KP construction facility in the form of a linear or network diagram is intended to determine the sequence and timing of the implementation of general construction, special and installation work carried out during the construction of the facility. These deadlines are established as a result of rationally linking the deadlines for the implementation of certain types of work, taking into account the composition and quantity of the main resources, primarily work teams and leading mechanisms, as well as the specific conditions of the construction area, a separate site and a number of other significant factors.

According to the KP, the need for labor and material and technical resources is calculated in time, as well as the timing of the supply of all types of equipment. These calculations can be performed both for the object as a whole and for individual periods of construction. Based on the KP, they monitor the progress of work and coordinate the work of performers. The terms of work calculated in the KP are used as starting points in more detailed planning documents, for example, in weekly-daily schedules and shift tasks.

The procedure for developing a CP is as follows:

1) draw up a list (nomenclature) of works,

2) in accordance with it, for each type of work, their volumes are determined;

3) make a choice of production methods for the main work and leading machines;

4) calculate the standard machine and labor input;

5) determine the composition of brigades and units;

6) identify the technological sequence of work,

7) establish the shift of work,

8) determine the duration of individual works and their combination with each other; at the same time, according to these data, the number of performers and shifts are adjusted;

9) compare the estimated duration with the normative one and introduce the necessary amendments;

10) on the basis of the completed plan, develop schedules for the need for resources and their provision.

If flow charts are available, their linkage to local conditions is clarified (correspondence of deadlines, leading mechanisms, availability of required resources, etc.) and the output data of the charts are accepted as calculated for individual sets of works of the facility's KP. So, having a technological map for the installation of a typical floor and roof of a residential building, they take the installation time and the need for resources laid down in these maps to draw up a schedule for the construction of a house.

The initial data for the development of the CP as part of the WEP are:

1) GPP as part of the PIC;

2) standards for the duration of construction or a directive task;

3) technological maps for construction, installation and special works;

4) RD and estimates;

5) data on the organizations participating in the construction, the composition of the teams and the productivity they have achieved, the mechanisms available and the possibilities for obtaining the necessary material resources.

The KP for the production of works at the facility consists of two parts: left - calculated and right - graphic; hence such plans are called schedules. The graphic part can be linear (Ganges line chart, cyclogram) or network. The list of works is filled in in the technological sequence of execution with grouping by types and periods of work.

When grouping, you must adhere to certain rules:

1. If possible, you should combine, enlarge the work so that the schedule is concise and easy to read.

2. At the same time, the consolidation of work has a limit in the form of two restrictions: it is impossible to combine work performed by different performers (SU, sections, teams or units), and in the complex of work performed by one performer, it is necessary to single out and show separately that part of the work which opens the front for the work of the next brigade.

The scope of work is determined by the RD and estimates. The selection of volumes from the estimates is less laborious, but since there is no division of volumes into captures in the estimates, it is necessary to use the RD and specifications for them directly for individual works, controlling the correctness of the calculations for the estimates. The scope of work should be maintained in units adopted in the enlarged complex standards (UKN) or in the Uniform Rates and Prices (ENiR). The volume of special work is determined in terms of cost (according to the estimate) in the case when their labor intensity is calculated by output, and when using aggregated indicators, in the corresponding meters. The labor intensity of work and the cost of machine time are calculated according to various standards. The objectivity of the decisions of the KP is largely determined by the choice of the source of data on labor costs. The regulatory framework can be:

1) ENiR (MNIR, VNiR);

2) calculations based on ENiR;

3) estimated standards (SNiP, part IV, EPER);

4) enlarged complex standards (UKN);

5) specific production in natural (m / person-day, etc.), cost (rub / person-day, etc.) or volumetric-constructive measurement (person-day / floor, person-day / apartment and etc.).

The first three sources are based on data averaged for the whole country - this is their shortcoming. They calculate according to the current UNiR with an increase in the planned growth in labor productivity by maintaining a correction factor for overfulfillment of the norms. Along with the ENiR, they use local and departmental norms and prices (MNiR, VNiR). The actual performance in different organizations differs from each other and in comparison with the standard by 1.5 ... 2 times or more.

Calculations make it possible to more fully take into account the entire range of works, but their preparation is laborious and requires high qualifications. Rationing according to ENiR is a very laborious process. In this regard, in all large organizations, for planning purposes, aggregated norms developed on the basis of production cost estimates are used. Aggregated norms are compiled by type of work for a building or its part (section, span, tier, etc.), a structural element (installation of ceilings with welding of embedded parts) or a complex process (for example, plastering the internal surfaces of houses from expanded clay concrete panels, including plastering walls, slopes, rustication with a partial notch on the surface, mortar lifting and other related works).

The aggregated norms take into account the achieved level of labor productivity. In the absence of enlarged standards, they first make up a calculation of labor costs, the calculation results of which are transferred to the schedule. Enlarged complex norms (UKN), I developed in Glavstroi, have greater objectivity, but due to their averageness they cannot reflect the specifics of a separate team, object, specific working conditions.

The greatest accuracy is ensured by the use of information about the achieved performance of a given team on the same type of object (for example, a house of the same series). Less accurate calculations are based on the production of the same

The limiting number of workers who can work on a grip can be determined by dividing the front of work into plots, the size of which should be equal to the shift productivity of a link or an individual worker. The product of the number of plots and the composition of the units gives the maximum number of the brigade in this area. Minimization of the duration has a limit in the form of three restrictions: a) the scope of work, b) the availability of workers and c) the technology of work. The minimum duration of individual works is determined by the technology of their implementation, for example, concrete, plastering, painting and other works with "wet" processes. The number of shifts when using the main machines (mounting cranes, etc.) the number of work shifts is taken at least 2. Work without the use of machines, as a rule, should be carried out in only one shift. The shift of work performed manually and with the help of a mechanized tool depends on the available scope of work and the availability of workers. As a rule, with a sufficient front, it is advisable to plan these works only in the first shift, in which working conditions improve, the possibility of a clearer organization and management of work increases, and higher productivity is ensured. In addition, some jobs, such as finishing work, can only be done during the day shift. The performance of a number of works on the second shift, especially in the autumn-winter period, requires additional measures, such as lighting workplaces, walkways, additional labor protection measures, etc. However, the implementation of these measures does not completely eliminate the inconvenience of the second shift. Work carried out manually is assigned to the second shift only in those rare cases when the scope of work is sharply limited and the team (link) is forced to split up for shift work (for example, when laying brick pipes).

The number of workers per shift and the composition of the team is determined in accordance with the complexity and duration of work. When calculating the composition of the brigade, it is assumed that the transition from one capture to another should not cause changes in the numerical and qualification composition of the brigade. Taking into account this circumstance, the most rational structure for combining professions in the brigade is established among themselves.

Typically, brigades have an established composition, which is taken into account when compiling the CP.

The calculation of the composition of the brigade is carried out in a certain sequence:

1) outline a set of works assigned to the team (calculate the labor intensity of the works included in the complex from the calculation, select labor costs by profession and category of workers; 4) establish recommendations for the rational combination of professions; 5) on the basis of data on the time required by the leading machine to complete the intended complex, the duration of the leading process is determined by the formula; 6) calculate the strength of units and teams; 7) determine the professional qualification composition of the brigade. The complex assigned to the team includes all technologically related or dependent work necessary for the uninterrupted use of the leading machine. So, during the construction of the ground part of large-panel houses, which is carried out in two cycles, the first cycle, along with the installation, includes all the work associated with the installation (carpentry, special work, etc., preparing the house for painting work). During the construction of brick buildings in three cycles, in the first cycle of the construction team, along with installation and related general construction work, providing preparation for plastering work. In the second and third cycles, plastering and painting works are performed respectively.

In order for the strength of the brigade to correspond to the productivity of the leading machine, it is necessary to take the period of work determined on the basis of the estimated operating time of the machine as the basis for the calculation.

The quantitative composition of each link is determined on the basis of labor costs for the work assigned to the link and the duration of the leading process. The quantitative composition of the brigade is determined by summing up the number of workers of all the links that make up the brigade. Labor costs by profession and category are established by sampling from the calculation of labor costs. The number of workers by profession and category.

Work schedule- the right part of the KP - clearly displays the progress of work in time, the sequence and linkage of work with each other.

The calendar deadlines for the performance of individual works are established from the condition of observing a strict technological sequence, taking into account the need to provide a front for the implementation of subsequent work in the shortest possible time.

The period of readiness of the front of work in a number of cases increases due to the need to observe technological breaks between two consecutive works. For example, the installation of overlying reinforced concrete structures can be carried out only after (monolithic joints of the supporting structures acquire the necessary strength (at least 70% of 28). Technological breaks are not constant, they depend on a number of factors. Thus, the drying time of the plaster depends on the period year, temperature and applied methods - natural or artificial ventilation.If necessary, technological breaks can be reduced by using more intensive methods.Thus, when installing a monolithic joint, a different type and brand of cement, electrical heating and other methods of accelerating concrete hardening can be used. work depends on design decisions.Thus, the method of laying internal electrical networks determines the technological sequence of plastering, painting and electrical work.Hidden electrical wiring is carried out before plastering and painting work, and with open wiring, plastering work precedes installation of electrical wiring. The period of the year and the area of ​​construction also affect the technological sequence of a number of works. For the summer period, if possible, the main volumes of earthwork, concrete, reinforced concrete work should be planned, since their implementation in winter will cause an increase in labor intensity and cost. If finishing work falls on the autumn-winter period, then the completion of work on glazing and heating in the building is provided for in a timely manner that ensures the timely start of finishing work. If the amount of work on external and internal plastering can be performed during the warm season, then usually internal plastering is performed first, as this opens the front for subsequent work. But if during this period it is impossible to complete all the external and internal plastering, then before the onset of cold weather, work on external plastering is forced, while creating the necessary conditions for the subsequent implementation of internal plastering work in the autumn-winter period.

The main method of reducing the construction time of facilities is in-line execution of work. Works that are not interconnected must be performed independently of each other, and interconnected - continuously. If there is a technological connection between the works within the common front, the areas of their implementation are correspondingly shifted and the work is carried out simultaneously. In this case, it is necessary to take into account the rules of labor protection. For example, when performing installation and finishing work on the same grip during the day, finishing work should be planned in the 1st shift, and installation of structures in the 2nd and 3rd. When delivering the work schedule for the construction of industrial facilities, the order of commissioning of individual units, assemblies, production lines, launch complexes, as well as sections, blocks, buildings and structures is taken into account. For example, during the construction of a CHP, separate blocks of steam turbines are put into operation, during the construction of open-hearth shops, separate furnaces, etc. Taking into account this order of commissioning, a technological sequence of construction work and equipment installation is established.

When drawing up the schedule, the expediency of uniform consumption of basic resources, primarily labor, is taken into account. The uniform need for workers by profession is ensured by the consistent and uninterrupted transition of work teams from one work site to another in accordance with the principles of in-line construction. Equalization of the need for workers for the facility as a whole is achieved by redistributing the start and end dates of work. But this alignment is relative and is carried out only within the limits of a rational technological sequence of work.

The scheduling (right side) should begin with the leading work or process, which decisively determines the overall duration of the construction of the facility. Comparing with the standard, it is possible, if necessary, to reduce the duration of the leading process by increasing the shift and the number of mechanisms for mechanized work or the number of performers for manual work. Depending on the period for which the schedule is calculated, and the complexity of the object, there may be several leading processes.

The timing of the remaining processes is tied to the leader. All non-leading processes can be divided into two groups according to the nature of scheduling: 1) running in a thread (as a rule, in equal or multiple rhythm with the leading thread) or 2) running outside the thread.

Parameters of the calculation part of the CP: - labor intensity (labor costs), computer time costs of the leading machines: (machine-bone), the number of machines, the number of shifts and the duration of work can alternately act as an argument or function when compiling the CP, depending on the accepted initial data and prerequisites.

In the first group of processes, the argument is time - the duration of the leading process, and the number of performers is derivative (quotient from the division of labor intensity by duration). This is how plumbing, electrical, carpentry, plastering and other works are designed for the construction of a residential building. Here it remains to bind the start time of one or another specialized flow in relation to the leading one, i.e., to establish how many blocks (floors) should be started the next process with a delay. The solution lies between the minimum, determined by safety considerations, and the maximum, allowed by the established terms of the construction of the facility.

When working with commercial offers, you often come across different estimates, i.e. both in the regulatory framework of TER or FER, and with various types of calculations.

As a rule, the customer wants to understand the true cost of these works, if he is a private person, then the calculations according to the Gosstroy method are advisory, not mandatory.

The estimator who is engaged in checking commercial proposals must know well the “work market” in this region. The cost of work is different everywhere and is very different, for example, in the capital and regions.

This difference is very significant and it is better to calculate the resource method in such situations. The cost of materials in this region according to the consumption rates of the Gosstroy HESN and labor costs (persons / hours) for the production of work. Standard hours are also in the collection of GESN or in estimated prices, and everywhere the labor costs per unit are indicated. measurements. I offer two options for estimates for detailed consideration.

Estimate calculation options

The first option for calculating the estimate

The estimate was made according to the methodology of Gosstroy in the territorial prices of St. Petersburg in the base-index method using indices. The materials are taken from the Stroytsena collection at current prices and are not indexed. Reconstruction coefficients are also applied.

The second option for calculating the estimate

Estimate No. 2 is made at contractual prices. Let's take a closer look at this option. This is not the whole estimate, but only work on the installation of partitions from the plasterboard. By item numbers it is clear that the contractor specifically put them in such an order that everything in the set of prices was not very readable.

The cost of work according to the estimate was 6,500,000 rubles.

At first glance, in estimate No. 2, everything seems to be clear. You can see the cost of work, materials, transportation costs, overhead costs per unit. measurements.

But everything is not as simple as it seems at first glance.

If you look at the resource sheet of estimate No. 1 made in TEP, then all materials are presented in accordance with the standards for this type of work, but without VAT.

The materials accepted in the resource estimate are taken from Stroyzen's collection, which have already been transferred from the wholesale price to the estimate. Estimated price - this is the wholesale price increased from 3 to 6 percent for the delivery of material from the place of purchase to the place of installation, because it is not taken into account in the prices for work, but is taken into account in the material according to the Gosstroy pricing methodology.

Consequently, the cost of materials is 686x1.18 = 810 rubles, and this is not counting the discounts of the contractor who buys material in large quantities from one supplier.

From Estimate No. 2 (contractual estimate), we see that the cost of materials is accepted as rounded 1115 rubles, but there is also Tr. p 15%.

1115 + 15% Tr.r. = 1,283 rubles.

We compare the cost of materials of estimate No. 2 and Estimate No. 1

We compare the cost of materials of estimate No. 2 and Estimation No. 1, it turns out 1,283-810 \u003d 473 rubles, which is much higher than in Estimation No. 1, and for large volumes these are overpaid costs.

Although all materials can be taken much cheaper than in Estimate No. 1 Ter. , because in the collection Stroytseny average prices in the city.

Let's look at the salary

The cost of work according to Estimate No. 2 RUB 1255+ Overhead And Estimated profit 1255+377=1632 rub.

In estimate No. 1 Wages + N.exp. and Estimated profit will be 527 + 529 + 266x1.18 = 1560 rubles.

The difference is small, but at large volumes it is very significant. 1632-1560=72 rub.

But that is not all

Let's carefully analyze the salary in Estimate No. 2

Labor costs according to GESN according to Estimate No. 1 is 3.39 people / hour.

If we take the average prevailing salary in the given region in construction not from official sources, then this is 40,000 rubles.

40,000 rubles / 22/8 \u003d 227.27 and then multiply by 3.39 hours / hour, you get 770.45 rubles and then add 30%, you get 1002 rubles, and the contractor claims 1650 rubles.

The difference will be 648 rubles. All this must be carefully looked at, because these prices are negotiable.

As the saying goes, “one sells and the other buys. The difference in cost between Estimate No. 1 and Estimate No. 2 will be 2,381 -2,914 = 533 rubles. per 1 sq.m.

Estimate No. 1 in the amount of 2381 rubles. is not a panacea. In this region, you can easily negotiate and reduce the cost by 20-25%.

If our calculations and wishes are useful, then we have not wasted our time. Any questions, please write. We will try to resolve these issues.

The development of cost estimates is a mandatory procedure for any major construction project. This is due to the fact that the construction or construction without preliminary calculation of potential costs turns into a real lottery - the process is also unpredictable, and success is just as unlikely. However, the need for a construction estimate today can hardly cause anyone to doubt. Discussions are rather on a different issue: is it necessary to involve specialists in a project who can check the documentary cost of construction for expediency? Today we’ll talk about whether a competent analysis of estimates is so necessary in construction.

Estimated documentation includes:

• explanatory note;
• estimates calculations;
• local estimates;
• object estimates;
• total expense report (summary of costs).

Analysis of estimates. General provisions regarding estimate documentation

The construction estimate is a document that displays the funds necessary for the construction of the building. This document is also being developed during the reconstruction of structures, their capital.

The construction estimate includes a large number of various costs for the implementation of the project, taking into account the services of workers and the purchase or rental of special equipment.

It is usually not possible to determine how correctly and correctly the development of estimate documentation was carried out by an unqualified person. If a citizen can still find out and compare the average market prices for building materials and labor of workers on their own, then consideration of indirect costs usually in this case turns into a meaningless contemplation of a huge number of incomprehensible values ​​and calculations.

In addition, if errors in the estimate documentation were made on purpose, then even direct costs will be scheduled in such a way that an inexperienced person without the necessary qualifications could not detect any problems. Therefore, only a comprehensive analysis of estimates conducted by competent and competent specialists is guaranteed to identify unnecessary and inappropriate costs. .

Recall that the estimate documentation classifies the costs into direct and indirect, and also makes a separate point for the contractor's remuneration. Analysis of estimates involves a thorough study of all these components, both individually and in the aggregate, in a single complex.

Direct costs include:

• purchase or rental of the necessary equipment;
• payment for transport services;
• payment of labor resources (services of workers, experts, specialists);
• the cost of purchasing the necessary building materials, products.

Indirect costs include mainly those items that an ordinary layman would prefer not to encounter once again. Tax, credit and insurance payments - all this is included in the construction cost as indirect costs. Often, a competent analysis of estimates reveals significant distortions of information in this section of the data. This also includes the cost of running the business.

Based on our own long-term practice, we strongly discourage clients from signing an estimate without conducting its preliminary analysis. Construction is, it would seem, a very serious and responsible process, and some customers still prefer to put their signature on any documents without studying the content of the latter.

If errors in the estimate documentation could only be caused by the inattention or incompetence of a conscientious specialist, then a professional analysis of estimates would indeed have a very controversial need. In the end, serious mistakes are rarely made, and they are quite easy to detect. However, a huge number of companies deliberately distort the data presented in the estimate documentation. Taking advantage of the insufficiently high awareness of the customer, who is not required to be familiar with all the small nuances of construction procedures, unscrupulous specialists can purposefully overestimate or, on the contrary, underestimate the cost of construction. The way in which the information will be distorted directly depends on what specific goal the specialists expect to achieve at the current moment.

Analysis of estimates. When can a specialist deliberately underestimate the estimated cost? When to inflate?

At the time of the tender, all potential contractors must develop preliminary cost estimates based on the design documents provided to them.

Then the estimates of all contractors are compared with each other, the most profitable option is selected. Wanting to win the competition at all costs, some organization can artificially underestimate.

This is done quite simply: some of the necessary work and costs are not included in the document at all, and some are simply underestimated relative to their market indicators. As a result, an unscrupulous contractor wins the tender, and then, a little later, the customer discovers that the construction costs much more than expected.

Moreover, a thorough study of the estimate on your own at this stage is important, but ineffective: how does a person without proper experience and relevant qualifications know that some important and expensive procedure was not included in the document?

Timely analysis of estimates, carried out by competent specialists, will not allow an unscrupulous contractor to win the tender.

With an overestimated cost, the situation is simpler and does not require scheduling: some resources may be indicated by an unreasonably high price, which differs very unfavorably from existing market analogues. This is done for quite understandable reasons - to earn more where there is an appropriate potential for that.

It turns out that the analysis of estimates is still necessary?

If we are talking about a large construction project, then the answer will be entirely in the affirmative. The practice of the number of low-quality estimate documents is too disappointing. Often the contractor tries not even to cheat, but to deceive the customer, turning the estimate from an exact document into paper, the real value of which for a particular construction is not higher than the value of a three-page children's fairy tale - the data presented in it does not reflect the real state of affairs on the project.

In order for the construction cost indicated in the documentation to fully correspond to the actual costs, a competent and competent analysis of estimates is required. You can order consideration of the estimate documentation in our expert organization. Our experts will consider all the submitted documents, make a verdict on the appropriateness of each of the items of expenditure indicated in them. In particular, our analysis of estimates regularly reveals:

• incorrect selection of analogue products;
• errors in calculations when determining indirect construction costs (the specialist used outdated or unknown coefficients, operated with controversial and unreliable data regarding the planned cost);
• Deprived of expediency of stretching the terms of construction procedures.

Why is a private analysis of estimates worse than a public one?

The answer is nothing. The analysis of estimates carried out by private organizations is in no way inferior to the examination conducted by state bodies. It also has several clear advantages.

At a minimum, the analysis of estimates is much more thorough and attentive to detail. The customer can be sure that not a single controversial and extra cost item will be missed. The chance that in the future the construction project will have to be suspended due to violation of certain rules, a private analysis of estimates completely excludes.

In terms of timing, everything is also pleasant: a non-state analysis of estimates rarely drags on for at least a month, while its state counterpart can easily drag on for at least a third of a year due to huge queues.

The conclusion of a private and state expert has absolutely the same force, if it is understood that the former has documents confirming his competence. Therefore, private analysis of estimates is no worse than the state one.

Composition and purpose of design and estimate documentation

In the process of investment design, design estimates are developed on the basis of the regulatory framework governing the construction of enterprises and structures.

Design and estimate documentation (or design materials) is a system of documents containing a description and justification of the project, which covers both documents required for the design of capital construction facilities, and additional materials developed by project participants during examination, preparation for implementation and in the process of implementation projects.

The composition, procedure for the development, approval and approval of this documentation is regulated, first of all, by the State Building Regulations (DBN), in particular, such as DBN A.2.2-3-2004 "Composition, procedure for the development, approval and approval of project documentation for construction", DBN D.1.1-7-2000 "Rules for determining the cost of design and survey work for construction carried out on the territory of Ukraine" and others.

The composition of the design and estimate documentation depends on the complexity of the designed objects (Table 2. 1).

In the design and estimate documentation, the technical and economic characteristics of the project are detailed and specified.

Table 2.1

Composition and purpose of design and estimate documentation depending on the category of complexity of objects

Component of design and estimate documentation	Characteristics of objects by category of complexity
The working draft is developed to determine specific urban planning, architectural, artistic, environmental, technical, technological solutions of the object, their technical and economic indicators, the performance of construction and installation works, working drawings and determine their estimated cost. It consists of two parts - approved (as part of an explanatory note, which is subject to agreement, examination and approval) and working drawings.	Technically simple objects, as well as objects using projects of mass and repeated use of category I
The preliminary design defines the fundamental requirements for urban planning, architectural, environmental, functional and other solutions of the object in order to confirm the possibility of its creation as a civil structure.	Civil facilities using projects of mass and repeated use of category II, as well as objects using projects of mass and repeated use of category III - are developed at the first stage of design. Objects of technically complex civil purpose in accordance with urban planning, architectural, artistic and environmental requirements of engineering support of category IV, as well as technically complex civil facilities for the introduction of new building technologies, structures and materials of category V - are developed at the first stage of design and refined at the second stage. Objects of technically complex production purposes according to urban planning, architectural, artistic and environmental requirements of engineering support of the IV category, as well as objects of technically complex production purposes for the introduction of new building technologies, structures and materials of the V category - are being developed at the second stage of design.

Continuation of the table. 2.1-1

Working documentation is developed for construction and installation works and contains working drawings, initial requirements for the development of design documentation for equipment, specifications for equipment, products and materials, dimensional drawings, estimate documentation, etc.	Objects using projects of mass and repeated use of II and III categories - are being developed at the second stage of design. Objects technically complex in terms of urban planning, architectural, artistic and environmental requirements of engineering support of the IV category, as well as objects technically complex in terms of the introduction of new building technologies, structures and materials of the V category - are being developed at the third stage of design.

Today, a construction audit is an effective tool for monitoring the results of the work of contractors - both at the stage of designing and performing construction and installation works, and in the process of commissioning completed construction projects. The examination carried out as part of a construction audit allows the customer to obtain a qualified opinion on the quality of the work performed, the compliance of the size of the actual construction costs with the costs declared according to the primary documents. In addition, a construction audit allows minimizing the risks of poor-quality work, allowing timely detection of construction defects, assessing the damage caused and reasonably holding the contractors accountable.

Services:

- Analysis of design estimates

Analysis of design estimates is carried out, as a rule, at the design stage of construction projects. A timely detailed analysis of construction projects and estimates allows you to determine the compliance of the declared parameters of the object with the requirements of building codes and regulations (SNiP), verify the correctness of the application of prices for building materials and the feasibility of the work provided for in the estimates, and evaluate the real cost of the construction object. A detailed engineering and technical analysis at the design stage makes it possible to obtain a qualified opinion on the possibility of constructing an object as a whole with the technical characteristics required by the customer.

- Examination of objects of unfinished construction. Examination of objects put into operation

This type of expertise is carried out in relation to construction objects at all stages of construction and installation works until the moment the object is put into operation, as well as in relation to existing objects, regardless of the terms of their operation.

The examination provides for the following types of work:

examination of design and estimate documentation;
examination of actually performed external and hidden construction and installation works in order to determine their volume, cost, compliance of the materials used with those stated in the estimates;
analysis of the compliance of the estimated cost of construction work with the actual costs of building the facility;
verification of compliance of the quality of work performed with current standards, building codes and regulations (SNiP, GOST) and other regulatory documents;
documentation of revealed violations and determination in value terms of the amount of damage caused (direct and indirect);
recommendations to eliminate the identified deficiencies.

- Analysis of the compliance of the declared cost of construction work with the actual costs of building facilities

This type of examination is carried out in order to control the compliance of data on the actual costs of construction and installation works with the estimates for the construction of the facility, control over the compliance of the actual consumption rates of materials with the provided estimated standards, the correctness of the applied prices and calculations of the actual cost of work, as well as the compliance of the nomenclature of the applied materials that are provided for by the technical documentation for construction.

Control over the actual costs of the construction of the facility is carried out both on the basis of primary documents (contracts, acts of work performed, estimates, invoices, etc.), and on the basis of full-scale studies of construction objects using special methods for assessing the actual costs of materials and labor costs.

In addition, at the request of the customer, an audit check of the compliance of accounting data for accounting for construction costs and their compliance with data from primary documents is carried out.

This type of expertise can be used by the customer organization both in relations with contractors and to ensure internal control over the performance of construction work in an economic way.

- Quality control of construction works

Quality control of construction work is a mandatory procedure in the process of acceptance by the customer of the completed stages of construction work and the acceptance of the construction object as a whole.

During the control procedures, the actual quality of the work performed is determined, compliance with the requirements of state standards, building codes and regulations (GOST, SNiP) is checked. The actual readiness of the construction object is determined. The procedure for issuing reporting documentation on the work performed is checked, its compliance with the requirements of state standards, the determination of its completeness and sufficiency to determine the volume and cost of the work performed.

All shortcomings, defects and deviations from the project, identified as a result of the examination, are documented and systematized in the report on the results of the examination. The amount of costs for correcting imperfections and defects is determined, as well as the amount of damage caused (in the case of irreparable defects and deviations from the project).

Quality control also includes an assessment of the internal construction control system, in particular, systematic verification of the compliance of the volume, cost, methods, technology and quality of construction and installation works with approved projects and estimates, building codes and rules, standards and other legal documents.
