Development of a working project

After receiving the sketch project of the building the customer has already formed a final idea about the scale of his individual house, the number of floors, the number of rooms in it, the stylistic decision, etc. But the sketch project does not provide answers to other very important questions. For example, what to build from and what technologies to use, what engineering networks will be in the building and how they will pass through the building, how many resources are needed for construction, how to distribute them, how to organize the building construction process, how to get a permit for construction work, etc.

House project

Working project (WP)

After sketch approval, the working design begins - the formation of working documentation.

Finalization of the sketch project is being carried out, in particular: project markings of the main elements of the building are set, the necessary nodes are being developed, dimensional chains are attached. Detailing of the decorative elements of the facade is being carried out. Working documentation and architectural and construction drawings are being formed, on the basis of which the constructive solutions section will be developed.

The working project is developed in accordance with the DBN for architecturally and technically simple objects that belong to the class of consequences (responsibility) CC1. Most individual houses belong to this category. This stage is often called combined due to the fact that it combines the project stage Project (P) and Working documentation (WD), but at the same time it is simplified in some sections.

The project of the facade of the house

The working project is a complex stage of project work and includes:

  • coordination part of the project,
  • working drawings (working documentation).

The approval part of the working project - This is a project for obtaining a building permit. It is carried out to the extent necessary for the submission of the project to the State Gas Agency and the passing of an examination, if necessary.

The approval part consists of an explanatory note, made in a reduced volume relative to the project, depending on the type of construction and the functional purpose of the object, the estimate documentation, the construction organization section and drawings. The explanatory note should include a section of EIA (environmental impact assessment).

Organization of construction

The composition, scope and content of the design documentation of the section are established in accordance with the requirements and recommendations of the DBN A.3.1-5.

The organization of construction production consists in directing organizational, technical, technological decisions and other measures to the implementation of project decisions regarding the construction of the object in compliance with the requirements of legislation and regulatory documents and provision during construction.

Estimated documentation

At the WP stage, the cost documentation is drawn up:

  • summarization of costs (in the case when the implementation of construction and commissioning of the construction object is envisaged in separate lines);
  • consolidated estimates of the cost of construction objects;
  • object estimates;
  • local estimates;
  • resource information for local estimates;
  • resource information for object estimates;
  • information on resources for consolidated estimates of the cost of construction objects;
  • estimated calculations;
  • information on the estimated cost of the construction of houses, buildings, structures, linear objects of the engineering and transport infrastructure, which are included in the launch complexes;
  • estimates for design and research works.

Thanks to the development of a working project of a country house, the total cost of all materials and works is calculated quite accurately, which will allow you to complete the construction on time and enjoy life in a new house.
