Investment documentation: DIIP, PIZ and IP

Depending on the complexity of the project and the estimated value of the investment, the necessary investment documentation must be prepared in accordance with the Decree on the uniform methodology for the preparation and treatment of investment documentation in the field of public finance.

Basis:

• In principle, no project documentation is required for the preparation of DIIP or a conceptual design is sufficient, depending on the stage of the project cycle and the project value.
• Preparation of an investment programme requires, as a minimum, a preliminary design under the law governing construction, or another conceptual document as a technical, technological or other basis for the preparation of an investment programme, which must contain all the elements and findings necessary to assess the value and feasibility of the investment as realistically as possible.

Thresholds:

The thresholds, which determine how each type of investment documentation is prepared and handled, with fixed prices that include the value added tax that must be shown separately, are:

• for investment projects with an estimated value between EUR 300,000 and EUR 500,000, at least the investment project identification document is required;
• for investment projects with an estimated value above EUR 500,000, the investment project identification document and investment programme are required;
• for investment projects with an estimated value above EUR 2,500,000, investment project identification document, pre-investment study and investment programme are required;
• for investment projects with an estimated value below EUR 300,000, the investment project identification document is required for:
  • technologically complex investment projects;
  • investments which have significant financial implications over their economic lifetime (e.g. high maintenance cost);
  • investment projects that are (co-)financed from the budget.

For projects with an estimated value below EUR 100,000, the investment documentation may be adapted (simplified), but it should contain all the key elements necessary to make investment decisions and ensure monitoring of impacts.
