An example of an estimate for a private house. Drawing up estimates for the construction of a house from a bar. What does the customer receive before making a decision on construction in our company

Any construction after the creation of a house project should be based on estimate documentation. It is the estimate for, as well as at home from any other material, that allows you to prevent possible downtime in work, outlining the cost of all stages of installation, close to the final amount. In addition, the estimate documentation allows the developer to correctly distribute the stages of injecting funds into the construction site and precisely control the entire financial process. And in order to understand how to make an estimate correctly, we provide the material below.

Frequently asked questions related to the cost of a home construction plan

How much would it cost to build a house? Do you have a specific house plan? We want to help you stay on budget. We will help you calculate the cost of building a house. And if you'd like to make changes to keep your build costs down, our home modification service can help. Below are our most frequently asked Build Questions.

Home decoration costs

How can I order the cost of generating a report? First, you will need to select the plan of the house for which you want to get the cost for the report. Browse our house plans and find the one that interests you. You will be asked a few quick questions about your preferences and the location of your building, and then you can look online.

Items displayed in the estimate

To understand the principle of formation estimate documentation and see the example of the estimate proposed in the material, you need to understand from which points the document should be formed. Remember, if you miss one of the construction stages and do not include it in the calculations, you can get into an unpleasant situation, which is fraught with negative consequences for a half-built log frame.

Expense reports are usually published within 2 business days of placing your order. Where does the cost data come from? We calculate the cost of building a house based on what you tell us. Our numbers are not based on national averages and our reports are not "canned". Each estimate is made for the order of the house plan, the quality of construction and the zip code you choose.

What is included in the cost of creating a report? Estimated costs include factors for all materials, labor and equipment required to build a home in accordance with national building codes, as well as any known adjustments required for seismic, wind, frost and snow loading conditions. The total also includes permit costs, general overheads and profits, and any applicable sales tax for your region.

Important: it is always necessary to start drawing up an estimate by studying project documentation... Namely - the calculation of square meters of external and internal walls, as well as the area of the roof and foundation. These data will allow in the future to calculate the most accurate amount of required material, and, accordingly, the cost of purchasing it.
What does the customer receive before making a decision on construction in our company
It is assumed that you are building a house on a relatively flat or shallow lottery, and the estimated costs reflect this. In addition, some assumptions were made about the quality and quantity of specific building materials that are common to the type, style and size of the selected plan. Custom additions or changes cannot be reflected in this value if they go beyond the standard methods for this type of construction.

Costs are based on the completion and performance outlined in your chosen plan, and the actual construction of the home can increase or decrease these costs. Construction materials, labor and service data in our reports are very complete and include the following points. However, it is very important to understand that the quality of the design you choose can lead to a significant change in the report. It is important to check when preparing a report.

So, the estimate documentation for the construction of a house from a bar should include the following items:

The cost of purchasing all wall material, including fittings, fasteners (pins), insulation, etc. It is worth remembering that depending on the type of timber (planed, profiled, glued) the amount may vary. And the section of lumber plays an important role in obtaining the final amount.
The cost of installing the foundation and floor inside the house. It is worth noting here that most often the installation of the base takes 30% of the total amount of construction financing. Although a lightweight type of base can be arranged under a log frame, which will save some money.
Expenses for finishing material both outside the house (if it is necessary for a planed beam), and inside the cottage. For this, we will calculate the area of the walls of the building.

What are the standard materials adopted for the report? The number of stoves and air conditioners is determined by the total area of the house. Grungy framing: wooden frame used to build the structure of a house. This includes all walls, floor joists, and roof trusses. It also includes any plywood sheathing used on top of truss roofs and floor beams, as well as outside exterior walls. Also includes any insulation in walls and ceilings.

Wall material costs

Floor Covering: includes any material used to cover any floor in a home. It also includes any required material for floors and carpets. The standard ratio is 80% carpet to 20% vinyl tile, unless the plan indicates some other material such as stone or parquet is to be used.

The cost of roofing, which includes both roofing material and timber for rafters, battens, as well as insulation, waterproofing materials and all fasteners.
Also, the estimate should include the financing of the work of professionals, if it is planned to build not with your own hands, but with the help of invited craftsmen.

Tip: Maybe the specialists will not perform the entire scope of work, some specific task. In this case, it is better to immediately include the cost of work in the tedious cost item.
Exterior decoration: A decoration material that is added to the outside of the exterior walls of a house. This can include any combination of brick, stone, plaster, or siding. Appliances: Electrical appliances typically supplied by the builder when building a home. This usually includes assortment, dishwasher and garbage collection. If additional devices are selected in the system, such as refrigerators, freezers, microwaves and garbage compactors, these will also be included.

Communication costs
The material for the window frame varies depending on the size and quality of the house, from aluminum to high quality horizontal horizontal windows. The system does not currently use high energy or insulating windows in its calculations. Interior decoration: everything that covers the wood structure of the walls and ceilings, and brings the interior of the house into a finished state. This includes all sheets, drywall, and paint. Kitchen and bathroom cabinets are also included in this section. 100% paint is selected for all walls and ceilings.

Financing of all communications in the house, including plumbing, sewerage, electrical wiring, etc.

Important: when carrying out calculations, it is worth taking into account the design nuances of a log house, such as ledges, balconies, bay windows, roof slopes, etc. Also, the estimate includes the rental of special equipment, if it is required for installation work.
Roof covering: material that is installed on top of the sheet material above the roof trusses. These are usually some form of shingles, but can be metal panels, copper and gravel roofs. Electrical: all electrical parameters for the home. This includes rough wiring that is installed in front of any surface, all outlets and lights, and basic connections from the power source to the home.

Plumbing: all plumbing options for the home. This includes all rough plumbing installed prior to any trim, plumbing for the bathroom, kitchen and utility rooms, a water heater typical of the home, and a basic plumbing and sewer connection.

Advice: if the analysis and assessment of the soil on the site has not yet been carried out, then it is worth allocating funds for this stage of work.

Calculation principles for budgeting

To estimate documentation for the construction wooden house was complete, it is necessary to understand that the document is drawn up on the basis of the materials necessary for the construction. And the calculations themselves are carried out based on the following data:

Special Features: These options are selected by default based on the size and quality of the home. What is not included in the cost of creating a report? The site does not include an assembly cost report. Site preparation of any kind Removal of existing structures Lot purchase Site preparation Raketka Individual garages or other structures Landscape design... What are Other Duties and Taxes?

This estimated cost breakdown includes permit fees, overheads and profits, and other differences. fees. The permit cost is the amount added to the total construction costs to cover building permits, usually assessed by local governments for housing construction... The costs of issuing permits can be lower or higher than it depends on your local government's assessment.

The type of material used to build the walls;
Price per unit of its volume (packing / m3 / pallet, etc.);
The total amount for the entire required amount of material. Plus, it is advisable to add 5-10% to the possible price fluctuations upon purchase and to the stock of the material. It is also worth adding to this the costs of transporting goods to the construction site.

Calculation of the cost of the foundation

A fee is added to cover the cost of any work related to local interior design and structural engineering. To do this, add 3% to the total score. These fees may be lower or higher depending on the specific problem. Overhead costs are costs incurred by a builder or general contractor to run their business, but not related to any particular job. We add 10% to cover contractor overheads. Overhead costs can vary significantly from contractor to contractor.

Some examples of overhead costs are general and administrative expenses, office rent, utilities, office supplies, salaries for office staff, depreciation on office equipment, licenses, and advertising. Profit is formally defined as the excess of the selling price of goods by value. Profit is usually added to the cost of the construction work to enable the home builder to do the work to grow their company through reinvestment.

In order to understand how much will have to be spent on the installation of the foundation, it is necessary to calculate its parameters. So, let's imagine that we have cottage from a bar, the perimeter of which is 6x6 m. Taking into account the fact that a lightweight type of basis can be made under a log house, we have the following parameters:

Depth - 40 cm.
Width - 40 cm.
The total length along the outer walls is 24 meters. To the same indication we add the length of the foundation for the internal partitions. Here we take another 8 meters of total length as an indicator. In total, we have 32 meters of foundation 40 cm deep and 40 cm wide.
Now we multiply 32x0.4x0.4 = 5.12 m3. This will be the total volume of the shallow strip foundation under our building.
Next, you need to find out the cost of m3 of ready-made concrete mixture.

Important: Note that self-preparation of concrete in such quantities is difficult. And since it is necessary to fill the foundation in one stage, it is better to order a ready-made solution. Thus, the strength of the base will be undeniable, in contrast to the step-by-step self-pouring method.
The main sections of the estimate
We add 10% to cover the contractor's profit. Profits can vary significantly from contractor to contractor. How about different levels of material quality? So from the dream of a home, it finally becomes a reality: more space for the whole family and to meet the long-awaited living space. With our free construction cost calculator, you get the first overview of home construction costs, so you can count solidly from the start.

This will help you understand what your new building will cost.
To calculate the construction cost for your new building, you can enter the appropriate data in the input fields with a blue frame. In addition to house and land costs, all construction costs and external installation costs are also included. The Construction Cost Calculator then automatically calculates all contingencies and provides a first overview to help you plan your mortgage financing.

So, we multiply the cost of m3 of concrete by the obtained required volume. To this we add the possible costs of delivery and rental of special equipment. But it is quite possible that these items are already included in the price of the concrete mix.
Now the cost of the boards must be added to the cost of the foundation to create the formwork. Here it will be enough to calculate the total area of the formwork, as we know it, and multiply by its height. We get 12.8 m2. That is how many boards are required before the construction of the formwork. We multiply the volume by the price of m2.

Land Before the foundation for your home can be poured, you need the right land - and it has a price. Enter the total amount of living space, as well as the type of equipment and the number of floors to calculate. High-quality fittings are, for example, facades with natural stone panels, precious wood glass, intricate dowel coverings or high-quality floors. To determine the number of floors, the definition in force for your region in the Land Building Rules always applies. Example: According to the Mecklenburg-Vorpommern State Building, a full floor is granted if the top edge of the ceiling exceeds an average of more than 1.4 m above ground level. According to this building code, the cellar is not a full floor. However, according to Bavarian state building codes, a basement can also be considered a full floor. Home connection costs. In the case of construction connection costs, you enter all the details that are calculated for connection to individual power lines. If the fields are not suitable for construction, or the costs have not been corrected, you can also leave the individual fields blank. You can also proceed with the calculation later. Construction Costs There are fixed fields here that no longer need to be edited. This is because these partial costs can be calculated automatically from statutory or pre-established grounds. These include, for example, the basic income tax from the state and extraordinary expenses based on legal regulations... Other cost centers have already been entered as they are often fixed. If other prices have nevertheless been agreed, or if these costs are even completely lost, this can be corrected later in the form of a manual entry. Exterior installations This part of the building cost calculator is a cost that is highly individual and often the last touch on a home. For this reason, many builders neglect these costs in their initial planning. Outdoor structures include, for example, paths and driveways, terraces, or even slopes on slopes. These are often not small items within the construction costs and should be taken into account from the outset.

Just enter the price of the item you are interested in.

And, of course, the cost of reinforcement must be included in the foundation costs. In this case, you need to know that for a foundation width of up to 40 cm, reinforcement of four longitudinal rods is used. In this case, with a foundation length of more than three meters, it is necessary to use longitudinal reinforcement with a cross section of 12 mm. For transverse bridges, a rod with a cross section of 6-8 mm is used.
To calculate the amount of reinforcement needed, it is necessary to multiply the total length of our foundation by 4 (the number of longitudinal rods). In this case, the resulting value will be multiplied by another 10% in order to have a margin for joining the rods in knitting. In total, we get the total footage of longitudinal reinforcement with a cross section of 12 mm. The value is multiplied by the price of the material per volume. We calculate the transverse rods by dividing the length of the foundation by the spacing of the reinforcement in the binding. Then we multiply the resulting number by 2 (two rows of the location of the transverse bars).

Important: after calculating the cost of purchasing material for the foundation, it is necessary not to lose sight of the price of the work of the master who will knit the reinforcement.

We count the purchase of a bar

Before proceeding with the calculations, it is necessary to determine the type of timber for construction and its section. Thus, we find out the price of the material required for the construction of a house. Now you need to calculate the total volume of the timber in m3.

You need to calculate this way:

First, we calculate the total perimeter of the house. In our case, it is 24 meters (we count without internal partitions, since a beam of a smaller section will go to their device for subsequent finishing).
Now we multiply the perimeter by the height of the walls. Let's take 2.6 m as an example.Total we have 24x2.6 = 62.4 m2.
And then you need to multiply the resulting value by the thickness of one bar. In our case, it will be a bar with a section of 150x150 mm with a thickness of 15 cm. 62.4x0.15. In total, as a result, we get 9.36 m3 of timber required for the construction of all external walls.
Now you need to calculate the amount of timber in one m3. And since for each section of lumber its quantity in 1m3 differs, the calculations are performed by dividing the total timber required for the construction by the volume of one unit.
It remains to enter all the data obtained into the estimate table and multiply the result by the price of one timber or by the price of m3 of sawn timber. Do not forget to include pins and insulation in the cost of expenses.

Tip: the calculation of the costs of installing internal partitions is carried out according to the same principle.

Roofing costs

The construction of a house cannot be considered complete if the box does not have a roof. it Finishing work can be postponed indefinitely, and the installation of the roof for a wooden building must be carried out immediately after the forcing of the walls. Otherwise, the tree will get wet.

So, everything is extremely simple here:

We know the roof area from the project for the house. Based on the available data, you need to determine the total volume roofing material and multiply by the price per unit of its volume.
To the resulting amount we add the cost of insulation and waterproofing, the volume of which will also be equal to the area of the roof plus 10% of the margin for joints and overlaps.
Also, the cost of the timber for the rafters and the ridge should be added to the total amount. The amount of lumber is calculated by dividing the length of one roof plane by the pitch of the rafters. We get the number of rafters on one side of the roof. We multiply this number by two (two sides of the roof for a gable roof one-storey house 6x6 m).
Do not forget to take into account the costs of fasteners, accessories and payment for the work of the craftsmen, if any are involved.

Communication costs

This section of the estimate is one of the most difficult and painstaking. Here it is necessary to include the large name of the components and fittings. So, for a water supply system, it is worth considering the cost of such elements:

Digging a well or drilling a well;
Arrangement of the water intake point (purchase of concrete rings, etc.);
Digging a trench to bring the pipe to the house;
Laying of the entire water supply system (footage of pipes of the required section;
Taps, filters, mixers and water meters;
Pumping equipment for supplying water to the house;
Installation of a caisson or room for a pumping station;
Installation of all plumbing equipment (toilet, sink, bath, dishwasher, etc.).

Now, based on the length of the water supply system in the house, we calculate the costs of sewer communication, the pipes of which will be located parallel to the water main. But now the pipes will have different and larger sections. So, the estimate of the sewage system includes the cost of such elements:

Pipes in the required quantity in accordance with the project documentation;
All adapters, tees and fittings;
Work on digging a trench for the installation of an external sewage system (if workers are invited);
Thermal insulation of the external pipeline (consumables for this type of work);
Septic tank or biological storage device.

And of course, don't forget about the electrical wiring. The estimate includes the cost of the work of a professional who will perform the entire volume from the removal of electricity from the general line in the village to the installation of all sockets and power points in the house. In addition, the estimate documentation includes the cost of cables, wires, sockets, switches and other accessories.

Home decoration costs

It is important to know that home decoration can include the cost of all window and door blocks. And then the total amount of the selected finishing material is added to this amount. You just need to know its retail price. But in this part of the estimate, the amount can only be calculated in a very streamlined manner, since tastes and preferences may change over time, and the price of materials may decrease or increase. So here you can achieve accuracy with an error of 10-15%.

Important: having standard mathematical skills, you can independently calculate the approximate cost of a log house. But if you doubt the correctness of your actions and are afraid to make mistakes, then it is better to turn to professionals who will help you fully or partially understand the preparation of the estimate documentation.

Brick construction in Russia is confidently holding its positions. After all, this wall material is one of the best in terms of wear resistance, inertness to water and cold, aggressive media and combustion. In this case, the level of thermal conductivity brick block quite suits the modern developer. And therefore, in the material we will figure out how to correctly estimate the construction of a brick house.

It is worth remembering that the estimate documentation allows not only to determine the approximate amount of construction costs, but also to exercise control over the infusion of funds into the work. After all, it is not always advisable to stop at a certain stage of construction due to lack of money.

The main sections of the estimate

Any estimate documentation should be as detailed as possible in order to exclude possible incidents and downtime during the construction of a house. So, in the content of the estimate for brick house it is worth including such sections:

The cost of soil preparation work. If the site is not ready for construction, it will have to be cleared and the top fertile soil layer removed in order to save the land for planting garden crops or ornamental plants. This expense item includes the rental of special equipment, if the need arises.
The cost of building the foundation for the house. It is known that for a brick building you need to make a monolithic tape or slab foundation... And the higher the house is, the deeper and wider the base should be. So, for two-storey house it is better to make a slab foundation or de base more than a meter deep from bricks.
Financing the forcing of walls. This includes the cost of the wall material in the required volume and add to the amount the costs of the mortar and the possible work of specialists.
Ceiling device made of concrete slabs. As a rule, for these purposes, special equipment is rented, which will lift slab floors. This item of expenditure should not be forgotten in addition to the cost of the reinforced concrete products themselves.
The cost of installing the roof, including the price of roofing material, beams for rafters, boards for lathing and insulation with waterproofing. Also, do not forget about fittings and fasteners.
The cost of window and door blocks for the house, as well as their installation.
Financing the installation of all communications, such as water supply, sewerage, electricity.
Interior decoration. This expense item will help you deduce the total amount required for the installation of the building. And although this amount is approximate, it will still be close to the expected result.

Tip: don't forget to include in the estimate fare for the delivery of building materials, as well as spending on the work of invited craftsmen.

Calculations for the foundation

Foundation device - the main part of the construction

Since everything is clear with the points of the estimate for cleaning and preparing the site, and the calculations for the foundation and wall material more confused, then we will consider precisely these aspects of the estimate documentation. We will deduce the calculations using the example of a one-story brick house with sides of 10x10 m. Having understood the principles of performing mathematical operations, you will be able to independently make an estimate in the future for any other type of building.

So, the estimate for the foundation device should include the following items:

Digging a trench for a tape or slab. The latter option is especially relevant, because if you can still dig a trench yourself, at least somehow it is possible, then it will take a long time to dig a pit for a monolith. So it is better to use an excavator, which will have to be paid at the rate of rent / hour.
Then it is necessary to include the formwork device in the expense item. Moreover, both the performance of the work itself and the cost of the material that will be needed to fill the tape. An edged board is used as a material. To calculate its quantity, it is necessary to find out the length of the entire basis. And these are 4 walls 10 meters each, plus all the internal partitions. Let's imagine that the total length of the foundation inside the house is 18 meters. In total, we have (4x10) + 18 = 58 meters of formwork. Now you need to multiply by the height of the base to get the number of boards in m2. For the initial one, we take a foundation with a depth of 1 m and add to it the height of the basement 50 cm.Total, we have 1.5 meters of the height of the formwork. 58x1.5 = 87 m2. And now we multiply the value by 2, since the formwork consists of two walls. In total, we get 174 m2 of boards. But lumber is calculated in m3 or pieces. Therefore, the resulting number is multiplied by the thickness of the board, calculated in meters. And if the standard thickness of the board is 25-30 cm, then you need to multiply by 0.25-0.3 m. So, 174x0.25 = 43.5 m3 of the board is needed for the formwork. It remains to multiply the result obtained by the price of one m3 of board. And do not forget to include all fasteners in the estimate.
Now you need to calculate the amount of concrete or consumables for mixing it.

Important: taking into account the fact that it is better to pour the tape at a time in one approach, it is better to buy a ready-made concrete mixture, since it will not be possible to prepare such an amount of mixture with your own hands. And it is forbidden to fill the foundation of the tape type in stages by SNiP. Otherwise, the base will be shaky. Therefore, we will consider the estimate using the example of calculating the amount of concrete.

Everything is simple here, it is enough to multiply the total length of the foundation, its height and width. We already have a total length of 58 m. The height of the base together with the plinth is 1.5 m. And its width for laying in two bricks will be 60 cm (provided that the laying in two bricks is 51 cm thick). So, we multiply 58x1.5x0.60 = 52.2 m3. This is the volume of the ready-made concrete solution needed to fill the entire tape. Now we multiply the volume by the price of one m3 of ready-mixed concrete.

Rebar costs.

Important: SNiP regulates that with a foundation width of more than 40 cm, it is necessary to use reinforcement in six longitudinal rods. That is, three on top and three on the bottom with a step of 20 cm. Otherwise, the solidity and reliability of the base will be doubtful.

To simplify the task, you can use the online calculator on the construction portal. But if you gravitate towards mathematics, then we will count on our own. It is known that the tape is reinforced in two belts (lower and upper). In this case, the location of the vertical rods should be in increments of 50 cm. Knowing the total length of the foundation, we multiply the number by two (lower and upper belts). 58x2 = 116 m. And now we multiply this number by six (the number of longitudinal reinforcement strips in two belts. 116x6 = 696 m of longitudinal reinforcement with a cross section of 12 mm. Now we calculate the length of the rods for vertical knitting of belts. Taking into account that they need to be placed on a distance of 50 cm from each other, we divide the total length of the basis by 0.5 and get 58: 0.5 = 29 m. This is the footage of a vertical rod for one longitudinal knitting, and we have three of them. So, we multiply the number by three. 29x3 = 77 m. And it remains to multiply the resulting value by the height of the rod (1.4 m - the height of the foundation - 5 cm from the top and 5 cm from the bottom to the deepening of the reinforcement) .Total we have 77x1.4 = 107.8 m of the rod with a section of 6-8 mm ...

Important: it is advisable to add a coefficient of 0.2 to the stock of the rod to the volumes obtained. And now we multiply the received volumes by the cost per m2. We do not forget to include in the estimate the costs of delivery and the work of a professional who will knit the reinforcement.

Wall material costs

We decided that our exterior walls will be made of two bricks. Using the example of forcing the outer walls, we will consider how the calculation of the volume of the material is performed. And we already know that the thickness of a wall of two bricks will be 51 cm. The length of our walls is 10m and 10m. The height will be conditionally 2.5 m.In this case, we have 7 window openings with parameters 1.2x1.5 m and one door 1x2 m.

Important: calculations can be performed using the method of taking into account the thickness of the seams and without taking into account this parameter. In the first case, the volume of the brick can exceed the real one by 25-30%, but it can be used for a possible battle and laying of internal partitions. In the second case, the calculations will be more accurate, but another 10-15% will have to be added to a possible battle.

The first calculation method looks like this:

Determine the total length of the outer walls - 10x4 = 40 m;
We calculate the area of the walls, multiplying the length by the height - 40x2.5 = 100 m2;
We calculate the total area of all window and doorways- (1x2) + (1.2x1.5) x7 = 14.6 m2;
Now, from the total area of the walls, we subtract the area of the openings - 100-14.6 = 85.4 m2 clean brickwork along the outer wall.
Now we display the number of bricks in a square meter of masonry. To do this, we determine the area of its end: 0.12 * 0.065 = 0.0078. It remains to divide the resulting value by one: 1 / 0.0078 = 128. The result is multiplied by two (2 bricks masonry). As a result, we have 128 * 2 = 256 bricks per 1 sq. M.
It remains to multiply the volume of bricks in m2 by the number of m2 of masonry - 85.4x256 = 21,862.4 pieces.
The total is multiplied by the price of the brick, and the cost of delivery is added to the estimate.

The second calculation method looks like this:

Here, to complete the count, you will need to increase the estimated dimensions of the brick by 5 mm (standard thickness masonry joint). The calculations will look like this: (0.12 + 0.005) * (0.065 + 0.005) = 0.00875. That is, the number of bricks per m2 will be: 1 / 0.00875 * 2 = 229 pcs. It remains to multiply the masonry area by the number of blocks in m2 - 229 * 100.6 = 23037.4 pcs. And it is necessary to add to the quantity a stock in the range of 1500-2000 pieces. We have approximately 25 thousand pieces of blocks. We also multiply the total by the price.
It is worth noting that for the withdrawal of costs on the walls, the solution must also be taken into account. According to building codes, about 200 liters or 0.222 m3 are used per m2 of masonry in two bricks.

Important: Hollow brick will take up more cement, as its voids will be filled with mortar. And this means overspending of the mixture.

Roof estimate

It is easy to calculate the costs here. Knowing the parameters of the roof from the design documentation, we deduce the volume of the roofing material and multiply it by the price per unit volume. In the same way, we calculate the volume of waterproofing and insulation. The estimate includes lumber for the installation of rafters and battens, as well as all fasteners. The rental of special equipment for laying the ceiling and the cost of the work of the craftsmen should also be included in the documentation.

In total, we have a rough idea of how to plan the costs and costs of construction.
