Terms of Reference - initial documentation that is drawn up in pursuance of the contractual obligations of certain parties.

In this document, the customer describes in detail what the contractor must do. Indicates specifications of the object being created, sets out other requirements.

What is such a document for?

In accordance with civil law Russian Federation, provides for the possibility of drawing up and handing over to the performer of such an assignment.

In particular, this is provided for by Article 774 of the Civil Code of the Russian Federation, on the basis of which, when performing scientific and technical work, the contract may provide for the obligation of the customer to prepare the above document, as well as to agree on the program and the scope of work with the contractor.

The terms of reference, as a rule, are always stipulated by the conditions government contracts for the manufacture of products, performance of work, provision of services. The parameters of the technical assignment are first indicated in the tender documentation. The person who won the competition is obliged to strictly comply with all technical parameters.

If necessary, when performing work, rendering services, by agreement of the parties, additional technical specifications may be drawn up. This is formalized in the form of additional agreements to the contract, which come into force only after approval by all parties to the contract.

Features of drawing up a task

In this case, the following parameters are indicated

The name and quantity of the supplied goods.

Delivery address.

Delivery time.

Types of supplied goods, their completeness.

Requirements for the quality of goods.

Other required specifications.

In any case, the terms of reference drawn up and prepared under any contract is an integral part of it. This document is signed by all parties to the transaction and certified by the seals of the organizations. The task can also have attachments in the form of pictures, drawings, other documentation or samples of supplied products.

If deliveries of products are carried out repeatedly, then both a single document (task) and documents for each specific delivery can be drawn up. The terms of reference can be signed by both the sole executive bodies of organizations ( CEOs, directors) and their representatives. The powers of representatives are formalized in the form of powers of attorney.

Our website contains different kinds technical assignments. You can download them absolutely free. If necessary, we can provide a preparation service required document by personal order. Please contact us and we will definitely help you.

Terms of reference for design

1. Basis for work: Contract No. _________ dated __.__. 201_. with "_______________________________________".

2. Contractor: JSC "___________________"

3. Purpose of work: To develop technical requirements to the sound reinforcement and sound reproduction system (electroacoustics) of the object: _________________________________.

The importance of the correct execution (drawing up) of the design assignment (RFP) is beyond doubt, since the better the RFP is, the fewer problems for all parties of the process. In this case, the more detailed and transparent the RFP, the more precise the wording, the more correct the adopted technical solutions and the cost of project documentation (PD) and construction and installation work will be. The design process, like any process, can be described something like this:

What the customer wants

The customer wants everything that is possible to be spelled out in the RFP, while the cunning customer prescribes ambiguous formulations in the RFP like:

• Do everything necessary (develop documentation) to obtain a positive State Expertise (SE).

You yourself understand that experts are different and the requirements can go very far beyond the scope of project documentation. And also, if the Customer prescribes in the RFP the collection of all the necessary initial data, including technical specifications, technical specifications, then even if the Customer is to blame for their failure to receive or failure to fulfill them, then the failure to obtain a positive conclusion of the PoE for this reason may well be imputed to the Contractor (such as not "provided , not assembled, or collected the wrong thing "with which you can" go through the GE ").

• Issue design documentation in accordance with the Decree of the Government of the Russian Federation No. 87.

This is also an interesting question. Let's say the stage is "overhaul". Is it necessary to develop PD in full (by sections) for all facilities in accordance with Resolution 87? There are well-founded doubts and it is better that this be spelled out in the RFP. And if the stage is "reconstruction", and you, for example, change some electric actuator on the valve, then why develop all the sections?

I had such a precedent. We are changing the valve, R&D (design and survey work) is almost a penny, but the RFP stipulates to do it according to Resolution 87, although the operator (builder) does not need this at all (no one needs it), but the general designer (large design organization; departmental institute of a large company; an inadequate examination department, stamping out the army traditions of the Company itself in the worst form) clung to it, and you will not get rid of it. What, are we going to sue a large Fuel and Energy Company? It’s more expensive, you’ll lose the market and your reputation at the same time, although you can be right 100 times ... These are the nuances ...

• Execute design documentation in accordance with the current regulatory documents of the Russian Federation.

We all know that there are recommended, there is a list of mandatory documents of the Russian Federation, on which, again, the state examination has its own "special" opinion. Sometimes an expert can interpret ND in such an exotic way that one simply marvels, or demand something that is not spelled out in any ND of the Russian Federation. Well, this is a separate song - about Expertise, which requires a separate discussion.

In addition, already in the RFP (if this is not in the contract), the Customer can prescribe a system for monitoring the development of PD on his part (such as a schedule with labor costs and people, a weekly report in an approved form, conference calls, etc.).

What the Contractor wants

The contractor wants everything in the RFP to be as specific as possible (especially with regard to the completeness of the initial data and volumes design work, technical requirements) in order to minimize the number of "wishes" of the Customer to the maximum that arise at almost any stage of the design. Therefore, if the Contractor himself writes the RFP, then he prescribes absolutely everything he knows about the object, and also what to design at this object, indicating specific parameters and requirements.

How do salaries appear?

It depends on the Customer. Usually, large Customers have their own developed form of RFP and the Contractor cannot do anything with this, since this TK is played in the tender and cannot be changed. Even if there are errors, inaccuracies or contradictions in the RFP, it is extremely difficult to correct the RFP for a large Customer (bureaucracy-sss). There the signatures of high bosses are ( common mistake The customer, the RFP should not contain the signatures of high bosses, there should still be a division of the levels of responsibility), who need to somehow explain why the RFP actually changed, which one made a mistake, submit it here, let's punish him ... well, who will go to such a boss to explain it? Problematic, isn't it? There is experience, for the second year we are agreeing on the change in the RFP (the ravine has grown, a natural disaster), but “the cart is still there”. We even flew by helicopter, albeit with “middle bosses”, but who will go to the “high” ones? Bummer ...

Average Customers can act in different ways. The most adequate ones allow you to reasonably adjust your salary.

Small Customers either make up the RFP themselves, or entrust it to the Contractor. As a rule, it is more comfortable to work with medium and small customers. Large Customers also have their advantages, for example, more numerous and well-paid highly qualified personnel and well-established “work organization traditions” that can help the process in some way (for example, the timeliness of responses to the Contractor's inquiries and letters).

The composition of the salary

The composition of the RFP, as a rule, is taken by a large Customer (Gazprom, Rosneft, etc.) regulatory document or, if there is no such document, it forms according to accepted traditions, taking the existing RFP as an analogue.

We present to you for understanding the structure of the salary of some large Companies of the salary forms and.

In principle, quite decent salaries, there are certainly unnecessary items (they still understand that in large companies there are many departments and everyone wants to put their own point in the document), but the form can be used as an analogue, although in the second part of the article I will include in the text a link to a more adequate draft RFP.

The main sections of the RFP are as follows:

• Basis for the development of project documentation
• Customer and contractor, address of the design object, stage and stages of design
• Location of the design object
• Type of documentation (or design stage)

For the above points, of course, you need a clear understanding in the RFP: who is the customer, who is the contractor, where the design object is located and what is the design stage (new construction, reconstruction, overhaul).

• Initial data

In the initial data provided by the Customer, it is advisable to prescribe everything that the Customer has, including the survey materials, engineering surveys... Of course, the Contractor requests a lot of information from the Customer during the design process for the development of individual sections of the PD, especially such as "Fire safety measures", "Environmental protection measures", etc.

In accordance with Decree No. 87 of the Government of the Russian Federation, there are only two design stages in the Russian Federation: design and working documentation... The stage of "working design" (WP), previously a ubiquitous term, has practically gone out of circulation, although it is found in some secondary documents related to design.

At the same time, the term RP had a completely normal logical explanation - this is design and working documentation in one bottle (being developed simultaneously). For example, for overhaul there is no need to separate the design at the stage, but immediately develop everything that is required, especially since the PD of the overhaul does not go to the State Expertise. And here some Customers go for a trick. For example, OAO Gazprom has developed an internal document “Linear part of gas trunklines. General technical requirements for project documentation for overhaul ", in which he introduced a new term for project documentation -" PD KR "( project documentation overhaul), which is being developed in one stage (LLC "Transenergostroy" participated in the development of this document).

Often the customer incorrectly determines the design stage, sometimes unconsciously, sometimes quite deliberately, trying to tighten the financing of the object to its existing cost item. Because of this "misunderstanding", problems may then arise when passing the State Expertise (which will force the RFP to be redone) or, for example, with Rostekhnadzor.

• Documentation development procedure

The paragraph prescribes the stages of PD development (development sequence), for example:

1. Collection of initial data;
2. Engineering survey;
3. Basic technical solutions (as part of the PD);
4. Customer expertise;
5. External expertise.

• The main characteristics of the object

Technical characteristics of the object before and after construction (reconstruction, overhaul, new construction).

• Requirements for the identification of a building or structure

These requirements are spelled out in 384-FZ "Technical Regulations for the Safety of Buildings and Structures" Article 4, which explicitly states the need to indicate these signs of developers in the design assignment and engineering survey assignment:

1. Appointment;
2. Belonging to objects transport infrastructure and to other objects, the functional and technological features of which affect their safety;
3. Possibility of hazardous natural processes and phenomena and man-made impacts on the territory where the construction, reconstruction and operation of a building or structure will be carried out;
4. Belonging to hazardous production facilities;
5. Fire and explosion hazard;
6. The presence of premises with the constant presence of people;
7. Responsibility level.

• Requirements for the design organization

It is clear that the Contractor must have the appropriate permits and SRO certificate, which indicates that he can be designed.

• Normative documents for design

(the list can be attached to the assignment separately).

Features of technical regulation in the field of ensuring the safety of buildings and structures and related design processes (including surveys), construction, operation and disposal (demolition) are established by the Urban Planning Code of the Russian Federation, the Technical Regulations on the Safety of Buildings and Structures ( the federal law dated 30.12.2009 No. 384-FZ), adopted in accordance with technical regulations on the safety of buildings and structures by national standards (GOST) and codes of practice (SP), as well as other regulatory documents.

The procedure for the development, adoption, application and implementation of mandatory requirements for buildings and structures during their design and construction is determined by the Federal Law of December 27, 2002 No. 184-FZ "On technical regulation" (hereinafter - Law No. 184-FZ).

In accordance with Law No. 184-FZ, in order to establish mandatory requirements for the safety of buildings and related design processes (including surveys), construction, operation, and disposal (demolition), the Technical Regulations on the Safety of Buildings and Structures (Federal Law dated 30.12. 2009 No. 384-FZ) (hereinafter - the Technical Regulations).

The objects of regulation by technical regulations are:

1. Buildings and structures for any purpose (including their constituent networks and systems of engineering and technical support),
2. As well as the processes of design (including survey), construction, installation, adjustment, operation and disposal (demolition) related to buildings and structures.

Compliance with the requirements of the specified technical regulation is ensured by national standards and sets of rules adopted in accordance with this technical regulation.

• Special conditions and design requirements

For example, construction without stopping an enterprise, a requirement for the development of a STU is possible (if the existing norms of the Russian Federation are violated or the insufficiency of such norms is obvious). There may be special requirements for the use of equipment and materials, stages in the implementation of design or pre-design work.

• Requirements for conducting engineering surveys

If engineering surveys are required, then usually a separate task for performing engineering surveys (AI) is drawn up, which is separately agreed upon by the Customer. It is possible to prescribe this requirement for the design of the RFP for AI in the general TK (together with the requirement for the development and approval of the Survey Program). You can specify the boundaries of the survey, area, scale, types of surveys, as well as the specifics of conducting certain types of surveys.

• Variant development requirements

The variability can be technical, organizational, and other solutions described in the project documentation.

• Requirements for constructive and engineering solutions

For each section or subsection (including engineering systems) their requirements must be spelled out.

• Requirements for the development of environmental protection measures

It is possible to prescribe "in accordance with the environmental legislation of the Russian Federation", or it can be expanded, not to forget about public hearings (if necessary), about EIA (assessment of impacts on environment), various monitoring. It is possible to include the development and approval of a sanitary protection zone (sanitary protection zone), without which it can be problematic to obtain a positive conclusion of the State Expertise. You can indicate about the reclamation project and its approval in local authorities(there was such a comment from the GoE). In general, your "ecological" fantasy can be obscenely large.

• Fire safety requirements

Well, it is clear that the documentation must be developed in accordance with the norms of the Russian Federation. Additionally (if this is a site facility), you can add a requirement for fire alarm and fire extinguishing systems, specify what and how to extinguish, requirements for automatic fire extinguishing, a requirement for calculating risks. You can also add a fire extinguishing plan (although this does not apply to PD).

• Requirements for the organization and working conditions of employees

This requirement separately, as a rule, is prescribed for a new object, for which it is necessary to determine the personnel serving the object. Additionally, this requirement can be spelled out in the technological part of the project.

• System requirements information security(IS) and engineering and technical means of protection (ITSO complex) of objects

Such requirements are specific and different for each Customer. Some Customers provide technical requirements separately after the contractor has agreed on the composition of the personnel and the layout of the premises where the personnel work and rest.

• Industrial safety requirements (PB)

This requirement is rarely spelled out as a separate item in the RFP, since these requirements should be taken into account in most sections of the project, but it is possible to prescribe the RF ND on this topic, profile FZs and industrial safety standards.

• Compilation requirement estimate documentation(SD)

The estimate documentation also has its own specifics for each Customer (at what prices to count; in which program, at what prices; what to consider, what is not; the requirement to provide price lists for equipment (for example, in 2-3 copies)).

• The composition of the transmitted demonstration materials

It is possible to prescribe a requirement to provide presentation materials (for example, basic technical solutions for the Customer, presentations for public hearings, etc.), designed accordingly. Buildings may be required to provide 3D images, models, etc.

• Requirement for conducting external examinations

1. Internal expertise of the customer (which structures are involved and which sections are checked);
2. External expertise (to which organizations and what documentation to submit for expertise):

State expertise.

Non-state expertise.

• Requirements for registration and transfer of materials to the Customer:

1. The number of documents to be transferred (on paper and electronic media);
2. How to draw up paperwork;
3. Format of registration on electronic media.

As we all already understood, the topic of the correct design of the RFP from the point of view of the Customer and the Contractor occupies an important place in the design process and is especially important for the development of a high-quality project and the elimination of possible misunderstandings between the Customer and the Contractor.

In general, until we meet again, do it efficiently and sleep well :-))))!

You decided to build your own Vacation home to be able to enjoy peace, quiet and clean air in your free time? We can only congratulate you! Yes, a lot of trouble awaits you - buying a plot, building a house, making a decision legal issues but the result is definitely worth it.

But before starting construction, you should transfer the technical assignment for the design of the building to specialists in order to get a full-fledged project of the future house.

Example building design

Before you start compiling a full-fledged project at home, you need to do some preliminary work. And draw up a document on the basis of which architects will work on its implementation. This document will be the terms of reference for the design of the house.

It presents regulatory and technical requirements, the purpose of the future structure, the time limits for the performance of work and many other things important for the construction. The preparation of this document involves carrying out various measurements and studies.

Here, many people have a question - is a project needed at all? After all, a small house of one or two floors is being built, not a skyscraper! So is the project a necessity or would it be a waste of money in this case? This is a very serious question that must be dealt with before making important decisions.

This document is a fundamental element of the project, and therefore the construction itself. This document regulates the relationship between the client and the contractor.

According to the terms of reference, the work is carried out in the prescribed manner, the principles and tasks of the contractor's activities are determined. Thus, it turns out that according to this document, the client can visit the facility under construction and check the compliance of the work performed with the project documentation.

At the same time, for the contractor, the technical task for designing a house is all the necessary data that give a complete picture of the parameters of the planned building and the ability to actually draw up a specific plan for the implementation of this.

First you need to decide on the cons - there are much fewer of them. Or rather, only two:

1. You will have to spend a decent amount of money designing your home. In some cases, the cost of the project reaches 3-5% of the value of the house, which scares off potential home owners;
2. When the task for the execution of the work on the preparation of the project is handed over to specialists, you will not always be able to quickly see the result of the work. Some companies, not valuing the time of their client, can provide a finished project only after a few months.

Finished building project

This is where the disadvantages of construction with the project end. Then there are exclusively advantages, which, in the opinion of most people, outweigh the disadvantages:

As you can see, there are much more pluses than minuses. Now you can decide for yourself whether you should spend money on the construction design or should you try to do all the work without a project.

Is the presence of the project a necessity from a legal point of view

Often people who decide to build own house, they just do not know if they will receive a building permit if they do not have a project for a future building. Because of this, they cannot make the right decision. In some cases, they waste money, and in others, they get down to work in order to find out very soon that the construction is being carried out illegally.

V Urban Planning Code there is article number 51, which says - you can get a building permit without finished project... So, only the developer himself decides whether to spend money on the project or not.

However, there are certain limitations here.

The area of ​​the house should not be more than 1500 m2, and the house itself should not have more than 3 floors.

Although, such houses are built by an extremely small number of people, and those who can afford it will probably not be forced to save money, and will be able to afford the services of even the most expensive designer.

How the project is created

The project can be created different ways... Some future home owners prefer to do all the work on their own. How justified is this and is it permissible at all? This will be discussed below.

An alternative to drawing up a project yourself is to conclude a cooperation agreement with a specialized company. In this case, you will only have to draw up a technical task - the specialists will do all the rest of the work on their own. However, many inexperienced people can be frightened by such a statement.

Sample cooperation agreement

When developing this document, the features of specific construction works... It is the specifics of future construction that determine the specifics of the design of the assignment. In this case, the client must mandatory transfer to the contractor all initial documents, including permits on the approval of the site of future construction, investment justification, and the act of site selection.

The terms of reference for the design of a house should be drawn up taking into account information on the implementation of a set of activities in research, architectural planning and development. Also, the document must necessarily reflect the possibility of connecting the future building to engineering systems and communications.

In fact, the terms of reference are often drawn up during an ordinary conversation with specialists. You will be asked leading questions, and from the answers received, a technical task is formed, on the basis of which the project of your house will be developed.

Typically, questions can be as follows:

• The structure, what shape and size are you planning to order?
• Will it be connected to engineering networks, and if so, to which ones?
• What materials will be used in the construction?
• What should be the design of the main elements?
• What construction time frame will suit you?
• How much are you willing to spend on building a house?

As you can see, these are fairly simple questions that can be answered by every person who at least vaguely imagines his future home. Based on your answers, experts will be able to draw up a detailed project.

Moreover, more often than not, several projects are drawn up so that you can choose exactly the one that suits your taste. By the way, the best solution will entrust the design of the house and its construction to one company.

This will achieve several benefits:

1. You can get a certain discount, since you order a whole range of services from one company (with such significant costs, even a saving of 1-2% will be a considerable amount).
2. If you discover any defects during the operation of the building, you know exactly who was the culprit, and you can go to court. If the project was developed by one company, and another was engaged in the construction of the house, it is highly likely that representatives of the companies will blame each other, which will make it almost impossible to find the last one.

We create a project ourselves

So, you've decided to develop a project that will build your dream home. As mentioned above, legally this is completely legal - you can simply sketch out an approximate project, on which the shape and dimensions of the premises will be indicated, and start construction on the basis of this project. As a result, you can save tens of thousands of rubles. But is this always the best way?

Self-design mistakes at home

The advantages of such a solution include savings and short terms, but this is where the advantages end. But the risk of making mistakes is quite high if you have never developed building projects. Also, poor market knowledge building materials often does not allow amateurs to choose the most effective technologies and solutions. It is possible that as a result, the built house will be very different from the one that you imagined in your dreams.

In general, self-design permissible only in cases when you are building a small country house. In many cases, its low weight makes it possible not to use a massive foundation. In addition, if it will be used only in the warm season, there is no need to connect it to a variety of communications - the only exception is electricity.

Professional waterproofing foundation

If the house needs a high-quality foundation, reliable vapor barrier and thermal insulation, and for a comfortable year-round living, it is necessary to connect heating, cold and hot water supply, bring the sewage system and carry out gasification, it would be better to entrust the work to professionals. An amateur simply will not be able to take into account all the nuances, as a result of which a lot of effort, time and money will be spent, and the built house will leave much to be desired.
