DESIGN / TECHNICAL CONTROL

The conceptual design is a presentation of the planned concept of the facility, with a presentation and listing of all data necessary for determining and obtaining location conditions, issued by the competent authority or as part of an urban project for the needs of urban-architectural development of the location.

The conceptual design is made on the basis of data obtained from location information, the acquisition of which is not mandatory, or on the basis of insight into the planning document and separate, where it exists.

The conceptual design is made on a geodetic basis, for which it is not necessary to obtain certification, and which contains a topographic view of the terrain, with the boundaries of the plots drawn.

Preparation of the General design for the needs of preparation of planning documentation (Detailed regulation plan for the facility or urban plan), of course if necessary for a specific facility.

The general design aims to consider the resource and spatial possibilities and limitations of building construction, with the task to adopt through evaluation procedures the general concept, macrolocation and spatial disposition of the building, determine the basic functional, technological and technical characteristics of the building, construction stages, operating conditions, attitude towards space and environment, as well as the basis for economic analysis. In the event that several variant solutions are analyzed during the preparation of the general project, the selection of the optimal variant is made on the basis of natural, technical, technological, economic, functional, ecological and other conditions.

In the event that several variant solutions are analyzed during the preparation of the general project, the selection of the optimal variant is made on the basis of natural, technical, technological, economic, functional, ecological and other conditions.

The preliminary feasibility study shall determine in particular:

• Spatial, ecological, social, financial, market and economic justification of the investment, for variant solutions defined by the general project, on the basis of which the planning document is adopted;
• Decision on the justification of investment in previous works for the conceptual design and preparation of a feasibility study.

The preliminary feasibility study, of which the general project is an integral part, is obligatorily prepared only for facilities financed from the budget.

A preliminary feasibility study with a general design (or a feasibility study with a preliminary design) is also prepared for the purpose of obtaining an energy permit, for facilities for which this is prescribed by the Energy Law.

Preliminary design is made on the basis of the general design and location conditions, and it elaborates the concept of the facility determined by the general design, ie location conditions.

In the case of wind farms, it is subject to expert control by the Republic Audit Commission, which is a procedure of expert control by the commission formed by the Minister in charge of construction. The costs of the audit shall be borne by the investor.

Preliminary design is a set of mutually agreed projects which determine:

• purpose,
• position, shape and appearance of the object
• capacity and technical-technological and functional characteristics
• optimal routes under specific conditions and restrictions, with all accompanying facilities, for line infrastructure facilities;
  roughly proves the fulfillment of the basic requirements for the facility.

The feasibility study determines in particular the spatial, ecological, social, financial, market and economic justification of the investment for the selected solution, elaborated by the conceptual design, which is an integral part of it.

Based on the feasibility study, a decision is made on the justification of the investment, for projects financed from the budget.

The design for a construction permit is prepared on the basis of issued location conditions, regulations in the relevant field, measures for fulfilling the basic requirements for the facility determined by studies and studies (if prepared) and rules of the profession.

A design for a construction permit is a set of mutually agreed projects that define:

• Location and capacity of the facility on site
• Functionality from the point of view of technological and other requirements
• Spatial design
• Choice of constructive system
• Dimensioning of the main construction elements
• Principled selection of construction materials, installations and equipment, which ensures that the location conditions and basic requirements for the facility are met.

The preparation of the project for obtaining a construction permit is subject to mandatory verification and approval of the performed technical control of the project-technical documentation.

Additionally, for line infrastructure facilities, the project for a building permit unambiguously defines the route of the facility with all the necessary elements, which can only have micromovements in relation to the route from the conceptual design (if made), in order to optimize works.

Elaborations and studies are attached to the technical documentation, but do not form an integral part of it: Geotechnical Research Study, Energy Efficiency Study and Fire Protection Study.

A design for construction is a set of mutually agreed projects necessary for the execution of construction, craft and installation works and other works. PZI is not mandatory documentation for all categories of facilities.

The project determines:

• Construction-technical, technological and operational characteristics of the facility with equipment and installations,
• Technical-technological and organizational solutions for the construction of the facility,
• Investment value of the facility and
• Facility maintenance conditions.

The design for construction elaborates the details and technological solutions determined by the project for the construction permit, as well as the conceptual project for the reconstruction of the facility, which is performed on the basis of the decision approving the execution of these works.

The design for construction is made for the needs of building the facility and performing works. The preparation of the project for the execution is obligatory for the execution of works on the reconstruction of the facilities, which are performed on the basis of the decision approving the execution of those works.

It is made for the purpose of obtaining a use permit, use and maintenance of the facility. The design of the constructed facility is made for all facilities for which a building permit is obtained.

The project of the constructed facility is a project with changes that occurred during the construction of the facility.
