The composition of the estimate documentation and the procedure for its development. The procedure for the development of estimate documentation for construction The composition of the estimate documentation the sequence of its preparation
Estimate - financial document, which determines the estimated cost of all types of work.
Part budget documentation may include:
1) local estimates (estimate calculations) for certain types of work that must be performed on this object;
2) object estimates (estimate calculations) for the object as a whole, where data from local estimates are combined;
3) estimates for certain types of costs;
4) summary estimates; 5) summaries of costs.
Local estimates for certain types of construction and installation works, as well as for the cost of equipment, are based on the following data:
parameters of buildings and structures, their parts and structural elements adopted in design decisions;
· volumes of works given in the statements of construction and installation works;
nomenclature and quantity of equipment adopted in custom specifications, statements and other design materials;
· current estimated standards and indicators for types of work, structural elements, as well as market and regulated prices and tariffs for industrial products and services.
Local estimates are developed for:
buildings and structures, construction and internal plumbing work, electric lighting, electric power plants, purchase and installation of technological equipment and instrumentation;
public works, vertical layout, arrangement of engineering networks, landscaping, etc.
When designing complex buildings and structures, developing technical documentation several design organizations, as well as during the formation estimated cost start-up complexes allow the preparation of two or more local estimates (estimates) for the same type of work. In local estimates, data are grouped by individual structural elements of the building (structure), types of work and devices. The order of grouping should correspond to the technological sequence of work and take into account the specifics of individual types of construction. The local estimate may contain separate sections for construction and internal plumbing work, equipment installation, etc.
The cost determined by local estimates includes direct costs, overheads and estimated profit. Direct costs take into account the cost of wages for workers, materials, products, structures and operation of construction machines.
Overhead costs include the costs of contractors associated with the creation general conditions production, its maintenance, organization and management.
Estimated profit - the amount of funds necessary to reimburse certain expenses of contractors for the development of production, the social sphere and material incentives.
It acts as a normative part of the cost of construction products and does not apply to the cost of work.
Object estimates (calculations) are developed for the object as a whole based on the indicators of local estimates with a grouping of work and costs in the appropriate columns - the estimated cost of construction and installation work, equipment and other works with the subsequent addition of limited and other costs.
Estimates are made in a single price level in the base or in the current (forecast) options. On the basis of object estimates, settlements for the work performed between the customer and the contractor are carried out.
Estimated calculations for certain types of costs are necessary for those cases when it is necessary to establish for the construction site as a whole the amount of funds required to cover costs not taken into account estimated standards. Such calculations are made in the same manner and in the same form as local estimates.
To determine the estimated cost of the designed enterprises, buildings and structures, estimate documentation is compiled. Its composition allows you to determine the estimated cost of various types of construction products: construction and installation works, construction projects, construction in general and, if necessary, their constituent start-up complexes and construction phases.
The procedure for the development of estimate documentation is established by the Instruction on the procedure for development, approval, approval and composition project documentation for the construction of enterprises, buildings and structures.
With a two-stage design, the full composition of the estimate documentation is developed at the first stage - a feasibility study (project) in the form of estimates and can be specified at the stage of working documentation by drawing up local and object estimates, if this is provided for by the contract for design work. At the stage of the working draft, local and object estimates and a summary estimate of the cost of construction are compiled.
8. The procedure for preparing design estimates.
8.1. General provisions
In accordance with Art. 48 Urban Planning Code RF project documentation is a documentation containing materials in text form and in the form of maps (diagrams) and defining architectural, functional, technological, constructive and engineering solutions to ensure the construction, reconstruction of facilities capital construction, their parts, overhaul, if during its implementation the structural and other characteristics of the reliability and safety of capital construction objects are affected.
Types of work on the preparation of project documentation that affect the safety of capital construction facilities should be carried out only by individual entrepreneurs or legal entities that have issued self-regulatory organization certificates of admission to such types of work. Other types of work on the preparation of project documentation can be performed by any individuals or legal entities.

In accordance with the "Instruction on the procedure for the development, approval, approval and composition of project documentation for the construction of enterprises, buildings and structures" (SNiP 11–01–95), the estimate documentation is integral part project for the construction of construction products and is included in the project in the form separate section.
A project is a complex of engineering solutions, drawn up in the form of a set of technical and economic documents, calculations that make it possible to judge the feasibility and quality of a future building or structure. It includes explanatory note, drawings and estimates.
Design work is carried out under an agreement with the customer by design, design and construction organizations and other legal and individuals licensed to design.
In order to reduce the time for designing and building real estate in St. Petersburg and to streamline the activities of bodies that issue initial data for design, approval (examination) of projects, and issuance of building permits, the Government of St. Petersburg, by Resolution No. 1322 of July 27, 2004, adopted "Procedure for design preparation of capital construction in St. Petersburg".
Design documentation for the construction of facilities is developed on the basis of initial permits, architectural and planning tasks (APZ) of the Committee for Urban Planning and Architecture (KGA) of the region, design tasks and other initial data.
The KGA issues an APL for design at the request of the customer (investor) within a month from the date of registration of the application.
The main documents governing the relationship of the parties in the design are treaty concluded by the customer with the designer, and design assignment. The recommended composition and content of the design assignment are given in Appendix 16. The main requirements for the assignment for the development of a development project are set out in SNiP 11-04-2003 "Instructions on the procedure for the development, coordination, examination and approval of urban planning documentation." The design brief is subject to approval by the CAC.
Together with the approved design task, the customer transfers to the designer the initial data necessary for designing in accordance with the contract.
Depending on the responsibility of buildings and structures, three categories of complexity of objects and the stages of their design are established (design and working documentation - design in two stages; working design - design in one stage).
Based on the agreed and approved project, working documentation is being developed.
In case of one-stage design, the approved part of the working draft is subject to approval.
Government services, industry departments and other interested organizations provide specifications and requirements for the design of facilities at the request of the customer within a period of not more than 15 days from the date of registration of the application, part of which is used in the pre-project preparation (stage) of the construction of the facility - feasibility study (feasibility study) or feasibility study (feasibility study) of the construction cost to determine economic feasibility design and construction.
The project and the approved part of the working draft for the construction of housing and civil facilities consist of the following sections:
- General explanatory note.
- architectural solutions.
- Constructive decisions.
- Technological solutions.
- Engineering and equipment solutions.
- Environmental protection.
- Engineering and technical measures of the civil defense emergency.
- Organization of construction.
- Estimated documentation.
- Technological regulations for handling construction waste.
The Government of the Russian Federation, by Decree No. 1008 of December 27, 2000, approved the “Regulations on conducting state expertise and approving urban planning, pre-project and project documentation in the Russian Federation”, according to which project documentation is subject to state expertise before its approval, regardless of funding sources and ownership of objects.
Before approval and examination, project documentation is subject to mandatory submission for consideration:
- Chief Architect of St. Petersburg;
- in KGIOP;
- to the Center for State Sanitary and Epidemiological Surveillance of St. Petersburg (TSGSEN);
- to the Office of the State Road Safety Inspectorate (GIBDD);
- to the Department of Gardening and Park Management (USPH).
- North-Western branch of the state expertise of projects of the Ministry of Emergency Situations of the Russian Federation (for the relevant facilities);
- State Service building supervision and expertise in accordance with the Decree of the Government of St. Petersburg dated October 26, 2004 No. 1747;
- specialized state expert organizations.
There are sectoral expert divisions in the relevant ministries and departments.
The main purpose of the examination is to control compliance with state norms and rules. The duration of the state and specialized examinations is established by the contract, but should not exceed 30 days. For particularly complex objects, the duration of the examination can be increased, but not more than 10 days.
Based on the results of the examination, a conclusion is drawn up, which is a mandatory document for execution by customers, design, contracting and other interested organizations.
Work on the examination of pre-project and project documentation is paid by the customer with the attribution of these costs to chapter 12 of the consolidated estimate calculation of the cost of construction according to the standards from the cost of design and survey work(columns 7 and 8).
Requirements for the design and construction of buildings and structures are given in building codes and regulations (SNiP), consisting of four parts, including the relevant collections:
- Part 1. Building materials, products, structures and equipment.
- Part 2."Construction Design Standards".
- Part 3"Rules for the production and acceptance of construction work."
Approval of project documentation for the construction of facilities, depending on the sources of financing, is carried out:
- in case of construction at the expense of the budget of St. Petersburg - by the relevant executive bodies of state power of St. Petersburg (after the state examination of the consolidated estimate calculation made as part of the working documentation for the construction of the facility);
- during construction due to own funds customer (investor), including borrowed funds, - directly by the customer (investor).
Working drawings are the basis for compiling local and summary statements of resource requirements, developing local and object estimates, which are also part of the working documentation.
The section "Estimate documentation" contains local and object estimates, estimates for certain types of costs, including survey and design work, a summary estimate of the cost of construction and, if necessary, a summary of costs. Based on the estimated cost of construction, customers and contractors, based on the results of contract bidding, form a contractual price for construction products.
The contract price can be final or open, specified under the terms of the contract during construction.
Determination of the cost of construction products, as a rule, is carried out in two stages.
1. As part of a feasibility study at the pre-project stage of project development. At this stage, it is recommended to use aggregated indicators of the base cost or data from analogue projects. In this case, the reserve of funds for unforeseen work and costs and value added tax are taken into account.
2. As part of the design and estimate documentation, the estimated cost of construction is determined. The basis for determining the cost of construction is the project, working documentation and the corresponding estimated and regulatory framework.
Decree of the Government of St. Petersburg dated July 27, 2004 No. 1322 recommends the "Combined schedule for the design and construction of the facility."
The duration of the design according to the recommended schedule from the moment of the Government's decision and the beginning of the execution of the CAA APL until the completion of the development of working documentation, including the estimate, is almost 14 months. The period of construction from the allotment of the site to the completion of landscaping and landscaping is on average 22 months.
AT developed countries all preparatory work takes 1 year (first, land is acquired, which becomes a pledge).
Design costs in Russia amount to 3-6% of the cost of construction, abroad (in developed countries) - 12%.

Development of design and estimate documentation includes the following steps:
1. Justification of investments and issuance of design assignments;
2. Competition of scientific and design organizations (design institutes, construction organizations, computer centers) and conclusion of an agreement with the winner;
3. Development of a feasibility study for the construction of facilities, including sections performed by other organizations
4. Selection of the territory (area, routes) and drawing up a selection act;
5. Development of a different design and estimate documentation.
DED includes the development of technical and technological documents (technical project for the construction of a well), organizational and managerial (substantiation of the project management structure) and financial and economic (business plan, estimates) nature.
One of the most important documents for which costs are planned is estimate. The estimated cost is the price of the project.
There are 3 types of estimates:
Local - by type of work (SMR, drilling, fastening, testing);
· Objective – for each structure (estimates for the construction of wells or a group of similar wells);
Consolidated estimates - for the whole project
The summary estimate consists of 12 sections:
1) Preparatory work
2) Main construction objects;
3) Service facilities;
4) Energy facilities;
5) Communication and transport facilities;
6) Objects of heat, water, and gas supply;
7) Temporary buildings and structures;
8) Objects of improvement;
9) Other objects;
11) Training of personnel of the future enterprise;
12) Design and survey work.
Estimated cost of the project:
C cm \u003d C pr + C c + C o + C m + C p + C p
C pr - the cost of preparatory work;
C c - the cost of construction of facilities;
C o - the cost of equipment, materials, etc.;
C m - the cost of equipment installation;
C p - the cost of other objects;
C p - reserve for unforeseen expenses.
Cost planning occurs in three stages:
1. A list of works is formed on the basis of the calendar plan (year, quarter, month);
2. Based on local estimates, the cost of work is determined;
3. Costs are calculated by directions or economic elements costs (raw materials (not included in the project), basic materials; auxiliary materials; salary with deductions; energy from outside; fuel from outside; depreciation deductions, others).
Then an integral field development curve is built:
1 - Early start or accelerated pace of development capital investments;
2 - Late start - slow pace of development of capital investments;
3 - the average rate of development of capital investments.
Then the estimated cost of the work scheduled for execution for a certain period of time is determined:
The sum of the areas of the figures is the estimated cost.
After that, the costs are distributed over time for each type of work:
Estimated calculations serve as the basis for the preparation of the project budget. Flow control budget funds carried out by a special group created by the customer. This group can forecast costs for subsequent calendar periods of the project.
Estimated documentation is an obligatory part of the project for the construction of structures, buildings, enterprises and is included in it as a separate section. Design work is carried out on the basis of an agreement with the customer legal entities and individuals licensed for this activity. Consider briefly composition and procedure for the development of design and estimate documentation.
General information
According to the procedure for the development of design and estimate documentation, under the contract, the customer must transfer the terms of reference to the contractor. It indicates the terms of the construction of the object, its parameters, the stages of design and other initial information necessary for the high-quality performance of the work. The task can be prepared by the contractor himself on behalf of the customer.
In accordance with Art. 761 of the Civil Code, the designer is responsible for the timeliness of development and the quality of documentation.
staging
The customer chooses the contractor, as a rule, on a competitive basis. Development of design estimates can be carried out in one or two stages. The first option is used for technically simple objects, standard buildings and structures, objects of technical re-equipment.
Documentation for more complex objects is carried out in 2 stages. On the first one, a project is created, on the second - working documentation. The first consists, in turn, of two parts:
- Architectural and construction drawings (including work organization, engineering equipment, etc.).
- Estimates and technical and economic parameters.
working documentation
It is developed after the approval of the project. The working documentation includes a set of drawings, in accordance with which the drawings are made as the basis for. They are also used in the preparation of summary and local statements of resource requirements.
The composition and procedure for the development of estimate documentation (general rules)
To determine the cost of construction work, it is recommended to make calculations:
- object and local;
- for certain types of expenses;
- construction/repair costs.
These calculations are included in the project. If necessary, a summary of costs is compiled. As part of the working documentation, there are object and local estimates. The latter act as primary documents.
Local estimates are developed for individual works and expenses in accordance with the volumes determined during the preparation of the project and working documentation (drawings). They are also formed in cases where the costs and scope of work are subject to clarification.
In object estimates, information from local documents for the entire object as a whole is summarized. They act as the basis for settlements between contractors and the customer.
Calculations for certain types of costs necessary to determine the budget limit (if these costs are not taken into account in the standards) are compiled according to the rules provided for the formation of local estimates.
According to the consolidated documents, the volume of expenses for the entire construction as a whole is determined. These calculations include information on object estimates and calculations for individual types of costs.
A summary of expenses is a document that determines the cost of construction when documentation is developed for objects:
- industrial purpose;
- ancillary agricultural and consumer services for citizens;
- housing and civil purposes;
- land urban passenger transport and a number of others.
Additionally
If the project provides for the commissioning of a structure (institution, enterprise) by start-up complexes, it is carried out at the cost of the facilities included in these complexes. If during the construction process environmental protection measures are assumed, a statement of their cost is formed.
Unit rates
At development of estimate documentation for construction territorial or federal and FER are used, respectively). The former are used in the preparation of settlements for the work performed for all construction sites and facilities, regardless of the sources of their financing, including if the costs are covered by funds federal budget. FER are used only when there are no TEP collections in the region or there are, but not all works. In the latter case, the simultaneous use of federal and territorial collections is allowed.
Work grouping
It is carried out in sections on the structural elements of the structure, types of devices and works. The order of location should correspond to the sequence of construction activities, as well as the specialization of the contractor. At development of estimate documentation local type of work related to the ground and underground parts of the facility are separated into separate sections.
Calculation methods
It is carried out using the following methods:
- Resource. It provides for calculation in forecast / current tariffs and prices of expenditure items by resource type.
- Resource index. It involves the use of the resource method and indexes on resources.
- Basis-index. This method involves the use of a system of forecast and current indices relative to the estimated cost established in the basic price level on a one-to-one basis.
- Basic-compensatory. It combines the basis method and the determination of compensation for additional expenses contractor.
Development of estimate documentation can also be carried out on the basis of an information base on structures and buildings similar to those being designed.
Types of jobs
Development of estimate documentation produced on:
- Construction works (including special ones), internal sanitary measures, electric lighting, purchase and installation of power units, other equipment, control of measuring devices, low-current devices, automation, inventory, furniture, etc. These calculations are made for structures and buildings.
- Vertical layout, laying engineering communications, roads, ways, landscaping, installation of small architectural forms, etc. Calculations are made for general site works.
Sections
When developing budget documentation for construction works cost is calculated:
- Earthworks.
- Foundations and walls of the underground part.
- frame.
- Stan.
- Overlappings.
- Partitions.
- Floors and grounds.
- Finishing work.
- Other construction activities (porch construction, etc.).
When drawing up an estimate for special work, it includes sections:
- "Canals and pits".
- "Special Grounds".
- "Protective chemical coatings".
- "Insulation and lining", etc.
The estimate for internal sanitary and technical work includes the following sections:
- "Water pipes".
- "Heating".
- "Sewerage".
- "Air conditioning and ventilation", etc.
Calculations for the installation of equipment consist of sections:
- "Technological equipment".
- "Metal structures".
- pipelines, etc.
Basis-index method
Considering procedure for developing budget documentation, it is necessary to dwell separately on the most common method of compiling local calculations. It is the basis-index method. It is a normative-calculative method for determining the cost based on TEP. The value calculated in basic prices is translated into current prices using indices.
Recalculation can be made by applying coefficients to:
- Items of direct expenses. These include, in particular, items on the cost of paying employees, operating special equipment, and materials.
- The consolidated estimated cost, calculated in prices and according to the norms of the base period.
The indices are divided into groups according to the types of work and construction.
resource method
In the early 90s. it was recommended as the most accurate way to calculate inflation. For its use, first of all, a local statement is compiled. It defines the production resources necessary to perform the work:
- the number of workers;
- operating time of special equipment;
- consumption of products, materials, structures (in physical units - cubic meter, tons, square meters etc.).
When determining resource indicators, the following can be used:
- Design materials, information on labor costs and other information contained in the OS project (for the organization of construction) or work execution (PPR).
- Collections of standard consumption of materials for the main types of work (assembly, special, construction).
- Estimate-normative base. It includes collections of GESN-2001. In case of their absence, branded (FSN), industry (OSN), territorial (TSN) collections are used.
The calculation of the estimated cost is carried out by evaluating certain types resources in forecast/current prices.
Object estimates
They are formed using current prices. The calculation is made by summing up the final indicators of local estimates with a grouping of expenses and work in columns:
- "Construction works".
- "Equipment, stock, furniture".
- "Mounting".
- "Other expenses".
When determining the total cost in the object estimate, limited costs can be used. Their standards are set as a percentage of the cost of work on:
- Construction of temporary facilities.
- Rise in the cost of work in the winter.
In the object calculation in the "Result", line by line, the values of the unit cost per design meter of the structure per 1 cubic meter are given. m of construction volume, 1 sq. m total area, 1 m length of communication systems, etc.
After the "Total", the amounts of returns are reflected for reference (15% of the cost of temporary objects, summed up with the cost of return materials, which is provided for in local calculations).
Information base on analogues
An object under construction or already constructed, the estimates for which are formed according to working drawings, should act as a similar one. When choosing the characteristics of the designed structure / building and its analogue, they should correspond as much as possible to each other according to the design and planning scheme, functional / production and technological purpose.
Reserve
The results of the estimate are summed up for each chapter, as well as for the sum of chapters 1-7, 1-8, 1-9 and 1-12. On a separate line at the end, a reserve amount is provided for unforeseen expenses and work. It is calculated from the total cost. For construction carried out on capital investments financed by the budget, the amount of the reserve cannot be more than 3% for production facilities and 2% for structures social sphere.
Conclusion
The procedure for the development and approval of design and estimate documentation is determined by Gosstroy. The basic rules are given in Decree No. 18-41 of 29 Oct. 1993
In accordance with its provisions, design estimates for construction carried out at the expense of the republican budget are approved by Gosstroy. The rules for coordination may be established by the said body, together with the departments and ministries concerned, by provisions on the division of powers.
For construction carried out at the expense of the regional budget, it is approved by the relevant state administration bodies or in the manner prescribed by them.
Projects for facilities built with own, borrowed, borrowed funds from investors (including foreign ones) are agreed directly with customers.
