1. The volume of the dismantled building is determined in "Air" or in the geometry of the building:

House length X House width X Height(from the lowest point of the foundation to the ridge of the roof).

2. We calculate the real volume of construction waste prepared for removal:

V debris = V buildings in the air: K loosening

Loosening K = 2.0 - 3.0--- an empirical coefficient that takes into account all the individual coefficients of loosening of the generated construction waste.

To loosening = 2.0 - it has been experimentally established that the real volume of waste (taking into account the furnaces, old furniture and other garbage) is obtained using such a value

3. Calculate the Weight of the garbage to be removed.

P weight pin. Garbage = V garbage in solid x Mob.

Where Mob. = 1600 kg / m3---volumetric mass of construction waste received during disassembly.

The volumetric mass of construction waste should be taken as averaged according to the following standards:
- when disassembling concrete structures- 2400 kg / m3;
- when disassembling reinforced concrete structures- 2500 kg / m3;
- when dismantling structures made of brick, stone, plastering and facing tiles- 1800 kg / m3;
- when dismantling wooden and frame-filling structures - 600 kg / m3;
- when performing other dismantling works (except for dismantling metal structures and engineering and technological equipment) - 1200 kg / m3.
Note:
- bulk masses of debris from dismantling building structures are given from taking them into account in the dense body of structures;
- the mass of disassembled metal structures and engineering and technological equipment is taken according to design data.

Those. we have calculated the Weight of the removed waste in tons.

4. Further, depending on The weight and volume of garbage to be removed, we determine the number of containers or dump trucks required to remove garbage from the site for disposal. We take as a basis the VOLUME of the garbage to be removed.

Usually light bulky waste is removed in containers.

Heavy waste is removed by heavy-duty dump trucks (brick and concrete battle, soil). Special equipment is used for loading, because the dump truck cannot be loaded manually.

In our work, we use containers with a volume of 27 m3 (carrying capacity 12 tons) and dump trucks with a body volume of 18-20 m3 and a carrying capacity of up to 30 tons.

We calculate the number of containers / dump trucks as follows:

K =V debris / 27 m3 (or 20 m3 for dump trucks)

The cost of a container (27 m3) in Moscow at the end of December 2014 averaged 9,500 rubles (in the region of 10,000-11,000). The cost of the dump truck Moscow / region is 8000/10000, respectively.

We carry out dismantling works: scrapping, demolition, dismantling, buildings and structures, foundations, country houses, dachas, trade pavilions, mini-markets, shops, stalls, dismantling of walls, partitions, screeds, ceilings, any metal structures, floors, parquet, tiles, laminate, drywall, plumbing cabins.

We provide consultations on the dismantling of buildings and structures, country houses, demolition of any structures and disassembly of any structures, we will make a preliminary estimate for services for the demolition of buildings and structures.

Natalia Prokhorova from the Pskov region asks:

Acquired an old household with a very littered area. I want to get rid of unnecessary things and old buildings. In this regard, the question arises, how is the volume of garbage to be removed calculated?

The expert answers:

The price for garbage collection depends on a number of factors, the accounting of which will make it possible to produce correct calculation financial costs, the need to attract certain types and number of units of special equipment.

Calculation of the volume and mass of construction waste

• Calculate the size of the building by multiplying the measurements of the height, width, length with each other.
• The resulting number is divided by the coefficient of loosening, which is a number of 2.0-3.0.
• To calculate the mass of litter, the formula allows: multiply the amount of waste by the indicator Mob.

Indicator Mob. - the average number of the volumetric mass of residues formed during dismantling works. This number depends on the type of material:

• concrete - 2400 kg / m 3;
• reinforced concrete - 2500 kg / m 3;
• facing tiles, stone, brick - 1800 kg / m 3;
• frame structures, wood - 600 kg / m 3.

Other dismantling works, the exception of which is the dismantling of metal structures and equipment, are calculated individually, in accordance with the design data, and amount to an average of 1200 kg / m 3.

Calculation of service costs

To determine the level of financial costs, in addition to the amount of garbage, it is necessary to find out what kind of special equipment will be needed to eliminate construction litter. If the waste is light but takes up large area, you need a container. This category of materials includes wood, timber, logs. For litter, consisting of soil, concrete and brick debris, a closable bunker is required, designed to transport heavy loads.

To calculate the size of a container or bunker, the attraction of which will be advisable, the following algorithm is used: the volume of garbage is divided by the size of the container (8, 20, 27, 30, 32). If the total is over 4, a larger container should be chosen for significant savings.

Factors influencing the cost of disposal of construction waste

The total cost of services for the removal of litter is more or less influenced by the following factors:

• type of movement of construction waste - vertical or horizontal;
• the distance from the container to the place of dismantling work - it is not always possible to drive close to the object;
• additional packaging of construction waste in various containers;
• the number of workers involved in the removal;
• turnaround time.

If you are planning to demolish your house, you should clearly understand the need to remove the remaining construction waste after the demolition. And these works need to be planned and included in the calculations when ordering work to dismantle a house. Indeed, often, the cost of removal and disposal work exceeds the cost of the demolition work itself.

How to understand how much garbage will need to be removed after the demolition of your building and how to calculate the cost of garbage removal during dismantling. We will reveal a few secrets in this article.

Firstly, we will immediately make a reservation that such a thing as an accurate calculation of the amount of garbage during the demolition of large multi-storey buildings is feasible only for a trained engineer. The error in such a matter can be the greater, the less experienced the specialist.

There are too many factors to consider. Here's just a part:

The nature of the debris (building materials);

Dismantling and grinding technique;

Loading method;

Remoteness of the disposal site;

Complexity of loading operations;

The need for reporting on disposal;

The volume of the container (body);

Geographic location object (metropolis, city, countryside etc.).

It is important to understand one not unimportant detail: do not think that in the calculations you will be able to multiply all the geometric dimensions of the house parts, the length, the height of each of the walls, floors, roof area and multiplying all this by the thickness of these parts to get the exact volume of garbage to be removed. The fact is that when loading in the body (container), no matter how hard you try, there will be voids, because during demolition the parts will not have the correct geometric shapes... With this method of calculation, it will be necessary, taking into account the method of dismantling, loading, the type of material of the house, to multiply the resulting volume by 1.5, or even 2.5! This is the so-called direct opening factor. This method of calculation does not suit us, because we will have to sit down to construction manuals, what coefficient should we take into account. Entrust this work to professionals.

There are many known cases when, having no experience in demolition, starting the calculations, they make mistakes in the smaller direction. It is unpleasant when you have to take out much more than expected. But the opposite situation can also be - when the contractor overestimates the volume, and therefore the cost. Important not to miss here this moment and, if possible, control.

Now let's give a simple example of how, without all these intricacies, to understand how much construction waste a particular contractor will take out and whether he is not cheating in the calculations.

In addition to the geometric dimensions of the specified building (area on the ground, height in the ridge), only one number is needed. Let's call it the inverse loosening coefficient, it is equal to 2.65.This is its average value for low-rise buildings, when taking into account the building material, it may not change significantly up or down. But it is this number that will be enough to calculate the approximate volume of debris taken out during the demolition of a low-rise private house. The number that is deduced by experts empirically.

Consider an example with country house measuring 6 by 6 meters. The height of the building from the ground to the ridge is 7 meters. (It is in the ridge, because this is how the building volume of the building is calculated. If the roof is flat, then the height is calculated to top corner building)

We calculate the building volume of the building:

6x6x7 = 252 cubic meters.

Divide by the inverse loosening factor 2, 65:

252 / 2.65 = 95 cubic meters

95 m3: this is the approximate amount of construction waste that will need to be removed when this building is demolished.

The volume is calculated taking into account the underground part of the foundation (if there is no basement). This is how it works magic number.

Do not forget that the cost of removing the same amount of construction waste in different regions may be very different. Also, depending on the complexity of the object, the cost of loading work may differ. And of course, in the construction market, as in other markets, the wholesale rule applies, the larger the volume, the lower the unit cost.

2. We calculate the real volume of construction waste prepared for removal:

V debris = V buildings in the air: K loosening

The volumetric mass of construction waste should be taken as averaged according to the following standards: - when dismantling concrete structures - 2400 kg / m3; - when dismantling reinforced concrete structures - 2500 kg / m3; - when dismantling structures made of brick, stone, plastering and facing tiles - 1800 kg / m3; - when dismantling wooden and frame-filling structures - 600 kg / m3; - when performing other dismantling works (except for dismantling metal structures and engineering and technological equipment) - 1200 kg / m3. Note: - the volumetric masses of construction waste from dismantling of building structures are given from their account in a dense body of structures;

Usually light bulky waste is removed in containers.

Heavy waste is removed by heavy-duty dump trucks (brick and concrete battle, soil). Special equipment is used for loading, because the dump truck cannot be loaded manually.

In our work, we use containers with a volume of 27 m3 (carrying capacity 12 tons) and dump trucks with a body volume of 18-20 m3 and a carrying capacity of up to 30 tons.

We calculate the number of containers / dump trucks as follows:

K = V garbage / 27 m3 (or 20 m3 for dump trucks)

The cost of a container (27 m3) in Moscow at the end of December 2014 averaged 9,500 rubles (in the region of 10,000-11,000). The cost of the dump truck Moscow / region is 8000/10000, respectively.

Calculation of the cost of removal of construction waste

You can calculate the real cost of disposal of construction waste using the following method:

1. The volume of the dismantled building is determined in "Air" or in the geometry of the building:

House length X House width X Height (from the bottom of the foundation to the ridge of the roof).

2.Calculate the real volume of construction waste prepared for removal (in solid):

V debris in solid = V building in air: K loosening

K loosening = 2.0 - 3.0 --- an empirical coefficient that takes into account all the individual coefficients of loosening of the resulting construction waste.

To loosening = 2.0 - it has been experimentally established that the real volume of garbage (taking into account stoves, old furniture and other garbage) is obtained when using this value

3. Calculate the Weight of the garbage to be removed.

P weight pin. Garbage = V garbage in solid x Mob.

Where Mob. = 1600 kg / m3 --- volumetric mass of construction waste received during disassembly.

The volumetric mass of construction waste should be taken as averaged according to the following standards: - when dismantling concrete structures - 2400 kg / m3; - when dismantling reinforced concrete structures - 2500 kg / m3; - when dismantling structures made of brick, stone, plastering and facing tiles - 1800 kg / m3; - when dismantling wooden and frame-filling structures - 600 kg / m3; - when performing other dismantling works (except for dismantling metal structures and engineering and technological equipment) - 1200 kg / m3. Note: - volumetric masses of construction waste from disassembly of building structures are given from their account in the dense body of structures;

The mass of disassembled metal structures and engineering and technological equipment is taken according to design data.

Those. we have calculated the Weight of the removed waste in tons.

4. Further, depending on the Weight and volume of garbage to be removed, we determine the number of containers or dump trucks required to remove garbage from the site for disposal. We take as a basis the VOLUME of the garbage to be removed.

Usually, light bulky waste (logs, timber can only be taken out in containers) is taken out in containers.

Heavy waste is removed by heavy-duty dump trucks (brick and concrete battle, soil)

In our work, we use containers with a volume of 27 m3 (carrying capacity 10 tons) and dump trucks with a body volume of V = 20 m3 and a carrying capacity of 20 tons.

We calculate the number of containers as follows:

K cont. = Vdust / 27 m3 (or 20 m3)

The cost of a container (27 m3) in Chelyabinsk at the end of December 2013 averaged 9,500 rubles (in the region of 10,000-11,000). The cost of the dump truck Chelyabinsk / region is 6000/8000, respectively.

We carry out dismantling works: scrapping, demolition, dismantling, buildings and structures, foundations, country houses, summer cottages, trade pavilions, mini markets, shops, stalls, dismantling of walls, partitions, screeds, ceilings, any metal structures, floors, parquet, tiles , laminate, drywall, plumbing cabins.

Calculation of the coefficient of soil loosening

• 1 Types
• 2 Properties
• 3 How to calculate the conduct necessary work

With some construction works the soil is being developed for laying the foundation. For planning work related to the excavation and removal of land, some features should be taken into account: loosening, moisture, density.

The table below of the soil loosening factor will help you determine the increase in soil volume when it is removed from the excavation.

Views

• Rock, stone, rock and cemented formations - development is possible only with the use of crushing or using explosion technology.
• Clay, sand, mixed types rocks - sampling is done manually or mechanically using bulldozers, excavators or other specialized equipment.

Properties

• Loosening - increasing the volume of soil during excavation and development.
• Moisture is the ratio of the mass of water contained in the earth to the mass of solid particles. Determined as a percentage: the soil is considered dry at a moisture content of less than 5%, above 30% - wet, in the range from 5 to 30% - normal moisture. The more moist the composition, the more laborious the process of its extraction, the exception is clay (the drier - the more difficult it is to develop, too wet - becomes viscous, sticky).
• Density - the mass of 1 m3 of soil in a dense (natural) state. The densest and heaviest rocks, the lightest are sandy, sandy loam soil.
• Cohesion - the value of resistance to shear, sandy and sandy loam soils have an indicator - 3-50 kPa, clay, loam - 5-200 kPa.

Based building codes and rules (SNIP), the soil loosening factor (initial), the density indicator in accordance with the category, are given in the table:

After analyzing the table, we can say that the initial coefficient of soil loosening is directly proportional to the range of density, in other words, than the denser and heavier soil in natural conditions, the greater its volume during development.

There are also calculations of the coefficient of residual loosening of the soil, the result determines how much the soil succumbs to sediment when caking, in contact with water or compaction. In construction, these calculations have great value to quantify necessary material, and also they are taken into account when storing, utilizing land.

How to calculate the required work

To calculate the necessary work, you should know the geometric dimensions of the planned pit. Next, multiply the initial loosening factor by the volume of the earth in its natural state.

As a result, you will receive the volume that will be removed from the construction pit. Now it is very easy to calculate the amount of land withdrawn for storage, loading, transportation for disposal.

Watch the video: TYPES OF SOIL. GEOLOGICAL ANALYSIS OF THE SITE

During construction and renovation works trash remains. Even more of it is formed during the demolition, dismantling or reconstruction of buildings. These residues are taken out and then disposed of. To minimize costs, it is necessary to correctly calculate the volume and mass of waste.

For example, having calculated the weight of construction waste in 1m3 during dismantling, you can accurately order the carrying capacity of the machine, calculate the number of flights.

After dismantling buildings, materials of different characteristics remain. It can be paper, wood, concrete, or broken brick. The density is different for each type, and the costs for the export of a ton of brick will differ from the costs for the export of concrete. And since the costs of removal are included in the estimate documentation, it is important to accurately calculate the costs of these services. To do this, use the table, which indicates the volumetric and specific gravity by type of waste.

Specific weight of construction waste

The ratio of mass to volume occupied is called specific gravity. Formula for calculation:

Where m is the mass of residues (kg);

V is the volume of waste (m3).

Volumetric weight of waste from construction for estimates

V estimate documentation indicate the costs of removal, loading of residues formed during dismantling, waste from construction and repair work. When the costs are included, they are guided by the established prices, volumetric weight, the remoteness of the landfill.

There are standards that indicate the average volumetric weight of residues after disassembly. Estimated values ​​for estimates for demolition of structures:

• concrete - 2400 kg / m3;
• reinforced concrete - 2500 kg / m3;
• from brick, stone, plastering, facing tiles -1800 kg / m3;
• wooden, frame-filling-600 kg / m3;
• others (except for metal structures, equipment) -1200 kg / m3;
• metal structures, equipment - design data.

In this case, the average volumetric weight for estimates is taken in the "dense body" of structures.

Conversion of construction waste from m3 to tons

Waste generated as a result of demolition is mainly counted in cubic meters. meters, and the cost of removal, loading is calculated per ton. To include the cost of transportation in the estimate, the values ​​are converted from 1m3 to tons.

To do this, you can use the data of the averaged bulk density. If you need to know how many tons will weigh 3m3 brickwork, its average value (1800 kg / m3) must be multiplied by the volume (3m3).

1800 × 3 = 5400 kg = 5.4 tons.

When there is no data on the average volumetric mass, it is possible to calculate the tonnage of waste, knowing the volume, the density of these residues.

Density of construction waste

Construction waste includes residues from various materials... These materials have their own density. This is important to consider when:

• building logistic routes;
• the choice of the carrying capacity of the car for the disposal of waste;
• determination of the number, type of containers.

For loose dismantling residues, (according to SNiP), take into account the bulk density.

Bulk density = mass of loose waste divided by volume.

This takes into account not only the volume of the material, but also the space between it. That's why bulk density less than usual.

Density different types construction waste

Weight to volume ratio

Calculated values ​​are used to find out the ratio of waste (m and V) after disassembly. The tables indicate the volumetric, specific gravity of the exported material. Knowing them, it is easy to convert a ton of waste into m3 and vice versa.

Calculation methods

Still on preparatory stage the amount of waste is calculated. For this, the following algorithm is applied.

1. The volume of the object (in a dense body) is calculated. This takes into account the foundation, dimensions window openings, roof.
2. The calculated value is increased by 2 (loosening factor), and the actual volume of debris is obtained.
3. Find the mass of waste from the site by multiplying the actual volume by the density of the material.
4. Determine how to dispose of waste. For one type, the number of containers is calculated, for others - the carrying capacity of the machines.

Mass of a cubic meter of construction waste

To find out how many cubic meters are weights, use the average density. The value indicates the mass of waste of a given volume. For example, the mass of a cubic meter of mixed waste generated during repairs is 160 kg (0.16 tons), and a cubic meter of exactly the same waste from demolition will already be 1600 kg (1.6 tons). Since the average density of these materials is 0.16 t / m3 during repair, and 1.6 t / m3 during demolition (disassembly). In the same way, you can find out the mass of a cubic meter of sand, gravel, insulation.

If there is no data on the average density, then to convert cubic meters to tons, it is enough to multiply the volume by the density.

How to count construction waste from demolition of buildings?

To find out how much construction waste is formed after the demolition of the object, the density of the material included in the residues is determined. For this, use tables of material density, or use general calculated values.

Then the specific gravity or mass of the cubic meter is calculated. To determine the cost of delivery to the burial site, cubic meters are converted into tons. Calculated by the type of construction waste, taking into account the data on the volumetric specific gravity.

Demolition and dismantling of buildings leads to the formation a large number waste that needs to be removed in a timely manner. In order to manage time and transport in the most profitable way, it is necessary to calculate the volume and weight of the cargo for export. You can turn to specialists for calculations, or you can carry them out yourself.

Different types of waste also have different densities (mass to volume ratio). So, for example, the density polyurethane foam much less concrete density, that is, from two containers of the same volume, one of which is filled with concrete and the other with foam, the container with concrete will be heavier.

Important! The carrying capacity of any vehicle is limited, as is the volume of containers, which means that the higher the accuracy of calculating the weight and volume of the transported cargo, the higher the likelihood of saving time and money.

Knowing the density of the garbage is necessary to calculate its volume or mass. These data are needed to calculate logistic schemes: what capacity of vehicles will be used and how many cars (or flights for one car) will be needed, how much containers will be used.

For the convenience of calculations, the general averaged values ​​of the density are taken for different types designs:

• concrete - 2.4 t / m 3;
• reinforced concrete - 2.5 t / m 3;
• fragments of brick and stone, tiles, outdoor tiles, waste from removing plaster - 1.8 t / m 3;
• wood, frame structures with backfill - 600 kg / m 3;
• other construction waste (except for engineering and metal structures) - 1200 kg / m 3.

Important! The calculation of the mass and density of engineering and technological structures and metal products is calculated in accordance with the specified in project documentation information.

The above data refer to structures "in a dense body", that is, not disassembled. The actual density of the disassembled structures will differ (t / m 3):

• mixed waste (dismantling) - 1.6;
• mixed waste (repair) - 0.16;
• pieces of asbestos - 0.7;
• broken brick - 1.9;
• ceramic products - 1.7;
• sand - 1.65;
• asphalt road surface - 1,1;
• insulation ( mineral wool) - 0,2;
• steel products - 0.8;
• cast iron products - 0.9;
• plaster - 1.8;
• crushed stone - 2;
• fibreboard, chipboard - 0,65;
• wood (window and door frames, plinth, panels) - 0.6;
• linoleum (trim) - 1.8;
• roofing material - 0.6.

Mass of a cubic meter of construction waste

To find out the mass of a cubic meter of construction waste, you need to refer to the data on the average density values ​​presented above. Density shows how much mass a given volume has the right material... For construction waste "in general" the average density is 1.6 t / m 3 for mixed demolition waste, and 0.16 t / m 3 for repair waste. That is, one cubic meter of mixed waste from demolition will have a mass of 1.6 tons (1600 kg), and from repairs - 0.16 tons (160 kg). The mass per cubic meter of other types of waste can also be easily calculated using their corresponding density values.

It is worth referring to the same values ​​if the question arises "how to convert construction waste from cubic meters to tons?" Knowing the density and volume of a certain type of waste, you can calculate their mass by multiplying the density by the volume.

Specific weight of construction waste

Specific gravity is the ratio of weight to volume. Specific gravity is measured in N / m³ and is calculated by the formula mass (kg) * 9.8 m / s 2 / volume (m 2). For four cubic meters waste total weight in one ton, the specific gravity will be equal to:

1000 kg * 9.8 m / s 2 / 4m 3 = 2450 N / m³

Note! V Everyday life for us there is no difference between weight and mass, we are used to the question "what is your weight?", but when calculating it is important to remember that weight and mass are different physical quantities... Mass is measured in kilograms (kg) and weight in Newtons (N)

Other units of measurement are also used to indicate specific gravity:

• SGS system - dyne / cm 3;
• SI system - N / m 3;
• MKSS system - kg / m 3.

To convert N / m 3 to other units, you can use the ratio:
1 N / m 3 = 0.102 kg / m 3 = 0.1 dyne / cm 3.

Important! Despite the fact that the values ​​of density and specific gravity in some cases may coincide, it must be remembered that the specific gravity is measured in N / m 3, and the density - in kg / m 3.

How to count the construction waste of a building being dismantled

1. Determine the building volume of a building in a "dense body" by multiplying the length, width and height of the house, taking into account the foundation and roof.
2. Calculate the actual volume of waste for removal by multiplying the construction volume by the loosening factor equal to 2.0.
3. Calculate the mass of waste to be removed by multiplying the volume of a building in a "solid" body by the density of the type of waste.
4. Depending on the resulting mass, determine the number of containers or vehicles (based on their carrying capacity) that will be needed to remove waste for recycling.
