Technical documentation of the investment

Each investment requires precise determination of the designed elements, the scope of implementation works, material calculations, equipment needed and cost arrangements. For this purpose, technical documentation is compiled. Execution, checking and approval of documentation is entrusted to properly prepared and experienced employees. Technical documentation is necessary to decide on the commencement of works and enables the development of schedules, ordering materials, equipment preparation rooms and organizing a team of employees.
The documentation is prepared on the basis of the applicable regulations regarding the design of investments and on the basis of current industry instructions.

The technical and economic assumptions of the investment are a set of arrangements that define the goal, program, the nature of the investment, methods of implementation and cost. The assumptions contain a graphic part, descriptive and economical.

The graphic part presents:
- links with other objects, on the basis of the general spatial development plan,
- existing elements in a given area (armament, vegetation),
- general spatial-artistic concept with the arrangement of the planned elements.

The descriptive part usually includes:
- justifying the choice of specific solutions and concepts,
- investment description, existing items, -topography, program, anticipated devices and attendance.

The economic part at this stage of the study is to determine the approximate cost of the investment. It is calculated on the basis of the catalog prices of the designed elements and on the basis of unit cost indices determined according to the costs of similar objects realized. These data are collected in a summary (a statement of construction costs.

Technical and economic assumptions are prepared by the investor. Once approved, it delivers to the design body.

SIMPLIFIED DOCUMENTATION
This type of documentation is made for simple investments, e.g.. small green areas or street lanes, which do not require detailed studies. This type of documentation is often called single-radio, because it consists only of a technical design based on simplified assumptions. Simplified documentation consists of, just like technical documentation, from the graphic part, description and cost estimate.

TYPICAL DOCUMENTATION
Striving to reduce costs, speeding up the execution of an element and avoiding errors, it often prompts designers to use existing and proven designs of various elements. The most common are building elements, like for example. fences, concrete poles, benches. Elements produced on a large scale based on typical documentation are very often used, and on sale.
