Technical task- this is the initial document intended for the design development of a construction object, containing all the data about the object and all the characteristics that the object should have after completion of work. Judging by the text composition, we can say that the terms of reference for construction are an example of what the customer wants.
The ideal drafted terms of reference for the construction design should include all the information that the customer can provide.
The customer must clearly understand what he wants to get at the output, and convey this information to the contractor.
The terms of reference usually consists of the following sections.
This section should contain the following information (at the discretion of the customer):
This paragraph should indicate those requirements of the customer that are not reflected in the previous paragraphs. For example, the availability of demonstration materials, the need to develop various passports for a future facility, the number of copies of project documentation.
As practice shows, such a complete construction task is developed only in cases of large newly organized construction of objects, including shopping centers and residential complexes. The information on each item should be as complete as the customer sees fit.
There are no uniform requirements for the design of technical specifications.
That is, the form of the task is almost arbitrary, but as understandable as possible for the performer. You can complete the task in the form of continuous formatted text, or you can also in tabular form.
When drawing up such a document as a technical assignment for the construction of a building, the customer needs to formulate all the important points as clearly as possible. The content of the task should not cause controversial issues or double perception. This document has legal weight and is mandatory attached to the contract between the contractor and the customer in the form of one of the main applications. For the correctness of the assignment, administrative responsibility lies with the direct executor.
Have you decided to build your own country house in order to be able to enjoy peace, quiet and clean air in your free time? You can only be congratulated! Yes, a lot of trouble awaits you - buying a plot, building a house, resolving legal issues, but the result is definitely worth it. But before starting construction, you should transfer the terms of reference for the design of the building to specialists in order to get a full-fledged project of the future home.
Building project example
Before you start drawing up a full-fledged project at home, you need to do some preliminary work. And draw up a document on the basis of which the architects will work on its implementation. This document will be the terms of reference for the design of the house.
It presents the regulatory and technical requirements, the purpose of the future structure, the time limits for the execution of work, and many other things important for the construction. The preparation of this document involves various measurements and studies.
Here, many people have a question - do you need a project at all? After all, a small house of one or two floors is being built, and 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 issue that should be dealt with before making important decisions.
This document is a fundamental element of the project, and consequently 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 terms of reference for designing a house are 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 minuses - there are much fewer of them. Or rather, just two:
Finished building project
On this, the shortcomings of the construction with the project end. Then there are only the advantages, which, according to most people, outweigh the disadvantages:
As you can see, there are much more pluses than minuses. Now you can decide for yourself whether to spend money on building design or whether to try to do all the work without a project.
Often people who decide to build their own house simply do not know if they will receive a building permit if they do not have a project for the future building. Because of this, they cannot make the right decision. In some cases, they waste money, and in others, they get to work, only to find out very soon that the construction is being carried out illegally.
The Urban Planning Code contains article No. 51, which says that it is possible to obtain a building permit without a 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 be no 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 certainly not be forced to save money, and will be able to afford the services of even the most expensive designer.
A project can be created in different ways. Some future home owners prefer to do all the work themselves. To what extent is this justified and is it permissible at all? This will be discussed below.
An alternative to independent drafting is the conclusion of a cooperation agreement with a specialized company. In this case, you will get only the preparation of the terms of reference - the rest of the work will be done by the specialists themselves. However, for many inexperienced people, such a statement can frankly frighten.
Sample cooperation agreement
When developing this document, the features of specific construction works are taken into account. It is the specifics of the future construction that determine the design features of the task. At the same time, the client must, without fail, transfer to the contractor all the initial documents, including permits on the approval of the place of future construction, justification of investments, and an act of site selection.
The terms of reference for designing a house should be drawn up taking into account information on the implementation of a set of activities in research, architectural planning and experimental design areas. 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 a normal conversation with specialists. You will be asked leading questions, and from the answers received, the terms of reference are formed, on the basis of which the project of your house will be developed.
Typically, the questions might be:
As you can see, these are fairly simple questions that every person who can at least vaguely imagine his future home can answer. Based on your answers, specialists will be able to draw up a detailed project.
Moreover, most often several projects are compiled so that you can choose exactly the one that would suit your taste. By the way, the best solution would be to entrust the design of the house and its construction to one company.
This will achieve several benefits:
So, you have decided to develop a project according to which the house of your dreams will be built. As mentioned above, this is legally quite legal - you can simply sketch out an approximate project, which will indicate the shape and size of the premises, and start construction based on this project. As a result, you can save tens of thousands of dollars. But is this method always optimal?
Home design mistakes
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 large if you have never developed building projects. In addition, poor knowledge of the building materials market often prevents amateurs from choosing the most effective technologies and solutions. It is possible that as a result the built house will be very different from the one you imagined in your dreams.
In general, self-design is permissible only in cases where you are building a small country house. In many cases, its low weight eliminates the need for a massive foundation. In addition, if it will be used only in the warm season, there is no need to connect it to various communications - the only exception is electricity.
Professional foundation waterproofing
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, connect sewage 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.
It was said above that, turning to specialists, you will be forced to spend a significant amount on paying their labor. However, it will pay off in full in the future.
Considering all the difficulties of preparing for the creation of a project, it is common practice to transfer such concerns for the creation and collection of all accompanying documentation to specialists.
Many people, realizing this, often turn to design companies, even if they want to build a country house.
True, in such situations they usually apply for such a service as preliminary design. This is the cheapest service, as it only provides for the creation of a project for the exterior design of the house. The rest of the work will have to be done independently. But the house will look just great - because real professionals have worked on its design.
So, you contact a construction company, answer questions from specialists, and based on your answers, a technical assignment is drawn up. It is a support for the implementation of the entire complex of construction works, so the terms of reference should be as complete as possible.
It is mandatory to include:
When the terms of reference are drawn up and formalized, further work is carried out by experienced designers. But there can be two options: buying a finished project or creating an individual one.
The first option will cost you much cheaper - most often a finished project can be purchased by spending from 20 to 50 thousand rubles.
In addition, you do not have to wait for specialists to develop a new project. You will simply be shown several dozen projects, each of which will meet your requirements in most respects. You will only need to choose the option that seems most suitable to you.
An example of a two-family house project
Alas, this solution does not suit everyone. It is possible that the project you like is designed for two parents and two children of the same sex. And you need a house where parents, two children of different sexes and one elderly person will live.
As a result, you will have to put up with a number of difficulties - to make changes to standard project no one will agree, since this will have to make a number of calculations and measurements. Think seriously! After all, you are building a house in which you will live for many years, not a few weeks!
And you certainly should not try to make adjustments yourself - this is fraught with the destruction of the house if you are not familiar with all the intricacies of the strength of materials and theoretical mechanics.
Ordering an individual project will cost much more. Its cost is several times higher than the cost of the finished project. But, choosing this option, you can demand that the project meet your requirements to the smallest detail. The size and location of rooms, the number of windows, the type of stairs, the location of sockets, the location of the bathroom - all this will be taken into account in accordance with your wishes.
The video details how to order a technical task for designing a house.
Yes, you will have to shell out a large amount, and wait several weeks or even months before the project is created from scratch. But as a result, you will get a house that will definitely not disappoint you either now or in many years.
Now, knowing about the different options for designing a house, you will surely be able to make the right decision, which you will not have to regret.
The terms of reference are understood as specialized documentation containing the main requirements of the customer for the objects of procurement, which defines a list of conditions under which the procurement will be carried out, what work is to be performed. Despite the fact that the legislation does not provide for the mandatory preparation of terms of reference for the performance of works and other services, this form of documentation is widespread, since thanks to the terms of reference, labor and time resources are saved at the following stages:
By filling out the terms of reference (hereinafter referred to as TOR) before placing a notice of the planned purchase, an optimal calculation of the time required for the performance of work or provision of goods, the selection of qualified specialists is achieved. Also, a properly drawn up TOR allows you to specify the object of procurement as much as possible, describing it as clearly and in detail as possible. Based on the pre-prepared TOR, a final assessment of the compliance of the procurement result with the initially declared characteristics is carried out.
Based on the information contained in this document, it becomes possible:
As a rule, the terms of reference are drawn up by the contract manager in tandem with the specialists of the legal department, after which the document is certified by a person authorized to make decisions related to the procurement. It is advisable to sign the document no more than 10 days before the date of formation of the notice and other related procurement documents. The terms of reference include:
Note! When drawing up TK, one should be guided by objectivity, using understandable and concise formulations that do not contain contradictions. The requirements of the ToR should be formed in accordance with the established practice, without contradicting the norms of the law.
When drawing up the TOR, it should be taken into account that, according to the terms of reference, the risks and burdens of suppliers and contractors should not exceed those assumed by the customer, otherwise this may lead to an increase in the cost of the contract, or to refusal to submit applications for participation.
The terms of reference for the performance of construction and installation works must contain the necessary criteria, according to which the required work must be carried out. When compiling the document, you should specify:
When drawing up the TOR for electrical work, the same principles apply as in the previous example. The items provide the following information:
Important! Due to the specifics of certain types of work, which include, in particular, electrical work, along with the standard requirements for auction participants, the customer may put forward special conditions in the terms of reference.
So, these may be requirements for the provision of information on admission to certain types of work, the availability of technical resources for their implementation, the provision of confirmation of the qualification level of the workers of the participant applying for participation in the auction.
According to the requirements of Federal Law No. 44-FZ, the customer must be guided by uniform requirements regarding the description of the object of procurement when preparing documents, regardless of the methods of actual execution of the contract. When issuing a TOR, the customer must be guided by the following directives:
Customers are obliged to rely on the provisions of the Federal Law No. 44-FZ "On the contract system in the field of procurement of goods, works, services", according to the requirements of which, the choice of a contractor or supplier is carried out according to the strict rules of an electronic auction, the winner of which, as a rule, becomes a participant, offering the lowest price. Therefore, it is extremely important to prepare the correct terms of reference, taking into account all the nuances of the ongoing procurement.
