Design in two stages. Composition of the documentation

Design is carried out in two or one stage.

Essence two-stage design is that the documentation necessary for construction is not drawn up immediately, but in stages: at the first stage (“Stage I”), decisions are made on general fundamental issues, then such decisions are comprehensively assessed, adjusted, approved, and only after all identified deficiencies have been eliminated, a detailed working document is drawn up documentation for construction. The advantage of such a system is to minimize the costs of processing design documentation in the event of unsuccessful overall solutions.

Essence one-stage design the fact that project documentation is prepared immediately in full and contains solutions to all general and specific issues. This is convenient for small amounts of design work.

In practice, these schemes are implemented as follows.

With two-stage design, the work is divided into 2 stages:

• stage "Project" (P)
• stage "Working documentation" (DD)

At the “Project” stage, basic architectural, planning and design decisions (including the general plan), decisions on engineering equipment, and networks are made without detailing. When designing environmental facilities, at this stage, fundamental decisions are made regarding the choice of the type of structure, its location, basic design solutions, construction method, etc. For industrial enterprises, schematic diagrams of technological processes are selected, general issues of management and labor protection are resolved. Summary estimates are carried out, issues of construction organization are resolved. A mandatory element of the project is the environmental section.

To draw up the “Project”, special engineering surveys are ordered and carried out. Such surveys are carried out in a reduced volume, but they should allow drawing conclusions about the suitability of the site, the preference of one or another type of foundation (shallow, pile, deep supports, etc.), i.e. allow the solution of general fundamental issues.

All this documentation is sent to the state examination, which gives its comments and general assessment of the project. After the designer has eliminated the identified deficiencies, the project is reviewed and approved (or rejected) by local executive authorities or other approving authority. The approval process depends on the source of funding. If construction is carried out at the expense of budgetary funds, the approving authority is a state body. If it is financed by a specific enterprise, foundation or individual, the approving authority is the customer or investor himself.

After approval of the “Project”, the second stage of design “detailed documentation” is carried out. At this stage, decisions made at the “Project” stage are clarified and detailed, working drawings, local estimates and other documentation necessary for construction and installation work are drawn up. To complete this design stage, detailed engineering surveys are ordered and carried out. They must contain complete information to resolve all particular issues and draw up working drawings that do not require subsequent adjustments.

“Working documentation” is those drawings and text material that is used directly at the construction site (documentation from the “Project” stage, as a rule, is not transferred to builders).

At one-stage design documentation called the “Working Design” (DP) is drawn up; it must also be subject to state examination and approval. In this case, not all documentation is approved, but its most important part (the so-called “approved part of the working draft”).

The main design method in the Russian Federation is two-stage design. Single-stage design is used only for simple objects or for linking projects of mass or repeated use.

One-stage design(detailed design including the approved part and working documentation) - for objects of III-I categories of complexity, as well as for objects built according to standard and reused designs.

Two-stage design(project, working documentation) - for objects of V, IV categories of complexity and for objects of III category of complexity for individual projects.

Three-stage design(pre-project proposal, project, working documentation) - for objects of V, IV categories of complexity and for objects of III category of complexity for individual projects, with an insufficient list of initial permitting documentation.

The design of each construction project consists of stages. Depending on the decision of the customer (developer) and the requirements of urban planning regulations, it carries out design work in one, two or three stages.

Design stages are divided into:

• Project documentation
• Working documentation
• Working draft

Sketch Design (Architectural and urban planning appearance of a capital construction project)

It is a stage of pre-project preparation during which the feasibility of design and construction work is determined and agreed upon with the customer and architectural departments of the city, district, region... (galaarchitecture, etc.). During it, a detailed study of the parameters of the planned object is carried out before a decision is made regarding all sections including design.

The purpose of the preliminary design is to justify the location of the object, determine its investment attractiveness, visualize the appearance and layout, determine the possibilities of constructing the object or its reconstruction, taking into account a number of aspects of a social, economic, historical, cultural, urban planning, sanitary and hygienic and environmental nature.

The preliminary design includes:

• Explanatory note
• Situation plan with areas adjacent to the facility
• General plan (site diagram)
• Floor plans with explications of premises
• Sections describing the “pies” and structural elements
• Facades, developments and fragments of facades
• Color and volumetric design of facades
• Photomontage of an existing object
• Visualization in 3D

Project documentation

The stage of development of design documentation for the construction of facilities and reconstructions, requiring approval by expert review. Developed in accordance with state standards.

The composition of project documentation is regulated by 87 paragraphs and includes:

This is all in the “Communication Networks” section

The documentation developed at the “Project” stage serves as the basis for approval, obtaining a construction permit and subsequent development of “Working Documentation”. Coordinated with the examination bodies.

Working documentation

Working documentation is the detailing of design documentation and its preparation for construction and installation work, including all the components, parts, statements, specifications necessary for the work.

The composition is regulated by state standards and is specified by the customer and the project developer in the contract. For particularly complex objects, two design stages are provided: design and working. Working documentation is developed on the basis of decisions made after approval of the project documentation. If the load-bearing structures of buildings are affected, the design documentation is subject to state examination.

Working draft

A working project is a one-stage design that reduces the development time by 1.5-2 times, reducing the cost of creating a project by 30%. As part of it, in some cases, when working with objects of medium complexity, it is allowed to develop solutions within the scope of the Project with subsequent refinement of working drawings. The composition of the documentation, depending on the customer’s requirements, may be reduced or increased.

The list of initial data for project development includes:

• Urban planning plan of the land plot (GPZU)
• Title documents for the land plot
• Results of engineering surveys (geodetic, geological, environmental...)
• Technical conditions for connection to energy supply networks (electricity, heat, water supply, sewerage, communications, gas...)

In each specific project, the list of initial data may differ and is determined at the stage of consideration of the designed object.

Project documentation must be coordinated with the examination and other interested supervisory authorities.

To get the job done quickly and efficiently, you should contact highly qualified professionals.

At the moment there are several, or to be more precise, two. They are designated as PD and RD, and stand for design and working documentation. If we compare the cost, it is distributed as a percentage: 40% and 60%. At the moment when PD is present at the design stage, it is mainly used for submission to architectural authorities. You can also obtain a permit for construction work, undergo an examination and much more. Detailed documentation of the RD is created at the stage when installation work begins. Based on them, you can create a package of documents for the tender or draw up an estimate.

Characteristics of the PD stage

It must be developed in accordance with GOST; it is subject to a number of requirements related to design and development. All ideas that arise during the work on the project should be displayed on the drawings. All projects are implemented by engineers, who then group all the developments and combine them into one whole.

Work at the PD design stage should be coordinated into general data with the exception of drawings. At the moment the customer submits an application for the work, it is not necessary to develop the entire complex; you can work only on what is required at a particular point in time.

All project documentation must be completed in accordance with what is determined at the legislative level. There are 12 volumes in total. They contain all the information, from the preparation of explanatory notes to construction estimates and other documentation required by law. Of the entire series, information is described in more detail for volume 5, which includes several editions. The books contain detailed equipment information for engineers.

The design and configuration stage of the PD takes a lot of time and effort. Since it is this that is the main one in the development of the future structure. The preparation of documentation should be carried out by qualified specialists with experience.

Characteristics of the RD stage

After the project documentation has been approved, it is worth moving on to full detail, paying attention to all the little things and nuances. This function is performed at the stage of working documentation.

All documentation is prepared in accordance with GOST. The RD includes the development of documents for installation work. Working documents consist mainly of drawings, which are combined depending on their purpose. Based on the submitted documents, a work schedule, estimates and other documentation that the developer will need during the work process are drawn up. There can be any number of drawings, but they should be considered as a whole. All drawings are numbered and signed in advance by the specialist who is responsible for their development.

What are the stages in the construction process?

In 2008, a regulation came into force on the basis of which design stages in construction are not provided. Instead of stages, working and design documents were introduced: PD and RD. But, despite this, there is an option when both types of documentation are developed simultaneously. In this case, we can talk about design being carried out in one stage. If working documents are drawn up after the project has already been approved, then we can talk about two stages of design in construction.

Projects for large facilities are being developed in two stages. First of all, the project is developed and only after that the drawings. Small projects can be developed in one stage. But in this case, it is worth considering that the structure should be standard and not cause any particular difficulties.

Stages used in design

At the moment when the customer needs to develop a project, when contacting the company it is necessary to know which stage is required. For the lightest projects, activities are carried out in one stage of design and development. For difficult jobs there may be two. Particularly complex projects often require the use of three stages.

For example, if a project is being developed for the electrical supply of a residential building, then one stage is needed, if the building is administrative - two, for factories and large supermarkets there may be three. The cost of developing each stage can vary greatly and depends entirely on the state level of prices that are set for construction work.

The main design stages include:

1. Feasibility study - technical and economic justification.
2. FER - technical and economic calculations.
3. EP - sketch of projects
4. P - project.
5. RP - working draft.
6. R - working documents.

Characteristics of stages in the design process

• Feasibility study and fuel and energy assessment. Developed according to customer's order. Designed for objects that have a production, transport or engineering purpose and need to make an informed decision on construction work. FER is used for simple objects with industrial purposes. Compared to the feasibility study, the work is completed in a short time.
• EP. Development is carried out on the basis of an order, when the customer needs to determine a number of requirements for an architectural, urban planning or other object. To justify the decision made, it is necessary to make calculations for all design solutions, and also prepare an estimate and engineering diagrams for the facility.
• P. The project begins to be developed based on the building, initial data and approval of the project, which is carried out in three stages. The information in the project is presented clearly and concisely.

• RP. This stage of documentation design is suitable for simple objects and for those buildings that are planned to be reused. The RP mainly consists of several parts, which include approved and working documents.
• R. Development is carried out in accordance with the approved data at the previous stage. After the project is approved by the customer, working documents begin to be developed by the design author or another designer. Another designer can begin work only if the copyright of the project is respected.

What stages are intended for object design?

Stages of object design are distinguished depending on the level of complexity. There are 5 types in total:

1. Objects that have 1st and 2nd complexity categories are performed:

• in one stage using a working draft;
• in two stages using a sketch project.

2. Objects having the 3rd category of complexity are carried out in two stages: design and working documentation.

3. For objects with categories 4 and 5 of complexity, three stages are provided:

• ES for non-industrial buildings and feasibility studies;
• design development;
• work documents.

One-step design

At the moment when one stage of designing a technical object is envisaged, decisions are made together with the process of creating working documents. All results that will be achieved during the implementation of the work must be reflected in the working draft. Simultaneously with this work, solutions must be found for all other issues.

The information part in the project that is particularly significant is suitable for approval. Documents requiring approval are sent to expert companies, where they will be agreed upon. The necessary drawings for the work must be prepared before the result arrives from the expert company.

This scheme has a number of advantages. For example, the time allotted for design work is reduced several times, which makes it possible to almost halve the cost of the work provided. But in this case, we cannot exclude the fact that the project may require some adjustments. Therefore, it is more expedient to use this scheme in those moments when the designed buildings are standard or are being rebuilt.

Design carried out in two stages

There are also two stages in the design process. All work in this case can be divided into two stages. At the first stage, solutions for the future project are developed, and at the second stage, all working documents are generated. When developing a project, general issues are considered and resolved. After a set of all documents for the project has been generated, it is sent for examination, which is carried out by government or non-government agencies. If experts receive any recommendations related to making adjustments, then changes are made to the project based on this.

Once the experts agree on the project and make the necessary amendments, you can begin to develop the drawings necessary for the work. They will be used in the future during installation work. If the project is complex, then before developing decisions regarding the project, a pre-project solution is drawn up. This method allows you to avoid repeated changes to drawings; it guarantees a high-quality project that meets all requirements, documents and technical specifications.

What do project documents consist of?

Let's consider the design stages and the composition of the design documentation. In this case, everything is clear about the stages; they were discussed above. Their main difference lies in the sequence of decisions made. The composition of the documents depends on how many stages were used in the work process. The entire composition of project documents is approved at the legislative level. There are 11 main sections in total:

1. Drawing up an explanatory note. In this case, a document is presented that describes and explains all the decisions made during the work process.
2. A master plan is used to draw up a diagram of a plot of land that is allocated for construction work.
3. In order to visually see the future building and understand how it will be arranged and function in the future, an architectural solution is used.
4. All load-bearing walls of the building must be designed, for this purpose constructive solutions are provided.
5. Also, the package of documents should include information about communication systems: gas pipeline, water supply, sewer system, ventilation system, electricity.
6. Construction work must also be organized sequentially at the construction site.
7. Do not forget about installation and dismantling work, which also requires organization.
8. It is worth considering measures that are responsible for preserving the environment during the work process. There is a requirement here - the building complies with fire safety regulations.
9. Any building must be provided for all categories of citizens, including those with disabilities.
10. In the process of carrying out work, measures should be taken that are aimed at increasing energy efficiency.
11. At the legislative level, other documentation is provided that requires coordination and approval with regulatory authorities and the customer.

Pre-project documents

Stages and stages of design are also found in pre-design documents, which represent primary documentation reflecting complex solutions using sketches and models developed in special programs. At this stage, the following issues are considered and resolved:

1. The layout of the future building on the plot of land allocated for construction is identified.
2. Technical and economic calculations are being carried out, which are necessary in order to make the project more attractive to planned investors.
3. The building must fit into the architecture of the area, for which an appropriate project is also considered and drawn up.
4. We should not forget about the functionality of the future building, which should be convenient for all visitors.

Project stage

Design is considered the most critical and time-consuming stage. At this stage, the safety of all structures that are erected during construction work is ensured. The developed project complies with all established standards and requirements that are specified in regulatory documents. The design process does not provide for a thorough inspection of components. All documents included in the project consist of two sections, which include text and graphic documents.

The text section contains information regarding all technical decisions that were made during the design. Also included are explanations and relevant links to documents and calculations that will be needed to complete further work.

The graphic part includes all drawings, diagrams, plans and models developed through special programs. Decisions within the project must necessarily be subject to expert evaluation to identify shortcomings and further adjustments. After the project has been reviewed by experts and a positive decision has been made regarding it, the next stage of development can begin. The documentation that was approved at the design stage is subsequently used to create drawings and estimates.

Stage that includes working documents

Working design documentation at the design stage is developed in the most thorough manner. This is due to the fact that the following documents are being developed within its framework:

1. Drawings for the future structure, which must be numbered and signed, which makes it easier to work in the future, when individual drawings are combined into a single whole.
2. Drawing up estimate documents.
3. Description of the characteristics of the equipment that will be required during work on the construction site.
4. A statement containing a list of all the necessary materials for the construction of a future structure.
5. A statement that includes the volumes of construction and installation work.
6. Other documents that will be needed when carrying out the work are also attached to the general package of documents.

Working documentation is used on site by construction and installation teams. Drawings may need to be presented to specialists who supervise compliance with technical and copyright rights. The composition of the working documents is determined depending on the type of facility on which the work is planned, which is indicated accordingly when concluding an agreement with the designers. All working drawings must strictly comply with the standards established by a special system. All designed documents that will be used in the work, as well as construction work, must be carried out strictly in compliance with GOST.

A number of requirements for a construction site

Requirements in the process of work are imposed not only on the design stage, composition and content. The site intended for construction must also comply with them:

1. The area allocated for construction work must be of such dimensions and configuration as to facilitate the location of the structure in such a way that it meets all requirements during operation.
2. The allocated plot of land, as well as the surrounding area, must have a convenient topography. This is necessary in order to provide the most comfortable working conditions. There should be no underwater water underground.
3. The soil under the construction site must comply with established standards and requirements, the load must be within the permissible level. These requirements should be observed not only when installing the foundation of the future building, but also when installing working equipment.
4. The construction and design stages comply with the standards at the legislative level. It is strictly forbidden to start construction in those places where mineral exploration work has been found or is just being planned. This point includes places that may collapse.
5. When construction begins, there must be a water supply or other source of water nearby.

If the construction of a future facility is planned within the city, then the work should be carried out on the leeward side in relation to residential complexes.

The technical design of all stages of work must be agreed upon with the customer, who bears full responsibility for this, as well as for the selection of land for construction. The customer, together with the design organization, must:

1. Obtain from the organization that is interested in carrying out the work an agreement to connect the designed facility to the electrical network.
2. Develop all the necessary documents and materials, including calculations, and then choose the optimal solution.
3. It is necessary to calculate in advance the damage that can be caused when using a plot of land for construction.
4. Carry out the necessary engineering studies.

In order to select the required plot of land, the customer must create a commission. It should include a representative from the customer, members of the local administration, the general designer, and a representative of state supervision.

When the need arises to develop a project, the customer and the design organization need to understand what design stage is necessary for a particular object. For some objects it is possible to carry out design work in one stage, for others - in two stages, for particularly complex objects it is necessary to complete three stages of design. So, for example, it is performed in one stage, in two stages, or for a large supermarket it is performed in three stages. The price for the development of each stage is different and is determined on the basis of state collections of prices for design work for construction (SCPRS).

In this article we will consider the main stages of design, as well as the terms and definitions used in the development of design documentation.

According to DBN A.2.2-3:2012, there are the following design stages:
— feasibility study ( Feasibility study );
— technical and economic calculation ( TER );
- preliminary design ( EP );
- project ( P );
— working draft ( RP );
— working documentation ( R )

Let's look at each of them in more detail.

Feasibility study stage (TEP) . It is developed on the basis of the customer’s instructions for industrial facilities and linear engineering and transport infrastructure facilities, which require detailed justification of the relevant decisions and determination of options and feasibility of construction of the facility.
FER is used for technically simple industrial facilities and linear engineering and transport infrastructure facilities. Feasibility study is carried out in a reduced volume compared to feasibility study, depending on the nature of the object and the requirements of the task.

EP stage . It is developed on the basis of the customer’s instructions to fundamentally determine the requirements for urban planning, architectural, artistic, environmental and functional solutions for the facility, confirming the possibility of creating a non-production facility.
As part of the EP, to justify the decisions made on the customer's instructions, calculations of the main design solutions, estimated costs and justification of the effectiveness of investments are carried out, and engineering and technical developments and schemes for the engineering support of the facility can also be additionally carried out.

Stage P. It is developed to determine urban planning, architectural, artistic, environmental, technical, technological, engineering solutions for the object, and the estimated cost of construction.
P is developed on the basis of the design assignment, initial data and the previous stage approved during the three-stage design. Sections of stage P are given in a clear and concise form, without excessive detail, in a composition and volume sufficient to justify design decisions, determine the volume of basic construction work, the need for equipment, building materials and structures, provisions for organizing construction, as well as definitions estimated cost of construction.

RP stage. It is developed for technically simple objects, as well as objects using reuse projects (design solutions).
The RP is developed to determine urban planning, architectural, artistic, environmental, technical, technological, engineering solutions for the facility, the estimated cost of construction and construction work. RP is an integrating design stage and consists of two parts - approved and working documentation.

Stage R. Developed based on the approved previous stage. After approval of stage P, by decision of the customer, working documentation can be developed by the author of the project or another designer. The development of working documentation by other designers is carried out in compliance with the author's decisions of the approved P and in compliance with copyrights.

Design stages depending on the complexity categories of the object:
1. For objects I and II categories of complexity design is carried out:
a) In one stage - working draft (DP);
b) In two stages - for non-production objects - a preliminary design (ED), and for industrial objects and linear objects of engineering and transport infrastructure - a technical and economic calculation (TEC) and for both - a working design (DP).
2. For objects III category of complexity design is carried out in two stages:
— project (P);
— working documentation (P).
3. For objects IV and V categories of complexity design is carried out in three stages:
- for non-production objects - an EP or with appropriate justification of a feasibility study, and for production facilities and linear objects of engineering and transport infrastructure - a feasibility study (feasibility study);
— project (P);
— working documentation (P).

5 comments on this post

Single stage(working draft of the RP, including the approved part and working documentation) - for coordination and approval of technically simple objects using projects of mass and repeated use of I and II categories of complexity

Two-stage(project P, working documentation R) - for technically complex civil facilities, a preliminary design (ED) is additionally developed, for industrial facilities - a feasibility study of investments (TES). For individual objects, after approval of the EP or feasibility study, a RP can be developed, and after its approval, a R.

For objects of the III category of complexity, design is carried out in two stages:

Project (P)
- working documentation (P)

Three-stage(pre-design proposals EP or feasibility study, project P, working documentation R) - for objects of V, IV categories of complexity, technically complex in relation to urban planning, architectural, artistic and environmental conditions, engineering support, the introduction of new construction technologies, structures and materials, design is carried out in three stages.

For civil objects - EP, and for industrial objects - feasibility study;
- project (P);
- working documentation (P).

The head of the design organization appoints, by appropriate orders, chief architects and chief engineers of projects to develop all stages of design.

The responsible persons for the technical, economic, aesthetic and environmental qualities of the project are the chief project architect (CAP) or the chief project engineer (CPI). They prepare contracts, coordinate the actions of performers, and negotiate with customers, subcontractors and contractors. The responsible persons for the quality of a certain section of the project are the head and chief specialist of the corresponding project unit.

The preliminary design, investment feasibility study, project and working draft are signed by the management and main executors of the design organization. The title page of the explanatory note is signed by the head of the organization (director, chief engineer, chief architect), the head of the workshop (department), the chief architect (engineer) of the project, the authors of the project (if there are any, except GAP, GIP). Sections of the explanatory note are signed by the main specialists of the departments, the authors of the sections (if any), and the performers. The drawings are signed by the head of the workshop (department), the chief architect (engineer) of the project, the authors of the project (if there are any, except for the State Aviation Administration and the State Inspectorate), chief specialists, and performers. The explanatory note indicates the names of the design participants for each section of the project and, if there are subcontractors, the names of the companies or individuals of the subcontractors.

When developing design documentation, designers are responsible and ensure:

Compliance with architectural and urban planning requirements and high architectural and artistic quality;
- compliance with the requirements of current regulatory documents;
- protection of the natural environment, environmental safety and rational use of natural resources in accordance with DBN A.2.2-1;
- compliance with energy saving requirements;
- operational reliability;
- investment efficiency;
- patent purity of the adopted technical solutions and equipment used;
- compliance of design solutions with initial data and permitting documents.

Pre-project proposal.

A pre-project proposal is the primary set of documents required to pass the regulations in the relevant region and obtain the initial permitting documentation or architectural planning assignment. In addition, these are materials that allow you to evaluate the project and formulate precise requirements for further design.

Development is perhaps the best, if not the only way to evaluate and get an idea of ​​the project being designed in advance. This stage is especially important for large objects, as it allows you to avoid many difficulties during further design. At this stage, the design, layout, number of floors, materials, technical equipment, and architectural design are fundamentally determined; all this should give a clear idea of ​​the organization of the plan, the volumetric structure and appearance of the structure. The pre-project stage is decisive, determining the further path of project development.
At the next stage, based on the design assignment, a project and a working design are developed, which are developed for each type of work, and during construction they are the main technical documents.

Draft design and feasibility study of the investment.

A preliminary design (DS) contains fundamental solutions to urban planning, architectural, artistic, functional, environmental requirements for the design assignment, confirms the fundamental possibility of creating an object, and determines its cost.

To justify the adoption of architectural decisions, as part of the graphic part and explanatory note of the preliminary design, engineering, technical and structural developments, schemes for the engineering support of the facility and justification of the effectiveness of investments can be additionally carried out.

The EP is developed in compliance with existing urban planning documentation, architectural and planning assignments, and environmental protection requirements.

After approval or approval by the urban planning and architecture authorities, the ES is the basis for further development of project documentation.

Feasibility study of investments (feasibility study)

is developed for technically complex industrial facilities, including transport, energy, hydraulic engineering, reclamation and other special types of construction; a feasibility study for investments substantiates the need and feasibility of construction or reconstruction of industrial facilities, incl. their technical feasibility and investment efficiency. The investment feasibility study should consider decisions regarding the location, capacity of the facility, assessing the impact of the projected activity on the environment, compliance with architectural and other requirements in accordance with the design assignment. The investment feasibility study, after its approval or approval, is the basis for the further development of project documentation.

Project development.

A project (P) for the construction of a civil facility is developed on the basis of initial data, design assignments, and an agreed preliminary design (if available). It consists of the following main sections.

Architectural and construction solution, general plan, landscaping, transport scheme (if necessary),

Technological part (if necessary),

Environmental Impact Assessment (EIA) The need to develop an EIA is determined with the participation of government agencies for environmental protection,

Organization of construction,

Estimate documentation,

Bill of quantities.

A project for the construction, expansion and reconstruction of an industrial facility is developed on the basis of initial data, design assignments and an agreed feasibility study for investments (if necessary). It should consist of the following main sections:

Explanatory note with initial data,

Master plan and transport,

Technological part

Solutions for engineering equipment and external engineering networks,

Architectural and construction solutions,

Organization of construction,

Environmental impact assessment (EIA) in accordance with the requirements of DBN A.2.2-1-95,

Estimate documentation,

Collections of specifications for equipment, materials, structures and products,

Bills of quantities,

Technical and economic part, economic indicators

Working draft.

Detailed design (DP) is a combined design stage intended for the coordination and approval of design documentation, as well as for the construction of the facility. It is carried out on the basis of agreed planning documentation, state industry development programs or agreed pre-design studies, design assignments, architectural and planning assignments, initial data and technical conditions for connecting to sources of engineering support.

The working draft consists of an explanatory note (with technical and economic indicators), working drawings, estimate documentation and a construction organization section.

Working documentation.

Detailed documentation (P) is intended for construction.
It includes:

Working drawings, which are developed in accordance with the requirements of standards (DSTU and GOST),

Finishing work certificate

Estimate documentation,

Statement of quantities of construction and installation works,

Collections of specifications for equipment, products and materials according to DSTU B A.2.4-10-95 (GOST 21.110-95),

Questionnaires and dimensional drawings for relevant types of equipment and products,

Initial requirements for the development of design documentation for individually manufactured equipment (including non-standard and non-standardized equipment)

The scope and detail of working drawings must comply with the requirements of the "Design Documentation System for Construction" standards.

After approval of the project (draft design, feasibility study of investments), according to the customer’s decision, working drawings can be developed by a contractor or another designer (with a license), incl. with the involvement of the authors.

Detailed drawings of metal structures (DM) and process pipelines should be developed by manufacturing plants, and detail drawings of air ducts - by installation organizations. In some cases, the designer can undertake the development of detail drawings of metal structures (DM) and process pipelines for a fee.

Working drawings, as a rule, are signed by the head of the workshop (department), the chief architect (engineer) of the project, the chief specialist of the relevant section, the contractor and the person responsible for standard control.

The design documentation is developed after approval of the previous design stage.

The cost of design work is determined in accordance with the procedure and rules for determining the cost of design and survey work for new construction, reconstruction and technical re-equipment of enterprises, buildings and structures of all sectors of the national economy of Ukraine.

Coordination of project documentation.

The developed design documentation is subject to approval.
The preliminary design (ED) and feasibility study of investments are agreed upon

With local authorities of urban planning and architecture - on issues of placement, rational use of the territory intended for allocation, compliance of the solutions provided for by the project with the requirements of the architectural and planning assignment, current urban planning documentation,

With local governments - on issues of location, use of existing sources of supply, engineering communications, conditions for their development (to obtain official technical conditions for the preparation of initial data necessary for the development of P and RD), as well as the use of labor resources (when creating new jobs at production facilities)

Projects and working drafts are coordinated with local urban planning and architecture authorities (if the project was developed without the preliminary development of an electronic design and feasibility study for investments) and with local government authorities (which issued technical conditions for connection to supply sources or utilities).

If there are special conditions for the location of the object (historical zones of cities, landslide areas, etc.), it is necessary, according to the instructions of the urban planning and architecture authorities, to coordinate the design documentation with the relevant organizations.

Project documentation developed in accordance with state regulations and certified by the signatures of the chief architect (engineer) of the project is not subject to approval by state supervisory authorities, except in cases provided for by the legislation of Ukraine. In the absence of design rules and regulations, the adopted design decisions must be coordinated with the relevant state supervisory authorities.

Design documentation made with justified deviations from current state regulatory documents is subject to approval only in relation to these deviations with the relevant state supervisory authorities.

Project documentation for reconstruction is subject to coordination with urban planning and architecture authorities in cases of changes in the color scheme of the facade of buildings, architectural solutions (affecting the previously established character of the surrounding buildings), design solutions (which may cause dangerous situations in the future when operating conditions change).

Coordination is not carried out if the design documentation for reconstruction does not foresee changes in urban planning conditions, building facades, conditions of transport connections, engineering support, requirements relating to environmental protection, and the requirements of current regulatory documents for design are not violated. In this case, the examination is carried out in accordance with current regulations.

Examination and approval of design documentation.

Project documentation (EP, feasibility study of investments, P, RP) before its approval is subject to mandatory state examination in accordance with current legislation.

When examining investment projects, Ukrinvestexpertiza services involve environmental protection and nuclear safety authorities, labor safety control authorities, other state supervision bodies, specialized services of local governments, representatives of public associations and take into account their conclusions.

Customers who carry out construction at their own expense independently determine the procedure for undergoing examination of the relevant projects. At the same time, the level of compliance with safety requirements for life and health of the population, environmental protection and energy saving is subject to mandatory state examination.

Design documentation that is not subject to approval can be submitted for examination only by decision of the customer.

Submission of project documentation for approval, examination and approval is the responsibility of the customer and is carried out at his expense. The designer is obliged to defend his design decisions.

Project documentation (EP, feasibility study of investments, P, RP) comes into force after its approval by the customer. Approval is recorded in the form of an order (instruction or decision). The approval document provides the basic data and technical and economic indicators of the object. The names of the State Civil Aviation Administration or State Inspectorate, as well as the authors of the project, are included in the approval documents and protocols of coordination with the urban planning and architecture authorities.

The designer is responsible for the quality of design solutions, compliance with current regulations and legislative acts. Having approved the design documentation, the customer is responsible to the state for compliance with the requirements of regulatory documents and for the design solutions provided for in the documentation. For the transfer to production of design documentation that does not comply with the mandatory requirements of regulatory documents, the customer is responsible in accordance with current legislation.
