How to make an estimate for construction work? Local estimates for construction work. The scheme

Development of design estimates is an integral and very important component of the construction of civil or industrial facilities, the reconstruction of buildings, their capital or ongoing cosmetic repairs. Drawing up estimates for construction work, they receive data (results of economic calculations) that allow to evaluate the feasibility of the project and accurately determine the necessary costs for its implementation.

Estimated business in construction

The importance of the professional activity of specialists in the cost-sharing can not be overemphasized. The package of documents formed by them is an effective tool for monitoring and planning. It provides an opportunity to find out the size of the required capital investments, to finance, keep records and records, analyze the results of the executed.

Most of the estimate documentation - the calculations performed for the construction of departmental facilities and houses. At the same time, the sample budget for construction works for individuals and budget organizations is different. If the first priority is the cost of paying workers wages and calculating the commercial value of building materials, then the second case is somewhat different. It is important for them to strictly comply with regional and federal rates, the correct application of sectoral and territorial coefficients in the calculations.

Types of construction estimates

The practice of pricing provides for the classification of budget documentation:

• On the stages of construction - actual, executive, tender, conceptual;
• By types of works - finishing, repair, construction, etc .;
• On the components of the calculation itself (isolated and separately finished) - consolidated, objective or local.

Calculation methods

The estimate for repair and construction works can be calculated in various ways. Let us briefly consider what they are.

1. The base-index-estimated cost, determined on the basis of unitary rates operating in the region, is translated by indexing to the current price level (the recalculation indices for the subjects of the Russian Federation are set by the RCSs-the regional centers for pricing in construction-quarterly or monthly).
2. Resource - compilation of estimates for construction works by this method involves the calculation based on actual tariffs, current prices and quotations for labor, technical, material and other resources (lack of method in its complexity and complexity of justification).
3. Resource-index - both instruments of resource and index methods are applied simultaneously .
4. Basic-compensation - the basic indicators of value, formed at the time of the beginning of construction, are adjusted, based on the actual additional costs associated with changes in tariffs and prices.
5. Analogies - to determine the amount of costs, a data bank is used (a sample of the estimate for construction work on the construction of a similar building or building).

Scheme, or key components

Regardless of the calculation methodology, which is used to form estimates for construction work, you need to make a calculation:

• Direct costs, including the cost of products and materials to be used, as well as investments related to the acquisition, lease and operation of the necessary machinery and machinery, payment of wages to workers (taking into account the current tariff rates, territorial and federal rates, established standards for the consumption of building materials) ;
• Overhead costs that go to ensure the organizational and management part of construction, as well as limited and not limited costs (payments on loans, voluntary or compulsory insurance, and others);
• Planned savings (estimated profits), funds that are intended for material incentives for employees and the development of the material and technical base of the contractor.

Local estimates for construction work: what is it, what sections does it include?

Local estimates are the basic primary documents that are compiled for separately taken types of costs and works (erection of foundations, walls, staircases, etc.), the main structural elements and engineering equipment for a particular object of a construction project, reconstruction or repair. Only direct costs are taken into account.

Calculation of the estimated cost is made based on the volumes defined in the working design documentation. In other words, we can say that the local estimate for construction work is a statement in which unitized rates are grouped into sections. It fills in the fields in the columns reserved for specifying resource codes and price ciphers, descriptions of the types of repair and construction works and the costs required for their production, as well as the measurement parameters of those and the number of units. Further prices, recalculation factors and correction are placed. Having carried out the corresponding calculation, the final value of each item is obtained.

How to determine the types and scope of repair work for the preparation of estimates?

Precise calculations are needed not only when building new buildings. In order to start the formation of the estimate documentation for capital, current or repair repairs, the expert-estimator does not always need to personally inspect the object. The estimate for repair and construction works can be calculated on the basis of a defective sheet containing accurate data on what flaws are identified, what needs to be done and in what quantities.

Why are estimates made?

A detailed calculation of the estimated documentation allows the customer to avoid possible misunderstandings with the general contractor and exclude unspecified additional costs. The reliability of calculations of the cost of construction depends on its planning and efficiency of capital investments.

An expert estimate of estimates allows you to determine whether all works and materials are taken into account by the estimator, whether deviations from quotations, specifications and other basic criteria established by the legislation are not admitted, whether there is an understatement or overestimation of the price.

How to make an estimate for construction work, without making mistakes?

When constructing large industrial and residential objects correctly determine their estimated cost is not so simple. Prices for equipment, tools, materials needed for construction, change over time. Also, do not forget about the risks associated with force majeure.

The quality and accuracy of calculating the estimate are determined by various parameters. The most important of them is always the professionalism of the engineer-estimator, who can take into account all the nuances. First of all, we are talking about the correct application of recalculation indices and all possible correlation coefficients (for rise in price, inflation, etc.), the correct choice of territorial unit prices (an error in choosing the name of the type of construction work can lead to a significant change in the cost indicated in the budget documentation ).

Excellent assistants, which allow you to quickly formulate estimates for construction work, - software automation calculations ("GRAND-estimates", Smeta.ru, "Stroy-Info" and others). However, by simplifying the process, they do not abolish the need to have in-depth knowledge and experience.
