Who checks the estimates. Why and how to check estimates in construction

Any customer is interested in an economically justified estimate with a minimum price and a high-quality project, and a contractor in the maximum benefit from the construction process. Against this background, there are many disputes and conflicts. An independent review of estimates is designed to resolve misunderstandings at any level.

What is expertise and why is it needed?

Examination of the estimated cost is able to timely identify overestimation or underestimation and minimize fines during inspection by regulatory authorities. This is the most popular type of analysis among all construction expertise. It is carried out before the conclusion of a construction contract or during technical supervision.

The objectives of the examination of our company:

Examination of estimates for economic errors:

identification of inconsistencies in the application of prices, coefficients, etc;
monitoring and analysis of prices for materials and equipment;
verification of actual costs when calculating overheads, travel costs according to the accounting data of a particular enterprise, other real costs in acts of issue. works;
other checks in accordance with applicable pricing requirements.

Identification of technical errors:

reconciliation with drawings of construction volumes in estimates;
verification of construction works in drawings in accordance with architectural solutions and technology, technical specifications;
verification of the scope of work in accordance with the executive documentation;
control of the correct use of materials in accordance with the conditions of the project;
reconciliation of engineering surveys in the project with those applied in the estimates of soil groups, density, working conditions, etc.;
reconciliation of actually purchased materials with the expense in the acts of work performed.

Appearance check:

separation of documentation in order to optimize taxation for repairs and reconstruction;
checking the execution of estimate documentation (availability of approvals, seals, etc.), completeness.

An independent cost estimate examination can be carried out both as a separate study and in combination with other technical examinations. It can also be ordered before the mandatory state examination of objects that are legally lawful to carry out only by the state. expertise. This is convenient if you need to reduce the time for review and return for revision.

For reference: “Objects subject to mandatory state registration. expertise: unique buildings over 100 m in height, 100 m in span, especially dangerous and technically complex facilities, military facilities, facilities for the disposal of hazardous waste, historical values and monuments, facilities in the internal sea waters of the continental shelf of the Russian Federation, facilities on the territory of 2 and more subjects of the Russian Federation, the source of financing of which is federal”

Our company is accredited to conduct a non-state examination of the cost of the project. The examination of estimates of our company does not differ from the state procedure by the methods of inspections and the quality of the final product. The test results are legally binding. The conclusion of the examination can be used in the arbitration courts of Russia, investigating authorities, etc.

Compared to state expertise, we offer our clients a complete absence of bureaucracy and pleasant conditions for cooperation with us. It:

the cost of work at the level of public services;
short deadlines for work;
announcement of preliminary results;
the possibility of verifying part of the documentation;
unbiased attitude towards the customer or contractor.

Important! State expertise is carried out before the start of construction during the development of the project. While independent verification at any stage of cost formation and work execution!

We are ready to analyze the documentation at the design stage, the conclusion of a contract, the performance of work or the conservation of construction.

What documents does our company check?

Checking the estimated cost consists of the analysis of estimates, the correct understanding of the drawings, as-built documentation, and accounting documents.

The list of examination of estimate documentation, which is checked by our organization:

examination in the consolidated estimate for compliance with the data on the project, terms of reference, terms of the contract;
offers for public and private tenders;
commercial proposals for the calculation of contract prices, acts of performance of work at commercial prices;
certificates of work performed KS-2 (including the actual cost of materials, travel expenses, actual use of materials);
calculations of resource consumption according to M29 (if necessary, departure to the construction site);
defective statements during a stop or during a defrosting of construction;
separate calculations (the cost of design and survey work, technical supervision, field supervision, insurance fund);
analysis for the separation of estimates by type of construction: overhaul, reconstruction;
individual cost estimates for the manufacture of your own products, developed individual prices, the cost of machine hours of construction equipment.

Also, our enterprise can be a member of the commission for acceptance of works, if an examination of the estimate according to 44FZ is required to determine the degree of safety of the project.

How customers are deceived

According to the results of our internal research, more than 70% of the estimate documentation is overstated. This may be a deliberate "inflating" the price of construction or errors due to inattention, low qualifications. Also, a situation often occurs when the contractor, wishing to win competitive bidding, underestimates the scope of work or completely excludes part of the work. Upon signing the acts, this increases the cost, and the customer incurs losses.

The most common errors:

Increase in the cost of equipment, material resources in the resource method of calculation;
Overestimation of the cost of machine hours in the operation of mechanisms, construction equipment, overspending;
Increase in labor intensity in direct costs, which entails overpayment of travel expenses and wages of shift workers;
Incompetent use of profit ratios and calculation of overheads;
The use of mixed prices of materials in the basic-index and basic-compensation methods. The initial prices, which are then indexed, may be for 1984 and 2018.
Duplication of individual lines of work, which is already included in the main price.
Inflated commercial rates.
Incorrect application of appreciation coefficients, tariff scales for workers' wages.
Incorrect selection of estimates - analogues.

These are not all the tricks that unscrupulous contractors of construction work most often consciously resort to. It is difficult for an inexperienced technician or a novice to repair to determine the source of the error. Therefore, it is better to entrust the work to experts.

The reliability of determining the estimated cost is also needed by contractors that conclude contracts with budget organizations. This will save you from unnecessary nerves and time spent on finalizing the estimate.

The procedure for conducting an examination

According to the current legislation of the Russian Federation, the terms of the examination are 3 months. But our team of professionals performs the scope of work in the agreed order, based on the specifics of the project. Most often, the terms are minimized by two or even three times.

Before starting to determine the reliability of the estimated cost, we discuss with the customer the objectives of the research, verification methods, scope of work and terms.

List of documents for examination:

Project documentation.
Design assignment.
List of construction volumes of work.
Defective statement or technical inspection report (for overhaul facilities).
Passport data of the object.
Contact information about the design organization.
Application for each audited estimate.
Official letter addressed to our leader.

Our actions:

Analysis of budget documentation after signing the contract.
Recalculation of the cost of construction in case of errors.
If necessary, protection of identified errors to contractors.
Issuance of an official conclusion on the progress of the audit, which indicates the amount of overestimation or underestimation of the cost and detailed recommendations for adjustment.

Service cost

The initial price for checking one line of the estimate is from 80 rubles. The cost of the service depends on:

the level of complexity of the object, its uniqueness;
quantity and quality of source documents;
individual requirements of the client;
the urgency of the work.

Depending on the form in which the project documentation is provided, one can judge the labor costs of the checking expert. Source documentation could be:

Full. This is a ready-made project with detailed detailing of technological units, ready-made technical solutions, an electronic estimate file in the software package; ready as-built documentation, defective statement; contractual price with a complete set of drawings.
Partial. Photos of the work performed, an incomplete list of the scope of work, lack of primary accounting documents to verify actual costs, verification according to the drawings of stage P.

There are cases when the actual work performed is checked, and the as-built documentation is completely absent or the project is developed poorly. Then our specialist can go to the object and make clarifying measurements.

The list of services for the verification of design and estimate documentation:

Checking the positions of local estimates of unique industrial facilities, architectural monuments, with the full amount of information - from 80 rubles / item;
Checking the positions of local estimates of unique industrial facilities, architectural monuments, with a partial amount of information - from 100 rubles / positions;
Checking the positions of local estimates of capital construction, repair, reconstruction with the full amount of information - from 80 rubles / position;
Checking the positions of local estimates of capital construction, repair, reconstruction with partial information - from 100 rubles / item;
Checking the positions of acts of completed work of any type of construction in the absence of an executive scheme, project, drawings - from 100 rubles / positions;
Checking the scope of work in the design documentation - to be agreed;
Verification of actual overheads according to accounting data for the reporting period;
Checking settlements in the SSR;
Checking estimates for design and survey work - from 4000 rubles / estimate;
Checking commercial prices - from 80 rubles / positions;
Departure to the construction site in Moscow - from 3500 rubles;
Departure to the object in MO - from 4000 rubles.

Why is it profitable to cooperate with our company

Determining the reliability of the estimated cost is a painstaking and highly skilled work that must be trusted to professionals. We have extensive experience in inspections in all areas of construction, and our experts undergo annual recertification and constantly monitor pricing changes. Each employee has his own narrowly focused activities (plumbing, general construction, electrics, etc.), which positively affects the quality and timing of work.

The estimates checked by us can be applied as evidence in the Arbitration Courts, in case of disputable situations with budgetary organizations. We guarantee our clients:

Saving the final cost by at least 10% of the original price in 99 cases out of 100. This is much cheaper than your inspection costs.
Guarantee for verified budget documentation. After the end of the work, we, if necessary, are ready to prove our case, conduct official correspondence and support it with references to the Laws on pricing and rationing, recommendations of the Ministry of Construction of the Russian Federation;
Professionalism and many years of experience of engineers. Each specialist thoroughly knows the construction technology, pricing, collections on labor rationing (FER, TER, OSN, etc.) and can work in any programs for estimates.
Free consultations on any issue during the inspection.
Strict observance of agreements, terms of work.
Competent execution of the conclusion.

Ordering an estimate check at any stage of work will save you from unnecessary fines and save funds for further business development and other purposes. This is a procedure that is equally necessary for a construction company or an individual during construction, repair. The cost of the services of our company is economically justified, and you will only benefit from cooperation with us.

General information on the topic:

Checking estimates

Estimate analysis is a very important part of the process of interaction between the contractor and the customer. After all, the process of construction and installation work itself cannot be planned 100% in advance, which means that the initial cost indicated in the estimate should also change following changes in the work done. In addition, quite often, unfortunately, the customer (rarely the contractor) pays little attention to checking the estimate documentation at the initial stage before the start of work (if it is drawn up at all), hoping for the decency of the contractor or for the Russian "maybe". As a result of such carelessness, after some time it turns out that the contractor bills the customer for payment for his services much more than the amounts they cost, including in the scope of work a lot of things that he did not do and the cost of materials that are much higher than average market prices.

The optimal algorithm for the work of the contractor and the customer is as follows:

Drawing up a statement of scope of work, with mandatory approval and agreement by the customer and contractor;
Preparation of estimate documentation according to this sheet by the contractor and submission to the customer for approval;
Checking and agreeing estimates by the customer;
Acceptance of work by the customer in accordance with the bill of quantities and estimates (if necessary, estimates are adjusted) on the basis of the Certificate of acceptance of work performed in the form KS-2;
Payment for the work performed according to the certificate of the cost of work performed in the form of KS-3.

Checking the estimates (analysis of the estimate) at the initial stage before the start of work will significantly reduce the cost of funds (any contractor lays at least 30% overestimation of the cost of his services). Verification (analysis) of the estimate documentation (which may change) in the process of work will eliminate unnecessary overspending on the purchase of additional materials and unnecessary work. Even in the most neglected case, when estimates were not drawn up and not checked at all, checking estimates can significantly save money due to the consistent restoration of the entire work process from scratch, however, this is much more labor-intensive and you will still have to say goodbye to part of the money (for production services control measurements, part of the overestimation of the amount of work that can no longer be verified, etc.).

Thus, checking the estimate will save you from many unpleasant surprises, such as:

overestimation of the volume of work performed;
exclusion of the cost of work that is not actually done (for example, hidden work);
exclusion of duplicate prices and works;
overestimation of the cost of materials and equipment, etc.

In accordance with the foregoing, one important conclusion can be drawn: the sooner the customer (or contractor) starts checking the estimates himself or entrusts professional estimate engineers with checking the estimates, the more he will save money and time. Thus, the analysis of estimates for construction and installation works will allow the most optimal use of material resources.

An object: Building

Purpose of the examination:
verification of the estimated calculation for compliance of the applied rates with the rates of the relevant estimated regulatory framework;
checking the conversion factors of the estimated cost of construction and installation works.

Technical means used in the examination:
Software:
software package "Construction Expert 2000"

During the examination, the following regulatory documents were used:

1. Methodology for determining the cost of construction products on the territory of the Russian Federation MDS 81-35.2004.
Approved by the Decree of the Gosstroy of Russia No. 15/1 of 05.03.2004

2. Estimate and normative base MTSN 81-98 for determining the cost of construction and repair and construction work.
Developed by MCCS "Mosstroytseny", approved by the Decree of the Government of Moscow.

3. Coefficients for converting the cost of construction, determined in the norms and prices of MTSN 81-98, into the current price level as of May 2007. Issue No. 73, Collection No. 05/2007-98.

As a result of checking the estimates, it was found:

1. Verification of the compliance of prices in the estimate provided by the Customer with the prices of the estimated regulatory framework MTSN 81-98.

1.1. The prices applied in the estimate do not partially correspond to the estimated regulatory framework MTSN 81-98. In positions 68 and 69, prices from the estimate and regulatory base of FER-2001 are applied.
1.2. The overhead rates used in the calculation of the estimate do not comply with MDS 81-35.2004. In the prices for construction works, the standards for new construction are applied instead of the standards for repair and reconstruction.
1.3 The estimated profit standards used in the calculation of the estimate do not comply with MDS 81-25.2001. In the prices for construction works, the standards for new construction are applied instead of the standards for repair and reconstruction.

2. Verification of the conformity of the applied conversion factors to the current price level with the "Construction cost conversion factors, determined in the norms and prices of MTSN 81-98, to the current price level as of May 2007"

2.1. The coefficients used in the estimate for conversion to the current price level correspond to the Conversion coefficients for the cost of construction, determined in the norms and prices of MTSN 81-98, to the current price level as of May 2007.

3. Verification of the correctness of the applied rates, cost and consumption of materials.

3.1. The prices for the materials attached to the prices do not correspond to the "Collection of estimated prices for materials MTSN 81.1-98".
3.2. Some of the prices have been applied incorrectly:
- when installing monolithic concrete walls, the price for the installation of strip foundations was applied;
- when installing partitions with insulation, separate prices are applied for the installation of partitions without insulation and the installation of insulation of building structures;
- for pasting walls with wallpaper for painting, the price for pasting walls with washable wallpaper was applied and artificial leather on a fabric basis was taken as materials;
- in the prices for concrete and plastering works, the cost of ready-made mortars and concretes is taken, while the preparation of mortars and concrete in construction conditions with the cost of components is additionally taken.

In view of the above, the estimate has been recalculated. The estimated cost of works on the reconstruction of the building was ** *** ***,** rubles (see Appendix 1).

Conclusions:
The estimate submitted for examination has a number of inconsistencies with the estimate and regulatory framework MTSN 81-98, which led to an excess of the estimated cost of reconstruction of buildings by * *** ***,** rubles, which is 10,82% from the declared value.

2. Analysis and systematization of the data obtained at the previous stages, performing the necessary calculations, processing the results.

2.2. Description of research papers
According to MDS 81-35-2004

I. GENERAL PROVISIONS
This Methodology is intended to determine the cost of construction of new, reconstruction, expansion and technical re-equipment of existing enterprises, buildings and structures, repair and commissioning works (hereinafter referred to as construction) carried out on the territory of the Russian Federation, as well as the formation of prices for construction products.

The distribution of objects, works and costs within the chapters is carried out in accordance with the nomenclature of the consolidated estimate calculation of the cost of construction that has developed for the relevant industry. If there are several types of completed productions or complexes, each of which has several objects, grouping into sections can be carried out within the chapter, the name of which corresponds to the name of the productions (complexes).
For certain industries and types of construction, the name and nomenclature of the chapters of the summary estimate may be changed.
The presented estimate documentation was calculated according to the TER edition of 2014 as of November 2017.

Notes on all quotes:
1) Replace local estimates with Local estimate calculation, see MDS 81-35-2004 p.3.16
2) The coefficients of constraint k=1.15 are not justified by the PIC.
3) Costs for temporary buildings and structures are taken into account twice, as construction and installation works and as a percentage of construction and installation works. These costs are accepted in agreement with the Customer-Investor. VZiS is not charged for the cost of equipment (see LSR No. 8 TP and others) only on construction and installation works MDS 81-35-2004
4) Costs for the Winter appreciation are taken year-round, but depending on the location of the object and the time of work, also in agreement with the Customer-Investor. For example Winter rise in price, in the region of Moscow, the estimated cost calculated according to TSN -2001 Moscow is included in each price and the Customer is not entitled to correct it. For the cost of equipment, the memory is not wound up (see LSR No. 8 TP, etc.), only for construction and installation works MDS 81-35-2004
5) Contingency costs are the expenses of the Customer-Investor. They are given to the contractor depending on the method of mutual settlement when they arise under the contract.
6) The cost of material resources and equipment of some positions is taken into account according to the price list. It is necessary to provide an agreement with the Customer-Investor. Monitoring of cost indicators indicating at least three suppliers and choosing the current price. If we take according to the method of state pricing, then the format for applying prices for work and materials should be the same. In the estimates, positions exceeding the market ones remain, and within the framework of the market they are replaced by expensive ones. It is not correct.
7) The cost of recycling is not subject to VAT.
8) For all estimates, in the presence of equipment, allocate the cost to the results. It is important for the Investor to know the cost of equipment for its operation and for accounting of working capital
9) In all estimates, exclude VZiS and ZU, as well as Unforeseen costs. They are taken into account in the SSR Consolidated Estimate.

CONCLUSIONS
Estimated documentation at the “P” stage of the Project is indicative, it is not recommended to enter into contractual relations on it, since after the introduction and approval of the Working Documentation, the estimated cost, as a rule, differs up to 50% upwards, in exceptional cases it theoretically decreases, subject to adjustment project documentation.
This estimate documentation is subject to revision upon comments. Malicious and obvious remarks were not revealed. The cost indicators of prices for work have not been adjusted, the indices correspond to the applied positions.
A detailed study of the project documentation of all sections is required. It is advisable to additionally order a Bill of Quantities from the designers. This section will help to correctly evaluate and prepare Local estimates.

Checking the estimate documentation is aimed at:

✓ the correctness of the prices that are applied;

✓ correct use of correction factors;

✓ error-free calculation of the scope of work in accordance with the project documentation;

✓ Compliance of prices for equipment and materials with market values.

Why is budget verification so necessary?

Analysis of estimate documentation is an important step in the relationship between the contractor and the customer. And the rationality of the money spent on a construction project plays a significant role in these relationships. The customer must be interested and convinced in the correctness of the estimate, in real compliance with market prices, and also in not overstating the scope of work.

An experienced builder knows that in practice there is no perfect match between the cost of the cost estimate and the primary results of accounting documents, including overheads, machines in operation and wages paid. Checking construction estimates includes the purpose of identifying unreasonably high prices.

What contractor makes mistakes in the preparation of estimates?

Often observed when checking construction estimates:

✓ Overpricing of building materials

✓ Acceptance of errors in the calculation of the scope of work

✓ Incorrect use of correction factors.

In practice, quite often the contractor seeks to extract the maximum profit from the work performed and deliberately overstates the cost of materials. In the case when verification of estimates, the customer controls the cost of materials of funds.

When calculating the amount of work, such errors are usually made as: incorrect compilation of mathematical calculations, inattention in calculating the amount of work based on the drawings. Together with the estimate, project documentation is provided, which makes it possible to carry out an analysis in the construction estimates for the reliability of the applied volumes of work.

Incorrect application of prices and the presence of correction factors in the estimate indicate the ignorance of the estimator of construction technology. Since the preparation of estimate documentation belongs to office work carried out outside the construction site, the estimator may, due to ignorance of the conditions of production work, when using correction factors, make errors in the estimates.

How are construction estimates checked?

If the customer is interested in saving money and spending it correctly, he can seek help from an independent organization that checks prices in estimates. With the help of a special program that allows the estimated price to be divided into its component parts (salary, cost of materials, overhead, estimated profit, operation of machines), a professional estimator checks local estimates and analyzes possible savings options.

In some cases, during construction, additional work may be identified that is not included in the estimate, or it may become necessary to replace the work. In these cases, it is necessary to make adjustments to the estimates. That is why technical control and analysis of the implementation of the estimate is so important in the process of work. An independent organization will help the customer track the progress of construction work.

Implementation checking budget estimates

It is often necessary for budgetary organizations to carry out an audit of budgeting in order to conduct tenders. The limited possibilities of a budgetary organization force the customer to approach the cost estimates of budgetary institutions in the most economical way. Checking the estimates of budgetary organizations is aimed at price analysis of the materials used, the discovery of expensive items and the search for feasible ways to save. Among other things, compliance with fire safety requirements and sanitary standards for the materials used is checked. In these cases, in a budgetary institution, the use of an analysis of the estimate helps to competently carry out repairs to the facility, as well as put it into operation for regulatory authorities.
