How to calculate building materials. The best construction programs How to calculate materials for a house

Construction work largely depends on the correct preliminary calculation of all necessary materials. Since a very large number of different types are used in this area, it is not possible to immediately come to the store and say: give me this or that, so that there is enough.

Before purchasing materials on the website pyramida.kh.ua, you should first evaluate the entire scope of work and roughly estimate how much to buy. There are many rules on how to correctly count such purchases.

Let's start the calculations

Performing calculations is a fairly simple process, but there are certain rules you should know when doing them. Each type of material has its own specific technique, which is tailored to certain conditions.

Today, to facilitate such procedures, you can use special services on the Internet, where you just need to indicate your parameters and the calculator will give you the required amount.

But to understand how this procedure occurs, let’s consider the basic rules for calculating some building materials:

Concrete is always calculated according to the required volume. To do this, you first need to know this parameter. The volume itself is calculated based on the amount of crushed stone.
Putty. The consumption of this material varies, but in most cases it is indicated on the packaging. To find out the full volume of material required, multiply the working area by this parameter.

In construction, there are many different materials that are used as finishing. To find out the required quantity of some of them you need:

Tile. When calculating the number of pieces required, you first need to know the area (wall, floor). After this, you need to calculate the area of the material itself (the area of 1 tile) and then divide the total parameter by the last number found. To find out the exact quantity, you need to round the resulting parameter to the nearest upper number.
Wallpaper. Calculating the required number of such products is not difficult and roughly boils down to the previous technology, where you need to find out the total area, height of the walls, length and height of the walls. The height of the ceiling often plays a role, since the length of the roll is not always a multiple of a certain number of strips, which can lead to large residues.

When calculating all building materials, the entire procedure boils down to finding the required quantity and calculating them based on average use for a certain volume, area, etc.

In order to avoid unreasonable cost overruns in future construction, as well as to avoid a shortage of materials leading to a decrease in the strength of structures, it is recommended to use professional special estimates. The Osnova company offers site visitors and potential customers to use an online calculator to calculate the construction of a house, as well as professional services of estimators.

Features of the construction calculator

The calculator on the page of our website allows you to perform the following operations:

Calculation of materials for building a house. The main ones are taken into account (foundation, walls, roofing). Calculation of the cost of installing communication networks (water supply, sewerage, ventilation, etc.), as well as basic interior and facade finishing.
Calculation of the required dimensional parameters.
Coordination of raw material characteristics with SNiP parameters.

If desired, the customer will be able to contact the company’s specialists in St. Petersburg to order a full estimate for turnkey construction, where the materials desired for use in finishing or construction will be calculated. We work throughout the Leningrad region.

Methods for calculating estimates - determining construction volume

The methods for determining the full estimate are as follows:

Measuring the project area. Calculations are carried out according to an approved package of documents, which includes drawings and sketches of the future structure.
Calculations based on the area of the plot. A visit by a specialist to the site of future development will allow you to determine the approximate parameters of the property.

The error of the result is up to 15–20%. The methods are suitable for multi-story or commercial construction, where it is difficult to take into account all the nuances. For the construction of a private house, a method for determining the construction volume is suitable. This method of calculation is considered by experts to be more objective and complete and consists of an expert assessment of the cost of construction for each segment. Not only the cost of building materials is taken into account, but also the price of work

How to use the calculator

The Osnova online service will help you calculate an estimate for building a house yourself and free of charge. However, it should be understood that without experience and understanding of construction processes, the result will still have an error. The sample given by the site is only suitable for preliminary calculations to assess your own financial capabilities. So:

In the “Walls” column of the calculator, you need to select the desired construction materials - aerated concrete, frame or brick. The same applies to roofing and finishing materials.
They do the same with other columns - floors, engineering, finishing, double-glazed windows, etc.
The types of technologies used are selected.

If the desired materials and technologies for building a cottage are not on the list, it is recommended that you contact the consultants directly and order a full estimate for construction. It takes into account any “little things”.

The nuances of using an online calculator

Of course, it will not be possible to calculate the project thoroughly. Any virtual calculator has errors. In addition, during the construction process, nuances may arise - the customer will make adjustments, or other factors beyond the control of the parties will arise. However, they must be reduced to a minimum in order to ultimately obtain the optimal result.

Initial data

Step 1: The calculator is designed to calculate any types of building blocks. To begin, set the exact dimensions of the building block without taking into account the masonry joint.

Be careful here: set the length, width and height of the block in relation to how the block will lie in the masonry. Next, enter such building parameters as the height of the wall and the total length of the wall along the outer perimeter of the building. Then indicate how the blocks will be stacked. The thickness of future walls directly depends on these data. This can be a structure of half a block (the thickness of the wall will be equal to the width of the block) or a whole block (the thickness of the wall will be equal to the length of the block). Choose the installation method depending on the designed number of storeys of the building, the type of floors and other features of the structure.

Step 3: To make the calculation more accurate, it is necessary to take into account the thickness of the masonry joint, consisting of mortar, or glue and other materials. Sometimes the thickness of horizontal and vertical seams is different.

Step 4: To calculate the masonry mesh, you need to decide how many rows you will lay it in. You don’t have to enter data about it by leaving the “Ignore” option in the column. Or count it, indicating that it lies through the Nth number of rows.

Step 5: Block weight is an optional parameter. But if you want to calculate the approximate weight of the finished walls and the load from the walls on the foundation, then it is still advisable to indicate it.

Price is also an optional parameter. Specify it if you want to calculate the total cost of blocks. Step 6:

To take into account the gables of the building, as well as windows, doors and additional openings in the calculations, check the appropriate boxes and set the necessary parameters in the list that appears. Step 7:

After filling in all fields, click the "Calculate" button.

You can print the results obtained or send them by email.

For convenience, it is better to count the various elements of the building separately. For example, external walls and interior partitions may differ both in height and in the way the blocks are laid. In this case, perform two independent calculations.	Explanation of calculation results
Building perimeter	The sum of the lengths of all walls taken into account in the calculations
Total masonry area	The area of the outer side of the walls. Equals the area of the required insulation, if it is included in the project
Wall thickness	The thickness of the folded wall, taking into account the mortar joint(s). Minor deviations from the final result are allowed depending on the masonry method
Number of blocks	The total number of all blocks required to build walls according to the specified parameters
Total weight and volume of blocks	Net weight and volume of blocks (excluding mortar and masonry mesh). This information may be useful for choosing a delivery method.
Number of rows of blocks including seams	It is determined by the height of the walls, the size of the materials used and the thickness of the masonry mortar. Gables are not taken into account
Optimal wall height	The recommended height of a wall made of blocks, which, as a rule, should be a multiple of the height of the block itself along with the seam. You may agree with this recommendation - then recalculate by entering a new value for the height of the walls in the calculator
Quantity of masonry mesh	Required quantity of masonry mesh in meters. Used to reinforce masonry, increasing solidity and overall strength of the structure
Approximate weight of finished walls	Weight of finished walls, taking into account all building blocks and masonry mortar, but excluding the weight of insulation and cladding
Load without taking into account the weight of the roof and ceilings. This value is needed to select the strength characteristics of the foundation

Select total area

The total area according to SNiP is the sum of the areas of all floors of the house, calculated along the internal contour of the external walls (including stairs, internal walls and partitions).

The area of balconies, loggias, porches, terraces and verandas is calculated with reduction factors from 0.3 to 1. The area of the attic is calculated up to vertical walls 1.5 m high, with a roof slope of 30 degrees. Below 1.5 to 0.9 m with a coefficient of 0.7. Below 0.9 m is considered a blind zone.

If you have difficulty calculating the total area, contact our specialists. There is also an imperial method - add 20% to the “total area” indicated in the standard project. As practice shows, for a two-story house the error will be 3-5 m2.

Foundation

Choose a foundation

The foundation is the foundation of the house. His choice primarily depends not on personal preferences, but on the geological structure of the soil at the construction site and the selected design solutions for the future home.

The foundations we use with their design features ensure load-bearing capacity for any technology of walls, ceilings, roofs and facades we offer. However, weak soils or high groundwater levels may require adjustments to the type or design features of the foundation.

Select walls

1. Aerated concrete blocks
Aerated concrete and gas silicate blocks (not to be confused with foam concrete) are manufactured in a factory with strength gained in autoclave ovens. The blocks have an ideal geometry, which allows them to be laid on thin-seam glue with the absence of cold bridges. Aerated concrete blocks with a density of 400 and 500 kg/m3 allow you to build houses of up to 3 full floors without the use of reinforcing monolithic frames. A block thickness of 400 mm is sufficient for construction in the Moscow region using modern heating technology.
2. Large format ceramic blocks
Large-format ceramic blocks (warm ceramics) replaced piece solid bricks. Sawdust is added to the clay and when fired, it burns out leaving small closed pores, due to which the blocks have very good thermal performance indicators. To preserve heat in the masonry, the blocks are laid on a special heat-insulating mortar with perlite, and thanks to the tongue-and-groove system, they can do without filling the vertical joints with mortar. A thickness of 440 mm is sufficient for the Moscow region.
3. Monolithic (fixed formwork Plastbau)
Swiss Plastbau technology is a monolithic construction technology using permanent formwork made of expanded polystyrene. Wall panels are completely manufactured in the factory, including the reinforcement frame, and delivered to the site cut to fit a specific house project. Factory production allows you to obtain the ideal geometry of wall panels, which only need to be mounted and concrete added. The outer layer of insulation is 100 mm, and the inner layer is 50 mm. Such insulation is not only sufficient, but also exceeds the requirements for the Moscow region, i.e. This is already an energy efficient technology.
4. Monolithic (permanent Velox formwork)
The Austrian Velox technology is a monolithic construction technology using permanent formwork made from chip-cement slabs. The slabs are manufactured in a factory in standard sizes 500x2000x35 mm; the outer layer uses 150 mm thick polystyrene foam insulation, which exceeds modern heating engineering requirements for the Moscow region. The slabs are easily installed on site, additionally reinforced and filled with concrete. In the built box of the house, the effect of a wooden house is felt, thanks to the smell of wood.
5. Monolithic (fixed formwork Durisol)
The Austrian Durisol technology is a monolithic construction technology using permanent formwork made from wood-chip cement blocks. The blocks are manufactured in a factory; the external blocks use 150 mm thick polystyrene foam insulation, which exceeds modern heating engineering requirements for the Moscow region. The blocks are easily installed on site, additionally reinforced and filled with concrete. In the built box of the house, the effect of a wooden house is felt, thanks to the smell of wood.
6. Expanded clay concrete blocks
Expanded clay concrete multi-slotted blocks around the perimeter of all load-bearing walls of the house. Non-load-bearing partitions made of gypsum tongue-and-groove slabs.

Walls are what, as a rule, everyone calls a house built from. “What is your house made of? Brick, what about yours? And mine is made of aerated concrete.”

Of course, the house consists not only of walls, but the customer’s choice is primarily based on their choice.

All wall technologies we use comply with current heating engineering standards in accordance with SNiP for the Moscow region. There are also technologies for increased energy saving, mainly using permanent formwork.

And of course, each technology provides sufficient load-bearing capacity to build a house up to 3 floors inclusive.

Floors

Select floors

Floors, the design of which was developed by our company, allows spans of up to 6-6.5 m to be covered. As a rule, in country houses, spans range from 3 to 6 m. For larger spans, additional reinforcement and strengthening of structures will be required.

We use only modern monolithic or precast monolithic reinforced concrete floors and practically do not work with floors made of wooden beams or prefabricated reinforced concrete hollow slabs.

All types of floors we use provide sufficient load-bearing capacity, fire resistance and sound insulation.

Select roofing

The roof is an important component of the constructive solution of the future home. Not only the appearance, but also the protection of the building from precipitation depends on its choice.

The entire roof structure is made of wood impregnated with fire and bioprotective compounds. The rafter structure is designed for any type of roofing.

The roofing itself can be chosen based purely on personal preference. Of course, you should pay attention to the service life of the roof. We use roofing materials designed for a service life of 20 years.

Standard equipment "warm circuit"

Select facade

The facade is the first thing that any person pays attention to when looking at a house. One glance is enough to tell whether he likes the house or not.

The choice of facade finishing depends solely on the personal preferences and financial capabilities of the customer. But regardless of this, the facade, in the solutions we have chosen, will provide protection for load-bearing structures from the effects of weather conditions.

The fundamental difference in the finishing materials of the facade is whether it is masonry or adhesive material. For example, facing brick is a masonry material; it rests directly on the foundation or console. Decorative plaster or stone is a material adhesive to load-bearing walls that transfers the load to the foundation through the load-bearing walls.

Select windows

Windows are an important component of a country house. Natural insolation of the premises occurs through them.

Windows must be of high quality, because... up to 30% of heat loss in the entire house goes through them. For example, the average thermal resistance of an external wall is 3-3.5 m2C/W, and that of windows is 0.6-0.8 m2C/W, i.e. 5 times more heat is lost through 1 m2 of glazing surface than through a wall.

This should be taken into account when choosing a project with floor-length panoramic windows; an in-floor convector should be installed under each window.

The best way to quickly estimate costs

Before you begin the pleasant and at the same time exciting procedure of building a future family nest, you need to conduct a financial analysis of the issue and clearly define the acceptable level of expenses for creating a residential building. If you have already decided on building materials, then an approximate online calculation of the cost of construction can be made directly on the company’s website. An intelligent calculator will allow you to create a preliminary estimate online, while it will take into account the area of the house, the type of foundation, the material of the walls and roof.

In addition, you can choose one of two options for finishing the facade, installing heating, electrical, water supply systems, and add to the estimate the costs of additional insulation and autonomous sewerage. The cost calculator for building a country house will take into account all your wishes and display the approximate cost. Of course, the geolocation of the site, the season of work and the complexity of the project will adjust its cost. Therefore, we recommend contacting the company manager to clarify the estimate.
