DECLARATION
Ministry of Forestry and Water Management of the Slovak Socialist Republic
of 24 November 1975
on the technical and safety oversight of certain water-related works and the technical supervision of national committees
The Ministry of Forestry and Water Management of the Slovak Socialist Republic provides, pursuant to § 41 (1) (c) of Act No. 138 / 1973 Coll., on Water (Water Act), and § 10 (5) of the Slovak National Council Act No. 135 / 1974 Coll., on State Administration in Water Management:
This decree provides for technical supervision which is required at dams, lakes and dams, as well as parts of structures intended for the treatment of watercourses, for flood, navigation, water collection, waste water discharges and other use of water, as well as for the production of tanks (hereinafter referred to as "works'), to provide administrators (owners, users and, where appropriate, investors) of such works (hereinafter referred to as" administrators'), and for technical safety oversight carried out by national committees on works.
Technical and security oversight
(1) Technical technical safety oversight (hereinafter referred to as supervision) is a professional activity to establish the technical state of the work in terms of its safety and stability and possible causes of disturbances and to propose measures to remedy it.
(2) Supervision shall be ensured during the preparation of the work and shall be carried out during construction or reconstruction during the entire period of operation of the work until it is put into harmless condition.
(3) During the period of preparation and construction of the work, the investor fulfils the obligations imposed on the administrator by this decree.
Categories of works
(1) For supervisory purposes, works are to be classified in categories I to IV. The category of the work is determined by the Ministry of Forestry and Water Management of the SSR ("the Ministry ') after consultation with the relevant Regional National Committee.
(2) For works, with the exception of works which were under construction or operation on 1 January 1974, their administrator is obliged to submit a proposal to the Ministry to determine the category of work at the latest before the completion of the project task of construction or reconstruction, or 6 months after the date of application of the decree. The proposal shall be supported by an expert opinion from the organisation responsible for the supervision of the Ministry (hereinafter referred to as "the entrusted organisation '), including the design of the category of work and the criteria used for the design of the category; for works which were under construction or operation on 1 January 1974, the Ministry shall determine the category of work of the administrator's own motion.
(3) When reconstructing or changing the use of the work and in the case of Category III and Category IV works, even where the installation in the territory is changed by a work at risk, the administrator is obliged to propose to the Ministry the examination of the specified category of work.
Principles of supervision
In the supervisory framework, the following phenomena and facts shall in particular be monitored by type and type of work, proportionate to the category and technical condition:
(a) the static and dynamic stability of the work or parts thereof,
(b) spatial changes of the work as a whole towards its surroundings;
(c) deformation of the work, mutual displacement of individual parts of structures, cracks in the construction material;
(d) deformation of the subsoil;
(e) the physical mechanical properties of construction and support materials,
(f) groundwater and leakage water regime, i.e. water pressure, leakage continuity, direction and speed of water flow, partial and total leakage rate, water vents in the space of the work;
(g) the function of the protective, sealing, filtration and drainage elements of the work and its substrates;
(h) hydraulic gradient in structural and ground materials and their filtration stability;
(ch) the effects of the environment on the technical condition of the work and its technological equipment, i.e. weather effects (in particular frost and rippling), landslides of the tank banks and landslides in the vicinity of the work, aggressive effects of air and water in the tank, groundwater and sewerage, effects of construction and blast works around the work, earthquakes, undermines, effects of operational and transport shocks, effects of vegetation and animals and unauthorised interventions by third parties;
(i) the effect of the operation on the technical condition of the work and its technological equipment, i.e. the effects of water handling in the tank, the mechanical and other effects of the discharged water and drifting materials, the wear and possible consequences of the failure of the closures and the paying structures of the discharges, overflows and sampling facilities;
(j) flow ratios compared to the original assumptions of the design of discharge and tidal devices, e.g. influencing the flow on the upper flow of new parts by failure or cancellation of existing works, change in drains in the river basin, ice jams, vegetation,
(k) other phenomena and facts which, according to local circumstances, may affect the safety of the work.
(1) Supervision shall be carried out in particular by observing the work, measuring its deformations, leakage and processing, analysing and evaluating the results of all observations and measurements in relation to predetermined limit values (1) or critical values (2) of the project's assumptions, knowledge of the construction and existing operation of the work.
(2) The basis for the supervisory exercise shall be the effectively distributed monitoring of the facts, including routine measurements of variables and phenomena that are relevant for the safety of the work, as well as rounds, reports and inspections.
(3) The selection of possible causes of defects and other phenomena and the facts that the supervision monitors, the choice of means and methods of observation and measurement, the number of devices installed, the scope and frequency of the work shall be proportionate to the category of work, condition and operation of the work, and, where appropriate, to local circumstances, and shall comply with the applicable technical standards and the current state of engineering knowledge and the possibility of implementation.
(1) For Category I and Category II works, the AIFM shall ensure that supervision is carried out through an authorised organisation, which shall, however, be obliged to submit the supporting documents referred to in Section 5 (2) to the extent specified by the supervisory programme.
(2) For Category III and Category IV works, the AIFM shall supervise itself.
(3) Supervision shall be carried out in proportion to the category of work, at least to the extent laid down in this Decree. In the case of Category I and Category II works, the administrator and the entrusted organisation may agree on a temporary or permanent adjustment of the scope supervision provided for in this Decree.
Surveillance reports shall be drawn up during the period of construction or reconstruction of the partial and summary work, during the period of verification of the partial and total work and during the period of continuous operation of the phase and summary phase report work.
All supervisory reports shall be submitted by the AIFM to the water authority in whose jurisdiction the work is authorised (hereinafter referred to as the "competent water authority '); for Category I and Category II works, it shall be obliged to arrange for submission through an authorised organisation.
If, during the construction or reconstruction of the work, the supplier uses the construction or reconstruction technology to temporarily establish a construction which retains or may detain water, the supplier shall, in relation to this part of the construction or reconstruction, have an obligation to ensure supervision imposed by this decree on the AIFM.
Scope of supervision for individual categories of works
(1) For Category I works, all phenomena and factors whose amendment may objectively signal or cause project assumptions to be exceeded to such an extent that the degree of stability of the work or a significant part of it would fall below the permissible limit set by technical standards. The weather and operational conditions shall be determined to the extent necessary for the assessment of all the phenomena and facts observed.
(2) Measurements should be carried out not only in places characterised by average ratios, but also in places where, above all, discontinuous development of phenomena could occur, such as failures in the foundations, changes in the layout and connection of gaskets and drainage elements.
(3) In doubt about the reliability of the method of monitoring the most important phenomena and facts, the responsible organisation shall determine the use of several measurement methods.
For Category II works, the scope of supervision is the same as for Category I works, with no need to monitor phenomena and facts, the existence of which, or any undue change, may be derived in due time from another phenomenon or aggregate expression, such as total leakage, total deformations or shifts. Measurements are usually concentrated in characteristic profiles. Only weather and operational conditions are detected which immediately clarify the phenomena and facts observed.
For Category III works, supervision shall be carried out by expert evaluation of phenomena and facts and their development, as a general rule only at rounds. Only the measurement of leakage, or water pressures and measurement of total deformations on the surface of the work is introduced from normal measurements. Only precipitation and air temperatures and water levels in the tank are detected from weather and operating conditions.
For Category IV works, supervision shall be carried out by assessing the phenomena and facts found during the rounds. Measurements are introduced only temporarily to clarify unusual phenomena and facts.
Preparation of supervision before construction or reconstruction of the work
(1) The administrator is obliged to attach an opinion on the scope of supervision from the designated organisation to the project task of the construction or reconstruction of the category I to III work; for Category IV works, the scope of supervision is not processed.
