DECLARATION
Ministry of Forestry and Water Management of the Czech Socialist Republic
of 9 June 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 Czech Socialist Republic provides pursuant to § 41 paragraph 1 (c) of Act No. 138 / 1973 Coll., on Water (Water Act), and § 10 paragraph 5 of the Act of the Czech National Council No. 130 / 1974 Coll., on State Administration in Water Management:
This Decree provides for technical supervision which is required on dams, hedges and dams, as well as as as parts of structures intended for the treatment of watercourses, flood protection, navigation purposes, water collection, waste water discharges and other use of water, as well as on their built-up tanks (hereinafter referred to as "works') to provide administrators (owners, users and, where appropriate, investors) of such works (hereinafter referred to as" administrators') and technical safety oversight carried out by national committees on the 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 the construction or reconstruction and throughout the 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 by this decree to the administrator.
Categories of works
(1) For supervisory purposes, works are to be classified in categories I to IV. The category of the work shall be determined by the Ministry of Forestry and Water (hereinafter referred to as "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 accompanied by an expert opinion from the organisation responsible for the supervision (hereinafter referred to as the "delegated 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 shall propose to the Ministry an examination of the specified category of work.
Principles of supervision
(1) In the context of supervision, the following phenomena and facts shall in particular be monitored by type and type of work, category and technical condition as appropriate:
(a) the static and dynamic stability of the work or parts thereof;
(b) spatial changes of the work as a whole in relation to 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, continuity, direction and speed of water flow, partial and total amount of leakage, 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;
(i) the effects of the environment on the technical condition of the work and its technological equipment, i.e. the effects of the weather (especially frost and waves), the slides of the banks of the tank and slides in the vicinity of the work, the aggressive effects of air and water in the tank, the groundwater and the sewerage, the effects of construction and blast works around the work, earthquakes, undermines, operational and transport shocks, vegetation and animals and the unauthorised intervention of third parties;
(j) the effect of 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 discharge, the overflows and the sampling facilities;
(k) flow rates compared to the original assumptions of the design of the discharge and tidal devices, e.g. influencing the flow on the top stream by new parts or by failure or by cancelling existing works, changing the outflow rates in the basins, ice jams, vegetation;
(l) 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 and processing, analysing and evaluating the results of all observations and measurements in relation to a predetermined limit (1) or critical m2) of values, project assumptions, building knowledge and existing work operations.
(2) The basis for the supervisory exercise shall be the effectively distributed monitoring of the facts, including routine measurements of quantities and phenomena which 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 installed instruments, the scope and frequency of the work shall be proportionate to the category of work, the state and operation of the work, or 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 required to transmit 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. As regards the works of Category I and Category II, 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, the period of verification of the partial and total work and the period of continuous operation of the phase and aggregate 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 required to provide the submission through an authorised organisation.
If, during the construction or reconstruction of the work, the supplier uses the construction or reconstruction technology that temporarily creates a construction that retains or can detain water, the supplier shall have, in relation to that part of the construction or reconstruction of the supervisory obligation imposed by this decree, the AIFM.
Scope of supervision for individual categories of works
(1) For Category I works, all phenomena and facts whose change may objectively indicate or cause project assumptions to be exceeded to such an extent that the degree of stability of the work or a significant part thereof would fall below the permissible limit of the 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 must 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 multiple measurement methods.
For Category II works, the scope of supervision is the same as that of Category I works, with no need to monitor phenomena and facts whose existence or, where appropriate, a disproportionate change, may be derived in due time from another phenomenon or aggregate expression, such as total leaks, 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 observed 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 required to attach an opinion on the scope of supervision from the entrusted organisation to the project task of building or reconstruction of Category I to III works; for Category IV works, the expression on the scope of supervision shall not be processed.

(c) requirements for future means of supervision, instruments and equipment for observation and measurement;
(d) requirements for means of communication, warning and signalling equipment for supervisory purposes, as well as emergency measures for construction and operation;
(e) an indicative estimate of the costs of the means of supervision and their performance in the construction or reconstruction and in the operation of the work.
(1) For Category I or Category II works, the administrator shall ensure, at the same time as the project documentation, the processing of the measurement project at the level in which the project documentation is processed. For Category III works, the administrator shall provide the measurement project only where the designated organisation proposes this in an opinion on the scope of supervision; the measurement project is not provided for Category IV works.
(2) The measurement project must be based on an opinion on the scope of supervision, the requirements of the relevant technical standards and the principles of supervisory conduct (Sections 4 and 5).
(3) The measurement project shall include, in addition to the documentation of control instruments and equipment, in particular:
(a) an overview of the important assumptions for the safety and stability of the long-term operation of the work and an estimate of their security;
(b) design and justification of the type, scale and accuracy of the measurement methods and instruments and equipment used to carry out supervision;
(c) an overview of the limit values of the observed phenomena and facts affecting the safety of the work and its endangered territory;
(d) the design of safe access to measuring equipment and measures to ensure the safe performance of measuring and maintenance of measuring equipment, including their protection against damage;
(e) a timetable for installation and first measurements according to the construction process.
(4) If some of the requirements set out in the opinion on the scope of supervision are not addressed in the measurement project, they shall be reflected in another part of the project documentation.
