The borrow-pit method uses a grid and the average depth of the excavation to determine the volume. Before the excavating begins the field engineer creates a grid over the entire area where the excavation is to occur.Construction excavation estimating and material takeoffs for contractors in the civil construction industry.

Learn Basic Formulas for Construction Estimating Are you exploring construction estimating as a possible career option?
Length — length is a simple formula used to determine the overall length of a specific condition related to a construction or remodeling project. Length is calculated by adding together the conditions that are similar on a potential project.
This is an addition formula. An example of this would be the installation of a fence line in a fencing project or the total length of electrical wiring needed in a tenant fit-out. Count — there are specific details which are calculated by counting. Counts are addition formulas and consist of adding together counts of specific details in a construction or remodeling project. An example of this would be the total faucets in a new home construction project or the total outlets in a wiring project.
Area — area calculations are used to determine the overall area to be covered by a certain process or material.
Area calculations are completed by multiplying length x width. Examples of the uses of area calculations include total area of roof covering for a roofing project or surface area for painting. Volume — volume calculations are used to determine the overall volume of a specific area that either needs to be filled or removed as part of a construction or remodeling activity.
Volume calculations are completed by multiplying length x width x height. Examples of this type of calculation include calculating the total amount of insulation needed to fill a cavity at a certain depth or an amount of fill needed to back fill during an excavation project.
Be square or Repair The calculation is based on the Pythagorean Theorem. Reduced to simple construction terms, it says that the foundation length squared plus the foundation width squared equals the foundation diagonal distance opposite corner to opposite corner squared. Verification is true in that 9 plus 16 is 25, of which the square root is 5. While protractors and T-Squares are very useful, the longer the distance for the measurement, the more accurate it is.
If you don't want to actually measure but can determine by a sting, both diagonals must be equal for a squared foundation. Just a fraction of a degree deviation from 90 degrees, over 20 feet or more, is a substantial error in causing walls to not be straight or square. A little extra effort in the initial stages yields a much more professional structure in the end.
This calculator is capable of use in the American system of feet and inches, and the metric system of meters. Select the American or Metric number system first. In the feet and inches mode American systementer your value of feet indicated as Feet, then the inches, if there are any, in the box indicated as Inches. If you have a fraction of an inch, you may enter it. Keep in mind that this is a decimal fraction; for example.
If you are uncertain as to the conversion, you may use our conversion tables for precision up to 64ths of an inch in decimal. If you already know the conversion of inches to a decimal, you may just enter it as feet. For example, you could enter 5 feet 6 inches as 5 in the feet box and 6 in the inches box, or just 5.
In the metric mode, only the first box on length and width is used; the system and calculator accept decimals. The answer is returned in feet, inches and construction fractions to 64ths in the American mode while the Metric mode returns meters and decimal values.
