Construction attack on the construction of the house. An example of calculating the estimates on the construction of a house of foam concrete blocks. Total cost, rub

The fact that any business should be started with the calculations known to each person. Prepare to shove wallpaper in the house - count what costs will be needed on wallpaper, glue, putty, the work of the malaria. Want to build a table with your own hands - calculate the cost of boards, screws, plow glue.

During the construction of the house, it is necessary to take into account all the construction stages and costs for them. Such indicators are concentrated in the work project in the SPECIAL Documentation section.

How to make a estimate for the construction of the house without a loss and revision?

On how to make a estimate for the construction of the house, known to designers-estimates, prohibits, other categories of IER and builders. A certain idea of \u200b\u200bthis has ordinary people who are not related to construction work, but we have identified the construction of housing. Their desire is clear: they do not want to overpay the extra sums. If a person persistent and purposeful, he will not be difficult to fulfill the calculations. Samples of estimates for the construction of the house are widely represented on the Internet.

Estimated documentation is prepared on the basis of calculationsin which paragraphs with indicators are represented:

• ordinal number;
• the rooms of estimates and calculations;
• the name of the construction stage;
• estimated cost, which consists of the cost of carrying out construction and installation work, the use of materials, other expenses;
• total estimated cost.

Estimated calculations signed by the authority of the compiler and the customer are considered a monetary document that is the basis for the actual performance of work, participation in the tender, etc.

When drafting estimates for the construction of the house, all important and secondary positions take into account. Sometimes the customer seems to include this or that item of expenses is not at all necessary. But during the construction of "emergencies" unexpected expenses, unaccounted in the documentation costs. The customer understands this and lays 5-10% in the documentation for unforeseen overhead. These can be funds aimed at receiving tolerances from fire bodies, gas workers, electricians, waterways and other permits or other types of expenses.

As you can see, make an approximate estimate for the construction of the house is not very difficult, if you know the consumption of materials, regulatory prices and current prices. The article also shows a sample of estimates for a residential building from gas blocks (see Fig.).

Output

Each person may calculate construction costs. But experts perform it more qualified and competently. Sometimes they overestimate the amounts of separate items. In order to settle the indicators, the owners themselves can fulfill count or turn to the help of other organizations.

The construction of the house or building begins with the fulfillment of the calculation and compiling the estimates, taking into account the materials used, the work performed and the cost of renting special equipment. That is why in construction it is customary to use the estimation that clearly displays the financial costs of the construction of a particular object. Estimation is used for all types of buildings. In this article, we will tell you what is estimated at home and how it can be calculated, and how much it costs to calculate the estimation.

Composition of estimates for construction

Estimation for the construction of the house is the main document for specialists, without its presence, no firm-developer will carry out the construction of the structure. The main financial costs fall on the purchase of building materials and additional elements to them. Performing calculation of the estimate should consider such parameters as:

• the amount of planned work;
• used technology;
• construction time;
• the number of specialists in the project;
• the volume and timing of the financing of the object.

These criteria will allow the customer to monitor the timing of the building process, check out the individual types of work. The main task that the estimate of the construction of the house decides:

• compliance with a clear job schedule;
• the amount of financing during the period of work.

To fulfill the calculations, the Customer may apply to several firms at once, for this it is necessary to conclude an agreement to draw up a document. As a result, the estimate of the house compiled by different experts will be distinguished by the total cost, this comes from the fact that each company makes its suppliers of materials, professionals performing work. After reviewing several documents, you can compare and choose for yourself the most optimal option for money and without prejudice to the future design.

Be sure to launch small or unforeseen expenses of 15% of the total value of the object. It may be transportation costs, payment for obtaining various references related to construction.

Purchase of land and settlement

The cost of construction, as a rule, begin with inclusion in the consumable part of the value of the land plot. The land is purchased in several ways that are not contradictory to the law:

• redemption of the site for the former owner;
• redemption from state ownership;
• get a land plot available for free, subject to the presence of free land.

At the time of acquiring a land plot, be sure to make a contract, this document will help to avoid fraudulent operations and legally will protect you. The contract must contain:

• subject of the contract: the purpose of the site, its category and the total area;
• the price of a plot agreed by sellers by the buyer.
• When the transaction has already been carried out, the state registration of the transfer of property rights is performed. For this, the following documents are submitted to Justice:
• application registration;
• receipt of payment for registration of the site;
• purchase and sale agreement;
• passport and additional documents confirming personality;
• cadastral plan.

The entire package of documents is adopted by the relevant authority and the decision is made in the period established by the legislation, which is one month.

For information! When performing several building processes with different contractors, you need to perform the compilation of the estimate for construction work for each of their form.

The price of such a document may vary from 9 to 40 dollars, because The calculation depends on the number of positions in the document. The term for compiling documentation from 1 day, depending on urgency.

How to make a estimate

Calculation of future expenses for the construction of the work of specialists, but if you are confident in your abilities, you can create a estimate for construction and yourself. The photo shows an example of estimates for the construction of a skeleton house. The procedure for compiling a document:

• determine the number of materials;
• find the necessary technique;
• agree with specialists about construction.

When you already have a view from what a house will be built, as it will look, in which part of the site stand, what materials will be used, it will not be difficult to calculate the final amount. It is worth noting, on the Internet now a large number of construction forums, where you can download an empty blank of the estimate document or make it yourself in the office program.

So, how to make a estimate for the construction of a house from a tree? To compile estimates, costs are necessary:

• Decide with the sequence of action of actions, understand what works should be entrusted to building organizations, and what can be performed and yourself.
• The following is the calculation of the estimates, depends on the use of construction technologies. It is to determine the volume of building materials and structures, their use.
• When all this data is already there, you can find a company providing construction services, familiarize yourself with the rates, find out the cost of materials and work.
• Next, the component takes all the values \u200b\u200bobtained and transfers them to its table, where in the context of each type of work or products will be summed upwards.
• When all the data is filled in graphs: Name, cost of work, unit of measurement, you can perform a general summation of the project. For convenience, you can make a total digit into the right side of the table, for this you need to configure the formula. This calculation can be performed for the design of any material and project.

This method calculates the number of materials and the volume of work on all types of houses, regardless of which they are built.

Calculation of costs for foundation, roofing and finishing materials

Estimation for construction work must necessarily contain information about the foundation, roofing and finishing materials, these positions are the most expensive. In order to understand how to calculate the volume of material on the foundation of the house, you should multiply the perimeter, height and thickness of the foundation base. As a result, we will get the volume and find out the cost of 1 cu. m. Concrete and multiply it on the resulting value. The roofing material is to calculate very simply for this you need to take the total area of \u200b\u200bthe roof from the project to the house and the cost per 1 sq.m. Material, and then multiply them with each other. Calculation of the cost of finishing the most challenging task, for this it will be necessary to multiply the price of 1 sq.m. Each type of product.

We invite you to view the video where it is shown how to perform the calculation of the estimates

The choice of foam blocks for the construction of the house indicates a reasonable savings of the developer. To assess the benefits of such a solution, you should first calculate turnkey estimates. This will help to schedule future expenses and find out whether the accumulation of buildings in the family budget is enough. In addition, the detailed listing of materials gives an objective picture of the upcoming construction and suggests the way to saving funds without prejudice to the house.

Drawing up the estimates is made on the basis of the project of the house. As an example, for self-calculation of materials, we consider a small building from foam blocks on a tape base consisting of three rooms, a kitchen and a terrace.

Estimated on the foundation

Since foam concrete is a lightweight material, then when erecting a bath, summer kitchen or a small cottage, screw piles can be used. According to experts, for the construction of a house of 1-2-floors more suits the foundation of a ribbon type. It can be a monolithic or prefab, swallowed or lowered. Such a base for the house looks quite time consuming and costly, but it has a big plus. The ribbon foundation makes it possible to lay a basement or cellar under the residential building from foam block.

A monolithic base is well suited for the sample, complex in production and reliable in operation. Estimation for construction work will contain all the costs of its device.

1. For a plot with a non-empty soil, we choose a small-breeding foundation with a depth of 0.6 m. Trench you need to dig by 20 cm deeper - to make a sandy pillow.

For blocks of 600 × 300 × 200 mm, we set the width of the base in 0.5 m. The foundation for the house will be fill in the formwork, therefore its final height is 0.6 + 0.4 \u003d 1.0 m.

2. Determine the length of the tape:

• (8 × 2) + (6 × 2) \u003d 36 m, exterior walls;
• 8 + 6 \u003d 14 m, internal partitions;
• 4+ (1.3 × 2) \u003d 6.6 m, terrace.

The total length is 48.6 perm.

3. We calculate the volume of concrete required for the fill of the monolithic foundation: 48.6 (tape length) × 1.0 (height of the base) × 0.5 (base width) \u003d 24.3 m 3.

4. In a schedule for construction, we list the components necessary for the independent kneading (if you wish, you can order a finished solution of factory manufacture). Their number is determined based on the brand of concrete M300. 1 m 3 mixtures will need:

• 385 kg of cement M400;
• 1080 kg of gravel / rubble;
• 705 kg of sand of a large fraction;
• 200-220 l of water.

To find out how much each material is required, the standard bookmark parameters multiply on the volume of fill:

• 385 × 24.3 \u003d 9.367 tons cement;
• 1080 × 24.3 \u003d 26,244 T rubbank;
• 705 × 247.3 \u003d 17,132 tons;
• 540 liters (depends on the humidity of the components).

5. Calculate the amount of sand for dumbfoundation under the foundation of the house of foam blocks:

48.6 (Length of the tape) × 0.5 (width) × 0.2 (pillow thickness) \u003d 4.86 m 3. We round the result to 5 and a total of 17,132 + 5 \u003d 22,132 tons of sand.

6. When building a monolithic base, fittings are always necessary. For our sample, choose a frame of two longitudinal rows, 2 bar in each diameter of 12 mm. For transverse rows, fittings are required by a cross section of 10 mm. With a jumper step in 0.5 m, the transverse cut of the frame is 30 × 0.65 m, the length of the rods is 0.35 m (horizontal) and 0.7 m (vertical). Just one design (ring) You will need 0.35 × 2 + 0.7 × 2 \u003d 2.1 m. In addition, for jumpers for jumpers, you need to provide tires 3 × 4 \u003d 12 pcs. 1 m. Total 12 meters or 2 rods 6 m.

7. Determine the total number of reinforcement for the estimate for the construction of a house of foam concrete: 48.6 × 4 + 12 \u003d 206.4 m or 35 rods 6 m with a diameter of 12 mm.

8. Accelerate the number of rings for jumpers: 48.6 / 0.5 + 1 \u003d 98 kits or 35 bars 6 m.

9. For mating fittings, use soft steel wire at the rate of 0.5 m per connection. For jumpers will need 98 × 4 \u003d 392 pcs, for tires 12 × 4 \u003d 48 pcs, only 440 mating × 0.5 m \u003d 220 meters.

Estimation for foam concrete blocks for building a box

In the project of the house 6 × 8, we plan to masonry the bearing walls in half block. For the inner partitions, a quarter of a stone is sufficient.

• 0.06 m - spoon or side of the foam block (200 × 300 \u003d 60000 mm);
• 0.18 m - Square bed or base base (300 × 600 \u003d 180000 mm).

1. In the house of foam blocks, we choose the height of the wall 2.8 m. It will require 14 elements in half block. Taking into account the suture compounds (14 pcs. 0.5 cm), we obtain 2.87 m. In fact, the height of the walls indoors will be 2.6-2.7 m (reduction at the expense of the ceiling and screed).

(8 + 7.3 + 8 + 6 + 4 + 1.3) × 2.8 m \u003d 96.88 m 2 - Square of bearing walls.

For construction, it will take: 96.88 / 0.06 (s spoon) \u003d 1615 pcs of foam blocks in the shemna.

2. Determine the area of \u200b\u200bthe internal partitions: (8 + 3 + 3) × 2.8 m \u003d 39.2 m 2. For their construction, foam blocks are required in a quarter of the element: 39.2 / 0.18 (s bed) \u003d 218 pieces.

3. Total in the estimate of the construction indicate such a number of foam concrete blocks: 1615 + 218 \u003d 1833 pieces.

4. We figure out the volume of dry glue for seams in the bearing walls from the foam block. We have 14 horizontal (2.8 / 0.2 \u003d 14) and 58 vertical (34.6 / 0.6 \u003d 57.6 m) compounds with a thickness of 0.005 m.

• The total length of horizontal seams: 34.6 × 14 \u003d 484.4 m, the amount of glue for it: 484.4 × 0.3 × 0.005 \u003d 0.7266 m 3.
• The length of the vertical seams is 58 × 2.87 \u003d 166.64 m, respectively, glue will leave 166.64 × 0.3 × 0.005 \u003d 0.24969 m 3.

Total consumption is 0.7266 + 0.2499 \u003d 0.9765 m 3 or 1000 kg.

5. Calculate the glue for the construction of internal partitions with a total length of 14 m. We have 10 horizontal (2.8 / 0.3 \u003d 9.3) and 24 vertical (14 / 0.6 \u003d 23.4) seam.

The total length of the compounds: (14 × 10) + (24 × 2.8) \u003d 207.2 m.

The volume of glue for the inner walls: 207.2 × 0.2 × 0.005 \u003d 0.2072 m 3 or 270 kg.

6. General consumption of dry adhesive solution for the house of foam blocks: 1000 + 270 \u003d 1270 kg or 51 bag of 25 kg.

When drawing up the estimate to the roof is better to attract specialists. It is a complex design, with the construction of which it is difficult to cope on your own. The opinion of professionals will also be needed when calculating the cost of plumbing, insulation and facing at home.

Table of main construction costs

By connecting together all the costs of expenses, we get the estimate to build a turnkey foam block house.

If the construction work independently, then the greater accuracy in the calculations is not required. It is enough to take into account the main items of expenses and learn the rates acting in the region.

How to save on the construction of a house of foam concrete?

First of all, the budget will help the right choice of foam concrete blocks. In the cold regions, the main task of construction is to preserve heat in the house. For these purposes, foam blocks 600 × 300 × 200 mm are best suited. It is convenient to stack them in any way, varying the thickness of the house box to the desired size. The number of blocks will always be minimal and without excess costs.

To reduce the estimation of the construction of the cost of foam blocks and other materials, it is better to contact the manufacturer. Rates for wholesale parties can be reduced by 5-15%. Do not save, buying cheap foam concrete dubious quality for construction. Additional costs of correcting uneven walls of the house will block the difference and can even exceed the estimate.

The price of the finished concrete of the factory production looks more expensive to the improvised solution for the construction of the house. But the savings on the manual kneading can turn into large losses of working time and unnecessary labor costs.

Calculating the approximate cost of building a house of foam concrete, the bulk materials laying should always be done more. When sand unloading, crushed stone or gravel is usually scattered and remain on Earth. Additional purchase and transportation increases the price of the entire construction.

When choosing a mixture for laying blocks it is desirable to give preference to adhesive compositions of special purpose. Their price is definitely higher than the cement mortar. But consumption is an order of magnitude less. In addition, the laying of foam concrete on the glue is much better preserved heat.

When building a house of foam blocks with a facing brick, it is possible to facilitate calculations using the electronic calculator in ON-LINE mode. Ordering the estimate to the house of foam blocks turnkey, it is advisable to contact several contractors at once. All prices are different, so it is not difficult to choose an option acceptable at cost and execution timing. If necessary, in the estimate to the house you can always make amendments.

Species and features of estimates

Methods of drawing up estimates

Calculation of construction estimates

Estimated costs (costs) It is intended for a grouping of the upcoming expenses of the enterprise, aimed at carrying out any activity. In addition, there are estimates aimed at financing the activities of any enterprise or organization. The goal may be the implementation of design or construction work and the like. In our article, we will talk about the types of estimates, the methods of their compilation, we give an example of calculating the construction estimate for the improvement of the territory.

Many facts of economic activity require estimated calculation. The estimates are of different species, it depends on the type of activity of the organization, its organizational and legal form. Thus, production companies constitute estimates for production costs, non-profit organizations - estimates of income and expenses, construction - specialized construction documentation, which includes estimates for the implementation of CMR (construction and installation work) and on the development of project documentation.

Types of Smith

Estimation costs for production

Includes the planned costs of manufacturing products, is compiled for each type of product manufactured.

It indicates direct, or variables, expenses that depend on the volume of products:

• material costs;
• sales of production workers and insurance premiums;
• depreciation deductions;
• other expenses directly related to the production of products.

Here is formed incomplete cost of product.

Such cost estimates are used when calculating the normative value of the finished products, according to which it will be taken into account in the warehouse, and the selling price at which this product will be implemented to buyers.

Estimated production costs makes it possible to control the use of resources - not to recalculate material costs, timely detect deviations of actual indicators from planned, analyze and eliminate the causes of deviations. Without production estimates it is impossible to control the actual costs.

Revenue estimates and expenses

In the estimates of the income and expenses of the HOA (partnership of owners of the property), TSN (real estate owners), garage cooperatives, the horticultural non-profit partnerships indicate the amount of membership and (or) target contributions that are on the content of a non-profit organization, and in expenditures - all produced Her expenses.

In the expenditures of such organizations, including the wages of the accountant and the Chairman, the costs of protection, utility costs, garbage export, fire safety, etc. are approved by estimates by the general meeting of owners.

At the end of the year, the Audit Commission checks the validity of the costs, their documentary confirmation, compliance with the actual expenses of the costs specified in the estimate.

Construction estimates

Compiled on construction and installation work on the repair, overhaul of buildings and equipment, for the reconstruction and construction of new facilities (buildings, residential buildings, cottage settlements), landscaping of the yard territories, the gasket of roads, etc., as well as on design and survey Work on construction.

3 components of the estimate of the SMR:

1) direct costs;

2) overhead;

3) Estimate profit.

The estimates for investment projects are laid on the costs of design and survey and construction work, the profit should be obtained by a contract organization from performing work.

As a rule, the price in investment contracts and construction contracts of the contractual contractual (i.e. free, not tied to anything).

The cost of construction is determined at the stage of preparing design and estimate documentation, taking into account economic, geographical and natural factors, local conditions. Subjects of investment activities (investors, customers-developers, contractors) are independent and equal, so the price of capital construction facilities is established by mutual agreement of the parties.

The cost of construction can be determined at different stages, for example:

• design work (compilation of general plan, sketches, etc.);
• construction and installation work (directly execution of construction work);
• commissioning work on the commissioning of the necessary equipment on the object under construction.

Prices in building estimates are determined on the basis of a variant and flexible approach without tight regulations and excessive centralization. Select the optimal cost, deadlines and quality of projects allow contract trading.

The cost of construction products and production depends on demand: the more in demand housing, the more expensive 1 m 2 of the living area and the more the residential buildings are erected.

The estimate can be any participant in the investment process:

• designer working under the contract with the customer. In this case, the estimate usually make up a resource method or in a basic level using a solid price;
• the customer - determines the preliminary cost of the investment project or constitutes an investor estimate for the package of tender documentation;
• the general contractor is determining the cost through contract trading.

Depending on who from the subjects of investment activity was estimated, the following types are distinguished (Table 1).

Table 1

Types of construction estimates

The method of determining the estimated cost of the investment project, the normative base used and the procedure for carrying out mutual settlements is negotiated by the customer and the contractor and are recorded in the contracting contract.

Local estimates

The consolidated estimated calculation of the object under construction is compiled on the basis of local estimated calculations (estimates), which, in turn, are compiled on the basis of physical volumes of work, constructive drawings of elements of buildings and structures adopted by the work methods and, as a rule, for each building and construction types of work.

In contract agreements, consolidated stages of the performance of work can be provided - technologically completed complexes of construction and installation work. They may make up separately local estimates. For example, in the estimates on the buildings, underground and ground parts are highlighted. This allows the customer to be calculated with the contractor for the completed stage of work. By relatively simple objects, the category of estimated cost per sections may not be made.

The result resulting as a result of the estimated calculation in the local estimate is direct costs. Next, the size of overhead and profits are determined. Overhead costs are charged with direct costs percentage. After that, the total flow rate is calculated. Profit is charged on it (also in percentage terms).

Determination of the cost of construction

The cost of construction can be determined:

• in the project - according to integral estimated standards (price lists, enlarged estimated standards -Un, enlarged rates - UR), enlarged indicators of the cost of construction (EPS) and cost indicators of analog facilities;
• by shifts to typical, reusable and individual projects, tied to local construction conditions, and the estimates made on working drawings using the price lists intended for this purpose (USN, UR).

Local estimates on the purchase of technological and engineering equipment are compiled on the basis of specifications on the equipment of the manufacturer, the drawings of the technological part of the project documentation, factory price list and stock price of wholesale prices for equipment.

Note!

The cost of equipment defined on the basis of wholesale prices for industrial products includes costs for the delivery of equipment to construction warehouse, costs for packaging, packaging, equipped and sales charges, equipment equipment and warehouse costs.

Due to high inflation and instability, it is impossible to develop single rates for certain types of work, the cost of machine-hours, operated machines and mechanisms, determine the wage level. In this regard, coefficients apply to estimated prices approved by the Gosstroke of the Russian Federation in 2001

The coefficients show a change in value relative to the specified price level taken as the base.

Corrective coefficients (indices) are developed by regional pricing centers in construction (RCCC), which once a quarter, and in Moscow - monthly, publish a collection of coefficients of recalculation of the estimated cost of construction and installation work.

Our dictionary

Current level of value - The level of value determined by prices acting at the time of determining the cost.

Basic level of value - The level of value determined on the basis of estimated prices. Designed to compare the results of investment activity at different periods of time, economic analysis and determination of the cost at current prices.

The method of drawing up intelligence using previously approved single rates and bringing them to the scale of the current period with indexes is called basic-index.

Another common method of drawing up estimates - resource: For each type of work on the collections of the GESN-2001 in natural meters, the necessary material and technical resources are determined, the costs of operation of machines and mechanisms, labor costs of workers. Prices and tariffs for specified resources are accepted by the current, that is, at the time of the preparation of the estimate, or with a forecast for their possible change.

The resource method allows you to quite accurately determine the estimate cost of construction at any time. The necessary resources are set on the basis of the project documentation.

At the same time, the local resource statement is first drawn up, and then on its basis - the local estimated calculation.

Object estimated calculations

Object estimated calculations (estimates) They are drafted for the construction of each individual building and structures on the basis of local estimated calculations (estimates) for certain types of work and costs of buildings, structures and all-wide work and determine the overall size of all costs associated with the construction of the facility.

Approachable calculations (estimates) included in object estimates agreed with contracting construction organizations are the basis for determining the estimated value of the object under construction.

Object estimates take into account the cost of all types of construction and installation work, the costs of equipment, fixtures and inventory.

To determine the full estimate cost of the object, in the object estimate at current prices additionally include funds for the coating of limited costs:

• on the rise in the cost of work performed in winter, and other similar costs included in the estimated cost of construction and installation work;
• other works and costs that are determined as a percentage of the value of each type of work, costs or on the result of construction and installation work on all local estimates;
• reserve funds for unforeseen work and costs provided for in a consolidated estimated cost of construction costs to reimburse the cost of the contractor, the size of which is determined by a separate coordination between the customer and the contractor.

If the value of the object can be defined on the local estimate, the object is not compiled. In this case, the role of object estimates performs the local estimate, which indicates the means to cover the limited costs in the same manner as for object estimates.

For your information

In the object estimated calculation, as a result, indicators of a single cost per 1 m 3 volume, 1 m 2 of the area of \u200b\u200bbuildings and structures, 1 m of the length of networks, etc.

Object estimates compiled on working drawings, coordinated with the contracting construction organization and approved by the Customer, are the basis for settlements for the work performed. The quality of the construction products price, therefore, the results of the production and economic activities of contracting organizations depends on the quality of object defines.

Consolidated estimated calculation

The consolidated estimated calculation of the cost of construction of enterprises, buildings and structures or their queues determines the estimated limit of the funds necessary to complete the construction of all objects provided for by the project. Compiled on the basis of object estimates (object estimated calculations) and estimated calculations for additional costs, not recorded in object and local estimates.

Based on the approved consolidated estimated calculation of the cost of construction, the limit of capital investments in the financing of construction is determined.

Each row of the consolidated estimated calculation corresponds to the object data of the estimated calculation (object estimate) to individual objects, work and costs and has a reference to the number of these documents.

In the consolidated estimated calculation, a separate line provides for the reserve of funds for unforeseen work and costs:

• no more than 2% - for the objects of the social sphere;
• not more than 3% - for production facilities.

When drawing up a consolidated estimated calculation, current prices are used.

Approximate list of chapters of consolidated estimated calculation of the cost of industrial and housing and civil engineering:

• Preparation of the construction area.
• Basic construction objects.
• Objects of utility and maintenance.
• Energy facilities.
• Objects of transportation and communications.
• External networks and water supply, sewage, heat supply and gas supply.
• Improvement and gardening of the territory.
• Temporary buildings and structures.
• Other works and costs.
• The content of the Directorate (technical supervision) of the enterprise under construction.
• Preparation of operational frames.
• Design and survey work, author's supervision.

The consolidated estimated calculation submitted for approval as part of the project is attached with an explanatory note, in which:

• reference to the territorial area where construction is located;
• the level of estimated prices in which the calculation is drawn up;
• the list of estimated standards catalogs adopted for compiling estimates for the construction of objects;
• name of the General Contracting Organization;
• features of determining the estimated cost of construction work;
• features of determining the estimated cost of equipment and its installation.

Note!

In practice, in the construction of large facilities, in addition to capital investments in the construction of the Object itself, capital investments in the construction of the base for the needs of the construction of this structure are envisaged.

To this end, separate consolidated estimated calculations are drawn up for housing and civil engineering and to create the construction industry base, which are included in the cost summary together with a consolidated estimated calculation of production facilities. The total estimated cost of construction in these cases is determined by the cost summary that combines two or more consolidated estimated calculations.

If several investors participate in the construction of objects, then according to the results of the consolidated estimated calculation, the costs of equity participation in the construction of each shareholder are indicated.

Make up the estimate

Consider the methodology for the preparation of estimated calculations on the example.

Example

The customer of work on the improvement of the courtyard of the courtyard is the control area, the Contractor, a contracting organization, which is engaged in the improvement and gardening of the territory.

Object work is carried out on the basis of a contract and estimated documentation.

Scheduled road works and gardening.

At the first stage, the Contractor is a statement of planned types of work, indicates their volume and method of execution (Table 2).

table 2

Statement of planned types of work

Based on the statement of planned types of work, material costs (Table 3) and wages of workers participating in the project are calculated (Table 4).

In the statement of material costs indicate the amount of materials necessary for work on the improvement of the territory and their cost at current prices.

Table 3.

Calculation statement of material costs

In the wage calculation statement indicate:

• scope of work performed by the staff of the contract organization;
• watch tariff rate;
• additional salary;
• foundation for labor remote (Fot) for each type of work. Calculated by the formula:

Additional wages are calculated only for heavy work and is 15% of the main salary.

Table 4.

Value for calculating wages of workers

The estimates are also laid and the cost of maintenance and repair of special equipment, which is used in construction, - bulldozers, excavators, dump trucks.

We give the calculation of the value of 1 MASH.-H bulldozer. The source data is presented in Table. 5, the results of the calculations are in Table. 6.

Table 5.

Data for calculating 1 Mash.-H Bulldozer

Table 6.

Calculation statement 1 Mash.-H bulldozer

The rate of working time of the bulldozer to the device with a coating of asphalt concrete - 20 hours, on the gardening of the territory - 5 hours. Accordingly, the cost of maintenance and repair of the bulldozer will be:

• when performing road works - 51 999 rubles. (2599.95 rubles. × 20 h);
• the device of lawns - 12 999.75 rubles. (2599.95 rubles. × 5 h).

In the work on improvement, excavator and dump trucks were also occupied. Maintenance and repair costs will be:

• when performing road works:

excavator - 48 250 rubles;

dump trucks - 60 230 rubles;

• work on the device of lawn:

excavator - 10 150 rubles;

dump trucks - 12 350 rubles;

• facilities for planting trees:

dump trucks - 12 350 rubles.

Based on the calculations, we will make local estimates for each type of work (Table 7-9), given that:

• overhead costs - workers;
• other expenses - ;
• estimated profits - 15% of the cost of costs;
• VAT - 18% of the cost of costs + estimated profits.

Table 7.

Local rejection on the device of asphalt concrete coating of the roadway, sidewalks and tracks

Table 8.

Local Estimation on the device of lawns

Table 9.

Local estimate for planting trees and shrubs

Local estimates are combined into an object estimate, which summarizes the amounts of expenses for each type of work from the local estimates.

The object estimate for the improvement of the courtyard area is presented in Table. 10.

Table 10.

Object estimate for the improvement of the courtyard territory

So, the cost of work on the improvement according to the object estimate was 443,284.98 rubles.

The contracting organization for the won tender concluded with the management agreement for the improvement of the territory of the yard in the amount of 443,284,98 rubles.

Output

Compilation of estimates is important for the company's economic activity. The main purpose of the estimate is to determine the number of regulatory resources to perform the task. Competently compiled estimated documentation with a clear template and a clear structure, especially for the construction industry, is the basis of the success and profitability of the company.
