Estimate for the construction of a residential building from aerated concrete

Each serious construction begins with the preparation of project documentation and an estimate. This document allows you to perform calculations and evaluate the scope of work, as well as control the expenditure of funds during the construction process. It is rather difficult to make an estimate on your own without an understanding and understanding of construction processes. As a rule, in such situations, they turn to large construction companies, whose staff provides for the presence of an estimate department. In this article, we will tell you how the estimate for the construction of a house made of aerated concrete is carried out.

The purpose of the construction budget

The estimate for the construction of a house made of aerated concrete is the main financial document, which is an integral part of the contract for the construction of the construction company of the developer. The main components of the document are two sections:

• purchase of building materials;
• execution of construction works.

In addition to the main part, the calculation of technical and organizational issues is carried out:

• calculation of the scope of work;
• construction period;
• technologies used;
• amount of material;
• the number of specialists involved in the construction site;
• stages of project financing.

The convenience of the estimate allows you to control at any stage of the construction process, track the work schedule. Experts believe that a well-compiled estimate fully pays for itself and justifies the planned construction. Another advantage of the document is the ability to minimize bureaucracy in various instances, it helps the customer to present a picture of all construction processes, and also makes it possible to make amendments before the start of construction.

For information! You can order project documentation with full calculation from several construction companies at once, so you can always choose the appropriate option for your construction by comparing documents, quality indicators of materials and understanding the difference between them.

Large construction companies that value their reputation can invite the customer to discuss the nuances, and also help to reduce the cost of the estimate without losing the quality of the structural features of the house from the gas block.

Type of estimated characteristics

Specialists perform calculations in three ways: labor-intensive, universal and deployed.

Labor cost estimate

It is carried out to determine the amount of work performed by the contractor's teams. This method allows the contractor to negotiate with the customer, discuss all the working moments and receive funds to ensure wages. Wages, as a rule, are calculated from 1 square meter of work performed. This method is the best option for a low-budget project.

Universal estimate

It involves accounting and listing all building materials used, taking into account the real market value, their delivery. The advantage of this method is the constant control by the customer of the movement of work, as well as the ability to carry out a partial check on the cost of each material in the context of types. Such a document consists of 60 lines:

• from 35-40 positions on the materials used;
• 7% additionally contributed costs for transport services and its depreciation of the total cost of materials;
• overheads;
• staff salaries;
• it is possible to rent premises;
• taxes.

For information! The universal method involves hiding the item “planned profit” in the subcategory wages or cost of building materials.

Detailed estimate

Such an estimate involves a full calculation of all costs for a turnkey aerated concrete house. This is a complete package estimate documentation, compiled in accordance with applicable standards and legislation. A detailed estimate is compiled on the basis of special technological maps, cost estimates, specifications and types of work. The main advantage of this document is a complete understanding and accessible presentation of cost items for a typical average customer.

The cost estimate can range from $50 to $200, depending on the complexity of the structural elements of the project.

Estimate for a house made of aerated concrete

If you do not have the opportunity to order turnkey estimate documentation from specialists, it is quite possible to compile it yourself. The main thing in the process of calculations and allocation of positions is to take into account all the construction nuances and possible risks. We propose to analyze the main points and draw up an estimate for the construction of a two-story aerated concrete house with an attic with a total area of ​​120 sq.m.

• The foundation is shallowly buried with reinforced concrete tape, grade M250 is used as cement, reinforcement is made with 16 fittings. The cost of the foundation is: 1510 thousand dollars, where 1 sq.m. is equal to 126 dollars.
• Floor on the ground will cost 1510 thousand dollars.
• The construction of external wall structures of the first floor, taking into account window and door lintels, and additional materials for laying walls from the gas block, will cost 3,180 thousand dollars.
• Internal wall structures, which are 2.2 meters high, will cost $950.
• Construction of the outer walls of the second floor. This part of the estimate includes the cost of paying for equipment (KAMAZ all-terrain vehicle), loading and unloading blocks, and special glue for aerated concrete. The cost of works is 2200 thousand dollars.
• Internal walls of the second floor. In this part of the document, the costs for sand, steel angles and die-cut tapes are included. The cost will cost $ 750.
• The flooring device consists of monolithic reinforced concrete, with reinforcement in each wave. Height 11 cm, thickness 10-17.5 cm. The armored belt is one-piece with a common overlap, concrete is used grade M300. Openings for ventilation, a sewer pipe and a ladder were left in the finished floor. The cost of the work will cost 2100 thousand dollars.
• Roof device. This section includes soft tiles, ventilation outlet and cap, end and eaves profiles, mastic for tiles. The cost of the work will cost 3850-4000 thousand dollars.
• Attic insulation. This section involves warming the room with windproof fabric and vapor barrier. Of the materials you will need double-sided tape, fasteners (nails, screws), vapor barrier, thermal insulation. The cost will be $1,100.
• Blind area. To insulate the structure, a profiled membrane, double-sided tape, loose pillows for making, equipment rental. The cost of work will cost $ 700.

You can make such an estimate in the usual office program Excel. For a more detailed acquaintance with the phased preparation of estimate documentation, you can read the reviews on the forum of the owners of houses made of aerated concrete
